Peppol BIS 3.0 WARNING

The official rule text below states the exact requirement your invoice does not meet. The referenced business terms (BT-xx) identify the fields involved.

How to fix it
  1. Locate the elements for the business terms (BT) named in the rule text.
  2. Compare your values against the stated requirement and correct them.
  3. Re-validate - fixing one rule sometimes reveals a related one.
Official rule text
"Seller contact email address" (BT-43) should contain exactly one @-sign, which should not be framed by a whitespace or a dot but by at least two characters on each side. A dot should not be the first or last character.

Developers also reach this page searching for a “Peppol invoice error”, an “e-invoice rejected by access point” message, or how to resolve a failed Peppol BIS 3.0 check — it's the same issue, explained above.
