Frequently asked questions
What is OASIS+ Phase II?
OASIS+ Phase II is the second solicitation phase of GSA's One Acquisition Solution for Integrated Services Plus contract vehicle, adding 5 new service domains and expanding the small business and socioeconomic set-aside pools established in Phase I.
How do you qualify for OASIS+ Phase II?
To qualify for OASIS+ Phase II, a company must demonstrate relevant past performance through a scored self-scoring document, hold relevant NAICS codes, meet any domain-specific experience requirements, and submit through SAM.gov. Small business pools require active small business status at time of offer.
What is the OASIS+ self-scoring process?
The OASIS+ self-scoring process requires contractors to document and verify past contract experience by domain, project size, and complexity. Points are awarded for relevant experience, past performance ratings (CPARS), relevant degrees and certifications, and small business certifications like 8(a), SDVOSB, or HUBZone.
Can a small business without existing federal contracts compete on OASIS+?
Yes, but it is challenging. OASIS+ rewards proven past performance heavily. Companies with 2-3 relevant prime contracts above the minimum threshold have the highest success rates. Companies with only subcontract experience may qualify but will score lower and face stiff competition from more established firms.
How does OASIS+ compare to GSA Schedule for small businesses?
GSA Schedule is better for commercial services, direct purchasing, and immediate revenue generation. OASIS+ is better for large, complex professional services projects. Most successful small businesses pursue both — the GSA Schedule first for early wins, then OASIS+ once they have 3+ strong past performance citations.
