Accounts Payable vs Accounts Receivable: A Worked Month

Accounts receivable is money your customers owe you for work you have already invoiced. Accounts payable is money you owe suppliers for bills you have already received. One is an asset, cash on its way in; the other is a liability, cash on its way out. Both live on the balance sheet, and both exist only when your books run on the accrual method. A cash-basis sole proprietor filing a Schedule C records neither, because they book income when it lands and expenses when they pay. Here is a single month of one small business's books to show exactly what falls into each column.

What accounts receivable and accounts payable mean

Accounts receivable (AR) is the total of invoices you have issued but not yet collected. You did the work or delivered the goods, you sent the bill, and the customer has not paid yet. That unpaid amount is an asset: you have a legal right to the money, so it belongs on your books even though it is not in your bank account.

Accounts payable (AP) is the mirror image. It is the total of bills your suppliers have sent you that you have not yet paid. You received the goods or service, the supplier sent the invoice, and payment is still due. That amount is a liability: you owe it, so it sits on your books as a claim against you.

The words themselves are the memory hook: a receivable is what you will receive, a payable is what you will pay. AR sits on the asset side because money is coming toward you. AP sits on the liability side because money is leaving.

Both are short-term by nature. Standard trade terms run net-15, net-30, or net-60, so most receivables and payables clear within a couple of months. That is why the balance sheet groups them as current assets and current liabilities.

One business's month, in both ledgers

Take Devin, who runs a small commercial-cleaning company as a single-member LLC and keeps the books on the accrual method. Through one month, Devin sends three invoices to clients and receives three bills from suppliers. Nothing has been paid yet at month-end.

The invoices Devin issued become accounts receivable:

The bills Devin received become accounts payable:

At month-end, Devin is owed $6,900 and owes $3,200. The difference, $3,700, is the cash these two ledgers will produce once every invoice is collected and every bill is paid. It is not cash today. The $4,200 office contract will not arrive for another 30 days, the medical office is already late, and the subcontractor wants paying in 10.

This is the gap that catches new business owners. Devin's income statement can show a strong, profitable month while the checking account runs thin, because $6,900 of that profit is parked in receivables and $3,200 of near-term bills is coming due. Profit and cash answer different questions, which is why profit and cash flow can move in opposite directions in the same period.

Accounts payable vs accounts receivable at a glance

Read the table as two halves of the same trade. Every payable your business owes is somebody else's receivable, and every receivable you hold is somebody else's payable. When Devin pays the $1,100 supply bill, Devin's AP drops by $1,100 and the wholesaler's AR drops by the same amount.

Where AR and AP sit, and why cash-basis books skip them

Accounts receivable and accounts payable are balance-sheet accounts, not income-statement accounts. Revenue and expenses hit the income statement when they are earned or incurred; AR and AP track the timing gap between that moment and the cash moving.

They appear on a formal balance sheet. A partnership reports them on Schedule L of Form 1065, and a corporation on Schedule L of Form 1120 or 1120-S, where "Accounts receivable" and "Accounts payable" are named lines. A sole proprietor's Schedule C has no balance sheet at all; it is an income-and-expense statement, so AR and AP do not show up on it directly.

The deeper reason a solo Schedule C filer usually has no AR or AP is the accounting method. The IRS lets most small businesses choose between two:

• Cash method. You report income in the year you actually or constructively receive it, and you deduct expenses in the year you pay them (IRS Publication 334). Nothing is recorded until money moves, so an unpaid invoice and an unpaid bill are not on the books. No AR, no AP.
• Accrual method. You report income in the year you earn it, not the year you are paid, and you deduct expenses in the year you incur them, not the year you pay (Publication 334). The unpaid invoice is booked as revenue and a receivable the day you send it; the unpaid bill is booked as an expense and a payable the day you get it.

Under accrual, the timing is governed by the all-events test: income is counted when all the events that fix your right to it have occurred and you can determine the amount, and an expense is counted when the all-events test is met and economic performance has occurred (IRS Publication 538). That is the machinery that creates a receivable and a payable in the first place.

