A pipeline forecast is the process of predicting future revenue based on the active deals in your sales pipeline. It evaluates deal value, stage progression, probability to close, and expected timing to estimate how much revenue is likely to land within a given period. Unlike traditional sales forecasting, which leans heavily on historical performance and averages, pipeline forecasting reflects what is happening right now across your open opportunities. That makes it one of the most important tools for short-term planning, revenue visibility, and sales accountability.
