OASIS+ (formerly OASIS SB)

Now Open: Continuous On-Ramp

OASIS+ is the successor to OASIS and OASIS Small Business, and it is open for proposals. GSA has kept all six OASIS+ solicitations continuously open since January 12, 2026, with no closing date, so your firm can submit as soon as its score and past performance are ready.

IMPORTANT: OASIS+ is open now. GSA is accepting proposals continuously under all 13 domains.

Introduction to OASIS+

OASIS+ (One Acquisition Solution for Integrated Services Plus) is a GSA multiple-award, Best-in-Class IDIQ contract that helps federal agencies buy integrated services. It combines the scope of the original OASIS with Building Maintenance and Operations (BMO) and Human Capital and Training Solutions (HCaTS), and adds new service areas.

There are six solicitations: Total Small Business, SBA-certified 8(a), HUBZone, Service-Disabled Veteran-Owned (SDVOSB), Women-Owned (WOSB), and Unrestricted. Contracts run for a five-year base period plus one five-year option, up to ten years. Proposals are submitted through GSA’s OASIS+ Submission Portal, and each one is scored on points: 36 for small businesses and 42 for unrestricted firms.

Our Costs
ServiceFeeDetails
OASIS+$6,000.00$6,000 base fee includes 1 set-aside with up to 3 domains.
Additional Set-Aside$1,000.00Includes up to 3 domains.
Additional Domains$500.00Each.
OASIS+ Mods to Add Domains$2,500.00Includes up to 3 domains; $500 per each additional domain.
OASIS+ Highlights
  • Best-in-Class (BIC): a GSA governmentwide designation, so agencies are strongly encouraged to use OASIS+ for integrated services.
  • 13 domains: Technical and Engineering, Research and Development, Management and Advisory, Environmental, Intelligence Services, Enterprise Solutions, Facilities Services, Logistics, Business Administration, Financial Services, Human Capital, Marketing and Public Relations, and Social Services.
  • Six tracks, each with its own contract: Total Small Business, 8(a), HUBZone, SDVOSB, WOSB, and Unrestricted.
  • Up to ten years: a five-year base period plus one five-year option.
  • Task orders are competed only among OASIS+ contract holders in the matching domain, so they are not visible to the general public.
  • The original OASIS was heavily used by DoD, DHS, VA and NASA, and OASIS+ is expected to exceed those sales levels.
OASIS+ Key Information
  • Continuous on-ramp: GSA accepts proposals until further notice, with no closing date.
  • Scoring: 36 points for small businesses and 42 points for unrestricted businesses. Most preparation experts recommend a cushion of 3 to 5 points above the minimum.
  • Non-mandatory elements such as business systems, certifications, and clearances can add substantial points to a proposal’s score.
  • GSA checks for AI being used in the proposal process and this can cause a rejection of a proposal.

Benefits of OASIS+
  • OASIS+ has a Best-in-Class designation, meaning it is a preferred place for contracting officers to procure integrated services.
  • It is a closed competition: only firms holding an OASIS+ contract in a domain can see and bid on task orders in that domain.
  • The contract can last up to ten years (a five-year base period plus one five-year option).
  • Thirteen domains and six tracks, so a diverse group of firms can benefit, including 8(a), HUBZone, SDVOSB and women-owned small businesses.
  • Because proposals are accepted continuously, your firm can apply when it is ready instead of waiting for a solicitation window.

How OASIS+ Scoring Actually Works

GSA doesn’t read a narrative and decide if it likes your firm — every OASIS+ offer is graded against a fixed point scale called the Qualification Matrix. You claim credits for your best past projects plus a handful of corporate-level items (business systems, clearances, certifications), add them up, and your total has to clear the bar for your track: 36 points if you’re bidding small business, 42 if you’re bidding unrestricted. Below is the credit structure for both, including a few rules that are easy to misapply if you’re scoring your own firm for the first time.

