Stripe Connect for a marketplace: what you need to know before coding

A marketplace is not an e-commerce site with multiple sellers. The core issue is split payments— collecting from a buyer, deducting a commission, and paying out the rest to the seller, all while staying compliant. Stripe Connect is built for this.

What Stripe Connect handles for you

Connect adds to Stripe the concept of seller accounts and split payments (split). In practice:

• Each seller has a connected, onboarded, and verified account.
• With every transaction, the platform deducts its commission and pays out the balance to the right seller.
• Payouts, statements, and dispute management are all handled.

This is the foundation of a marketplace that meets compliance from day one, rather than patching together manual transfers.

The topic that raises concerns: KYC and compliance

As soon as you handle other people’s money, you enter a regulated framework: identity verification (KYC), anti-money laundering (AML), audit logs. Stripe Identity covers KYC, and Connect integrates part of the compliance. But this isn’t something you improvise—it’s designed from the start, not after the first audit.

This is precisely where marketplaces most often fail—and one of the first things we overhaul when we take over a blocked marketplace.

Stripe or MangoPay?

Stripe isn’t the only option. MangoPay, a European marketplace specialist, offers the segregation of funds (wallets) and an EU regulatory approach that may better suit certain setups.

• Stripe Connect: best developer and user experience, global coverage, full ecosystem (Billing, Identity). Our default choice.
• MangoPay : European marketplace, need for fund segregation, specific EU regulatory constraints.

The decision is made during scoping, based on your geography and business model—never imposed by default.

The technical pitfall: webhooks

Behind the scenes, everything relies on the webhooks Stripe is the one that signals whether a payment succeeded, failed, or if a dispute was opened. Poorly managed, they can lead to lost payments or double-counting. We handle them in a way thatidempotent, with follow-ups and reconciliation — so no transaction slips through the cracks.

Before coding

The business model (commission? subscription? both?), geography, and required compliance level: all of this must be defined before writing the first line of code. That’s what we do on our projects forcustom marketplace, with a fully tested Stripe integration — see our page for details Stripe Agency.
