What do you like best?
As a Realtor, my whole business is based on electronic documentation. PDF filler is kind of named poorly, because it really is a PDF editor. It allows you to easily change almost anything on a pdf document...across both desktop and mobile platforms. It simply works as you'd expect it to...every time. I use it practically every day.
What do you dislike?
I wish there were better tools for generating lines (how about a toggle into and out of orthagonal for a line?) It should allow deeper zooming with a thumbnail view showing where you are in the overall document. I like my pdfs to look perfect and sometimes these limit me in that goal.
What problems are you solving with the product? What benefits have you realized?
A Realtor literally lives or dies on his/her electronic documentation. This tool lets me master the changes that inevitably occur with documents. I use it every day.

What do you like best?
I love the ability to make my own PDF Templates. It is the perfect insurance agent tool when you're doing multiple certificates of insurance for commercial customers during renewal time. I love the feature where I can e-sign the documents and save it as a PDF which saves me ink and paper.
What do you dislike?
I can't figure out how to combine 2 PDF'S and merge them together so I use a different program for that.
Recommendations to others considering the product:
A must have if you're in the insurance industry
What problems are you solving with the product? What benefits have you realized?
It saves us time by creating templates, super helpful when it comes to creating multiple PDF's for our customers.
