DISCUSSION
We are pleased to offer our FY 2023-24 annual report on the status of the County Auditor-Controller-Treasurer-Tax
Collector’s Internal Audit Division. This report contains a status on our FY 2023-24 Audit Plan, a summary of the FY
2023-24 Whistleblower Hotline reports, and our proposed FY 2024-26 Audit Plan. We are asking the Board to
approve our proposed Multi-Year Audit Plan.
In addition, we’ve included the Internal Audit division’s Final Report on an Employee Procurement Card Fraud
Investigation. This report presents the findings of the employee Procurement Card investigation and outlines the
corrective actions taken in response.
After a criminal investigation into misuse of a County Procurement Card, the Internal Audit Division initiated a
comprehensive review of the County’s Procurement Card program, partnering with our external audit firm to
support the effort. The attached CliftonLarsonAllen LLP Procurement Card Process Assessment details the scope
of work completed with the audit firm, the procedures performed, key observations, and actionable
recommendations for the County to consider.
As a result of the criminal investigation and program review, the ACTTC has implemented several key safeguards
to prevent future misuse, including mandatory segregation of duties, enhanced data analytics and continuous
Page 2 of 3
monitoring of activity, and expanded training for all employees involved in Procurement Card processes. These
policy changes are detailed in the Employee Procurement Card Fraud Investigation Final Report.
OTHER AGENCY INVOLVEMENT
None.
FINANCIAL CONSIDERATIONS
None.
RESULTS
A well-functioning Internal Audit Division inspires and elevates public trust in government by assisting and
supporting the County, the Board of Supervisors and other stakeholders in achieving their mission with integrity
and accountability.

Overview
We are pleased to offer our annual report on the status of the County Auditor-Controller-
Treasurer-Tax Collector’s Internal Audit Division (IAD) in accordance with the International
Standards for the Professional Practice of Internal Auditing requirements. A report on the FY 2023-
24 Audit Plan is included on page 6, a summary of the FY 2023-24 Whistleblower Hotline Reports
is included on pages 6-8, and our proposed FY 2024-26 Multi-Year Audit Plan is included on page

Purpose, Authority, & Responsibility
The Internal Audit Division exists to inspire and elevate public trust in government by assisting
and supporting the County, the Board of Supervisors, and other stakeholders in achieving their
mission with transparency and integrity. We accomplish this vision by providing reliable,
independent, and objective evaluations and advisory services which utilize a systematic and
disciplined approach to add value and improve operations. We contribute expertise in the
evaluation and enhancement of internal controls, minimization and mitigation of risks, and
enrichment of operational effectiveness for stakeholders.
The authority for the Internal Audit Division is provided in California Government Code Sections
26881 and 26883. In Accordance with Government Code Section 1236, we currently follow the
International Standards for the Professional Practice of Internal Auditing (Standards).
Our responsibilities include maintaining independence and objectivity, continually enhancing our
skills and knowledge, and providing consistent, clear communication as we perform our work.
Our audit duties include the performance of:
Assurance Audits – the main purpose of assurance audits is to provide an
objective assessment of evidence and an independent opinion or conclusion
regarding an operation, function, process, system, or other subject matter. Such
audits may focus on the reliability of financial or operational information, on
systems of internal control over recordkeeping, and/or the adequate
safeguarding of assets. These audits may also include a review of controls
implemented to ensure compliance with policies, plans, procedures, laws, and
regulations.
Examples of assurance audits completed in prior fiscal years include:
Cannabis Tax Compliance Audits
Departmental Cash and Internal Control Audits

Transient Occupancy Tax Collection Audits
Consulting Audits – Consulting audits are advisory in nature and are generally
performed at the specific request of a client. The nature and scope of the
consulting engagement are subject to agreement with the client.
Examples of consulting audits in prior fiscal years include:
Department of Social Services’ Workforce Innovation and Opportunity Act
Grant Audit
In addition to our audit duties, the Internal Audit Division is responsible for:
Monitoring the County’s 24/7 Whistleblower Hotline, investigating and following
up as needed
Assisting in the preparation of the County’s Treasury’s quarterly Statement of
Assets reviews
Acting as liaison with the external auditors

