Lakers Athletics is an online store that sells athletic gear for LA Lakers’ fans. Lakers Athletics uses the Internet to take customers orders and deliver the goods. Lakers Athletics operates in Pomona and provides delivery to precertified customers.

Lakers Athletics uses a website to post the merchandise they offer. Customers can view the website to see the catalog of inventory items that are available. The sales process is triggered by a customer accessing Lakers Athletics’ inventory catalog and deciding what and if to order. If the customer sees an item they would like to order, they post a customer order within Lakers Athletics’ sales database.

Periodically, throughout the day, Lakers Athletics’ sales manager accesses the sales database and reviews customer initiated customer orders. The sales manager checks customer credit by reviewing the customer database. The sales manager keys in either an acceptance or denial of the customer order, entering a sales order into the sales database when approved. The customer is notified electronically through a transmission from the sales system. If the order is accepted, this transmission takes the form of an electronic sales order; if it is rejected, the transmission is simply an electronic mail message of denial.

Goods are shipped to the customer within 3 days, a printout of the authorized sales order is attached, acting as a packing slip. The shipping department keys the sales order information into the sales database to make sure the shipment is authorized. They then record the sales order as shipped in the sales database. Goods are at times not available—thus out of stock. If the warehouse crew is unable to locate the item requested by the customer, or a suitable substitute, no shipment takes place. The customer receives an email asking them if they wish to wait for the item to arrive from the supplier and be shipped to them.

At the beginning of the following day, the cash receipts officer connects to the sales database to review the shipped goods, and updates the accounts receivable balances. Per agreement with customers, all payments are due within 30 days after receipt of shipped athletic goods. Customers epay for merchandise by credit card or bank transfers. When a customer pays by credit card (or bank transfer), they email their credit card (or bank) information to Lakers Athletics on a credit card (or bank) authorization form. Lakers uses this information to request payment from the National Credit Card Bank (or customer bank). When approved, a monetary transfer is received from the National Credit Card Bank (or customer bank) to Lakers Athletics’ local bank. A confirmation number is received from the local bank, and the cash receipts officer enters the confirmation number into the sales database. This event serves to confirm completion of the payment from the customer.
