What is Sales Forecasting?
Sales forecasting is the process of predicting future sales performance based on historical data, market trends, customer behavior, and economic factors. These forecasts help organizations estimate how much of a product or service will be sold within a defined timeframe, whether monthly, quarterly, or annually.
Rather than guessing future performance, sales forecasting provides a structured framework for anticipating demand, managing risk, and aligning operational strategies with realistic revenue expectations.
