Services
the providing or a provider of accommodation and activities required by the public, as maintenance, repair, etc.
the organized system of apparatus, appliances, employees, etc., for supplying some accommodation required by the public
ISIC Annotated note :
This includes a variety of activities that support general business operations; including financial service activities, and activities of holding assets, 
(Services also…) include specialized professional, scientific and technical activities. These activities require a high degree of training, and make specialized knowledge and skills available to users.
Service Industries – Broad definition:
The service sector consists of the parts of the economy, i.e. activities where people offer their knowledge and time to improve productivity, performance, potential, and sustainability, which is termed as affective labor. The basic characteristic of this sector is the production of services instead of end products. Services (also known as "intangible goods") include attention, advice, access, experience, and discussion. The production of information has long been regarded as a service, but some economists now attribute it to a fourth sector, the quaternary sector.
The tertiary sector of industry involves the provision of services to other 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.
The tertiary sector or service sector is the third of the three economic sectors of the three-sector theory. The others are the secondary sector (approximately the same as manufacturing), and the primary sector (raw materials).
Note on the difficulty of definition:
It is sometimes hard to define whether a given company is part of the secondary or tertiary sector. And it is not only companies that have been classified as part of that sector in some schemes; government and its services such as police or military, and non-profit organizations such as charities or research associations can also be seen as part of that sector.
In order to classify a business as a service, one can use classification systems such as the United Nations' International Standard Industrial Classification standard, the United States' Standard Industrial Classification (SIC) code system and its new replacement, the North American Industrial Classification System (NAICS), the Statistical Classification of Economic Activities in the European Community (NACE) in the EU and similar systems elsewhere. These governmental classification systems have a first-level hierarchy that reflects whether the economic goods are tangible or intangible.
