What Is Accounts Receivable and How Does the AR Process Work

Imagine you close a strong month on paper, then check the bank balance and wonder where the money is. That gap between booking revenue and collecting it is accounts receivable, and for a growing company it often decides whether you can confidently make payroll, hire, or restock. The sooner you get a handle on it, the less your cash flow runs on guesswork.

In this guide, we explore what accounts receivable is, how the AR process works step by step, and how to record it, with worked examples along the way.

In brief:

• Accounts receivable is money customers owe you for goods or services delivered on credit but not yet paid.
• AR is a current asset with a normal debit balance, shown net of the allowance for doubtful accounts.
• The AR cycle runs from setting credit terms through invoicing, recording the sale, collections, and cash application.
• Track days sales outstanding (DSO): accounts receivable divided by total credit sales, times the days in the period.
• Under GAAP, uncollectible invoices are written off through the allowance for doubtful accounts, not booked as a direct expense.

What is accounts receivable?

Accounts receivable is money customers owe your business for goods or services you've delivered but haven't collected payment for yet. When a company finishes a project or ships an order and sends an invoice, that unpaid amount becomes accounts receivable, and it exists whenever a business sells on credit rather than collecting cash up front.

What is the difference between accounts receivable and accounts payable?

Accounts payable is the mirror image of accounts receivable, since the same invoice that sits in the seller's AR sits in the customer's accounts payable. If Company A cleans Company B's carpets and sends a bill, Company A records accounts receivable while Company B records accounts payable.

Accounts receivable is an asset, and it sits in current assets on the balance sheet because a business expects to convert it to cash within one year, or within one operating cycle if that cycle runs longer.

When a customer's payment terms stretch beyond a year, the business classifies that portion outside current assets. Because it's an asset, AR carries a normal debit balance, so a debit increases the account and a credit decreases it.

The balance sheet usually shows AR after subtracting the allowance for doubtful accounts, the estimate of receivables the business doesn't expect to collect. That net figure is what lenders, boards, and liquidity measures like the quick ratio actually rely on, since it reflects what the company realistically expects to receive.

Examples of accounts receivable

Two short examples show how AR moves, first for a single invoice and then across a full month on the balance sheet.

Single-invoice example

Say a consulting firm issues a $10,000 invoice dated June 1 with Net 30 terms, so the client has until June 30 to pay. On June 1, the firm debits accounts receivable $10,000 and credits service revenue $10,000, and when the client pays, it debits cash $10,000 and credits accounts receivable $10,000 to close the invoice.

A common variant adds an early payment discount written as 2/10 Net 30, where the client gets a 2% discount, or $200 here, for paying within 10 days and otherwise owes the full amount at 30 days. For the seller, that discount can be a cheap way to pull cash forward when cash is tight.

Accounts receivable on the balance sheet

The AR balance moves with a simple formula, where ending AR equals beginning AR plus new credit sales, minus collections, minus write-offs. Start the month with $5,000 in receivables, invoice $10,000 in new credit sales, and collect $4,000 with no write-offs, and you end with $11,000.

That $11,000 sits under current assets, net of the allowance for doubtful accounts. If a business estimates $500 won't be collected, the balance sheet shows net receivables of $10,500, and that net number is what lenders and board members should be looking at.

Some invoices never get paid. In the US, the credit insurer Atradius found that 43% of B2B invoices are overdue and that bad debts run at about 5% of total B2B invoice value.

GAAP handles the shortfall through the allowance method, where at each period end a business estimates the uncollectible portion of AR, debits bad debt expense, and credits the allowance for doubtful accounts.

When a specific invoice proves uncollectible, the business debits the allowance and credits AR to remove it, with no fresh hit to the income statement. The tax treatment depends on the accounting method, since accrual-basis businesses can deduct uncollectible receivables because they already reported the income.

For invoices 90 or more days past due, a collections agency is an option, though agencies keep a share of what they recover and collectability drops as debt ages.

6 steps in the accounts receivable (AR) process

The full accounts receivable cycle covers everything from the first credit decision through final payment reconciliation. At a smaller company, one person often owns most of these steps, and as your team grows, clean handoffs between sales and finance start to matter more.

1. Agree terms and extend credit

Before a customer can pay later, you decide whether they've earned the privilege. The 5 Cs framework looks at character, capacity, capital, collateral, and conditions, and a company can apply the idea without a formal credit department, since even a quick check of payment history and references beats extending Net 30 on instinct.

A credit policy should also spell out who can release orders when a customer is past due, and whether marginal accounts need a deposit or a personal guarantee. At a 50-person company, that owner is usually the finance lead or the founder.

So, if there's no policy yet, start with approval authority for terms and overrides plus a clear response for when a customer pays late twice.

2. Deliver the goods or service and issue the invoice

Send the invoice the day the work is delivered so the payment period starts right away. The cycle often begins with a customer purchase order. Once the order is approved, accounting creates an invoice covering the products or services provided, the payment terms, the due date, and any applicable taxes.

Errors in invoice details or PO numbers cause disputes, and disputes cause delays, so every invoice should carry the details a customer needs to approve and pay it without another email thread:

• Amount due: Show the total clearly, including taxes, discounts, retainers, or credits. A customer who has to do the math is a customer who pays late.
• Due date: State the exact payment due date alongside the terms, such as Net 30, so there's no ambiguity about when the clock runs out.
• Payment methods: List the payment options you accept so the customer doesn't have to email and ask, which only adds days.
• Invoice number: Use a unique invoice number the team can match later during cash application, which keeps reconciliation clean.

