Small Business Guide to Breaking into Government Contracting
For small and midsize businesses (SMBs), government contracting isn’t just another business development channel — it’s access to the largest single customer in the world: the U.S. federal government.
Every year, the federal government purchases a vast array of products and services, creating a contracting marketplace that ranges from $700 billion to $800 billion annually. These opportunities span industries from construction, IT, and engineering to catering, logistics, consulting, and even the sourcing of office supplies.
The best part? The federal government is not only a massive buyer but also legally obligated to ensure that small businesses participate in this market. By law, a significant percentage of all contracting dollars must flow to small businesses. 23% of prime contract dollars and 30% of subcontracting dollars must go to small businesses. In fact, the government actively encourages SMBs to compete for and win contracts, offering specialized programs, resources, and procurement advantages.
Types of Contractors
Prime Contractors: Bid directly on opportunities issued by government agencies. Winning primes must manage full compliance, reporting, and delivery obligations.
Subcontractors: Support prime contractors by providing niche products or services. Many small businesses begin here, as subcontracting offers lower barriers to entry and provides crucial past performance experience.
Targeted Small Business Set-Asides
Beyond the general small business spending goals, the federal government sets specific contracting targets for different categories of small businesses.
Women-Owned Small Businesses (WOSB): 51% owned and controlled by women who are U.S. citizens. Target of 5% of all federal contracting dollars.
Minority-Owned Businesses: Supported by the 8(a) Business Development Program, which offers mentorship, exclusive opportunities, and developmental assistance for socially/economically disadvantaged owners. Provides mentoring and exclusive opportunities. 5% of federal contracts are reserved for this type of business.
Service-Disabled Veteran-Owned Small Businesses (SDVOSB): 51% owned and managed by service-disabled veterans. Target of 5% of federal contracting dollars.
HUBZone-certified businesses: Target of 3% of federal contracting dollars.
These designations grant access to set-aside contracts — procurements reserved exclusively for businesses with these certifications. For eligible SMBs, these contracts are golden opportunities to compete on a level playing field.
Entry Requirements to qualify to Small Business Set-Asides
To pursue federal government contracts under the set-asides, small businesses must meet several foundational requirements:
1. Qualify as a Small Business: Not every “small” company qualifies as a small business for federal contracting. The Small Business Administration (SBA) defines eligibility using size standards tied to your industry’s NAICS (North American Industry Classification System) code. General thresholds to qualify as a small business entail having less than 500 employees for manufacturers and less than $7.5M in average annual receipts for non-manufacturers. Use the SBA’s Size Standards Tool to confirm eligibility.
2. Register in the System for Award Management (SAM.gov): Registering your business in SAM, the federal government’s database for contractors, is mandatory for participating in government contracting. Government agencies use this database exclusively to find potential contractors. This registration allows you to certify your business's eligibility for contracts reserved for small businesses, and also to indicate if your business qualifies for SBA contracting programs (e.g., as disadvantaged, women-owned, veteran-owned, or located in an underutilized area). Your SAM profile acts like a résumé, so it's crucial to use accurate and descriptive terms so contracting officials can easily find your business.
3. Obtain a Unique Entity Identifier (UEI): Before bidding on government proposals, you must obtain a UEI, which is a unique 12-character alpha-numeric value. This identifier is assigned automatically when you register with SAM.gov and has replaced the older DUNS number. If your entity is already registered with SAM, your UEI has already been assigned.
4. Match Your NAICS Codes: You need to match your products and services to a North American Industry Classification System (NAICS) code, which classifies businesses based on their specific offerings. A business typically has a primary NAICS code but can have multiple if it provides diverse products and services. You can find your NAICS code on the U.S. Census Bureau website.
Compliance and Regulations
Participating in government contracting requires adherence to all applicable laws and regulations. Compliance is non-negotiable in the GovCon space, and depending on size and scope of work, compliance requirements can vary. Typically, SMBs must adhere to:
Federal Acquisition Regulations (FAR): The primary body of rules governing federal procurement.
13 CFR 125: Specifics on small business programs in government contracting.
DCAA (Defense Contract Audit Agency): Audits contractors for compliance with accounting, billing, and timekeeping rules.
DCMA (Defense Contract Management Agency): Oversees performance and contract management.
Cybersecurity Requirements: For Department of Defense (DoD) contracts, firms must meet the Cybersecurity Maturity Model Certification (CMMC).
Failure to maintain any of these compliance requirements can result in fines, disqualification, or loss of contracts. For small businesses, establishing robust compliance systems early on is crucial.
