GUESS? replaced a single overloaded Los Angeles DC with a multi-site network including Louisville, Montreal, Hong Kong, and Shanghai. Manhattan Associates Warehouse Management enabled real-time inventory tracking, multi-channel order segregation, and integration with host systems Jesta and JDA. Results included 83% reduction in inventory cycle time, 30-40% annual shipping growth, and $1.3 million annual handling cost savings.
