this is the only application that I can fill in the Appraisal forms on my Mac Pro. the other softwares are just for Windows based programs. This does what the others do for less than half the cost.

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.

I received an auto-renewal subscription for our organization that was initiated by a previous officer and simply emailed my request for a refund and cancelation. I was contacted almost immediately by a **** ***** from pdfFiller/AirSlate that verified my information and resolved my problem. I had the money credited back within a few days. Thank you!

Simplified accuracy ! pdfFiller simplified and shortened the length of time; when I needed to complete filling out pertinent documents. My first experience with pdfFiller was when I had to do taxes. All the technical difficulties with filling out tax documents no longer existed. There are no Cons to specify, except my fears that this app is a "too good to be true" app. If you knew that before this app came along, PDFs were untouchable and un-editable.

I had a very complicated question pertaining to a credit card charge, (I didn't know which account within our company had incurred the charge, and therefore, couldn't track down a receipt) **** helped me reverse engineer the charge to find out where it came from. My company provides Customer Support for the Video Gaming industry, so I know the value of a positive CS experience. Way to Go, ****!
