BR-06: Your own company name is missing. How to fix it

The invoice does not name the seller (BT-27).

Error: the invoice is refusedFrom the European norm EN 16931

The rule, in its own words

An Invoice shall contain the Seller name (BT-27).

Fields involved: BT-27

What the rule checks

The rule checks that the seller's name is present and not empty. It means your registered company name, not an abbreviation and not a brand name.

Why files fail it

  • The field is there but blank. For the check, an empty field is the same as a missing one.
  • The company name appears only on the PDF letterhead, not in the structured data.
  • The invoice came from a template where the sender field was still a placeholder.

How to fix it

  1. Enter your full company name as it is registered.
  2. The field is "Seller name" (BT-27) in the standard; in invoicing software it is part of your own master data.
  3. Check that the name really is in the data and not only in the letterhead layout.
