How this service works
Transforms JSON invoice payloads in-RAM into schema-valid Peppol BIS Billing 3.0 UBL 2.1 XML.
Output
A schema-valid Peppol BIS Billing 3.0 UBL 2.1 XML document serialized from the provided JSON invoice payload, produced entirely in-memory with no external storage side effects.
Example use cases
EU supplier e-invoice submission
“I need to send an electronic invoice to my German buyer — can you convert this invoice JSON into a Peppol BIS Billing 3.0 UBL 2.1 XML so I can submit it through the Peppol network?”
Automated billing pipeline XML generation
“Our billing system outputs invoice data as JSON objects — transform this one into a valid UBL 2.1 XML e-invoice so we can pass it downstream to our Peppol access point.”
E-invoicing compliance check before dispatch
“Before we send this invoice to the government procurement portal, can you turn the JSON payload into a schema-valid Peppol BIS 3.0 XML and confirm it passes the UBL structure requirements?”

- Malformed JSON body or incorrect bodyType enum value results in a parse error
- Invoice amounts or tax calculations that violate UBL business rules trigger a compliance rejection
- Unsupported Peppol profile extensions in the input may produce an incomplete or invalid XML output
- Network timeout or service unavailability returns a 5xx error with no XML output