Independence
The Auditor-Controller-Treasurer-Tax Collector (ACTTC) is elected by the citizens of San Luis Obispo
County, thus achieving organizational independence. The Internal Audit Division consists of one
staff auditor and one Internal Audit Manager who report directly to the ACTTC. Both the ACTTC and
the Internal Audit Manager have unhindered access to the County Administrative Officer and the
Board of Supervisors.
Each year the ACTTC, Deputy Auditor-Controller, and individual members of the Internal Audit
Division affirm their independence by signing a Statement of Independence and Objectivity.
Likewise, Statements of Independence are completed for each individual engagement by team
members assigned to the engagement.
Internal Audit Division Charter
The Internal Audit Division Charter is the guiding document for our audit work. The Charter
includes the Core Principles for the Professional Practice of Internal Auditing issued by the Institute
of Internal Auditors. No updates to the Charter have occurred in the past fiscal year.
Quality Assurance and Improvement Program Results
The auditing Standards require that we maintain a quality assurance and improvement program
consisting of both ongoing and periodic assessments of our operations and audit work to
determine conformance with the Institute of Internal Auditor’s Definition of Internal Auditing, Code
of Ethics, and Standards.
External Assessment
The Standards specify that an external assessment, also known as a peer review, be conducted
every five years. Our last peer review occurred in FY 2022-23 for the period July 1, 2016, through
June 30, 2022. The Internal Audit Division was awarded a Certificate of Compliance , the highest
possible rating, from the Association of Local Government Auditors recognizing that the
organization’s internal quality control system was suitably designed and operating effectively to
provide reasonable assurance of compliance with the International Standards for the Professional
Practice of Internal Auditing for assurance and consulting engagements during the audit period.
Our next peer review will be performed in FY 2027-28 and will cover July 1, 2022, through June 30,
2027.
Internal Periodic Assessment
Internal assessments are performed to evaluate conformance with the Standards and the
Institute of Internal Auditor’s Code of Ethics. Our recent internal assessment is underway and will
Page 4 of 15
COUNTY OF SAN LUIS OBISPO
Office of James W. Hamilton, CPA
Auditor-Controller Treasurer-Tax Collector Public Administrator
Michael Stevens, Deputy
Justin Cooley, Deputy
ensure the effective implementation of the new Global Standards for the Professional Practice of
Internal Auditing.
Ongoing Monitoring
The Internal Audit Division complied with the ongoing monitoring requirement through soliciting
stakeholder feedback, using checklists and taking advantage of automated systems to provide
assurance that processes had been followed. We also monitored project budgets and analyzed
additional performance metrics, including those reported below.
The results of our ongoing monitoring demonstrate that we are perceived as being professional
and knowledgeable, that our work helps management improve business processes and controls,
and that our recommendations are being implemented.
The Internal Audit Division categorizes audit issues into two levels and provides recommendations
for each issue identified. The seriousness of the issue determines if a departmental response is
required:
Findings – issues which present a serious enough risk to require consideration by
management and a written response to our recommendations. The Internal Audit
Division conducts follow-up monitoring on all issues identified as Findings.
Verbal Recommendations – issues which are lower risk and/or a best practice that
could be adopted to improve controls and/or enhance operations. Verbal
Recommendations do not require a written department response and are not
included in the engagement report.
All Findings and Verbal Recommendations are discussed with the Department’s management
prior to a report being issued. In most cases the department makes a change to address the issue
before the audit is complete. If not, then Findings are followed up within six to twelve months.
FY 2023-24 Internal Audit Plan Status
The annual audit plan is intentionally created with an ambitious goal of completion and with the
realistic understanding that the Division’s time is flexible and continuously changing to adapt to
the needs of the ACTTC’s office and the County as a whole.
The following table details the status of the audits in the FY 2023-24 audit plan.

Whistleblower Hotline Results
The Internal Audit Division monitors the Whistleblower Hotline, refers reports to related
departments or agencies and conducts follow-up investigations as necessary. In FY 2023-24, the
Whistleblower Hotline received 46 reports, a 130% increase from the prior year’s 20 reports. 50%
of the reports received were referred to other County departments. All but two of the reports
were received directly through the Whistleblower Hotline. 20 of the 46 reports received were
submitted anonymously. Three of the reports were investigated by the District Attorney’s office.

Justin Cooley, Deputy
The FY 2023-24 reports received were related to the following categories:
Reports related to employee misconduct that were not related to alleged fraud, waste, or abuse
were referred to Human Resources. The remainder of the reports were either referred, not related
to County operations, unsubstantiated or did not contain sufficient information to investigate.
Quarterly Whistleblower Hotline reports are available on the ACTTC website.
1
Departments with the highest incidence of referred reports for the fiscal year are Human Resources, Health Agency, and the Sheriff’s Department.

In addition to matters originating from the Whistleblower Hotline, the Internal Audit Division also
aided with the investigation of an internal report alleging the misappropriation of County funds
by a county employee. Details for that investigation are attached as special attachments to this
report. Two of the FY 2023-24 Whistleblower reports resulted in employee terminations and
resulted in enhanced internal controls and policy definition at the department level.
FY 2024-26 Internal Audit Plan- Introduction of the Multi-Year Audit Plan
The purpose of the multi-year audit plan is to offer a longer-term, flexible view of audit coverage
that can adapt to changing priorities and resource needs as new risks emerge over time.
The Internal Audit Plan for Fiscal Year 2024-26 summarizes the audits we recommend performing
during the fiscal years. The plan is based on the results calculated by our Countywide risk
assessment, stakeholder input process, and available audit hours based on two full-time
equivalents. It is important to note the plan is a working document and can be adjusted
throughout the year as priorities and risks change.

Risk Assessment
The risk assessment is a systematic process used to evaluate, identify, and prioritize potential
audits based on the level of risk to the County. The audit universe, a range of auditable
components is reviewed and updated. An excerpt of the County’s audit universe is included in the
illustration below. Risk is defined as the possibility of an event occurring that will have a financial
or operational impact on the achievement of the County’s objectives and is measured in terms of
impact and likelihood. The assessment identifies exposures that would disrupt the organization’s
operations, interfere with County and departmental goals and business objectives, and serve as
obstacles in the compliance of local and federal governances.
Stakeholder Input
Development of the plan allows for input from the Board of Supervisors, the County
Administrator, departments, and other public stakeholders. At least annually, input is requested
from the Board of Supervisors, the County Administrator, and departments.

