QuickBooks  does not have a built-in feature to track detailed inventory locations within a warehouse directly on the item card. It primarily focuses on overall inventory counts and financial transactions.

However, you can implement a third-party solution like Cleverence Warehouse 15 to manage this. Cleverence Warehouse 15 allows you to track inventory locations, print labels, scan barcodes, and sync this data with QB. This means you can manage inventory locations effectively and have accurate data in QB.

Cleverence Warehouse 15 provides mobile functionality to handle inventory operations right where they happen, and this data is integrated with QuickBooks, keeping your inventory information up-to-date.

For more details, check out: Cleverence Warehouse 15.

This approach ensures you have a complete picture of your inventory locations and improves overall inventory management.

For now we have only QBO Global customers and implementations, I'm not sure about US ones.  So yes, it does support QBO Global version.
