This validator checks the file structure and basic invoice consistency. It is not a legal certification tool and does not replace formal external conformance testing.

What it checks

A thin validator for quick structural triage before deeper processing.

Embedded XML detection inside ZUGFeRD-style PDFs

XML well-formedness and supported invoice root elements

Profile recognition across ZUGFeRD/Factur-X (MINIMUM, BASIC WL, BASIC, EN 16931, EXTENDED) and XRechnung

Presence of core invoice fields needed for normalization

Basic subtotal + tax = total consistency checks

PDF/A-3 style packaging markers when relevant

Upload a candidate ZUGFeRD PDF or XRechnung/XML file to inspect its structure, invoice profile hints, and core consistency checks.

Beyond the validator

The real workflow starts after the file passes.

NameQuick Invoices takes the same messy mix of PDFs, scans, XRechnung, and ZUGFeRD files, extracts the right fields, pushes uncertain documents into review, and exports cleanly for DATEV-ready export.
