BR-CO-15 — Invoice total with VAT doesn't add up

What it means

Invoice total with VAT (BT-112) doesn't equal the total without VAT (BT-109) plus the total VAT amount (BT-110) — the validator checks that these three fields add up, and the check fails.

How to fix it

Verify that BT-112 actually equals BT-109 + BT-110. The most common cause is rounding: EN 16931 requires amounts to be rounded at the VAT-rate level (after summing per rate), not per line. If the invoice was produced by accounting software (Jumis, Horizon, 1C, etc.), check its VAT calculation and rounding settings, or ask the vendor.

Example

Wrong: BT-109 = 100.00, BT-110 = 21.00, BT-112 = 120.99 (doesn't match). Correct: BT-109 = 100.00, BT-110 = 21.00, BT-112 = 121.00.
