What is Safety Stock?
Safety stock refers to the additional quantity of inventory maintained by a company to mitigate the risk of facing stockouts due to unexpected fluctuations in demand or supply chain disruptions. It serves as a buffer or insurance against uncertain circumstances that could lead to delays in replenishing inventory levels and ultimately impact customer satisfaction.
Inventories play a critical role in ensuring uninterrupted supply to customers. However, predicting consumer demand accurately can be challenging, especially when unforeseen events occur. In such situations, safety stock acts as a cushion, allowing businesses to meet customer needs promptly, even if actual demand exceeds the forecasted quantity. By having safety stock, companies can prevent stockouts, minimize lost sales opportunities, and maintain a positive brand image in the market.
