Return Merchandise Authorization (RMA) is a system that facilitates the return of products for refunds or exchanges, benefiting both buyers and sellers by streamlining the return process. The implementation of RMA in e-commerce stores enhances customer satisfaction, builds trust, and minimizes inquiries related to returns, ultimately driving sales. Without an RMA system, stores face challenges like unhappy customers and diminished trust, emphasizing the importance of having a robust return management tool.
