ShipHero Fulfillment can scan serial numbers on products during packing to track which serial numbers leave the building with which orders. This is a special feature that must be requested during onboarding. It is $0.25 per unit scan for products that require serial number tracking.
The serial number must be visible on the product packaging; either as an SN barcode (separate from the product SKU barcode) or just a number printed on the visible packaging.
