In the early 1980s, most chamber of commerces used manual systems to maintain membership lists, handle member dues and billing and perform general accounting functions. In 1984, after studying the problem and conducting market research, Chamber Data Systems developed the first comprehensive and integrated personal-computer software tailored specifically for chamber of commerces. This software, CC-Assist, is one of the most powerful, reliable and easy-to-use packages available. Since its introduction, more than 750 chamber of commerces have chosen the CC-Assist as their primary administrative tool, making it the most widely used software for chamber of commerces in the United States. Chamber Data Systems has an office in Dallas.
