Marketplaces are technically the hardest business model to build. The billing, the trust, and the two-sided product have no shortcuts.
Two-sided marketplaces require specific technical infrastructure: Stripe Connect for multi-party payment flows, trust and verification systems for both sides, and the search and matching experience that makes the marketplace work at low liquidity. We've built them.
Building a marketplace application that needs Stripe Connect for seller payouts, two-sided user management, and the search and matching that makes a marketplace function
Marketplaces are technically complex because they have two user types with opposing motivations, a three-way payment flow (buyer → platform → seller), and a trust problem that doesn't exist in simpler applications.
The payment flow. When a buyer pays in a marketplace, the money doesn't just go to the seller — the platform takes a fee, and the seller gets the remainder. Implementing this with Stripe requires Stripe Connect, which has its own account type decisions (Standard vs. Express vs. Custom), onboarding flow requirements, and payout timing considerations. Implementing marketplace payments without Stripe Connect is possible but results in legal and operational problems (the platform holding seller funds may require financial licensing).
The trust problem. Buyers don't know if sellers are legitimate. Sellers don't know if buyers will pay or show up. The marketplace software needs to address this: identity verification during seller onboarding, review systems after transactions, dispute resolution workflows, and the buyer protection policies that make buyers willing to transact.
The two-sided supply-demand problem. At launch, a marketplace has no sellers and no buyers. The early-stage marketplace needs to optimize for supply first (sellers are the harder side to acquire), then use supply to attract buyers. The search and discovery experience matters most when the selection is thin.

Why Fixed-Price Matters Here
Marketplace scope is defined by the transaction model, the user types, and the trust and verification requirements. Fixed price after scope definition.

Questions, answered.
Express is the right choice for most marketplaces: faster onboarding than Standard (Stripe hosts the onboarding flow), more control than Standard over the user experience, and less engineering effort than Custom. Custom is appropriate only when full control over the payment experience is required and the engineering investment is justified.
The supply-first strategy: launch with a curated set of sellers onboarded directly before the marketplace is public. Use that supply to attract initial buyers via targeted marketing. The software supports manual seller invitation and curation workflows in the admin panel.
Service marketplace with Stripe Connect: from $45k. Physical goods marketplace with inventory management: from $55k. Fixed-price.
