Hello there, dkeiner.
I've got the steps on how you can disconnect the square app.
Connected third-party applications should show in the My Apps section within QuickBooks Online. Here's how you can un-sync (disconnect) with Square:
- In the left navigation, click Apps.
- Select My Apps.
- Locate Square Reader.
- Click Disconnect.
Once Square is disconnected, it will stop importing transactions.
For future reference, you can visit this link to search for other third-party applications that would work best with your business: QuickBooks Apps.
Please feel free to get in touch with me here for any additional questions about the connected applications to QuickBooks. The Community always has your back.
