I love that you can do everything from your phone! As an individual contractor it is essential to have all tools at my fingertips for easy accessibility when needed.
There are some things though (mainly related to billing) which could require more time/effort in order to implement them fully so not sure if worth mentioning as no big issue but just something i noticed while using this service. Make use of tech like this one because when doing work at home there's nothing better than being able to access these softwares easily without having to be physically present where they're located or connected somehow.
