Build a Multi-vendor Marketplace Website

Multi-vendor marketplaces like Amazon or Etsy offer complex system design challenges involving seller onboarding, product management, payment splitting, and customer order workflows — a great full-stack project experience.

Allow multiple sellers to onboard, list products, and manage their store dashboards. Customers can browse across all stores, add to cart, purchase items, and track orders.

Sellers register and manage their products through a vendor dashboard. Customers browse all available products across sellers, add items to their cart, make payments securely, and track order statuses. Sellers fulfill orders individually.

• Sellers create accounts, build store profiles, and list products.
• Customers shop across multiple stores, add products to a universal cart.
• During checkout, orders are split based on vendors and processed separately.
• Vendors manage their own orders and update shipping statuses.
• Optional: Add commission fees deducted by platform from each vendor sale.
