BR-CO-13 — Invoice total without VAT doesn't add up

What it means

The invoice total without VAT doesn't add up: sum of lines − allowances + charges. The invoice total without VAT (BT-109) must equal the sum of all lines, minus document-level allowances (BT-107), plus document-level charges (BT-108).

How to fix it

Check whether ALL document-level allowances and charges are included in the total calculation (not just line-level ones). A common cause is a document-level allowance (e.g. an overall invoice discount) being added manually but left out of the total formula.

Example

Wrong: line sum 100.00, document allowance 10.00, but the total without VAT is stated as 100.00 (the allowance wasn't subtracted). Correct: total without VAT = 100.00 − 10.00 = 90.00.
