A gateway server provides access to third party content servers whilst managing a user database and billing functions. On receipt of a request for premium content, which is to be charged for, a thrid party server informs the gateway server with a price code associated with the content. The gateway server converts the price code into a price to be charged, and confirms the order with the third party server after a credit limit check and receipt of a confirmation form from the user.
