What affects the timeline

Supply vs demand onboarding

Each side (buyer and seller) needs its own onboarding flow, dashboard, and notification set. Budget for 2× the single-user app effort.

Payment complexity

Stripe Connect Express is 1–2 weeks of integration. Custom payout schedules, escrow, and dispute resolution add another week each.

Search requirements

Basic SQL search: 1–2 days. Algolia or Elasticsearch with facets: 3–5 days. Geospatial search with map: add 2–3 days.

Trust features

Reviews, ID verification (Stripe Identity), background checks, and insurance integrations each add 3–5 days. Start with reviews — it's the minimum trust signal.

Frequently asked questions

What's the minimum marketplace MVP?

Seller listing creation, buyer browsing and checkout (Stripe), email confirmation, and basic seller payout. No reviews, no messaging, no admin dashboard — validate the core transaction first.

Do I need Stripe Connect for a marketplace?

Yes, if you're facilitating payments between buyers and sellers and taking a commission. Stripe Connect handles the compliance (KYC for sellers), split payments, and payouts automatically. Building this yourself is 3–6 months of compliance work.
