Architect’s Depot (AD) is an online company that supplies a range of architectural products to building contractors and private individuals. Its product line includes such items as gable vents, shutters, vinyl sidings, and decorative trim in various materials.

The company employs a combination of manual procedures and a networked accounting system with distributed terminals in several departments. After years of satisfactory performance, however, AD is now experiencing operational inefficiencies and accounting errors. Your firm has been hired to evaluate AD’s business processes and internal controls. AD’s expenditure cycle is described in the following paragraphs.

Purchase System Procedures

AD’s purchase transactions are initiated when the purchasing department clerk reviews the inventory file for items that need to be replenished. The clerk selects a vendor, adds a record to the digital PO File, and prints four hard copies of the purchase order. One copy is filed in the department; the second copy is sent to the receiving department; the third copy is sent to the AP department; and the final copy is sent to the vendor.

When the goods and the packing slip arrive at the receiving department, the receiving clerk examines the items for condition and verifies the quantities received against the packing slip. Upon completion of the inspection, the clerk manually creates two hard copies of a receiving report. One copy is filed in the department and the second accompanies the goods to the warehouse.

In the warehouse, the clerk receives and shelves the goods. In addition, the clerk updates the inventory file by posting the amounts received to the various inventory records affected.

When the AP department clerk receives the invoice from the supplier, he visually matches it to the hard-copy purchase order on file. The clerk then adds a record to the vendor invoice file, which serves as the AP subsidiary ledger and sets a due date for payment.

Finally, at the end of each day, the warehouse clerk and the AP clerk create digital journal vouchers to reflect the day’s transactions. The system automatically posts the journal vouchers to the relevant GL control accounts.
