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
- Microservices - Separate services for orders, inventory, payments, and notifications
- Event-Driven - Real-time updates using message queues
- 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
