I'll share insights about barcodes in QuickBooks Online.
As of the moment, there isn't an integrated way to generate barcodes in QuickBooks Online. For now, let's consider integrating one from any of our third-party applications to generate and maybe include the option to scan barcodes.

Enter Barcodes in the Search text area.
Choose an app you wanted to use and check for reviews.
Click Get app now.
