BR-DE-1

The invoice must contain payment instructions (group BG-16) — at minimum, how the invoice is meant to be paid.

Severity: Error
Applies to: CII, UBL
Rule set: v2026-01-31

Official rule text

Eine Rechnung (INVOICE) muss Angaben zu "PAYMENT INSTRUCTIONS" (BG-16) enthalten.

Why it happens

Many systems print bank details only in the footer of the PDF. They are visible to a human but entirely absent from the structured data.

How to fix it

Populate BG-16 as structured data: payment means code (BT-81) and, depending on the method, the account details such as IBAN in BT-84. Free text in the footer does not count.
