Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-17.

## Plain-language reading

The invoice total with VAT (BT-112) must equal the total without VAT (BT-109) plus the VAT total (BT-110). The published test compares them in the document currency and expects one VAT total in that currency.

## What to change

Set BT-112 to BT-109 plus BT-110.
