Most revenue budgets start with a top-down number: add 10%, push sales harder, and hope the math works out. That’s why so many plans collapse by spring.

In Part 3 of our Budget Season 2026 Series, I sat down with Kim Clark to break down how to build revenue the right way: from the bottom up. Kim shares her 12-step revenue forecasting process and shows how to build by product, segment, and pipeline. We talk about aligning sales, marketing, and operations so the plan is deliverable — and how to connect the revenue build-up directly into the budget model from Part 2.
This isn’t about sales stretch goals or wishful percentages. It’s about creating a clear, defensible revenue plan that finance can trust and owners can use to make boardroom decisions about hiring, capacity, and cash.
In this episode, Kim and I screen-share and walk through the 12 steps. If you want to see the forecast in action, check out the video version on YouTube or Spotify.

What We Covered

• Top-down vs. bottom-up forecasting → why most owners default to “just add 10%” and how that fails.

• Kim’s 12-step process → very tangible, step-by-step structure owners can follow.

• Revenue build-up mechanics → segments, products, pricing, pipeline, win rates, seasonality.

• Operational alignment → connecting sales, marketing, and delivery so revenue forecasts don’t break capacity or margin.

• Integration with Pat’s model → feeding clean revenue assumptions directly into the budgeting model.

• Trust & credibility → how finance, leadership, and owners can finally use the same numbers and stop arguing about “whose forecast is right.

Kim Clark is a sales and marketing strategist who helped scale ITR Economics from a founder-led advisory firm to a professionally managed company that exited at eight figures. As head of sales and marketing, she built the firm’s first CRM, content strategy, and inbound engine—moving the company from personality-based selling to a system built on data, automation, and strategic execution. Today, she works with business owners to build marketing engines that align with their strategy, team, and long-term cash flow goals—so they can grow without chaos and delegate without losing visibility. Her frameworks are directly aligned with the "Predictable Revenue" module within the iBD Ownership Operating System.
