Multiple Award Contract (MAC)

Definition

Multiple Award Contract (MAC) is a generic term for any contract — typically an IDIQ — in which multiple vendors receive a prime position from which they compete for future task or delivery orders. Examples include multiple-award IDIQs, multiple-award Schedules, and multiple-award BPAs. MAC structures balance competition (task-order mini-competitions) with speed (no new source selection required). FAR 16.505 governs task-order competition under multiple-award IDIQs, including the 'fair opportunity' requirement.

Why It Matters

A MAC seat is an annuity asset: once on, you have years of access to task-order competitions against a limited field. MAC on-ramps are competitive and infrequent, so missing a cycle can lock you out of a major market segment for 5–10 years. MACs also trigger specialized capture disciplines: short-duration proposals, recurring past performance citations, and tight pricing games among a small pool of informed competitors.

Example

An agency issues a 5-year MAC to 12 prime holders. Task orders totaling $1.2B flow over the period. Each task order is competed only among the 12 primes. A firm winning one of those 12 seats competes for a much smaller pool than it would in the open market.
