Needed some Quick 1099's - PDF Filler Came to the Rescue Good product for what it is designed for. Downloaded this in a pinch when I need to get a vendor a 1099 last minute. Couldn't find anything that would allow me to do this on the IRS website and PDF Filler allowed to complete one in a matter of minutes. Definite a lifesaver and helped me save a relationship with a vendor. Automatic renewal snuck up on me. I didn't mind paying for it the first year, but this year I didn't need it.
