View and check ZUGFeRD and XRechnung. Read electronic invoices and check text matches for invoice values in hybrid ZUGFeRD files. The automatic comparison searches extractable invoice text for structured values, showing matches and values not found. Factur-X and Peppol BIS Billing 3.0 are also supported.

A green tick with a defined meaning. The green tick for the technical check means “No errors within the scope checked”. Text matching is a separate result; even a 100% match rate does not prove complete content or visual agreement. Technical checks use XML schemas and official EN 16931/XRechnung rules. The result does not constitute approval for tax purposes. This is not a certified validator or a substitute for tax or legal advice.

For incoming invoices. Open .eml and .msg files or bring invoices in from Outlook. The trial and full version provide an add-in for classic Outlook, a local HTTP API and a command-line interface. Email drafts in all 24 official EU languages help you prepare queries to invoice issuers. Viewing and checks run locally and offline; licensing, registration and updates require internet access. A4 printouts and PDF exports of the rendering do not replace the original file.
