GovCon has a learning curve—and a lot of the “curve” is acronyms and jargon that show up in every solicitation package.
Below are 25 federal contracting terms you’ll actually see in 2025—written in plain English, with quick context so you know where it appears and why it matters.
How to use this glossary
- If you’re registering: start with SAM.gov, UEI, CAGE.
- If you’re qualifying an opportunity: focus on NAICS, PSC, and set-asides.
- If you’re bidding: pay attention to RFI / Sources Sought / RFP / RFQ / IFB, plus SOW/PWS, QASP, and CLIN.
Core platforms and identifiers (vendor onboarding)
SAM.gov
The main federal site where many opportunities are posted and where vendors register to do business with the government. If your SAM registration isn’t active, you usually can’t receive award.
UEI
The Unique Entity Identifier used to identify your business across federal systems (it replaced DUNS). You’ll see it in SAM.gov and on many award/contract documents.
CAGE
The Commercial and Government Entity code used to identify vendors—common in DoD and many subcontracting flows. You’ll often see it alongside UEI.
PSC (Product Service Code)
A code that classifies what the government is buying (product or service). It’s frequently used to filter opportunities and quickly understand the type of work.
Classification and eligibility (does this fit you?)
NAICS
North American Industry Classification System: the industry classification code tied to the solicitation and used for size standards. It affects whether you qualify for small business status on that opportunity.
Set-aside
An opportunity restricted to certain categories (e.g., small business). If you don’t meet the set-aside requirement, you’re typically ineligible to bid as prime.
8(a)
A Small Business Administration (SBA) program for eligible socially and economically disadvantaged businesses. You’ll see it as a set-aside or evaluation preference on some solicitations.
HUBZone
Historically Underutilized Business Zone program. Some opportunities are set aside for HUBZone-certified firms, or give HUBZone evaluation preference.
WOSB / EDWOSB
Women-Owned Small Business / Economically Disadvantaged WOSB programs. Common as set-asides in specific NAICS codes and industries.
SDVOSB
Service-Disabled Veteran-Owned Small Business. Often appears as a set-aside category (especially in VA and defense-adjacent work).
Market research and solicitation types (what stage is this?)
RFI
Request for Information. Not a solicitation for award—more like a structured way for the agency to learn what the market can do.
Sources Sought
An early market research notice used to gauge interest and capability. It often signals an upcoming procurement (and is a chance to influence requirements).
RFP
Request for Proposal: a solicitation asking vendors to propose a solution and price.
RFQ
Request for Quote: often more structured and pricing-focused (common under simplified acquisition or established schedules/vehicles).
IFB
Invitation for Bids: typically award is based largely on price with a clear, well-defined requirement (more “bid the spec” than “propose a solution”).
Contracting documents and scope (what exactly are they asking for?)
SOW / PWS
Statement of Work / Performance Work Statement: the document that describes the work, deliverables, constraints, and acceptance criteria. This is usually the “source of truth” for scope.
QASP
Quality Assurance Surveillance Plan: explains how the government will inspect/monitor performance. It affects how you plan staffing, reporting, and quality control.
Tip: always open the solicitation “attachments.” That’s often where the real requirements live (templates, pricing sheets, compliance matrices, past performance instructions, etc.).
Contract structure and ordering (how will work get issued?)
CLIN / SLIN
Contract Line Item Number / Sub-Line Item Number: how the government structures deliverables and pricing on the contract. CLINs drive invoicing, payment, and what’s considered “done.”
IDIQ
Indefinite Delivery / Indefinite Quantity: a contract framework for future task orders.
BPA
Blanket Purchase Agreement: an agreement for recurring purchases under set terms.
Task Order / Delivery Order
An order issued under an existing vehicle (often an IDIQ). The order—not the base vehicle—usually contains the specific scope, period of performance, and funding.
Rules, roles, and evaluation (how decisions get made)
FAR
Federal Acquisition Regulation: the primary rulebook for federal buying. Solicitations and contracts reference FAR clauses that create obligations (reporting, invoicing, security, etc.).
CO / COR
Contracting Officer (CO) has the legal authority to bind the government (award, modify, terminate). Contracting Officer’s Representative (COR) manages day-to-day performance. If it’s not from the CO, assume it’s not a contract change.
Best Value
An evaluation approach where the lowest price isn’t automatically the winner.
CPARS
Contractor Performance Assessment Reporting System: the government’s past performance record for contracts. Strong CPARS can directly improve win probability; weak CPARS can hurt future awards.
