Buyers Guidance and Resources
How to Use OASIS
The GSA OASIS Tier 3, Best-in-Class (BIC) solutions make procuring complex professional services expedient by maximizing streamlined acquisition processes. The following resources are designed to help buyers use the OASIS suite of contracts.
Two ways to access OASIS:
- Direct Acquisition - GSA issues a Delegation of Procurement Authority to the customer agency Ordering Contracting Officer (OCO) who performs the acquisition; or
- Assisted Acquisition - GSA performs the acquisition on behalf of the customer agency and provides post-award support, as negotiated with the customer. An Inter-Agency Agreement is required.
The OASIS Master Contract and OASIS SB Master Contract will help your agency acquire professional services for integrated solutions more efficiently and economically.

GSA offers an optional OASIS scope review that analyzes the scope and Pool assignment of your proposed requirement.
To request a scope review you must:
- Complete the OASIS Scope Review Online form.
- Use the OASIS NAICS Code definitions document [PDF - 177 KB] to choose the code representing the principle purpose of your requirement
- Input that NAICS code and corresponding pool in the Primary NAICS field of the form. Example for military engineering: “NAICS 541330 Exception A (Pool 3)”
- Complete your Statement of Work (SOW)
- Complete your Independent Government Cost Estimate (IGCE) using your Agency’s government estimate with labor categories and hours template or generated using the OASIS Price Estimating Tool
We cannot complete the scope review until the completed scope review form, SOW and IGCE have been received. Note: If you do not hear back within five business days of submitting all documents, email OasisScopeReviews@gsa.gov for update.

Email links to Contractor pools are in the table below.
Warning: It is strictly prohibited to send emails by way of the following Pool Links if you are not an authorized government official. Non-authorized personnel may contact the Prime Contract holders individually but not through the use of the following Pool Links.
- The following OASIS Unrestricted (U), OASIS Small Business (SB), and OASIS 8(a) Pool Links generate a group email to the official Points of Contact for all the Prime Contract holders in the respective Pools
- The primary purpose of the Pool links are for authorized government officials issuing Requests for Proposals (RFP), Requests for Information (RFIs), or other Market Research requests to the OASIS U, OASIS SB, or OASIS 8(a) Prime Contract holders by Pool.
Important: Each Pool is a separate Multiple Award Task Order Contract (MATOC). When issuing an RFP, only one Contract Vehicle (OASIS U, OASIS SB, or 8(a) pools) and one Pool can be solicited. Pool selection is based on the predominate NAICS Code (definitions by OASIS Pool Numbers) [PDF - 177 KB] assigned to the solicitation (see Ordering Guide Appendix A [DOCX - 384 KB])
Select the OASIS Unrestricted pool link that corresponds to the predominate North American Industry Classification System (NAICS) code when issuing a RFP that is not a Total Small Business Set- Aside. Select the OASIS SB pool link that corresponds to the predominate NAICS code when issuing a RFP that is a Total Small Business Set-Aside (FAR 19.502-2).
Note: If clicking on the email link does not automatically pull up your email drafts, copy and paste the link into your email. Please do NOT carbon copy (cc) the OASIS@gsa.gov or OASISSB@gsa.gov in your email to OASIS contractors
In March 2022, OASIS adopted Symphony Procurement Suite (the commercial-off-the-shelf software), to issue, manage and award task orders.
Symphony is a full lifecycle procurement Software as a Service (SaaS) allowing government organizations to manage complex contracts. Symphony ensures organizations are purchasing according to fair opportunity laws and rules. Symphony provides users increased transparency and integrity at both the master contract level and task order level.

The OASIS program has created a variety of crosswalks to guide buyers through the acquisition process.
The standard federal agencies use to classify business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy.
- All codes/exceptions in a pool share a common small business (SB) size standard.
- Agencies can solicit task order proposals from contractors holding awards in the pool with the NAICS code that matches the agency's requirement.
The core disciplines/scopes of the contracts include:
The labor categories are aligned with occupations, as outlined in the SOC) system.Standard Occupational Classification (
- OASIS offers more meaningful proposed rate comparisons at the Task Order level (apples to apples)
- 104 OASIS LCATs (individual and groups priced at the master contract level)
- 127 OMB SOC occupations, and
- 1,000 typical industry job titles
- The remaining 840 SOC occupations can be added and priced at the task order level as ‘ancillary labor'
A federal agency responsible for assisting the president in meeting policy, budget, management and regulatory objectives and to fulfill the agency’s statutory responsibilities.
The OASIS Labor Category Crosswalk Table [XLSX - 81 KB] compares Industry's functional job descriptions and specific the Office of Management and Budget (OMB) Standard Occupational Classification (SOC) system occupational descriptions. In this table, you will find more than a thousand industry job titles with suggested SOC occupation and OASIS LCAT matches.
The OASIS Table of PSC codes by OASIS pool number [XLSX - 67 KB] is excerpted from Federal Procurement Data System-Next Generation (FPDS-NG) and only includes those in scope. Select the link to search for your Pool number and the various possible PSC Codes that may apply. (Note: The white drop down arrows on the table will streamline the process.)
Note: Ordering Contracting Officers (OCOs) are required to identify, in each task order solicitation, the PSC that represents the principal nature of the work, and report these PSCs in FPDS-NG.
The core disciplines/scopes of the contracts include:
OASIS Unrestricted is a Full and Open contract whereas OASIS Small Business is a 100 percent Small Business Set-Aside contract (FAR 19.502) with the ability to do Socio-Economic Set-Asides (FAR 19.8 thru FAR 19.15) at the task order level. The OASISSubPools were developed to provide the 8(a) community expanded access to the OASIS Best-in-Class contract program while creating more options for federal agencies to meet their 8(a) business development program goals through both competitive 8(a) set-asides and 8(a) directed task order awards.
OASIS Unrestricted and OASIS Small Business are a family of 7 separate Governmentwide Multiple Award, Indefinite Delivery, Indefinite Quantity (MA-IDIQ) task order contracts that span 28Codes and 6 NAICS Code Exceptions under the economic subsector 541 - Professional, Scientific, and Technical Services.
OASIS contract end dates:
- Unrestricted: September 2, 2024
- Small Business: December 19, 2024
- 8(a): December 19, 2024
In accordance with FAR 52.216-22, Indefinite Quantity, paragraph (d), any task order issued during the active period of performance of the master contracts may proceed up to five years following the expiration of the contract ordering period. (Eg., a task order issued on the last day of the IDIQ's active period of performance may be issued for a base and four option periods, and all option periods can be exercised per the Ordering Contracting Officer's (OCO) determination).
The OASIS contracts have different start dates, due to onramps that followed the initial awards; therefore, we aren't publishing the start date of the contracts. If you need to know a specific contract's start date, please contact the OASIS Program Office at email@example.com.
Below are copies of the OASIS Unrestricted, OASIS Small Business Contracts, and OASIS Small Business 8(a) Subpool Contracts:
