Abstract: A method of assisting delivery of useful services that contribute to improvement of people's standard of living. The method starts with providing, via a network, information about paid services to a customer who has signed up for membership with payment of a predetermined fee. A purchase order for one of the paid services is received from the terminal of the customer which is connected to the service delivery support system via the network. The customer's creditworthiness is evaluated, based on the amount of the predetermined fee that has been paid by the customer, thus determining how much on-behalf payment can be offered to the customer in payment for the paid service that the customer has ordered. The customer is notified of the determined amount of on-behalf payment.
