Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.
An invoice must have the invoice total amount without VAT (BT-109). The message says "shall have the". The published test checks that cbc:TaxExclusiveAmount exists. It does not calculate that amount from line nets, allowances, or charges.
Add cbc:TaxExclusiveAmount on the legal monetary total. That element is the invoice total amount without VAT (BT-109).
Illustration of the condition in the official statement. Not an example published by the source.
Fails the stated condition. The legal monetary total has no tax exclusive amount.
Passes the stated condition. The legal monetary total has a tax exclusive amount element.
