Define the vendor journey first
A marketplace works only when vendors can join, add products, receive orders, and understand payouts without confusion.
Before launch, create a clear vendor onboarding flow with profile verification, product approval, commission rules, and support contacts.
- Vendor registration and approval workflow.
- Product listing rules and moderation.
- Commission, settlement, and payout policies.
Keep admin control strong
The marketplace owner needs visibility across vendors, products, orders, refunds, payouts, and customer issues.
Admin dashboards should make it easy to filter vendors, review catalog quality, track orders, and resolve disputes.
Test real order scenarios
Marketplace checkout is more complex than a single seller store because one order may involve multiple vendors.
Test split orders, vendor notifications, inventory updates, shipping status, cancellation rules, refunds, and payout reporting before launch.
