A network system for managing an on-demand service can receive, from a user, a service request indicating a destination location. In addition to facilitating available service providers to fulfill the service request, the network system can create and manage a session for the user for an entity identified based on, for example, the destination location. The session for the user can be used to procure items and/or services provided by the entity. The network system can transmit, to terminal computing system(s) associated with the entity, session initiation data that includes user data such as identification information to identify the user. The transmission of the session initiation data can cause the terminal computing system(s) to automatically create the session for the user. In addition, the network system can receive, from the terminal computing system(s), session data upon termination of the session for the user.
