How is commission calculated?

When an order is placed, the system calculates: gross = item price × quantity; commission = gross × commission_rate; net = gross − commission. These values are recorded on the vendor_orders record and aggregated in the periodic payout.

Can vendors customize their storefront?

Yes. Each vendor has a branded storefront URL (marketplace.com/store/vendor-name) with their logo, banner, and bio. They can organize products into collections and highlight featured items. Customization options vary by vendor subscription tier.

How are buyer disputes handled?

Buyers can open a dispute on any unfulfilled or misrepresented order. Both buyer and vendor submit evidence in the dispute portal. A platform moderator reviews and issues a ruling - refund to buyer, release to vendor, or partial resolution.

The Challenge

Why building a Multi-Vendor Marketplace from scratch is hard

Building a Multi-Vendor E-commerce Marketplace from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing multi-vendor marketplace-specific business logic, integrations, and role-based access rules.

Architecture

How it's built

The generated Multi-Vendor Marketplace follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for multi-vendor marketplace workflows

NestJS REST API with dedicated multi-vendor marketplace modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all multi-vendor marketplace entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live multi-vendor marketplace status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

Database

PostgreSQL schema designed for Multi-Vendor Marketplace

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

vendors (id, user_id, store_name, slug, description, logo_url, commission_rate, bank_account jsonb, status, workspace_id)
vendor_products (id, vendor_id, name, sku, price, quantity, category, images jsonb, status)
vendor_orders (id, order_id, vendor_id, items jsonb, subtotal, commission, net, status, payout_id)
payouts (id, vendor_id, period, total_orders, gross, commission, net, status, paid_at)

FAQ

Common questions about building a Multi-Vendor Marketplace

Each vendor connects their bank account via Stripe Connect. When an order is placed, the platform collects the full payment. After the order is fulfilled and any dispute window passes, Stripe transfers the vendor's net amount (sale price minus commission) to their connected account.
