Beds and Spreads, Inc. specializes in bed and bath furnishings. Its inventory system is linked through the Internet to key suppliers. The auditor identified the following internal controls in the inventory cycle:
1. The computer initiates an order only when perpetual inventory levels fall below prespecified inventory levels in the inventory master file.
2. The sales and purchasing department managers review inventory reorder points on a monthly basis for reasonableness. Approved changes to reorder points are entered into the master file by the purchasing department manager and an updated printout is generated for final review. Both managers verify that all changes were entered correctly and initial the final printout indicating final approval. These printouts are maintained in the purchasing department.
3. The computer will initiate a purchase order only for inventory product numbers maintained in the inventory master file.
4. The purchasing department manager reviews a computer-generated exception report that highlights weekly purchases that exceed $10,000 per vendor.
5. Sales clerks send damaged merchandise on the store shelves to the back storage room. The sales department manager examines the damaged merchandise each month and prepares a listing showing the estimated salvage value by product number. The accounting department uses the listing to prepare a monthly adjustment to recorded inventory values.
