Accounts receivable is money a business is owed by customers who bought on credit

When a business sells something but doesn't get paid right away, that unpaid amount becomes accounts receivable. Think of it as a promise from a customer to pay later. A plumbing company that fixes your pipes and sends you a bill at the end of the month has accounts receivable until you pay that bill. A wholesale supplier that ships products to a store with payment due in 30 days has accounts receivable for those 30 days.

Accounts receivable is not the same as cash in the bank. It is a claim on future cash — money the business expects to receive but hasn't yet. This matters because a business can look profitable on paper while running out of actual money if too many customers owe them too much for too long.

Key Takeaways

  • Accounts receivable is the total amount customers owe a business for goods or services already delivered.
  • It appears on a business's balance sheet as an asset because it represents money expected to come in.
  • Businesses track accounts receivable to know how much cash will arrive and when, which affects their ability to pay their own bills.
  • If a customer never pays, the business writes off that amount as a bad debt loss.

How accounts receivable appears on a business's financial records

When you look at a company's balance sheet — the financial statement that shows what a business owns and owes — accounts receivable sits on the asset side. Assets are things of value. Money owed to you is valuable because you expect to collect it.

The business records each sale on credit as a transaction. If a customer buys $500 worth of goods and promises to pay in two weeks, the company records $500 in accounts receivable that day, even though the cash hasn't arrived. This is called accrual accounting — recording the sale when it happens, not when the money shows up.

As customers pay their bills, the accounts receivable number goes down and the cash number goes up. If a customer never pays, the business eventually removes that amount from accounts receivable and records it as a loss.

Why businesses care about how long customers take to pay

A business needs cash to operate. It pays employees, buys supplies, and covers rent whether or not customers have paid yet. If a company sells $100,000 worth of products but customers don't pay for 90 days, the business might run out of money before those payments arrive.

Businesses track something called days sales outstanding (DSO), which measures how many days it takes on average for customers to pay. A business with a DSO of 30 days collects payment roughly one month after a sale. A DSO of 60 days means customers take two months. The longer the DSO, the more cash the business has tied up waiting for payment.

This is why businesses sometimes offer discounts for early payment — a 2% discount if you pay in 10 days instead of 30. The discount costs them money, but getting cash sooner can be worth it.

The difference between accounts receivable and other money owed to a business

Accounts receivable specifically means money owed for goods or services the business has already delivered. It does not include deposits customers paid upfront, refunds the business owes, or loans the business made to someone.

A gym that collects membership fees in advance has cash, not accounts receivable. A contractor who collects a 50% deposit before starting work has cash. Once the contractor finishes and bills for the remaining 50%, that remaining 50% becomes accounts receivable.

Some businesses also track accounts payable, which is the opposite — money the business owes to its suppliers. Accounts receivable is what customers owe you. Accounts payable is what you owe others.

What happens when customers don't pay

Not every customer pays on time, and some never pay at all. Businesses handle this in stages. First, they send reminders — a past-due notice, a phone call, or an email. If the customer still doesn't pay after 30, 60, or 90 days, the business may hire a collection agency or pursue legal action.

If it becomes clear a customer will never pay, the business writes off the debt. This means removing it from accounts receivable and recording it as a loss on the income statement. The business gets no tax deduction for the loss unless it is a bad debt the business previously reported as income — which is why businesses that use accrual accounting track bad debts carefully.

Some businesses set aside money called an allowance for doubtful accounts or bad debt reserve. This is an estimate of how much accounts receivable will never be collected, based on past experience. If a business knows from history that 2% of its sales on credit never get paid, it reserves 2% of current accounts receivable as a buffer.

How small businesses and large companies handle accounts receivable differently

A small business with five customers might track accounts receivable in a spreadsheet — a straightforward list of who owes what and when payment is due. A large company with thousands of customers uses accounting software or an entire department to manage it.

Large companies often use a process called factoring, where they sell their accounts receivable to a third party (called a factor) at a discount. If a company is owed $100,000 but needs cash now, it might sell that receivable to a factor for $95,000. The factor then collects the full $100,000 from the customer and keeps the $5,000 difference as profit. The company gets cash when ready instead of waiting.

Small businesses rarely use factoring because the discount is expensive, but it can be necessary when cash flow is tight and waiting for customer payments would force the business to shut down.

Accounts receivable and business health

The amount of accounts receivable a business carries tells you something about how well it is managing cash. A business with growing accounts receivable might be selling more, which sounds good — but only if customers are actually paying. If accounts receivable grows much faster than sales, it means customers are taking longer to pay or the business is extending credit to riskier customers.

Investors and lenders look at accounts receivable when deciding whether to invest in or lend money to a business. A company with $1 million in sales and $500,000 in accounts receivable is waiting for half its revenue to arrive. A company with $1 million in sales and $50,000 in accounts receivable collects cash much faster and is generally in better financial health.

Frequently Asked Questions

Is accounts receivable the same as revenue?

No. Revenue is the total amount a business sold, whether paid or not. Accounts receivable is only the portion of revenue that customers haven't paid yet. A business can have high revenue but low accounts receivable if customers pay when ready, or high revenue and high accounts receivable if customers pay slowly.

Can accounts receivable be negative?

Not in the normal sense. Accounts receivable is a list of what customers owe, so it cannot be negative. However, if a customer overpays or the business owes them a refund, that amount might appear as a negative line item or be tracked separately as a customer credit or deposit liability.

What does it mean if a business has very high accounts receivable?

It could mean the business is growing and selling more on credit, which is normal. It could also mean customers are paying slowly, the business extended credit to customers who are struggling to pay, or the business is not collecting aggressively. High accounts receivable ties up cash and increases the risk that some money will never be collected.

Do I need to understand accounts receivable if I'm starting a small business?

Yes, especially if you plan to sell on credit. Knowing how much customers owe you and when they will pay helps you predict whether you will have enough cash to cover expenses. Many small businesses fail not because they are unprofitable, but because they run out of cash waiting for customer payments.
