Solo-operators love Check because it helps them get organized and feel in control. No more dropping the ball and losing money from being disorganized.
I really enjoy the pay by invoice feature. My clients love the secure pay option. It saves me time so I don't have to stand at a doorstep while the customer finds cash. I can send them the invoice and head out to the next job.
Ease-of-use, ability to do everything off your phone, and the 24/7 access to the entire client base at the tip of your fingers will help you prevent scheduling conflicts, improve revenue.
It's very easy to use and the app works perfectly. Reasonably priced service as well.
