Thanks for joining the thread, @BarbRogers123.

This time, QuickBooks Point of Sale (POS) can only integrate with the QuickBooks Desktop version. You'll want to look at another third-party POS application to combine with QuickBooks Online at our Apps Center.

I've also added articles about the details on how to integrate QuickBooks POS with QuickBooks Desktop:

• QuickBooks POS Syncs with QuickBooks Desktop
