It think it can be very useful once I get the hang of it. Disappointed that for a yearly subscription of $72.00 you don't get access to the erase feature. This feature is even free online. Do consider and include it.

They have very quick and responsive…
They have very quick and responsive customer service. I was greatly relieved to have my issue resolved in a very timely manner.

I use this software daily to mainly merge other documents into one PDF. It's very user friendly.
time management and expedition of documents requiring signatures!
Merge feature and being able to delete pages that I don't need. I like that I can save my agency's details on the different forms I use; rather than retyping each time.
It has locked up a couple of times but once I get out and go back in it's fine. It hasn't happened in the last year so they may have done some updates to the software.

It got the immediate job done but there were a few hiccups. I don't particularly like their way text is displayed in the larger fill-in fields. The form I was filling out was very complicated and required numerous references to a "Remarks" section at the end of the form because there was insufficient space with the numbered questions to put complete answers without overwriting onto the next numbered question. Consequently, the Remarks section was filled necessitating a separate attachment to contain all the remarks. In the remarks section, I cross-referenced to the numbered question for clarity, e.g. "Question 12(b)..." When I viewed the form on the screen the formatting looked fine but when it printed, the "Q" in the word Question was on one line and everything else "question 12(b) was on the next line. I would like to know how to avoid that issue in the future.
