The amount due including VAT does not match the net total plus VAT

The total amount including VAT (BT-112) must be exactly the net total (BT-109) plus the total VAT amount (BT-110).

A financial field: the expected value is computed and offered, never written into the document — the correction is the issuer's to make. Test your invoice to find out whether it is affected.

Why this error happens

This is the most frequent arithmetic inconsistency, and it almost always comes from rounding applied line by line instead of on the total, or from an invoice-level discount left out of one of the two terms. A one-cent gap is enough to trigger the check.

How to fix it

Fix the calculation in the system that produced the invoice, not in the file. Factlint computes the expected value and returns it in `suggested_value`, but never writes the field.
