Hi there, @productionszani,

The barcode scanning for inventory management is already available in QuickBooks Desktop.

If you need to set up and use this feature, you can go through this article for the detailed steps: Use barcode scanning.

While you can't use this feature in QuickBooks Online, you can visit the Intuit Apps center and search for available apps to scan your inventory.

Thanks for reaching out to us here in the Intuit Community. If there's anything else I can help you with, please let me know. I'm always glad to help.
