A business is an individual or organisation that makes goods or provides services. Examples of businesses include supermarkets and hairdressers.
A business can provide both goods or sevices:
Goods are physical products that can be seen or touched. Examples of what are called tangible goods are a television, chocolate bar or a hairdryer.
Services are provided by businesses but cannot be seen or touched. Examples of what are called intangible services are cutting hair, driving a taxi to take people somewhere, or screening a film in cinema.
