Let's CONSIDER THREE organizations such as A the service provider, B the service receiver and, C works as a vendor which provides the services to service providers. In this situation when A receives a purchase order from B it either manufactures it or purchases it. If the option of procurement is chosen, then after RECEIVING the purchase order from B, A creates a SALES order for it. Also it creates a purchase order for C to arrange the goods. C prepares the product and sends to A which delivers it to B, that is the ultimate buyer. This process is called the trading process.
