I needed to type on an older document and this program seemed like a good choice. Also, since I can pay month to month I can stop when I am finished with the paperwork and that was a nice option.

Makes pdf edition easier In our office we need to fill a lot of IRS, FDOR and Court forms. This software allows us to fill them and save them a feature most of the governmental entities don't allow us. It also allows us to erase and edit all pdfs which makes our lives easier. It also allows you to load a document from every possible location, even has its own data of forms. What I don't like about this software is that in order to go to the next page you can't roll down you have to switch pages and sometimes I end up missing a page of the document.
