Sales forecasting techniques are methods used by businesses to predict future sales performance. Common techniques include historical sales analysis, where past sales data is examined to identify trends, and market research, which gathers information about customer preferences and market conditions. Another approach is qualitative forecasting, which relies on expert opinions and insights, while quantitative forecasting uses statistical models and data analysis. These techniques help companies make informed decisions about inventory, staffing, and marketing strategies, ultimately aiming to improve profitability and efficiency.
