The GSA Multiple Award Schedule generates over $50 billion in annual spending across more than 6,000 federal buying entities — making it the most widely used contract vehicle in the federal government. However, Schedule usage varies dramatically by agency, mission, and procurement category. Some agencies use it for 80% of their routine purchases; others use it for less than 20%. Understanding your target agency's actual Schedule usage pattern is more important than knowing the government-wide statistics.
How much does the federal government buy through the GSA Schedule each year?
The GSA Schedule program generates approximately $50 to $55 billion in annual spending across all categories. IT products and services account for roughly $25 billion; professional services account for approximately $10 billion; facilities and maintenance account for approximately $5 billion; and the remaining $10 to $15 billion covers all other categories. This represents roughly 7 to 10% of total discretionary federal procurement spending.
| Category | Approximate Annual Schedule Spend | Primary Buying Agencies |
|---|---|---|
| IT Products and Services | $25 billion | DOD, DHS, HHS, Treasury, VA |
| Professional Services | $10 billion | DOD, DHS, State, DOE, DOI |
| Facilities and Maintenance | $5 billion | GSA, DOD, VA, DHS |
| Office Products and Furniture | $3 billion | All civilian agencies |
| Medical and Health | $4 billion | VA, HHS, DOD medical |
| Other Categories | $8 – $10 billion | Distributed across all agencies |
Which agencies use the GSA Schedule most heavily?
The Department of Defense is the largest single user of the GSA Schedule, followed by the Department of Homeland Security, the Department of Veterans Affairs, and the Department of Health and Human Services. These four agencies collectively account for over 60% of annual Schedule spending. For contractors targeting these agencies, the Schedule is an essential vehicle — not a secondary option.
When I was a Contracting Specialist at GSA, the buying patterns I observed across the government were consistent: civilian agencies with large, recurring IT and professional services needs used the Schedule constantly. Agencies with highly specialized or classified requirements used it sparingly. The Schedule's simplified ordering mechanism under FAR 8.4 was most attractive to agencies that needed to move quickly on commercial service needs — which is most civilian agencies most of the time.
- High Schedule usage agencies:
- Department of Defense (DOD) — $15+ billion annually
- Department of Veterans Affairs (VA) — $8+ billion annually
- Department of Homeland Security (DHS) — $5+ billion annually
- Department of Health and Human Services (HHS) — $4+ billion annually
- Department of the Treasury — $2+ billion annually
- Moderate Schedule usage agencies:
- Department of State, Department of Education, EPA, USDA, DOE, DOI
- Lower Schedule usage agencies (classified or specialized missions):
- Intelligence community agencies, certain defense research organizations
Does Schedule usage vary by service category within the same agency?
Yes, significantly. An agency that heavily uses the Schedule for IT professional services may rarely use it for construction, training, or specialized research services. The vehicle that an agency uses depends on the type of requirement — not just the agency name. Check USASpending.gov for Schedule-specific orders in your NAICS code at each target agency before assuming the Schedule is the right vehicle for your specific service type.
As a Contracting Officer, my choice of procurement vehicle was driven by the specific requirement, not agency policy. For IT development support, the Schedule was almost always my first consideration. For construction projects, I used agency-specific IDIQ vehicles with construction-specific terms and bonding requirements. For research and development, I used FAR Part 15 procedures or Other Transaction Authority. One agency, multiple vehicles, different rules for each.
How do I find out how much my target agency spends through the Schedule?
USASpending.gov shows all federal contract awards, including Schedule-based delivery orders and BPA calls. Filter by your target agency, your NAICS code, and award type (delivery orders) to see your target agency's Schedule spending in your category. This data is updated regularly and is the most reliable source for agency-specific procurement pattern analysis.
- Go to usaspending.gov
- Click "Award Search"
- Filter by Awarding Agency (your target agency)
- Filter by NAICS Code (your service category)
- Filter by Award Type: "Delivery Orders" and "BPA Calls" (these are Schedule orders)
- Sort by Total Obligated Amount to see the biggest Schedule buyers in your category
- Review the top 10 award recipients — these are your competitors and market benchmark
Are there agencies where the Schedule is essentially required?
Some agencies have internal policies that direct buyers to prefer Schedule purchases for commercial item requirements below certain thresholds. VA, DHS, and several other civilian agencies have issued guidance encouraging Schedule use for IT and professional services. No agency is legally required to use the Schedule — FAR 8.004 describes it as one of several preferred sources — but internal agency culture and policy can create de facto requirements at specific agencies.
Across our 70+ proven GSA contract awards, contractors who target agencies with strong Schedule buying cultures — VA, DHS, HHS — generate significantly more revenue from their Schedule in years one and two than contractors targeting agencies with lower Schedule usage rates. The vehicle does more work for you when the buying culture already favors it.

Frequently Asked Questions
Do local and state governments buy through the GSA Schedule?
Yes, under limited circumstances. GSA's Cooperative Purchasing Program allows state, local, tribal, and territorial governments to purchase certain IT products and services (SIN 54151S and related IT SINs) and law enforcement equipment through the Schedule. This authority does not extend to all Schedule categories. Confirm whether your SIN category is eligible for cooperative purchasing before marketing the Schedule to state and local buyers.
Why do some agencies have their own acquisition vehicles instead of using the GSA Schedule?
Agency-specific vehicles are established when the Schedule cannot accommodate specific mission requirements — classified ordering, unique technical specifications, agency-specific terms and conditions, or domain complexity that exceeds the Schedule's commercial item framework. Examples include SEWP (NASA), NITAAC (NIH), CIO-SP4 (NIH), and various DOD-specific vehicles. These vehicles coexist with the Schedule rather than replacing it.
What is the Schedule's market share in federal IT spending?
The GSA Schedule captures approximately 15 to 20% of total federal IT spending annually. Agency-specific GWACs (SEWP, NITAAC), DOD IT vehicles, and open market competition account for the remainder. Within civilian agencies, the Schedule's IT market share is higher — often 25 to 35% — because civilian agencies rely more heavily on commercial item vehicles than DOD's specialized IT procurement ecosystem.
Has Schedule spending increased or decreased in recent years?
Schedule spending has been relatively stable over the last several years, with gradual growth in IT and professional services categories offset by procurement consolidation trends under GSA's OneGov initiative and executive orders emphasizing competitive pricing. The 2020 MAS consolidation reduced the number of Schedule vehicles from many legacy schedules to one, but total spending volume remained comparable to pre-consolidation levels.
Can I see my specific competitors' Schedule order history at my target agency?
Yes. USASpending.gov shows the contractor name, award amount, agency, and order description for every Schedule delivery order. You can search your competitors by name or filter by NAICS code at a specific agency to see exactly who is winning Schedule orders in your category, what the contract values are, and how frequently they are receiving orders. This is the most valuable competitive intelligence tool available in federal contracting.
