The functionality to automatically connect Stripe to QBO is unavailable at this time. You can consider using a third-party application to integrate it.
While I'm unable to personally recommend which program you should use, I can help run a search to find one. I invite you to visit the QuickBooks Apps site to look for a supported app.
Aside from that, we have designed the Apps center within QuickBooks Online to show you recommended third-party apps suitable for your business.
To access it:
Tap the Apps menu on the left panel and then enter a keyword in the Search field.
This will display a list of programs that you can use.
Click on it to view more information.
I don’t want to leave you empty-handed, so I’m adding a link containing a breakdown of articles on the processes you can perform in QBO: Self-help articles.
Keep me posted if you have any clarifications or concerns. I’m more than happy to answer them for you. Enjoy the rest of the day.
