It's easy to use, I do like it; but it is a little expensive, $80/year is a lot. I use it maybe once or twice per month. I think you would have more customers if it was less expensive.

I have enjoyed the security features and collaborative document sharing feature with electronic signature, which is crucial to reports in the medical field that are sent between departments safely with required documentation.

It had some really great features but not as easy to maneuver through as I thought it might be. Was expensive with no other option for a company that does not need it that much.

This program was easy to work with; however, I misunderstood that the forms I was trying to use were copyrighted and had to be completed in another manner. Customer service was very prompt in responding to questions; and, for the right forms, this would be an awesome service.
