August 19, 2025 – GSA Releases Q&A on OASIS+ Phase II RFI:
The GSA Contracting Office published a Q&A from the OASIS+ Phase II RFI on August 19, 2025, via GSA Interact
Key takeaways:
- GSA is still evaluating market research findings before deciding on next steps.
- Options under consideration include:
- Adding new domains (in part or in full).
- On-ramping new contractors to existing domains.

- Formal updates will be shared once decisions and schedules are finalized.
On June 17, 2025, the General Services Administration (GSA) released a Request for Information (RFI) to kick off OASIS+ Phase II, signaling plans to expand the OASIS+ contract with five new service domains.
OASIS+ (One Acquisition Solution for Integrated Services Plus) is GSA’s next-generation, best-in-class (BIC) professional services contract vehicle, notable for its no contract ceiling, 10-year ordering period, and multiple award pools for different business sizes.
In Phase II, GSA is seeking industry input on adding new domains – Business Administration, Financial Services, Human Capital, Marketing & Public Relations, and Social Services – to broaden the scope of OASIS+.
This development is strategically important for government contractors, as it opens new avenues to compete for federal work under a flexible and expansive contracting program. This blog explores what the new RFI is all about.
New Domains Introduced in OASIS+ Phase II
GSA confirmed that all existing OASIS+ domains will be retained in Phase II, ensuring continuity for offerors preparing to submit under the expanded structure. Phase II introduces five additional service domains, bringing the total to 13 domains across the contract vehicle. These new domains reflect federal demand trends identified through market research, spend analysis, and industry feedback. Below is a summary of each new domain and what it encompasses:
Business Administration:
General administrative support services, including clerical and secretarial support, record/document management, and related office support (even covering areas like translation and language services). This domain is aimed at helping agencies improve operational efficiency through administrative staff augmentation and data management support.
Financial Services:
Financial management and advisory services such as accounting, auditing, budget support, grant management, and risk assessment. Contractors with expertise in federal financial regulations, compliance, and fiscal analysis will find opportunities in this domain to assist agencies with financial oversight and program management.
Human Capital:
Human resources and workforce solutions, building on the legacy HCaTS contract scope. This domain involves services like recruitment and staffing, training and development, talent management, and organizational development. It reflects the government’s need to modernize talent acquisition, improve workforce training, and manage organizational change in federal agencies.
Marketing & Public Relations:
Strategic communications and outreach services, including branding, media relations, marketing campaigns, public affairs, social media management, and event planning support. With a growing emphasis on digital engagement and public communication, this domain enables agencies to obtain expert help in communicating their message and managing stakeholder relations.
Social Services:
A broad domain covering social and community support services. This can include vocational rehabilitation programs, counseling and behavioral health services, youth and family services, community outreach, and other social assistance efforts. The inclusion of Social Services as a domain highlights an expanding federal focus on human services and programs that support citizens’ well-being.
Each of these new domains will have specific NAICS codes and qualification criteria associated with them. By defining domains in functional groupings, GSA can more precisely scope the contracts and match agency needs with industry capabilities.
Key RFI Details: Dates and How to Respond
GSA’s Office of Professional Services and Human Capital Categories (PSHC) issued the Phase II RFI via SAM.gov on June 17, 2025. The RFI is open for three weeks, with industry feedback due by 5:00 PM (ET) on July 8, 2025. Importantly, GSA is collecting responses through an online questionnaire on SAM.gov, rather than a traditional narrative response. Contractors interested in providing input must submit the RFI questionnaire by the deadline, which is estimated to take about 30 minutes to complete. The questionnaire asks respondents about their business (e.g., small business status, socioeconomic categories, relevant contract vehicles held) and seeks comments on the proposed five new domains, including any overlaps or interdependencies with the existing domains. GSA does not require answers to every question – firms can focus on the domains most relevant to them.
Submission instructions:
To respond, vendors should visit the SAM.gov posting for “OASIS Plus Phase II RFI” and follow the link to the GSA Phase II RFI questionnaire. Ensure you have your UEI (Unique Entity ID) and basic company info on hand, as well as any feedback on domain scopes or evaluation factors. All feedback must be submitted via the official questionnaire form; emailed or paper responses are not accepted. Contractors may also submit questions to GSA (a separate “questions intake form” was provided on SAM.gov) if any clarification is needed during the RFI open period.
