Whether you inherited a dusty policy from a former controller or are drafting one from scratch, a well‑crafted accounts payable (AP) policy is essential for any organization that wants to protect its cash flow and avoid costly audit findings. The policy should reflect how the team actually works, not an outdated document that no one reads.

Seven Core Questions Every AP Policy Must Answer

Brex’s guide recommends that an AP policy address the following topics:

• Who may submit invoices and how?
• What information must accompany each invoice?
• How are invoices coded and routed for approval?
• What are the approval thresholds and who signs off at each level?
• When are payments scheduled and how are they executed?
• What controls prevent duplicate or fraudulent payments?
• Who is responsible for maintaining and updating the policy?

Leaving any of these unanswered forces staff to make ad‑hoc decisions, leading to drift between the written rule and daily practice.

Separate Policy, Procedure and Control

Think of the policy as a speed limit sign: it states the rule. The procedure (often a standard operating procedure or run‑book) explains step‑by‑step how to obey that rule. Controls are the automated checks—such as ERP validation or AP‑tool settings—that catch violations even when a person forgets the rule.

Keeping these layers distinct makes enforcement easier. For example, a policy may require dual approval for payments over $5,000. The procedure details the exact screens to click, while the ERP can be configured to block any payment that lacks the second approval.

Common Signs of a Failing Policy

When a policy does not match reality, finance teams experience predictable problems:

• Chasing signatures at month‑end: Without written intake and coding rules, staff spend valuable time locating approvers and reconciling discrepancies.
• Undetected vendor changes and duplicate payments: A lack of documented verification steps allows banking details to be altered via email and duplicate invoices to slip through.
• Audit mismatches: Auditors compare the policy to actual transactions. Gaps turn a routine test into a time‑consuming fieldwork exercise.
• Inconsistent approval thresholds: Different managers apply their own informal limits, creating ambiguity and potential risk.
• Unreliable cash‑flow metrics: Varying invoice intake timing skews days payable outstanding and accrual calculations.

Building a Policy That Sticks

To avoid these pitfalls, follow these practical steps:

1. Align with current tools: Reference the exact ERP or AP automation platform (e.g., NetSuite, SAP) so the policy can be enforced by system controls.
2. Define clear approval matrices: List dollar thresholds and the required approvers for each level.
3. Document vendor verification: Require a call‑back or second approver for any new vendor or banking detail change.
4. Include exception handling: Outline how urgent payments or invoices from new vendors are processed.
5. Assign a policy owner: Designate a single individual—often the controller or finance manager—to maintain, update and resolve ambiguities.
6. Scale to company size: Even a solo AP operator can use the same core rules, simply adjusting the number of approvers and review steps.

When the policy mirrors the actual workflow, it becomes a living document rather than a relic.

Why It Matters for Your Business

A solid AP policy protects the bottom line by reducing fraud risk, improving cash‑flow forecasting and streamlining audit preparation. The 2026 Association for Finance Professionals Payments Fraud and Control Survey found that 76 % of organizations reported attempted or actual payment fraud in 2025. Robust controls—documented in the policy—are the first line of defense.

Moreover, consistent processes free finance leaders to focus on strategic initiatives instead of firefighting month‑end bottlenecks. By establishing clear responsibilities, approval thresholds and automated safeguards, businesses of any size can ensure that their accounts payable function supports growth rather than hinders it.