Case Background
In September 2023 the ACTTC’s Internal Audit division became aware of suspected fraudulent
activity on a county Procurement Card used by a county employee. Examination of records
obtained independently from vendors by ACTTC’s Internal Audit unit did indicate transactions for
non-county business, many with altered documentation presented to department officials for
payment approval.
The ACTTC reported the findings to the District Attorney and proceeded with further examination
of historical records in collaboration with District Attorney investigators. The expanded
investigation produced numerous instances of suspicious transactions by the employee, spanning
several years. The investigation culminated in a prosecution by the District Attorney for
misappropriation of public funds, receiving a guilty plea and a sentence of six years in state prison,
and a court order to pay restitution to the County. In addition, since the felonies were committed
during the performance of official County duties, the employee forfeited future Pension benefits
accrued during the commission of the felonies pursuant to the California Public Employees'
Pension Reform Act (PEPRA) enacted in 2013.
Subsequent Countywide Procurement Card Program Review
Upon conclusion of the criminal investigation, the Internal Audit division shifted efforts to a
countywide review of departmental Procurement Card process and practices, engaging the
County’s independent audit firm for assistance. The outcome of that review is documented in a
report attached with this item containing multiple procedural and monitoring enhancements to
consider.
For historical background, the County has used Procurement Cards (aka Cal-Cards) for many
years, and in 2003 the Central Services Purchasing division issued the Purchasing Card Program
policy manual. The policy establishes baseline administrative procedures, internal controls, and
approval requirements which County Departments must follow in using Procurement Cards.
In recent years the use of Procurement Cards by County departments has grown significantly,
both for administrative efficiencies and in some cases because credit cards are the only form of
payment accepted by vendors. The County also saw the use of Procurement Cards expand
Page 2 of 6
COUNTY OF SAN LUIS OBISPO
Office of James W. Hamilton, CPA
Auditor-Controller Treasurer-Tax Collector Public Administrator
Michael Stevens, Deputy
Justin Cooley, Deputy
significantly during the pandemic due to remote work needs and a shift towards paperless
transactions.
Review of Procurement Card transactions has been conducted by the ACTTC’s Internal Audit
division as part of its Cash Control audit program, however, due to the growing amount of activity,
the need for expanded reviews has been a regular item in the ACTTC’s annual audit plan
competing with other demands on Internal Audit’s capacity.
For the review, the ACTTC engaged its independent audit firm CliftonLarsonAllen LLP (CLA) in April
2024 to collaborate in defining procedures and scope. The engagement began with data analysis
including 58,025 credit card transactions over a 6-year period, from 357 cardholders totaling over
$16M, across 25 departments. From these transactions nine individual departments were
selected for in-depth process reviews with specific transitions flagged for examination.
Department reviews included in-person interviews, procedural observations, and transaction
testing for compliance with County policies.
While the review was not intended to identify improper use of credit cards, no instances of
improper transactions were noted during the review. The intent was to evaluate credit card
practices and did identify numerous opportunities for strengthened controls, oversight, and
monitoring. In many cases procedures observed in certain departments were identified as
recommended practices for rollout across departments. CliftonLarsonAllen LLP’s final report
(attached) details the scope of work, procedures performed, observations, and recommendations
in the following broad categories:
• Suggested Policy Updates
• Suggested Best Practice Guidance to Departments
• Training for Cardholders
• Training for Accountants (Approvers or Coordinators)
• Training for Operational Approvers
• Training for Department Heads
All report recommendations are under consideration by the ACTTC and the Central Services
Purchasing division for implementation. Each will be evaluated with consideration to cost/benefit,
feasibility for departments, and the County’s risk tolerance, however, the following three areas

COUNTY OF SAN LUIS OBISPO
Office of James W. Hamilton, CPA
Auditor-Controller Treasurer-Tax Collector Public Administrator
Michael Stevens, Deputy
Justin Cooley, Deputy
have been elevated as the utmost priority for implementation and will form the foundational
controls over the County’s Procurement Card program going forward:
#1 - Mandatory Separation of Duties for Procurement Card Purchases
During its review, the ACTTC observed instances where individual department staff were
performing all stages of a purchasing transaction, including independent control over the
submission of supporting documentation to the department’s designated “Approving Official”
for review and transmission to the ACTTC for payment. The ability for one individual to control
an entire transaction chain greatly limits the opportunity for checks and balances and increases
the likelihood that improper transactions may go undetected.
Going forward, individual credit card purchases will require certifying signatures by no less than
two individuals within the transaction chain (requested by, ordered by, received by, etc.) for
review by the department’s “Approving Official” before presentment to the ACTTC for payment.
Additional signatures may be required for high-risk purchases such as portable technology or
high-dollar purchases (and departments may institute additional sign-off requirements).
Electronic signature tools (such as Adobe) will be leveraged to make signature captures efficient
for department processing and will also provide a permanent electronic log of signatures for
review by Internal Audits.
The ACTTC will work individually with Departments to institute this new requirement over the
coming months.
#2 - Continuous Monitoring of Procurement Card Transactions
A significant outcome of the review was the development of a Power-BI transaction analytics
tool which the ACTTC is now using to centrally monitor Department Credit Card activity on an
ongoing basis. Initially built by CLA to analyze historical transactions for identification of test
cases for the review engagement, the tool was expanded (with the assistance from County IT
staff) to intake transactions directly from the Procurement Card processor on a monthly basis
for monitoring by the ACTTC.

This level of transaction detail was not previously available to the ACTTC without requesting
paper backup from departments, and could only be reviewed manually on a case-by-case basis.
The Power-BI tool enables the automated analysis of large volumes of native transactions and
flags anomalies based on criteria set by the Internal Audits unit for further review.
Another limitation to centralized transaction monitoring was the practice of storing source
documentation (invoices, etc.) in paper form off-site in department locations. The only data
provided to the ACTTC was summarized credit card statements submitted with the
department’s approval to pay. Supporting paper invoices were not provided to the ACTTC due
to practical limitations such as limited technical scanning and electronic storage capabilities,
physical storage space, and efforts for department staff to copy, attach, and deliver paper
support to the downtown ACTTC office.
As part of the review, new procedures have been developed leveraging current paperless
scanning technologies most departments are now using. Going forward, electronic scans of all
individual transaction invoices will be required with Purchasing Logs provided to the ACTTC for
payment. This will allow the ACTTC to efficiently and independently review any transactions
flagged by the analytical tool.
The ACTTC will work individually with Departments to institute this new requirement over the
coming months.
#3 - Expanded User and Approver Training Programs
Ongoing training is a critical element to support compliance with all fiscal policies, particularly
given staff turnover in Departments. Procurement Card policy guidance currently exists only in
the form of the 2003 written policy document. Capabilities for on-demand video training
curriculum, with Q&A and course completion logs, are being explored by Central Services’
Purchasing division and ACTTC, with the support of Human Resources Learning and
Development Center, with the goal of developing a variety of training and policy reinforcement
tools. Additionally, the ACTTC will add Procurement Card policy overviews to the annual fiscal
training session delivered to Department fiscal staff.

