What does the shop want the product to do: Shop looking for a feature request that when the orders sync to ShipStation the UPC of the product should be sync along with the order because the shop can not use Shipstation's Scan to Ship feature if the UPC doesn't sync. It doesn't have anything to scan.

Why/how would it improve sales or efficiency: The "Scan to Ship" feature in ShipStation, the warehouse team can move from manual order searching to instant scanning. This reduces the time spent per package, allowing the shop to fulfill a higher volume of orders daily

Using UPC scans during the shipping process ensures that the correct variants are being deducted from stock.
