Small businesses often join or come together to form organizations to advocate for their causes or to achieve economies of scale that larger businesses benefit from, such as the opportunity to buy cheaper health insurance in bulk. These organizations include local or regional groups such as Chambers of Commerce and independent business alliances, as well as national or international industry-specific organizations.

Such groups often serve a dual purpose, as business networks to provide marketing and connect members to potential sales leads and suppliers, and also as advocacy groups, bringing together many small businesses to provide a stronger voice in regional or national politics. In the case of independent business alliances, promoting the value of locally owned, independent business (not necessarily small) through public education campaigns is integral to their work.

The largest regional small business group in the United States is the Council of Smaller Enterprises, located in Greater Cleveland. United Kingdom trade and Investment (www.ukti.gov.ih) gives out research in different markets around the world, also research in program planning and promotional activities to exporters. The BEXA (British Exporters Association) role is to connect new exporters to expert services, it can provide details about regional export contacts, who could be made informally to discuss issues.
