BR-DE-24-a — XRechnung rule

The payment means is a card payment (code 48, 54 or 55), so card information (BG-18) is required.

Rule: BR-DE-24-a — official EN 16931 / XRechnung rule
Severity: error
Business term: BT-81 — Payment means code
Field in your JSON: invoice.payment.means_code
Detected by: tier 1 — normbill pre-flight (also in the playground)
Reachability: Triggerable from your request JSON (generate & validate)

Tier 1 rejects card payment means codes up front (NB-PAYMENT-MEANS-UNSUPPORTED) because the model has no card information (BG-18) to satisfy this rule.

How to fix it

normbill cannot express card information — use a credit-transfer means_code (58 with an IBAN, or 30), or SEPA direct debit (59 with mandate_id, creditor_id, and debited_iban).

BR-DE-24-a auf Deutsch — was bedeutet der Fehler?

Als Zahlungsart ist eine Kartenzahlung (Code 48, 54 oder 55) angegeben, dann sind Karteninformationen (BG-18) Pflicht. normbill kann Karteninformationen nicht abbilden und weist diese Codes bereits vorab zurück.

So beheben Sie den Fehler

Verwenden Sie eine Überweisung (means_code 58 mit IBAN oder 30) oder SEPA-Lastschrift (59 mit mandate_id, creditor_id und debited_iban).
