Quick Summary

• Accounts receivable is money customers owe you for goods or services already delivered on credit. It's a current asset, and until the cash lands it's a promise rather than money
• Revenue is recognized at the invoice, not at the payment. That single accrual rule is why collections and DSO exist as disciplines
• Gross AR is optimistic. Net AR, after the allowance for doubtful accounts, is the number you can count on
• CECL replaced the old incurred-loss model. Allowances now reflect lifetime expected credit losses, estimated forward-looking rather than only from history
• US GAAP requires the allowance method. Direct write-off is generally acceptable only for immaterial amounts
• AR can be turned into cash early or de-risked through factoring, invoice discounting, asset-based lending, or trade credit insurance, each at a cost
• AR is the back half of order-to-cash, which is why a problem that surfaces as slow collections usually started upstream

Nobody argues about what good AR looks like. Finding the hours to actually do it is another story.

What is accounts receivable?

Accounts receivable is money your customers owe you for goods or services you have already delivered. You did the work. They haven't paid for it yet. Payment is due inside an agreed window, usually 30 to 90 days, and on the balance sheet AR sits as a current asset, because you expect to convert it to cash within a year.

Until the money lands, it's a promise.

Finance teams live in the stretch between the sale and the payment. Managed well, it's quiet country, and cash arrives on schedule. Managed badly, it turns into the Wild West, with invoices wandering wherever they please and growth stalling while you refresh the bank feed.

Accounts receivable vs accounts payable

The two get mixed up constantly, so here is the clean version:

• Accounts receivable is money owed to you by customers
• Accounts payable is money you owe to suppliers and vendors

One is cash coming in and the other is cash going out. They're mirror images across a single transaction, since your receivable is somebody else's payable.

Both run on credit terms, and the timing between them decides how much working capital you tie up. If your customers pay you in 60 days while you pay suppliers in 30, you're the bank now. Pulling those timings closer together is one of the quiet wins of good finance work.

Types of receivables

Trade receivables are the default. They cover money owed for your normal goods or services, and they're what almost everyone means by accounts receivable.

Other categories exist and occasionally matter:

• Notes receivable are backed by a formal written promissory note, often carrying interest and a longer term
• Interest receivable is interest earned but not yet collected
• Rent receivable is rent owed to you but not yet paid
• Loan and other receivables cover money owed outside the normal sale of goods or services

For most B2B finance teams, trade receivables are the whole game.

How accounts receivable works on the balance sheet

AR sits among current assets, usually near the top, just after cash itself. The ordering reflects liquidity, and receivables are among the fastest assets to convert. In theory, anyway.

The logic is simple. You earned the revenue when you delivered the work. The customer hasn't paid yet, so you record what they owe as an asset and wait for the money to catch up.

The journal entries behind AR

Two entries do most of the work. Say you invoice a customer $10,000:

• At invoice: debit Accounts Receivable $10,000, credit Revenue $10,000
• At payment: debit Cash $10,000, credit Accounts Receivable $10,000

The first records the sale. The second clears the receivable once cash arrives.

Between those two moments, the $10,000 is yours on paper and nowhere else.

Why AR is recognized at invoice, not at cash

This is the detail that makes everything else matter. Under accrual accounting you book revenue when it's earned, at the invoice, rather than when cash shows up. The receivable bridges the two events.

That single rule is the reason collections and DSO exist as disciplines. If revenue only counted when cash arrived, nobody would ever need to chase anything. It does not, so here we are.

Because you recognize revenue early, the job becomes turning it into real money before it goes stale.

Gross AR vs net AR

Two figures, and they answer different questions:

• Gross AR is the total your customers owe
• Net AR is that figure minus the allowance for doubtful accounts

When someone asks how much you're owed, net AR is the honest answer.

Unbilled AR and accrued revenue

Unbilled AR, also called accrued revenue, is a close cousin and a distinct one. It's revenue you have earned but not yet invoiced, common in usage-based and milestone billing.

It only becomes accounts receivable the moment you bill it, because until then no invoice exists.

Keep the two separate. Your reporting stays clean, and your auditors will ask anyway.

The allowance for doubtful accounts

Not every invoice gets paid. Some customers dispute, and a few simply go quiet.

Accounting handles this with an allowance for doubtful accounts, also called an allowance for credit losses or a bad debt reserve. You estimate how much of your AR is unlikely to be collected and record it as a contra-asset, which offsets the value of the related asset and pulls gross AR down to a realistic net figure.

