Accounts receivable aging

An accounts receivable aging lists customer balances by how long they have been outstanding, and auditors use it to select confirmations, test the allowance for credit losses and tie receivables to the ledger.

CORAA TeamUpdated November 5, 2026

Definition

An aging report groups each customer's open invoices into buckets such as current, 1 to 30, 31 to 60, 61 to 90 and over 90 days past due. Its total should equal the accounts receivable control account in the general ledger. Management often applies loss rates to each bucket as part of estimating the allowance for credit losses under ASC 326-20.

Why it matters in an audit or review

The aging is the population for confirmations and for the allowance test. The auditor first checks that it foots, agrees to the ledger and ages invoices from the correct date, since a report built on the wrong date understates old balances. Credits, unapplied cash and disputed items are reviewed because they affect both the aging and the allowance.

Example

Illustrative: receivables of $1,000,000 are current $600,000 at 1%, 1 to 30 past due $200,000 at 3%, 31 to 60 $100,000 at 8%, 61 to 90 $50,000 at 20% and over 90 $50,000 at 50%. The allowance is $6,000 + $6,000 + $8,000 + $10,000 + $25,000 = $55,000, or 5.5% of the balance.

Common mistakes

  • Failing to reconcile the aging total to the ledger before using it.
  • Applying historical loss rates without considering current conditions and forecasts.

    The allowance for credit losses is a valuation account that reduces financial assets to the amount expected to be collected, measured under ASC 326 using lifetime expected losses at inception.
  • Days sales outstanding
    Days sales outstanding measures the average number of days it takes to collect receivables, and auditors use the trend to test receivable existence, cutoff and the adequacy of the allowance.
  • External confirmation
    External confirmation is audit evidence obtained as a direct written response from a third party, on paper or electronically, about a balance, term or transaction, using positive or negative request forms.
  • Subsidiary ledger
