Accounts Receivable

Accounts receivable is the total amount customers owe a business for goods or services already delivered but not yet paid for. It sits on the balance sheet as a current asset, money the business has earned and is entitled to collect, but has not yet received in cash.

Accounts receivable does not have a single formula, but two calculations are consistently useful for managing it.

Closing accounts receivable balance:

Accounts Receivable = Opening Balance + Invoices Issued - Payments Received - Credit Notes

• This is the running balance: what was owed at the start of the period, plus new invoices raised, minus payments collected and any credits issued. The closing balance is what appears on the balance sheet.

Accounts receivable turnover:

AR Turnover = Revenue / Average Accounts Receivable

This measures how many times receivables are collected and replaced over a period. A higher number means faster collection. Its inverse, divided into the number of days in the period, gives Days Sales Outstanding (DSO), which expresses the same information as an average number of days to collect.

Both figures matter, but for day-to-day cash management the aging report is the most practical tool: it shows the receivables balance broken down by how long each invoice has been outstanding, which makes overdue amounts visible and actionable.

A mid-sized architecture firm closes its books at the end of Q3. At the start of the quarter, accounts receivable stood at $94,000. During the quarter, the firm issued $310,000 in invoices and collected $278,000 in payments. One client was issued a $4,000 credit note for a disputed fee.

Closing AR Balance:

$94,000 + $310,000 - $278,000 - $4,000 = $122,000

The receivables balance has grown from $94,000 to $122,000. That growth is not automatically a problem, if revenue grew over the quarter, a larger receivables balance is expected. The question is whether the growth reflects more invoicing or slower collection.

The aging breakdown tells the real story:

Most of the balance is current. The $19,000 in the 61-day-plus buckets is worth attention, that is where collection risk starts to build. The $7,000 over 90 days should already be in active follow-up, and if the firm's standard terms are net 30, it is more than three months late.

It represents earned revenue that has not yet converted to cash

Every dollar in accounts receivable is a dollar the business has already worked for, invoiced, and is entitled to. The gap between invoicing and collection is not a financial loss, but it is a cash timing problem. The business has incurred the costs of delivery (labor, materials, overhead) and recorded the revenue, but the cash has not arrived. Until it does, the receivables balance is carrying a real economic value that cannot be spent.

Growing receivables can signal a collections problem

A rising accounts receivable balance needs to be read alongside revenue. If revenue grew and receivables grew proportionally, the pattern is normal. If receivables are growing faster than revenue, or if the aging report shows an increasing proportion of older balances, the business is collecting more slowly. That can happen because payment terms have lengthened, because specific customers are becoming slow payers, or because invoicing is happening later than it should. The aging report distinguishes between these causes; the total balance alone does not.

It is a direct lever on the cash flow gap

The cash flow gap, the period between when cash goes out and when it comes in, is determined partly by how quickly receivables convert to cash. A business that moves from 45-day average collection to 30-day collection closes the gap by two weeks on every invoice cycle. That improvement does not require any change to pricing, costs, or revenue volume. The cash was always coming; it just arrives sooner. For businesses where the gap regularly creates cash pressure, tightening collections is usually the fastest available response.

Receivables are sales made but not yet paid for, cash sitting in customers' accounts. How fast they pay sets the inflow timing.

That timing is the entire issue. Revenue recognised in October on 60-day terms arrives in December. The staff who did the work were paid in October. The gap between those two months is funded by the cash balance, a credit line, or both. If the receivables balance grows because the business is scaling, that gap widens in absolute terms even if the collection cycle stays the same. A business doubling its revenue on the same payment terms needs to fund twice the receivables balance before the cash starts flowing at the higher level. That working capital requirement is real, and it is proportional to how large the receivables balance is relative to the monthly revenue.

The cash flow forecast reflects receivables timing whether or not the business tracks DSO explicitly. A forecast built from actual outstanding invoices, with expected payment dates based on terms and customer payment history, will show when each receivable is expected to convert to cash, and therefore when the bank balance is likely to rise. When that timing shifts, a customer that usually pays in 30 days takes 50, the forecast catches it as a projected shortfall before the bank statement does. That lead time is what makes the forecast useful rather than just descriptive.

Cash Flow Frog connects to QuickBooks Online, QuickBooks Desktop, Xero, and Sage Intacct and builds a rolling cash flow forecast automatically from your accounting data. QuickBooks records what happened. Cash Flow Frog projects what is coming.

Because the forecast pulls from live accounting data, the outstanding invoices in the accounts receivable ledger feed directly into the projected cash inflows, not as a smoothed monthly estimate, but as actual invoices with expected collection dates. When a customer pays or an invoice goes overdue, the accounting system updates and the forecast reflects the change. If you want to trace which specific invoices are affecting the projected balance in a particular week, the tool drills down to the transaction level. For businesses with customers across multiple currencies or entities, the receivables picture consolidates natively. You can explore the forecasting features at cashflowfrog.com/features/forecast/.

Frequently Asked Questions

Is accounts receivable an asset or income?

It is an asset, specifically, a current asset on the balance sheet. The corresponding income was recognised on the income statement when the invoice was raised. Accounts receivable represents the uncollected portion of that recognised income: the business has already recorded the revenue, but the cash has not yet arrived. Once the customer pays, the receivables balance falls and the cash balance rises by the same amount.

Revenue is recorded on the income statement when goods are delivered or services are performed, regardless of when payment is received. Accounts receivable is the balance sheet account that holds the uncollected portion of that revenue. When an invoice is issued, revenue goes up on the income statement and accounts receivable goes up on the balance sheet by the same amount. When the invoice is paid, accounts receivable goes down and cash goes up, but revenue does not change, because it was already recorded at the point of invoicing.

What happens to accounts receivable that is never collected?

It becomes a bad debt. The business writes off the uncollectable amount by removing it from accounts receivable and recording a bad debt expense on the income statement, which reduces profit. Some businesses maintain a bad debt provision, an estimate of the receivables balance that is unlikely to be collected, which allows the income statement to absorb expected losses before specific invoices are formally written off. Either way, uncollected receivables that are written off reduce both profit and the balance sheet asset, but they do not directly affect cash, because the cash was never received in the first place.

A receivables aging report groups outstanding invoices by how long they have been unpaid: typically current (0–30 days), 31–60 days, 61–90 days, and over 90 days. It shows, at a glance, how much of the total receivables balance is recent and how much is overdue. Businesses use it to prioritise collections activity, focusing follow-up on the oldest and largest balances first, and to assess the overall credit quality of the receivables book. An aging report with a growing proportion of older balances is an early warning that collection performance is deteriorating.

Can a business sell its receivables?

Yes. Invoice factoring and invoice discounting are two mechanisms that allow a business to receive cash against outstanding receivables before the customer pays. In factoring, the factoring company buys the invoices and takes on the collections process; in discounting, the business retains control of collections and repays the advance when the customer pays. Both involve a fee or interest charge. These tools are most commonly used by businesses with long payment cycles and a need for faster cash, they do not eliminate the receivables gap, but they shift who funds it.

How does offering early payment discounts affect accounts receivable?

It reduces the collection period at the cost of a small reduction in the amount received. A business offering 2% off for payment within 10 days instead of the standard 30 will collect faster from customers who take the discount, which lowers the average DSO and reduces the receivables balance. Whether that trade-off is worth making depends on the business's current cash position, the cost of alternative funding, and how many customers actually take the discount. For a business paying interest on a credit line to fund its receivables gap, a 2% discount that eliminates the need to draw on that line may cost less than the interest it replaces.
