How to Build a Multi-Vendor eCommerce Marketplace (Shop + Sellers)
How to Build a Multi-Vendor eCommerce Marketplace (Shop + Sellers)
A multi-vendor eCommerce marketplace combines your own storefront with third-party sellers — like Amazon selling its own products alongside marketplace sellers. This hybrid model maximizes catalog breadth and revenue.
Architecture: Your Shop + Sellers
Two Revenue Streams
- Your own products — Full margin, you handle fulfillment
- Seller products — Commission on each sale, sellers handle fulfillment
User Roles
| Role | Capabilities |
|---|---|
| Buyer | Browse all products, purchase from anyone |
| Seller | List products, manage orders, receive payouts |
| Platform (you) | Sell your own products + earn commission on seller sales |
| Admin | Manage everything |
Key Differences from Pure Marketplace
| Feature | Pure Marketplace | Hybrid (Shop + Sellers) |
|---|---|---|
| Your own products | No | Yes |
| Seller products | Yes | Yes |
| Payment flow for your products | N/A | Direct to your Stripe account |
| Payment flow for seller products | Stripe Connect split | Stripe Connect split |
| Fulfillment | Sellers only | You + Sellers |
| Product quality control | Moderate | High (your products set the standard) |
Implementation Approach
Product Ownership
Every product has an ownerId field:
- If
ownerIdmatches the platform admin → your product (no commission split) - If
ownerIdmatches a seller → seller's product (commission deducted)
Checkout Logic
When processing checkout:
- Separate cart items by owner (platform vs. each seller)
- Platform products → charge goes directly to your Stripe account
- Seller products → create destination charges with application fees
- All items in one cart, one checkout experience for the buyer
Unified Catalog
Buyers don't see ownership distinctions. All products appear in the same catalog, same search results, same category pages. The only visible difference: your products show "Sold by [Your Brand]" and seller products show "Sold by [Seller Name]."
