Order processing is the series of steps taken to fulfill a customer's purchase. It begins when a customer places an order, which is then confirmed and recorded in the system. The process includes checking product availability, preparing the items for shipment, and generating invoices. Once the order is ready, it is packaged and shipped to the customer. Throughout this process, communication is maintained to keep the customer informed about their order status. Efficient order processing is crucial for customer satisfaction and can involve various systems and technologies, such as inventory management and shipping software.
