BR-CO-25

Whenever the amount due for payment (BT-115) is positive, the invoice must carry either a payment due date (BT-9) or payment terms (BT-20).

Severity: Error
Applies to: CII, UBL
Rule set: v2026-01-31

Official rule text

In case the Amount due for payment (BT-115) is positive, either the Payment due date (BT-9) or the Payment terms (BT-20) shall be present.

Why it happens

In many systems the payment deadline exists only as footer text on the PDF. Both structured fields are then empty even though the information is available.

How to fix it

Send the due date in BT-9 (cbc:DueDate in UBL, ram:DueDateDateTime in CII) or the payment terms as text in BT-20, for example "Payable within 14 days net".
