The invention relates to a method for billing for chargeable services by means of a prepaid account (GK) which is kept in a communication network by an account-keeping device (KFE) for a communication terminal (KEG) registered in the communication network. To account also for services offered by an independent provider by using the prepaid account (GK), a payment request device (ZAE) which is not under the control of an operator of the communication network sends a payment request (3) to a payment system (ZS) associated with the communication network, the payment request (3) containing an identification of the communication terminal (KEG) and a payable amount, the payment system (ZS) determines addressing data of the account-keeping device (KFE) of the prepaid account (GK) by using the identification, and the payment system (ZS) sends a billing message (7) to the account-keeping device (KFE) identified by the addressing data, in order to deduct the payable amount from the prepaid account (GK).
