Credit Note / Corrected Invoice

Definition

A credit note or corrected invoice is issued when an original invoice was erroneous or a supply is reversed. In EN 16931, a credit note is identified with invoice type code 381 and a corrected invoice with code 384. The corrective invoice typically contains the original invoice number as a reference (BT-25) and must include all mandatory fields just like a regular invoice.
