A method and system are provided to permit a network operator to capture transaction data relating to transactions between a subscriber and a service provider that are conducted via a communications network established by the network operator, such as a cable television network. In operation, the subscribers are provided with information relating to items offered by one or more service providers. The subscriber can transmit a purchase order. A headend of the communications network receives and analyzes the purchase order to capture transaction data. If the service provider is different than the network operator, the headend also relays a copy of the purchase order to the third party service provider such that the purchase order can be filled. Since the network operator has captured information relating to the purchase order, however, the network operator can charge the service provider and/or the subscriber for utilizing its network to facilitate the transaction.
