The BEST Decision We Made

Laura Hardin

What do you like best?

We were previously using an all-paper hiring and on-boarding method. We switched all those documents over to Sign Now, and our whole process is so much easier and smoother. We have 7 terminals in 3 states so being all-paper was cumbersome and, frankly, silly. We've removed so much of the burden from our terminal managers so they can do what they do: manage the business.

What do you like best?

I love that I can complete signatures and documents from the phone app in addition to using my desktop. As a busy administrator, this speeds up productivity . I find the interface very easy and clear, a big win for our office. We have improved engagement with our families , and increased dramatically the amount of crucial signatures needed for our program. I have not heard any complaints that the interface is difficult or confusing, instead have heard feedback that it is easy to use. Most importantly is the ability to sign on mobile phone, this has been a game changer for us.
