What is an Accounts Payable SOP?
An accounts payable SOP documents the exact steps your team should follow when processing vendor invoices, approving payments, and reconciling accounts. As a specialized standard operating procedure, these procedures form the backbone of the procure-to-pay (P2P) workflow and give finance teams a reliable method for managing what they owe suppliers and service providers.
AP procedures cover everything from the moment an invoice hits your inbox to the final payment and filing. A well-crafted accounts payable SOP defines who can approve payments at different dollar amounts, what documentation needs to be collected, how invoices get matched to purchase orders, and the timing that lets you capture early payment discounts or avoid late fees.
Organizations rely on these documented procedures to reduce fraud risk, catch duplicate payments early, and maintain compliance with both internal controls and external regulations. A proper approval workflow ensures the right people sign off at the right thresholds. When the whole team follows the same process, finance staff spend less time fixing mistakes and more time on work that actually matters.
Key Characteristics of an Accounts Payable SOP
- Invoice Verification Steps: Clear instructions for checking vendor invoices against purchase orders and receiving documents to confirm goods or services were actually delivered.
- Approval Hierarchies: Defined rules about who can approve payments at various dollar levels, along with escalation paths for exceptions and disputes.
- Three-Way Matching: The process for comparing invoices to purchase orders and receiving reports before approving any payment.
- Payment Scheduling: Guidelines for timing payments to meet terms, capture discounts, and maintain healthy cash flow.
- Reconciliation Requirements: Steps for regularly comparing vendor statements against internal records and resolving any discrepancies.
Accounts Payable SOP Examples
Example 1: Small Business Invoice Processing
A regional distribution company creates an AP SOP that requires all invoices to be scanned into their accounting system within 24 hours of arrival. Invoices under $5,000 need one manager signature; anything above that goes to the CFO. The procedure specifies that payments run every Tuesday and Friday, with exceptions documented and approved separately.
Example 2: Enterprise Three-Way Match
A manufacturing company's accounts payable procedures require a three-way match on all purchase order-based invoices. The SOP details how to verify that quantities received match both the PO and the invoice, who handles discrepancies, and the deadline vendors have for submitting invoices after delivery. This catches billing errors and duplicate payments before any money goes out the door.
Accounts Payable SOP vs General Accounting SOP
AP procedures represent a specific subset of broader accounting SOPs, focusing exclusively on outgoing payments.
| Aspect | Accounts Payable SOP | General Accounting SOP |
|---|---|---|
| Scope | Vendor payments and invoice processing | All financial transactions and reporting |
| Focus | Outgoing cash and vendor relationships | Complete financial picture |
| Key Controls | Payment approvals and three-way matching | Journal entries, reconciliations, closing |
| Primary Users | AP clerks and accounts payable managers | All accounting staff |
How Glitter AI Helps with Accounts Payable SOPs
Glitter AI simplifies documenting complex AP procedures. Finance teams can record their actual invoice processing workflow, and Glitter automatically generates step-by-step procedures complete with screenshots of every click and action. This captures the software-specific details that written instructions often miss.
When AP processes change (new approval thresholds, software updates, revised controls), teams can refresh their documentation simply by recording the new workflow. The result is AP procedures that reflect what people actually do today, helping new hires ramp up faster with less hand-holding.
Frequently Asked Questions
What is an accounts payable SOP?
An accounts payable SOP is a documented set of procedures that standardizes how an organization processes vendor invoices, approves payments, reconciles accounts, and maintains financial records. It ensures consistency and compliance when handling money owed to suppliers.
What should be included in accounts payable procedures?
AP procedures should cover invoice receipt and verification steps, three-way matching requirements, approval hierarchies with dollar thresholds, payment scheduling guidelines, vendor setup protocols, exception handling, and account reconciliation processes.
Why are accounts payable SOPs important for compliance?
Accounts payable SOPs establish internal controls that prevent fraud, catch errors, ensure proper segregation of duties, and create audit trails. These documented procedures demonstrate to auditors that the organization follows consistent processes for managing vendor payments.
How often should AP procedures be reviewed and updated?
Most organizations review their accounts payable procedures every six to twelve months, or whenever significant changes occur to accounting software, approval thresholds, regulatory requirements, or company policies. Regular updates keep procedures aligned with actual practice.
What is three-way matching in accounts payable?
Three-way matching is a verification process where an invoice is compared against both the purchase order and the receiving report before payment is approved. This confirms the company only pays for goods or services that were actually ordered and received.
Who is responsible for creating accounts payable SOPs?
Typically the accounts payable manager or controller creates AP procedures, often with input from the CFO and internal audit team. Staff who handle AP tasks daily should review procedures to verify they reflect actual workflows.
How do AP procedures help prevent fraud?
AP procedures establish segregation of duties, approval thresholds, vendor verification requirements, and three-way matching. These controls make it difficult for any single person to create fictitious vendors, process unauthorized payments, or manipulate financial records.
What is the difference between AP policies and AP procedures?
AP policies state the rules and principles governing accounts payable, such as requiring approval for all payments above a certain amount. AP procedures are the step-by-step instructions for implementing those policies, detailing exactly how to process invoices and obtain approvals.
How can automation improve accounts payable procedures?
AP automation streamlines invoice capture, matching, approval routing, and payment processing. Combined with documented procedures, automation reduces manual errors, accelerates cycle times, and frees AP staff to focus on exceptions and vendor relationships.
What metrics should be tracked in accounts payable?
Key AP metrics include days payable outstanding, invoice processing time, cost per invoice, percentage of invoices with exceptions, early payment discount capture rate, and duplicate payment rate. Tracking these reveals opportunities to improve AP procedures.
