GSA built OASIS+ to consolidate the entire non-IT professional services market into one vehicle. That means billions shifting from agency-specific IDIQs onto a single platform with 13 domains, rolling on-ramps, and task orders flowing through eBuy. For contractors, it's access to more work through fewer vehicles. For your capture team, it's knowing which pools you qualify for and how to score your own proposal before GSA does.

TL;DR

• OASIS+ is GSA's consolidated contract vehicle for federal non-IT services, now expanded to 13 domains

• Phase II opened continuous on-ramps with no submission deadlines across six pools

• Agencies post all task orders through GSA eBuy with fair opportunity rules for qualified contractors

• Self-scoring evaluations require qualifying projects at $1M (unrestricted) or $500K (small business)

• GovDash accelerates OASIS+ proposals with capability mapping, compliance matrices, and AI drafting

What Is OASIS+

OASIS+ is GSA's governmentwide indefinite delivery, indefinite quantity (IDIQ) contract suite for non-IT professional services. Federal agencies use it to procure services like engineering, logistics, financial management, and program support across multiple domains.

GSA launched OASIS+ to consolidate legacy contract vehicles including the original OASIS contract, HCaTS (Human Capital and Training Solutions), and BMO (Blanket Purchase Agreements for Mission-Oriented Business Integrated Services). This merger streamlines procurement for agencies and expands contractor access to federal work through one vehicle.

The contract serves the entire federal government, with billions in projected value over its ordering period.

OASIS+ Phase II Expansion and 13 Service Domains

On December 4, 2025, GSA announced a major Phase II expansion of OASIS+, opening continuous on-ramps and adding five new service domains across all six contract pools. The expansion brings the total to 13 domains, broadening the scope of work agencies can pursue.

The original eight domains (Engineering, Environmental, Logistics, Management and Advisory, Program Support, Scientific, Technical and Analytical, and Transportation) are now joined by Business Administration, Financial Services, Human Capital, Marketing and Public Relations, and Social Services.

GSA identified these additions through market research and industry feedback, responding to agency demand for broader service categories under one contract vehicle.

Six Contract Pools and Small Business Opportunities

OASIS+ divides into six distinct pools: one Unrestricted pool and five small business categories covering Total Small Business, 8(a), Women-Owned Small Business (WOSB), HUBZone, and Service-Disabled Veteran-Owned Small Business (SDVOSB).

Eligibility depends on SBA certifications and size standards verified at application. Companies meeting multiple criteria can hold awards across several pools, so an 8(a)-certified firm may compete in both the 8(a) and Total Small Business pools simultaneously.

Each pool operates independently with separate contract awards but shares the same 13 service domains and routes task orders through GSA eBuy. This design helps agencies hit small business targets like HUBZone while retaining access to large contractors when scope demands it. This design helps agencies hit small business targets while retaining access to large contractors when scope demands it.

Continuously Open Solicitation Model

OASIS+ operates through a continuously open solicitation model. On January 12, 2026, GSA's Office of Professional Services and Human Capital released final Phase II amendments on SAM.gov, confirming the rolling approach.

You submit proposals when ready. No fixed deadlines. No periodic recompete windows. GSA evaluates as submissions arrive and awards contracts throughout the vehicle's life, including VOSB-certified contractors in the SDVOSB pool. GSA evaluates as submissions arrive and awards contracts throughout the vehicle's life.

This removes the single-deadline pressure. You have time to gather past performance, refine technical narratives, and wait for new certifications or contract completions before applying. Companies can reapply with updated qualifications.

The open on-ramp eliminates waiting periods for contractors who missed Phase I or need additional pool awards. You set the timeline.

Procurement Consolidation and Executive Order 14240

Executive Order 14240, "Eliminating Waste and Saving Taxpayer Dollars by Consolidating Procurement," directs federal agencies to retire redundant contract vehicles and consolidate purchasing. The order aims to reduce administrative overhead, streamline vendor management, and increase buying power through centralized vehicles.

OASIS+ Phase II directly supports this mandate. By expanding service domains and opening continuous on-ramps, GSA positions OASIS+ as the primary vehicle for non-IT professional services across government. Agencies can now retire agency-specific IDIQs and route orders through one contract suite.

