Frequently Asked Questions

What is UN/CEFACT CII?

CII (Cross-Industry Invoice) is a UN/CEFACT XML standard for electronic invoicing. It provides a rich, internationally recognized data format used as the XML syntax for ZUGFeRD, Factur-X, and many national e-invoicing implementations.

How does CII differ from UBL?

Both CII and UBL are accepted syntaxes under the European Norm EN 16931. CII is the syntax used by ZUGFeRD/Factur-X, while UBL is common in Peppol. Our converter produces CII XML, which can be embedded in PDF or transmitted standalone.

Can I use CII XML without a PDF wrapper?

Yes. While we can produce a PDF/A-3 with embedded CII XML, we also support generating standalone CII XML files for direct integration with ERP systems or e-invoicing networks.

Is CII suitable for international invoicing?

Absolutely. As a UN standard, CII is designed for cross-border trade. It supports multi-currency, international tax schemes, and is recognized by customs and trade authorities worldwide.
