A method for flexible billing provides for a service provider to apportion billing for one or more services among a number of parties. The services may be shared among the parties and the bill may be apportioned in accordance with an apportioning scheme, or billing breakout as determined by the parties. The parties may designate a coordinator to administer the service and serve as the contact point between the parties and the service provider. The flexible billing can also provide for one party to pay a portion of the service charges for one or more other parties. Incentives in the form of reduced charges may be provided by the service provider.
