Quick Answer

Government-Wide Acquisition Contracts (GWACs) are pre-competed IDIQ contracts that any federal agency can use to buy IT products and services. Major GWACs include STARS III (8(a)), Alliant 2 (large business), OASIS+ (professional services), and CIO-SP4 (IT solutions). GWACs provide access to multiple agencies through a single contract vehicle.

What is a GWAC?

A Government-Wide Acquisition Contract (GWAC) is a task-order or delivery-order contract for information technology established by one agency for government-wide use. GWACs are indefinite-delivery, indefinite-quantity (IDIQ) contracts that any federal agency can use to procure IT solutions.

Unlike agency-specific contracts, GWACs are "government-wide," meaning any agency can place orders. This provides contractors with access to a broader customer base while giving agencies a streamlined procurement vehicle.

Key GWAC Characteristics

  • Pre-competed: Competition occurs at GWAC award, not every order
  • Government-wide: Any federal agency can place orders
  • IDIQ structure: Base contract with individual task orders
  • IT-focused: Must be for information technology products/services
  • OMB designation: Must be approved by Office of Management and Budget

Winning Task Orders

Having a GWAC is just the first step—the real revenue comes from winning task orders.

Monitor Opportunities

Track task order solicitations through the GWAC program office portal, SAM.gov, and agency procurement forecasts.

Build Relationships

Engage with agency program offices before task orders are released. Understand their needs and position yourself.

Respond Quickly

Task order competitions often have compressed timelines (10-30 days). Have response processes ready.

Competitive Pricing

Task orders are competed among pre-qualified holders. Price competitiveness matters significantly.

FAR 16.505 Fair Opportunity

For task orders over $4,500, agencies must provide all GWAC holders a fair opportunity to compete, unless an exception applies:

  • • Only one source is capable
  • • Urgent need exists

Success Strategies

Start Early

Major GWACs are announced years in advance. Begin building required past performance and capabilities early.

Multiple Vehicles

Hold positions on multiple GWACs to maximize opportunities. Different GWACs serve different agency preferences.

Dedicated BD Team

Assign staff specifically to monitor and pursue task orders. Task order volume justifies dedicated resources.

Teaming Strategy

Team with other GWAC holders to combine capabilities and share task order opportunities.

Agency Focus

While GWACs are government-wide, focus on agencies where you have relationships and relevant experience.

Performance Excellence

Excellent task order performance leads to follow-on work and referrals across agencies.

Frequently Asked Questions

What's the difference between a GWAC and GSA Schedule?

GSA Schedules are catalog contracts for commercial items available to any company meeting requirements. GWACs are competed contracts with limited holders, focused on IT solutions, and require significant past performance.

Can small businesses compete for GWACs?

Yes, most GWACs have dedicated small business pools or are exclusively for small businesses (like STARS III for 8(a) firms). Small business set-aside pools compete only against other small businesses.

How are task orders distributed among holders?

There's no automatic distribution. Each task order is competed among holders (fair opportunity). Success depends on your capability, price, and relationship with the ordering agency.

What if I miss the GWAC competition?

Most GWACs have "on-ramp" opportunities allowing new contractors to compete for positions after initial award. Watch for on-ramp announcements and prepare to compete.

Can I subcontract under a GWAC?

Yes, if you're not a prime GWAC holder, you can partner with holders as a subcontractor on task orders. Many small businesses build experience this way before pursuing prime positions.
