pdfFiller scores top ratings on review platforms
This is the greatest help to any business....I am amazed how user friendly and professional this makes for any business large or small. WOW ! Hats off to PDFfiller.
Very versatile software for editing (specifically filling in) PDF documents. I looked specifically for software to fill out tax forms and PDFfiller exceeded my hopes and expectations. Good job.
I found PDF filler to be very helpful, however there was a bit of confusion with the cost of the account account. I I thought that I would be getting charged $6 dollars per month however my bank account was charged $72 dollars for an entire years subscription. I do not fill out enough documents to make a years subscription worthwhile. If that is the case, I think the website should give you the option of a 30 day trial period, and then give you the option of committing to a 1 year subscription. Otherwise, be more clear that you all are charging the entire $72 as oppose to the $6 per month. I have since canceled my subscription and I do not intend to use the website any longer. I would definitely like a refund effective immediately.
So far it works great! There's a bit of a learning curve, but I was able to chat with a support rep even though it was late at night. He helped explain how I could achieve my goals for our Robotics team engineering notebook forms.
Very helpful tool for 1099. How do you auto populate though. I find it tedious to manually type the same info over and over. Still WAY better than the alternative though. Thanks.
Confusing to learn and there is a lot to learn. There is no simple way to learn that I can see . I contacted support but it is only a way to answer one question at a time . While I might recommend it to someone , it would be with caution about how complicated it is
Excellent Customer Service
