Accounts Payable vs Accounts Receivable: What's the Difference?

Accounts payable (AP) is money your business owes to suppliers for goods or services you have received but not yet paid for; accounts receivable (AR) is money customers owe you for goods or services you have delivered but not yet been paid for. AP is a liability on your balance sheet and AR is an asset. Both exist only because you trade on credit — buy now, pay later on one side; sell now, collect later on the other.

Accounts payable vs accounts receivable at a glance

• Direction of money — AP: cash will flow out to suppliers. AR: cash will flow in from customers.
• Balance sheet — AP: a current liability. AR: a current asset.
• Source document — AP: a supplier's bill or invoice you receive. AR: a sales invoice you issue.
• What creates it — AP: a purchase on credit terms. AR: a sale on credit terms.
• Normal balance — AP: credit. AR: debit.
• Main report — AP: payables aging (what you owe and when it falls due). AR: receivables aging (what you are owed and how overdue it is).
• Main risk — AP: paying the wrong amount, twice, or late, and damaging supplier relationships. AR: customers paying late or never.
• Key metric — AP: days payable outstanding (how long you take to pay). AR: days sales outstanding (how long customers take to pay you).

One useful way to remember it: the same invoice sits on both sides. When you buy from a supplier on credit, the bill is in your AP and in the supplier's AR at the same time.

How each one is recorded

Accounts payable entries

When a supplier's bill arrives for something you have received, you record the cost and the amount owed:

• Debit the expense or asset (for example, Inventory, Rent, Repairs).
• Credit Accounts payable.

When you pay it, the liability goes away and so does the cash:

• Debit Accounts payable.
• Credit Bank.

Accounts receivable entries

When you issue a sales invoice, you record revenue and the amount owed to you:

• Debit Accounts receivable.
• Credit Sales.

When the customer pays:

• Debit Bank.
• Credit Accounts receivable.

Notice that neither payment touches the profit and loss. The expense was recognised when the bill was recorded and the revenue when the invoice was issued; paying and collecting only move balances between cash and AP or AR. That is accrual accounting doing its job.

Worked example: a coffee roaster with both sides moving

A hypothetical small-batch coffee roaster in Bristol buys green coffee from an importer and sells roasted beans wholesale to cafés. To keep the arithmetic clear, VAT is left out.

1. 1 March — buying on credit. The roaster receives 600 kg of green coffee at £7.20 per kg: £4,320, on 30-day terms. Debit Inventory £4,320, credit Accounts payable £4,320. AP is now £4,320.
2. 8 March — selling on credit. After roasting, it invoices a three-site café group £2,900 on 14-day terms. Debit Accounts receivable £2,900, credit Sales £2,900. AR is now £2,900.
3. 22 March — the café group pays on time. Debit Bank £2,900, credit Accounts receivable £2,900. AR is back to zero.
4. 31 March — paying the importer. Debit Accounts payable £4,320, credit Bank £4,320. AP is back to zero.

Because customers pay in 14 days and the supplier gives 30, the roaster collected before it had to pay. Now change one fact: the café group pays on 22 April instead, a full month after the due date. On 31 March the roaster still owes £4,320 but has collected nothing, so it has to find that cash from its own reserves. Its profit for March is identical in both versions. Only the timing of AR collection changed, and with it the cash position.

At a month-end balance sheet in the late-payment version, the roaster would show AR of £2,900 under current assets and zero AP (having paid the importer), and its bank balance would be £2,900 lower than in the on-time version. That gap is exactly why owners watch AR and AP together rather than separately.

How the two processes differ day to day

Running accounts receivable

• Agree credit terms before you deliver, and put them on every invoice.
• Invoice promptly — the payment clock starts when the customer has the invoice.
• Send reminders before and after the due date, and statements showing everything outstanding.
• Match incoming payments to the right invoices, including part-payments.
• Review the receivables aging weekly and decide when to pause supply or escalate.

Running accounts payable

• Check each bill against what was ordered and received before approving it.
• Route bills for approval by someone with authority to commit the spend.
• Schedule payment for the due date — not earlier unless there is a discount worth taking, not later.
• Verify any change to a supplier's bank details through a known phone number before paying.
• Reconcile supplier statements to your own AP ledger monthly.

Where AP and AR get confused

• Customer advances are not receivables. If a customer pays a deposit before you deliver, you owe them goods or a refund. That is a liability (customer advance or deferred revenue), not AR.
• Supplier prepayments are not payables. If you pay a supplier upfront, they owe you the goods. That is an asset (prepayment), not a negative AP balance.
• Customers who are also suppliers. If you buy from and sell to the same company, keep the AP and AR separate. Offset them only when both sides have agreed, and record the offset as its own entry.
• Cash-basis habits. Recording a bill only when you pay it means your AP is always zero and your profit and loss is wrong in every month where bills and payments fall in different periods.
• Credit notes. A credit note from a supplier reduces AP; a credit note you issue reduces AR. Apply each one to the invoice it relates to so the aging stays accurate.

Reading AR and AP together

Both balances are part of working capital. A healthy pattern for many small businesses is AR that turns into cash at least as fast as AP falls due. If receivables are growing faster than sales, customers are paying more slowly. If payables are rising while purchases are flat, you are paying suppliers later — sometimes on purpose, sometimes because cash is tight. Compare each to your own terms and your own history rather than a generic benchmark.

For receivables, HelloBooks lets you send unlimited invoices with payment links (Stripe, Razorpay or PayPal), send automated overdue reminders, issue customer statements with aging, and record customer advances and credit notes properly. For payables, it records bills with approval workflows, schedules payment for the due date, supports purchase orders, goods receipt notes and 3-way matching, and handles vendor prepayments, debit notes and vendor statements. Find & match pairs bank lines with the invoices and bills they settle, and the AR and AP aging reports, balance sheet and cash flow statement show both sides of working capital in one place.
