Accounts receivable aging

Also called: A/R aging, aged receivables, receivables aging
You might ask
“Which customers still owe us money, and how late are their invoices?”
Direct answer

A report that groups unpaid customer balances by how long invoices have remained current or overdue. Each guide connects the definition to a finance workflow and the source records you should verify.

The sample is illustrative. Use the same structure with your own reporting period and source records.

What it tells you

An accounts receivable aging report organizes outstanding customer balances into time periods. Common buckets are current, 1-30 days past due, 31-60 days, 61-90 days, and more than 90 days.

The summary view shows balances by customer and aging period. A detail view shows the invoices or other transactions behind those balances.

Why aging matters

Two businesses can have the same total receivables but very different collection risk. A balance concentrated in current invoices is different from one concentrated beyond 90 days.

The report helps a reviewer prioritize collection work, spot customer concentration, and identify whether older receivables are increasing.

What to verify first

Check the report date, aging method, period length, and whether credits or unapplied payments are included. Compare the summary total with the accounts receivable balance in the general ledger or balance sheet.

Common mistake

Age alone does not prove that an invoice is collectible or uncollectible. Disputes, duplicate invoices, incorrect due dates, credit memos, and unapplied payments require transaction-level review.
