What is a marketplace platform?
A marketplace platform is a website where multiple independent sellers list their products or services, and the platform operator earns a commission on every transaction. Unlike a classic online store (one seller), a marketplace manages vendor accounts, a shared catalog, payments split between the platform and its sellers, and separate invoicing for each party.
Short answer — how you launch a marketplace with 4buildsite
- Pick your monetization model: per-transaction commission, vendor subscriptions, or both.
- Onboard your vendors — each gets an account, their own product pages and KYC verification through Stripe Connect.
- Launch: every order splits automatically (the vendor's share + your commission), and invoices are issued for each party, depending on your country and set-up.
What types of marketplace you can build
The same foundation — vendor accounts, catalog, split payments, invoicing — adapted to your business model.
Product marketplace (B2C)
Multiple sellers list products in a shared catalog, with a single cart and unified checkout.
e.g. a niche Etsy/Amazon-style local platformServices marketplace
Providers with profiles, calendars and bookings — the client pays on the platform, the provider gets paid minus commission.
e.g. tradespeople, courses, consulting, beautyB2B / wholesale marketplace
Catalogs with per-client negotiated prices, bulk orders and B2B invoicing, depending on your country and set-up.
e.g. distributors → local shopsRentals and bookings
Listings with calendar availability, deposits and staged payments — equipment, venues, vehicles.
e.g. equipment or event-space rentalsHow you launch the marketplace (3 steps)
Define the model
Choose the marketplace type (products, services, B2B, rentals) and the monetization model: per-transaction commission, vendor subscription or both. Configure categories and listing rules.
Onboard the vendors
Vendors create accounts, complete their profile and company details, and pass KYC verification through Stripe Connect. Each gets their own vendor pages and dashboard.
Launch and earn
Publish the platform in one click — hosting, SSL and CDN included. Every order splits automatically between vendor and platform, and invoices are issued for each party, depending on your country and set-up.
What the marketplace platform includes
The features that separate a marketplace from a simple online store — included, not “on request”.
Vendor onboarding with KYC
Each vendor gets their own account, fills in company details and passes KYC verification through Stripe Connect — legally required for split payments.
Configurable commissions
A global percentage, per category or per vendor. You can combine commission with monthly vendor subscriptions.
Automatic split payments
On every order the money splits automatically: the vendor's share goes to their Stripe account, your commission stays with you. No manual settlements.
Invoicing for each party, depending on your country and set-up
The vendor invoices the customer, and the platform can invoice its commission to the vendor — invoicing depends on your country and set-up.
Operator dashboard
See GMV, commissions, active vendors, orders and disputes in one panel. Vendors get their own dashboard with their orders and payouts.
SEO + GEO per listing
Every product and vendor page ships JSON-LD (Product, Offer, AggregateRating) and an extractable structure.

4buildsite advantages for marketplaces
- Native split payments through Stripe Connect — the vendor's share and your commission separate automatically on every order.
- Invoicing for both parties (vendor → customer, platform → vendor) depends on your country and set-up.
- Vendor onboarding with KYC included — you don't build the verification flow payment processors require.
- GEO-ready product and vendor pages (JSON-LD, extractable structure).
- Hosting, SSL and CDN included — no separate infrastructure to run for a platform with variable traffic.
- Connected to the 4b2b ecosystem: you use the other 4b2b products with the same account, and invoicing is available through 4invoices.net.
Cons
We are transparent — here is where 4buildsite is not yet the best marketplace choice:
- Not an enterprise solution like Mirakl for retailers with thousands of vendors and a dedicated SLA.
- Split payments run through Stripe Connect — a different split-payment processor means custom development.
- Very specific marketplace logic (auctions, algorithmic matching, custom escrow) needs the team, not just configuration.
- Invoicing depends on your country and set-up. Confirm the setup for your market before launch.
Short verdict
Choose 4buildsite for a marketplace when you want to launch a multi-vendor platform quickly, with split payments and invoicing (depending on your country and set-up), without building the infrastructure from scratch and without enterprise-level costs. If you already operate at the scale of thousands of vendors with contractual SLA requirements, an enterprise platform like Mirakl remains the right pick.

Frequently asked questions about marketplaces
What is the difference between an online store and a marketplace?
An online store has a single seller: you. A marketplace has multiple independent sellers listing their products or services, while you — the operator — earn a commission on every transaction. Technically, the big differences are payments (money splits between vendor and platform) and invoicing (each party invoices separately).
How is the money split between the platform and the vendors?
Through Stripe Connect: on every order, the vendor's share goes automatically to their Stripe account and the platform's commission stays with you. No manual settlements, and you never hold vendors' money in your own account — which also keeps you clear of payment-intermediary obligations.
Do I need a license to operate a marketplace?
When payments are processed through Stripe Connect, Stripe is the licensed payment institution, not you — your platform never touches the vendors' money. Your fiscal obligations remain: invoicing your commission to vendors and, in the EU, DAC7 reporting of vendor earnings on your platform.
How do I invoice my commission to vendors?
The platform can invoice its commission to each vendor, monthly or per transaction. Invoicing depends on your country and set-up.
How much does it cost to launch a marketplace with 4buildsite?
Less than a custom build (tens of thousands of euros) and without Mirakl-level enterprise costs. You pay a monthly platform subscription plus Stripe processing fees; commissions and the monetization model are yours to set. See the pricing page for current plans.
Can I turn my existing online store into a marketplace?
Yes. If the store already runs on 4buildsite, you enable the multi-vendor module: vendor accounts, KYC onboarding and split payments, keeping your existing catalog and customers. If it runs elsewhere, we migrate the catalog first and then enable the marketplace layer.
