VERY CONVENIENT!!!! I had something urgent to fill out and I couldn't fill out the form and this helped me to fill out and E sign as well as send it by email. Thankful I found the site. Needs to be advertised more. I could have used this years ago.

I found it to be very useful but expensive. I wish I would've had the option of paying monthly instead of a one time upfront transaction with no warning.

Definitely an aid needed in my industry for State regulatory data gathering forms. Tedious and every facility utilized the 35 pg form differently with no consistency. The tool is also very physician specific though as a Nurse Practitioner a good degree of crativity is required to enter the desired information that has no technical heading/home within the document. Adding pages and making duplicates is key as it often required, especially with added clinical experience and with work history. The ssimple 35 pages easily grows to over 60 at times.

in a nutshell: sooooooooooo much better than adobe acrobat. i'm a new user, but this was just infinitely less frustrating (and i'm hoping less expensive) that dealing with adobe.

What do you like best?
I like that we can search the internet for fillable forms. I also like that we can email and fax right from pdffiller
What do you dislike?
The only issue I have had is when using the iPad or iPhone version. The dates become messed up for some reason. Very simple to fix once I’m back in a computer though.
What problems are you solving with the product? What benefits have you realized?
This allows me to send insurance documents without having to go through multiple websites.
