Money clients owe a business for work already delivered but not yet paid — essentially unpaid invoices, counted as an asset.

Accounts receivable (AR) is money your clients owe you for work you’ve already delivered but haven’t been paid for yet. Every unpaid invoice sitting past its send date is part of your AR. It counts as an asset — but it’s not cash until it lands.

For sellers, a growing AR balance is a warning sign, not a badge. It means you’re doing work and not collecting for it, which strangles cash flow. The fixes are prevention (deposits, shorter terms) and follow-through (chasing overdue invoices promptly). For buyers, your unpaid bills are the flip side — the freelancer’s accounts payable — and paying them on time keeps the relationship healthy.

Watch how old your receivables are, not just the total. An invoice at 15 days is normal; one at 75 days is a collection problem that’s quietly becoming a loss. Sorting AR by age tells you who to call first. Our guide on handling late invoices covers the escalation that actually gets you paid.
