It took a while to begin to understand how this works. I would definitely like to attend a webinar to learn more about it. After I fill in all these forms I send you, how do I save them to my computer? Thanks, Joyce Wicks

The ease and operation was fantastic. I get confused very easily with all the new technology. With PDFFILLER I was able start at file I found in the browser and fax it, import a file and email it without any trouble. I will be using this a lot.

Gives our company the posibility to aply signatures on docs. And doing corrections on different PDF with mistakes. In our Buisiness its very common to have changes in final documents as puchase orders. And PDFfiller is a great tool to correct mistakes that we have to face everyday.

Great online chat support! Support when I've needed it has been great which I can rarely say about most companies these days. While the program tends to be a little cumbersome it works for what I need it to. When I have issues the online chat support has been great an very little wait to get to someone. John resolved my issue over the weekend and Kara fixed the one I had this morning - I really appreciate both their help!

I would recommend this site I have found the site easy to use and have not any problems with it. If I hit a snag with the functions I contact the team and they always sort it out for me. It certainly has made my work more efficient now that I am working from home.
