LOCKBOX SYSTEM Hardin-Gehr Corporation (HGC) began operations 5 years ago as a small firm serving customers in the Detroit area. However, its reputation and market area grewquickly. TodayHGC has customers all over theUnited States.Despite its broad customer base, HGC has maintained its headquarters in Detroit; and it keeps its central billing system there. On average, it takes 5 days from the time customers mail in payments until HGC can receive, process, and deposit them. HGC would like to set up a lockbox collection system, which it estimates would reduce the time lag from customer mailing to deposit by 3 days—

bringing it down to 2 days. HGC receives an average of $1,400,000 in payments per day.
