What it does

Generate professional sales proposals that persuade, differentiate, and close deals

Best for

Founders and sales leaders closing mid-market deals ($10K-$100K+) who need a professional proposal that leads with client pain, not service features, and anchors price to measurable ROI.

Inputs

· Client company name, URL, and industry
· 3-5 specific pain points the proposal solves
· Proposed solution/service (specific deliverables)
· Engagement model (retainer/project/performance-based/hybrid)
· Budget range or three-tier pricing options
· Timeline (start date, milestones, duration)
· 2-3 relevant case studies with measurable results
· Prior analysis files (PROSPECT-ANALYSIS.md, LEAD-QUALIFICATION.md, etc., optional)

Outputs

· CLIENT-PROPOSAL.md (or PDF) with 11 sections:
· Executive Summary (their problem in 2 sentences)
· Situation Analysis (what they're experiencing, why it matters)
· Proposed Solution (what you'll do, specific deliverables, timeline)
· Why [Your Company] (differentiators, proof points, team)
· Investment and ROI (price anchored to business outcomes, not just hours)
· Case Studies (2-3 similar clients with results)
· Implementation Timeline (phased approach with milestones)
· Success Metrics (how we'll measure success together)
· Terms and Conditions (payment schedule, scope, approval)
· Next Steps (clear decision point and deadline)

Preconditions

· All required inputs must be provided (no generic proposal without client context)
· 3+ pain points specific to this client (not generic vertical pain points)
· Proof points or case studies exist (to anchor ROI claims)

Failure modes

· Proposal under 15 pages suggests missing sections → looks thin
· Over 20 pages → loses decision-maker attention
· Generic pain points → client feels not understood
· Price without ROI anchor → appears expensive
· No clear next step → proposal sits unsigned

Trust signals

· 11-section structure (problem → situation → solution → why-you → ROI → cases → timeline → metrics → terms → next-steps)
· Writing principle: lead with THEIR problems, not your services
· ROI anchor example: "$10K/month generates $50K revenue" vs "$10K/month"
· Auto-incorporation of prior analysis files (PROSPECT-ANALYSIS, LEAD-QUALIFICATION, etc.)
· Proposal writing principles enforced (15 pages max, client's own language, specific case studies)
