What do you like best?

My favorite part of this software is how easy it is to use. I can input where I need signatures, initials, dates or text on all of the documentation so easily, and I have not had one client ask how to use it or sign it, and my clients age from 23-65. It is so user friendly and makes my business run more efficiently than ever.
