Who the bundle is for

For businesses that check and pay their incoming e-invoices themselves, and for everyone who wants a complete workplace for incoming invoices without installing anything.

Validation with the Mustang validator runs through the Validator Bridge on your computer. You install the validator itself there; the bridge makes it reachable for the one-file app.


How the bundle reaches you

In the shop you get a ZIP with the one-file app of the viewer and the add-on files of the extensions. You unpack it into a folder and open the HTML file with a double click. The add-on files sit next to it, and the viewer loads them at start.

You can pass the 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 tools individually as WordPress plugins.

This bundle is new; the demo follows shortly.
