Accounts payable controls: what IAM teams can learn from payment governance

TL;DR: Accounts payable internal controls are presented as a layered system for preventing fraud, duplicate payments, and approval failures through segregation of duties, invoice matching, access controls, and audit trails, according to Pathlock. The same governance logic applies across identity programmes: when authority, verification, and execution are not separated, risk becomes operational rather than theoretical.

NHIMG editorial — based on content published by Pathlock: internal controls in accounts payable and financial governance

By the numbers:

• Over 82% of organizations have faced fraud attempts in recent years.
• 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation.
• 96% of organizations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.

Questions worth separating out

Q: How should organizations separate approval and execution in accounts payable workflows?

A: Organizations should ensure that no one role can initiate, approve, and release the same payment.

Q: Why do duplicate payments happen when AP controls are weak?

A: Duplicate payments usually occur when invoice matching, exception handling, and posting controls are fragmented or manual.

Q: What do security teams get wrong about audit trails in financial workflows?

A: Teams often treat logs as reporting output instead of a core control.

Practitioner guidance

• Separate initiation, approval, and execution rights Map every payment and access workflow so no single role can create, approve, and release the same transaction.
• Require evidence before authorisation Use purchase orders, receipts, invoice validation, and change confirmation as mandatory proof points before payment release.
• Strengthen vendor change verification Verify bank detail changes or payee updates using a pre-existing trusted contact method rather than the request itself.
