What is cross-docking?

In a cross-dock flow, the pallet that comes off an inbound truck is sorted and loaded onto an outbound truck within hours, skipping the putaway-store-pick cycle entirely. Retail distribution centers cross-dock store-bound goods that are pre-allocated before they arrive; parcel networks are essentially cross-docks; and distributors cross-dock special orders where the customer is already known when the goods land. The gains are real: no storage labor, no bin space consumed, no second touch. The requirements are equally real. Cross-docking only works when the destination is known before arrival, inbound timing is reliable enough to coordinate with outbound, and the receiving record happens fast, because the goods won't sit still long enough for a leisurely check-in. The record-keeping subtlety: goods that never hit a bin still have to hit the books. A cross-docked shipment must be received against its PO and shipped against its order, even if the physical interval between those events is forty minutes. Operations that skip the receive step because "it's going right back out" create POs that never close, inventory that was owned but never recorded, and a three-way match that fails months later. For most small operations, the everyday version is humbler: the special-order item for a waiting customer gets received and staged for pickup rather than putaway. Same principle, one pallet at a time.
