ADP, LLC., is an American provider of human resources management software and services. ADP was formerly one of four American companies to get a AAA credit rating from Standard & Poor's (S&P) and Moody's, but S&P and Moody's downgraded ADP to AA in April 2014, after the dealer services unit spin off.
In 1949 Henry Taub founded Automatic Payrolls, Inc. as a manual payroll processing business with his brother Joe Taub. Frank Lautenberg joined the brothers in the company's infancy. In 1952, Lautenberg became Chairman and CEO of the company. In 1957, the company changed its name to Automatic Data Processing, Inc. (ADP), and began using punched card machines, check printing machines, and mainframe computers. ADP went public in 1961 with 300 clients, 125 employees and revenues of approximately US$400,000. The company established a subsidiary in the United Kingdom in 1965 and acquired the pioneering online computer services company Time Sharing Limited (TSL) in 1974. Lautenberg continued in his roles as Chairman and CEO until elected to the United States Senate from New Jersey in 1982.
From 1985 onward, ADP’s annual revenues exceeded the $1 billion mark, with paychecks processed for about 20% of the U.S. workforce. In the 1990s, ADP began acting as a professional employer organization (PEO). Around this time, the company acquired Autonom, a German company and the payroll and human resource services company, GSI, headquartered in Paris. Kerridge Computer Co. Ltd., a dealer management systems (DMS) provider to auto dealers in the UK was acquired in 2006.
In September 1998, ADP acquired UK-based Chessington Computer Centre that supplied administration services to the UK Government.
