What is Accounts Receivable?
Accounts receivable (AR) is the total money owed to your business by clients who have been invoiced but not yet paid — a key measure of your cash flow health.
Definition
Accounts receivable (AR) refers to the total amount of money that clients or customers owe your business for goods or services that have been delivered or rendered but have not yet been paid for. In accounting terms, it is a current asset on your balance sheet — money you have legitimately earned and have the legal right to collect. When you send an invoice, you create an accounts receivable entry. When the client pays, the AR is cleared (reduced to zero) and cash increases. The health of your AR directly affects your cash flow — the longer clients take to pay, the harder it is to fund your own operations.
Understanding Accounts Receivable
Think of accounts receivable as an IOU from your clients. When you complete a project and send an invoice for $5,000, that $5,000 becomes your accounts receivable until the client pays. The invoice creates a legal obligation for the client to pay. If they do not pay within the stated payment terms (e.g., Net-30), the invoice becomes an overdue receivable. AR management is the discipline of ensuring invoices are paid on time — or at least followed up on promptly when they are not. High AR relative to revenue can signal problems: clients are taking too long to pay, payment terms are too loose, or there are disputes over work quality.
Accounts Receivable vs. Accounts Payable
Accounts receivable and accounts payable are mirror images. AR is money owed TO you — you have delivered work and are waiting to be paid. AP is money YOU OWE to others — you have received an invoice and are waiting to pay. Managing both is critical to cash flow. If your AR is healthy (clients paying on time) and your AP is well-managed (paying vendors just-in-time), your business runs smoothly. If clients are slow to pay but you must pay vendors quickly, you face a cash flow crunch. This is why offering reasonable payment terms to clients AND negotiating favorable terms with your own vendors is essential for financial stability.
Managing Accounts Receivable Effectively
Effective AR management involves several practices: send invoices immediately upon completing work — delays in invoicing create delays in payment; set clear payment terms and enforce them consistently; use AR software or accounting tools to track aging invoices (30, 60, 90+ days overdue); send friendly reminders before the due date; follow up promptly when invoices become overdue; consider charging late fees to incentivize on-time payment; and consider requiring deposits or milestone payments for large projects to reduce your AR exposure. The goal is to keep AR days (average collection period) as low as possible — ideally under 30 days for most service businesses.
Key Takeaways
Accounts receivable is an asset on your balance sheet representing money rightfully owed to you. AR and AP are opposite sides of the same coin — managing both is essential for cash flow. A high AR turnover ratio (collections relative to outstanding balance) indicates healthy collections. Prompt invoicing, clear terms, and consistent follow-up are the foundations of AR management.
