I need a barcode producer and scanner app for my QB online. Can anyone recommend one?

Hello there, @pax7and5. 

Thank you for taking the time to post in the Community. I can share more details about inventory management in QuickBooks Online (QBO).
 

It would've been great to have the barcode scanner in QuickBooks Online.  Meanwhile, we can look for a third-party application to help use the barcode scanner and add products to a particular transaction within QuickBooks. 

For more information about inventory management, you can check out these articles:

• Add inventory products in QuickBooks Online.
• Use reports to see your sales and inventory status. 

Let me know if there's anything else I can help you with. Take care.

You can utilize an inventory management app and your mobile phone as the barcode scanner.
