Much easier/more intuitive than past editing systems I've used! Don't love that I found out only after editing an intensive document that I had to pay though :/
Lena Beth S
As a new small business operator, this software has helped me with so many tasks without having to leave work. The only draw back is that many times, recipients can't open sent pdf files and another route has to be taken.

What do you like best?
PDFfiller has helped me streamline my forms and remove paper forms for my workplace. I am now able to have all my paper forms eliminated replaced by online forms. Saves alot of paper and trees!
What do you dislike?
The think I dislike is when a user completes a form online and I am notified I have to click the email link, save the form before I am able to view in my dashboard. Be nice to just have the form in my dash ready to go without the other intermediate steps.
What problems are you solving with the product? What benefits have you realized?
Definitely help streamline work and remove paper forms. Also saves me time with clients filling out new intake forms before I even see them.

****** from PdfFiller is Excellent!I needed to cancel my service for the time being for financial reasons and they handled it kindly and seamlessly with no hassle. Should I need this type of service again, I will definitely be back. Would recommend PdfFIller to others. The service itself is intuitive and helped me easily provide my on boarding information for my new job.

I initially thought that PDFfiller was a free tool. Even though they asked me for my credit card information with a free 30 Day trial I forgot about the same. When I got an email a month later stating I had been charged for the whole year I logged in and chatted with Customer Service. They were so kind as to immediately understand, cancel my subscription, and agree to issue me a refund. At the time of writing this, I am still awaiting my refund as I just requested the cancellation today - but I must say that this gesture was amazing by PDFfiller and this review is the very least I can do. Thank you for brightening up 2020 a bit! Amazing business ethic and professional courtesy.
