Restaurant POS Audit: 20 Things Every Owner Should Check
Your restaurant’s POS is more than a cash register. It controls—or influences—
sales reporting, payment processing, discounts, refunds, tips, employee permissions,
cash handling and the financial information that ultimately reaches your accounting system.
That makes the POS one of the most important financial-control systems in the restaurant.
A POS can be configured incorrectly for months without anyone noticing.
Customers still pay. Employees still clock in. Sales still appear on reports.
But small configuration and control problems can create inaccurate reporting,
unexplained differences, unnecessary discounts, missing deposits, accounting
problems and financial leakage.
A restaurant POS audit asks whether the system is accurately recording what
you sold, how customers paid, who handled the transaction and where the money went.
1. Sales Reporting
Start with the most basic question:
Review daily, weekly and monthly sales against:
- Bank deposits
- Previous periods
- Guest counts
- Labor
- Inventory usage
- Business hours
Look for unusual fluctuations, unexplained changes or numbers that don’t fit
what was actually happening operationally.
Your POS sales report should increase confidence in your revenue numbers—not create more questions.
2. Payment Types
Review every payment method configured in the POS.
- Cash
- Credit cards
- Debit cards
- Gift cards
- House accounts
- Other tender types
Make sure each payment type is being recorded and accounted for correctly.
A tender that is configured or mapped incorrectly can create problems all
the way through your bank reconciliation and financial statements.
3. Credit-Card Settlements
Your POS sales total is not necessarily the amount that should appear in the bank.
Credit-card processing can involve:
- Processing fees
- Tips
- Refunds
- Chargebacks
- Adjustments
- Settlement timing
Every settlement should ultimately be traceable to the corresponding bank activity.
Settlement reconciliation is one of the most important checks in a restaurant POS audit.
4. POS-to-Bank Reconciliation
The question is not:
“Does today’s deposit look about right?”
The question is:
Can we explain the difference between POS activity and the money that reached the bank?
A proper reconciliation accounts for settlement timing, tips, refunds,
processing activity and other legitimate differences.
Unexplained differences deserve investigation.

5. Discounts
Review who can apply discounts and how frequently discounts are being used.
- Employee discounts
- Manager discounts
- Promotional discounts
- Manual discounts
- Percentage discounts
- Dollar discounts
Review discount dollars as well as frequency.
Unusual discount activity may point to a training issue, pricing problem,
promotion problem or control weakness.
6. Voids
Voids deserve separate review.
Look at:
- Who is voiding transactions
- How often voids occur
- What is being voided
- When the void occurs
- Whether management approval is required
A void is not automatically suspicious. Repeated unexplained patterns are what deserve investigation.
7. Refunds
Refunds should be monitored separately from voids.
- Frequency
- Dollar amount
- Employee
- Manager approval
- Reason
- Timing
Management should be able to determine why money was returned to a customer.
8. Comps
Complimentary items and checks should have a defined purpose and documented reason.
Review:
- Who can issue comps
- Available comp reasons
- Frequency
- Dollar value
- Employee or manager activity
If the restaurant cannot explain its comp activity, it has a control problem.
9. Open Checks
Open checks can create both operational and accounting problems.
- How many remain open
- How long they remain open
- Who opened them
- Whether old checks are being properly closed
- Whether employees are using open checks to delay transactions
A daily review of unusual open checks prevents old transaction problems from accumulating.
10. Tips
Tips should be tracked from the moment they are entered until they are paid
and recorded.
- Credit-card tips
- Cash tips
- Tip payouts
- Tip pooling
- Tip allocations
- Payroll reporting
- Accounting entries
The restaurant should be able to explain that entire flow.

11. Employee Permissions
Every employee should not have access to every POS function.
Review who can:
- Void transactions
- Issue refunds
- Apply discounts
- Issue comps
- Reopen checks
- Change prices
- Access reports
- Modify settings
- Perform cash functions
Employees should have only the permissions necessary to perform their job.

12. Manager Overrides
Manager overrides should be reviewed periodically.
If managers are constantly overriding transactions, determine why.
The issue could be:
- Poor POS configuration
- Poor employee training
- Incorrect menu setup
- Weak controls
- Normal operational exceptions
Don’t just count overrides. Look for the operational pattern causing them.
13. Menu Pricing
Verify that the prices configured in the POS match what customers should
actually be charged.
Review:
- Food pricing
- Beverage pricing
- Modifiers
- Add-ons
- Specials
- Happy-hour pricing
- Online ordering
- Third-party ordering
Small Pricing Errors Become Large Numbers
A menu item underpriced by only $1 and sold
1,000 times per month costs approximately
$12,000 per year in potential revenue.

