The narrative of Order processing

When an order comes in, the order-processing clerk checks the customers credit file to confirm credit approval and ensure that the amount falls within the credit limit. If either of these conditions is not met, the order is sent to the credit department. If an order meets both conditions, the order-processing clerk enters it into the system on a standard order form. The data on the form is used to update the companys customer file (in which the name, address, and other data are stored), and the form is placed in the companys open order file. When the credit department receives a rejected order, the credit clerk determines why the order has been rejected. If the credit limit has been exceeded, the customer is notified that the merchandise will be shipped as soon as Dub 5 receives payment. If the customer has not been approved for credit, a credit application is sent to the customer along with a notification that the order will be shipped as soon as credit approval is granted. Before preparing a packing slip, the system checks the inventory records to determine whether the company has the products ordered on hand. If the items are in stock, a packing slip is prepared and sent to the warehouse. Once notification of shipped goods has been received from the warehouse, a customer invoice is prepared. A copy is filed by the order-processing department, another is sent to the customer, and another is sent to the accounting department so that accounts receivables can be updated. A note is placed in the customer file indicating that the invoice has been sent.
