Age alone does not explain what happens next.

An AR ageing report groups open customer invoices by the time they have remained unpaid. Common buckets are current, 1–30, 31–60, 61–90 and more than 90 days overdue. The report shows concentration and timing, but the invoice record is still needed to explain disputes, payment evidence, ownership and the next action.

Days sales outstanding, or DSO, estimates how long a business takes to collect credit sales over a defined period. A common calculation divides average accounts receivable by credit sales and multiplies by the number of days. Use consistent inputs and periods; seasonality, billing mix and large invoices can materially change interpretation.

No. Age is important, but amount, customer response, dispute status, payment evidence, commitment date and strategic context can change priority. A paid invoice awaiting a match belongs in reconciliation, while a younger material dispute may require immediate ownership. The useful queue combines age with the operational state and assigned owner.

Ageing shows how long balances have remained open; it does not by itself predict payment or provide credit-risk scoring. Historical behaviour may inform an organisation’s judgement, but the page does not claim automated risk models. Use the report as an operational signal and retain the evidence behind any separate credit decision.

An invoice can remain open when payment has arrived but has not yet been matched to the correct record, amount or customer. The ageing view should therefore connect to reconciliation status. Once the payment is verified and applied, the resolved balance should leave the open-receivables population according to the organisation’s process.
