A chamber of commerce is a form of business network, e.g., a local organization of business whose goal is to further the interests of businesses. business owners in towns and cities form these local societies to advocate on behalf of the business community. Local businesses are members, and they elect a board of directors or executive council to set policy for the chamber. The board or council then hires a President, CEO, or Executive Director, plus staffing appropriate to size, to run the organization.

A trade association, also known as an industry trade group, business association, or sector association is an organization founded and funded by businesses that operate in a specific industry. An industry trade association participates in public relations activities such as advertising, education, political donations, lobbying, and publishing, but its main focus is collaboration between companies, or standardization. Associations may offer other services, such as producing conferences, networking or charitable events or offering classes or educational materials. Many associations are non-profit organizations governed by bylaws and directed by officers who are also members.
