E-Sign Service

I am looking to start using a e-Sign service in the coming tax season.

I use Drake. They have an integrated e-Sign service. If anyone of you have used this service before, please give your comments.

Any good alternatives that I can consider?

Depending on your budget, you may want to consider DocuSign.

If you use Citrix ShareFile, you may want to consider RightSignature.

I have been happy with DocuSign. I have it through SmartVault and I can still do basically everything I can do if I had a higher level subscription via DocuSign direct. I was looking at some alternatives to DocuSign and have previously used RightSignature; prefer DocuSign overall. Biggest thing is make sure the service can use Knowledge Based Authentication. Not all e-sign services offer that capability...
