What the agency is buying and why it matters
The General Services Administration (GSA), Federal Acquisition Service (FAS), is seeking proposals from women-owned small businesses for the One Acquisition Solution for Integrated Services Plus (OASIS+) contract. This is a multi-agency contract (MAC) for integrated professional, scientific, and technical services across various domains. This opportunity allows vendors to provide a wide range of services to multiple government agencies through a single contract vehicle, which can be a significant advantage for business growth.
The solicitation is continuously open, meaning there are ongoing opportunities for new businesses to join or for existing awardees to compete for additional domains as government needs change. There is no fixed timeline for awards; timelines will vary based on proposal volume and resource availability.
Key dates and what happens at the deadline
This solicitation was published on July 17, 2026, as Amendment 0009 to solicitation 47QRCA23R0005. The deadline for submitting new proposals is January 11, 2027, at 4:00 PM ET. All proposals must be submitted through the OASIS+ SubmissionPortal (OSP).
For offerors who submitted a proposal prior to Amendment 0009 and have not yet received an award or unsuccessful notice, a signed SF30 must be uploaded to the Business Factors section in Symphony by July 15, 2026. Failure to submit this signed SF30 by the deadline may result in the offer being ineligible for further consideration. This SF30 is for amendment acknowledgment only; no revised proposal documents or additional supporting materials should be submitted at this time.

This opportunity is specifically for Women-Owned Small Businesses (WOSB) that provide professional, scientific, and technical services. Firms should be active and registered in SAM.gov. Businesses with expertise across multiple domains are encouraged to propose for multiple domains under a single solicitation.
This contract is suitable for businesses looking to expand their reach across various federal agencies and secure long-term government contracts through an Indefinite-Delivery, Indefinite-Quantity (IDIQ) vehicle.
How to respond
To respond to this solicitation, you must first be registered and active in SAM.gov. All proposals must be submitted through the OASIS+ SubmissionPortal (OSP). The OSP has been open for registration and submission of offers since January 12, 2026.
New offerors submitting after Amendment 0009 must acknowledge all current amendments in the OSP during offer submission. A signed SF 33 is required as part of all offer submissions. Offerors with pending offers from before Amendment 0009 must upload a signed SF30 to the Business Factors section in Symphony by July 15, 2026, for each applicable RFP.
Practical tips for preparing a competitive response
Carefully review the entire solicitation and all amendments. Ensure your business is fully compliant with all requirements, especially those related to Women-Owned Small Business status and SAM.gov registration. Pay close attention to the OASIS+ Domain Qualifications Matrix and Scorecards (J.P-1) to understand the specific criteria for each domain you wish to pursue.
Since this is a continuously open solicitation, it is important to submit a well-prepared proposal promptly. While there is no fixed award timeline, a complete and compliant submission will position your firm for consideration. Double-check all required attachments, such as the Project Verification Form (J.P-3) and the Cost/Price Template (J.P-9), to ensure accuracy and completeness before submission.