Visibility and Subcontracting Opportunities
Holding a certification doesn’t just unlock set-asides. It also boosts visibility with prime contractors (large businesses that win federal contracts directly). Many prime contractors are required to include small and certified businesses in their bids, which translate into consistent subcontracting opportunities.
This pathway — starting as a subcontractor, building a track record, and then moving up to prime contractor status — is a proven strategy for SMEs entering GovCon. It allows businesses to demonstrate their capabilities, gain past performance credentials, and expand networks while reducing early-stage risks.
Strategic Growth and Credibility
Government contracts are more than just revenue streams. They’re powerful credibility builders. Landing even one federal contract signals to the market that your company can meet the highest standards of compliance, quality, and reliability. Over time, persistence and patience in the GovCon world can unlock game-changing contracts that fuel long-term growth.
The Small Business Administration (SBA) also provides robust resources to small businesses. Business Development Support Programs like the SBA's 8(a) Business Development program are specifically designed to assist eligible socially and economically disadvantaged individuals. This program provides one-on-one counseling, training workshops, matchmaking opportunities with federal buyers, and other management and technical guidance, alongside exclusive bidding opportunities. Government agencies often have dedicated offices (e.g., Offices of Small and Disadvantaged Business Utilization) focused on maximizing opportunities for small businesses, and proper certification is key to leveraging these resources. This support includes
Learning Platforms & Guides covering everything from compliance to proposal writing.
Local Support through Small Business Development Centers (SBDCs) and Women’s Business Centers.
Mentorship Programs, especially under 8(a), where businesses are paired with established mentors.
Accelerator programs with local universities such as the George Mason University-sponsored Virginia APEX Accelerator.
Where to Find Opportunities
Small businesses can access federal contracts through multiple channels:
SAM.gov: This is a primary platform where most agencies post upcoming solicitations and opportunities. You can search SAM.gov for active contracts that align with your business capabilities.
SBA’s Small Business Search (SBS): In addition to SAM.gov, you can explore the SBA's SBS, previously known as the Dynamic Small Business Search (DSBS), which allows you to find subcontracting opportunities with larger companies. Many federal contracts require large businesses to work with small businesses, making DSBS a valuable tool for entering the market
Agency Portals: Many federal agencies maintain their own websites or portals where they offer contract forecasts and procurement pages. These can provide early notice of opportunities before they are listed on general platforms.
Networking & Events: Attending GovCon-related events, industry days, and outreach sessions is another valuable way to perform market research and directly meet agency buyers. Groups like NCMA and NAPEX host conferences, workshops, training, and networking events.
Subcontracting with Prime Contractors: A common strategy for small businesses to enter government contracts is by seeking out subcontracting partnerships with established prime contractors. This allows your firm to gain valuable experience and establish a track record while potentially navigating complex compliance requirements with support. Many federal contracts require large prime contractors to include small businesses in their bids
Tips for Success in Government Contracting
Breaking into federal contracting takes preparation, patience, and persistence—but the opportunities are vast. To set yourself up for success:
Research smartly and focus on agencies that align with your strengths.
Pursue certifications like 8(a), HUBZone, WOSB, or SDVOSB to access set-aside contracts.
Network actively with contracting officers, primes, and industry groups to build relationships.
Start as a subcontractor to gain experience and credibility.
Market your story with a strong capability statement and clear messaging.
Maintain compliance with FAR, CAS, and (if applicable) DCAA, DCMA, and CMMC requirements.
Seek mentorship through the SBA’s Mentor-Protégé Program.
Stay patient and resilient—federal contracting is competitive, but persistence pays off.
By combining strategic research, certifications, compliance, and strong systems like ERP solutions, small businesses can move from first-time subcontractors to trusted prime contractors, building sustainable growth in the federal marketplace.
Scaling in Government Contracting: Why ERP Systems Like SumX Matter
Breaking into government contracting is just the first hurdle—scaling sustainably is where the real challenge begins. As you grow, you’ll need to manage strict accounting standards, ensuring FAR, CAS and DCAA compliance through project-based accounting and allocation of indirect costs. Approval chains will get more complex, requiring layered sign-offs, audit-trails, and detailed compliance reporting. Cash flow monitoring becomes a constant requirement, where tools like “Pay When Paid” can be essential to properly manage subcontractor payment flow. If you have Joint Venture initiatives or multiple entities, you’ll also need advanced multi-company and inter-company processes to stay on top of operations. And when it comes to expenses and payables, manual processes won’t suffice—OCR-driven data capture and automated workflows are essential for reducing administrative work while maintaining high accuracy.
