Short Answer
Pursue GSA MAS first if you sell products, have smaller projects, or want to be on contract with the most agencies soonest. Pursue OASIS+ first if you provide professional services in one of its 13 domains and have larger projects that can clear a domain's scorecard threshold. Many services companies eventually hold both.
"Should we go after OASIS+ or the GSA Schedule?" is one of the most common questions we get from services companies. Both are GSA contracts, both are governmentwide, and both are open for new offers right now. But they're built for different things, qualified differently, and used differently by agencies.
The short version: they're not really competitors. Many of our clients hold both. The question is which one to pursue first.
The key differences
| GSA MAS | OASIS+ | |
|---|---|---|
| What you sell | Products and services | Professional services across 13 domains (products and IT only in support of those services) |
| How you qualify | Offer reviewed and negotiated by a GSA contracting officer | Self-scored 50-credit scorecard per domain, verified by GSA |
| What's evaluated | Corporate experience, past performance, project experience and pricing, by SIN | Qualifying projects, federal experience, systems and certifications, by domain |
| Project size needed | No scorecard minimums, though projects must support each SIN | Qualifying projects must meet each domain's minimum average annual value |
| Pricing | Negotiated prices or rates on the contract | Evaluated at the master contract level; each task order must be priced fair and reasonable |
| Order types | Firm-fixed-price, time-and-materials, labor-hour | Any type, including cost-reimbursement and hybrids |
| Fee | Industrial Funding Fee, currently 0.75% | Contract access fee of 0.15% on task orders |
| Open for offers? | Year-round | Continuously open since January 2026 |
When GSA MAS should come first
MAS usually makes sense as the first vehicle if:
- You sell products, or products and services together. OASIS+ is a services vehicle.
- Your projects are smaller. MAS doesn't use scorecard minimums, while OASIS+ qualifying projects must clear each domain's minimum average annual value, which runs from about $250,000 to $1 million for small business pools.
- You want broad, simple buying access. Agencies can buy directly from MAS contracts for many straightforward requirements.
- You're building a federal track record. A MAS contract can help you win the task orders that later become OASIS+ qualifying projects and federal experience credits.
When OASIS+ should come first
OASIS+ is often the better first step if:
- You provide professional services in one of the 13 domains, like technical and engineering, management and advisory, logistics or facilities support.
- You have larger projects that clear the domain minimums and add up to a strong score.
- Your customers need complex or cost-type work. OASIS+ task orders can be cost-reimbursement, which MAS orders can't.
- You're targeting larger, integrated requirements that agencies route to OASIS+ rather than the Schedule.
Why many companies end up with both
The two vehicles complement each other. MAS covers products and simpler services buys. OASIS+ covers complex, integrated services requirements. Holding both lets you respond to a requirement however the agency chooses to buy it.
The order also compounds. Work won on one vehicle becomes experience for the other: MAS task orders can later support OASIS+ qualifying projects or federal experience credits, and OASIS+ work strengthens your MAS relevant project experience.
How we help companies decide
When a client asks which to pursue first, we look at three things:
- What they sell. Products point to MAS. Professional services can go either way.
- Their projects. We check whether their best projects clear OASIS+ domain minimums and model a score. If they can clear the threshold with a cushion, OASIS+ is a real option now.
- Their customers. How do the agencies they want to work with actually buy? That often decides it.
If OASIS+ is within reach, we usually recommend pursuing it. If the scoring is borderline, MAS first, with a plan to build toward OASIS+, is often the faster path to revenue.

Frequently Asked Questions
Can I hold both OASIS+ and GSA MAS?
Yes. They're separate contracts, and many services companies hold both. MAS often works as the entry point, while OASIS+ opens larger, more complex requirements.
Which is easier to get?
It depends on your projects. MAS doesn't use a scorecard, so smaller companies with relevant experience can often qualify. OASIS+ requires projects above a minimum average annual value and a domain score above the threshold, which favors companies with larger past projects.
Can agencies use cost-reimbursement contracts through MAS?
No. MAS orders are firm-fixed-price, time-and-materials or labor-hour. OASIS+ task orders can be any contract type, including cost-reimbursement, which makes OASIS+ a better fit for certain complex requirements.
What fees do they charge?
MAS carries an Industrial Funding Fee, currently 0.75% unless the solicitation states otherwise. OASIS+ carries a contract access fee of 0.15% on invoiced task order amounts.
Are both open for new offers?
Yes. The MAS solicitation is open year-round, and all six OASIS+ solicitations have been continuously open since January 2026.
