Hi there, @StephanieL.
Thanks for getting back on this thread. Allow me to chime in and help provide clarification about using barcode in QuickBooks.
All QuickBooks Desktop versions have inventory to keep track of your inventory and receive alerts when it's time to reorder and create purchase orders. However, using barcode is only available if you have the Advanced Inventory feature which is in the Enterprise version.
Let me include the following articles for your reference.
Turn on Advanced Inventory
Use barcode scanning
You can try finding Desktop Apps that's previously mentioned by our established community backer @MJA66-87. Just ensure that it's compatible with QuickBooks Premier. You can search for the available 3rd party apps on this site: Apps for QuickBooks Desktop.
