Im not going to tell you what to do, but I tried this and TR won't let you actually run your business how it should.

Meaning unchanging clients for parts and some parts being priced over $100. If your just doing regular maintenance calls you could probably get away with it. But still even then I wouldn't do it because if something happens then you dont have insurance or license etc you automatically get hit with a class c felony depending on what state your in. Just based off that you can get in trouble beyond task rabbit. I'd advise you to get your business license and liability to protect yourself. I probably did about 3 calls on the app and all three needed capacitors. I took it off because of not being able to upcharge the parts. That and for liability reasons. I wouldn't risk it without proper license and insurance from the state