While no system of internal controls can provide absolute assurance that no fraud will occur, we
believe these policy and procedure enhancements will greatly enhance the oversight of
Procurement Card purchases across County departments, in an administratively efficient manner
for department operations.
The ACTTC wishes to express its appreciation to the District Attorney, County Counsel and Human
Resources departments for their professionalism and collaboration throughout the investigation,
as well as the Central Services Department and CliftonLarsonAllen LLP for their collaboration in
the development of policy improvements outlined in this report.

RE: Procurement Card Process Assessment
Dear Mr. Hamilton:
CliftonLarsonAllen LLP was retained by the County of San Luis Obispo (“SLO County”), to perform
risk assessment procedures and provide consultation services with regard to the above
referenced matter.
We have been asked to provide our services in this matter specifically related to, but not limited
to, a risk assessment of the procurement card usage and processes at a selection of SLO County
departments. The purpose of this report is to summarize the results of our work, including the
risk areas identified and recommendations for improvements to processes to help mitigate the
risks of significant fraud.
We performed our engagement in accordance with the Statement on Standards for Consulting
Services, Consulting Services: Definitions and Standards (codified as CS Section 100 in AICPA
Professional Standards) of the American Institute of Certified Public Accountants (“AICPA”). In
consulting engagements, the nature and scope of work is determined solely by the agreement
between the practitioner (CLA) and the client (SLO County). This report does not constitute an
audit, compilation, or review, in accordance with standards of the AICPA, the objective of which
would be the expression of an opinion on any specified elements, accounts, or items. Accordingly,
CLA does not express such an opinion.
Because of the unique nature of fraud, and because our engagement was limited to the matters
described in the Statement of Work, fraud and/or financial irregularities may exist within the
organization that we may not have identified during the performance of our procedures.
However, if during the performance of our services other matters had come to our attention
suggesting possible financial improprieties and/or irregularities, we would have communicated
such matters to SLO County.
Respectfully submitted,
CliftonLarsonAllen LLP

EXECUTIVE SUMMARY | 1
1. Executive Summary
On April 24, 2024, the County of San Luis Obispo (“SLO County”) retained CliftonLarsonAllen
LLP (“CLA”) to perform a process assessment related to procurement cards in use at several
departments within SLO County. CLA assessed the processes in place at nine of SLO County’s
25 departments by interviewing 26 individuals in various roles within those departments. CLA
also selected a sample of 61 transactions from procurement card holders in those
departments and obtained and reviewed the supporting documentation provided by the
respective departments. Additionally, we obtained and reviewed the procurement card
policies in place during the scope period of the previous six fiscal years, July 1, 2018, through
June 30, 2024.
CLA collaborated with our data analytics team to analyze the procurement card activity for all
departments for the scope period. The analysis performed informed the department selection
for process review and sample transaction testing. Additionally, the data analytics team
prepared a Power BI dashboard to aid in historical and ongoing analysis and review. CLA has
provided SLO County access to this dashboard for ongoing monitoring efforts.
After performing the initial data analytics on the procurement card activity, CLA staff spent
one week on site with the various SLO County departments selected for further review. As a
result of this week of on-site interviews, detail review of processes, and sample testing, we
developed 5 observations and 18 recommendations for policy improvements and additional
training for individuals in various roles in the procurement card process.
Several departments are already following both the SLO County policies and additional
procedures they have put into place within their departments to aid in maintaining a
complete documentation file for all procurement card purchases. However, CLA noted that
use of the procurement cards in most departments we interviewed have been utilizing the
cards for ease of purchasing rather than investing adequate time planning and using an
alternate procurement method. The procurement cards should only be used when other
procurement methods are not feasible. Additionally, due to the decentralized nature of the
departments, there are limited centralized processes being followed by the departments,
which has resulted in significant reliance being placed on the departments to monitor their
own procurement card activity. Our recommendations include suggestions for increased
oversight and monitoring both at the department level and the County-wide level.
This project was conducted as a risk assessment of the SLO County’s processes related to the
use of procurement cards by departments and individuals. This project was not an
investigation of procurement card activity and was not intended to identify potentially
improper use of the procurement cards.
It is the responsibility of SLO County to determine which of the recommendations included in
this report will be implemented and the specific processes to be implemented. There is no set
of internal controls that can provide absolute assurance that no fraud will occur, and SLO
County should consider the costs and benefit of implementing each recommendation, and
how they align with SLO County’s risk tolerance.

SCOPE OF WORK | 2
2. Scope of Work
In late 2023, SLO County officials became aware of suspected fraudulent activity on the
procurement card in use by a member of the Information Technology department. After an
investigation into the activity by the SLO County Office of the Auditor-Controller (“Auditor’s
Office”) and the District Attorney, the case was prosecuted by the District Attorney. The
individual pleaded guilty to seven felony counts of misappropriation of public funds from April
2017 to October 2023 on July 17, 2024. This recent identification of fraud on the SLO County
procurement card led officials to prioritize a countywide review of the procurement card
processes and sample testing of transactions at departments with significant spending on
their procurement cards. CLA was engaged to assist SLO County’s Auditor’s Office in this
review.
The scope period for the procurement card process assessment is the most recent six fiscal
years, spanning from July 1, 2018, to June 30, 2024.
Data analysis was performed on the entire population utilizing a Power BI dashboard
developed by the CLA data analytics team. The population of procurement card transactions
included 58,025 transactions by 357 cardholders in 24 departments, totaling over $16 million,
as shown below.1

Facilities Management 593,923.80 County Counsel 49,562.79
Total Spend During Scope Period $16,226,464.40
While data analysis was performed on the entire population of procurement card
transactions, a sample of departments were selected for a more in-depth review of processes
followed. Additionally, a sample of transactions was selected for each of these departments
identified through the data analysis for detailed testing for adherence to SLO County’s policies
and department expectations.
1 These figures exclude all transactions made by the individual who made fraudulent transactions on the SLO County
procurement card, whether the transactions were identified as fraudulent or not.

