Accounts receivable is the money customers owe a business for goods or services that have already been delivered but not yet paid for. It sits on the balance sheet as a current asset and functions as a short-term, interest-free loan the seller has extended to the buyer. For any company that invoices customers instead of collecting at the point of sale, accounts receivable is often one of the largest assets on the books and a direct driver of cash flow.
How a Receivable Is Created
A receivable comes into existence the moment a business delivers a product or completes a service and issues an invoice instead of taking payment on the spot. This arrangement is called trade credit. It is standard in business-to-business transactions and appears in some consumer-facing industries as well. The invoice states what was sold, the total amount due, and the deadline for payment.
Payment deadlines are written as “net” terms. Net 30 gives the customer 30 calendar days from the invoice date to pay in full. Net 60 and Net 90 push the window further out. Some sellers offer an early-payment discount to speed collection. Terms of “2/10 Net 30” mean the buyer takes a 2 percent discount by paying within 10 days; otherwise the full balance is due at 30.
Until the customer pays, the outstanding balance sits in accounts receivable. It is an unsecured claim, meaning no collateral backs it. If the customer refuses to pay or files for bankruptcy, the seller has no property to seize. That risk is why the way a business manages its receivables matters as much as the sales that generate them.
How Accounts Receivable Is Recorded
Under accrual accounting, revenue is recognized when the business satisfies its performance obligation, not when cash arrives. The IRS applies the same logic for accrual-method taxpayers: income accrues when the right to receive it is fixed and the amount can be determined with reasonable accuracy.1Internal Revenue Service. IRS Notice 15-40 Under ASC 606, a receivable exists when a company’s right to consideration is unconditional, meaning only the passage of time stands between the invoice and payment.2Financial Accounting Standards Board. Revenue from Contracts with Customers Topic 606
Because businesses expect to collect these balances within a year, accounts receivable is classified as a current asset.3Legal Information Institute. Current Asset But the raw total of outstanding invoices overstates what the company will actually collect. Some customers default. That is why the balance sheet reports accounts receivable at its net realizable value: the gross balance minus an estimated allowance for accounts that will never be paid.
Estimating Uncollectible Accounts
No business collects every dollar it invoices. The allowance for doubtful accounts is a contra-asset that reduces gross receivables to a realistic estimate of what will actually come in. Building the allowance requires recording a bad debt expense in the same period the related revenue was recognized, so losses match the sales that produced them.4Securities and Exchange Commission. Significant Accounting Policies – Section: Accounts Receivable and Allowance for Doubtful Accounts
Two traditional approaches have long been standard. The percentage-of-sales method applies a historical loss rate to the period’s total credit sales, producing a single expense figure. The aging-of-receivables method sorts every outstanding invoice into buckets by how long it has been overdue and applies progressively higher loss percentages to older buckets. Because it looks at the actual condition of the portfolio, aging tends to produce a more precise estimate.
The Shift to Expected Credit Losses
In 2016, the Financial Accounting Standards Board introduced ASC 326, which changed how companies estimate credit losses. Known as the Current Expected Credit Losses methodology, it requires businesses to estimate the total lifetime losses they expect on receivables at the time those receivables are recorded, rather than waiting until a loss is “probable” under the old incurred-loss model.5National Credit Union Administration. CECL Accounting Standards The standard applies to all financial instruments carried at amortized cost, including trade receivables.6Federal Reserve Board. Frequently Asked Questions on the New Accounting Standard on Financial Instruments – Credit Losses
For larger public companies the standard took effect in 2020. For smaller reporting companies, private companies, and most not-for-profits, it became effective for fiscal years beginning after December 15, 2022.5National Credit Union Administration. CECL Accounting Standards In practice, using the old percentage-of-sales method alone no longer satisfies the standard for most entities. Companies now have to incorporate forward-looking information, including economic forecasts, when setting the allowance.
Writing Off a Specific Account
When a company determines that a particular customer will never pay, it writes off the balance by reducing the allowance for doubtful accounts and gross accounts receivable by the same amount. The write-off does not create a new expense, because the estimated loss was already recognized when the allowance was built.7Cornell University Division of Financial Services. Allowance for Doubtful Accounts and Bad Debt Expenses
Tax Treatment of Bad Debts
Not every uncollectible receivable qualifies for a tax deduction. The IRS allows businesses to deduct a bad debt only if the amount owed was previously included in gross income for the current or a prior tax year.8Internal Revenue Service. Topic No. 453, Bad Debt Deduction That effectively limits the deduction to accrual-method businesses. Cash-basis taxpayers never reported the income in the first place, so there is nothing to deduct when a customer fails to pay.
