PDFfiller is simple and easy to use. It gets the job done. Easy way to have paperwork signed. PDFfiller makes the documents look very clean and keeps me organized. Also it is not hard to figure out how to use it. The customer support is amazing too. There are no CC options when sending out a document for someone to sign. I hope PDFfiller creates that feature soon.

I like it very much, I think it has great fearures... I like it very much, I think it has great fearures and it has helped me a lot... so much that I was ready to become a paid user. However, 2 of the last documents I uploaded to the system were cut-off and seriously changed (different format, things missing, etc) the uploaded document did not show as an identical version of the original document and that made me change my mind. I use it for contracts and they need to be exactly as the original document. These are legally binding documents, so because of that, I decided not to continue the service after the free trial ends.
