Return Merchandise Authorization (RMA) is a process used by retailers and manufacturers to manage product returns. When a customer wants to return an item, they must first request an RMA number, which serves as permission to send the product back. This helps the company track returns and ensures that the returned items are eligible for a refund or exchange. Once the RMA is issued, the customer can return the item, usually within a specified time frame. The RMA process helps streamline returns, making it easier for both the customer and the company to handle issues related to defective or unwanted products.
