We reply with Factur-X or ZUGFeRD file in ~8 seconds

Three steps. Zero effort.

If you've ever forwarded an email, you already know how to use InvoiceXML.

Forward your Invoice

Simply CC or forward your PDF invoice to [email protected]. That's it—no integration, no software.

AI-Powered Conversion

Our secure engine extracts the data, validates it against 2026 EU standards, and embeds the mandatory XML metadata.

Receive your Compliant File

Within seconds, you'll receive a reply with your new PDF/A-3 Factur-X file attached—ready for the French PPF or German government portals.

Why use the Email Gateway?

Built for teams that don't have time—or budget—for another integration.

Zero Integration

If you can send an email, you're already set up. No plugins, no API keys, no IT department required.

Stateless Privacy

We don't keep your data. We process your invoice in RAM, send the result, and forget the transaction immediately.

2026 Mandate Ready

Every file is checked against official Schematrons for France (Factur-X) and Germany (ZUGFeRD/XRechnung).

Works with Everything

Whether you use Excel, Word, or a 10-year-old accounting system, our email gateway bridges the gap.

Supported E-Invoicing Standards

Our email-to-XML gateway supports the EN 16931 European standard. It is specifically optimized for:

Factur-X (France) - All profiles from Minimum to EXTENDED.

ZUGFeRD (Germany) - Version 2.2 and 2.3.

XRechnung - Validated XML for German B2G (Business-to-Government) transactions.
