PROJECT DESCRIPTION & SCOPE

Overview & Implementation

A full-stack B2B business ecosystem platform designed to connect manufacturers, suppliers, traders, wholesalers, service providers and buyers within a unified digital marketplace. The platform combines business discovery, product marketplace functionality, RFQ and vendor bidding, business listings, government-scheme discovery, business services and partner-led lead generation into one centralized ecosystem. Buyers can discover businesses and products, publish requirements through RFQs, receive vendor bids and select suitable suppliers. Vendors can create business profiles, publish products, discover relevant RFQs and submit bids. Business partners can generate and track leads, while administrators manage users, listings, RFQs, products, leads, services, schemes, support tickets, notifications and platform configuration. The platform was engineered as a scalable multi-role application with role-based access control, authentication, notifications, configurable email infrastructure, file management and administrative workflows.
