Main features include: - PDF invoice to XRechnung conversion - PDF invoice to ZUGFeRD conversion - XRechnung XML validation - ZUGFeRD PDF validation with embedded XML - Readable display of structured invoice data - Support for EN 16931, XRechnung and ZUGFeRD workflows - Web-based usage without local installation - Lightweight workflow for individual invoices rather than a full accounting suite
