Like the program, although it does seem complicated. However, I keep receiving error messages when I send docs to be signed, and when I send it in I receive a message saying it is on our end. I would like to use the program for many things, especially getting signatures, although it seems that isn't included now and is additional cost, so I may go to authentisign

What do you like best?
The ability to edit practically any document, within reason. As a Finance professional, it's much easier to add a JPEG of a signature to hundred of checks rather than signing them by hand. My carpal-tunnel free wrists thank you!

I don't have any negative comments; everything that the program promises, it delivers.

Expensive for irregular user but overall excellent! Expensive if you are an occasional user, and I wish the "fill in the blanks" were a little more automatic with alignment. But overall excellent!
