I am really new at trying this out. The fax feature sounds like it would be very useful to me. I am very interested in learning about all the features offered through this service.

When going from preview back to editable view all imputed info disappeared. Not sure why that happened but I selected cancel and all info reappeared.

This has been a fun learning experience with so many options that I didn't know existed...and so easy. Thank you PDFfiller for making life easier (and thanks to Anna too, who I had an instant helpful Chat with).

Better than acrobat
Love it, my go to when acrobat pdf filler isn't working
The easy operation, we can count on it to fill any PDF. Acrobat sometimes let's us down so we started using this instead
The pricing, please lower it down so we can switch to this software forever. Also a nicer desktop App would be nice

Kara provided great tech assistance and…
Kara provided great tech assistance and she was polite, friendly, knowledgeable, and patient. The 4 stars is for Kara. The company on the other hand... not so helpful. They are great at marketing their product but provide very limited and nearly useless resources for helping their subscribers troubleshoot issues and/or educating the consumer on the tools and functions of the product. The company YouTube channel spends about 30 seconds on "how to" and the remainder of the video is promoting the product. Seriously, every single video, watch for yourself. All fluff and no substance.

AWESOME SOFTWARE
Great software, the only challenge I had was the sign in process. I have had a few accounts as I had challenges signing in and ended up making additional accounts. This could be user error but I am sure others have had this issue also.

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.

What do you like best?
Very easy to use. Super helpful. I have to complete so many forms this is an amazing addition so I dont have to hand write everything.
What do you dislike?
I would say the price, but even that isn't bad. So nothing at all.
What problems are you solving with the product? What benefits have you realized?
Like mentioned above, I often have so many forms I need to fill out. I love being able to just write and fill in the things I need. To make them look very clean and professional.

Simple e-signing and tax reporting
Due to the integrated signNow functionality, you are able to e-sign documents on the go, gather signatures from many people, track the signing progress of a document, set a signing order, and much more.
