The stat underscores the volatile environment in which fashion forecasting operates.

Fashion Demand Forecasting Ecommerce Statistics #12 – Poor Forecasting Causes Excess Inventory Or Frequent Stockouts

When forecasting accuracy is low, businesses face the dual risks of overstocking or stockouts. Overstocking ties up capital and often results in heavy discounting. Stockouts, on the other hand, damage customer trust and loyalty. Effective forecasting balances this equation to sustain profitability. The stat highlights the consequences of inadequate forecasting systems.

Fashion Demand Forecasting Ecommerce Statistics #13 – Models Including Returns And Uncertainties Outperform Simpler Models
