Accounts Payable Explained: What It Is and How to Manage It
Accounts payable is the amount a business owes to suppliers for goods and services received but not yet paid for. This guide explains what accounts payable is, how the AP process works, and how to manage it effectively.
What Is Accounts Payable?
Accounts payable (AP) is the total amount a business owes to its suppliers and vendors for goods or services it has received but not yet paid for. It appears as a current liability on the balance sheet. When a supplier sends an invoice and the business has not yet paid it, that outstanding balance is accounts payable.
How the AP Process Works
The standard accounts payable process: a purchase order is raised and goods or services are received; the supplier invoice arrives and is matched against the purchase order and delivery note (the three-way match); the invoice is approved, coded to the correct general ledger account, and posted; payment is made on or before the due date. In larger organisations, this process involves AP clerks, procurement teams, and a finance approval workflow.
Key Accounts Payable Metrics
Days Payable Outstanding (DPO) = (Accounts Payable / COGS) x 365. DPO measures how long the business takes to pay its suppliers. A higher DPO means the business holds on to cash for longer — beneficial for cash flow but potentially harmful to supplier relationships if pushed too far. AP turnover ratio = COGS / Average Accounts Payable. A higher ratio indicates faster payment cycles.
AP and Cash Flow Management
Accounts payable is a significant lever in working capital management. Extending payment terms with suppliers (increasing DPO) improves short-term cash flow. Early payment discounts — where suppliers offer 1-2% off for payment within 10 days — can offer attractive effective annual returns where cash is available. These trade-offs are core topics in ACCA FM (Financial Management).
AP Automation
Modern AP teams use automation to reduce manual invoice processing. OCR (optical character recognition) extracts invoice data automatically. Three-way matching is done by software rather than manually. Approval workflows are managed digitally. Tools such as Xero, QuickBooks, and dedicated AP platforms like Tipalti and Basware handle this for businesses of different sizes.
