Retailers need timely replenishment to maintain sales and satisfaction. Demand forecasting supports automated replenishment by predicting which products will sell, and when. It ensures shelves are stocked appropriately—neither overfilled nor bare. Among the six benefits of demand forecasting, improved replenishment stands out for its impact on customer experience. It reduces out-of-stocks, boosts sales, and cuts markdowns. Forecasting-driven replenishment helps retailers meet expectations consistently, improving brand loyalty and operational performance.
