Currently, we're unable to link Chamber Master with QuickBooks Online. You'll want to check other applications that can integrate with the system, please refer to this link: QuickBooks Apps.
In addition, here are the supported Apps by Intuit and Partner support.
As always, feel free to comment if you have additional questions. I'll be around to help. Stay safe and well.