With a clean invoice out the door, the next step is recording what the customer now owes.

3. Record the receivable

Under accrual accounting, a business records the sale when it earns the revenue rather than when the cash lands. Issuing the invoice creates two entries at once: a debit to accounts receivable on the balance sheet and a credit to revenue on the income statement.

Cash-basis businesses skip this step because they don't track AR between invoicing and payment. That's one reason accrual accounting gives a clearer picture of company health for any team that sells on credit.

4. Track, follow up, and collect payment

Once the invoice goes out, someone has to watch it. If a customer misses the due date, the collections process, often called dunning, begins with scheduled follow-ups that escalate as the invoice ages, moving from a reminder before the due date, to a phone call around day 7 past due, to a formal notice at day 30, and a written promise to pay or demand by day 60.

Collections work best when you set expectations early and treat the first missed date as a warning signal. We'd contact the client on the first day a payment is late, before the account is a month behind, rather than assume they'll sort it out without a nudge.

5. Reconcile the payment and close the invoice

When the money arrives, the finance team matches it to the right open invoices, a step called cash application. A single payment might cover dozens of invoices, or it may not match any invoice exactly and force some investigation; remittance advice from the customer can speed up the matching.

Once the payment is matched, you post the entry, debiting cash and crediting accounts receivable to clear the balance.

Reconciliation confirms that every invoice is marked paid, partially paid, disputed, or written off. Anything that stays uncollectible after all options are exhausted gets written off, which we'll come back to under bad debt.

6. Manage and improve collections

Days sales outstanding, or DSO, is the number to watch, because it measures how many days on average it takes to collect cash after a credit sale. Calculate it as accounts receivable divided by total credit sales, multiplied by the days in the period, and read a rising DSO as a sign that customers are paying more slowly or that invoicing and follow-up have slipped.

Alongside watching that number, four habits keep cash moving without adding headcount:

• Shorten terms: Use shorter terms where you have negotiating power, especially with customers who have a history of paying late. Every week trimmed off the terms is a week sooner the cash arrives.
• Invoice immediately: Send invoices the day work is delivered so the payment clock starts on time. A week's delay in billing is a week added to DSO before anyone is even late.
• Accept convenient payments: Make it easy to pay by offering the methods customers already use. Friction at the payment step is one of the most common and most fixable causes of slow collections.
• Review aging weekly: Check your aging report before balances drift from mildly late to hard to collect. A quick weekly scan catches problems while a phone call can still fix them.

When these habits stop keeping up with invoice volume, it's usually time to let an automation software take over.

How to record accounts receivable

Every credit sale creates a debit to accounts receivable and a credit to revenue on the income statement at invoicing. When the customer pays, the business reverses the receivable by debiting cash and crediting accounts receivable, which converts AR to cash and leaves revenue unchanged.

The timing is what trips up many operators. Under accrual accounting, revenue and AR show up before the cash does, so a sale can improve the income statement before it improves the bank balance.

In practice, recording a receivable comes down to four steps:

• Issue the invoice: Create the invoice on the day the work is delivered, with the amount, terms, due date, and a unique invoice number.
• Book the sale: Debit accounts receivable and credit revenue for the invoice amount, which records the sale in the period you earned it.
• Apply the payment: When the customer pays, debit cash and credit accounts receivable for the same amount to clear the open invoice.
• Adjust for what won't be collected: At period end, estimate the uncollectible portion, debit bad debt expense, and credit the allowance for doubtful accounts.

Handled consistently, these four entries keep AR reconciled to the general ledger and make the balance sheet figure one you can defend.

Automate your AR processes and reduce late payments

Manual AR is where cash quietly gets stuck. Invoices go out a few days late, follow-ups depend on whoever remembers, and payments arrive without remittance detail, so cash application turns into detective work.

Automation fixes the parts that don't need judgment: invoices generated the day work is delivered, reminders that escalate on their own schedule, payments matched to open invoices automatically, and an aging report that's current.

That leaves your team handling the genuine exceptions, the disputed invoice and the customer who needs a call, rather than the routine chasing.

Modern spend management platforms like Ramp close the other half of the loop by automating bill pay, expense coding, and reconciliation, so the same clean data feeds both sides of your cash cycle.

Frequently asked questions about accounts receivable

Is accounts receivable an asset or a liability?

Accounts receivable is an asset. It sits under current assets on the balance sheet because a business expects to convert it to cash within a year, and the mirror-image liability is accounts payable, which records what the business owes vendors.

Is accounts receivable a debit or a credit?

Accounts receivable carries a normal debit balance, like other asset accounts. A business debits AR when it issues an invoice, which increases the balance, and credits AR when the customer pays or writes the invoice off, which decreases it.

Does accounts receivable count as revenue?

Accounts receivable and revenue are separate records created from the same credit sale. Revenue appears on the income statement when a business earns the sale, while AR is the balance sheet record of the cash it hasn't yet collected.

What is the difference between accounts receivable and accounts payable?

Accounts receivable is money customers owe a business, recorded as a current asset, while accounts payable is money the business owes vendors, recorded as a current liability. A single invoice sits in the seller's AR and the buyer's AP at the same time.

What happens if a customer never pays?

The invoice becomes bad debt. Under GAAP, a business clears it from AR through the allowance for doubtful accounts, and it can also send the invoice to a collections agency, usually once it's 90 or more days overdue. However, the agency keeps part of anything it recovers.
