It's good to see you here in the Community, @amey-cdrstructur.
I'd like to redirect you to the best support group available to get this addressed right away.
QuickBooks allows integration with a number of third-party apps and software. Since you want to know how QuickBooks Online (QBO) and AdobeSign work, I recommend reaching out to AdobeSign customer support. They can provide further information about the integration with QBO.
As always, you can visit our QuickBooks Community help website if you need tips and related articles in the future.
Our doors are always open to help you again if you have follow-up questions about integrating third-party applications in QBO. Have a good one.
