PDF Filler ease of completing the form - that makes it look much more professional than a hand written form. I like the ease of being able to put all my information in on any form. The software easily moves you from one field to the next to populate. Everything looks much more professional than a handwritten form. I don't like the fact that I cannot save my form. I can print it but it saves as a blank form. Maybe I am doing something wrong, since I just started using it, but it did not save what I put in.

This has made me much more efficient at my job! I am having a lot of trouble with handwriting in these forms that I have to complete daily. This has saved so much pain from writing and has really increased my efficiency!

Our previous subscription was deactivated because no one seem to know the login or password for the account. It was assumed a temp employee had subscribed who is no longer employed. Difficulty accessing and filling online forms prompted us to re-subscribe. This morning's experience has been great and we plan to continue using this application.

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.

I was very impressed with this web-based PDF editor Overall my experience has pretty very positive with PDFfiller. My colleague recommended PDFfiler as I needed a quick way to sign documents while on the road. PDFfiller has all the features I need, even with the free version of the software. I think to take this software to the next level, the developer should create browser plugins to sign documents without having to upload them to the PDFfiller website.
