Good day, @chris_gates.
I'm glad you've reached out to us. Let me help provide some insights about integrating Point of Sale (POS) with QuickBooks Online (QBO).
Any versions of QBO will allow you to track sales and payroll information for your employees when integrating the POS. However, if you process inventory and bills, you'll need to use the QBO Plus version.
For additional reference, you can check this article to learn more about POS integration: Let your POS system and accounting software do the work for you.
You may also check this link to know more about the features in different versions of QBO: https://quickbooks.intuit.com/online-compare/.
Don't hesitate to leave a comment below if you have any other questions about the POS. I'm always here to help you out. Wishing you and your business continued success.
