InvoicePlane is a free and open source invoicing application. The project is the official successor and owner of the codebase of FusionInvoice version 1.x, which was written by Jesse Terry. FusionInvoice was an open source software before but was transformed into a commercial product with the release of version 2.x.
Kovah, the InvoicePlane project leader, took over the codebase and restarted the project with a new name: InvoicePlane.

The Idea behind InvoicePlane

The main idea behind the InvoicePlane software is the creation of an application you host on your own server and use it for basic invoicing and client management.
The target groups are freelancers, self-employed workers and small to medium sized companies which need a reliable and easy to use invoicing system but who can't afford an expensive software.


We want to:

  • keep InvoicePlane a free and open source software.
  • provide updates on a regular base.
  • maintain a clean and hassle-free interface that is easy to learn and use.
  • offer a lot of functions and features while trying not to overload the application.
  • make configuration adn customization as easy as possible.
  • keep the requirements low so InvoicePlane can also be used within older environments.
