Why Conduct an Accounts Payable Audit?

Before we get to the template, let's understand why an accounts payable audit is so important. It's more than just checking invoices. It's about:

• Fraud Prevention: Detecting and preventing fraudulent payments, such as fictitious vendors or inflated invoices.
• Control Effectiveness: Evaluating the effectiveness of your AP controls in preventing errors and unauthorized transactions.
• Compliance: Ensuring compliance with relevant regulations and internal policies.
• Efficiency Improvement: Identifying opportunities to streamline the AP process and reduce costs.
• Accuracy of Financial Reporting: Verifying the accuracy and completeness of accounts payable balances on your financial statements.

The IRS emphasizes the importance of accurate record-keeping for businesses. Proper AP controls contribute directly to this accuracy and can help avoid potential issues during an audit. (See IRS.gov Record Keeping)

Key Areas to Cover in Your Accounts Payable Audit

A thorough auditing accounts payable process should cover several key areas. Here's a breakdown:

1. Vendor Master File

• Verification of Existence: Confirm that all vendors in your system are legitimate and authorized.
• Segregation of Duties: Ensure that the same person doesn't have complete control over vendor creation, approval, and payment.
• Duplicate Vendor Records: Identify and eliminate any duplicate vendor records, which can lead to errors and potential fraud.
• Review of Vendor Addresses: Cross-reference vendor addresses with public databases to identify any suspicious activity.

2. Invoice Processing

• Proper Authorization: Verify that all invoices are properly authorized before payment.
• Matching of Purchase Orders (POs) and Receiving Reports: Ensure that invoices are matched to valid POs and receiving reports (the "three-way match"). This is a critical accounts payable testing procedure.
• Invoice Coding Accuracy: Confirm that invoices are coded to the correct general ledger accounts.
• Review of Supporting Documentation: Examine supporting documentation, such as contracts and agreements, to verify the accuracy of invoice amounts.

3. Payment Processing

• Payment Authorization: Verify that all payments are properly authorized.
• Check/ACH Security: Ensure that checks are stored securely and that ACH payments are properly authorized and monitored.
• Voided Check Review: Investigate any voided checks to determine the reason for the void and ensure that the payment was not made elsewhere.
• Reconciliation of Bank Statements: Regularly reconcile bank statements to identify any discrepancies.

4. Discounts and Terms

• Discount Utilization: Verify that the company is taking advantage of all available discounts.
• Terms Compliance: Ensure that payments are made within the agreed-upon terms.
