A customer order sets a chain of activities in motion. Order fulfillment is the end-to-end process of receiving an order, reserving inventory, picking, packing, shipping, and confirming delivery.

It spans systems and physical operations: order management software, warehouse execution, carrier selection, and proof of delivery. Cycle time from order capture to shipment determines how fast customers receive goods. Exceptions—stockouts, address problems, payment holds—must be handled without losing the order.

E-commerce has compressed fulfillment expectations to days or hours. Omnichannel models add complexity by fulfilling from stores as well as warehouses. Reliable fulfillment is the operational translation of a sales promise.
