The Prompt

prompt.txt
Build a revenue forecast model for the following business. Include:
1. Forecasting methodology: bottom-up from pipeline or top-down from market
2. Key input assumptions with confidence levels
3. Three scenarios: bear / base / bull case
4. Monthly forecast for next 12 months
5. Seasonality adjustments if applicable
6. Sensitivity analysis: which assumptions matter most
7. Forecast accuracy metric: how to track forecast vs. actuals

Output as tables I can implement in a spreadsheet.

Business context:
- Revenue model: [SUBSCRIPTION / TRANSACTIONAL / SERVICES]
- Current run rate: [CURRENT ARR OR MONTHLY REVENUE]
- Historical growth: [PAST GROWTH RATE IF KNOWN]
- Pipeline: [SALES PIPELINE VALUE IF B2B]
- Key uncertainties: [WHAT COULD CHANGE THE FORECAST MOST]

Example Output

12-month forecast: base case $1.2M ARR (48% growth) with assumptions of 12% monthly new ARR, 3% monthly churn, 110% net revenue retention. Bear case: 8% monthly new ARR + 5% churn = $840K ARR. Bull: 18% new ARR + 2% churn = $1.8M. Tornado chart shows churn rate is 2x more sensitive than growth rate.
