OASIS+
OASIS+ is GSA's flagship vehicle for complex professional services, replacing the original OASIS. It uses domain-based awards and includes separate pools for small business and socioeconomic categories.
- Managed by
- General Services Administration
- Ceiling
- Unrestricted plus multiple socioeconomic pools
- Scope
- Non-IT professional services: management, technical, logistics, R&D, intelligence services
- Period of performance
- 10-year ordering period
Key takeaways
- Vehicle access is a market position, not a contract — task orders are where revenue happens.
- Read the ordering guide before bidding a task order; format and evaluation rules differ from open-market RFPs.
- Fair-opportunity task orders move fast, often with 10 to 15 day response windows.
- Track on-ramp windows well in advance; they open rarely and close quickly.
How work is ordered
Agencies compete task orders among holders in the relevant domain and pool, using fair opportunity procedures. Task orders can be fixed-price, cost-reimbursement, time-and-materials, or labor-hour, which makes it unusually flexible for complex requirements.
Getting on the vehicle
OASIS+ was designed with open-season on-ramps, so new offers are accepted periodically rather than only at recompete. Qualification is based on meeting defined relevant-experience and past-performance criteria per domain, plus systems and accounting requirements for cost-type work.
Winning task orders
Pick your domains carefully — each requires qualifying experience, and over-reaching invites rejection. If you want cost-reimbursement task orders, get an approved accounting system in place early, because that single requirement excludes many otherwise capable competitors.
FAQ
Does OASIS+ cover IT?
No. It is scoped to non-IT professional services; IT belongs on vehicles such as MAS IT or CIO-SP4.
Can small businesses get on?
Yes, through dedicated small business and socioeconomic pools.
Are cost-type task orders allowed?
Yes, which is why an approved accounting system matters for holders pursuing them.
