B2B SaaS Forecast Spreadsheet

I’ll supply an outline of our current expenses and a short overview of the business; what I need back is a flexible Excel model that lets me stress-test our go-to-market plan. The workbook must allow me to plug in fresh assumptions at any time and instantly see how each change rolls through to top-line sales, operating costs, and customer-acquisition spend.

Core requirements
• Dynamic inputs for revenue projections, operating expenses, and customer acquisition cost
• Built-in toggles or separate sheets for a Worst-Case and a Most-Likely scenario, with the logic clearly documented so I can later add a Best-Case if needed
• Clean summary dashboard that updates automatically—charts, key ratios, break-even points, and month-by-month cash impact
• Clear separation between input cells and calculated cells; no hard-coding in formulas
• Well-labeled tabs, consistent formatting, and concise instructions so anyone on the team can maintain the model

Acceptance criteria
1. I change a single input (e.g., churn rate or marketing spend) and see the resulting revenue, CAC, and burn-rate adjustments across all scenarios.
2. All formulas trace correctly; no circular references unless they are intentionally iterative (and then they must be explained).
3. File opens without errors in the current version of Microsoft Excel for Mac and Windows.
