At Safari Sporting Goods (SSG) the revenue cycle is a partly automated and centralized computerized process that begins when a customer places an order on the checkout page on the companys website. However, before a customer can place an order, the system evaluates if the customer exists. If the customer does not exist, the customer is asked to create an account with SSG. If the customer account exists, the customer is given the opportunity to review the shopping bag information for accuracy. The checkout page displays shipping, payment, and order details. Once the customer verifies the accuracy of the data, the customer clicks the place order button and the customers purchase is processed along with the customers credit card payment. If the credit card authorization fails, the customer order is rejected.

After the customer order is entered into the system, the inventory-check program determines whether the item(s) and the quantity ordered are available for sale. If the items are available, the customer order is added to the open sales order file and is displayed in the customer shopping bag. If the items are not available, customers are notified of the unavailability and are provided with like items to purchase.

Please help me draw a flowchart for this.
