Peppol BIS Billing 3.0, May 2026 release, EN 16931 model bound to UBL

Severity note: fatal, from the Flag column of the Peppol BIS Billing 3.0 UBL rules index retrieved 2026-10-18.

## Plain-language reading

The amount due for payment (BT-115) must equal the invoice total with VAT (BT-112) minus the paid amount (BT-113) plus the rounding amount (BT-114). The statement has no space in -Paid or +Rounding, and it ends with a period. The published test covers a missing paid amount and a missing rounding amount. Both the present branch and the absent branch call exists.

## What to change

Set BT-115 to BT-112 minus BT-113 plus BT-114. Leave out a paid amount or a rounding amount only when that element is absent.

## Illustration

Illustration of the condition in the official statement. Not an example published by the source.

**Fails the stated condition.** BT-112 is 119, the paid amount is 19, there is no rounding amount, and BT-115 is 119.

**Passes the stated condition.** Those same amounts, and BT-115 is 100.
