BR-CO-16 — Amount due for payment doesn't add up

What it means

The amount due for payment doesn't add up: total with VAT − prepaid amount

• rounding. The amount due (BT-115) must equal the total with VAT (BT-112) minus the amount already paid (BT-113) plus the rounding amount (BT-114).

How to fix it

Check that the amount due really equals the total with VAT minus any prepaid amount plus rounding. If the invoice has no prepayment or rounding, these fields should be 0, not empty — some software drops them entirely, which can trigger this error.

Example

Wrong: total with VAT 121.00, prepaid 21.00, but the amount due is stated as 121.00 (the prepayment wasn't subtracted). Correct: amount due = 121.00 − 21.00 = 100.00.
