I’ve spent years researching and using open-source projects for my business processes. However, finding a useful application for subscription billing was a lot more difficult than I expected. So I decided to put together a list of 100% open source subscription management and billing automation tools.

I compiled this list with three basic criteria in mind. I have only listed open-source projects with commits within the past year. I have also only listed projects with public Github repositories. Lastly, I evaluated these applications based on certain critical features in a billing system, including:

Subscription billing: Being able to sell recurring (daily, weekly, monthly, yearly) subscriptions to customers.

Conclusion

Finding an automated subscription billing system is purely dependent on your needs. It is important to understand that open-source does NOT equal free. You need to host the application, install and configure it.

If you are a developer, I highly recommend using these open source applications to develop your billing system. If you are a startup needing a billing solution, book an appointment with me and I’ll be more than happy to assist you with your decision making process.

Lastly, make sure to star the open source projects and give credit to the amazing developers that help open source projects happen. Open source is the future.
