What the agency is buying and why it matters

The Federal Acquisition Service (FAS) is seeking proposals from Service-Disabled Veteran-Owned Small Businesses (SDVOSBs) for the One Acquisition Solution for Integrated Services Plus (OASIS+) contract. This is an Indefinite-Delivery, Indefinite-Quantity (IDIQ), Multi-Agency Contract (MAC) for professional services across various domains.

This contract vehicle allows eligible businesses to provide a wide range of professional services to multiple government agencies. Being an awardee on OASIS+ can open doors to numerous task order opportunities, making it a significant contract for growth and stability for SDVOSBs.

Key dates and what happens at the deadline

This solicitation is continuously open, meaning proposals are accepted on an ongoing basis. However, there is a specific deadline for acknowledging Amendment 0009 for offers submitted before its issuance.

If you submitted an offer prior to July 7, 2026, and have not yet received an award or unsuccessful notice, you must acknowledge Amendment 0009 by signing and uploading the SF30 document by July 15, 2026. Failure to meet this deadline may result in your offer being ineligible for further consideration. For new offers submitted after July 7, 2026, you must acknowledge all current amendments within the OASIS+ SubmissionPortal during your offer submission. The OASIS+ SubmissionPortal is open for registration and submissions as of January 12, 2026.

Who this opportunity suits

This opportunity is specifically for Service-Disabled Veteran-Owned Small Businesses (SDVOSBs) that provide professional services. Firms with expertise in various service domains are encouraged to apply, as a single proposal can cover multiple domains.

Businesses must be registered and active in SAM.gov to be eligible. This contract is suitable for established SDVOSBs looking to expand their federal contracting footprint through a major government-wide vehicle.

How to respond

All proposals must be submitted through the OASIS+ SubmissionPortal (OSP). You will need to register on the portal to access and submit your offer. The portal can be accessed by clicking the "View original source" link.

If you submitted an offer before Amendment 0009 (July 7, 2026) and have a pending offer, you must log into Symphony via the portal, navigate to My Company, then Business Factors, and upload the signed SF30 for Amendment 0009 by July 15, 2026. For new offers, you will acknowledge all current amendments directly within the OSP during your submission process.

Practical tips for preparing a competitive response

Carefully review the entire solicitation, including all amendments, before preparing your proposal. Ensure your SAM.gov registration is active, accurate, and complete, as this is a fundamental requirement.

Since you can submit a single proposal for multiple domains, strategically choose the domains where your business has the strongest qualifications and experience. Pay close attention to the OASIS+ Domain Qualifications Matrix and Scorecards (J.P-1) to understand the specific requirements for each domain you target. Organize your proposal clearly and concisely, highlighting your firm's relevant experience and capabilities for each chosen domain.
