Accounts receivable is the amount customers owe a business for goods or services already supplied on credit. The AR process includes issuing invoices, recording receipts, applying payments, following up overdue balances, and resolving deductions or disputes.

Review points before the transaction moves

  • Confirm the party responsible for the transaction record.
  • Keep the source data and approval with the transaction.
  • Record exceptions instead of silently changing the original instruction.
  • Make the downstream owner able to reconstruct what happened without an email search.

The boundary worth keeping clear

The definition matters because nearby terms can describe a different document, event or responsibility. Use Accounts receivable (AR) only when the record matches the conditions above. A familiar label attached to the wrong stage creates cleaner-looking data and worse decisions. That discipline also makes reports comparable across teams, systems and reporting periods.

Related terms and distinctions

  • Invoice: An invoice is a document a seller issues to request payment for supplied goods or services.
  • Order-to-cash (O2C): Order-to-cash is the process from accepting a customer order through fulfilment, invoicing, payment collection, and reconciliation.

The trade-off

More controls add work at the start. That cost is visible. The cost of weak records arrives later as rework, delayed approval, margin leakage, a payment investigation or a delivery dispute. Set the control depth according to the amount, risk and reversibility of the decision.
