BR-DE-5

A seller contact point (BT-41) must be transmitted — a person or department the buyer can turn to.

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

Official rule text

Das Element "Seller contact point" (BT-41) muss übermittelt werden.

Why it happens

The field simply does not exist in many invoicing systems; only company name and address are captured. On export BT-41 stays empty even though BG-6 is present.

How to fix it

Send a person or department, such as "Accounting" or "Jane Doe": cac:Contact/cbc:Name in UBL, ram:DefinedTradeContact/ram:PersonName or ram:DepartmentName in CII.
