Good question.
Outside of Vincent, here is our full list of stuff we are doing with it and what we plan on doing.
Client data, day to day tickets, marketing reports, inputting to QB for financials, managing prepay clients, Google calendar synching for scheduling remote and home/business visits, invoicing, view tech tickets for just about anything,
Easy to use, configure and understand
What we are doing soon:
Monthly pay clients
apps for smartphones for on the road techs/special account techs
Other than that, I am sure that I have more coming up. I have been slow to integrate it 100%, kinda nervous of getting off my old Excel spreadsheet and my techs are sick to death of it. We are in a 2 week ween off period and then we are 100% into it.
