What do you like best? It is very helpful to be able to fill pdf's in. It also saves paper and time. I hate having to print a form out, fill it in by hand and then scan it into the computer just to turn around and email it. With pdfFiller I can do the work on my computer, it looks professional and then I simply save it and email it. I also like the fax option. What do you dislike? Sometimes I have a little trouble getting everything just where I want it. But the more I use it the easier it becomes. I feel that I will like it even more the more I use it. What problems are you solving with the product? What benefits have you realized? I am solving the wasted paper and time. I am able to keep everything electronically. Forms look more professional. I do not have to pay a separate service for a fax line which I only use a few times a year, I fax straight from pdfFiller.
