Most Federal Money Never Becomes an Open RFP: A Practical Guide to Federal Contract Vehicles for Small Business

You've done everything "right." You're registered in SAM.gov, you check it every morning, and you've bid on a dozen RFPs this year. Yet the opportunities that fit you best keep showing up as awards to companies you never saw competing. 

You're not imagining it. A lot of that work never became an open RFP. It moved through a contract vehicle you weren't on. 

This post kicks off our new series, Follow the Money, Read the Fine Print, and it starts where the money starts. 

According to the Congressional Research Service, in FY2024 roughly 56% of Defense Department contract dollars and 63% of non-DoD contract dollars were obligated on indefinite delivery vehicles, which include IDIQ contracts. 

These vehicles are pre-competed express lanes: 

• the GSA Multiple Award Schedule (MAS); 

• governmentwide acquisition contracts (GWACs) like 8(a) STARS III; 

• blanket purchase agreements (BPAs); 

• agency IDIQs. 

Terms, labor rates and vendor vetting are settled up front, so an agency can place a task order in weeks instead of running a months-long full-and-open competition. The GAO found flexibility and speed are the main reasons agencies choose these contracts. 

The catch is that when a task order goes out under a vehicle, generally only the vehicle holders see it. GSA eBuy, for example, is open only to Schedule contractors. If you're not on the vehicle, and you're not teamed with someone who is, you aren't losing those competitions. You were never in the room. 

This matters more in 2026 than ever. Executive Order 14240 directed agencies to consolidate buying of common goods and services at GSA and named GSA the executive agent for IT GWACs. 

The effects are real. NITAAC cancelled the $50 billion CIO-SP4 GWAC after years of protests, and HHS is sunsetting all NITAAC GWACs, including CIO-SP3, on October 29, 2026. NITAAC's director told Federal News Network that a review found more than 90% duplication with vehicles already run by GSA and NASA. 

For you, that means federal IT buying is concentrating into fewer, mostly GSA-managed lanes. Knowing which lane your target agency uses is now a core capture skill. 

Here's an illustrative example, and a very common one. 

A small IT services firm spends eight months positioning for a $12 million defense support recompete. It networks with the program office, does its market research and puts a proposal team on standby. Three months before the expected release, the opportunity vanishes from the forecast. The agency has moved it to a multi-award BPA under GSA MAS. The firm holds no Schedule under the right Special Item Number (SIN), so it's disqualified before the race begins. 

Instead of walking away, the firm subcontracts to a MAS holder that has the vehicle but lacks its domain expertise. It captures about 40% of the work and uses that performance to pursue its own Schedule. 

The capture work wasn't wasted. What was missing was a vehicle strategy. (If you read our recompete guide, this is the step to add to your 12–18 month plan.) 

Myth 1: A GSA Schedule equals government sales.

A Schedule is a license to hunt, not a guarantee of meat. An idle Schedule is now a liability too. In March 2025, GSA announced it will let MAS contracts that miss the sales thresholds in clause I-FSS-639 expire. That threshold is $100,000 in the first 60 months and $125,000 in each 60-month option period, not the $25,000 many guides still quote. 

Our take: if no program office has told you, "We'd buy from you if you were on SIN X," build the relationship first and get the vehicle second. 

Myth 2: "We'll just win a spot on the next big GWAC."

On-ramps are rare, evaluations drag on for years, and scoring favors companies with prime federal past performance. CIO-SP4 is the cautionary tale: years of protests, then cancellation. Don't build your next five years around an on-ramp that may never open.

Myth 3: Subcontracting is for scraps

Primes often win big vehicles with plenty of capacity but gaps in niche skills such as AI model tuning, zero-trust architecture or cyber telemetry. That's your opening. Teaming can come together in weeks, while getting your own vehicle can take many months. You reach task orders now and build the past performance the next vehicle will demand. (More on that path in The Subcontractor to Prime Pipeline.) 

One rule to know: a GSA Contractor Team Arrangement is only for companies that each hold a MAS contract. If you don't hold one, your route in is a prime–subcontractor relationship. 

1. Isolate your market- In Market Intelligence, filter by target agency and your NAICS code (for example, 541512) or PSC. New to this step? Start with Federal Contracting Market Research: Find Your Buyer. 

2. Check the vehicle split- Open Vehicles Data to see how dollars break down across open-market awards, GSA MAS, GWACs, and agency IDIQs and BPAs. If most of the spend in your NAICS flows through vehicles, watching SAM.gov alone shows you only a fraction of the market. 

3. Map the prime holders- Drill into the dominant vehicle, review its top prime holders, and filter by socio-economic designation. Look for primes with capability gaps you fill or set-aside status you complement. 

4. Start the conversation- In Teaming Partnerships, search Partner Directory profiles with documented past performance and socio-economic designations. Then propose a subcontracting relationship, or a CTA if you both hold MAS contracts, before the next task-order cycle. 

Before you commit, run the opportunity through our 5-Point Qualification Framework. 

Don't spend 12 months waiting to get on a vehicle. Use GovCon360's Teaming Partnerships to search prime contract holders in your target agency today. Filter by capability, find the set-asides you're missing, and start the partnership conversation before the next task order drops.
