Rule reference

BR-CO-16 BR-CO-16 requires the amount due for payment (BT-115) to equal BT-112 − paid amount (BT-113) + rounding amount (BT-114)

BR-CO-16 requires the amount due for payment (BT-115) to equal BT-112 − paid amount (BT-113) + rounding amount (BT-114). You declared 1.00 for BT-115, but the invoice lines compute to 1785.00 — a difference of -1784.00 EUR. This version of the library does not yet model prepaid or rounding amounts, so BT-115 must equal BT-112.

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.payableAmount 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.
