Accounts Payable (AP)
Definition
Accounts payable (AP) represents the money a company owes to its suppliers, vendors, and service providers for goods or services received but not yet paid for. AP is recorded as a current liability on the balance sheet and must be managed carefully to maintain vendor relationships and optimize cash flow timing.
Overview
Accounts payable is the mirror image of accounts receivable: it represents amounts you owe to others rather than amounts owed to you. Common sources include vendor invoices, contractor payments, software subscriptions billed in arrears, and rent.
From a cash flow management perspective, AP can be a strategic tool. Paying vendors on the latest acceptable terms (without damaging relationships) keeps cash in the business longer. This approach, combined with collecting receivables quickly, improves working capital and extends effective runway.
However, letting AP grow too large relative to cash reserves creates risk. If multiple large invoices come due simultaneously, the cash outflow can create a short-term liquidity crunch. Maintaining a clear AP aging schedule, categorizing payables by due date, helps founders anticipate and manage these cash flow peaks.
Example
A startup receives a $12K invoice from a cloud provider with net-45 terms. The $12K is recorded as accounts payable and remains a liability until the bill is paid.
