Federal Contracts 101

Everything a new market entrant needs to understand about how the U.S. government buys services — procurement types, contract vehicles, set-asides, the role of the Contracting Officer, and how companies win federal work.

By Pedro Rubio · Former GSA Contracting Officer · Updated April 2025

Section 01

How the Federal Government Buys

The federal government spent over $750 billion on goods and services in the most recent fiscal year. Unlike commercial procurement, federal buying is governed by law — primarily the Federal Acquisition Regulation (FAR).

FAR defines how RFPs are written, how bids are evaluated, how contracts are structured, and what rights contractors have. Understanding FAR basics is prerequisite to any federal market strategy.

Key fact: Federal agencies are required by law to follow procurement rules. This creates predictability — the same process, the same evaluation criteria, the same award timeline framework. Once you understand the system, you can compete in it.

Section 02

Types of Contract Vehicles

Federal contracts come in several forms. Understanding which vehicle applies to your services determines your go-to-market strategy.

IDIQ

Indefinite Delivery / Indefinite Quantity. Master agreement for task orders over time. GSA Schedules, SEWP, and OASIS+ are all IDIQs.

BPA

Blanket Purchase Agreement. Agency-specific agreements under a GSA Schedule for recurring purchases. Offer predictable recurring revenue.

Firm Fixed Price

Contractor delivers defined scope at a fixed price. Common for well-defined, measurable services with clear deliverables.

Time & Materials

Government pays for labor hours at a fixed rate plus materials. The standard structure for IT professional services on GSA Schedules.

Cost-Plus

Contractor reimbursed for allowable costs plus a fee. Common for R&D, complex defense work, and early-stage program development.

Section 03

The Role of the Contracting Officer

The Contracting Officer (CO) is the only person with legal authority to bind the U.S. government to a contract. COs sign contracts, negotiate terms, and make award decisions. Their authority comes from a warrant issued by their agency.

Contract Specialists (CS) conduct day-to-day evaluation of offers — reviewing proposals, drafting clarification requests, and preparing award recommendations for the CO's signature.

Pedro Rubio spent years in both roles — as CS and CO at GSA, IRS, DoD, and DOI. That inside perspective is the core of Blackfyre's competitive advantage: knowing exactly what evaluators are looking for and how they think.

Section 04

Set-Asides and Small Business Programs

The federal government reserves a portion of its spending for small and disadvantaged businesses. These set-aside programs can significantly improve your odds of award — if you qualify.

8(a)

SBA program for socially and economically disadvantaged business owners. Eligible for sole-source awards up to $4.5M for services, $7M for manufacturing.

SDVOSB

Service-Disabled Veteran-Owned Small Business. VA and DoD preference in set-asides. Strong pipeline for defense and veterans health administration work.

WOSB

Women-Owned Small Business. Set-aside authority in designated NAICS codes where women-owned businesses are underrepresented.

HUBZone

Preference for businesses in Historically Underutilized Business Zones. Requires principal office location and workforce in a designated HUBZone.

Small Business

The broadest category. Most agencies have goals of 23%+ small business spend. Determined by NAICS code size standards.

Section 05

SAM.gov and Registration Requirements

SAM.gov (System for Award Management) is the federal government's primary vendor database. Every company pursuing federal contracts must register and maintain an active SAM.gov record. Registration is free.

Requirements include:

  • Unique Entity Identifier (UEI) — replaced the DUNS number in 2022
  • Business name, address, and legal structure
  • NAICS codes describing your primary services
  • Banking information for Electronic Funds Transfer (EFT)
  • Certifications and representations
  • Annual renewal (registration expires yearly)

Expired SAM.gov registration disqualifies you from award. This is one of the most avoidable reasons companies miss out on contracts they've earned.

Section 06

The Procurement Process: RFP to Award

Federal procurement follows a defined sequence. Understanding each phase gives you the ability to engage strategically — not just respond reactively.

1
Agency identifies need

Program office determines requirement and funding. Acquisition strategy is developed and procurement method selected.

2
Sources Sought / RFI (optional)

Agency may issue a market research notice to gauge interest and capability before finalizing requirements.

3
RFP or RFQ issued

Posted on SAM.gov (open competition) or eBuy (GSA Schedule task orders). Proposal deadline specified.

4
Proposals submitted

Offerors submit by the deadline. Late submissions are generally rejected without exception.

5
Evaluation by CO/CS

Proposals scored against stated evaluation criteria — typically technical capability, past performance, and price.

6
Discussions or clarifications

CO may request clarifications or open discussions before award. Not all procurements include this phase.

7
Award decision and notification

CO makes award. Unsuccessful offerors are notified. Debriefs available upon request.

Section 07

GSA Schedules vs. Full and Open Competition

Full and open competition requires a complete FAR acquisition process — market research, solicitation, evaluation, award. It can take months or years from requirement to contract.

GSA Schedules are pre-competed: pricing and terms are already established. Agencies can issue a task order and award in days without running a full competition. This speed is the primary reason agencies prefer the Schedule for most service acquisitions.

For most services under $10M, GSA is the preferred procurement method. Having a GSA Schedule is table stakes for federal market entry.

Bottom line: Without a GSA Schedule, you're competing for the minority of federal opportunities that go through open competition. With one, you have access to the full $45B+ Schedule market.

Section 08

How to Start Winning Federal Work

A practical roadmap for companies entering the federal market:

1
Get SAM.gov active and current

Register at SAM.gov, obtain your UEI, and set a calendar reminder to renew annually. No exceptions.

2
Identify target NAICS codes and agencies

Use USASpending.gov and FPDS to find agencies that buy what you sell. Size the opportunity before investing.

3
Get a GSA Schedule

If selling services, a GSA Schedule is the most effective vehicle. It pre-qualifies you and opens eBuy task orders that never reach the open market.

4
Monitor eBuy and SAM.gov

Set up saved searches for relevant NAICS codes and SINs. Respond to every relevant RFI to build visibility.

5
Build past performance

Subcontract to a prime if needed. Federal past performance is the most valuable asset you can build in this market.

6
Engage agencies pre-RFP

Most awards go to vendors with pre-existing relationships. Respond to sources sought. Attend industry days. Get known before the solicitation drops.

FAQ

Frequently Asked Questions

What is the FAR? +
The Federal Acquisition Regulation is the primary rulebook for federal procurement. Codified at 48 CFR, it covers solicitation writing, contract structure, and contractor rights. Part 8 covers the GSA Schedule ordering process.
Do I need a DUNS number to get a federal contract? +
The DUNS system was replaced by the Unique Entity Identifier (UEI) in 2022. You register for a UEI through SAM.gov — it's free and required for any federal contracting.
What is the difference between a prime contractor and a subcontractor? +
A prime contractor has a direct contract with the government. A subcontractor is hired by the prime to perform part of the work. Subcontracting is a legitimate path to federal revenue and past performance for companies without established federal history.
How does the government find vendors? +
Primarily through SAM.gov (where all solicitations are posted), eBuy (for GSA Schedule task orders), and existing relationships. Agencies often prefer vendors they've worked with before or who responded to prior RFIs.
Is federal contracting worth it for small companies? +
Yes — if approached strategically. The federal market is enormous, pays reliably, and can create long-term recurring revenue. Most companies need 12–18 months from initial effort to first award.
