What Is Accounts Payable? Definition, Process, and Examples

Accounts payable in plain terms

When a business buys from a vendor on credit — say, $5,000 of inventory due in 30 days — it doesn't pay immediately. Until it does, that $5,000 is an account payable: a promise to pay recorded as a liability. When the bill is paid, AP goes down and cash goes down with it.

AP is the mirror image of accounts receivable: receivables are what customers owe you (an asset), payables are what you owe suppliers (a liability).

Accounts payable on the balance sheet

AP sits under current liabilities because it's due within a year (usually much sooner). It matters for two reasons:

• Liquidity: large or fast-growing AP relative to cash can signal a business stretched thin — or one using supplier credit smartly to fund operations.
• Working capital: how long you take to pay (see days payable outstanding) directly affects how much cash stays in the business.

The accounts payable process

AP isn't just a number — it's a workflow that repeats for every invoice:

Step	What happens
1. Receive	An invoice arrives by email, mail, or portal
2. Capture & code	Vendor, amount, dates, and line items are recorded and coded to the right GL account
3. Match	The invoice is checked against the purchase order and/or goods receipt (two- or three-way matching)
4. Approve	The bill is routed to the right approver(s)
5. Pay	Payment is issued per terms
6. Record	The transaction is booked and reconciled

Done manually, steps 2–4 are where time and errors pile up — keying invoice data by hand, chasing approvals, catching duplicates. For a deeper walkthrough, see the accounts payable process guide.

Examples of accounts payable

• A restaurant owes its food distributor $8,000 for last week's delivery, due in 30 days.
• A software company owes a contractor $12,000 for completed work, net-45.
• A retailer owes a wholesaler for inventory received but not yet paid.

What's not AP: payroll (a separate liability), long-term loans (long-term debt), and anything already paid.

Automating accounts payable

As invoice volume grows, the manual AP cycle becomes the bottleneck. Accounts payable automation software captures each invoice, extracts and codes the data, runs two- and three-way matching, and routes approvals automatically — then pushes the approved bill into QuickBooks, Xero, or another system. (It handles the capture-to-approval workflow; it doesn't issue cards or pay vendors itself.) The result is the same AP, processed in minutes instead of hours and with far fewer errors.

The bottom line

Accounts payable is what your business owes suppliers for credit purchases — a current liability and a core part of managing cash. Understanding AP means understanding both the number on the balance sheet and the process behind it. As that process scales, moving it from inboxes and spreadsheets into a structured AP workflow is what keeps it accurate and on time.
