Build a global B2B marketplace platform similar to Tradewheel (https://www.tradewheel.com/), designed to connect buyers and suppliers across multiple industries with a strong focus on lead generation, supplier discovery, and wholesale trade. The system should support two main user roles (buyers and suppliers), where suppliers create detailed company profiles and upload product listings (including images, specifications, MOQ, pricing ranges, and categories), while buyers can search, filter, and browse these listings using advanced filters (category, country, price, supplier type). The platform must include a buying leads (RFQ) module, where buyers post sourcing requests with details such as product specifications, quantity, target price, and preferred supplier location, and suppliers can search, view, and respond to these leads. Core features should include: • User dashboards for buyers and suppliers (manage listings, leads, inquiries) • Product catalog system with categories, search, and SEO-friendly pages • Supplier directory with verified profiles and ratings • Messaging/inquiry system for direct communication • Lead generation engine (RFQs + supplier responses) • Membership/subscription system with free and premium tiers (premium users get more visibility, leads, and inquiries) The platform should also include admin moderation tools (approve suppliers, verify users, manage listings), and optional value-added services such as SEO promotion, featured listings, and dedicated account management to support users and improve conversions. From a UX perspective, the system should be designed as a search-first platform, with a homepage featuring product categories, featured suppliers, and latest buying leads, ensuring fast navigation, high discoverability, and global scalability across multiple countries and industries. Overall, the platform functions as a hybrid of marketplace + trade directory + lead generation system, focused more on connecting businesses and generating inquiries than handling direct transactions.
