Protobill is designed to be a clean, secure, flexible, and extensible open source billing system. We want you to contribute, find bugs, and build your own incredible creations with Protobill.

All issues and pull requests should be filed on the connor4312/protobill repository.

Protobill is open-sourced software licensed under the Mozilla Public License. This means that you can use Protobill, and mix it with your own software and services. However, and modifications made to Protobill's own functionality must be open source - maybe the easiest way would be to put in a pull request and make your improvements part of Protobill itself, eh?
