I was in a real pinch with only a couple of days left to send out 1099-R forms and facing having to type them on an old-fashioned typewriter, until I found PDFfiller. You saved me hours of frustration and extra work!

So far so good thou I only used it to print out claims I do like the features it has. I should be upgrading my account in the next couple of months if all goes well.

AWESOME program but too expensive AWESOME program, but the monthly cost is WAY too high. Should charge customers a more affordable price of $10/month. And stop trying to force us to pay for a whole year up front -- what if I don't need it for an entire year? Fantastic features, easy to learn, a pleasure to use. Just TOO EXPENSIVE.

Great Product! So far, my experience with this product has been great! I have only used the PDF editing features and not played with the APIs. The navigation is friendly and quick, and tools are simple and easy enough to figure out. The page loading time was a little slow in my case- editing a 10 page PDF document, but it was sufficient.

So convenient and easy! I love it. I use a lot of State and local court forms that you cannot save from their websites. With PDFiller I can fill them in and save them for future use. It seems to do everything I need it for. My favorite thing about this software is that it is so easy to fill in ANY document I may need. Maybe there could be an easier way to print right from your document, without hitting save first. (maybe you already can I just don't know how to do it)
