Abstract: An apparatus, method, and computer program are provided which allows service requesters to receive services from a single provider which can efficiently coordinate and cause the delivery of a requested service through a network, e.g. the Internet. Further the service is provided without compatibility obstacles and in which the requester can also use their preferred service providers. A request for service is made through the network to an application server which determines, from among a plurality of registered functional entities with the application server, which functional entity to route the request to. The functional entity may be an on-line or an off-line functional entity, i.e., an on-line or an off-line business. The functional entity produces output that is transmitted, either through the network or physical delivery, back to the requester and/or the application server. The application server can also use functional entities to transform incompatible data to requester, compatible data.