Key dates to note:
- RFI Release: June 17, 2025
- RFI Response Deadline: July 8, 2025, 5:00 PM Eastern Time
- Method of Response: Complete the GSA online questionnaire
GSA will use the RFI responses to inform the development of Phase II – including refining domain definitions, requirements, and evaluation criteria for the eventual solicitation. This is a critical chance for industry to shape the contract’s direction before the official Phase II RFP is drafted.
GSA has also shared its preliminary forecast for upcoming Phase II milestones. According to the agency’s planning notice, Draft Scorecards are expected to be released on December 16, 2025, followed by the Final Phase II Solicitation on or about January 12, 2026. While these dates remain subject to change, they provide contractors with an early window into when evaluation details and submission requirements may become available.
Why OASIS+ Phase II Matters to Government Contractors
GSA’s OASIS+ Phase II is more than a routine update—it’s a strategic expansion that brings long-term value and broader access to professional services contractors. Here’s why it matters:
- No Ceiling, Unlimited Awards: Like Phase I, Phase II maintains an unlimited contract value and award structure. This means greater opportunity without a cap on spending or vendor participation, aligning with GSA’s push for flexibility and scalability.
- Expanded Service Coverage: The addition of five new domains (e.g., Human Capital, Financial Services) broadens OASIS+ to support more agency missions. The domain-based approach enables integrated solutions, allowing for varied contract types and multidisciplinary needs.
- Open On-Ramping: Unlike legacy contracts, OASIS+ offers rolling on-ramp opportunities. Phase II is not just for new domains—it’s also a second chance for firms that missed the initial award window or want to expand their qualifications.
- 10-Year Contract Stability: With a five-year base and a five-year option, OASIS+ is a stable platform for consistent task order opportunities across a decade.
- Strategic Fit for BIC Goals: As a Best-in-Class (BIC) contract vehicle, OASIS+ consolidates former programs like OASIS, HCaTS, and BMO. For contractors, this means fewer silos and more centralized access to high-value contracts under one umbrella.
What Contractors Should Do Now:
Review your service offerings against the new domains, assess gaps, and prepare to respond when the formal Phase II solicitation is issued—potentially later in FY 2025. GSA’s emphasis on agility and inclusivity means opportunity remains open, but preparedness will be key.
GSA’s Strategic Direction and What It Means for Contractors
OASIS+ Phase II continues GSA’s broader strategy of consolidating professional services contracts and advancing category management through Best-in-Class (BIC) solutions. By merging legacy vehicles like OASIS, HCaTS, and BMO and introducing an expanded set of domains, GSA aims to streamline acquisitions, reduce overlap, and better align industry capabilities with federal mission needs.
Phase II also reinforces GSA’s commitment to continuous open solicitations, enabling qualified contractors to enter the vehicle on a rolling basis rather than waiting for multi-year recompetes. The refinements in this phase are informed by:
- Market Research: Identifying emerging capability gaps and government-wide demand signals.
- Spend Analysis: Understanding where federal dollars are increasing across mission support areas.
- Industry RFI Feedback: Developing clearer, more functional domains based on input from both small and large businesses.
For contractors, this shift means:
- One Contract, Expanded Avenues: A broader set of domains allows firms to offer business, HR, financial, marketing, operational, and social service capabilities under one integrated BIC vehicle.
- Improved Access for Small and Diverse Businesses: Phase II maintains six small business award pools (SB, WOSB, SDVOSB, etc.), reinforcing GSA’s goal of increasing diverse participation.
- A Living Contract Model: Continuous on-ramps mean new entrants can join regularly, while incumbents must maintain competitiveness as evaluation factors evolve.
- Greater Visibility Through BIC Emphasis: With agencies pushed to prioritize BIC solutions, earning a spot on OASIS+ can significantly enhance contractor marketability.
As GSA continues moving toward a smarter, more centralized procurement model, maintaining readiness for Phase II scorecards, new domains, and future on-ramps positions contractors to stay aligned with federal acquisition priorities.
