Unified marketplace optimization: Building a scalable tech stack for multi-channel eCommerce

Karuppuchamy, Sureshkumar (2025) Unified marketplace optimization: Building a scalable tech stack for multi-channel eCommerce. World Journal of Advanced Engineering Technology and Sciences, 15 (3). pp. 1039-1050. ISSN 2582-8266

This article introduces Unified Marketplace Optimization (UMO), a structured approach to building integrated technical infrastructure for multi-channel eCommerce operations. As retailers expand across platforms like Amazon, eBay, Walmart, and Shopify, they encounter operational challenges from disparate systems with unique requirements for product listings, inventory management, pricing, and fulfillment. These fragmented processes create inefficiencies that compound with scale. UMO addresses these challenges by centralizing data flows, normalizing marketplace-specific requirements, and automating processes to enable consistent customer experiences across channels. The paper explores foundational components including centralized data architecture with robust product information management, inventory synchronization, and unified order management. It examines API integration strategies that connect marketplace platforms through middleware-based integration, microservices, and API gateways. Additionally, the article discusses dynamic pricing systems for cross-platform optimization, analytics frameworks for actionable insights, and emerging technologies shaping future capabilities. By implementing comprehensive UMO strategies, organizations can reduce manual intervention while maximizing operational efficiency in complex digital marketplace ecosystems.
