Safety Stock
Safety Stock is a basic concept in inventory management where companies keep extra products or materials on hand, beyond what they normally need. Think of it as a backup supply that helps businesses avoid running out of items when unexpected things happen - like delayed shipments, sudden increases in customer orders, or supplier problems. It's similar to keeping extra food in your pantry just in case you can't get to the store. Many companies use this approach as part of their inventory management strategy, alongside other terms like "buffer inventory" or "reserve stock."