Run your numbers in our OASIS+ points calculator

Small Business Track — 36-Point Threshold

Credit AreaPer ProjectCeilingNotes
Domain match420Awarded when the project's work falls inside the Domain you're bidding.
Contract size / staffing1–26+1 if the project averaged $1M+ per year or ran 5+ FTEs; +2 at $4M+ per year or 20+ FTEs. This has to be the average annual value — total contract value divided by its years of performance — not the full lifetime award amount.
Past performance—3Not a per-project score. It's based on how many of your submitted projects carry a positive CPARS or J.P.-6 rating: 3 rated projects earns 1 point, 4 earns 2, and all 5 earns the full 3.
Integrating experience15Credit for showing either 5+ labor categories or 3+ functional areas on a project — pick whichever applies, since the two don't stack. Max 1 point per project.
Management & staffing1–35Credit for managing 3+ first-tier subcontractors, absorbing a staffing surge, or fielding 5+ cleared personnel on the project.

Small Business Track — Corporate-Level Credits

ItemPoints
An adequate-system letter from DCAA, DCMA, or a cognizant CFA covering your accounting system2
Facility clearance: SECRET is worth 1 point everywhere. A 2nd point for TOP SECRET only applies if you're bidding the Enterprise Solutions or Intelligence Services Domain — every other Domain caps this credit at 1 point regardless of clearance level.1–2
Any current certification — CMMI Level 2+, ISO 9001:2015, ISO 27001:2022, ISO 22301, or CMMC Level 2+. Having more than one on file doesn't add extra points.1
Federal prime experience on multiple-award contracts, 1 point per contractup to 4
Delivered work for 3 or more different federal agencies1
Task orders won competitively under another multiple-award vehicle (SEWP, GSA Schedule, etc.), 1 point eachup to 4

Sample build: getting to 36

  • 5 Domain-matched projects: 5 × 4 = 20
  • Contract size: two projects at $4M+/yr (+2 each), one at $1M+/yr (+1) = 5
  • Past performance: 3 of the 5 projects positively rated = 1
  • Integrating experience: 3 projects qualify, 1 point each = 3
  • Management & staffing: spread across projects = 3
  • Accounting system letter = 2
  • Agency diversity = 1
  • One certification on file = 1
  • Running total: 36 — right at the line, with no room to spare

Unrestricted Track — 42-Point Threshold

Credit AreaPer ProjectCeilingNotes
Domain match420Same as the small-business track: the project's work has to sit inside your target Domain.
Contract size / staffing1–26+1 at $2.5M+ average annual value or 12+ FTEs; +2 at $10M+ average annual value or 50+ FTEs. Same annual-value rule as above — divide by years of performance, don't use the total award.
Past performance—3Identical mechanic to the small-business track: 3 positively-rated projects = 1 point, 4 = 2, 5 = 3. It is not scored project by project.
Integrating experience145+ labor categories or 3+ functional areas, one or the other, capped at 1 point per project.
Management & staffing1–36Subcontractor management, staffing surges, or cleared personnel on the project.

Unrestricted Track — Corporate-Level Credits

ItemPoints
An adequate-system letter from DCAA or DCMA covering your accounting system2
Facility clearance: SECRET is worth 1 point everywhere; the 2nd TOP SECRET point is exclusive to the Enterprise Solutions and Intelligence Services Domains, capped at 1 point in every other Domain1–2
Any current certification — CMMI Level 2+, ISO 9001:2015, ISO 27001:2022, ISO 22301, or CMMC Level 2+ (one point regardless of how many you hold)1
At least one federal multiple-award prime contract1
Delivered work for 3 or more different federal agencies1
Approved purchasing and/or estimating business systemsup to 2

Sample build: getting to 42

  • 5 Domain-matched projects: 5 × 4 = 20
  • Contract size: mix of $2.5M+ and $10M+ projects = 5
  • Past performance: 4 of the 5 projects positively rated = 2
  • Integrating experience: 3 projects qualify, 1 point each = 3
  • Management & staffing: spread across projects = 5
  • Accounting system letter = 2
  • TOP SECRET clearance, bidding in the Intelligence Services Domain = 2
  • One federal multiple-award prime contract = 1
  • Agency diversity = 1
  • One certification on file = 1
  • Running total: 42 — exactly at the line

These are planning examples, not guarantees — GSA's reviewers make the final call on every project you submit, which is why most consultants recommend banking 3 to 5 points above the minimum rather than filing right at the threshold.
