Good day, NDR.
Let me give you an overview about the third party applications and how it works in QuickBooks Online.
The information we receive is dependent upon the third party application, which is the Square App.
With regard to the integration and import process while tracking inventory, I suggest that you reach out directly to Square. They can give you accurate information and sort the issue immediately.
Also, you might want to check out with the third applications that QuickBooks Online integrate. Please refer to this link: Sync with Square Hub.
Fill me in if you have any other questions or clarifications. I'll get back to you the soonest. Happy Holidays!
