Credit & Debit Note Management — Issues the formal corrections — credit notes reversing overcharges, debit notes adding undercharges — with a full audit trail back to the original invoice. Disputes, returns, and SLA credits feed it, and its documents flow through AR and GL posting like invoices.
Credit & Debit Note Management lives in the Rate & Bill phase of Fulfill & Bill — the stage where you activate what was sold, meter what's used, bill it right. In the corpus tool index this phase maps to the Billing and Paymentscategories.
