Demand forecasting uses historical sales data and market trends to predict future customer demand, enabling retailers to optimize stock levels and reduce excess inventory. Inventory planning focuses on managing stock quantities, reorder points, and safety stock to ensure product availability while minimizing holding costs. Explore the link between demand forecasting and inventory planning to enhance retail operational efficiency.
Why it is important
Understanding the difference between demand forecasting and inventory planning is crucial in retail to optimize stock levels and reduce costs. Demand forecasting predicts customer demand using historical sales data and market trends, enabling more accurate purchasing decisions. Inventory planning uses this forecast to manage stock quantities and timing, preventing overstocking or stockouts. Accurate coordination between these processes enhances supply chain efficiency and improves customer satisfaction.
