Contract Vehicle FAQs
What is the difference between a GWAC and an IDIQ?
A Government-Wide Acquisition Contract (GWAC) is a multi-agency IDIQ that any federal agency can buy from without running a separate procurement. A stand-alone IDIQ is single-agency or limited-agency. GSA MAS (Schedule), CIO-SP4, SEWP VI, Alliant 2, OASIS+, and Polaris are GWACs. ITES-3S (Army) and SeaPort-NxG (Navy) are agency-specific IDIQs.
Which contract vehicle is best for federal IT services?
It depends on your firm size, target agencies, and capability mix. For broad cross-agency access, GSA Schedule is the entry vehicle. For high-value federal IT, Alliant 2 (unrestricted) and Polaris (small business) are dominant. For HHS work, CIO-SP4. For Army, ITES-3S. For Navy, SeaPort-NxG. SEWP VI is the dominant IT product vehicle with strong cross-agency reach.
How do I win a seat on a federal contract vehicle?
GSA Schedule has continuous on-ramp — apply any time. Stand-alone GWACs (Alliant 2, OASIS+, Polaris) have competitive on-ramps held every 5-10 years. Agency-specific IDIQs vary; SeaPort-NxG has the most-frequent on-ramp at twice per year. Winning requires substantial proposal investment — past performance, key personnel, technical solution, and competitive pricing all matter.
Can a small business hold multiple federal contract vehicles?
Yes — and most successful federal IT primes hold 3-5+ vehicles. The strategic constraint is task order pursuit capacity, not vehicle holding. Most small firms start with GSA Schedule, add Polaris if eligible, and target one agency-specific IDIQ aligned with their primary customer.
