A business service is defined as the externally visible ("logical") functionality, which is meaningful to the environment and is realized by business behaviour (business process, business function, or business interaction).

A business service exposes the functionality of business roles or collaborations to their environment. This functionality is accessed through one or more business interfaces. A business service is realized by one or more business processes, business functions, or business interactions that are performed by the business roles or business collaborations, respectively.

The name of a business service should preferably be a verb ending with "-ing"; e.g., "transaction processing". Also, a name containing the word "service" may be used.
