ZUGFeRD Validator

The tool processes ZUGFeRD invoices (XML or ZIP) and verifies conformance to recognized profiles such as BASIC, COMFORT, or EN 16931. It performs schema validation, mandatory element checks, and profile-specific constraints to ensure machine-readable data is complete and accurate.
Conceptually, validation occurs by parsing the invoice, applying profile rules, and producing a structured report that highlights deviations with precise locations. This supports predictable downstream processing in ERP and procurement systems.
Who benefits: accounts payable teams seeking faster onboarding, developers building automated invoice pipelines, and auditors validating supplier data quality. The tool's value lies in early error detection, repeatable checks, and automation-ready outputs.
Core features include file input support, selectable profiles, deterministic error codes, and export options for JSON or XML. Optional enhancements cover batch processing, custom rule sets, and integration hooks for CI workflows. Use cases cover pre-submission validation, bulk supplier validation, and compliance auditing across finance departments.
