thanks for your attention.
I asked some questions in gitter room please answer them in gitter or here.

Hi, I want to use service but for my project, I need some of the features but not all of them. I going to remove the admin dashboard and use the api instead (is it possible?) then I’m going to remove strip payment and add another one.
The gist: I’m going to use the core of the ServiceBot in the part of a back-end api gate-way for billing solution.
What're the problems in this situation I have?
How can I implement it?
What're your hints?
Which branch should I start developing on it after I forked it?
Where should I start reading the project?