.
14. Menu Items and Modifiers
Review whether items and modifiers are configured correctly.
Incorrect setup can affect:
- Sales reporting
- Inventory
- Recipe costing
- Discounts
- Taxes
- Kitchen production
- Financial reporting
Clean financial reporting begins with a clean POS menu structure.
15. Sales Tax
Verify that taxable and non-taxable items are configured appropriately.
- Tax rates
- Tax categories
- Exempt items
- Discount treatment
- Refund treatment
- Reporting
Why This Matters
Sales-tax configuration deserves special attention because errors can create
reporting and compliance exposure.
16. Gift Cards
If the restaurant sells gift cards, review:
- Gift-card sales
- Redemptions
- Outstanding balances
- Refunds
- Expiration policies
- Accounting treatment
Gift cards generally represent an obligation to the customer—not simply
ordinary restaurant revenue when the card is sold.
17. Cash Drawer Controls
Review the complete cash process.
Starting Cash → Cash Sales → Payouts → Expected Cash → Actual Cash → Deposit
Look for recurring shortages or overages.
Small cash discrepancies repeated over hundreds of shifts can become meaningful annual losses.

restaurant cash handling procedures
.
18. User Activity
Your POS contains valuable information about employee and manager transaction activity.
Review reports for patterns such as:
- Excessive voids
- Unusual refunds
- Frequent discounts
- Reopened checks
- Unusual cash activity
- Activity outside normal working hours
The goal is not to assume wrongdoing.
The goal is to identify transaction activity that deserves an explanation.
19. Accounting Integration
If your POS connects to QuickBooks or another accounting platform, verify
that the integration is actually working as intended.
Review how the system maps:
- Sales
- Payment types
- Discounts
- Refunds
- Sales tax
- Tips
- Processing fees
- Clearing accounts
A POS integration can technically be connected while still producing inaccurate accounting.

20. Daily Close and Reconciliation Procedures
Finally, determine whether the restaurant has a repeatable daily close process.
A good process establishes:
- Who closes the shift
- What reports are reviewed
- What gets reconciled
- Who investigates discrepancies
- Where documentation is stored
The best POS configuration in the world will not protect the restaurant
if nobody reviews the information it produces.
What Should Happen After a POS Audit?
Finding problems is only half the job.
For every significant finding, management should know:
What Is Wrong?
State the specific configuration, control or reconciliation problem.
Why Does It Matter?
Explain the financial or operational risk.
How Much Could It Cost?
Quantify the exposure where the records make that reasonably possible.
Who Is Responsible for Fixing It?
Assign ownership instead of leaving corrective action undefined.
What Should Happen Next?
Define the corrective action and how the result will be verified.
That’s the difference between reviewing a POS and performing a financial-systems audit.
Your POS Is Only One Part of the System
A POS audit can uncover important problems, but the POS does not operate in isolation.
Customer → POS → Payment Processor → Bank → Accounting → Financial Statements
Alongside that flow are:
Payroll → Inventory → Purchasing → Cash → Tips → Management Controls
A problem anywhere along those chains can affect the final numbers management relies on.
That’s why a true financial-systems review goes beyond the POS itself.
When Should You Have Your Restaurant POS Audited?
Consider a POS audit if:
- Your sales don’t seem to match your deposits
- Toast and QuickBooks don’t agree
- You have unexplained cash shortages
- Discounts or voids seem unusually high
- Your food or beverage costs don’t make sense
- You don’t trust your P&L
- Employees have more POS access than they should
- Your restaurant recently changed POS systems
- You acquired an existing restaurant
- Your accounting integration recently changed
- You simply are not confident that the numbers are accurate
The best time to find a control problem is before it becomes an expensive one.
What Your POS Should Ultimately Tell You
At minimum, your POS should allow management to confidently answer:
What Did We Sell?
Reliable sales by item, category, day and period.
How Did Customers Pay?
Cash, cards, gift cards and other tenders.
Who Handled the Transactions?
Employee and manager accountability.
What Should Have Reached the Bank?
Traceable settlement and deposit expectations.
What Should Have Reached Accounting?
Correctly mapped revenue, taxes, tips, cash and liabilities.
If you cannot confidently answer those questions, don’t guess. Audit the system.
