The host computer mainframe is located at corporate headquarters with interactive, remote job-entry terminals at each branch location. In general, data entry occurs at the source and is transmitted to an integrated database maintained on the host computer. Data transmission is made between the branch offices and the host computer over leased telephone lines. The software allows flexibility for managing user access and editing data input. Procedures for Purchasing Raw Materials Production orders and appropriate bills of materials are generated by the host computer at corporate headquarters. Based on these bills of materials, purchase orders for raw materials are generated by the centralized purchasing function and mailed directly to the vendors. Each purchase order instructs the vendor to ship the materials directly to the appropriate manufacturing plant. Assuming that the necessary purchase orders have been issued, the manufacturing plants proceed with the production orders received from corporate headquarters. When goods are received, the manufacturing plant examines and verifies the count with the packing slip and transmits the receiving data to accounts payable at corporate headquarters. In the event that raw material deliveries fall behind production, each branch manager is given the authority to order materials and issue emergency purchase orders directly to the vendors. Data

about the emergency orders and verification of materials receipt are transmitted via computer to accounts payable at corporate headquarters. Because the company employs a computerized perpetual inventory system, physical counts of raw materials are deemed not to be cost effective and are not performed.
Accounts Payable Procedures

Vendor invoices are mailed directly to corporate headquarters and entered by accounts payable personnel when received; this often occurs before the receiving data are transmitted from the branch offices. The final day of the invoice term for payment is entered as the payment due date. This due date must often be calculated by the data entry person using information listed on the invoice. Once a week, invoices due the following week are printed in chronological entry order on a payment listing, and the corresponding checks are drawn. The checks and the payment listing are sent to the treasurer’s office for signature and mailing to the payee. The check number is printed by the computer and displayed on the check, and the payment listing is validated as the checks are signed. After the checks are mailed, the payment listing is returned to accounts payable for filing. When there is insufficient cash to pay all the invoices, certain checks and the payment listing are retained by the treasurer until all checks can be paid. When the remaining checks are mailed, the listing is then returned to accounts payable. Often, weekly check mailings include a few checks from the previous week, but rarely are there more than two weekly listings involved. When accounts payable receives the payment listing back from the treasurer’s office, the expenses are distributed, coded, and posted to the appropriate plant or cost centre accounts. Weekly summary performance reports are processed by accounts payable for each cost centre and branch location reflecting all data entry to that point.
