In the world of supply chain management, it’s crucial to distinguish between Sales Forecast and Demand Forecast:

Sales Forecast: A sales forecast predicts the amount of product your company expects to sell within a specific period. It is typically based on historical sales data (actual invoices), market trends, and input from the sales team. The primary goal of a sales forecast is to set realistic sales targets and align production with expected sales. However, sales data can be biased as it’s based on historical invoices and open customer orders, reflecting only what has been sold and ordered, not the potential demand that couldn’t be met due to stockouts and low service level.

Demand Forecast: In contrast, aims to predict the true market demand for products, considering factors beyond just historical sales data. It is a more comprehensive approach that integrates various inputs to estimate future demand accurately.

Key Difference: Forecasting Focus

• Sales Forecast: Centers on setting sales targets and planning production based on historical sales and current orders. It provides a snapshot of expected sales but can be limited by its reliance on past data.
• Demand Forecast: Focuses on predicting genuine market demand by analyzing a broader range of factors. It aims to provide a more accurate picture of future needs, enhancing inventory planning and decision-making.

Common Pitfall: Over-Reliance on Historical Sales Data

A common pitfall in forecasting is the over-reliance on historical sales data. While sales forecasts are grounded in actual invoices and customer orders, they often fail to account for missed opportunities due to stockouts or other inventory constraints. This incomplete view can lead to inaccurate demand planning and suboptimal inventory management.

Understanding these differences helps businesses streamline their operations and meet customer demands more effectively, ensuring a balance between supply and demand.
