Why Petty Cash Audits Matter
Petty cash is the easiest line item to lose control of. Small amounts, frequent disbursements, and informal processes add up to a system where mistakes — or worse — go undetected for months.
An audit is how you catch the drift. Whether it's an internal spot-check or a formal review, the point is the same: does the cash in the box match the records? If it doesn't, you need to find out why before the gap grows.
How to Audit Petty Cash Step by Step
This petty cash audit checklist helps ensure that your cash box, receipts, and recorded balance match. Follow each step in order — skipping ahead defeats the purpose.
1. Count the Physical Cash
- Remove all cash from the petty cash box
- Count every denomination and coin — use a cash count sheet for accuracy
- Record the total — this is your actual balance
- Have a second person verify the count (separation of duties)
2. Gather All Receipts & Vouchers
- Collect every receipt, voucher, and slip from the petty cash box
- Total all disbursement receipts — compare to the cash paid out log for your documented spend
- Check that every receipt has a date, amount, description, and who received the cash
- Flag any missing or incomplete receipts
3. Reconcile
- Start with the opening balance (the float at the start of the period)
- Subtract the documented spend (total of all receipts)
- The result should equal the actual cash count
- If there's a discrepancy: investigate before adjusting anything
4. Review Access & Authorization
- Confirm who has access to the petty cash box
- Verify that disbursements were authorized (signed or approved)
- Check that the custodian is not the same person approving disbursements
- Review if any single user has an unusual number of disbursements
5. Document the Audit
- Record the date, auditor name, and cash box audited
- Note the opening balance, receipts total, and cash count
- Record any discrepancies and their suspected cause
- Sign off and file the audit report

- Missing receipts — The #1 finding. Prevention: generate a receipt at the time of every transaction, not after the fact.
- Unsigned disbursements — Cash left the box but nobody's name is on it. Prevention: require a contact/user on every transaction entry.
- Running balance errors — The log says $340 but the box has $280. Prevention: use auto-calculated balances instead of manual formulas.
- No separation of duties — The same person handles cash and approves disbursements. Prevention: use role-based access (admin vs user).
- Infrequent reconciliation — Problems compound when you reconcile monthly instead of weekly. Prevention: run a petty cash reconciliation at least weekly.
Important: SpendNote provides internal cash tracking and receipt generation to support your audit process. It does not replace your accounting software, tax documentation, or formal audit procedures. Use SpendNote records as supporting documentation alongside your official accounting records.
Frequently Asked Questions
How often should petty cash be audited?
At minimum, once per quarter. Many businesses do a quick reconciliation weekly and a full audit monthly. The more people who handle cash, the more frequently you should audit.
What happens if petty cash doesn't balance during an audit?
A discrepancy means either a transaction wasn't recorded, a receipt is missing, or cash was taken without documentation. The first step is to review every transaction since the last balanced audit and identify the gap. With SpendNote, every transaction is timestamped and attributed to a user, so finding the break is much faster than with a paper log.
Who should conduct the petty cash audit?
Ideally, someone other than the petty cash custodian. This separation of duties is a basic internal control. In a small business, the owner or a manager who doesn't normally handle cash is the best choice.
Can SpendNote generate audit-ready reports?
Yes. SpendNote can export filtered transaction reports as branded PDFs — filtered by date range, cash box, or user. These reports include all transaction details, running balances, and are timestamped. They are designed for internal documentation, not as official accounting records.
