Peppol BIS vs local CIUS profiles

Peppol BIS Billing 3.0 is itself a CIUS of EN 16931 and suffices in most Peppol countries. Some jurisdictions add their own CIUS with extra rules — XRechnung (DE B2G), NLCIUS (NL), CIUS-PT (PT), e-SLOG (SI) — which applies on top when invoicing those scenarios.

Decision rule of thumb

1. Receiver in a Peppol-first country, B2B → Peppol BIS is the answer (BE, NO, SE, DK, FI, IS, NL mostly, AT, IE…).
2. B2G with a national CIUS → use it (XRechnung in Germany, CIUS-PT in Portugal, FacturaE in Spain’s FACe).
3. Clearance country → the national format rules domestically (FatturaPA, FA(3), RO_CIUS) and Peppol BIS covers cross-border.
4. Outside Europe → the local PINT profile applies.

Your provider should pick the right profile from the receiver’s SMP entry and destination country automatically — that is exactly what the country pages’ “formats” sections document per market.
