CIO-SP4
Contracts

The planned $50 billion successor to NIH's CIO-SP3 IT services GWAC. CIO-SP4 spent years tied up in bid protests and was never awarded. In early 2026 NITAAC cancelled the solicitation, citing the governmentwide push to consolidate IT contracts under GSA. Companies that had been positioning for CIO-SP4 have largely turned to GSA vehicles such as Alliant, Polaris, OASIS+, and the Multiple Award Schedule instead.

Commercial Off-The-Shelf

COTS
Contracts

Commercial Off-The-Shelf describes a commercial product sold in substantial quantities in the open market and offered to the government in the same unmodified form ordinary buyers get. COTS items receive lighter-touch treatment under the FAR's commercial item rules, since the government is buying something already proven and priced by the marketplace rather than a custom build.

Contract Data Requirements List

CDRL
Contracts

A Contract Data Requirements List is the contract exhibit, built on DD Form 1423, that spells out every data deliverable a contractor owes the government under a defense contract (reports, drawings, manuals, and the like), along with format, frequency, and distribution instructions. Each CDRL line item points to a Data Item Description defining exactly what that deliverable must contain.

Contract Line Item Number

CLIN
Contracts

A Contract Line Item Number is the unique numeric identifier assigned to each distinct item, service, or effort priced and tracked separately within a contract. CLINs let contracting officers and contractors break a single award into billable, fundable, reportable pieces, separating base work from options, labor from travel, or one deliverable from another.

Cost Accounting Standards

CAS
Contracts

Cost Accounting Standards are the 19 federal rules governing how contractors measure, assign, and allocate costs to government contracts, meant to keep cost accounting consistent across the industry. Contractors that cross certain contract-value thresholds must formally disclose their cost accounting practices and apply them consistently, and CAS noncompliance can trigger price adjustments or penalties.

Cost-Plus-Fixed-Fee

CPFF
Contracts

A Cost-Plus-Fixed-Fee contract reimburses the contractor for all allowable incurred costs and pays a fee that's fixed at award and doesn't change with actual cost performance, except for scope changes. It suits research, development, or services where requirements are too uncertain to price on a fixed basis, but gives the contractor little built-in incentive to control costs.

Cost-Plus-Incentive-Fee

CPIF
Contracts

A Cost-Plus-Incentive-Fee contract reimburses allowable costs and pays a fee that moves up or down from a negotiated target based on how actual costs compare to that target, within a set minimum and maximum. The sliding fee formula is meant to motivate the contractor to manage costs efficiently on cost-reimbursement work where a firm price isn't feasible.

Cost-Plus-Percentage-of-Cost

CPPC
Contracts

A pricing arrangement where the contractor's fee is calculated as a percentage of its costs, so the more it spends, the more it earns. Federal law prohibits this system for government prime contracts and subcontracts because it rewards overspending. It rarely shows up by name. Instead it hides in terms like a subcontract markup applied to actual costs with no ceiling, which is why contracts and pricing teams check subcontract terms for it.

F

Final Proposal Revision

FPR
Contracts

A Final Proposal Revision is an offeror's last, formal chance to amend its proposal in a negotiated procurement, submitted after discussions close and by a common cutoff date the contracting officer sets. The government evaluates FPRs as submitted and generally makes award without requesting further changes, making it the last word before source selection.

Firm-Fixed-Price

FFP
Contracts

A Firm-Fixed-Price contract sets a single price for specified supplies or services that doesn't change regardless of the contractor's actual cost experience, putting full cost risk on the contractor. It's the government's preferred contract type whenever requirements are well-defined and cost risk can reasonably be estimated in advance.

Fixed-Price Incentive

FPI
Contracts

A Fixed-Price Incentive contract sets a target cost, target profit, and price ceiling, then adjusts the contractor's final profit up or down from the target using a pre-agreed share ratio based on whether actual costs land above or below that target. It rewards cost control while still capping the government's price exposure at the ceiling.

Fixed-Price with Economic Price Adjustment

FP-EPA
Contracts

A fixed-price contract that allows the price to be revised up or down if specific conditions change, such as published labor or material indexes, established catalog prices, or actual costs of certain inputs. It's used on longer contracts where market prices are likely to move in ways neither side can predict. The adjustment clause defines exactly what triggers a change and how it's calculated, so the contractor isn't stuck absorbing inflation and the government isn't paying a large contingency up front.

