I like that I can find most of the forms I need bit it is very difficult, at least for me to align some of my typing to the actual corresponding lines. (eg): pleading paper. Im sure there is a way but i haven't learned the whole program yet

I like erasure feature in biz version. I find your index very hard to use. Where (what tab; how do I get there) is you general index of library contents and categories?

Ease of use is great because I am a one-person office, and don't have access to a lot of office machines, so this works good. I just have to figure out how to get it to scan.

HOW DO I EDIT A FORM I HAVE ALREADY DOWNLOADED I love the fact that I found it easy to edit my documents. I could edit and download as many times as possible. Found a lot of useful information on the filler too.

Amazing software Amazing software, Unreal flexibility for the price. Only thing I would change is possibly the phone numbers as we are not all in US. All in all, saves hours a week.

So far so good So far so good. I like the friendly interface and the different options of sending processed files. I would like to request developers to incoporate "rotating page" for some documents that may be uploaded upside down
