Accounts Payable Audit

by Admin on Sep 05, 2025 in Accounts Payable Audits

An accounts payable audit verifies the accuracy, validity, and completeness of a company's outgoing payments to suppliers and vendors.

Let's break it down clearly and plainly:

"An accounts payable audit verifies the accuracy, validity, and completeness of a company's outgoing payments to suppliers and vendors."

Here's what each part means:

  • Accounts payable (AP): This refers to the money your company owes to suppliers or service providers - basically, your unpaid bills.

  • Audit: This is a systematic review or examination - in this case, of the accounts payable records.

  • Verifies the accuracy: Checks that the amounts you're paying match the actual invoices. No overpayments, underpayments, or typos.

  • Verifies the validity: Makes sure the invoices are real, approved, and not duplicated or fraudulent.

  • Verifies the completeness: Ensures that all invoices are accounted for - no missing records or forgotten liabilities.

Why is it important?

An AP audit helps prevent fraud, spot errors, uncover duplicate payments, and make sure you're not paying for things you didn't actually receive. It's about financial control and protecting your cash.

When is an Accounts Payable Audit Advisable?

An accounts payable audit is advisable whenever there's a risk of financial loss, compliance failure, or operational inefficiency. Here's a breakdown of specific situations when it's a smart move:

When to Conduct an Accounts Payable Audit

1. Before a Major Financial Event

  • Mergers, acquisitions, or investment rounds require clean books.
  • Buyers and investors want proof that liabilities are accurate and no hidden obligations exist.

2. After a Change in Staff or Systems

  • New finance teams or recent changes in ERP/accounting software can lead to configuration errors or oversight.
  • It's wise to check that workflows, approvals, and vendor setups are correct.

3. If Fraud or Irregularities Are Suspected

  • Duplicate payments, unapproved vendors, or strange invoice patterns may signal internal fraud or errors.
  • An audit helps surface these red flags.

4. During Year-End Close or Financial Reporting

  • Ensures liabilities are accurately recorded in monthly, quarterly, or annual financial statements.
  • Auditors often request this as part of their assurance process.

5. When Cash Flow Is Tighter Than Expected

  • An AP audit can help find leaks in cash-like early payments, overpayments, or unused credits.

6. Periodically as Part of Internal Controls

  • Many companies do quarterly or annual AP audits as a best practice to:

    • Catch small errors before they grow.
    • Maintain SOX compliance or ISO certification.
    • Keep staff accountable and processes sharp.

In Short:

An AP audit is advisable whenever you want to tighten control, reduce risk, or ensure that every penny spent is valid and justified.