G

Government Furnished Equipment

GFE
Contracts

Government Furnished Equipment is durable, nonexpendable equipment the government owns and provides to a contractor for use in performing a contract, rather than having the contractor buy or lease it. The government retains title throughout, and the contractor is accountable for tracking, maintaining, and returning it; this is distinct from Government Furnished Material, which the contractor consumes or builds into deliverables.

Government-Furnished Property

GFP
Contracts

Any property the government owns or acquires and provides to a contractor to perform a contract. That includes equipment, materials, special tooling, and test equipment. Government-furnished equipment (GFE) is one type of GFP. Contractors that receive GFP must track, maintain, and report on it under FAR Part 45 and the contract's property clauses, so proposals that rely on it should say exactly what they expect the government to provide and when.

Government-Wide Acquisition Contract

GWAC
Contracts

A Government-Wide Acquisition Contract is a multiple-award, indefinite-delivery vehicle that one executive agent (typically GSA, NIH, or NASA) runs so any federal agency can order information technology products, services, or solutions off it without running its own competition. GWACs give agencies fast, pre-competed access to vetted IT contractors for task orders of virtually any size and scope.

GSA Schedule

Contracts

A GSA Schedule is a pre-negotiated, indefinite-delivery contract that GSA awards to commercial vendors, letting any federal, state, or local agency buy their products or services at pre-vetted prices and terms without running a full competition. Holding a Schedule contract (also called the Multiple Award Schedule, or MAS) is one of the most common ways contractors reach a broad swath of government buyers.

I

Indefinite Delivery Indefinite Quantity

IDIQ
Contracts

Contract type (FAR 16.504) that establishes terms, a ceiling price, and an umbrella scope for future orders without committing the government to a specific quantity upfront. Agencies issue task or delivery orders against the IDIQ as needs arise, locking in pricing and pre-vetted vendors while keeping ordering flexible.

Independent Research and Development

IR&D
Contracts

Contractor-funded research and development (covering basic research, applied research, development, or systems/concept studies) undertaken without a specific government contract requiring it. Costs are tracked separately from contract performance and, under DFARS 231.205-18, may be recovered as an allowable indirect cost, with added reporting once spending crosses defined thresholds.

Information Technology Enterprise Solutions-3 Services

ITES-3S
Contracts

The Army's multiple-award IDIQ for IT services worldwide, managed by the Computer Hardware, Enterprise Software and Solutions (CHESS) office. It covers work like cybersecurity, IT operations, systems engineering, and enterprise IT support. It has a ceiling of about $12.1 billion, is held by a mix of large and small businesses, and can be used by other federal agencies, although the Army is its main customer. The Army is planning a successor, ITES-4S, so capture teams tracking Army IT work watch that recompete closely.

Invitation for Bid

IFB
Contracts

Formal solicitation method under FAR Part 14 used for sealed bidding when requirements are clearly defined and price alone decides the winner. Bidders submit sealed, unnegotiated bids, and award goes to the lowest responsive, responsible bidder. This differs from an RFP, which allows negotiation and tradeoffs among price and non-price factors.

N

NASA Solutions for Enterprise-Wide Procurement

NASA SEWP
Contracts

NASA-managed Government-Wide Acquisition Contract (GWAC) that any federal agency can use to buy IT hardware, software, and related services from pre-competed, pre-vetted contract holders. It's popular because orders can be placed and awarded in weeks rather than months, without agencies running their own full competition.

Network-Centric Solutions-2

NETCENTS-2
Contracts

A family of Air Force multiple-award IDIQ contracts for IT products, network operations and infrastructure, application services, enterprise integration, and IT professional services, with both full-and-open and small business pools. NETCENTS-2 was the Air Force's primary IT vehicle for about a decade but no longer accepts new orders. Its products work moved to 2GIT, a set of GSA-run blanket purchase agreements, and its services work now goes out through other Air Force and governmentwide vehicles. You'll still see it cited often in past performance.

NIH Information Technology Acquisition and Assessment Center

NITAAC
Contracts

The National Institutes of Health office that ran three governmentwide IT contracts, CIO-SP3, CIO-SP3 Small Business, and CIO-CS. These were among the most widely used GWACs in government. Following the 2025 executive order that consolidated governmentwide IT contracts under GSA, NITAAC announced it was sunsetting. The last day to award new orders is October 29, 2026, and program functions end December 31, 2028. Agencies are moving new requirements to GSA vehicles, so contractors that depended on CIO-SP3 are shifting their pipelines accordingly.