SCOPE OF WORK | 3
The following departments were selected for detailed process review and sample transaction
testing:
Department # of Cardholders During Scope Period
1 County Fire 36
2 Sheriff Coroner 10
3 Health Agency 63
4 Social Services 29
5 Public Works 22
6 Administration 18
7 Central Services 11
8 Information Technology 15
9 Library 18
These departments were selected based on specific cardholders, vendors, and transactions
identified that were high in volume or had the potential for personal misuse. These
transactions included high spending at retailers such as Amazon, Apple, Target, and Wal-Mart,
a significant increase or decrease in usage, purchases of what appeared to be gift cards (round
dollar transactions), high volume on weekends, and transactions at restaurants, hotels, and
other potentially travel-related vendors.
Our sample transaction review did not include verification that the funding source was
appropriate for the purchases tested. Additionally, this project was conducted as a risk
assessment of the SLO County’s processes related to the use of procurement cards by
departments and individuals. This project was not an investigation of procurement card
activity and was not intended to identify potentially improper use of the procurement cards.

PROFESSIONAL STANDARDS FOLLOWED BY CLIFTONLARSONALLEN | 4
3. Professional Standards Followed by CliftonLarsonAllen
The overall scope of work and approach was conducted utilizing standards in accordance with
the Statement on Standards for Consulting Services, Consulting Services: Definitions and
Standards (codified as CS Section 100 in AICPA Professional Standards) of the American
Institute of Certified Public Accountants (“AICPA). In consulting engagements, the nature and
scope of work is determined solely by the agreement between the practitioner (CLA) and the
client (County of San Luis Obispo). This report does not constitute an audit, compilation, or
review, in accordance with standards of the AICPA, the objective of which would be the
expression of an opinion on any specified elements, accounts, or items. Accordingly, CLA does
not express such an opinion.
Because of the unique nature of fraud, and because our engagement was limited to the
matters described in the engagement letter, fraud and/or financial irregularities may exist
within the organization that we may not have identified during the performance of our
procedures. However, if during the performance of our services other matters had come to
our attention suggesting possible financial improprieties and/or irregularities, we would have
communicated such matters to the SLO County.
The professional standards promulgated by the AICPA prohibit CLA from rendering an opinion
as to whether there has been any fraud or other criminal activity by anyone associated with
this engagement. Therefore, CLA does not render such opinions.

SUMMARY OF WORK PERFORMED | 5
4. Summary of Work Performed
On April 24, 2024, SLO County retained CLA to perform a procurement card process
assessment related to the use of procurement cards at several departments throughout SLO
County, including testing of a sample of transactions. As part of this engagement, CLA
performed the following procedures:
1. Obtained and reviewed procurement card policies and procedures in effect during the
scope period of FY19 through FY24.
2. Obtained a database of procurement card transactions for all cardholders and all
departments during the scope period of FY19 through FY24.
3. Utilizing a Power BI dashboard built by the CLA data analytics team, performed data
analysis on the population of transactions to inform the selection of departments and
transactions for additional detailed review and testing.
4. Conducted interviews with 26 individuals across nine departments to gain an
understanding of the processes followed within their respective departments and roles
(cardholder, approver, or coordinator).
5. Obtained and reviewed documentation for 61 transactions from the various departments
selected for detailed testing to assess transactions for adherence to SLO County policies
and departmental expectations.
6. Documented observations throughout interviews and sample testing to inform SLO
County of possible non-adherence to policies or potential need for increased training or
updates to policies.
As part of this engagement, CLA developed a Power BI dashboard to enhance SLO County’s
ability to analyze and manage employee procurement card usage. This dashboard represents
a significant advancement in procurement card governance, providing SLO County with a
centralized and accessible platform to monitor procurement card transactions across all
departments. The dashboard is designed to empower SLO County with insights needed to
maintain a high standard of financial stewardship, ensuring transactions are in alignment with
SLO County’s established procurement card policies and guidelines.
The data for the dashboard is primarily sourced from two datasets: the US Bank Transactions
Detail Summary and the US Bank Declined Transactions Authorization Summary. Data was
collected covering the scope period. The data extraction encompassed all Agents, Companies,
Divisions, and Departments within Bank 1425, in alignment with the account list provided by
SLO County. Utilizing these two data sources, CLA compiled a comprehensive list of vendors
with whom transactions occurred. Vendor names were normalized using standard data
practices, including trimming leading and trailing spaces, removing store numbers,
eliminating URL components, and other similar adjustments.
County of San Luis Obispo
CliftonLarsonAllen LLP Procurement Card Process Assessment
Page 8 of 19
SUMMARY OF WORK PERFORMED | 6
The source data can be updated and refreshed through various methods: manually, using an
attended Power Automate Desktop flow, using an unattended Power Automate Desktop flow,
or via an API. CLA has provided detailed information on each of these options to assist SLO
County in making an informed choice.
This newly developed dashboard serves as a powerful resource for gaining a comprehensive
understanding of SLO County’s procurement card expenditures. It offers an overview of all
procurement card transactions, along with a detailed analysis segmented by cardholder,
department, vendor, and MCC classification. It also includes an analysis of specific
transactions and declined transactions. Additionally, the dashboard features a risk analysis of
transactions using Benford’s Law, outlier detection, and identification of duplicate and round
dollar transactions.
The dashboard is currently hosted on a secure Microsoft Power BI workspace within the CLA
tenant. The dashboard’s user-friendly interface allows for intuitive navigation, ensuring that
the users can quickly access the information they need for thorough analysis. This dashboard
aims not only to boost transparency in SLO County’s procurement card usage information,
but also empower users to make informed, data-driven decisions.
This dashboard is more than just a tool – it is a strategic asset that will benefit SLO County for
years to come. It provides a solid framework for improved oversight of procurement card
usage, allowing SLO County to monitor procurement card transactions with greater precision
and confidence.
The results of work performed, our observations, and our recommendations are included in
the sections below.

