Why UBL and Peppol Compliance Matter
UBL 2.1 is the XML backbone of the Peppol network — the global infrastructure connecting millions of businesses and government entities. Peppol BIS Billing 3.0 mandates UBL 2.1 as its invoice format and is required for public sector invoicing in Norway, Denmark, Sweden, Singapore, Australia, and New Zealand. With Peppol adoption expanding rapidly across the EU and beyond, converting your PDF invoices to UBL ensures you can reach any buyer on the network — without manual data entry or format conversion at the other end.
Frequently Asked Questions
What is UBL?
UBL (Universal Business Language) is an OASIS XML standard for electronic business documents. UBL 2.1 is one of the two official syntaxes of the European EN 16931 e-invoicing standard and is the native format of the Peppol network.
What is Peppol and why does it matter?
Peppol (Pan-European Public Procurement On-Line) is a global network for exchanging e-invoices. It is mandatory for public sector invoicing in Norway, Denmark, Sweden, Singapore, Australia, and New Zealand, and is increasingly adopted for B2B in the Netherlands, Belgium, Italy, and more.
How does UBL differ from CII?
Both UBL and CII are valid EN 16931 syntaxes. UBL 2.1 is used by Peppol BIS Billing 3.0 and is the dominant format on the Peppol network. CII is used by ZUGFeRD and Factur-X. Use UBL when your recipients or network is Peppol-based.
Is the output Peppol BIS Billing 3.0 compliant?
Yes. Our converter generates UBL 2.1 invoices that conform to the Peppol BIS Billing 3.0 specification, validated against both EN 16931 and Peppol-specific business rules.
