If Sellar has to create a new customer on Xero, we pass along the following details. This happens the first time you process an order for this customer:

Therefore, we provide settings which allow you to choose how you’d like to handle updates to customer information. You can choose whether you want Sellar to update your contact’s details in Xero or not. Head to the Xero integration page to configure.
