Cleary Industries has been supplying electronic surveillance equipment to the U.S. Military and NSA for over 50 years. Clearys original products allowed for more effective electronic surveillance during the Vietnam War and the company has continued to be a leader in this technology. However, other companies have begun to erode Clearys market position. Consequently, Cleary has decided to enter the corporate security market. Specifically, Cleary is providing high-end security for corporate clients. To attract business, Cleary is selling the systems for no money down and no payments or interest for 12 months. After the twelve months, customers pay off their balance in 36 equal payments ranging from $25,000 to $120,000 per month depending on the system. Cleary has no previous experience with sales to the corporate market. Michael Cleary, the CEO, realizes that some accounts will fail to pay their entire balance and wants to know how to account for these accounts.
