Introduction to US Federal Procurement
The United States federal government is the single largest buyer of goods and services in the world, spending over $700 billion annually on everything from advanced weapons systems and IT infrastructure to office supplies and janitorial services. For businesses of all sizes, federal contracting represents an enormous and stable market — but one governed by a complex regulatory framework that demands careful navigation.
Unlike commercial procurement, federal contracting is governed primarily by the Federal Acquisition Regulation (FAR), a comprehensive set of rules that standardises how agencies buy goods and services. Understanding the FAR, the procurement ecosystem, and the various contract vehicles available is essential for any company seeking to enter or grow in this market.
Getting Started: SAM.gov Registration
The System for Award Management (SAM.gov) is the gateway to federal contracting. Every business seeking to do business with the federal government must register in SAM.gov. Registration is free and requires your company legal name, address, banking information, NAICS codes (industry classification), and a Unique Entity Identifier (UEI), which replaced the DUNS number in 2022.
SAM.gov also serves as the primary portal for finding contract opportunities. The system consolidates what was formerly FedBizOpps (FBO) and several other procurement databases. Suppliers can search for active solicitations, set up saved searches with email alerts, and track contract award data. Registration must be renewed annually to maintain active status.
Key Data Systems
Beyond SAM.gov, several federal data systems provide critical market intelligence. The Federal Procurement Data System (FPDS) contains detailed information on every federal contract action, allowing you to research which agencies buy your products or services, who your competitors are, and what prices the government has paid historically. USAspending.gov provides broader spending data and visualisations. GovWin (by Deltek) and other commercial databases offer enhanced analytics and opportunity tracking for serious federal contractors.
The Federal Acquisition Regulation (FAR)
The FAR is the primary regulation governing federal procurement. It is organised into 53 parts covering everything from acquisition planning and competition requirements to contract types, pricing, and administration. Key parts include: FAR Part 12 (commercial item acquisition), FAR Part 13 (simplified acquisition procedures for purchases under $250,000), FAR Part 15 (contracting by negotiation — the basis for most large competitive procurements), and FAR Part 19 (small business programmes).
Agency-specific supplements add additional requirements. The most significant is the Defense Federal Acquisition Regulation Supplement (DFARS), which applies to Department of Defense procurements and adds requirements around cybersecurity (CMMC), cost accounting, and defence-specific clauses. Other agencies have their own supplements (e.g., GSAM for GSA, AIDAR for USAID).
Contract Types
Federal contracts come in several types, each allocating risk differently between the government and the contractor:
Firm-Fixed-Price (FFP): The contractor agrees to deliver the specified work for a fixed price, regardless of actual costs. The contractor bears maximum cost risk but also retains any savings. FFP is the government preferred contract type for well-defined requirements.
Time-and-Materials (T&M): The contractor is paid at negotiated hourly rates plus the cost of materials. T&M is used when the scope of work cannot be precisely defined. The government bears more cost risk, so T&M contracts typically include ceiling prices and require close government oversight.
Cost-Plus-Fixed-Fee (CPFF): The government reimburses the contractor allowable costs plus a negotiated fixed fee. CPFF is used for research, development, and other efforts where costs are highly uncertain. Contractors must have an adequate accounting system and comply with Cost Accounting Standards (CAS).
Indefinite Delivery/Indefinite Quantity (IDIQ): These are umbrella contracts that establish terms and conditions for an indefinite quantity of goods or services over a specified period. The government places individual task orders or delivery orders against the IDIQ as needs arise. IDIQs are the basis for many major contract vehicles.
Contract Vehicles: GWACs, BPAs, IDIQs, and MACs
Contract vehicles are pre-competed agreements that agencies use to streamline procurement. Understanding these vehicles is critical to market access:
Government-Wide Acquisition Contracts (GWACs): These are IDIQ contracts for IT products and services that any federal agency can use. Major GWACs include Alliant 2 (large business IT services), 8(a) STARS III (8(a) small business IT), VETS 2 (veteran-owned small business IT), and Polaris (small business IT). Getting onto a GWAC provides access to a broad customer base.
Blanket Purchase Agreements (BPAs): These are simplified arrangements for recurring purchases. BPAs establish pricing and terms, and the government places individual orders as needed. They are commonly used for commercial products and services below the simplified acquisition threshold.
Multiple Award Contracts (MACs): Many IDIQ contracts are awarded to multiple contractors, creating a pool of approved suppliers who then compete for individual task orders. This approach combines the efficiency of pre-competition with ongoing competitive tension at the task order level.
The GSA Schedule (MAS)
The GSA Multiple Award Schedule (MAS) — formerly known as the GSA Schedule or Federal Supply Schedule — is one of the most important contract vehicles for commercial suppliers. It is a long-term government-wide contract that allows federal, state, and local agencies to purchase commercial products and services at pre-negotiated prices.
Getting onto the GSA Schedule involves a detailed application through GSA eOffer system, including disclosure of commercial pricing, past performance references, and compliance with Trade Agreements Act (TAA) requirements for product country of origin. Once awarded, schedule holders can receive orders from any agency, making it one of the broadest market access tools available.
Acquisition Planning and Market Research
Federal procurements follow a structured lifecycle. Acquisition planning begins when an agency identifies a requirement. The contracting officer conducts market research — often including Requests for Information (RFIs) and industry days — to understand available solutions and the supplier landscape. This pre-solicitation phase is critical for contractors: engaging early allows you to shape requirements, demonstrate capabilities, and build relationships with the contracting officer and programme office before the formal competition begins.
Sources Sought notices and RFIs are published on SAM.gov and signal upcoming procurement opportunities. Responding thoughtfully to these pre-solicitation notices is one of the most effective business development activities in federal contracting.
Proposal Writing
Federal proposals are evaluated against specific criteria stated in the solicitation (typically in Section M). Common evaluation factors include technical approach, management approach, past performance, staffing, and price. Proposals must be compliant with all solicitation requirements — non-compliant proposals are typically eliminated without evaluation.
Winning proposals clearly articulate a solution that addresses the government stated needs, demonstrate relevant past performance with specific examples and metrics, present a qualified and available team, and offer fair and reasonable pricing. The most common mistake is writing generic marketing material rather than specific, evidence-based responses to the evaluation criteria.
For larger procurements, consider investing in professional proposal support — capture management, proposal management, and technical writing specialists who understand federal evaluation processes can significantly improve win rates.
Building Your Federal Business
Success in federal contracting is a long-term investment. Start by identifying your target agencies and understanding their missions and procurement patterns through FPDS research. Register in SAM.gov and obtain relevant certifications (small business, veteran-owned, etc.). Pursue subcontracting opportunities with established prime contractors to build federal past performance. Consider the GSA Schedule as an early market access vehicle. Attend industry days and respond to RFIs to build agency relationships. And develop your internal infrastructure — accounting systems, security clearances, compliance programmes — to meet the unique requirements of federal work.
