Multi-Vendor Aggregation Platform

SELLHUB Multi-Vendor Aggregation Platform SellHub is a multi-vendor aggregation platform designed to solve a fundamental constraint in marketplace integrations: the inability of Target Marketplace's API to connect with more than one seller at a time. By introducing a centralised middleware layer, SellHub allows up to 100 independent electronics vendors to list, manage, and fulfil products through a single authenticated endpoint — all without any modification to the Target Marketplace platform. The platform operates as a transparent intermediary. To Target Marketplace, it is a single, trusted seller. To each vendor, it is a full-featured seller portal with catalog access, competitive pricing intelligence, order management, logistics coordination, and financial reporting. Problem Target Marketplace supports only one API-connected seller. 100 independent electronics vendors need to list their products simultaneously on the platform. Solution A central aggregation layer presents itself as the sole seller to Target Marketplace, while routing product listings, orders, and reporting across all 100 vendors through isolated Seller Central dashboards. Key Mechanic When multiple vendors list the same product, only the lowest-priced active offer is relayed to Target Marketplace. All offers remain stored internally, enabling automatic price-queue management. 1.1 Business Objectives • Enable 100 electronics vendors to sell on Target Marketplace without platform modification • Maintain a single, compliant Target Marketplace API integration • Provide a competitive, self-service vendor experience comparable to established marketplace seller portals • Give platform administrators full visibility across all vendor activity, orders, and financials • Automate best-price selection and order routing with zero manual intervention 1.2 Scope • Vendor onboarding and Seller Central dashboards (100+ vendors) • Master product catalog shared between Central Platform and Target Marketplace • Offer Engine with Offer ID generation and best-price relay logic • Order routing from Target Marketplace through to individual vendors • Commission calculation engine (Target Marketplace fees + platform margin) • Logistics management and shipment tracking • Performance monitoring: ODR, OOS rate, fill rate, seller health • Reporting suite: sellout, financial, performance reports • Admin master dashboard with consolidated cross-vendor view
