Standardization Model for Return Merchandise Authorization Processes Across Multi-Vendor Supply Chains

Return Merchandise Authorization (RMA) processes are critical components of supply chain operations, especially in multi-vendor environments where product returns must be efficiently managed across diverse stakeholders. However, the absence of standardized procedures often leads to inefficiencies, increased costs, and reduced customer satisfaction. This paper reviews existing RMA practices, highlights the challenges of fragmented return processes, and explores the benefits of adopting a standardized model across multi-vendor supply chains. By examining frameworks for interoperability, information transparency, and performance metrics, the study proposes a structured RMA standardization model that integrates digital technologies such as blockchain, cloud-based platforms, and advanced analytics. The model emphasizes consistency, traceability, and collaboration to enhance operational efficiency, reduce redundancy, and improve customer experience. Findings suggest that standardization not only streamlines returns but also contributes to sustainability goals through optimized reverse logistics and reduced resource wastage. This review provides a foundation for future research and implementation strategies aimed at harmonizing RMA processes in global supply chain ecosystems.
