Why use an e-invoice viewer?
Structured e-invoicing requirements keep growing. XRechnung, ZUGFeRD, and Factur-X follow EN 16931. Yet teams often need a quick way to inspect what is actually inside a file.
Our free viewer helps finance, procurement, and IT understand incoming files: detect the format, check key fields, and review line items, with no software install.
Jupiter ERP creates ZUGFeRD 2.x invoices directly in the panel. If you want to issue compliant e-invoices, not just read them, start free in the app.
Frequently asked questions
- Which formats are supported?
- The viewer supports XRechnung (CII XML), ZUGFeRD and Factur-X PDFs with embedded XML, and UBL/Peppol invoices. Common extensions: .xml, .xrechnung, and .pdf.
- Are my files uploaded to a server?
- Yes. Your file is transferred securely for analysis, evaluated, and then discarded. No account is required.
- Is this an official XRechnung validation?
- No. The viewer checks structure and important mandatory fields as a plausibility check. Official Schematron conformance testing requires specialized validation software.
- What is EN 16931?
- EN 16931 is the European standard for electronic invoices. XRechnung, ZUGFeRD, and Factur-X build on it and define which fields must be present.
