Service Business

The tertiary sector of economy (also known as the service sector or the service industry) is one of the three economic sectors, the others being the secondary sector (approximately manufacturing) and the primary sector (extraction such as mining, agriculture and fishing). Sometimes an additional sector, the "quaternary sector", is defined for the sharing of information (which normally belongs to the tertiary sector).

The tertiary sector is defined by exclusion of the two other sectors. Services are defined in conventional economic literature as "intangible goods".The tertiary sector of economy involves the provision of services to businesses as well as final consumers. Services may involve the transport, distribution and sale of goods from producer to a consumer as may happen in wholesaling and retailing, or may involve the provision of a service, such as in pest control or entertainment.

Goods may be transformed in the process of providing a service, as happens in the restaurant industry or in equipment repair. However, the focus is on people interacting with people and serving the customer rather than transforming physical goods.Economies tend to follow a developmental progression that takes them from a heavy reliance on agriculture and mining.

Toward the development of manufacturing (e.g. automobiles, textiles, shipbuilding, steel) and finally toward a more service based structure. Whereas the first economy to follow this path in the modern world was the United Kingdom, the speed at which other economies have later made the transition to service-based, sometimes called post-industrial, has accelerated over time.
