The ordering process currently begins when the Sales staff passes on an enquiry from a customer to the Order department (Order Entry System). The Orders department prepare a quotation using a price file and returns a quotation to Sales. A record of the quoted price is held in the quotation file. The quotation is sent to the customer.
