InvoicePlane

InvoicePlane is a free and open-source invoicing application designed for freelancers, self-employed workers, and small to medium-sized companies. Developed by Kovah, InvoicePlane is the official successor and owner of the codebase of FusionInvoice version 1.x.

With the main goal of providing a reliable and easy-to-use invoicing system, InvoicePlane allows you to host the application on your own server. It offers a clean and hassle-free interface that is easy to learn and use. Despite being a free software, InvoicePlane offers a range of functions and features without overwhelming the application.

The project aims to keep InvoicePlane as a free and open-source software, regularly providing updates and maintaining a low requirement to ensure compatibility with older environments. With a history that dates back to May 2014, InvoicePlane has grown to become a popular choice for businesses worldwide, with over 100,000 downloads across 196 countries.

Support for themes, up to 25 different payment providers, and many other interesting features make InvoicePlane a comprehensive solution for all your invoicing and client management needs.
