I have used the free trial twice. When I signed up for a $6 one month personal subscription I was billed $20USD. I have sent an email about this and hope to have it resolved.

Worked just as it promised when I looked the app up and read about it. It's a little pricey though as I can go to Adobe's online app for $9.99. Why the big difference?

I like the concept, but slow I like the concept. But the processing is awfully slow. I'm going to buy a membership for my team, but I just wish everything processed more quickly.

What do you like best? How easy it is to access all documents and edit previous documents What do you dislike? I wish there were more tools to help edit, such as cropping a document or resizing What problems are you solving with the product? What benefits have you realized? It usually takes a while or is difficult to edit a document, but with PdfFiller, it's easier and faster. I can take a form I often use, and instead of entering the information every time, I can change the date

useful, easy, accessible, and most of all which is rare in these cases transparency ( love that you show days left of trial rather other free trials that sneakily start charging hoping you forget when trial ends and not respond)