The consolidation shifts billions in fragmented spending onto OASIS+. Contractors gain access to more opportunities through fewer vehicles. Agencies reduce contract administration costs and duplicate evaluation work.

How Task Orders Work Through GSA eBuy

Federal agencies post all OASIS+ task order solicitations through GSA eBuy. Building a compliance matrix for each task order helps you track requirements across the solicitation package. Agencies with Delegation of Procurement Authority can issue task orders directly using the eBuy portal without routing requests through GSA contracting officers.

Contractors holding OASIS+ awards receive automated email notifications when agencies post relevant task orders matching their pool and domain qualifications. You search active opportunities in eBuy, filter by service domain, set-aside type, and agency, then download solicitation packages directly from the system. Proposal submission happens through eBuy as well.

Fair opportunity rules apply to every competed task order. Agencies must provide all qualified contract holders in the relevant pool reasonable notice and a fair chance to compete. Exceptions exist for orders under the simplified acquisition threshold or when only one contractor can meet urgent requirements.

OASIS+ Qualification Requirements and Scoring

OASIS+ uses a self-scoring evaluation methodology. Contractors calculate their own points across five weighted categories, then GSA validates submissions during review.

The primary scoring areas are Qualifying Projects (QPs), Past Performance, Federal Prime Experience, Contractor Business Systems, and Government Facility Clearances and Other Certifications. QPs carry the heaviest weight and require projects demonstrating capability in your chosen service domains.

Unrestricted offerors need QPs with minimum average annual value of $1,000,000. Small business offerors face a $500,000 threshold per QP. Each project must align with at least one of the 13 service domains you select during proposal submission.

Past performance references validate delivery quality. Federal prime experience proves you can manage government contracts directly. Business systems show operational maturity. Facility clearances and certifications add differentiation.

Your domain selections determine which task orders appear in eBuy. Choose domains where you can prove capability through QPs and past performance. A capability matrix helps map your experience to OASIS+ service domains.

Current Award Status and Contractor Base

GSA began issuing OASIS+ awards in 2024 and continues evaluating proposals on a rolling basis through Phase II. As submissions arrive and pass evaluation, GSA adds qualified contractors to the appropriate pools, creating an expanding base.

The rolling approach means the contractor population grows over time. Unlike traditional IDIQ vehicles that award a set number of contracts upfront and close for years, OASIS+ adds new holders continuously as they meet qualification thresholds. This keeps the vendor pool fresh and allows agencies access to emerging capabilities without waiting for recompete cycles.

GSA maintains evaluation standards regardless of submission timing. Each proposal faces the same scoring criteria, minimum thresholds, and validation process.

How GovDash Automates OASIS+ Proposal Development

GovDash's Capability Matrix analyzes OASIS+ domain requirements and maps them against your past performance, showing which of the 13 service domains align with your qualifying projects without manual crosswalking.

When responding to OASIS+ on-ramps or eBuy task orders, GovDash's Compliance Matrix Generation parses requirements across the solicitation package and extracts self-scoring criteria, QP thresholds, past performance documentation rules, and submission instructions into a structured checklist.

AI-Assisted Proposal Drafting accelerates qualifying project descriptions and technical narratives required for OASIS+ self-scoring. The system pulls relevant contract data from your knowledge repository and generates compliant narratives that demonstrate domain capability.

GovDash tracks eBuy notifications, organizes proposal teams, and manages collaborative reviews without version control issues.

Final Thoughts on the OASIS+ On-Ramp

The continuous solicitation model removes the urgency that comes with traditional contract vehicles, giving you space to refine your qualifications and submit when your story is strongest. OASIS+ now covers 13 service domains across six pools, routing task orders through GSA eBuy where agencies post billions in opportunities every year. GovDash tracks those notifications, validates your domain alignment, generates compliance checklists, and writes qualifying project descriptions so you can focus on capture strategy instead of formatting. If you're planning an on-ramp submission or responding to task orders, book a demo to see how we accelerate every phase of the process.
