Garner Industries manufactures precision tools. The firm uses an activity-based costing system. CEO Deb Garner is very proud of the accuracy of the system in determining product costs. She noticed that since the installment of the ABC system 10 years earlier, the firm had become much more competitive in all aspects of the business and earned an increasing amount of profits every year.

In the last two years, the firm sold 0.658 million units to 2,500 customers each year. The manufacturing cost is $700 per unit. In addition, Garner has determined that the order-filling cost is $51.16 per unit. The $960.00 selling price per unit includes 20% markup to cover administrative costs and profits.

The order-filling cost per unit is determined based on the firms costs for order-filling activities. Order-filling capacity can be added in blocks of 60 orders. Each block costs $120,000. In addition, the firm incurs $1,300 order-filling costs per order.

Garner serves two types of customers designated as PC (Preferred Customer) and SC (Small Customer). Each of the 100 PCs buys, on average, 5,000 units in two orders. The firm also sells 158,000 units to 1,000 SCs. On average each SC buys 158 units in 10 orders. Ed Cheap, a buyer for one PC, complains about the high price he is paying. Cheap claims that he has been offered a price of $800 per unit and threatens to take his business elsewhere. Garner does not give in because the $800 price Cheap demands is below cost. Besides, she has recently raised the price to SC to $908.86 per unit and experienced no decline in orders.
