This product is fantastic!
It is an easier way to scan in documents that need information changed often. We have made them templates. It allows us to change already printed documents and keep the professional look.
It is an easier way to share templates with others on the team.
The ease of use and the price. The software is almost intuitive, so that almost anyone can use it without spending a lot of time. It has all the functions that get the job done.
The printing of documents requires having adobe for us. We have found that printing straight from the website, often does not print in full size. We have to save as PDF and then print. You can make it work, but it takes longer.

I think that it's a great thing. It makes fighting a case much easier.
That more people don't use it. There is nothing else that I like least about it. My vice president used it also an has no problems with it.
Being able to find what your looking for, then being able to fill form in an save it, then come back to it.

I love this program easy to use platform. As a student this has been my all in one solution. This is a one stop shop program. Seems like every need as far as documents legal forms can be found here. For myself I would recommend this to anyone who is trying to find a platform that handles all your needs. That really is to say the least I have yet to unlock all the features PDF has to offer. Thank You all the staff at PDF

So far this program is a game changer. I wish it was cheaper (a discount for teachers on a year subscription would be wonderful!) but I like what I am seeing so far ;)
