Order Processing System for Restaurant Representatives

1. 1 2 3 4 8 9 10 11 12 6 5 13 7 From a client restaurant a representative will pick up a signed order sheet from the restaurant manager for the quantities desired of each item sold by ERA. From his (her) car, the representative connects to ERA’s order processing computer package using a laptop computer and a cellular phone. The representative enters the customer number into the computer; and then enters item numbers and quantities of each item requested. The computer captures the customer number and order information and then reads the accounts receivable master file to verify that the customer has sufficient credit to allow the transaction. If the transaction is allowed, the computer then displays an approval screen on the representative’s computer and records the sales information in a “sales order database” and prints two copies of the sales order on a laser printer in the representative’s car. The representative reconciles the printed sales order to the request he keyed in and then enters a code into the computer to execute the sales transaction. When the representative enters the code, the computer updates the sales order database and the accounts receivable master file to reflect the execution. The representative takes a copy of the sales order to the manager of the restaurant. 1, 2, 3, 4, 8, 9, 10, 11, 12, 5, 6, 13, 7
