Preventing a stockout is one of the primary objectives of inventory planning. A stockout occurs when available stock for an item falls below zero effective supply – current demand exists, but the product cannot be shipped. The item remains part of the product range; it is simply unavailable at that moment. Consequences range from delayed shipments and lost sales to reputational damage; for fast-moving consumer goods or production components, even a brief stockout can halt manufacturing lines. Logistics providers counter this with safety stock, reorder points, and automated replenishment triggers. A stockout differs from a permanent range discontinuation, where an item is removed from the assortment entirely.
