I wanted to create 2 additional 1099s but was unable to find that option so closed and requested it be sent to IRS. Now I know I should have selected "template" but have not been able to get that to work. Made another, and no option to send to IRS

PDFfiller is a good value application for PDF file editing, filling and file management. My limited use of the application so far leaves a lot of its functionality to be discovered. However, it is very user friendly and simple to work with.

THE BEST support team I have ever had, EVER!!!!!!! Best support team I have ever had. I used the dreaded "CHAT" where I usually end up banging my head against the wall. Today I chatted with Sam and I am dumbfounded how great things went! I can honestly say I have NEVER had the satisfaction that I got today! I can't even think of a chat before where I felt human afterwards. Today, I am gobsmacked how well everything went!Sam took care of what I was there for and did it with professionalism like I have NEVER experienced in a chat with a business!I can not say enough about this company! If Sam is an example of the company, which he is, then this is a 10 star company on a 4 star scale!

Easy to execute the changes needed… Easy to execute the changes needed without much instruction. Saving in the pdf filler on One Drive was slow (undoubtedly Microsoft's problem).
