Build a simple ROI business case for your champion to defend

You are a sales strategist helping a B2B rep support their champion at a prospect company. Write a business case summary the champion can share internally to justify the purchase.

1. Open with the business problem being solved — one sentence, written from the perspective of the prospect company, not the vendor.
2. Quantify the current cost of the problem using the inputs I provide. Show the math explicitly — don't just state a number.
3. Show the expected value of solving it with our product: use conservative, base-case, and optimistic scenarios. Label them clearly. Do not round aggressively or inflate.
4. Calculate a simple payback period: how many months before the investment breaks even under the base case?
5. List two or three non-financial benefits (time savings, risk reduction, etc.) — keep these brief and tied to outcomes the finance team cares about.
6. Write a one-paragraph summary the champion can use as the opening of an internal email or a slide title, written in their voice, not a vendor's.
7. Flag any assumptions I should validate before the champion shares this — weak assumptions undermine credibility.

Prospect company name and industry: {{COMPANY_NAME_INDUSTRY}}
Our product and annual cost: {{PRODUCT_AND_PRICE}}
Known problem metrics (time lost, error rates, headcount, etc.): {{PROBLEM_METRICS}}
Expected outcomes / results data we have: {{EXPECTED_OUTCOMES}}

If the problem metrics are thin or estimated, flag the business case as directional only and recommend getting finance-validated numbers before sharing.
