ap processing Definition
Accounts payable (AP) processing is the process of validating, recording, and paying invoices from suppliers. The AP process typically begins when a supplier sends an invoice to a company. The invoice is then reviewed by the AP department to ensure that it is accurate and has been approved for payment. Once the invoice has been approved, it is recorded in the accounting system and a payment is scheduled. The AP department then pays the invoice either by check or electronically.
