Most accounting and procurement systems still receive supplier invoices as PDFs, but e-invoicing mandates across Europe (Belgium, the Netherlands, Poland, the Nordics) increasingly require structured UBL or Peppol BIS Billing 3.0 XML. Manual rekeying is slow, error-prone, and does not scale. This converter bridges that gap: drop a PDF and get validated UBL back.
What the PDF to UBL converter does
Conversion runs in three stages, all automatic:
AI extraction - the engine reads your invoice whether it is a native (digital) PDF or a scan, in most European languages and any layout. It identifies the seller and buyer, line items, tax breakdown, totals, and payment details without templates or rules to maintain.
EN 16931 mapping - extracted data is mapped onto the UBL 2.1 syntax with the correct elements, cardinality, and code lists: UN/ECE unit codes, VAT category codes, and the document and tax structures the European standard expects.
Peppol BIS 3.0 validation - before you download, the output is validated against the UBL 2.1 schema, the EN 16931 business rules, and the Peppol BIS Billing 3.0 CIUS, so what you get is ready to send over a Peppol Access Point.
Review before you send
AI extraction is fast but not infallible. Any field the engine could not read with confidence, or a Peppol-required value the PDF did not contain (commonly the seller or buyer electronic address), is highlighted for review so you can correct it before export rather than after a rejection.
Privacy is built in: PDFs and the generated UBL are processed in-memory and discarded the moment your file is ready. Nothing is stored on our servers, shared with third parties, or used for model training.
