Detect and verify electronic invoices in your email attachments directly within Gmail™, without having to download them or open external programs. E-Invoice Preview extracts the invoice data and presents the most important information clearly in the sidebar.

Your benefits at a glance:

- Quick overview: Instantly see the seller, invoice amount, currency, and individual line items at a glance.
- Comprehensive format support: Compatible with common EN 16931 standards, including ZUGFeRD, Factur-X, XRechnung, Peppol BIS Billing, and ebInterface 6.x.
- Transparency for hybrid formats: For ZUGFeRD/Factur-X PDF files, the add-on extracts the XML file embedded in the document and makes the structured data visible.

Maximum privacy (100% Client-Side):

The processing of your sensitive invoice data takes place entirely locally within your browser. No server upload is required, and no invoice data is transmitted to external servers.

How it works:

- Open an email containing an e-invoice attachment.
- Click the E-Invoice Preview icon in the right-hand Gmail™ sidebar.
- The structured data of the attachment is instantly extracted and clearly displayed.
