NO-R-002
Peppol BIS Billing 3.0.21For Norwegian suppliers, most invoice issuers are required to append "Foretaksregisteret" to their invoice. "Dersom selger er aksjeselskap, allmennaksjeselskap eller filial av utenlandsk selskap skal også ordet «Foretaksregisteret» fremgå av salgsdokumentet, jf. foretaksregisterloven § 10-2."
This rule has no plain-English explanation of our own yet. The official text above is exact.
A warning does not make the document invalid. Receivers may still act on it, so it is worth fixing.
