Although I initially had thought this was free, the overall experience is a positive one. The insertion process could be initially a little more self-setting / precise but overall good to use for my purposes

A little overwhelming at first. Trying to send to a client to fill out a form but it seems a little difficult. A webinar would be nice. I am going through the FAQ with some success.

The Popups that direct you to what to fill in are annoying. Would like to be able to turn off. Other than that Love PDF Filler Way better than my current management system's accords!

THERE IS A REAL PROBLEM WHEN TRYING IN FORMS THAT YOU IMPORT YOURSELF. IF YOU TRY TO MAKE A CHANGE FROM ONE SECTION TO NEXT IT AUTO FILLS ON ITS OWN AND I HAVE NOT FOUND A SOLUTIONS FOR IT

The "Draw" tool needs to have an option to match the color on the picture or PDF page so when you're drawing you don't mess up your picture so bad!

PDF filler- Great for client invoices and forms Great time and paper saver. Allows me to send forms write through email and receive them back. An easy to use option for clients to enable transfer of information without needing to print and scan documents. Not everyone is familiar with it. Sometimes it is difficult to select the text box to edit. Some people can't do the signiture option.

I signed up for their services during a free trial, but ended up not needing them. When I realized I had been charged for their services, I immediately emailed them and they processed the refund right then. I offered to pay for the few days that I actually had since it was really my fault, but they refunded the full amount.

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.

At work, I use ABBY and it is very effective. I didn't think to get that before I chose this. I was searching quickly, but am ok with it. I would to redact in groups by typing the first few characters.
