Acronyms are one of the fastest ways new contractors get lost during the GSA Multiple Award Schedule (MAS) acquisition process, and whether you're new to government contracting or have years of experience, the countless acronyms involved can be difficult to keep up with. From GSA Schedule terms to agency names, government contracting acronyms are often not spelled out and may change over time. As a current or prospective GSA contractor, understanding these acronyms is important as they often appear during proposal preparation, contract maintenance, and conversations with government buyers.
To help you get started, this blog defines the top 25 government contracting acronyms that you’ll see throughout the contracting process so you can navigate the journey confidently.
1. Blanket Purchase Agreement (BPA):
A Blanket Purchase Agreement (BPA) is an agreement established by a government buyer with a contractor to fill repetitive needs for supplies or services (for the set of rules establishing BPAs under the GSA MAS program, you can review FAR 8.405-3). BPAs make it easier for the contractor and buyer to fill recurring needs with the customer’s specific requirements in mind.
2. Commercial and Government Entity (CAGE) Code:
A CAGE Code is a five-character identifier tied to your company's physical address for GSA mailings, payments, and administrative records. You must have a CAGE Code before receiving a GSA Schedule contract. Your CAGE Code is automatically issued through SAM.gov when you register. Note: for international companies, an NCAGE code will be needed.
3. Commercial Sales Practices (CSP):
Commercial Sales Practices (CSP) is a legacy pricing disclosure method for GSA Schedule sales and is now officially replaced by Transactional Data Reporting (TDR) as of April 2026 with MAS Solicitation Refresh #31. Historically, CSP has been the process contractors use to disclose the pricing, terms, and conditions they offer commercial customers. GSA uses such information to identify the customer class receiving the lowest price and negotiate a fair and reasonable discount. CSP was also a form of quarterly sales reporting, but all MAS contractors will be subject to monthly reports under TDR (we’ll cover more on this term below).
4. Contracting Officer (CO):
A Contracting Officer is a federal official authorized to award, administer, renew, or terminate contracts and make related determinations and findings. COs may also be referred to as Procurement Contracting Officers (PCOs). Your appointed CO may change over time, so it is important to stay informed of any potential changes.
5. Contractor Teaming Arrangement (CTA):
A Contractor Teaming Arrangement (CTA) allows Schedule holders to work with other companies to offer a total solution that meets a government customer’s needs. It helps contractors pursue orders they may not be able to win on their own.
6. Cybersecurity Maturity Model Certification (CMMC):
The Cybersecurity Maturity Model Certification (CMMC) is a three-level Department of Defense cybersecurity framework for defense contractors. It helps ensure contractors apply the safeguards needed to protect sensitive information such as Controlled Unclassified Information (CUI) and Federal Contract Information (FCI).
7. Economic Price Adjustment (EPA):
An Economic Price Adjustment (EPA) is a method for updating prices on a GSA Schedule contract. GSA recently consolidated all the EPA clauses into one—552.238-120. Price adjustments can be made based on fixed escalation rates (on 12-month anniversary of the GSA contract), market index, or based on established pricing. The market index adjustments are based on an agreed-upon market indicator when you are preparing your GSA Schedule offer. This acronym should not be mistaken for the Environmental Protection Agency (EPA).
8. Federal Acquisition Regulation (FAR):
The Federal Acquisition Regulation (FAR) is the primary rulebook for federal procurement. Under the current administration, aspects of the FAR, such as FAR Parts 8 and 12, are being reviewed and updated through the Revolutionary FAR Overhaul initiative, or RFO, so it is important to stay up to date on the latest FAR amendments.
9. Federal Acquisition Service (FAS):
The acquisition and procurement arm of the federal government. You may see this term precede other GSA platforms such as the FAS Catalog Platform (FCP), which we’ll discuss below.
10. FAS Catalog Platform (FCP)
The FAS Catalog (FCP) is a web-based application designed for MAS contractors to manage both product and service catalog data. This app replaces the legacy Schedule Input Program (SIP). Its purpose is to provide a more streamlined process for reporting product and service catalog data, such as product descriptions, photos, and pricing information. In return, the information provided within your FCP profile is automatically posted to GSA Advantage! and GSA eLibrary for government buyers to research and purchase.
11. General Services Administration (GSA):
The General Services Administration (GSA) was founded in 1949 and is an independent agency of the United States government that helps manage and support the basic functioning of federal agencies. GSA manages the Multiple Award Schedule (MAS) Program.
