Build a Marketplace App in 21 Days
Two-sided marketplace with buyer/seller flows, Stripe Connect, and search — shipped at a fixed price.
Why Marketplace App development is hard to get right
Stripe Connect for split payments is complex to configure — most freelancers get the KYC and payout flow wrong
Two-sided marketplaces need distinct UX for buyers and sellers — effectively two products
Trust mechanisms (reviews, ID verification, escrow) are critical for conversion but add complexity
Search and discovery with filters is non-trivial — buyers expect Airbnb-quality search from day one

Frequently asked questions
What's the minimum marketplace MVP?
Seller listing creation, buyer checkout (Stripe Connect), email confirmation, and basic seller payout. No reviews, no messaging, no admin dashboard for v1 — validate the core transaction first.
Do I need Stripe Connect?
Yes, if you're facilitating payments between buyers and sellers and taking a commission. Stripe Connect handles seller KYC, split payments, and 1099 tax forms automatically. Building this yourself is 3–6 months of compliance work.
What type of marketplaces have you built?
Services marketplaces, rental platforms, digital goods marketplaces, B2B supplier platforms, freelance platforms, and course/content marketplaces. The architecture pattern is consistent — the domain-specific details differ.
