Love it I love it and have recommended it to friends and collegues. Love the ability to change forms around and manipulate the forms to move entire sections around and still keep things neat and professional looking. The dashboard is messy and not as well organized as it could be.

Easy to use Easy to use. I wish I came across this solution first because with it I was able to do in 10 minutes what I couldn't do in hours with the other editors I tried, not counting all the time trying to find them.

Making signing easy It was a great team friendly program that made things get done a lot faster and more efficiently even in large with large numbers working on the same thing. Makes getting multiple groups of people working on one thing done faster with not all having to come to the same place. Sometimes it was difficult trying to download the papers once the words were added.

What do you like best? I use it everyday for certificates of insurance, the program is very user friendly What do you dislike? I have tried to save the link on my computer but it never saves. I always have to google acord PDF filler. What problems are you solving with the product? What benefits have you realized? It saves all my COI so I just need to change the date and certificate holder.

Not very user friendly Not very user friendly. The "sign-up" commitment is not good... Inevitably some people will forget to cancel and then will be hit with a high annual charge...
