What Is Accounts Payable (AP)?
Accounts payable (AP) is the money a business owes to its suppliers and vendors for goods or services it has received but not yet paid for. It sits as a current liability on the balance sheet and represents short-term obligations, typically due within 30 to 90 days of the invoice date.
What accounts payable is and why it matters
Accounts payable is the counterpart to accounts receivable: it tracks what you owe rather than what you're owed. Every time a business buys on credit — inventory, software, professional services — the amount lands in AP until the bill is settled. Managing it well is a cash-flow discipline: pay too early and you give up working capital; pay too late and you damage supplier relationships or miss early-payment discounts. For an accounting firm, AP is a recurring client deliverable — capturing bills, coding them to the right expense account, routing approvals, and scheduling payment — and it's one of the most repetitive, error-prone parts of the monthly cycle.
A worked example
A design agency receives a $4,500 invoice from a printing vendor on March 3, with Net 30 terms. On receipt, the bookkeeper records a journal entry: debit *Printing Expense* $4,500, credit *Accounts Payable* $4,500. The $4,500 now shows as a liability. On March 31, the agency pays the bill: debit *Accounts Payable* $4,500, credit *Cash* $4,500. The liability clears, and cash drops by the same amount. At any month-end, the total of all such unpaid bills is the company's accounts payable balance.
How firms handle it today
Most firms run AP from a mix of email inboxes, PDF bills, and a bookkeeping tool — manually keying each invoice, coding the expense, chasing an approver, and matching payments back to bills at reconciliation. The volume is high and the judgment per item is low, which is exactly why it eats hours.
How OCTA Flow relates to accounts payable
OCTA Flow runs the mechanical AP steps for you: it captures bills, proposes the expense coding, routes approvals, and logs every action to an audit trail — your team reviews the exceptions and signs off. That turns AP from line-by-line data entry into a review task.
