A complete, deployable proposal automation platform built for agencies and freelancers. Pre-revenue. Priced as a code and infrastructure asset — not on earnings multiples. Comparable build from scratch: $35,000–$50,000 and 4–6 months of development. You can own and deploy this today for $9,000. What You're Buying A fully functional AI proposal platform where users answer six questions about a project and receive a complete, client-ready proposal — with scope of work, itemised pricing, timeline, executive summary, and terms. Proposals are delivered via a branded client portal with built-in e-signature, audit trail, and PDF export. No third-party tools like DocuSign required. This is not an AI wrapper. It is a structured 12-stage generation pipeline purpose-built for professional service businesses. Tech Stack Frontend: Next.js, React, TypeScript, Tailwind CSS, Radix UI, Framer Motion Backend: Supabase AI: OpenRouter (12-stage pipeline) Payments: Stripe (Free / Pro $29 / Agency $79 — tiers already configured) Editor: TipTap + React-PDF Deployment: Vercel (single-command deploy, zero backend servers) Email: Nodemailer SMTP Three Clear Business Models for a New Owner A vertical SaaS operator can niche this down to a specific industry — construction, creative agencies, SEO firms — where proposal tooling commands higher retention and LTV than general tools. A agency owner can deploy this internally to replace their existing proposal workflow, then white-label and resell it to peers as a packaged sales system. A SaaS operator can activate the existing Stripe tiers immediately and focus entirely on distribution, with no additional development needed before charging customers. What's Included Full source code and all intellectual property Premium domain (proposalbuildr.com) 40+ industry-specific templates with market-rate pricing data Technical documentation and deployment guide 7 days of post-sale transition support from the builder
