Makes pdf edition easier In our office we need to fill a lot of IRS, FDOR and Court forms. This software allows us to fill them and save them a feature most of the governmental entities don't allow us. It also allows us to erase and edit all pdfs which makes our lives easier. It also allows you to load a document from every possible location, even has its own data of forms. What I don't like about this software is that in order to go to the next page you can't roll down you have to switch pages and sometimes I end up missing a page of the document.

Excellent Saves me from taking up so much of my memory on the office computers. Easy access and you can edit your documents anytime. It is very handy and you can save your work plus be able to edit your documents at a later time.... need to be able to tab from filler boxes and be able to automatically type in the boxes without having to add text boxes

Fabulous addition for the office!!… We added this for our company in the office as a tool to try out and make things easier. Honestly I have used it far more than I thought. No more printing out anything to fill out and sign it and then scan it back and send it. You can upload and fill in the spaces, check any boxes and sign it, save it and email it right over, and it looks so much more professional too.

Great services with an excellent customer care policy I enjoyed great services provided by pdfFiller through an annual plan. I used their service in all my dealings with pdf documents. Then for professional reasons, I had to cancel my subscription, and pdfFiller team was extremely kind in offering me a full refund of my subscription fee. Just after 3 minutes of sending them a message, they responded back explaining the details of my refund process. That is what I call a great customer care and professionalism! Once again thanks a lot!

Easy to use. I have to STUDY the layout to find what I want. We are not power users of this product. The webinar might help. The pricing you impose presumes that I use a lot of features. I wish you had a price structure to low end users who seek to have a few simple forms filled and signed.

Ryan on the Support Team was extremely helpful and patient. He walked me through all of the steps to complete the form to my satisfaction. Thank you Ryan for teaching me!

Best part of the service is responsiveness to online support, but there are a few minor glitches that should be addressed. I'll elaborate later when time allows for it.
