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.

EASY TO USE, TRULY ALLOWS ONE TO EDIT PDFS. I WOULD LOVE TO SEE MORE FONTS AND THE ABILITY TO SET THE FONT SIZE MANUALLY, AND SMALLER THAN SIZE 8. OTHER THAN THAT, GREAT, USEFUL APP.

PDFFILLER PDFFILLER, I have tried many and many have failed, typically to overstate and underdeliver, however. PDFFILLER, is the nerd in the room understated but delivers at every turn. There have been times though that I was sure they misssed something, that is untill I call support and talk about delivery. A product is only as good as the support team behind it. Hours spent trying to figure out this glitch, testing this and testing that, and the support agent just as friendly and helpful at hour three as at hour one, come to find out, it was my network, my VPN and firewall wasn't letting me upload documents, others were good and worked fine. except from my phone. Even then the agent was doing even more testing and providing his findings via screen recordings over email. I was amazed and it wasn't the first time. incredibly knowledgeable and professional. I am not an easy person to please as most software isn't completly vetted before release but PDFFILLER has done their work and worth every penny.

I made a mistake and accidentally… I made a mistake and accidentally signed up for this service. When I got the bill for $96, I was shocked. I thought it was going to be such a hassle and was so pleasantly surprised. I got a full refund within an hour of writing to them with a very nice note.

PDFfiller works great, but do not understand why a person is forced to use this program to fill out forms for the DMV and DNR. I should beable to download a form, fill out and mail.

What do you like best? I often need to fill out forms for work. With Pdffiller it is simple to upload forms, fill out, save and download to email. I also use it to merge PDFs as well. It saves all of your work and keeps the documents in my account for future reference or an easy change/update. What do you dislike? There are a lot of features and sometimes it is hard to find exactly what I need. A simple "How do I .... in pdffiller on google usually takes care of it quickly. What problems are you solving with the product? What benefits have you realized? Before Pdffiller I would print the document, fill out by hand, scan, then email. Now my documents look more professional without and are less of a hassle.
