What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Easy to use, a little misleading on the web site "try for free" and then it wants to charge me to save / print, but live chat was quick and the chat agent (Anne) was awesome and provided me a 7 day free trial so I can see if this will be worth the subscription. Hats off to the chat agent, awesome customer service, GIVE her a RAISE! LOL

I was allowed a 2 week free trial following an online chat about the product. I was so impressed with the features that I purchased an annual subscription! Very user friendly! Great customer service via chat.

The first time I downloaded the software, I mistakenly selected the one for use with Microsoft and all features did not work on my Chromebook. After going back I found the correct program for use with Chrome. The only problem I still have is creating my signature which I have described below under features to add.

What do you like best?
I like that I can fill in forms for all of my taxes, and they are saved permanently for future reference.
What do you dislike?
It is difficult to find a form that I need. I have to do a general google search, then click on the link, and fill in the form, then log into my pdf filler account. Wish it were easier to find specific forms.
Recommendations to others considering the product:
It's an excellent product for filling in forms, and creating documents.
What problems are you solving with the product? What benefits have you realized?
taxes. It has been helpful for me for the quarter and yearly tax forms I need to fill out (941, 940, W2's, W3's and 1099's).
