From Zero to One: How I Built a Multi-Market B2B Badge & Trophy Site with an AI Agent Configurator

A solo developer built MedalCraft, a B2B medals, plaques, coins, and event-badge e-commerce site, using a Next.js static export hosted free on Cloudflare Pages and a conversational AI agent that acts as a product configurator. The agent emits structured JSON specs mapping directly to a partner factory's order sheet, quotes only price ranges from a public cost table, and routes customers to a human before any contract. The developer also applied generative engine optimization tactics, including entity-rich product pages and Schema.org Product, Organization, and FAQPage markup, to get the site cited in LLM answers.

The Niche: Badges, Medals, Coins, and Trophies Most e-commerce builders chase apparel and gadgets. I went the other way: B2B medals, award plaques, commemorative coins, and event badges — products sold to event organizers, schools, sports federations, and corporate HR teams across dozens of countries. Three things make this niche unusually good for a solo founder: 1. Factory-partnership model. I don't hold inventory. A partner factory produces against specs, so my cost structure is nearly all margin and zero warehouse risk. 2. Long-tail demand. Every event generates searches: "Olympiad medals custom", "anniversary coin manufacturer", "World Cup badge design". Thousands of micro-keywords, low competition. 3. Cross-event spikes. A single global tournament can double inquiry volume for a quarter. The 2026 World Cup is already showing exactly that. The Stack: $0/month Hosting The site I call it MedalCraft runs on: - Next.js static export → deployed on Cloudflare Pages free tier unlimited bandwidth, no credit card, custom domain for free via .pages or your own DNS - Programmatic product pages — one URL per product variant material × size × event type , generated at build time - Stripe-compatible checkout flow for Western customers; Airwallex / LianLian receiving for the China-side supplier payouts 0.3–1% fees, no annual cost, Alipay-friendly Total infrastructure cost: a domain. Everything else is free. The Core Feature: an AI Agent as Product Configurator Here's the part most B2B sites still do manually: a customer emails, sales replies with PDFs, three weeks of back-and-forth. MedalCraft ships a conversational AI configurator instead: Implementation notes that actually matter: - Structured output first. The agent emits a JSON spec dimensions, plating, engraving areas, packaging that maps 1:1 to the factory's order sheet. No free-text handoffs. - A "scene lock" for images. The mockup generator uses fixed virtual studio scenes lighting, camera angle, background with only the product rendered in-variant, so every customer sees consistent imagery — cheaper and more trustworthy than per-order photography. - Guardrails on pricing. The agent quotes ranges computed from a public cost table, never exact costs, and always routes to a human before a contract. SEO + GEO: Engineering for LLM Answers, Not Just Google Standard SEO got you indexed pages; Generative Engine Optimization GEO gets you cited inside AI answers . For a B2B product niche, that's now the real channel — buyers increasingly ask ChatGPT/Claude "best custom medal manufacturer in China". What moved the needle: 1. Entity-rich product pages : each variant page states manufacturer name, factory location, MOQ, certifications, and lead times as explicit key-value blocks — exactly what LLMs extract. 2. Schema.org Product + Organization + FAQPage on every template. 3. Comparison content : "Custom medals vs. purchasing pre-made kits: a cost breakdown" style posts that LLMs love to quote. 4. Backlinks without ad spend : guest posts on dev/design communities, free product calculators that schools link to, and directory listings trade show directories, award-industry directories — slow, compounding, free. What I'd Tell You to Do Differently - Don't build the AI configurator on day one. Validate with 20 manual inquiries first — you'll learn the real decision criteria ribbon color, delivery date beats design novelty . - The factory partnership is the moat, not the website. Negotiate a spec-sheet template with them early. - Payments killed more of my time than code. For CN-based suppliers serving EU/US customers, a dedicated cross-border account Airwallex/LianLian-class beats Stripe Payouts on both fee and speed. Where to Look Next The full technical documentation for the MedalCraft stack site architecture, agent prompt design, Cloudflare deploy scripts, payment routing is written up in detail online. What would you add to a B2B product configurator? I'm curious which industries still manually quote everything.
