Summary:
Accounts receivable (AR) is money owed to a business by its customers for goods or services already delivered but not yet paid for — recorded as a current asset on the balance sheet because the company expects to collect it within a short period, typically 30 to 90 days.
- Current asset: AR appears on the balance sheet as an asset because it represents a legal claim to future cash — but it’s only as valuable as the company’s ability to collect it.
- Distinct from revenue: Under accrual accounting, revenue is recorded when earned (when the sale occurs), not when cash arrives — creating AR in the gap between the two.
- Days Sales Outstanding (DSO): The key metric for AR efficiency — how many days on average it takes to collect payment after a sale.
- Financing option: Businesses can convert unpaid AR into immediate cash through AR financing or factoring, using outstanding invoices as collateral.
Accounts receivable sits at the intersection of sales and cash flow — a business can be profitable on paper and cash-strapped in practice if customers are slow to pay. Managing AR well is less about accounting and more about keeping money moving through the business.
What is accounts receivable?
Accounts receivable is the total amount customers owe a business for credit sales — transactions where goods or services were delivered but payment hasn’t been collected yet. It’s the natural result of selling on credit terms, which most businesses do to remain competitive and accommodate customers who prefer to pay on net-30, net-60, or net-90 terms.
AR is classified as a current asset because it’s expected to convert to cash within 12 months. It sits alongside cash, inventory, and short-term investments in the current assets section of the balance sheet. The higher the AR balance relative to revenue, the longer customers are taking to pay — which can signal collection problems or overly lenient credit terms.
How accounts receivable works
The AR cycle follows a predictable sequence. A business delivers a product or service and issues an invoice specifying the amount owed and the payment due date. The receivable is recorded immediately in the accounting system under accrual accounting — revenue is recognized at the point of sale, not when cash arrives. When the customer pays, the AR balance decreases and cash increases by the same amount.
The detailed record of what each individual customer owes — broken out by invoice — is tracked in an accounts receivable subsidiary ledger. The subsidiary ledger rolls up to the AR total on the balance sheet, allowing businesses to monitor the payment status of each customer account separately.
Some businesses accept paper checks as payment, which may be converted to electronic ACH debits through an accounts receivable conversion (ARC) check — speeding up processing and reducing handling costs.
Accounts receivable on the balance sheet
AR is recorded at its expected collectible value — not the full invoice amount if some portion is unlikely to be paid. Companies that sell on credit maintain an allowance for doubtful accounts, a contra-asset that reduces AR to its net realizable value. The allowance is estimated based on historical collection rates, the age of outstanding invoices, and the creditworthiness of customers.
For example, if a business has $500,000 in AR but estimates that $25,000 is unlikely to be collected, the balance sheet reports net AR of $475,000. When a specific account is confirmed uncollectible, it’s written off against the allowance — reducing both AR and the allowance without affecting the income statement at that point.
Key accounts receivable metrics
Days Sales Outstanding (DSO)
DSO measures how long it takes on average to collect payment after a sale. It’s calculated as:
DSO = (Accounts Receivable ÷ Total Credit Sales) × Number of Days
A DSO of 45 means customers take an average of 45 days to pay. Lower is generally better — it means cash is cycling through the business faster. DSO above the stated payment terms (e.g., DSO of 60 on net-30 invoices) signals collection inefficiency or customer payment problems.
AR turnover ratio
AR turnover measures how many times per period a business collects its average AR balance. Higher turnover indicates more efficient collection. It’s calculated as net credit sales divided by average AR for the period. A low turnover ratio — relative to industry benchmarks — suggests customers are taking too long to pay or that credit is being extended too loosely.
| Metric | Formula | What It Signals |
|---|---|---|
| Days Sales Outstanding (DSO) | (AR ÷ Credit Sales) × Days | Average collection time; lower = faster cash conversion |
| AR Turnover Ratio | Net Credit Sales ÷ Average AR | Collection efficiency; higher = more efficient |
| Bad Debt Ratio | Bad Debt Expense ÷ Net Credit Sales | Share of sales never collected; tracks credit risk |
Accounts receivable financing
Businesses that need immediate cash but have capital tied up in unpaid invoices can use AR as collateral through several financing structures.
Accounts receivable financing allows a business to borrow against outstanding invoices — the lender advances a percentage of the AR balance (typically 70–90%) and holds the invoices as collateral. The business retains the customer relationship and collects payment directly, then repays the advance plus fees. To compare lenders, see accounts receivable financing providers on SuperMoney.
Factoring goes further — the business sells its invoices outright to a factoring company at a discount. The factor takes ownership of the receivables, assumes collection responsibility, and advances most of the invoice value immediately. It’s faster than a loan but more expensive and involves the factor contacting your customers directly.
A third option is assignment of receivables — pledging specific invoices as collateral for a loan without selling them, retaining more control over the customer relationship while still accessing liquidity.
Pro Tip
Aging your AR weekly — categorizing outstanding invoices by how long they’ve been unpaid (0–30 days, 31–60, 61–90, 90+) — is the simplest way to catch collection problems before they become write-offs. Invoices past 90 days have significantly lower collection rates; the sooner follow-up begins, the higher the recovery.
Key takeaways
- Accounts receivable is money owed to a business for goods or services already delivered — recorded as a current asset because it represents expected future cash.
- AR is created under accrual accounting when revenue is recognized at the point of sale, before cash is collected.
- Net AR on the balance sheet reflects the expected collectible amount after subtracting an allowance for doubtful accounts.
- Days Sales Outstanding (DSO) is the primary metric for measuring collection efficiency — DSO above your stated payment terms signals a problem.
- AR financing and factoring allow businesses to convert outstanding invoices into immediate cash, using receivables as collateral or selling them outright.
- An AR subsidiary ledger tracks each customer’s balance individually, enabling businesses to monitor and follow up on specific accounts.
Frequently asked questions
What is the difference between accounts receivable and accounts payable?
Accounts receivable is money others owe your business — a current asset. Accounts payable is money your business owes to suppliers and vendors — a current liability. They’re mirror images: your AR is your supplier’s AP. Managing both well is essential to maintaining healthy working capital.
Is accounts receivable the same as revenue?
No. Revenue is earned when a sale occurs; AR is what remains uncollected from that sale. Under accrual accounting, a $10,000 sale on net-30 terms immediately adds $10,000 to revenue and $10,000 to AR. When the customer pays, AR decreases by $10,000 and cash increases — revenue is unaffected because it was already recorded.
What happens when accounts receivable is not collected?
If a specific invoice becomes uncollectible, the business writes it off — removing it from AR and reducing the allowance for doubtful accounts. If the allowance is insufficient to cover the write-off, the excess hits bad debt expense on the income statement. Repeated write-offs signal overly loose credit terms or inadequate collection processes.
How does accounts receivable affect cash flow?
An increase in AR is a use of cash on the cash flow statement — the business earned revenue but hasn’t collected it yet. A decrease in AR is a source of cash — old receivables were collected. Companies with rapid AR growth relative to revenue may look profitable on the income statement while struggling with actual cash availability, a common issue for fast-growing businesses.
What is a normal DSO?
DSO benchmarks vary significantly by industry. Professional services firms often run 45–60 days; manufacturers may target 30–45 days; retailers with mostly cash sales have near-zero DSO. The most meaningful comparison is your DSO against your own stated payment terms — if you offer net-30 and your DSO is 55, you have a collection gap worth addressing.