Non-Disclosure Agreement

NDA
Contracts

Agreement in which parties commit not to disclose confidential information exchanged during teaming discussions, proposal development, or contract performance. In GovCon, an NDA is typically signed before a prime and sub exchange proprietary technical approaches, pricing strategy, or past performance data while pursuing an opportunity together.

Nontraditional Defense Contractor

Contracts

A company that hasn't held a DoD contract or subcontract subject to full Cost Accounting Standards coverage in the year before a solicitation, as defined under 10 U.S.C. 3014. The designation exempts qualifying firms from certain regulatory requirements like CAS, and factors into eligibility and cost-share rules for prototype Other Transaction Agreements.

Not-to-Exceed

NTE
Contracts

A ceiling amount that a contract, order, or line item can't go over without a formal modification. NTE amounts show up most often in undefinitized contract actions, where work starts before final pricing is negotiated, and on time-and-materials or labor-hour work, where the contractor bills actual hours but total cost stays capped. Contractors need to track spend against the NTE closely, since costs incurred above it may not be reimbursed.

S

SeaPort Next Generation

SeaPort-NxG
Contracts

The Navy's multiple-award IDIQ vehicle for engineering services and program management support. Commands including NAVSEA, NAVAIR, NAVWAR, NAVSUP, and the Marine Corps order through it. Thousands of companies hold a SeaPort-NxG contract, most of them small businesses. All the work happens at the task order level, every order is competed among holders, and set-asides are decided order by order. That makes winning a seat the easy part and winning task orders the real competition. New holders are added through periodic rolling admissions rather than a fixed pool.

Service Level Agreement

SLA
Contracts

Negotiated document spelling out the specific performance standards a contractor must meet (response times, uptime, throughput, quality thresholds), how they're measured, and the remedies, like credits or penalties, if they're missed. SLAs are usually built into the SOW or PWS on services contracts to make performance objectively enforceable.

Sources Sought Notice

SSN
Contracts

Market research notice posted on SAM.gov, under FAR 10.002, asking industry to describe its capability and interest in a potential upcoming requirement. Agencies use the responses to gauge competition, shape set-aside decisions, and pick an acquisition strategy. It's not a solicitation, and responding doesn't lead directly to an award.

Special Item Number

SIN
Contracts

A category code within a GSA Multiple Award Schedule that groups similar products, services, or solutions, such as IT professional services or cloud computing. Contractors must be awarded each SIN they want to sell under, and agencies often search and issue RFQs by SIN. When a company adds capabilities to its schedule, it's usually adding a new SIN, which requires its own proposal showing relevant experience and pricing.

Statement of Work

SOW
Contracts

Section of a solicitation or contract spelling out the specific tasks, deliverables, schedule, and standards a contractor must meet to perform the work. SOWs are more directive and task-based than Performance Work Statements, which describe the required outcome and leave the contractor to determine the method.

T

Task Order

TO
Contracts

Order for work placed against an existing IDIQ, GWAC, or BPA rather than issued as a standalone contract, specifying the scope, period of performance, and funding for that discrete piece of work. Under multiple-award vehicles, this is typically where the real price and technical competition happens, not at the base-contract stage.

Teaming Agreement

Contracts

Written agreement between a prime and one or more subcontractors (or between potential co-bidders) that defines roles, workshare, exclusivity, and terms for pursuing and performing a specific opportunity together. Distinct from an NDA or joint venture, it typically only becomes binding once the named prime wins the award.

Time and Materials

T&M
Contracts

Contract type under FAR 16.601 that pays negotiated hourly labor rates, covering wages, overhead, and profit, plus the cost of materials used. It suits work whose scope or duration can't be estimated accurately upfront, but it puts the least cost risk on the contractor and demands close government surveillance to control costs.

Transformation Twenty-One Total Technology Next Generation

T4NG
Contracts

The Department of Veterans Affairs' multiple-award IDIQ for IT services and modernization, run by VA's Technology Acquisition Center and open to other agencies. The original T4NG closed to new orders in mid-2026. Its successor, T4NG2, has a ceiling of about $60 billion over up to ten years and is now the main VA vehicle for IT services. It's held by a mix of large and small businesses, and VA's Veterans First rules give veteran-owned and service-disabled veteran-owned firms priority on many task orders.
