Kill Bill overview

What is Kill Bill?

Kill Bill includes all of the basic features a business needs to run subscription billing processes and payment processes.

The real power of Kill Bill lies in building your own business logic on top of it to create a customized billing and payments solution. You can write plugins to modify Kill Bill’s behavior and integrate with third-party vendors. Kill Bill already has many open-source plugins. Use them as examples for creating your own or modify them for your own use.

Even if you need to create your own customizations, Kill Bill is still a highly affordable solution.
