Draw a business process model for the given case narrative

When a customer receives the quote, they will respond in one of four ways: 1. Accept the quote by signing it and returning it to the Sales Office, either via the post or in person. Accepting a quote also requires the payment of a 30% deposit before work can proceed (see below for more details). 2. Request a variation to the quote by writing the details of the required variations on the quote and/or plans, and returning the document(s) to the Sales Office, either via the post or in person. 3. Reject the quote by ticking a box on the quote and returning it to the Sales Office, either via the post or in person. 4. Do nothing (also effectively a rejection of the quote). In the case of (1), a Sales Assistant will photocopy and file the accepted quote. Then, they will raise a purchase order (PO) detailing the agreed price, work to be done and other formalities, using information from the quote, and send it to the customer for signature. If the customer does not return the signed PO within one month, the sales assistant will place a cancellation note on the customer's file, and the case completes at this point. Otherwise, when the signed PO is received from the customer, the Sales Assistant will send it to the Finance Office to await the payment of the deposit. If payment of the deposit is not received within two weeks of the PO acceptance date, a Finance Officer will return the PO to the Sales Office, with a non- payment advice attached. A Sales Assistant will place the non-payment advice on file, and the case completes at this point. Otherwise, when payment is received from the customer, the payment is processed by a Finance Officer, who will then produce a receipt in triplicate: one copy is sent to the customer via mail, one copy is attached to the accepted PO and returned to the Sales Office, and one copy is placed on file in the Finance Office. On receiving their copy of the receipt, a Sales Assistant will place it on the customer's file
