CII

What is CII (Cross Industry Invoice)?

⚠ Machine-translated answer, not yet manually reviewed. For the exact wording, see the Slovak original.

Short answer

CII (Cross Industry Invoice) is an international XML standard developed by the UN/CEFACT organization. Like UBL, it represents one of the official syntaxes supported by the EN 16931 standard — an electronic invoice according to EN 16931 can be written either in UBL or in CII, if it meets the requirements of the standard.

UN/CEFACT standard

Not OASIS like UBL

CII is developed by an international organization other than UBL.

Same content

Another XML structure

CII writes the same Business Terms EN 16931 in a different syntax.

Not for Peppol BIS

UBL is the standard of the Peppol network

Peppol BIS Billing 3.0 uses UBL, not CII.

EDIFACT bridge

CEN/TS 16931-3-4

The document describes the mapping from EDIFACT via EN 16931 to UBL or CII.

Conclusion

CII is a full-featured but not used syntactic implementation of EN 16931 in the Peppol BIS Billing network — Peppol requires UBL.
