Duet

Beautiful self hosted invoicing and project management with an integrated client portal.

Duet is self hosted so your data is always private, and it's completely brandable so that it matches your business. Best of all, its low one time fee means you will save hundreds over similar software

More control and better privacy - Duet is hosted on your own server, on your own domain, which means you're in complete control. No one has access to any of your data unless you explicitly give it to them. You can control the way it looks and even the url it's accessed from.

Customize and brand Duet to match your business and it's processes - Business class software is not one size fits all. Duet lets you decide which modules and processes you need and gets the rest out of the way. Support your brand by customizing the look. Upload your logo, change the theme, use the built-in css editor, or modify the source code directly.
