Rule reference

BR-CO-13 BR-CO-13 requires the invoice total without VAT (BT-109) to equal Σ BT-131 − document allowances (BT-107) + document charges (BT-108)

BR-CO-13 requires the invoice total without VAT (BT-109) to equal Σ BT-131 − document allowances (BT-107) + document charges (BT-108). You declared 1.00 for BT-109, but the invoice lines compute to 1500.00 — a difference of -1499.00 EUR. This version of the library does not yet model document-level allowances or charges, so BT-109 must equal BT-106 exactly.

This rule is implemented and its error payload below is real, but the long-form write-up — normative text, worked example, divergence note — is not written yet. Everything the library knows about this rule is on this page. Ask and we will prioritise it.

The fix

Either correct the line data so it sums to your declared figure, or drop declaredTotals.taxExclusiveAmount and let the library compute it. Note that EN 16931 sums *rounded* line amounts: round each line to 2 decimals first, then add — rounding only the final sum drifts by a cent or two on long invoices.
