Forecasting Basics: Build a Plan You Can Actually Run

Forecasting doesn’t need to be fancy. Start with assumptions you can measure, a simple funnel view, and a weekly review loop to correct course.

Start with assumptions, not spreadsheets

Forecasting is just a set of assumptions tied to observable inputs. If you can’t measure the inputs, the forecast will turn into a story instead of a tool.

Use a funnel view

Track a few numbers: leads created, qualified leads, proposals, closed-won, and average cycle time. You don’t need perfection—just consistency.

Review weekly

A forecast only helps if you revisit it. We recommend a short weekly check: what changed, why it changed, and what you’ll do next (pipeline, follow-up, marketing, or capacity).

Tie it to operations

The best forecasts inform action: staffing, delivery capacity, marketing spend, and follow-up cadence. When forecasting is connected to ops, teams stop reacting and start steering.
