One checkout. Many vendors. Payouts split automatically.
Custom marketplace platforms with automated commission splitting, vendor onboarding and verification, and dispute resolution — built so every payment settles correctly without you touching a spreadsheet.
Built for platforms where money touches more than two parties
A marketplace is fundamentally different from a store — every order has to route money, notifications, and fulfillment to the right vendor, correctly, every single time.
Six systems every marketplace needs
Vendor onboarding & KYC
An application flow with identity verification handled through the payment platform, plus an admin approval step before a vendor can list anything.
Commission & payout engine
Payments split automatically at checkout — flat, category-based, or volume-tiered commission rules, with payouts routed directly to each vendor's connected account.
Per-vendor storefronts
Each vendor manages their own listings, inventory, and order queue, scoped so they only ever see their own data.
Order routing & fulfillment tracking
A single order that spans multiple vendors gets split into vendor-specific sub-orders automatically, each tracked to fulfillment independently.
Ratings, reviews & disputes
Buyer reviews scoped per vendor, plus a structured dispute flow tied to the specific order rather than a generic support inbox.
Admin oversight dashboard
Platform-wide visibility into GMV, commission revenue, vendor performance, and open disputes, in one role-scoped view.
The payout architecture in plain terms
| Payment split | Handled at the transaction level via Stripe Connect (or an equivalent marketplace payment platform) — the platform never manually calculates or wires a payout. |
|---|---|
| Vendor identity verification | Required by the payment platform before payouts can be enabled, satisfying KYC obligations without the marketplace owner handling sensitive ID documents directly. |
| Commission logic | Stored as a configurable rule set (flat, per-category, or tiered by volume) rather than hardcoded, so rates can change without a code deployment. |
| Data isolation | Every API query is scoped to the authenticated vendor's own records — the same permission-enforcement pattern used in the admin dashboard service, applied per vendor here. |
Three starting points, and when each fits
Single-vendor store
The right build if there's only one seller. A multi-vendor marketplace is a materially different system, not an upgrade of a single store.
Marketplace SaaS (Sharetribe, etc.)
Fast to launch and reasonable for testing the model. Commission logic, branding, and vendor workflows are constrained by the platform.
Custom-built marketplace
Full control over commission rules, vendor experience, and branding, with no per-transaction platform fee beyond payment processing.
Five stages, from commission model to launch
Design the vendor & commission model
Vendor roles, commission structure, and payout rules defined and agreed before any schema is built.
Build payment architecture
Stripe Connect (or equivalent) integration, split-payment logic, and vendor onboarding/KYC flow.
Build storefronts & order flow
Weekly demos against a working marketplace with real vendor and order data.
Dispute & admin tooling
Dispute workflow and the admin oversight dashboard, tested against real order scenarios.
Launch & vendor rollout
Staged vendor onboarding, monitoring on real transactions, and an optional maintenance plan.
Common questions
How much does multi-vendor marketplace development cost?
A focused marketplace — vendor storefronts, one commission model, and Stripe Connect payouts — typically starts in the mid five figures. Multi-currency support, complex tiered commissions, dispute workflows, or a mobile app increase the scope. Vendor roles, payout complexity, and logistics integrations move the price most.
How are vendor payouts actually handled?
Through a payment platform built for marketplaces, most commonly Stripe Connect. When a customer pays, the payment splits automatically at the transaction level — the platform's commission is retained and the remainder routes directly to the vendor's connected account.
Can commission rates differ by vendor or product category?
Yes. Commission logic is built as a configurable rule set — flat, category-based, or tiered by sales volume — rather than hardcoded, so the model can be adjusted as the marketplace grows without a code change.
How is vendor onboarding and verification handled?
New vendors go through an application and KYC step handled by the payment platform's identity verification, required before they can receive payouts, alongside a platform-side review where the marketplace owner approves vendors before they can list products.
How are disputes between buyers and vendors resolved?
Through a structured flow: the buyer or vendor opens a case tied to the specific order, an admin dashboard surfaces it for review, and resolution actions (partial refund, full refund, or releasing the payout) are logged against the order.
How long does it take to build a multi-vendor marketplace?
A focused marketplace MVP — vendor storefronts, one commission model, and core checkout — typically takes ten to fourteen weeks. Dispute workflows, advanced search, and logistics integrations extend that timeline, since each is effectively its own sub-system.