5. Observations
Based on the above procedures performed, CLA identified the following observations in the
processes performed at the various departments interviewed and through detailed testing of
the sample of transactions selected.
A. Assessment of Department Processes
1. While most individuals interviewed understood the SLO County procurement card
policy, there were certain instances in which the policy was not properly understood
or followed.
All nine departments interviewed were aware of the countywide policy in place for use of
the procurement card. Individuals interviewed were aware, generally, of the intended
uses for the procurement card and aware of the types of purchases that are prohibited.
However, there was mixed understanding of the transaction limits, splitting purchases,
and determination of the correct procurement method. While some individuals
understood their transaction and monthly limits for the procurement card, they did not
understand the purpose of those limits in choosing the correct procurement method. This
resulted in cardholders splitting purchases among multiple transactions to avoid the
transaction limit and still make large or recurring purchases with the procurement card.
According to SLO County procurement policies, these types of purchases should be made
through procurement methods other than the procurement cards.
While all individuals interviewed were aware of the policy against sharing procurement
cards, a couple individuals admitted to occasionally providing the card in their name to
other individuals.
Finally, completeness and accuracy of the purchasing log varies amongst departments.2
Some departments utilize accounting staff within their department to assist with
completing the purchasing log, while others rely on the knowledge of the accounting staff
at the countywide level to catch errors in portions of their purchasing log that they may
not have the knowledge to complete themselves. Understanding of the importance of
details included in the purchasing log, such as sales tax, is not consistent across
cardholders in all departments interviewed. This occasionally results in adjustments being
required. Additionally, some cardholders complete their purchasing log in summarized
form for certain purchases they deemed to be related. The combining of transactions into
subtotals in the purchasing log can result in difficulties reconciling the log to the monthly
statement. While CLA did not find any reconciliation discrepancies in the sample of
transactions tested, not including the full details of each transaction separately in the log
can make reconciliation and review less efficient.
2 The purchasing card log is a County document that is completed by each cardholder for each billing period (month)
and includes for each transaction the following fields: date, vendor, description, cost center, general ledger account,
functional area, internal order number, dollar amount of item, shipping, handling, sales taxes, tax code/type of tax,
vendor state, status of billing, and total dollar amount of transaction.
County of San Luis Obispo
CliftonLarsonAllen LLP Procurement Card Process Assessment
Page 10 of 19
OBSERVATIONS | 8
To address these observations, CLA recommends conducting training sessions for
cardholders, approvers, coordinators, and department heads (Recommendations 12-16
below).
2. Certain departments set additional expectations for their cardholders that the SLO
County may benefit from adopting countywide.
At some departments, CLA noted unique processes being followed that were not defined
with any specificity in the countywide procurement card policy. These included
documented prior authorization for purchases on an internal requisition form and
documentation of receipt of goods.
While documented prior authorization for a purchase is not required according to the
countywide policy, multiple departments are utilizing their own internal department
forms to document the purchase request and authorization before the cardholder makes
the transaction. This document is then included with the receipt in the monthly packet by
the cardholder. Other departments are using e-forms for purchase requests to aid in
internal routing of the purchase to the cardholder. Some departments are using a form
for only the purchase request, while others are using forms to document both the request
and the approval by a supervisor.
Additionally, some departments are consistently documenting the receipt of goods
purchased with the procurement cards. The form of this documentation varies from
department to department depending on the needs of the employees within the
department. Some departments have a centralized purchasing process where only one or
two individuals handle procurement card purchases, making the documenting of receipt
of goods for the department more necessary. Other departments have multiple
cardholders in operations roles making purchases for themselves and their team
members, reducing the need to formally document the receipt of goods purchased.
CLA recommends requiring departments implement segregation of duties between the
cardholder and the receiver of delivered goods or increased compensating controls
(Recommendation 2 below).
B. Results from Sample Testing
CLA selected a sample of 61 transactions from the population of 58,025 transactions
during the scope period, spanning 16 cardholders at nine departments, to review for
adherence to procurement card policies, sufficient documentation for purpose of
purchase, and overall reasonableness of transaction. Only a small sample was selected as
the primary objective was to assess whether processes were being followed as required
by the SLO County policies and communicated by departments. To select the 61
transactions, CLA focused on identifying cardholders and departments with a high volume
of usage in general and at certain retailers. These identified higher risk types of usage
included spending at Amazon, Apple, Target, and Wal-Mart due to the nature of
purchases available at those retailers. CLA also focused on selecting departments and
cardholders with significant increases or decreases in usage, purchases of what appeared

OBSERVATIONS | 9
to be gift cards (round dollar transactions), high volume on weekends, and transactions
at restaurants, hotels, and other potentially travel-related vendors.
The testing criteria included validating the following:
1. Purchase was below the per transaction spending limit of $4,950.
2. Purchase was approved according to policy by signature of approving official on both
the monthly statement and the purchasing card log.
3. Documentation provided by the cardholder supports the purchase by including all
relevant details of the purchase on the documentation and ensuring those details
agree between the documentation, the monthly statement, and the purchasing card
log.
4. Documentation provided by the cardholder agrees to the description included in the
purchasing card log.
5. Documentation provided by the cardholder includes evidence of prior authorization
for the purchase (not required by SLO County policy but performed by some
departments as communicated in interviews).
6. Purchase appears reasonable based on the cardholder's department and position and
context included in the supporting documentation.
7. Purchase was not a prohibited transaction listed in the Purchasing Card Policies and
Procedures document in effect at the time of purchase, unless specifically approved
prior to the purchase.
8. Purchase does not appear to be a split purchase to circumvent transaction limits.
9. If purchase was for goods, evidence of receipt of goods is included in the supporting
documentation provided by the cardholder (not required by the SLO County policy
but performed by some departments as communicated during interviews).
10. If no receipt was provided by the cardholder, a Missing Receipt Form was completed
and signed by the proper individuals.
11. Overall, the transaction appears reasonable and appropriate and includes sufficient
information and documentation to support the purchase.
CLA observed the following non-compliance with SLO County policies as described below.
3. Insufficient documentation or information was included with the supporting
documentation for some purchases. In some instances, while a detailed receipt was
included, a reasonable explanation of the nature and purpose of the purchase and
how it related to business of SLO County was lacking.
In nine of the 61 transactions reviewed, CLA observed that insufficient information and
documentation was included in the monthly packet provided by the cardholder to
determine the context or intended use of the purchase. These transactions spanned from
July 2018 to April 2023 and were present with six cardholders in five departments. The
descriptions of the purchases are such that a reasonable person might consider them
personal in nature without additional context. SLO County is responsible for services such
as fire and police protection, social services programs, and other community services. Due
to the nature of these services, legitimate purchases to administer the programs could
appear personal. Additional context from the cardholder is important, especially for these
County of San Luis Obispo

