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.
Editorial analysis by NHI Mgmt Group, based on content published by Pathlock: “Comprehensive Guide to Accounts Payable Internal Controls”.
Key questions
Q: What breaks when accounts payable controls do not separate approval from payment execution?
A: When AP controls do not separate approval from execution, the same identity can create, validate, and release a transaction.
Q: Why do poor accounts payable controls increase fraud and payment error risk?
A: Poor AP controls increase risk because payment processes depend on independent verification of obligation, amount, and authority.
Q: What are the signs that accounts payable governance is failing?
A: Warning signs include frequent invoice exceptions, duplicate payments, weak audit trails, rushed approvals, and vendor master changes that are not independently validated.
Practitioner guidance
- Separate approval from execution Design AP and payment workflows so the person who prepares a transaction cannot also release it, and ensure exceptions require a different approver.
- Enforce role-based payment access Restrict bank portal and payment system access to explicitly approved roles, and review those roles whenever duties or vendor responsibilities change.
- Make three-way matching mandatory Require purchase order, receiving evidence, and invoice data to align before payment posting, with documented handling for mismatches and disputes.
Bottom line: Accounts payable risk rises when obligation checks, data entry, and payment release are not independently controlled.

Payment governance fails when request, approval, and execution are treated as one workflow. Pathlock’s article shows that AP risk is not primarily about payment speed, but about whether the organisation can prove each step independently. When obligation checking, data entry, and release authority collapse into a single operational path, the control model becomes too weak to distinguish valid payments from manipulated ones. That same governance pattern is the one IAM teams must avoid in privileged and transactional workflows.
A question worth separating out:
Q: How should security teams implement segregation of duties in IAM workflows?
A: Start by mapping the high-risk actions that must never sit in one entitlement path, then enforce those conflicts at role design and provisioning time. Use a conflict matrix, automate checks in your IGA or IAM process, and require independent approval for elevated access. The goal is to block harmful combinations before they reach production.
