Service is an intangible task that satisfies the needs of consumers or business users. Service is an activity or benefit that one person can offer to another which is essentially intangible and does not result in ownership of anything. Service is an activity or benefit offered to consumers or service users so that it can satisfy or meet consumer needs and desires. Services in general are intangible and cannot be fully owned by consumers. Consumers pay in return for the convenience, service and satisfaction they receive from the service, not for ownership of the service.
