What is Duet?

Duet is an invoicing and project management application with an integrated client portal

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.

Save up to $889 when you choose Duet over similar competitors

Cost isn't the most important factor when choosing tools for your business, but it's certainly not something you should ignore. If you're considering two tools, and both provide the same value, you should obviously choose the one that costs less.

Duet has the same functionality and provides the same value as all of these popular tools, at a fraction of the price. In fact, if you choose Duet over Basecamp, you'll save $889 dollars in the first year alone!
