What Is Accounts Payable?
Accounts payable is money a business owes suppliers for goods or services already received but not yet paid for.
Why It Matters
Payables are a core piece of liabilities and working capital. They explain how a company can incur costs under accrual accounting while still controlling when cash actually leaves the bank.

Short Explanation
Think of payables as “bills we already owe, cash we have not sent yet.” They are the supplier-side mirror of accounts receivable: timing between economic activity and cash movement.
How Accounts Payable Works
When you receive inventory or services on credit, you typically debit an expense or asset and credit accounts payable. When you pay the supplier, cash falls and payables fall—each step keeps the accounting equation balanced.
The income statement may already reflect the cost; paying the invoice is mainly a balance-sheet and cash flow event. That is why growing payables can temporarily support cash while expenses are already in profit.
Sustainable analysis pairs payables with purchasing volume and payment discipline—stretching suppliers is not a long-term funding strategy.

Frequently Asked Questions
- Is accounts payable the same as debt?
- Not exactly. Payables are short-term amounts owed to suppliers for operating purchases. Bank loans and bonds are different liability categories with their own terms.
- Why would payables grow?
- Often because purchases increased, payment terms lengthened, or the business is timing cash outflows. Compare payables to revenue and purchasing activity for context.
- Does paying payables affect profit?
- Paying a bill is usually a cash and balance-sheet event. The expense was often recorded earlier under accrual rules—so profit and the payment step do not always move together.