How to estimate the allowance

The framework changed. ASC 326, known as CECL, replaced the old incurred-loss model and applies to trade receivables. It took effect for most SEC filers in 2020 and for all other entities in fiscal years beginning after December 15, 2022, so by now it applies broadly.

The practical difference is the direction you look. The old model recorded losses once they were probable. CECL requires an estimate of lifetime expected credit losses built from three inputs:

• Historical loss experience on comparable receivables
• Current conditions affecting your customer base
• Reasonable and supportable forecasts of what is coming

Two estimation methods are in common use, and they're no longer equal:

• The aging method, sometimes called percentage-of-receivables, groups open balances by how far past due they're and applies escalating loss rates to older buckets. It's balance-sheet focused, and it's the approach FASB itself illustrates for trade receivables under CECL, which makes it the most common choice
• The percentage-of-sales method applies a historical bad debt rate to credit sales for the period. It's income-statement focused, and used alone it doesn't tie the estimate to how overdue the book currently is, which is why most companies pair it with an aging overlay rather than relying on it by itself

ASC 326 doesn't mandate a specific methodology, so judgment and documentation both matter. One quirk worth knowing is that the allowance includes expected recoveries of amounts previously written off, which can produce a negative allowance on a given pool.

Readers outside the US should note that IFRS 9 runs its own expected credit loss model. The direction of travel is the same, and the mechanics differ.

Note: In July 2025, FASB issued ASU 2025-05, giving private companies and certain not-for-profits a practical expedient for AR and contract assets. Instead of forecasting future economic conditions, you can simply assume conditions at the balance sheet date persist for the life of the asset. It also lets private companies factor in collections received after the balance sheet date but before the financials are issued. The effective date is fiscal years beginning after December 15, 2025, so it's now current for most calendar-year private companies.

Writing off bad debt

Two methods exist and only one is generally acceptable:

• The allowance method records the estimated loss up front, then writes the bad invoice off against the allowance when it goes bad. This is what US GAAP requires
• The direct write-off method records nothing until an invoice is confirmed uncollectible, then expenses it. It violates the matching principle, so it's generally acceptable only for immaterial amounts or for tax purposes

The timing rule is worth stating plainly. You write off a receivable in the period you determine it's uncollectible, which generally means once all reasonable means of recovering it have been exhausted.

A worked example, start to finish

A realistic sequence makes the mechanics concrete.

On March 1 you deliver a $10,000 project and invoice on net 30 terms. You debit Accounts Receivable $10,000 and credit Revenue $10,000. Your AR balance rises, and revenue hits the income statement even though no cash has moved.

For the next 30 days that $10,000 sits in current AR. It's inside terms, so no chasing is needed, only a pre-due confirmation that the invoice arrived and looks right.

On April 2 the customer pays by ACH. You debit Cash $10,000 and credit Accounts Receivable $10,000. The receivable clears, cash rises, and the account returns to zero.

That's the clean path. Most of AR is the work of keeping every invoice on it, and rounding up the ones that stray before they age into a problem.

Why accounts receivable matters

AR is often one of the largest current assets on a company's books, and a surprising share of it is late. In its 2025 US Payment Practices Barometer, Atradius found that 43% of the value of B2B invoices in the US was overdue, with a further 5% written off as bad debt.

That's your money, doing nothing, in someone else's account. It can't pay salaries or fund the next hire from there.

Three reasons it deserves real attention:

• Working capital. Cash stuck in receivables is cash you can't put to work, and it scales with revenue rather than shrinking as you grow
• Cash flow. Late payments undermine your ability to forecast and commit with any confidence
• Liquidity. Healthy AR keeps the gap between paying suppliers and collecting from customers manageable without external funding

A company that collects quickly reinvests that cash sooner. A company that collects slowly borrows or raises to cover the same gap, which costs real money and slows everything down.

Treat AR as a lever on how fast you can grow. The accounting is just how you keep score.

Where AR sits in the order-to-cash cycle

AR doesn't stand alone. It lives inside the wider order-to-cash cycle, sometimes called invoice-to-cash, which runs from a customer placing an order to the payment being fully reconciled.

The cycle covers the order and credit decision, fulfillment, invoicing, collections, payment, cash application, and reporting.

