Federal Agency Contracting FAQs
Which federal agency spends the most on contracts?
The Department of Defense (DoD) is by far the largest federal buyer, with annual contract obligations exceeding $450B — roughly two-thirds of all federal contract spending. After DoD, the largest civilian buyers are HHS ($28B+), VA ($35B+), DHS ($25B+), DOE ($32B+), and NASA ($22B+).
How do I find opportunities at a specific federal agency?
Start with SAM.gov, which is the official source for all federal opportunities. Each agency also has its own forecasts, vendor outreach programs, and agency-specific platforms (e.g., NASA NAIS, VA TAC, DLA DIBBS, GSA eBuy). Many agencies also publish 12-month forecasts of upcoming acquisitions.
What are GWACs and why do they matter?
Government-Wide Acquisition Contracts (GWACs) are multi-agency vehicles that let any federal agency buy from approved primes without running a new solicitation. Major GWACs include GSA MAS, Alliant 2, OASIS+, CIO-SP4, SEWP VI, and Polaris. Holding a GWAC seat significantly improves opportunity access.
Which agencies have the best small business participation?
VA is the leader for SDVOSB/VOSB through its Veterans First Contracting Program. SBA, GSA, and HHS consistently exceed small business goals. DoD, despite being the largest, achieves ~25% small business participation through extensive set-asides across service branches.
