Dev4ager builds two-sided marketplaces with vendor onboarding, listings, search, carts, Stripe Connect split payouts, reviews, and moderation, starting with a focused MVP that proves buyers and sellers will actually transact before you spend on scale.
What we build
A marketplace is two products sharing a database: a storefront buyers trust and a business tool vendors rely on, plus the payment plumbing that keeps money moving correctly between them. We build all three, in that order of difficulty.
- Vendor onboarding, profiles, and self-serve dashboards
- Listings with search, filters, categories, and media
- Cart and checkout with Stripe Connect: platform fees and split payouts automated
- Reviews, ratings, and report/dispute flows that build trust
- Admin: moderation, fee configuration, and marketplace analytics
- Notifications for orders, messages, and payout events
How we build it
- Scope. We define the one category and one transaction loop your MVP must nail; a fixed quote follows.
- Design. Buyer flow first (it earns the money), vendor flow second, admin third.
- Build + review. AI-assisted build; money paths get senior review plus extra test coverage.
- Launch + liquidity. Ship narrow, onboard vendors manually, expand from evidence.
Stack we reach for
Next.js TypeScript PostgreSQL Supabase Stripe Connect Meilisearch Vercel
A great fit if…
- You know both sides of a niche and see the matchmaking gap.
- You're running the marketplace manually today (DMs + spreadsheets) and it's working.
- An existing marketplace is stuck on a no-code stack that can't do payouts properly.
Marketplace FAQs
How do payouts and commissions work?
We build on Stripe Connect: buyers pay once, the platform takes its fee automatically, and vendors receive split payouts on your schedule. Stripe handles vendor KYC and compliance: the scariest part of running a marketplace, solved.
What does a marketplace MVP look like?
One category, one niche or city, manually onboarded vendors, and a friction-free buying flow. The goal is proving liquidity (both sides transacting) before feature sprawl. Budgeting help in our MVP cost guide.
How do you handle trust, like reviews and disputes?
Verified-purchase reviews, seller ratings, report/flag flows, and admin moderation tools from day one. Payment disputes run through Stripe's infrastructure with your policies encoded.
Will the marketplace scale as it grows?
Yes. PostgreSQL with proper indexing, cached search, background jobs for heavy work, and a data architecture with a clear growth path. No rewrite at 10,000 listings.
