EU Factur-X PDF
Factur-X / ZUGFeRD 2.x hybrid PDF/A-3 assembly engine
Turn an ordinary invoice PDF into a hybrid PDF/A-3 that carries the EN 16931 UN/CEFACT Cross Industry Invoice (CII) XML as an embedded associated file — the format Germany, France, Belgium, Luxembourg and Austria converge on under the EU ViDA package. Built on the shared e-Invoice Core Engine and the ZUGFeRD/XRechnung profile pack; this module adds the PDF/A-3 conformance layer the standards require.

Genuine PDF/A-3 AFRelationship
The CII XML is embedded with the reserved filename
(factur-x.xml / xrechnung.xml), the
application/xml MIME subtype and
/AFRelationship /Data, wired into both the catalog
/AF associated-files array (PDF 2.0 / PDF/A-3) and the
/EmbeddedFiles name tree, with embedded-file
/Params (ModDate, Size, CheckSum).
XMP conformance packet
A real, well-formed Factur-X / ZUGFeRD XMP RDF packet declares the PDF/A part, the conformance level, the document type and the embedded filename, so a validator detects the profile without parsing the XML.
Full profile ladder
MINIMUM, BASIC WL, BASIC, EN 16931 (COMFORT), EXTENDED and the XRechnung CIUS — each mapped to its canonical GuidelineSpecifiedDocumentContextParameter URN and XMP ConformanceLevel.
Country policy engine
Per Member State minimum profile, default profile, carrier flavour and buyer-reference requirement. A profile too weak for the destination country is blocked — or auto-promoted — before assembly.
Carrier verifier
Re-opens an assembled PDF and proves the /AF array, the
embedded file and the /AFRelationship round-trip correctly —
no blind trust in the writer.
Immutable audit log
A create-only, content-hashed record of every assembly — profile, embedded filename, conformance level and the embedded XML SHA-256 — for archival and audit discipline.
How it works
- Enable Factur-X assembly on the company and pick a default profile via the onboarding wizard.
- On a customer invoice, the engine resolves the effective profile from the buyer country and validates against the matching EN 16931 rule set.
- It builds the CII XML, renders the invoice PDF and assembles a conforming hybrid PDF/A-3.
- Download the hybrid PDF; transport it through your own Peppol / PDP / portal connector (BYOK).
Privacy & transport
This module generates and stores documents on your own database. No invoice data is transmitted anywhere. The official portal endpoints shipped with the country policies are editable defaults and are never called by this engine — transport is bring-your-own-key.
