Definition

Safety stock is a reserve inventory that businesses keep on hand to protect against uncertainties in demand or supply chain disruptions. It acts as a buffer to ensure that a company can continue to meet customer demand even when unexpected events occur, such as spikes in demand or delays in replenishment. Properly managing safety stock is crucial for maintaining service levels while minimizing holding costs.
