Invoicing

Credit and replace an issued invoice

Creates a separately numbered full credit note and an unsent editable replacement draft. A queued e-invoice with no provider attempt is cancelled before transmission: its queue evidence becomes terminal and its credit note stays internal. A finalized PDF credit is not transmitted. An accepted e-invoice credit uses the original Maventa connection. The original and credit note remain in history. Supported for own-name invoices before any earlier credit. Replay-safe per original invoice. Requires a write-scoped key.
