Thank you for posting here in the Community, @Madonna_rph.

Any barcode scanner is compatible with QuickBooks as long as it complies this following format:

• Your scanner supports EAN-13 (International Article Number, formerly European Article Number) and Code-128 barcodes
• Your scanner produces a single carriage return at the end of the barcode.

Once your scanner meets the required format, you'll need to enable the barcode option on your QuickBooks Desktop. Here's how:

1. From the Edit menu, select Preferences.
2. On the left pane, scroll down to Items and Inventory, then go to the Company Preferences tab.
3. Select the Advanced Inventory Settings.
4. Go to the Barcodes tab, choose Enable barcode, then select Open Barcode Wizard.
5. Decide if you want QuickBooks Desktop to create new barcodes for you.
6. Select Next and Finish, then OK on the wizard windows.
7. Select OK twice to close the Advanced Inventory Settings and the Preferences window.
