OASIS+ is GSA's premier professional services contract vehicle, replacing the original OASIS contracts. GovCert automates domain selection, contract history mapping, qualifying project narratives, and Symphony portal submission for $1,000 — a fraction of the $5,000-$20,000 consultants charge.

What Is OASIS+?
OASIS+ (One Acquisition Solution for Integrated Services Plus) is GSA's next-generation professional services Government-Wide Acquisition Contract (GWAC). It replaces the original OASIS contracts and serves as the federal government's primary vehicle for acquiring complex, integrated professional services across multiple disciplines.
OASIS+ is organized into domain-based contract families — including Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental, and Enterprise Solutions — with both unrestricted and set-aside tracks for small business, 8(a), HUBZone, SDVOSB, and WOSB. Task orders under OASIS+ can be worth hundreds of millions of dollars, making it one of the highest-value contract vehicles in the federal marketplace.
The challenge is the application itself. OASIS+ uses a scored evaluation system where applicants must demonstrate specific contract experience thresholds — minimum dollar values, project complexity, and relevance to the selected domains. Most businesses struggle with domain selection, project mapping, and the narrative format required by GSA's Symphony evaluation portal.
How GovCert Helps
GovCert automates the strategic and documentation-heavy parts of the OASIS+ application:
- Domain Selection Analysis: Upload your contracts, task orders, and capability statements. GovCert analyzes your actual work history and scores your eligibility across all OASIS+ domains. It identifies which domains you can win and which ones lack sufficient qualifying experience — so you focus your application where it counts.
- Contract History Mapping: OASIS+ requires demonstrating contract experience at specific dollar thresholds per domain. GovCert maps each of your past contracts to the applicable NAICS codes, service categories, and domain criteria. It flags gaps in dollar value, period of performance, or scope alignment before you submit.
- Qualifying Project Narratives: Each domain requires detailed project narratives describing the scope, complexity, relevance, and outcomes of qualifying contracts. GovCert generates narratives from your uploaded documentation — structured to match GSA's evaluation criteria with emphasis on the scoring factors that matter most: contract value, multi-disciplinary scope, and performance outcomes.
- Relevant Experience Matrix: GovCert builds a comprehensive matrix linking your contracts to OASIS+ evaluation criteria, making it easy to see at a glance which projects support which domains and where additional documentation may strengthen your proposal.
- Set-Aside Track Guidance: If your firm holds socioeconomic certifications (8(a), HUBZone, SDVOSB, WOSB), GovCert identifies which set-aside pools offer the strongest competitive advantage based on your experience profile and recommends the optimal application strategy.
- Symphony Portal Guide: Step-by-step walkthrough of GSA's Symphony submission portal with copy-to-clipboard buttons, field-by-field instructions, attachment formatting requirements, and character limits matching the actual system. Know exactly what goes where before you start entering data.
What Does It Cost?
GovCert costs $1,000 for complete OASIS+ application preparation. Traditional OASIS consultants charge between $5,000 and $20,000 per domain — and many firms apply for multiple domains, driving costs even higher. With GovCert, the flat price covers all domains you apply for, unlimited narrative revisions, and human support at no additional cost.
Who Qualifies for OASIS+?
OASIS+ eligibility depends on the specific domain and track you are applying for. General requirements include:
- Demonstrated contract experience in the domain's service categories at required dollar thresholds
- Active SAM.gov registration with a valid Unique Entity Identifier (UEI)
- Qualifying NAICS codes that align with the domains you are applying for
- Past performance references from government or commercial customers
- For set-aside tracks: current SBA certification (8(a), HUBZone, SDVOSB, or WOSB as applicable)
- Adequate financial capacity and organizational resources for large-scale professional services delivery

Frequently Asked Questions
What is OASIS+ and how is it different from OASIS?
OASIS+ is the successor to GSA's original OASIS contracts, consolidating multiple professional services vehicles into a single, domain-based framework. Unlike the original OASIS, which used pool-based structures, OASIS+ organizes offerings into domains such as Management and Advisory, Technical and Engineering, and Research and Development. It also introduces continuous on-ramping, allowing new contractors to apply during open enrollment periods rather than waiting for a single solicitation window.
How many domains should I apply for?
Apply for every domain where you have strong qualifying contract experience that meets the dollar value and complexity thresholds. There is no penalty for applying to multiple domains, and each domain you hold opens access to different task order competitions. GovCert scores your contract history against all domains and recommends where your experience is strongest, so you can prioritize your effort.
What are qualifying projects?
Qualifying projects are past contracts or task orders that demonstrate your firm's experience in a specific OASIS+ domain. Each domain has minimum dollar value thresholds and scope requirements. Projects must show relevant professional services work, measurable outcomes, and alignment with the domain's service categories. GovCert extracts qualifying project details from your uploaded contracts and generates compliant narratives formatted for the Symphony evaluation portal.
When is the next OASIS+ on-ramp?
OASIS+ uses a continuous on-ramping model, meaning GSA opens application windows periodically rather than holding a single competition. Check sam.gov and the GSA OASIS+ website for current on-ramp announcements and deadlines. GovCert keeps your application materials ready so you can submit quickly when an on-ramp opens for your target domains.
How much does OASIS+ application help cost?
Traditional OASIS consultants charge $5,000 to $20,000 per domain, with costs increasing for multi-domain applications. GovCert provides complete OASIS+ application preparation — domain analysis, contract mapping, qualifying project narratives, and Symphony portal guidance — for a flat $1,000 covering all domains. Unlimited revisions and human support are included.
