Good news for Professional Services contractors--GSA is looking to add new domains to their OASIS+ contracting vehicle supporting their Office of Professional Services and Human Capital Categories (PSHC). On June 17, 2025, GSA released a Request for Information (RFI) to open Phase II of the vehicle and develop evaluation criteria for five new domains. OASIS+ provides government buyers with non-IT services and includes small business set-asides. Since the RFI responses are due soon on July 8, let's review what OASIS+ is and how your business may be able to benefit from this vehicle.
What is GSA’s OASIS +?
OASIS +, or One Acquisition Solution for Integrated Services (OASIS)+ is a Best-In-Class (BIC) Indefinite Delivery Indefinite Quantity (IDIQ) contract for non-IT professional services. This means it's a high performing vehicle that is set up to provide an indefinite quantity of services for a fixed period of performance.
The primary purpose of OASIS + is to give government agencies easy and efficient access to innovative services from highly qualified businesses. OASIS+ Phase I awardees for both the small business pools and the unrestricted pools were announced in late 2024. OASIS+ is a unique small business contract because it includes pools for 8(a), HUBZone, Service-Disabled Veteran-Owned, and Women-Owned small businesses.
Scope of OASIS+
The contract vehicle’s scope is organized by Domains which make it easier for government agencies, because when they are ready to issue a task order solicitation, they will select the contract family first, and then the Domain that meets their needs. Each Domain will have a list of North American Industry Classification (NAICS) Codes Codes to choose from.
For Small Business contracts, the primary NAICS assigned will be based on the largest size standard. For Unrestricted contracts, the primary NAICS assigned will be based on the smallest size standard.
Domains refer to the functional groupings of related services spanning multiple NAICS. GSA will add new Domains based off data information assessments and needs, but the currently identified Domains are listed below.
Multiple Domains will be assigned to this contract vehicle and each Domain is limited to the NAICS Codes specifically outlined.
The current Domains for both Unrestricted and Small Businesses are:
- Management & Advisory
- Technical & Engineering
- Research & Development
- Intelligence Services
- Environmental
- Facilities
- Logistics
The final Domain, Enterprise Solutions, is for the Unrestricted pool only. In the recent RFI, GSA wants to add five additional domains, which we'll discuss below.
RFI to Add Additional Domains to OASIS+
About 6 months after all the awardees were announced for Phase I, GSA wants to learn more about the possibility of adding five additional domains in Phase II. In their RFI, which is due on July 8, 2025, GSA seeks industry feedback on the following domains:
- Business Administration
- Financial Services
- Human Capital
- Marketing and Public Relations
- Social Services
Let's briefly cover each domain and what NAICS Codes are associated with them.
1. Business Administration
This section is for administrative and business management services. This includes language services, document management, administrative support, and data services. The NAICS Codes are anticipated to be:
2. Human Capital
This domain includes training and development services, human capital strategy services, and organizational performance improvement. The anticipated NAICS Codes are:
3. Financial Services
This area includes the support of financial objectives such as accounting, budgeting, financial advising, loan servicing, asset management services, and complementary financial services. The NACIS Codes are:
4. Marketing and Public Relations
This functional area includes marketing & public relations services that span advertising, marketing, and production and media services. The relevant NAICS Codes include:
5. Social Services
This domain includes social services requirements that benefit the community and society. The proposed NAICS Codes are:
Trump Administration Increases Focus on Best-In-Class Contracts Like OASIS+
In the Executive Order on Consolidating Procurement, the Trump Administration plans to transition the acquisition of common goods and services to GSA, as well as put a stronger emphasis on Governmentwide Acquisition Contracts (GWACs) and other Best-In-Class (BIC) like OASIS+. These vehicles are high performing and are built for efficiency and cost reduction, so the administration wants to encourage federal agencies to use them for their products and services needs. GSA also plans to move certain vehicles over that aren't already managed by them, including NASA's SEWP V & VI and the National Institute of Health's (NIH) CIO-SP3 vehicle.
This is good news for contractors already under GSA's OASIS+ and those looking to on-ramp soon. If you are looking to get involved with OASIS+, we suggest you respond to the RFI to get your foot in the door, and potentially shape the scope of the domains GSA plans to add.
