So far works as advertised! professional version should include like a few business features to use like 10 times a week etc. That way I would give it 5 stars!

It took just seconds to send my agreement for signature. The customer experience inspires confidence in the security of the transaction and gives a good impression of my company. It is far better than the old - email it, print it, sign it, scan it, email it, "did you get it?"- approach.

PDF Filler makes my job EASIER! PDF Filler makes my work so much easier. I am a teacher and I need to change PDF files all the time to meet my students needs. So, before I would print out the original and have to white out what I needed gone and make a copy. Now, I can just upload to PDF Filler, change what I need changed, save a copy of the changed PDF and have it ready to go. I love PDF Filler. Thanks for making my job easier!

Works well Works well. Just wish there was a way to sign without the added date and time and logo. No one cares about the logo, they just want a signature that appears real. I still have to print, sign and scan, because of that one issue. Kind of makes it worthless to be able to fill out on line.
