UBL

UBL (Universal Business Language) is an open XML standard for business documents — invoices, credit notes, orders and more. It is the data format underneath PEPPOL BIS Billing 3.0 and the EN 16931 European standard.

When you send a PEPPOL invoice, Eurobillr generates the UBL XML for you, validates it against the rules, and routes it through a certified Access Point.