AR is the back half of that flow, everything from the invoice onward. When people say their order-to-cash process is slow, the delay almost always lives in AR, because that's where the money has to come back.

Seeing AR as part of the wider cycle matters for one practical reason. A problem that surfaces as slow collections usually started earlier, in a bad credit decision or a broken invoice.

Chasing harder doesn't fix a problem created upstream.

Who owns accounts receivable

On a small team, one person holds the whole thing. As you scale, the work splits across roles:

• AR analyst or specialist owns the day-to-day of invoicing, tracking, and applying cash
• Collections specialist owns the follow-up, including reminders, calls, and past-due accounts
• Credit manager owns the front end, setting credit checks, limits, and terms
• Controller owns the accounting, covering the ledger, the allowance, and the close
• CFO owns the outcome, meaning DSO, cash forecasting, and the board conversation

These roles all make sense on paper. The trouble at scale is that the full picture of any single account gets scattered across all of them, plus the ERP, the CRM, and somebody's memory.

Once nobody holds the whole account, the downstream work goes sideways. You chase the wrong contact, chase a disputed invoice, or chase someone who already paid. Ask any collector which of the three stings most.

Accounts receivable financing

Receivables are an asset, which means they can be converted to cash early or insured against loss. Four options come up regularly.

Factoring

You sell an invoice, or a book of invoices, to a factor at a discount. They advance most of the value immediately and collect from your customer directly.

The distinction that matters is who carries the risk:

• Recourse factoring leaves the credit risk with you. If the customer never pays, you buy the receivable back
• Non-recourse factoring transfers the credit risk to the factor, usually for a higher fee and against approved customers only

Factoring is visible to your customer, since they pay the factor rather than you. Some businesses accept that and some will not.

Invoice discounting

You borrow against the value of your receivables book while continuing to collect yourself. The facility usually revolves as invoices are raised and settled.

It's often confidential, meaning the customer never knows the facility exists. That makes it a common choice for businesses that want the cash flow benefit without changing the customer relationship.

Asset-based lending

A broader revolving facility secured against your assets, typically receivables and often inventory as well. Availability moves with the value of the collateral.

It suits larger businesses with a substantial and reasonably predictable AR book.

Trade credit insurance

Rather than accelerating cash, this protects against not receiving it. You insure your receivables against customer insolvency or protracted default, and the insurer pays out a percentage of the loss.

Beyond the payout, insurers underwrite your customers, which gives you a second opinion on credit risk.

The trade-off is consistent across all four. You're paying a spread for speed or for protection. Whether that's worth it depends on what the same cash would earn deployed in the business, and on how reliable your book actually is.

What great accounts receivable looks like

Before the mechanics of the process, it helps to name the standard, because almost nobody argues about what good looks like.

Done brilliantly, AR treats every account as an individual across the whole lifecycle:

• The credit decision is right at the start, with terms matched to the risk and the customer's real AP process captured before the first invoice
• The invoice is clean and arrives payable, landing with the right contact, in the right portal, with a valid PO attached
• Receipt is confirmed before the due date, so a missing PO surfaces while the invoice is still current
• Outreach is individual, matched to the customer, their payment history, and the state of the relationship
• Cash is applied quickly and accurately, so credit frees up and the aging report tells the truth
• Disputes come out of the chase immediately and get resolved before they damage anything

That's the bar. Every section that follows is measured against it.

Most teams could describe that standard without prompting. What stops them is capacity. Too much territory, not enough riders. So they pick two or three key segments, standardize everything else, and watch the long tail age in the report.

Teams run out of hours long before they run out of knowledge. That distinction runs through the rest of this guide.

FAQs

Is accounts receivable an asset or a liability?

An asset. AR is a current asset, since you expect to collect it within a year. It's what customers owe you.

What is the difference between accounts receivable and accounts payable?

Accounts receivable is money customers owe you. Accounts payable is money you owe suppliers. AR brings cash in and AP sends cash out. They're mirror images across a transaction.

Is accounts receivable a debit or a credit?

A debit. As an asset, AR rises with a debit and falls with a credit. You debit AR when you raise an invoice, and credit it when the customer pays.

What is the allowance for doubtful accounts?

A contra-asset that reduces gross AR to the amount you realistically expect to collect. Under CECL, it reflects lifetime expected credit losses estimated from historical experience, current conditions, and forward-looking forecasts.
