Create a new customer invoice.
Consider converting an Order to an InvoiceIf you are working with orders in Rackbeat, then you should convert order to invoice instead of creating an invoice from scratch. By using the convert endpoint a link between the order and the invoice will be created.
Similarly you can also create an invoice from the shipment of an order, so that you keep the links between the order, the shipment and the invoice.
