How to Build a Revenue Forecast That Your Board Actually Trusts

Bottom-up forecasting using pipeline data, historical conversion rates, and cohort-based expansion projections.

Board-level revenue forecasting requires accuracy and transparency. The model should show exactly how the number was derived, what assumptions were made, and what risks could change the outcome.

The bottom-up approach starts with current pipeline: weighted by stage probability, adjusted for historical stage-to-close conversion rates, and discounted by age (older deals close at lower rates). Then layer in expected new pipeline generation based on marketing and sales activity forecasts, and cohort-based expansion revenue from existing customers.
