To start with I struggled a little bit and thought it wasn't working. However, five minutes into it I was already achieving what I wanted from the editing futures of this program. Many thanks.

Very helpful tool for 1099. How do you auto populate though. I find it tedious to manually type the same info over and over. Still WAY better than the alternative though. Thanks.

Getting to put 3 people on the account has been great. All of the features are exactly what I needed, and the editor is easy to use. I was a little wary if it would be worth the money, but I'm very happy with my purchase.

What do you dislike?
Sometimes difficult to switch back to doc
What problems are you solving with the product? What benefits have you realized?
I've been able to recreate documents into templates and this way it is easy to fill out when they are used repeatedly. I also like the signature part makes signing docs very handy. I haven't used, but am excited about the notary part that was added.

It seems extremely hard to download a form fillable PDF without paying for a premium PDF reader. I don't have a problem paying money, it's just silly that I have to in 2019. There are so many of them...

The overall experience was good, the only thing I would say is to increase the number of signatures from 10 to 100 in the case of signatures for the same document.

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.

user friendly and practical, what would really differentiate would be the possibility to use the app when offline and automatic synchronization once online.
