I was allowed a 2 week free trial following an online chat about the product. I was so impressed with the features that I purchased an annual subscription! Very user friendly! Great customer service via chat.

making insurance certificates for our own insureds so they don't have to wait for us. I can see who they make certificates for and add them to their account

My life is so much easier with PDF… My life is so much easier with PDF filler. I can instantly complete any paperwork I have. I was able to figure out how to use it without reading any instructions at all. Even better, I am saving cost and waste of printer and paper.

I've been a customer of ********************** for almost 2 years now. The program has completely upped my game from writing business letters, filling out pdfs, faxing important documents - there is no limit to what you can do with a program like PDFFiller. But, what really pulled me in, other than the superb professional look and quality that PDFFiller gives my correspondence, was the help I received when I needed it. For example, I needed help with merging two documents that I needed to fax. I received help via the Chat Box within seconds of asking for assistance. It's like having your own IT team 24 hours a day! I also just found out that outbound faxes are included in the price and, if you want your own inbound fax number, $20.00 a month gets you your own fax number! The list goes on and on. I can't say enough about PDFFiller! Complete professionalism, confidentiality, and customer oriented. Try **********************! You will not be disappointed!
