Hi there, @sugarcube.
I'll share insights about how app integrations work in QuickBooks Online so you can sync your sales transactions accordingly.
Here in the Community, we don't have a direct view and access to any of the applications integrated with QuickBooks. With this, I recommend contacting the Technical Support of Shopify.
From there, one of the specialists can help and share the steps needed to map the accounting preferences and generate your sales activity. You can view the contact information of your app provider by checking it under the App Information section.
For all the features and functions of QuickBooks, you can log in to any of our supported browser versions and use this reference for guidance: Help Articles in QuickBooks Online. Also, you're able to read subtopics that will describe how a feature is used and how to accomplish tasks related to its functions.
Let me know in the comments if you have any other questions aside from working with applications in QuickBooks. Use the Reply option below to leave a comment and don't forget to include my name, @JonpriL. Take care always, @sugarcube!
