Important: Once a Xero organisation is linked to your Retail POS account, it cannot be changed. You can remove a Xero organisation from Retail POS, but you cannot then link a different organisation to the same Retail POS account. This is because all past account sales, register closures, purchase orders, and customers in Retail POS will remain linked to the original Xero organisation you set up. If you have any questions about this, please contact our support team.
