A catalog company has hired you to computerize its sales order entry forms. Approximately 60 percent of all orders arc received over the telephone, with the remainder received by either mail or fax. The company wants the phone orders to be input as they are received. The mail and fax orders can be batched together in groups of 50 and submitted for keypunching as they become ready. The following information is collected for each order
Customer number (if customer does not have one, one needs to be assigned)
Customer name
Address
Payment method (credit card or money order)
Credit card number and expiration date (if necessary)
Items ordered and quantity
Unit price

Required
Determine control techniques to make sure that all orders are entered accurately into the system. Also, discuss any differences in control measures between the batch and the real-time processing.
