I am older and my hand shakes so badly I cannot fill in forms -- it is a real life-saver, not to mention time-saver. I don't have to call someone in to fill the forms out for me, I've already recommended PDFfiller to a dozen friends!

This is my first attempt at using your system but so far so good. I'll answer other surveys later after I have had some experience with the system. It takes a little experience to use the system easily. You could use more instructions. Perhaps a start guide on how to perform various manuevers.

Easy way to fill out. Don't have to print and scan. Very clean. I liked the signature filler. Just uploaded and place wherever there's a signature and shows up with PDFfiller date stamp

Great Program to help buyer's get their electronically signed documents It makes it much easier for the buyer to get documents that can be electronically signed. Quality of the documents that get sent to my buyer's is fantastic. The look of the documents are professional quality Ease of use. It is hard to remember how to set up the file to get to the buyer quickly. I always have to try it 2 different times to get it right.

AMAZING CUSTOMER SERVICE - JED I have been conversing with the support agent called Jed, and he has made my vision of this company very clear. Supportive, constructive and quick with the aim to please. He has dealt with my query in such a fast and efficient way that is was delightful to receive a response from him. I just want to thank Jed for the amazing customer service received by him and I surely hope his company sees this and praises him. @PDFFILLER

IRS changed the 1099 misc form IRS changed the 1099 misc form, so I had to find an alternative access to the 1099 misc form that showed non employee compensation. The 1099 NEC form was the form I needed. A new bokkeeper will handlethis from now on. Thank you
