Marley Company sells supplies to a variety of customers. Marley Company uses an ERP system for all of its business processes. Marley employs the following for billing and cash receipts process. The billing process begins each morning when a clerk in the billing section of the accounts receivable department requests that the ERP system display the billing due list on their computer screen. These are the shipments made the previous day from the warehouse at Marley's customer fulfillment center. At the bottom of the list, the computer displays the total number of records in the billing due list, the total number of items that were shipped, and a hash total of the customer numbers. The clerk records these onto a batch total sheet. The clerk then requests that the ERP system execute the billing program. This program prepares invoice records by accessing the customer data to get the routing information for the electronic invoice and the payment terms to be give to the customer. The program also obtains the prices for the inventory data. Finally, the program examines the sales order data to determine how the shipment was routed so that shipping costs can be added to the invoice. At the end of this process, the computer calculates and displays a total of the number of invoices, the total items being billed, and a hash total of the customer numbers in the batch of invoices. The billing clerk reconciles the invoice totals with those obtained from the billing due list. If the totals agree, the clerk accepts the batch of invoices. In response, the ERP system updates the sales order to show that the shipment has been billed, closes the billing due list, creates and accounts receivable record, updates the general ledger for the sale, sends an electronic invoice to the customer, and displays a job completed notice on the billing clerk's screen.
