Understanding Sales Forecasting
Sales Forecasting is fundamental to business planning. Companies rely on forecasts to determine production volumes, staffing needs, inventory levels, marketing spend, and cash flow expectations. Forecasts may be short-term (weekly/monthly) or long-term (quarterly/annually).
Forecast methods range from simple trend analysis to advanced machine learning models. Accurate forecasting reduces uncertainty, improves decision-making, and enhances operational efficiency.