To claim the deduction, the debt must be genuinely worthless. You have to show that you took reasonable steps to collect and that there is no realistic expectation of payment. Filing a lawsuit is not required if you can demonstrate that a court judgment would be uncollectible anyway. The deduction is taken in the year the debt becomes worthless, and partial write-offs are allowed for business bad debts.8Internal Revenue Service. Topic No. 453, Bad Debt Deduction
Managing Receivables Day to Day
The accounting matters, but the real work happens between the moment an invoice goes out and the moment cash lands in the bank.
Credit Policy
Every AR operation starts with a credit policy set before the first sale. The policy establishes who qualifies for credit, how much credit each customer can carry, and what payment terms apply. Setting terms too loosely invites slow payers. Setting them too tightly drives customers to competitors. Most businesses review customer creditworthiness at onboarding and periodically after, adjusting limits based on payment history and financial condition.
Invoicing
Slow or sloppy invoicing is one of the most common reasons receivables age unnecessarily. An invoice should go out immediately after delivery, and it should state the amount due, the payment terms, and the exact due date without ambiguity. Any confusion on those points gives a customer a reason to delay.
Collections
Collection activity starts before an invoice is overdue. Automated reminders a few days ahead of the due date prompt customers who simply forgot. Once an invoice goes past due, the cadence tightens through personalized emails, phone calls, and eventually formal demand letters. If internal efforts fail, the final escalation is typically a referral to a third-party collection agency or legal action. Each step costs time and money, which is why early, consistent follow-up prevents most accounts from ever reaching that stage.
Measuring How Well It’s Working
Two ratios show how efficiently a company turns invoices into cash. Tracked over time, they reveal whether receivables management is improving or drifting.
Days Sales Outstanding
Days sales outstanding measures the average number of days it takes to collect payment after a sale:
DSO = (Accounts Receivable ÷ Total Credit Sales) × Number of Days in the Period
A company with $500,000 in receivables and $3,000,000 in credit sales over a 90-day quarter has a DSO of 15 days. That would be excellent. A DSO of 60 in an industry where standard terms are Net 30 signals that customers are paying late, the credit policy is too generous, or collections need work. The number is most useful compared against the company’s own payment terms and against direct competitors.
Accounts Receivable Turnover Ratio
The turnover ratio measures how many times a company collects its average receivable balance during a period:
AR Turnover Ratio = Net Credit Sales ÷ Average Accounts Receivable
Average accounts receivable is the sum of the beginning and ending balances, divided by two. A higher ratio means faster collection. A ratio of 10 means the company collected its average receivable balance 10 times during the year, roughly every 36 days. A low ratio suggests too much credit extended, too slow to collect, or both.
Turning Receivables Into Cash Early
Receivables do not have to sit on the balance sheet until customers pay. Two common options let a business unlock cash tied up in outstanding invoices.
Invoice Factoring
In factoring, a business sells its outstanding invoices to a factoring company at a discount. The factor advances a percentage of the invoice value upfront, typically 70 to 90 percent, and then collects directly from the customer. Once the customer pays, the factor remits the remaining balance minus its fee, which generally runs between 1 and 5 percent of the invoice value per 30 days. The factor takes over collection and communicates with the customer directly.
That loss of control is the trade-off. Some customers view contact from a factoring company negatively, and the business gives up its direct relationship on those invoices. Fees also add up quickly on invoices with longer payment cycles.
Accounts Receivable Financing
AR financing, sometimes called invoice financing, uses outstanding receivables as collateral for a loan or line of credit instead of selling them outright. The business keeps ownership of the invoices and stays responsible for collection. The lender advances a portion of the receivable value and charges interest or fees on the borrowed amount. Because the customer relationship stays in-house, this option is usually less disruptive than factoring, though it adds a borrowing cost on top of the existing receivable.
Either approach makes sense when a business has strong receivables but needs cash faster than its customers pay. The choice usually comes down to whether the business wants to hand off collections or keep them, and how sensitive its customer relationships are to third-party involvement.
