|---|---|
| Input discipline | Use landed costs, fees, tax treatment, timing and realistic volume instead of best-case numbers. |
| Stress test | Run a worse-case version before treating the result as safe. |
| Decision trigger | Only act when the number still works after discounts, delays or repayment pressure. |
| Review signal | Compare the estimate with actual cash flow, not just revenue or headline rate. |
