Multi-Vendor E-commerce Platform

A comprehensive marketplace solution that transformed how vendors sell and customers shop online.

The Challenge

Our client, a growing retail company, needed a platform that could:

  • Support hundreds of vendors with individual storefronts
  • Handle thousands of products with real-time inventory sync
  • Process millions of transactions securely
  • Provide analytics and reporting for vendors and admins

Traditional e-commerce platforms couldn't meet their scalability requirements, and building from scratch seemed daunting.

Our Approach

We designed a microservices-based architecture that could scale horizontally as the platform grew.

Architecture Decisions

  1. Microservices - Separate services for orders, inventory, payments, and notifications
  2. Event-Driven - Real-time updates using message queues
  3. Multi-Tenant - Isolated vendor data with shared infrastructure

The Solution

Vendor Management System

  • Self-service vendor onboarding
  • Customizable storefront themes
  • Inventory management dashboard
  • Order fulfillment workflows

Customer Experience

  • Unified shopping cart across vendors
  • Intelligent search with filters
  • Real-time order tracking
  • Review and rating system

Admin Console

  • Vendor approval workflows
  • Commission management
  • Platform-wide analytics
  • Dispute resolution tools
