Credit notes

Vavang Invoice already supports full and partial credit notes created from a frozen source invoice.

Full credit note

A full credit note reuses the immutable fiscal data of the corrected invoice, receives its own number, and keeps an explicit reference to the original invoice number and issue date.

The credit-note number must not be empty and its issue date cannot be earlier than the corrected invoice.

Partial credit note

Partial credit notes explicitly select credited lines and quantities. The plugin reserves and persists allocations so that a quantity cannot be credited beyond what was originally invoiced.

An empty selection, an unknown line or an over-allocation is rejected.

Electronic document

The credit note follows the same compliance pipeline as an invoice: Factur-X generation, structured XML and PDF storage, validation, business journaling and transmission when automatic mode is enabled.

Historical documents remain immutable: a credit note corrects an invoice; it does not rewrite it.
