Demand Aggregation

Strategy & Operations

Definition

Combining requirements from multiple buyers, sites or periods to purchase in larger, more economical volumes.

Explanation

Aggregating demand increases leverage, unlocks volume discounts and reduces transaction and delivery costs. It requires visibility of dispersed needs and coordination to time purchases together — a core reason organisations centralise or run group buying.

Example

Demand aggregation combines every site's uniform order into one annual contract at a lower unit price.
