I have been using it for about 3 months now, going from pen and paper and manually typing up invoices it's a huge time saver when it comes to collecting payments and keeping records.
Scheduling is extremely easy using the check app. The app also makes tracking expenses and earrings very simple.
I feel like it makes my job a lot easier. Keeping track of who owes what and how and what they paid. The route tool makes it where a lot of the aspects of the job are almost on autopilot.
