In addition to not having to worry so much about your payments, you get a nice web interface (called Kaui):

Kill bill has extensive documentation along with a suite of Youtube videos showing you how to properly use Kill Bill, so it's easy to get familiar with the software. This amount of polish in onboarding is rare with open source projects.

Along with the core functionality Kill Bill has open source plugins that you can use to get more work done.
