GSA Schedule vs. GWAC: Which Contract Vehicle Should You Pursue?
GSA Schedule and GWACs both simplify the buying process for agencies, but they serve different buyers and require different qualifying factors. Here is how to choose the right one for your company.
Marcus Webb
A GSA Schedule (officially the Multiple Award Schedule) is a pre-competed, open-ended contract that any agency can use to buy commercial products and services without a full competitive bid. A GWAC (Government-Wide Acquisition Contract) is a separate category — also pre-competed, but awarded to a defined pool of vendors for a specific scope, usually IT. You need both in a mature federal contracting business, but you should not pursue them in the same order or on the same timeline.
What a GSA Schedule actually is — and what it is not
The GSA Multiple Award Schedule is a long-term indefinite delivery/indefinite quantity (IDIQ) contract with a base period of five years and three five-year option periods. Being "on Schedule" means GSA has already approved your labor rates, product prices, and company profile, so agencies can buy from you under a simplified ordering process called a Task Order rather than a full solicitation.
- Any federal civilian or DoD agency can buy off Schedule — there is no locked-in list of authorized users
- Schedule does not guarantee any work — you must still market, position, and win task orders competitively
- GSA Advantage! and eBuy are two platforms where agencies post and agencies respond to Schedule-based requirements
- Minimum sales threshold: $25,000 in Schedule sales within the first two years — or GSA can cancel your contract
- Prices must be fair and reasonable; GSA will compare your rates to what you charge commercial customers
- The Most Favored Customer (MFC) disclosure means you must report your best commercial pricing during proposal and updates
What a GWAC is and who runs the main ones
A GWAC is a multiple-award IDIQ reserved for IT acquisitions and operated by a single agency on behalf of the entire government. Unlike a Schedule, GWAC on-ramps happen at defined intervals — you cannot apply whenever you want. The four most active GWACs in IT are run by different agencies, each with different scopes and ordering volumes.
- Alliant 3 (GSA): large unrestricted IT IDIQ, expected $50B ceiling, full and open competition
- SEWP VI (NASA): hardware, software, and IT solutions; two pools — products and solutions
- CIO-SP4 (NIH): health IT focus, small business set-asides, and an unrestricted pool
- OASIS+ (GSA): professional services including program management, logistics, and research; NOT purely IT
- Each GWAC has a different minimum qualifications threshold — past performance scoring is often decisive
- Being on a GWAC means agencies can issue task orders directly to your pool without a new full competition
Side-by-side: Schedule vs. GWAC
The core difference is access. A Schedule is a standing offer any agency can use at any time. A GWAC puts you in a defined pool that agencies must specifically choose to use — but once they do, the competition is only within that pool, which is often smaller and more predictable.
- Schedule: open continuous enrollment, any agency, commercial rates negotiated upfront
- GWAC: periodic on-ramps, defined scope, task orders competed within the awarded pool
- Schedule: typically takes 6–12 months from application to award; GWACs can take 18–36 months
- Schedule: no ceiling per vendor; GWACs have a vehicle-wide ceiling shared among all awardees
- Schedule: better for commercial services and products already sold to non-federal customers
- GWAC: better for pure-play IT services with demonstrated federal past performance
- Schedule renewal: annual modifications required; GWAC renewal: usually tied to option periods
Which one to pursue first
Most companies start with the GSA Schedule because enrollment is continuous — you do not have to wait for a solicitation window. The Schedule also has lower past performance thresholds for newer vendors. GWACs require competitive bids scored on past performance, past revenue, and staffing plans, which means they favor companies with two or more years of federal revenue behind them.
- Year 0–2 in GovCon: focus on SAM.gov registration, a few direct awards, and building past performance
- Year 2–4: apply for a GSA Schedule in your primary NAICS; this opens civilian and DoD buyers
- Year 3+: watch GWAC on-ramp solicitations that match your scope; begin assembling a teaming strategy
- Small businesses: SEWP VI and CIO-SP4 both have small business set-aside pools — start with those
- If you are IT-only with strong past performance, Alliant 3 is the long-term goal for volume
- OASIS+ covers professional services beyond IT — worth pursuing if you do program management, logistics, or research
Common mistakes when pursuing a GSA Schedule
The GSA Schedule application process has strict documentation requirements. Rejections and delays are most often caused by preventable gaps in the submission package.
- Submitting commercial invoices without a clear narrative explaining what services they represent
- Pricing that does not match your commercial pricelist — GSA checks for discounting inconsistencies
- Missing or incomplete Basis of Award (BOA) documentation — this is the most common rejection reason
- Not calculating your Industrial Funding Fee (IFF) correctly: currently 0.75% of all Schedule sales
- Letting your SAM.gov registration lapse while the Schedule application is in review
- Applying for SINs (Special Item Numbers) you cannot actually deliver — start narrow, expand later
How to track open GWAC on-ramps
GWAC solicitations are posted to SAM.gov like any other procurement. The challenge is that they close on fixed dates and are intensely competitive. You need to be watching months in advance.
- Set a SAM.gov saved search for "GWAC" or the specific vehicle name (e.g., "Alliant 3", "SEWP VI")
- Subscribe to GSA and NIH procurement newsletters — they announce upcoming on-ramps 6–12 months out
- Identify teaming partners early: many GWAC proposals are won by companies that team rather than bid solo
- Review past performance requirements before the solicitation drops — build or acquire the PPQs you will need
- Attend industry days: GWAC program offices actively use them to signal what evaluators will weight heavily
- Use GovPillar to track award history on the current vehicle iteration to size the opportunity correctly
Frequently Asked Questions
Can a small business get on a GSA Schedule?
Yes. Most GSA Schedule SINs are open to small businesses, and there is no minimum revenue requirement at the time of application. You do need two or three commercial contracts or invoices to demonstrate you can deliver the services at the rates you propose.
How long does it take to get awarded a GSA Schedule?
Typically 6–12 months from completed submission. Incomplete offers are returned and add months to the clock. Companies that submit a clean, complete package with all required attachments consistently see faster reviews.
What is the difference between a GWAC and a BPA?
A GWAC is a separate contract vehicle operated by a federal agency. A Blanket Purchase Agreement (BPA) is an ordering agreement set up against an existing contract like a GSA Schedule. BPAs are set up by individual buying offices; GWACs are established by a central acquisition authority for government-wide use.
Is being on GSA Schedule worth it for a small business?
It depends on your market. If your customers are civilian agencies buying commercial IT, consulting, or facilities services, yes — Schedule simplifies their ordering process and removes procurement barriers. If your primary customers are DoD programs buying highly customized technical work, Schedule may be less relevant than pursuing a GWAC or competing on full-and-open solicitations.
What is Alliant 3?
Alliant 3 is the successor to Alliant 2, a large IT GWAC run by GSA with an expected ceiling around $50 billion. It is unrestricted (not set-aside) and targets complex IT solutions across the entire federal government. An Alliant 3 small business version is expected to run alongside it.
