• Another effective technique involves leveraging automated data collection methods.
• Both methods have their advantages and disadvantages and should be evaluated carefully before making a decision.

The bottom-up approach starts with the sales team providing estimates for each product or service. This estimation takes into account the historical data, market trends, and customer feedback. The individual sales estimates are then consolidated into a single projection for the entire organization, a product line, or a region.

This methodology relies on detailed analysis of individual sales activities, pipeline stages, and sales rep performance to create an aggregate forecast. Top-down forecasting also requires intense research and analysis on the market, understanding its trends and what attracts people’s attention, and what improves sales.

Especially the inventory that contains data about the products or services. Large organizations, for example, have historically tended to lean toward the bottom up method for forecasting sales top-down forecasting due to the sheer amount of data that would need to be collected and analyzed for a bottom-up approach. Of course, modern demand planning software and other platform tools have eased this challenge. Revenue forecasting is an essential part of any business’ financial plan.

The type of data you have available plays a big role in which forecasting method might be best for you to use. For example, if you have data with limited detail (say, you’re entering a new market with little historical information), top-down might be a good starting point. But if you have robust, granular data about individual products, bottom-up forecasting can likely provide a more detailed and accurate picture.
