Order In Process refers to a transaction that occurs when a customer places an order for goods or services and the supplier begins to fulfil the order, either through the process of delivering the product or completing the service. This term is often used in business to indicate that a company has begun to act on an order, rather than simply receiving and processing it. It can also apply to cases where payment has been made but the order is still being completed. By tracking orders in process, businesses are able to ensure they are meeting customer expectations while managing their resources effectively.
