E-Rechnungs-Studio is a German e-invoicing web app that helps users create, convert, validate and view electronic invoices.
The product is built for small businesses, freelancers, agencies, accountants and service providers that need to handle individual e-invoices without installing a full accounting or ERP system.
Users can upload an existing invoice PDF and convert it into an EN 16931-compatible electronic invoice. Supported workflows include XRechnung and ZUGFeRD. The product also includes an online validator for XRechnung XML files and ZUGFeRD PDFs, plus a viewer that displays structured invoice data in a readable format.

- Readable display of structured invoice data
- Support for EN 16931, XRechnung and ZUGFeRD workflows
