One-file app · Demo

eInvoice Viewer Bundle Inbound as a one-file app.

A one-file app is a single HTML file. You open it in your browser, without installation, without a server and without an account. The invoice you drop into it is read in your browser and is not uploaded.

This demo is the website edition. It checks your own invoices within a daily limit; the sample files included always work.

  • You can pass a one-file app on by e-mail, put it on a USB stick or copy it to a network drive.
  • If you need roles, daily limits and storage, use the WordPress plugins.
