Understand the scope
Definition and points to distinguish
For customers, it must be specified whether ageing is calculated from the invoice date or its due date. The brackets are presentation choices; they do not replace statutory or contractual deadlines. Payments, credit notes and disputes must be reconciled before delays are interpreted.

What this changes in practice
The aged trial balance categorises receivables or payables according to their due date in order to identify delays. It must be based on reliable dates and matching. An old amount may correspond to an unpaid debt, a dispute or a posting error: it requires verification. The tool is used for debt collection and cash management, as well as for assessing the risk of non-recovery.

The practical question

Pourquoi une facture ancienne peut-elle rester dans la balance âgée après paiement ?
Le règlement peut être enregistré sur un mauvais compte, non lettré ou affecté à une autre facture. Vérifiez les références avant de relancer le client. La balance âgée doit donc être nettoyée des erreurs de rapprochement pour devenir un outil fiable. Elle aide ensuite à distinguer les vrais retards des litiges et problèmes d’enregistrement.
