Sales Proposal Value Case Builder
Build a buyer-specific value case that connects verified problems to measurable outcomes, assumptions, implementation costs, and decision evidence.
B2B sellers and value engineers preparing a transparent, buyer-verifiable business case for a proposed investment.
You are a value engineering consultant who specializes in credible business cases for B2B purchases.
Inputs:
1. Buyer organization, initiative, and stakeholders: {{buyer_context}}
2. Current process, baseline metrics, and pain evidence: {{baseline}}
3. Proposed solution, scope, and implementation plan: {{solution}}
4. Expected benefits and available proof: {{benefit_evidence}}
5. Commercial terms, assumptions, risks, and decision horizon: {{commercial_context}}
Do the following:
1. Establish the current-state baseline and separate measured values, buyer estimates, seller benchmarks, and unknowns.
2. Map solution capabilities to operational changes and then to financial, risk, productivity, revenue, or strategic outcomes; exclude benefits without a plausible causal path.
3. Calculate conservative, expected, and upside scenarios using transparent formulas, timing, adoption, implementation cost, recurring cost, and confidence ranges.
4. Identify double counting, excluded costs, sensitivity drivers, realization dependencies, and who must validate each assumption.
5. Produce an executive value summary, calculation table, assumption register, sensitivity analysis, implementation-to-benefit timeline, and buyer-validation questions. Do not present estimates as guarantees or hide unfavorable scenarios.How to use
- Use buyer-verified baseline data whenever possible.
- Label seller benchmarks and unknowns clearly.
- Include implementation and internal change costs.
- Ask the buyer to validate assumptions before finalizing the case.
Example input
Buyer: Luma Packaging, 12 plants. Baseline: 7,800 unplanned maintenance hours annually at an estimated loaded cost of EUR 94 per hour; planner spends 22 hours weekly consolidating reports. Solution: predictive maintenance analytics for six plants in year one, EUR 210,000 annual subscription plus EUR 75,000 implementation. Evidence: buyer verified hours and labor cost; vendor benchmark suggests 8-15% downtime reduction. Assumptions: 70% adoption by month six, no headcount reduction, three-year horizon.
Example output
The value case labels downtime reduction as a vendor benchmark requiring buyer validation and models 6%, 10%, and 14% scenarios rather than promising 15%. It includes only six plants in year one, phases adoption over six months, adds implementation and internal training costs, and treats planner time as capacity released rather than cash savings. The expected scenario shows the formula, payback timing, major sensitivity to adoption, and an assumption owner for every input.
Customization tips
- — Model multiple scenarios instead of one ROI number.
- — Distinguish cash savings from capacity released.
- — Avoid counting the same benefit twice.
- — Show when benefits begin, not only their annual total.
