A system and method automates and simplifies tasks associated with setting up a user self-activating network-based service. A configurable input engine is configured to define the service. The service may, for example, use a plurality of networking devices and/or computing devices. After the service is defined, an offer of the service is published to a user. The offer includes values of commercial terms and/or values of configuration parameters associated with the offer. Upon receiving an acceptance of the offer from the user, the configurable input engine automatically generates activations for the devices to be used by the service. The activations are sent to policy distribution points (PDPs) where the activations are translated into device-specific instructions. The device-specific instructions are in turn sent to the devices (networking devices and/or computing devices) to be configured. The device-specific instructions configure the devices, thereby automatically setting up the service for the user.
