A group initiative that enables the establishment and control of a group by members of the group, while allowing the personalized requirements of individual members to be maintained as the group pursues the advantages of the collective bargaining power of the group as a whole. One aspect of the present invention is a group initiative for collective bargaining for purchases. Buyers in a particular purchasing group maintain their individuality by defining differing purchasing requirements such as product or service specifications, contract terms, delivery schedules, etc. while they simultaneously present themselves as a cohesive and committed group to the seller community. Sellers also maintain individuality in responding to each buyer in the group with different pricing based on each buyer's requirements and buying profile considering such factors as volumes purchased, payment terms and cost of servicing each potential account in the group.
