Great to see you in the Community, @plumber123.
Currently, the Quick Plumb is not integrated with QuickBooks Online. Although, you can find other Plumbing App that is already integrated. Or you can ask Quick Plumb to do an integration with QuickBooks.
You can give this link to their support team so that they can start the application for integration with our Product Developer department: https://developer.intuit.com/app/developer/homepage. Let them create a developer account and submit a request for integration.
For now, you can check out this page to see the available plumbing applications: QuickBooks Apps. Log in to your account and enter a keyword on the search bar. Look for the app that would fit your needs by checking the App's overview and features.
You're always welcome to tag my name if you have other questions. I'm here to back you up. Enjoy the rest of your day!
