I had a little issue trying to find out how to print the form. Also, the little movable box that kept showing me where to check got in the way of reading the document. I X'ed it out most of the time so I could read the instructions.

This software is much better than any other our company has tried. We became frustrated with our previous form filling software and therefore decided to try PDFfiller. So far, it is working great!

An Alternative To Adobe Run a small business without additional Adobe and DocuSign subscriptions.... It is a great value and it surprises me with new features on a quarterly basis. When I need new functionality I search for it and am no longer surprised when it is there! I wish it would break down .PDF text into MS Word documents.

Very quick, efficient and courteous customer service. My elderly mother subscribed to this service and couldn't remember why. I explained the situation via emails with Customer Support and they refunded the annual subscription fee after I verified a few details. I really appreciated their understanding and quick response. Now...I have to go unplug my mom's computer. :-)
