Frequently Asked Questions โ Government Contracting by Industry
IT and technology is the largest single industry by dollar value โ the federal government spends over $90 billion annually on IT. Construction is second, with over $150 billion across federal, state, and local governments. Professional services and consulting represent another $60 billion federally. In terms of contract count (not value), cleaning/janitorial and grounds maintenance generate the highest volume of individual solicitations because every federal building and facility needs recurring service contracts.
Almost any legitimate U.S. business can pursue government contracts. The main requirements are: an active SAM.gov registration (for federal work), a Tax Identification Number, and compliance with applicable regulations for your industry. Certain restricted areas (like classified national security work) require security clearances. Businesses owned by foreign nationals or with certain past legal issues may face restrictions. Otherwise, companies of any size โ including sole proprietors โ can and do win government contracts.
Landscaping, cleaning, and janitorial services consistently have the lowest barriers to entry. These sectors require minimal specialized certifications beyond standard business licensing, have high small business set-aside rates, and offer many small contracts accessible to new entrants. Trucking is also accessible for operators already meeting commercial freight standards. IT is highly accessible for technology firms if they understand CMMC requirements. The 'easiest' industry is ultimately the one where your existing capabilities, licenses, and equipment already meet government requirements.
SAM.gov registration is required for all federal contracts. Beyond that, certifications depend on industry: electrical and plumbing work requires state contractor licenses; food service requires food safety certifications; security work requires state guard licenses. Separately, small business certifications (8(a), SDVOSB, HUBZone, WOSB) are optional but give you access to set-aside competitions with fewer competitors. These certifications are managed by the SBA and are free to apply for.
Most small businesses take 6โ18 months from SAM.gov registration to their first award. The timeline depends on your industry (cleaning and landscaping can move faster than IT or consulting), whether you have relevant past performance, and how actively you're pursuing opportunities. Starting with state and local government contracts typically yields faster first wins than federal work. Subcontracting to an established prime is often the fastest path โ you can start generating revenue and building past performance within weeks of registering.
