It was easy to fill out but I had trouble finding information on 'other' in the first section. I didn't quite understand exactly if I was to put "nonprofit organization" on the line.

i loved this. i was confused though at first about whether i could use a free trial or if i would be charged. i would recommend highlighting the free trial offer upfront to get more people to use this great product.

easy to use...but...make so forms can be shrunk so they aren't huge all the time when open, when they are huge and cannot be shrunk it can give you a headache...templates for forms ( or any often-used form) should stay at the top, to find them easy, instead of sinking down the list...you have to hit at least 5 buttons to print, and that is horrible...

It was very easy to Fill out the PDF. Then I was suprised I could also mail it, from the same website. I can upload a PDF and have it mailed, even by Certified Mail. That you can mail or fax the PDF. You can like email to fax. Which is very good. Especially since I don't have a phone anymore, let alone a fax, since I just use my Cell Phone. Technical support is terrific. They are always availble, they know everything, they are very helpful. For example, one technician let me email him my PDF, he fixed it for me, and emailed back to me.

Makes your work Easy, Professional and Reliable! Efficient and compatible with many universal docs. I look forward to completing all my documents with professional results. Monthly expenses/costs can become a concern for small business budget. It will be greatly appreciated if these costs were waived for organizations providing resources to support consumers. We work with a United Stated Private Attorney General supporting consumer claims.

A great Program Its a good program, but it takes a few minutes to get use to the actual text placement for your fill in. I did not try the signature feature. I will continue to use this program. I'll use it more often as I get use to it.

Pre Employment Applicaiton I work in HR and needed help with setting up an application to generate the same information such as name, DOB, etc on all pages to save time. Rep Kara was amazing! She was able to use my application and turn it into a pre-fillable form. Kara also provided me instructions on how to set up what I needed.
