Aspects of the present application provide a system and method for credit limit-based provisioning of network usage advances in which network usage advances are provisioned based on available credit limit. The method may include determining a subscriber score associated with a subscriber record stored in a database and determining a value of a credit limit associated with the subscriber record. In response to provisioning a network usage advance to an account associated with the subscriber record, the credit limit value is updated by deducting a value associated with the network usage advance from the credit limit value. The network usage advance enables mobile telephone network usage in advance of received payment and provisioning the network usage advance includes recording the network usage advance value as outstanding. A further network usage advance is available to the subscriber for a value less than or equal to the updated credit limit value.
