Accounts payable (AP) are bills to be paid as part of the normal course of business.
This is a standard accounting term, one of the most common liabilities, which normally appears in the balance sheet listing of liabilities. Businesses receive goods or services from a vendor, receive an invoice, and until that invoice is paid the amount is recorded as part of “accounts payable.”
