Validation message

The element "Seller contact telephone number" (BT-42) shall be provided.

Explanation

German e-invoicing rules require a phone number for your own contact point — independently of the email address; both are mandatory. A central number is fine; it need not belong to a single person.

How to fix

Add your own phone number to the contact information. Set it once in your company profile and it carries into every invoice.
