I got confused a couple of times when using PDFfiller, but their customer support was outstanding; they immediately responded and were very helpful. PDFfiller is a solid solution for filling out yearly tax paperwork on my Mac. I'll be using it every year now.

I am very impressed at the features, especially being able to combine pdf files and edit files. I find navigating to and from the 'My Forms' area a bit clunky. The 'save as' feature takes forever to achieve, too many steps for a file that is already created. For my business, it would be a huge benefit to be able to print out a confirmation page when my faxes have been sent and received. I like to keep such confirmations with the files as proof. All in all, I love the program and am thankful for such a convenient and manageable product.

Quite good! Quite pleased to know I can unmerge a PDF file and add/remove files and have my file properly edited. I need to learn more about the features.

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.
