This is a great addition to my business. Fast, efficent and saves a ton of time. I get Forms that need to be signed all the time and I just quickly upload sign/date add notes or make changes and email, fax or scan back. I could not imagine my business without it.

It's great. My kids have a lot of form for school that we have to print, sign, and then scan back into the computer. This prevents them (or me) from having to do this, great software!