types of purchases, to document the relevance to the service being provided. CLA
recommends requiring complete supporting documentation for each purchase and
providing all documentation to the central Accounts Payable office each month
(Recommendation 5 below).
During interviews with cardholders and approvers at various departments, CLA learned
that many departments are increasing the amount of documentation and information
gathered and included in the monthly cardholder packets up front, rather than providing
only in response to questions later. Because the sample selected included transactions
incurred several years prior, not all transactions were subject to recent processes
implemented by departments.
In one instance of the 61 transactions reviewed, CLA observed that an itemized receipt
was not included in the documentation provided by the cardholder for the purchase. This
is in violation of the policy requiring itemized receipts containing all relevant information
for the purchase. This transaction occurred in August 2019.
In one instance, CLA observed that no Approving Official signature was obtained on the
monthly Purchasing Card Log, as required by SLO County policy. This instance occurred in
October 2023. CLA recommends not only reinforcing that these signatures are required
but also specifying the type of signature that is appropriate (Recommendation 3 below).
In one instance of the 61 transactions reviewed, CLA observed that prior approval for a
purchase of gift cards was not properly obtained. While gift cards are a prohibited use for
the procurement cards, they may be purchased if prior approval is granted by the SLO
County Auditor’s Office.3 In this instance, no prior approval was documented as granted
by the Auditor’s Office. This transaction occurred in July 2023. Each department
purchases gift cards as they determine their needs and makes the purchase from retailers
of their choosing with their own department procurement cards. CLA recommends
continuing to require prior approval and tracking of all gift card purchases. Additionally,
CLA recommends considering if alternative methods of purchasing gift cards is possible
to centralize and create increased transparency around the process (Recommendation 6
below).
4. Prohibited transactions were identified.
In one instance of the 61 transactions reviewed, CLA observed that a personal online
account was used to make a purchase on the procurement card. This is prohibited per the
SLO County policy. The transaction was through eBay, which the County does not have an
official account with. This transaction occurred in July 2023.
3 Gift cards may be approved for purchase to further the objectives of certain community service programs such as the
safe parking program, incentives for participation in surveys or vaccines, and victim witness needs. Gift cards approved
for purchase are required to be tracked using a gift card log. All transactions tested that were for the purchase of gift
cards had properly completed gift card tracking logs.
County of San Luis Obispo
CliftonLarsonAllen LLP Procurement Card Process Assessment

OBSERVATIONS | 1 1
In seven of the 61 transactions reviewed, CLA observed evidence that the purchase was
split into multiple transactions to avoid the per transaction limit of $4,950, which is
prohibited per the SLO County policy. In each instance noted, an alternative procurement
method should have been used. These transactions spanned from October 2023 to April
2024 and were present with three cardholders in two departments.
Additionally, in six of the seven split transactions noted above, CLA observed evidence
that the equipment purchased should likely have been capitalized either on its own or as
part of a larger asset purchase. Due to these purchases being made on the procurement
card, they were not properly tracked as possible capital asset additions. These
transactions were present with two cardholders in one department. CLA recommends
requiring tracking of small equipment purchases to assist in identifying items that may
need to be capitalized as part of a larger asset (Recommendations 7 and 18 below).
5. Department-specific requirements were not always followed.
While the following observations were not SLO County policy violations, CLA noted that
specific requirements within some departments were not met in two instances within the
sample of 61 transactions reviewed.
In one instance, no internal department-required requisition form was completed and
maintained as documentation for the purchase made. In a separate instance, no evidence
of the receipt of goods ordered was documented for the purchase, as expected by
department practice.
Summary of Observations
In the sample of 61 transactions reviewed, CLA noted observations in 22 instances. 20 of
those instances were SLO County policy violations and two were department-specific
requirements not being met but not SLO County policy violations.
SLO County Policy Violations:
Description Instances
Not enough information provided 9
Evidence of split transaction 7
Personal online account used 1
No approval documented on purchasing card log 1
No itemized receipt retained 1

CLA also observed that the documentation method of cardholder and approver sign offs
was inconsistent over time and across departments. The sign offs varied between wet
signatures, typed names, and digital signatures. SLO County policy does not dictate the
required method for the cardholder and approver sign offs, so CLA did not identify policy
violations in this matter. However, CLA recommends that the method for signature be
specified as a method that cannot be easily copied, such as a wet signature or digital
signature using Adobe, DocuSign, or a similar digital signature program (Recommendation
3 below).
CLA understands that the SLO County Auditor’s Office has not previously had the ability
to monitor procurement card activity across the County as a whole. However,
implementation of a Power BI dashboard is in progress and is expected to be used for
ongoing monitoring by not only the Auditor’s Office but by department management as
well (Recommendation 17 below).

