Accounts Payable: The Complete Procedure Every Business Should Know
Accounts Payable (AP) is one of the most critical financial processes in any organization. It ensures that suppliers are paid accurately and on time while maintaining proper financial control. A well-structured accounts payable procedure not only prevents errors and fraud but also strengthens vendor relationships and improves cash flow management.
In this blog, we’ll walk through the complete accounts payable procedure step by step.
What Is Accounts Payable?
Accounts Payable refers to the money a business owes to suppliers or vendors for goods and services purchased on credit. It is recorded as a liability on the balance sheet until the payment is made.
The Complete Accounts Payable Procedure
Below is the standard end-to-end AP process followed by most businesses:
1. Purchase Requisition
The process begins when a department identifies the need for goods or services. A purchase requisition is created and submitted for approval.
Purpose:
Confirm business need
Prevent unauthorized spending
Maintain budget control
2. Purchase Order (PO) Creation
Once approved, the procurement team issues a Purchase Order (PO) to the vendor. The PO includes:
Description of goods/services
Quantity
Price
Delivery terms
Payment terms
The PO serves as an official agreement between the buyer and supplier.
3. Goods or Services Received
After the vendor delivers the goods or completes the service, the receiving department verifies:
Quantity received
Condition of goods
Compliance with PO specifications
A Goods Received Note (GRN) may be generated as proof of receipt.
4. Invoice Receipt
The vendor sends an invoice requesting payment. The invoice typically includes:
Invoice number
Date
PO reference
Amount due
Payment terms
Invoices can be received via email, post, or accounting software.
5. Three-Way Matching
This is a critical control step in the AP procedure.
The accounts payable team matches:
Purchase Order (PO)
Goods Received Note (GRN)
Vendor Invoice
If all three documents match in terms of quantity, price, and terms, the invoice is approved for payment.
Why it matters:
Prevents overpayment
Detects duplicate invoices
Reduces fraud risk
6. Invoice Approval
After matching, the invoice is routed to authorized personnel for approval. Approval levels may depend on:
Invoice amount
Department budget
Company policy
Proper approval ensures accountability.
7. Recording the Invoice
Once approved, the invoice is recorded in the accounting system:
Debit: Expense or Asset account
Credit: Accounts Payable (liability)
This updates financial records and reflects the outstanding payable.
8. Payment Processing
Payments are scheduled according to agreed payment terms (e.g., 30, 45, or 60 days).
Common payment methods include:
Bank transfer
Cheque
Online payment
Automated clearing systems
Businesses often schedule payments to optimize cash flow while avoiding late fees.
9. Payment Authorization
Before releasing payment, final authorization is obtained to ensure:
The invoice was approved
Payment details are correct
No duplication exists
Segregation of duties is important here to reduce fraud risk.
10. Payment Execution
The payment is processed, and confirmation is sent to the vendor. The transaction is recorded in the accounting system:
Debit: Accounts Payable
Credit: Bank/Cash
The liability is cleared.
11. Record Keeping and Reconciliation
All documents (PO, GRN, invoice, payment proof) are properly stored. Regular reconciliations ensure:
Vendor statements match company records
No outstanding discrepancies
Accurate financial reporting
Best Practices in Accounts Payable
To maintain an efficient AP process, businesses should:
Automate invoice processing
Implement three-way matching
Maintain segregation of duties
Monitor payment deadlines
Regularly reconcile vendor statements
Review aging reports
Automation can significantly reduce manual errors and processing time.

Final Thoughts
Accounts payable is more than just paying bills. It is a structured financial control system that protects a company’s resources while ensuring smooth operations.
