What do you like best?
I like being able to streamline our company process with our patient's paperwork.
What do you dislike?
I use the Sign Now that the availability comes with the Platinum pkg. I found that I have to keep resubmitting every document I upload...I have to refresh the page. Every document I send out I have to refresh the page again. I know to clean my cookies and Cache and I still have to refresh.
What problems are you solving with the product? What benefits have you realized?
I love the fact that the clients can sign their documents as we wait instead of looking for an email or having to print it out sign it and then get it back to us.

Fill in the Blank
Love what this has done for making my job so much easier at a very reasonable rate.
For my business this was and is the best tool I have for putting together insurance reports. Build or scan in a template and fill in the blanks when you need to send a report out. BAHM! DONE!
Probably something I have not spent enough time to figure out yet but as of now each time I fill in a blank template it auto saves it so my original always has to be cleared before new entry.

Excellent cloud based software that I am able to use on any computer!
Easily able to share between documents that are signed between multiple people.
I love that I am able to use the software on any computer or phone with ease along with signing PDF documents!
I would like if I could create boxes easier that were adjustable fields rather than just having a single section.

Very useful tool
Useful app for managing all your pdf tasks. I always use this app to sign. Very recommended.
It doesn't have many free features, you have to pay for the good ones.

I thought it was a bit difficult to get a form completed. All I wanted was a statement that I paid my neighbor for a dent in his car. I had to hunt for a form that would allow me to enter that statement.

What do you like best?
The best thing is simply how it works. So many forms that need to be filled out and they are sent in formats that don't allow that. pdfFiller fixes that problem.
What do you dislike?
I haven't really found anything that I dislike. It's a great software.
What problems are you solving with the product? What benefits have you realized?
I do private consulting for government contractors and we have to finalize a LOT of Non-Disclosure Agreements. pdfFiller makes that a snap. Also we have many forms that have to be executed and it would be so difficult without this program.

It works really good although saving process for the PC is a bit bad because it doesn't save documents directly.