6. Recommendations
Based on the work performed by CLA as described above, we make the following
recommendations to SLO County.
A. Countywide Purchasing Card Policy Considerations
Suggested Policy Updates
1. Establish a process for monitoring and enforcing compliance with the Purchasing Card
Program policy, including which departments (Purchasing Department, Auditor’s
Office, or individual department head) is responsible for specific monitoring
processes, identification of violations, and administration of consequences. The
process should include to whom violations should be reported and specific
consequences and escalation of consequences for different types of noncompliance
with the Purchasing Card requirements. Consequences may include reassignment of
the card to another employee in the department or deactivation of the card.
2. Require appropriate segregation of duties so that designated individuals other than
the purchaser receive all goods ordered upon delivery. If duties cannot be fully
segregated due to staffing constraints, mitigating or compensating controls should be
established, such as enhanced oversight and review steps.
3. Update policy to define the type of signature that is allowable for both the cardholder
and the approver for both the monthly statement and the purchasing card log.
Consider requiring the signature to be of a method that is difficult to copy, such as a
wet signature or a digital signature using a program such as Adobe or DocuSign.
4. Update the Purchasing Card Program policy to include a definition of an “emergency
purchase,” the designated individuals that can approve an emergency purchase, and
a list of approved vendors. Consider if food purchases may be an emergency purchase
under specific circumstances, and if so, consider specifying those circumstances in the
policy and including a list of approved vendors for those purchases.
5. Require all cardholders in all departments to send a copy of the complete packet of
backup documentation to the central Accounts Payable office or upload to the
accounting software each month. This will ensure that all relevant documentation for
procurement card purchases is centrally located and accessible to the Auditor’s Office
and accounting staff.
6. Consider whether a centralized process for purchasing gift cards could be
implemented that would eliminate the need for individual departments to use
procurement cards to purchase gift cards. This may allow more transparency around
gift card requests, purchases, and distribution.
7. Require that departments maintain inventory records of small equipment purchases
that are under the capitalization threshold but higher than an inconsequential

threshold (such as $500). The inventory should track where the equipment is located
and its expected replacement timeline. This will help ensure that all small equipment
assigned to individuals is returned upon requesting a replacement item or upon
departure from the department. A policy for periodically auditing and verifying the
accuracy of department inventory records should be developed and implemented.
8. Consider updates to the Purchasing Card Log to include calculations of common sales
tax percentages to aid in identifying adjustments that may be required by the
Accounts Payable office. Also consider updates to the log that may be compatible
with exports of the credit card transactions or import functions into the accounting
software, which may reduce the need for data entry in multiple places.
9. Ensure that the Purchasing Card Program policy is reviewed and updated at least
annually, maintained in a centralized location, and made accessible to all County
employees and contractors participating in the Procurement Card program.
Suggested Best Practice Guidance to Departments
10. Consider requiring departments to annually review all cardholders and card limits and
submit the approved list to the Purchasing Department. This will encourage
department heads to take an active role in determining the proper cardholders for
their department and whether lower thresholds should be implemented for certain
cardholders. Included in this annual review should also be the names of the proper
approvers for each cardholder’s monthly statement and purchasing card log. If
separate individuals are required for operational approval versus accounting
approval, those should be defined in this annual review.
11. Encourage departments to identify vendors used regularly with the procurement
cards so they can be evaluated by the Purchasing Department for set up of purchase
orders or contracts. An increase in use of other procurement methods for routine
vendors will reduce the number of transactions on the procurement cards.
B. Countywide Training for Departments Using Purchasing Cards
While the current policy in place requires all cardholders to attend annual training, there
is not currently a thorough training program in place for the various roles individuals hold
within the Purchasing Card Program. CLA recommends not only requiring annual training
for cardholders but also for approvers and coordinators. Training should reiterate the
policies and procedures governing the Purchasing Card Program with recertification of
understanding required. For all individuals involved in the Purchasing Card Program,
annual training should include a continued reminder that they are stewards of public
funds and purchases made using the purchasing cards still require an assessment of
reasonableness of cost even if not going through a competitive quote/bid process.
Therefore, it is important to consider whether the cost of certain items is in the best
interest of SLO County and to be aware of the potential perception surrounding these
purchases. Additionally, consequences for noncompliance with training requirements

should be established, such as reassignment of the card to another employee in the
department or deactivation of the card.
Training for Cardholders
12. Annual training for cardholders should include a review of the intended uses and
prohibited uses of the Purchasing Card. It should also include detailed discussion of
the escalation of consequences for noncompliance with the policy.
Training for Accountants (Approvers or Coordinators)
13. Enhanced training for accountants in each department should be conducted and
include flags and anomalies to look for during the Purchasing Card monthly process
they take part in. Annual training for accountants should also include empowering
them to look for unusual transactions and ask questions of the cardholders. A process
should be implemented for escalating issues beyond the cardholder or department if
questions or concerns are not adequately addressed.
14. Additionally, consider training for departmental accountants around sales tax
calculations, which may reduce adjustments required by the Accounts Payable
Manager after the close of the monthly statements.
Training for Operational Approvers
15. Individuals within each department who are responsible for operationally reviewing
the Purchasing Card transactions should be required to attend annual training
covering the expectations for uses of the card and the specific prohibited uses of the
card. It should be reiterated that they are responsible not only for review of
adherence to policy but also for considering whether the purchase is reasonable and
necessary for the operations of the department.
Training for Department Heads
16. Department heads should also be required to attend annual training to understand
their role in the oversight of spending within their department. They should
understand the policy and procedures in place for the program and within their
department. They are responsible for identifying and approving who has a need for a
Purchasing Card in the department and who will be responsible for the operational
review of all transactions on the card.
C. General Recommendations
In addition to policy updates and guidance and training for individuals involved in the
program, CLA also has the following general recommendations.
17. SLO County should implement use of the Power BI dashboard to perform continuous
monitoring steps. Additionally, SLO County should consider rolling out access to the

departments using procurement cards to aid department leaders in their regular
review of the activity. CLA understands that as of the date of this report, use of the
dashboard is in the process of being implemented.
18. SLO County should consider implementing an item tagging process that includes small
equipment purchases below the asset capitalization threshold. Additionally, this may
include a tracking and monitoring system for computer equipment available through
a hardware vendor such as Dell.
