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.
The message your validator prints
Copied verbatim from the sealed artefact: this is the exact sentence the check prints when this rule fails.
[BR-CO-15]-Invoice total amount with VAT (BT-112) = Invoice total amount without VAT (BT-109) + Invoice total VAT amount (BT-110).

Test your file with this error in mind
Upload the invoice involved: the report will say whether this code appears, where it appears in the document, and whether Factlint can only report it or also fix it.
To automate this check in an ERP flow, call the validation API and link every returned code to its public page.
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.
