A method and system for automated bargaining in a round by round manner is disclosed. The method and system are capable of multiple rounds. The method and system are used in testing non-equal values in normal rounds for satisfaction of a predetermined criterion. If the criterion is not satisfied in the normal rounds, power round values are tested for satisfaction of a power round criterion. If the power round criterion is satisfied, a binding bargained payment is calculated. Additional options involve an automated facilitator, windfalls to initiators, automatic payment initiation, multiparty aggregation and automatic agreement document generation.
