I thought I was signing up for the $6 option, but found out it was actually the $20 one. A bit deceptive. So glad I found this site though. Too bad the original PDF designers didn't create PDFs with the option of converting to Word. So, despite the deceptive billing, I am still happy I found this site, and that the website is so easy to use.

I subscribed for one purpose - to be able to print numerous amounts of Genealogy Forms. This is fulfilling my needs with minimum issues. It is a great product.

No, I think its a good program. Just a few things I need to learn how to use. Although, it's a bit costly, I would like to keep using, but it may be expensive for my business.

PDFFILLER HAS CHANGED MY PRACTICE - FOR THE BETTER I use this software everyday and have found it a necessity in my practice. Prior to having pdffiller, we still had to type into forms using a TYPEWRITER. No joke. With my legal practice there are numerous forms that we have to fill out. Not only does pdffiller have the usual ability to enter Text into a form, but the feature we rely on the most is the ability to DELETE and RE-TYPE into the document. This has improved the time it takes to draft and amend documents that were not originally created by our office. Sometimes it is difficult to save under a different name and I often accidentally save over a prior document.
