A system function that temporarily allocates specific inventory quantities to fulfill pending orders or planned activities, preventing that stock from being assigned to other transactions until the reservation is released or fulfilled. This process ensures accurate inventory availability calculations and prevents overselling by creating a “soft hold” on designated items.
Inventory reservation is critical for maintaining order fulfillment accuracy and customer satisfaction, especially in high-volume operations with multiple concurrent orders. It enables warehouses to commit inventory to specific orders while maintaining real-time visibility into available stock levels. For example, when a customer places an online order for 50 units of a product, the WMS immediately reserves those units from available inventory, even before picking begins. This prevents the same inventory from being allocated to subsequent orders, reducing stockouts and shipping delays. Reservations typically remain active until the order is picked, shipped, or cancelled, at which point the inventory is either consumed or released back to available stock.
