XRechnung error BR-DE-6: seller contact name missing
BR-DE-6 occurs when you have data in the seller contact section (BG-6) but omitted the contact name (BT-41, cbc:Name). Once the contact group is present, the name becomes mandatory.
Last updated: 2026-06-01
Affected field
cac:Contact/cbc:Name (UBL) / ram:DefinedTradeContact/ram:PersonName (CII)
Cause
The invoicing system exported a contact phone or email but left the name field empty or omitted it.
Fix
Add the contact name (e.g. 'Accounts Receivable') to the Contact/Name field. Alternatively, remove the entire contact section if no contact point is needed — the rule only applies when the contact group exists.
<cac:Contact> <cbc:Telephone>+49 30 1234567</cbc:Telephone> </cac:Contact>
<cac:Contact> <cbc:Name>Accounts Receivable</cbc:Name> <cbc:Telephone>+49 30 1234567</cbc:Telephone> </cac:Contact>

Is a seller contact required at all?▼
No. The contact section (BG-6) is optional. The name is only mandatory if you include the contact group. If you don't need to specify a contact, omit the entire Contact element.
Can I use a department name instead of a person's name?▼
Yes. A department name like 'Accounts Receivable' or 'Billing Department' is perfectly valid.
