BR-CO-16: The amount due does not match the invoice total. How to fix it
The amount due (BT-115) does not equal the gross total minus what has already been paid, plus rounding.
Error: the invoice is refusedFrom the European norm EN 16931
The rule, in its own words
Amount due for payment (BT-115) = Invoice total amount with VAT (BT-112) -Paid amount (BT-113) +Rounding amount (BT-114).
Fields involved: BT-115, BT-112, BT-113, BT-114
What the rule checks
The rule works out the amount due: the gross total, less any prepayment already made, plus a rounding amount. This too is checked to the cent.
Why files fail it
- A prepayment was deducted from the amount due but not recorded in the field meant for it, "paid amount" (BT-113).
- The amount due was typed by hand while the other totals were calculated.
- An early-payment discount has already been deducted. That belongs in the payment terms, not in the amount due.
- A rounding amount was applied without being declared in BT-114.
How to fix it
- If a prepayment was made, put it in the "paid amount" field (BT-113) rather than silently subtracting it.
- Do not deduct an early-payment discount from the amount due. It belongs in the payment terms as text; the amount due is the figure before any such discount.
- Let the amount due be calculated rather than overwriting it.
- With no prepayment and no rounding the rule is simply: amount due equals the gross total.
