So far so good. I don't know why when I add pictures it doesn't come through in the email. Plus, I don't know how to edit a form once I've completed it.

Good site/product. The only thing that bothers me is that is seems like when you email from the application (rather than save to your computer and forward) it seemingly wants the recipient to "buy" PDFfiller in order to print or use the pdf. I might have this wrong based on a hurried initial exchange.

Filling out form was fine. I felt like I should have been told there was a cost associated with use before I filled out form, not when I finished. At that point I didn't feel like handwriting everything, so I paid for subscription. I can't justify spending $72.00 a year for something I will seldom use. Wish I would have known up front this was not free.

Mostly I am thrilled with this service I didn't know I needed... until this week... and I needed it twice!! The form MC 030 was glitchy when it came to cut and pasting and editing the comments section. My only complaint.

PDF filler is easy to use and let's me change documents as needed.Unfortunately, some of the features available on the computer are not available on the Ipad. Creating fill in lines for example.

PDF Filler has been a great tool for our business for a professional look with a great price. Professional Look for a cheap price. The software makes filling out government documents / applications and other PDF documents easy and efficient. PDF Filler provides and saves time when filling out applications / tax papers / and other business files. It creates a professional look and is quite easy to use. With common files also at hand it makes filling these out quick and easy. The mail tool was even used when we completed our taxes. PDF Filler printed the paper out and mailed it themselves without us ever having to go to the post office. There isn't too much. If I could say anything sometimes the website moves a little bit slower than some. However this seems to have been improving lately.

Great program Great program. Let's you edit PDF, sign documents, send documents to clients or other persons to sign electronically. Also gives access (at least my package) to some limited legal forms which is helpful. Would highly recommend.
