Seller contact email address is missing

BR-DE-7 comes from the official e-invoicing rule sets. This page explains what the rule checks, why invoices trip over it and the concrete change that makes the document pass.

Applies to: XRechnung

Related fields: BT-43

Why this error appears

Part of the XRechnung seller contact requirement: the contact email address (BT-43) completes the trio with name and phone. All three must be present at the same time, fixing them one by one produces three validation rounds instead of one.

How to fix it

Provide the seller contact email address (BT-43).

Example

Rejected

<cac:Contact>
  <cbc:Name>Rechnungsstelle</cbc:Name>
  <cbc:Telephone>+49 30 1234567</cbc:Telephone>
</cac:Contact>

  <cbc:Name>Rechnungsstelle</cbc:Name>
