What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Since this is my first time and I have never used one of these before, I am still learning. But so far am happy with it. I just wish it was easier to actually contact a human being to ask questions when I am not sure about something and so have to search and keep trying to find what I want.

It was the only source I could find to obtain 2014 Form 990 forms. The IRS site shows 2014 forms tabs but they are for 2015 which is the wrong form. I could not find the supplemental forms I needed by searching the website so I gave up and contacted customer support on your chat line. The rep was very polite and sought out all the supplemental forms I needed to finish the job. That's a real plus but I should have been able to find the forms on the website.

A reliable and quick to use PDF signing and editing platform
Quick and easy signing for PDF forms, especially on mobile devices.
PDFfiller is web-based, so it's easy for me to access on my phone if I need to quickly sign or edit a PDF file.
Additional features in the paid subscription model (more editing options), would convince me to sign-up for the paid versions of the software.

Once I figured out how to use the eraser feature, this software was immensely helpful. Occasionally, it did not print the lines on Schedules K-1, but eventually it did. I have now successfully downloaded a file from the IRS and merged it into the file I was working on with pdf Filler. I really like this software.

Top notch tool for all your document editing needs pdf, word and much more
It has been great using PDF filller, its awesome to be able to edit and sign documents from my personal computer and use them for school and work. Everything is pretty seamless and self explanatory, and I have yet to experience any real issues.

What do you like best?
The ability to send a link via email or text to allow a client to sign a document makes things a breeze! I also like having an "encrypted" folder that's password protected for my access only.
What do you dislike?
Nothing really that I currently dislike about the online software.
Recommendations to others considering the product:
If you're looking for a very affordable alternative to DocuSign or any other "Send to Sign" type of software, this one takes the cake!
What problems are you solving with the product? What benefits have you realized?
I have access to Law documents vs. having to google something for a layout where I can save it & populate the information I need from my data.
