A financial model is a story told in numbers. Three sheets:
- Assumptions. Customers, ARPU, churn, CAC, payroll, tools.
- P&L. Revenue → COGS → Gross Margin → OpEx → EBITDA.
- Cash flow. When does cash arrive? When does it leave? When do you run out?
Don't get fancy. A clear, tweakable Google Sheet beats a beautiful model nobody updates. Refresh monthly.
