Formula To Forecast Inventory (FFI) is a business tool that helps to predict future inventory levels. This forecasting method can help organizations anticipate how much inventory their business will need in the future, and how and when they should reorder items in order to meet customer demand. FFI relies on historical and current data to formulate predictions based on trends and regular cycles, helping companies create an efficient system for stocking inventory and managing their supply chain. It allows companies to plan ahead, saving time and money while ensuring customers are always provided with the products they need.
