Good morning, @liluic2020-gmail.
It's great to see you back in the Community. Let me share some insight into your question.
The best route would be to use the DocuSign eSignature Connector by QuickBooks app. This app is only available if you have QuickBooks Online Advanced.
I recommend reviewing the details of what this app can/can't do so you can see if it's right for your business. You can always look over the apps to see if there's another one that would work better for you as well.
You can either go to the direct website or review the apps in your QuickBooks Online account through the Apps tab on the left-hand menu bar.
I hope this helps answer your question. I'm only a post away if you need me. Take care!
