Return Merchandise Authorization, or RMA, refers to the documented and authorized process by which a customer or retailer requests and obtains approval to return a product to the manufacturer or supplier. It is a crucial element of efficient inventory management, allowing for the organized tracking, inspection, and resolution of returned goods, often involving the replacement, repair, or refund of the product. RMA helps streamline reverse logistics, enhance customer satisfaction, and manage product quality and warranty issues within the supply chain.
