As a small business owner in the healthcare field, we do not have the resources to have much administrative support. PDFfiller's user interface helps us with the host of insurance forms that are emailed to us. We simply download them in to PDFiller and our forms look professional and they are easily accessible to save or send back completed and signed.

I've been able to recreate documents into templates and this way it is easy to fill out when they are used repeatedly. I also like the signature part makes signing docs very handy. I haven't used, but am excited about the notary part that was added.

Great! Online - I like accessing it anywhere, at any time. Great! I will keep my membershup for some time! Not sure of security, not sure how my information is being used, if someone else is analysing it, etc.

Allows me to fill in pdf documents with computer so I don't have to print out and fill out manually. Not sure why text moves to next line below in some cases.
