It is a little hard to learn and it is a little expensive, but it is the best "filler" program I have ever used and I am glad and grateful to have it.

My handwriting seems to get worse with age and in this world of no typewriters for forms that need to be readable I have at odds when it comes to filling out many of todays forms. To date PDFfiller has proven to be a god send for my dilemma.

This is my first experience with online documents and I had a difficult time maneuvering through the settings. Would like more information on how to use.

Was not sure about the monthly versus the yearly and almost paid too much! In my opinion: There should be an option for businesses with more than one licensed user to have access too, versus giving out my personal login so my partners can benefit from the same resource. Such as a link where up to two are licensed and covered and then the rest have to get their own subscription.

Have had very limited issues with this application, and when I did have a problem the chat service was expedient and very helpful and resolving the issue

Quick and easy refund
I had excellent customer service after I was charged a monthly fee by error. The service response to my initial email was very quick; 3 easy, practical solutions were offered and following my choice my refund was processed very quickly.Very grateful.John

Really came through for me when I was charged a subscription fee. Being a small business owner, things get hectic. I had used it for my taxes and meant to cancel it but forgot. They cancelled my subscription and refunded the fee with no questions asked. Too bad it really wasn't a good fit for my business."

It's been great so far. I need to learn how to move around the dashboard quicker. Also, I need to learn how to set up individual folders (if applicable)?
