I am using this service as an ex-pat in Ecuador to communicate with government services in the U.S. Not certain yet if offices like Social Security will accept forms mailed from an online-filler service, so am withholding the 5th star until I know they'll actually accept my forms.

etter than expected!
I us I nearly every day. It saves time and hassle,and it makes PDFS easy to customize. I love it!
I go this software to fill out forms, but it does SO much more than that! I can take educational PDFS, and change items to apply to my young students. Even the younger teachers in my group will send me a PDF, and ask me to "Do your magic" on it. My "magic" is PDF filler!
Wow....there isn't much I would change. It really works so very well. I might want to see a few more fonts available.
manage all documents with PDFFiller
easy to convert files create file and handle all types of files .
few extensions are not available and some files create problems after converting .

I signed up to help with a real estate…
I signed up to help with a real estate contract. I was able to complete the form and email the document. It took me a little while to figure it all out but once I did it went smoothly.

Fumbling along with Adobe Acrobat or hand-writing forms was time-consuming, sloppy, and completely inefficient—especially if changes or updates were needed. We are going to continue to use pdfFiller and find additional uses for the product as our business grows.

pdfFiller saves us $100 or more each workday when you factor in employee time and supplies. The figure is probably higher than that, since the waiting time for patients not yet seen is also diminished, which keeps the patient from being frustrated and just leaving before their visit.

I needed a platform that could merge documents together, edit them, sign them, then email or fax them. Ideally, all in one. I was introduced to pdfFiller last year. So I just went and got an account for myself, and have been using pdfFiller ever since.
