NB-PAYMENT-MEANS-UNSUPPORTED — normbill pre-flight check

Card-payment means codes (48/54/55) need card information (BG-18) that normbill cannot express yet — KoSIT would reject the invoice (BR-DE-24-a).

Rule: NB-PAYMENT-MEANS-UNSUPPORTED — normbill pre-flight check (no single official rule id applies)
Severity: error
Business term: BT-81 — Payment means code
Field in your JSON: invoice.payment.means_code

How to fix it

Use a credit-transfer means_code (58 with invoice.payment.iban, or 30) or SEPA direct debit (59 with mandate_id, creditor_id, and debited_iban).

NB-PAYMENT-MEANS-UNSUPPORTED auf Deutsch — was bedeutet der Fehler?

Kartenzahlungs-Codes (means_code 48/54/55) erfordern Karteninformationen (BG-18), die normbill noch nicht abbilden kann — der KoSIT-Validator würde die Rechnung ablehnen (BR-DE-24-a).

So beheben Sie den Fehler

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

NB-* checks run before generation to catch problems the official rule set would only report indirectly. The authoritative KoSIT validation still has the final word on conformance.
