Cheers to your incoming retail outlet, Raynorshine!
At the moment, the QuickBooks Point of Sale program is only offered in the United States.
I'd suggest finding a third-party app with POS function and integrate it to your QuickBooks account. Just click the Apps menu in the left navigation bar and search for something like POS, payments, etc. You can also click on Browse category and select Payment Processing to see the list of apps under it.
