An XML file is not a readable invoice view.
German businesses have needed to receive e-invoices since 2025. Yet an XML file is not something you can skim like a letter. Klarbeleg turns structured data into an invoice view and reviews selected fields, formats and totals.
For ZUGFeRD and Factur-X, the embedded XML is extracted from the PDF. The visible PDF is not checked. Keep your original file: this view and the CSV export replace neither the invoice nor proper record retention.
Batch review for accountants & bookkeepers — planned
Many invoices, the same review routine. We want to know whether a combined review and a clear issue report would help your team. Register for updates on the planned batch tool.
