The pdf filler has been excellent to use to date. I haven't explored the other options available, such as sign and send, although, I will definitely look into a full options account.

Was a little cumbersome at first, but was able to figure out on own which says a lot about a computer program minus an instruction booklet. Yeah, I'm a little on the geek side.

I've just started the trial service but so far I'm finding the software very user friendly. I've uploaded an application used by our non-profit and marked all the fields needing completion. It was very easy to do. Testing has gone well. Looking forward to using this for our membership drive.

Pleasant PDFiller!
I use PDFfiller almost daily. I work in Accounts Receivable and customers frequently like to have additional information added to their invoice. This is something our accounting program cannot do.
Very user friendly. Very appealing to look at.
I don't have any cons. I haven't found anything that I don't like about it.

The learning curve is not too steep. I'd feel more confident with it, if there was a way to save the document other than clicking DONE which closes it....it's better than the government forms I've hassled with!
