Well I paid for the year then could not access a file I did the same day. Then I sent my accountant a file via attachment since he says "not technical" & could not open it in pdfiller file, so I sent as attachment so he could complete but he could not so he wrote it in now I have to complete it & paying him the same.

Easy to use, unlike other fill and sign apps, it can tell the right size text. It can tell the what parts of the document requires the text. The variety of templates to use for common forms needed for most people. Also a generous 30 day trial A ++++

Great Product And Support I have used pdFiller for several years and loved the product. It is a great product and great value as well. I only had to deal with customer support once and had a 10+ experience. Sally was terrific. I would recommend this product to anyone who deals with a lot PDF files. And the customer service is #1.

I absolutely love, PDF filler. It is so easy to create forms whether I use them as fillable or not, they are terrific. I love that I can name each form and save each form. It's so easy to print my new forms. I'm actually having the time of my life creating them, it's actually fun I know no one else is probably going to say that but I think it's really fun to use. I am 59 years old and this is better than Etch-a-Sketch back in the day and that says a lot lol I would highly recommend pdfFiller to anyone and I have. I own 3 medical practices and we have forms forms and more forms. PDF filler has been just an absolute lifesaver. I've also use it for personal forms that I need. I haven't had a need to use any of the pre templates that are available. I'm just so thrilled that I found pdfFiller. I actually purchased two Remarkable tablets for my practice and that was a disaster. It was an unremarkable purchase to say the least. It's just not that great when it comes to creating a beautiful document, it just wasn't for us. So glad that I went on Google and found pdfFiller. I am happy business owner! Thank you.
