The General Services Administration (GSA) has taken a significant step forward with the release of a new Request for Information (RFI) on June 17, 2025, marking the formal beginning of OASIS+ Phase II. With over $130 billion in projected spending across the programs being consolidated—OASIS, HCaTS, and BMO—this phase presents an unprecedented opportunity for both existing OASIS+ contract holders and new entrants to secure a place in a powerful, flexible acquisition vehicle.
As the federal government redefines its approach to procuring complex professional services, OASIS+ Phase II introduces five new domains that expand the scope of what’s possible under this Best-in-Class (BIC), no-ceiling contract. For contractors, this means new ways to compete, scale, and grow across the defense, civilian, and intelligence landscapes.
Why OASIS+ Phase II Matters Now
Phase II of OASIS+ isn’t just a continuation—it’s an evolution. The GSA’s approach to domain-based procurement empowers ordering contracting officers (OCOs) to match agency needs to qualified vendors with greater accuracy and flexibility. With no ceiling on total contract value and no cap on the number of awards, Phase II opens doors for:
- Firms that missed the original solicitation deadline
- Current OASIS+ awardees seeking to add new domain qualifications
- Specialty providers ready to compete in new domain areas with focused capabilities
By aligning the contract vehicle with evolving federal requirements, OASIS+ Phase II allows GSA to adaptively fill gaps in service areas and accommodate emerging mission needs without restarting a full acquisition cycle.
Understanding the OASIS+ Ecosystem
The OASIS+ program represents a dramatic departure from legacy models that often placed caps on contractor counts or funding obligations. With no limit on the number of contract holders, contractors have a higher probability of entry—provided they meet qualification criteria.
Equally important is the structure of the vehicle. By organizing awards into “domains” rather than broad service categories, GSA has enabled a more flexible and targeted contracting approach. Each domain is built around specific NAICS codes and service competencies, allowing for:
- More accurate matching of contractor skills to agency needs
- Clearer scoring and evaluation metrics during proposal assessment
- Reduced duplication across existing contract vehicles
This structure also simplifies future expansions. New domains can be introduced through additional On-Ramp phases without disrupting the current ecosystem—ensuring that OASIS+ remains agile and responsive.
Overview of the Five New Domains
The Phase II RFI outlines five proposed domains. Each domain contains its own set of NAICS codes, functional descriptions, and performance requirements. Here’s a breakdown of what they include:
1. Business Administration
This domain covers general administrative, secretarial, document management, and language services. It supports agencies in improving operational efficiency through support staff augmentation, data management, and multilingual support.
2. Financial Services
This domain includes accounting, financial advisory, grant management, and risk assessment services. Contractors offering deep expertise in government financial regulations and compliance will find significant opportunities here.
3. Human Capital
Derived from and replacing elements of HCaTS, this domain focuses on recruitment, training, workforce development, and organizational transformation. This is critical for agencies modernizing their talent acquisition and retention strategies.
4. Marketing and Public Relations
This domain encompasses strategic communications, media management, branding, social media, and event support. With the increasing need for digital outreach, this domain could see rapid expansion.
5. Social Services
A unique addition, this domain addresses support services like vocational rehabilitation, behavioral health, youth and family programs, and community integration. It highlights the government’s expanding focus on holistic support services.
Value Propositions and Program Scale
The original OASIS, HCaTS, and BMO programs collectively managed over $130 billion in obligations. OASIS+ Phase II is not only expected to match but exceed that value over its 10-year performance period. Importantly, as detailed in Section B of the solicitation:
- There is no maximum dollar ceiling for the master contract or any individual task order.
- Unlimited task orders may be issued over the life of the contract.
- OCOs will set individual ceilings at the task order level, per their agency’s requirements.
The result is a high-trust, high-opportunity environment where qualified vendors can pursue federal work without being limited by traditional contract ceilings or vendor caps.
Opportunities for Two Key Contractor Profiles
Whether you’re new to OASIS+ or already hold a position, OASIS+ Phase II offers strategic entry points.
For Non-Awardees from Round One
You now have a second chance to get on the vehicle. With the same self-scoring structure and opportunity to submit documentation for qualifications, you can:
- Enter the federal market with a Best-in-Class contract
- Gain a competitive edge with a long-term contracting vehicle
- Position your firm for major IDIQ/MAC opportunities

For Existing OASIS+ Contract Holders
Already awarded one or more domains? Phase II allows you to:
- Expand into new mission-aligned domains
- Grow revenue with cross-domain eligibility
- Leverage existing past performance and qualifications to qualify for new categories
The self-scoring structure still allows for maximum transparency and strategic proposal planning.
Strategic Considerations for Contractors
1. Alignment of Capabilities
Before responding to the RFI or future solicitation, conduct a gap analysis:
- Which new domains align with your technical offerings?
- What past performance examples meet the domain-specific NAICS requirements?
2. Documentation and Readiness
Prepare early:
- Update project documentation with client references
- Align certifications (e.g., ISO, CMMI, CPA credentials) with the scoring model
- Begin teaming discussions for domains where you lack direct past performance
3. Monitoring for Final RFP Release
Based on historical trends from OASIS+ Phase I, GSA may provide:
- Webinars and Q&A sessions
- Draft RFPs for review
- Proposal templates and scoring guides

Contractors should also subscribe to Interact.GSA.gov and actively track updates on SAM.gov to stay ahead.
Preparing for the Self-Scoring Model
The self-scoring proposal structure will likely remain in effect. Key point categories may include:
- Relevant past performance in the selected domain
- Corporate certifications and clearances
- Teaming arrangements and subcontractor qualifications
- System readiness and operational maturity
Agencies value low risk. The self-scoring system is designed to help the government identify capable vendors who can perform reliably. Contractors who can organize, document, and validate their capabilities early will have a significant advantage.
Implications of the No-Ceiling, Open-On-Ramp Structure
The FAR Class deviation supporting OASIS+ Phase II removes the traditional ceiling limits and allows for continuous onboarding of contractors. This ensures:
- No artificial barriers to entry for qualified firms
- Agencies always have access to the right mix of suppliers
- Contractors can submit proposals when strategically ready, rather than rushing to meet a single submission window
This dynamic model reflects the GSA’s recognition that innovation and capability development don’t happen on fixed timelines.
Moreover, by maintaining an always-on approach to onboarding, OASIS+ ensures that qualified small businesses and new market entrants can access critical opportunities when they are truly ready, not just when the federal calendar opens a narrow window.
The Road Ahead: What Contractors Should Do Now
- Read the RFI Carefully: Understand each domain’s scope and corresponding NAICS codes.
- Evaluate Your Positioning: Identify where you qualify strongly and where you might need teaming or investment.
- Start Assembling Proposal Assets: Align resumes, project summaries, and system documentation.
- Subscribe for Updates: Monitor the OASIS+ Interact page, SAM.gov, and GSA webinars.
- Map Out a Multi-Domain Strategy: Even if you target one domain now, plan to grow into others over time.
- Engage Early with Partners: Consider building early teaming arrangements with firms strong in complementary domains. Sharing points on a proposal could boost your score and strengthen your win strategy.
Conclusion: A Gateway to Federal Growth
OASIS+ Phase II reflects the most progressive elements of GSA’s acquisition philosophy—flexible, scalable, inclusive, and strategically aligned with evolving agency needs. It isn’t just a new contract phase; it’s a new era of federal contracting.
Whether you’re an emerging small business or an established federal integrator, the addition of five new domains—paired with unlimited on-ramping and a no-ceiling structure—offers unparalleled growth potential. Position your company now, and you’ll be ready to compete not just for awards, but for leadership in your sector.
