As a Realtor I am constantly having to merge PDF files, or fill in forms, or add notes to contracts, or rotate pages from horizontal to vertical. My hand writing is not very legible, but PDFfiller makes all of my docs look professional.

Love it- so easy- wish there was a cheaper option for "stay at home moms" (could verify with a phone call) - since all I tend to use it for is school forms and household paperwork

It's easy to work with. Wish there was a "clear all" button so that I wouldn't have to close and open back up to start a new form, but overall, great product

Exceptional customer service Kara was of great assistance working through my billing question today. She was quick to respond and went out of her way to explore all avenues before I realized that the expense about which I was inquiring was charged by another company, not pdfFiller. She was extremely polite and patient.
