Buffer Stock
Buffer stock (also known as safety stock) is extra inventory that companies keep on hand to prevent running out of products or materials. Think of it like having a spare tire in your car - you hope you won't need it, but it's there just in case. Companies use buffer stock to handle unexpected situations like delayed shipments, sudden increases in customer demand, or supplier problems. This practice is an important part of inventory management and helps businesses maintain smooth operations without interruptions.