Which method you may use is mostly a size question. Under Internal Revenue Code section 448(c), a business qualifies as a small business taxpayer, and can use the cash method, if its average annual gross receipts for the three prior tax years are at or below an inflation-adjusted threshold. For tax years beginning in 2026 that threshold is $32 million (Revenue Procedure 2025-32). Nearly every freelancer and small business sits far under it, which is why so many choose cash and keep no AR or AP ledgers. Devin, invoicing on 30-day terms, chose accrual so the books match when the work was done.

Common misconceptions about AR and AP

"Accounts payable is an expense." It is not. The expense is recorded when you incur the bill; accounts payable is the liability that says you have not paid it yet. When Devin later pays the $1,100 supply bill, the entry reduces AP and reduces cash. It does not create a second expense. Treating the payment as a fresh expense double-counts the cost and understates your profit.

"Accounts receivable is cash I can spend." A receivable is revenue you have earned but not collected. It is an asset, not money in the bank. Devin's $6,900 in AR becomes spendable only when clients pay, and the medical office is already late. If a customer never pays, that receivable turns into a bad debt you have to write off, not cash you can count on.

"My cash-basis business has payables and receivables." If you file a Schedule C on the cash method, you record income when you are paid and expenses when you pay, so unpaid invoices and unpaid bills are not in your bookkeeping at all. You might still keep an informal list of who owes you, but there is no AR or AP ledger, and nothing about those unpaid amounts hits your tax return until the cash moves.

How this connects to your books and SparkReceipt

Whether you run on cash or accrual, both ledgers start with a document. Every payable traces to a supplier bill you received, and every receivable traces to an invoice you issued. Keep those documents organized and your accounting software can build the AR and AP aging on top of them. Lose them and the ledgers drift out of reality.

SparkReceipt is the capture layer under that. It records the supplier bills you receive as expenses and the invoices tied to your income in your income records, categorizes each to the right account so they line up with your chart of accounts, and publishes them to QuickBooks Online or Xero, where the actual payable and receivable aging lives. SparkReceipt does not run an AP or AR ledger itself; it keeps the source documents clean and pushes them to the tool that does.

Frequently asked questions

Is accounts payable an asset or a liability? A liability. It is money you owe suppliers for bills you have received but not paid, so it sits on the liability side of the balance sheet as a current liability. Accounts receivable, by contrast, is a current asset.

Is accounts receivable the same as revenue? No. Revenue is income you have earned. Accounts receivable is the portion of that revenue you have earned but not yet collected. Once the customer pays, the amount moves out of receivables and into cash; the revenue was already counted when you invoiced.

Do sole proprietors have accounts payable and receivable? Only if they use the accrual method. A sole proprietor on the cash method, which most Schedule C filers use, records income when paid and expenses when paid, so unpaid invoices and bills never enter the books as AR or AP.

What is the difference between accounts payable and accounts receivable in one sentence? Accounts receivable is money your customers owe you; accounts payable is money you owe your suppliers.

Can a business be profitable and still run out of cash? Yes. If profit is tied up in receivables that customers have not paid while payables come due, the income statement can show a profit the same month the bank balance runs low. That timing gap is exactly what AR and AP measure.

Key takeaways

• Accounts receivable is money customers owe you; accounts payable is money you owe suppliers. AR is a current asset, AP is a current liability, and every payable is someone else's receivable.
• Both live on the balance sheet, not the income statement. They track the gap between when revenue or expense is booked and when cash moves.
• They exist only under the accrual method. A cash-basis Schedule C filer records income when paid and expenses when paid (IRS Pub 334), so has no AR or AP; §448(c) lets a business under the 2026 $32 million gross-receipts threshold choose cash.
• A profitable month can still be cash-short. Devin's $6,900 in receivables and $3,200 in payables net to $3,700 of future cash, not money available today.
• Paying a bill is not a new expense. It reduces accounts payable and cash; the expense was already recorded when the bill was incurred.

Both ledgers are only as accurate as the documents behind them. Capture every supplier bill and every invoice as it happens and your payables and receivables stay grounded in reality instead of guesswork. Get Started with SparkReceipt to keep those documents organized and flowing into your accounting software.
