pdfFiller scores top ratings on review platforms
I am glad to have this filler. At my school we are trying to go paperless. It is expensive. Sometimes hard to maneuver and cumbersome to use. Once I get the hang of it and use it more often I am sure I will become more adept at using the filler.
I like using the program the only downfall for me is unless I pay more for the subscription I'm not allowed to use the premier options. That is my opinion It's already expensive for me since I really only use it for tax returns.
