During the 1950s, Cass developed a service to streamline the payment of freight bills. Over time, the bank began marketing its “Freight Payment Plan” services nationwide to companies that found the process of examining and paying freight bills a cumbersome and costly undertaking. Using automation and paying close attention to its customers’ needs, Cass was able to streamline the process, and this business grew significantly.
In 1974, Harry Hartkopf, who served as CEO for almost 40 years, retired. He was succeeded by Harry Krieg, who became CEO in 1969 and later chairman. By 1984, to formally distinguish the bank’s freight invoice processing service from its traditional commercial banking business, the processing business was incorporated as Cass Information Systems (CIS) and was led by Larry Collett, chairman and CEO. By 1993, CIS moved from downtown St. Louis to its new building on Hollenberg Drive in Bridgeton, Missouri.
After 84 years in the City of St. Louis, the Cass Bank headquarters relocated to St. Louis County in 1990. In 1997, Cass Bank moved into the recently expanded facility in Bridgeton, Missouri, which was also home to CIS.
In 1998, Cass Bank & Trust Company formally changed its name to Cass Commercial Bank, reflecting its ongoing commitment to businesses in St. Louis. At about the same time, a specialized team was formed to serve the banking needs of religious organizations nationwide. In November 2004, Cass found an opportunity to establish a west coast presence by purchasing a single-location bank, Franklin Bank of California.
