Occasionally, your Customers will ask you for a tax invoice.
As Catch is a Marketplace, we are acting as an agent for the sale.
The merchant of record is, therefore, the Seller on the Marketplace.
As the official seller, you are required to provide an official GST tax invoice when requested by a customer.
All orders that you receive detail the total amount paid by the customer - this is the figure that should be invoiced to the customer.
The commission on the order is also specified, this should be viewed as a cost of the transaction.
The commission amount should not be detailed separately in the invoice