12. Government-Wide Acquisition Contract (GWAC):
Government-Wide Acquisition Contracts (GWACS) are multiple-award, Indefinite Delivery, Indefinite Quantity (IDIQ) contracts that government agencies can use to buy IT products and services more efficiently and economically.
13. Indefinite Delivery/Indefinite Quantity (IDIQ):
Indefinite Delivery/Indefinite Quantity (IDIQ) contracts provide an indefinite quantity of services for a fixed time. They are used when a government agency is unable to determine the exact quantities of supplies or services that the government will need during a contract period.
14. Industrial Funding Fee (IFF):
The Industrial Funding Fee (IFF) covers GSA’s cost of operating the Federal Supply Schedules (FSS) program. The IFF is a fixed percentage (usually .75%) of reported quarterly contract sales under the Multiple Award Schedule (MAS) Program that contractors pay. You can also now remit the IFF monthly with your TDR sales reporting.
15. Multiple Award Schedule (MAS):
Multiple Award Schedules (MAS) are long-term governmentwide, Indefinite Delivery, Indefinite Quantity (IDIQ) contracts that provide federal, state, and local government buyers with commercial products and services at pre-negotiated prices and terms such as volume discount pricing.
16. North American Industrial Classification System (NAICS) Codes:
North American Industrial Classification System (NAICS) Codes are a standard used by federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data. NAICS Codes can help determine if you qualify as a small business. You may identify your NAICS Code through https://www.naics.com. You may also notice that your Special Item Numbers (SINs) are cross-walked to NAICS Codes so they are easier to identify within the MAS Program.
17. Office of Management and Budget (OMB):
The Office of Management and Budget (OMB) measures the quality of agency programs, policies, and procedures to see if they comply with the President's policy priorities and coordinate with inter-agency policy initiatives.
18. Request For Information (RFI):
Requests for Information (RFIs) are a market research process agencies use to gauge interest and/or determine if there is a vendor who can provide a desired product and/or service. A procurement officer will issue an RFI prior to releasing a formal RFP/RFQ.
19. Request For Proposal (RFP):
A Request for Proposal (RFP) is a document that solicits a proposal from an agency interested in procurement. RFPs outline the requirements, capabilities, and solutions agencies need a contractor to fill. Once an RFP is released, contractors can bid and submit a response for a chance to win the contract.
20. Request For Quote (RFQ):
A Request for Quote (RFQ) is a document issued by a government agency asking for price estimates from specific contractors and inviting contractors to join the bidding process. RFQs don't often have a whole separate technical component like an RFP and are focused on pricing quotations. You may see these a lot in GSA eBuy.
Below is a graphic describing the differences between RFIs, RFQs and RFPs:
21. System for Award Management (SAM):
The System for Award Management (SAM) is an official website of the U.S. government where contractors can register to do business with the US government, renew their SAM profile, search for contract opportunities, research contract data, and check on wage determinations.
22. Special Item Number (SIN):
A Special Item Number (SIN) categorizes products and services into distinct groupings that contractors offer through their GSA Schedules. The MAS Program has a three-tier hierarchical structure, including Large Categories, Subcategories, and, lastly, SINs. A full list of Large Categories, Subcategories, and SINs can be found on GSA eLibrary.
23. Trade Agreements Act (TAA):
The Trade Agreements Act (TAA) intends to foster fair and open international trade by determining whether foreign products and services can be sold through the federal marketplace. The TAA states that government agencies may only acquire “U.S. -made or designed country end products or services.” Both TAA-compliant and restricted countries may be found on our site.
24. Transactional Data Reporting (TDR):
Transactional Data Reporting (TDR) is now mandatory for all contractors. TDR was created to capture transactional data on procurements across all its Federal Supply Schedules (FSS) contracts, including MAS contracts). TDR removes the requirement for Schedule holders to submit their Commercial Sales Practice (CSP) information and allows GSA to analyze federal spending patterns. MAS contractors have to report their GSA sales monthly under TDR.
25. Unique Entity Identifier (UEI)
An Unique Entity Identifier (UEI) is a 13-character code a business receives when registering in SAM.gov. It is composed of a string of alphanumeric characters used to search, organize, and identify your company instead of searching by your business name. UEIs are required to do business with the government and replaces the former DUNS (Dun and Bradstreet) number.
