I had to refile my last 4 years 1040 and all tax docs. After going through the IRS web docs but unable to edit them I found all the docs on the PDFfiller website. After a little work with the editors I was able to process professional docs. I bought a year sub and look to see if I can use this app for other business uses.

Initially, it was a bit confusing. However, after using the program a few times, I am delighted. I very much like the fact that I can take a printed form, scan it, and then fill it in and print it. The result is very professional looking. Still not sure how to change fonts.
David W. Hess, D
Easy and intuitive to use - could fill out forms right away with little effort. Signature capture using the laptop camera did not work - the signature ink lines not clear after cleaning up the image. I scanned my signature at 300dpi using a scanner, and saved that image. I tried this, liked it, and bought 1 year subscription.

Just started. Good so far. I wish it connected with our online storage so that completed forms could be automatically added to our storage instead of having to download them.

It has been pretty good , but right now i'm having a problem because, it wants to verify and send a passcode to my e-mail, but i can not enter it because it is not showing up in my e-mail

I have been trying to cancel my… I have been trying to cancel my subscription for months. One of the problems is that I can't find the account. I have tried all of the email addresses that I use and can not find it. I have sent emails and wrote tickets trying to get some help but have recieved absolutely no response. I am paying $50 a month for a service I am unable to use or cancel. I was able to finally talk to someone who helped me find the email the account was under, canceled it for me and refunded the charges. The whole thing was quick and painless and I got the best possible outcome and that gives the 5 stars in my book. Thank you pdffiller for taking the time to hear my problem and helping finally find a resolution.

What do you like best? The tools are easy to find in PDF filler. What do you dislike? It is sometimes difficult to execute certain tasks when the pre-highlighted boxes appear. What problems are you solving with the product? What benefits have you realized? I have learned how to use it better, which has negated some of the issues. It is a helpful tool for a job that requires me to fill out many PDF documents.
