BR-CO-12
EN 16931-1 layer: en16931
Checked against Peppol BIS Billing 3.0 2026.5
What does BR-CO-12 mean? Sum of charges on document level (BT-108) = Σ Document level charge amount (BT-99).
Why did my invoice fail BR-CO-12?
The document-level total of charges (BT-108) must equal the sum of all individual document-level charge amounts (BT-99). This ensures the header "sum of charges" matches the document-level charge lines so the grand total is arithmetically correct.
Official rule text
Sum of charges on document level (BT-108) = Σ Document level charge amount (BT-99).
Common causes
- A document-level charge omitted from the ChargeTotalAmount.
- Line-level charges wrongly rolled into the document-level charge total.
- Rounding differences between summed charges and the header total.
- ChargeTotalAmount missing or zero while charges are present.
How do I fix it?
Sum all document-level charges into the header: charges of 20.00 and 3.50 give <cac:LegalMonetaryTotal><cbc:ChargeTotalAmount currencyID="EUR">23.50</cbc:ChargeTotalAmount>...</cac:LegalMonetaryTotal>
