A method of establishing a telecommunication service over a communication network between a user and a telecommunications services agent using a computer terminal. The method includes providing information regarding the telecommunication service to the user, by the agent interacting with a customer service application. The method also includes retrieving information regarding complementary services that are related to the telecommunication service, by the agent interacting with the customer service application, and describing the retrieved information regarding the complementary services to the user. The method further includes automatically checking, by the customer service application, to determine if a computer terminal entry has been made by the agent indicating that the user has acknowledged receiving the information regarding complementary services, and establishing the telecommunication service for the user only when the customer service application indicates that the user has acknowledged receiving the information regarding the complementary services.
