Using iPhone to complete apps and send out for signature.. Had some glitches.. Wasn't able to select or choose (full access or sign only option for recipients. The screen shut down too quickly each time and 'disappeared before I could actually select.

While I understand that you want to get subscriptions for a whole year and renew those subscriptions annually, I would prefer to have an invoice at the end of the year, so that I could decide if I wanted to continue using your service or not. I really resent automatice renewals. Hence I went with the month to month as my need for your program may only be for a short time.

PDF filler has replaced my Adobe Acrobat because of how easy it is to use and it's functions that match my business model. The unlimited filler links are extremely helpful for my clients. The ability have the html coding for each link, the mass link / excell options and the ability to sell my forms. It is a life saver!

What do you like best?
Ability to add notes to PDFs for my clients. It really does help answer questions for them much faster and help them understand the document better.
What do you dislike?
I wish I could merge and rearrange documents without it costing more to upgrade to do so. Would also be nice if If could set two password when securing a file. One for client and my master password
What problems are you solving with the product? What benefits have you realized?
Being able to mark up pdf documents for my clients that otherwise I could not. I like the pen option to call out important numbers for them to review. Being able to highlight where there signature is needed is an added plus
