A scalable marketplace backend enabling flexible business models through offers and requests, dynamic pricing, multi-vendor coordination, and white-label e-commerce capabilities with real-time delivery tracking and communication.
Tradelane powers modern marketplaces with a dual-model approach: traditional product catalogs alongside offer/request matching for negotiation-driven commerce. Sellers list offers, customers browse or post specific requests, and the system facilitates intelligent matching. The platform handles complex pricing scenarios, multi-warehouse inventory, real-time delivery tracking, and direct customer-driver communication - all designed for everything from boutique shops to large multi-vendor ecosystems.
- Go 1.20+
- PostgreSQL
- WebSockets for real-time messaging
- Firebase Cloud Messaging for push notifications
- GPS/mapping APIs for delivery tracking
- JWT authentication
- Cloud file storage
Tradelane supports both catalog browsing and offer/request matching. Customers can search products or post specific needs (e.g., "bulk cotton suppliers"), while sellers publish offers. The system matches compatible offers with requests, enabling both self-service e-commerce and negotiation-based transactions.
Handle complex pricing through warehouse-specific rates, multi-currency support, and unit-based pricing (kg, items, liters, etc.). Discounts and promotions operate with granular rules - time-based offers, category-specific deals, customer loyalty programs, and commission calculations. The financial layer supports subscription models, marketplace commissions, and custom revenue streams.
