When new a order is fulfilled in your Squarespace store, Integromat will automatically retrieve the order and create an invoice with Xero. If it's a new customer, a contact will be created in Xero first. Please note, Xero does not allow contacts to have the same name for security purposes.
This is a predefined template that will make the creation of your scenario much easier. Of course, you can always expand and customize the scenario to meet your own individual needs.
