About this vehicle
NASA's Shared Services Center awarded the Contract Audit Support Services (CASS) Master IDIQ on October 21, 2021, with a shared ceiling of $55 million and final order authority expiring October 20, 2026—now three months away. Ninety-one task orders have been issued across seven prime contractors, with $10.4 million obligated against a combined potential value of $11.6 million (90% utilization). The vehicle is heavily concentrated: Castro & Company, LLC holds $7.3 million in potential value across just five orders, while Tichenor & Associates, LLP leads by order count with 21 awards totaling $1.1 million. The remaining five primes—Deva & Associates PC, Regis & Associates PC, Booth Management Consulting LLC, Reed & Associates CPAs Inc., and others—collectively represent $2.3 million. All 91 task orders fund NASA Shared Services Center procurement operations.
The vehicle procures incurred cost audits, forward pricing rate proposal audits, cost accounting standards compliance reviews, claim and termination audits, and contract audit support for over 170 NASA contractors not audited by the Defense Contract Audit Agency. Awarded task orders are primarily firm-fixed-price incurred cost audits and accounting system audits. Typical task-order values range from approximately $14,000 to $308,000, though two standout orders dominate: Task Order 12 to an 8(a) awardee carries a ceiling of $4.976 million (obligated $3.856 million) and Task Order 9 to an 8(a) awardee totals $2.166 million obligated. All remaining orders fall below $200,000.
Ninety-three percent of task orders carry no set-aside designation; the remaining 7 percent (six orders) are set aside for small business, including the two mega-orders to 8(a) contractors. Ordering velocity has slowed sharply—30 orders in 2022, 23 in 2023, only 8 in 2024, 17 in 2025, and 2 year-to-date in 2026—reflecting the vehicle's age and imminent expiration. With three months of ordering authority remaining and 90 percent of potential value already obligated, new task order opportunities are limited.
