We use a third party solution (Stitch Labs) for our marketplace order management. Currently the Stitch Labs order number is passed to ShippingEasy, which is fine for processing and shipping orders. However, when the customer receives the shipping confirmation through ShippingEasy, the order number is the order number assigned through Stitch Labs rather than their marketplace order number.
In Stitch Labs the marketplace order number is in the "Reference #" field. It would be great if we could re-assign what field supplies the order number to our customers to avoid confusion.
