I like the fact I can do this online. But, being new, it's complicated finding my way around. I cannot figure out why the font changes size when completing column J - both lines.

PDF filler has been a life saver! So many times I have been required to fill out documents that most would typically print out, fill by hand, scan, and email back. PDF filler has allowed me to save time by being able to fill out the forms digitally, tremendously increasing my productivity and turn around time. All documents are neat and professional-looking, including my digital signature! Initially I was unsure about whether or not it was worth spending the money on PDF filler b/c I wasn't sure how often I would be using it, but now I would definitely say it's worth it! An absolute necessity for any business to have to get things filled out quickly and neatly!

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.

It works like a charm
Copy, paste and cut text on PDFs in the document editor.

At first I thought they were scammers, but I took the risk and paid for what they asked for. Now I use almost everything they offer.
I like that I do not need to download and upload the document back.
I would like to print the document immediately after editing. Now I need to save it first and then I can print the document

It's too early to comment.
It's too early to comment about my experience. I started using this software today. Whatever I work I did today . with the software was a satisfactory. I need to try many other features and train myself using this software, before I can comment about my overall satisfaction.

Support is good but last release is bad
I am really fond of their support team. They are very friendly and provide all help the can. But that's not enough for good product. Support can't fix bugs or make it good for tablets. Try harder.
