I thought I was purchasing a one-month subscription (I didn't select the correct button prior to the check-out process and was not advised of the amount before I hit Submit). Would REALLY like a refund of the yearly subscription - am very happy to pay the19.99 for one month. Please...

It was hard to figure out how to get started, and I made some mistakes in the beginning. I saved two files too soon and now I don't know how to erase them because when I try it says if I delete it it will no longer be shared. Is it okay to delete it anyway?

Had similar capability on work computer(s)> I was fine with filling out PDF files and saving them. Ths allows signatures and other features that may get me to keep it.

The user interface takes some getting used to after using DocuSign for 8 years. However, the customer service is second to none and has made the transition as smooth as I could have hoped for! Top notch to say the least!

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.
