Best program Ever! This software has changed our business. We are in a very form intensive business and not all forms come in electronically. PDFfiller allows us to convert them and manipulate them to our liking. Saves us tons of time and effort. Nothing I don't like. This software has allowed us greater efficiency, allowing us to focus our time on other things.

Kara was VERY helpful Kara was very helpful, especially in suggesting we do a Zoom screen share, which made some problems I was having with navigation and document publishing much clearer. She should get a raise.

Excellent customer service. Keep it up. Excellent, excellent customer service! I contacted the company because I was charged a subscription fee which I wasn't aware that I had not yet cancelled. The customer service representative called Anna, I believe, immediately informed me that the subscription would be cancelled and an email to that effect was sent to me. I was also informed that my money would be refunded shortly....and indeed, it was returned to my card in 48 hours. Although, I don't have need for their services at this time, I would definitely use them at a later date, should the need arise.
