What is a solicitation for a single contract or order that consolidates requirements for supplies or services from multiple contracts called?

A solicitation for a single contract or order that consolidates requirements for supplies or services from multiple contracts is known as a consolidation (or a consolidated requirement). This term is used to describe the process of combining various procurement needs into a single request for bids or proposals, streamlining the procurement process and potentially achieving economies of scale.

By consolidating requirements, organizations can reduce administrative costs, minimize duplication of contracting efforts, and leverage better pricing due to larger volume purchases. This is particularly beneficial when multiple departments or units within the organization have similar needs for products or services, as it ensures that they can jointly fulfill their requirements more efficiently.

The other options such as joint procurement, aggregation request, and order consolidation refer to related concepts but do not specifically emphasize the aspect of consolidating contract requirements into a single solicitation as directly as the term "consolidation" does. Joint procurement is often associated with collaborative purchasing between different entities, while aggregation and order consolidation might involve bundling purchases but do not capture the formal solicitation aspect in the same way. Therefore, "consolidation" is the most accurate term in this context.
