Free and open-source billing and client management solution.
Completely open-sourced
FOSSBilling is completely open-sourced and licensed under the Apache 2.0 license. We don't encode any of our software, so you can be sure that you are in control of what runs on your infrastructure.
Extensible
FOSSBilling is designed to be extensible. You can easily add your own custom modules to extend the functionality of FOSSBilling. You can also integrate FOSSBilling with your favourite server management software and payment gateways.
Backed by the community
The project is entirely funded by the community. You can support the project by becoming a sponsor. Our expenses are listed on our Open Collective page too.
