GovCon in Plain English: The 80/20 Guide to Government Contracting

The government is the biggest customer on Earth, and it is legally required to shop in public. Almost everything about government contracting follows from that one sentence: agencies must announce what they want to buy, must let qualified businesses compete, and must pay their bills.

Money flows downhill through five gates. Every feature of the system — portals, NAICS codes, set-asides, deadlines — exists at one of these gates:

Budget — Congress (or a state legislature / city council) appropriates money to agencies. Use it or lose it.

Need — an agency needs something (cleaning, software, a bridge) and writes requirements.

Announce — by law, most purchases above small thresholds must be posted publicly for competition. This is the solicitation.

Compete — businesses submit bids or proposals by a hard deadline. Late equals automatically rejected.

Award & pay — the agency evaluates, awards a contract, the work happens, and the government pays (slowly but reliably).

The 80/20 insight: government buyers are not shopping for the cheapest or the flashiest option. They are protecting themselves. Every rule exists so no one can accuse them of favoritism or waste. A vendor who makes the buyer feel safe and compliant beats a vendor who is merely good.

Scale, roughly: the US federal government signs about $750 billion in contracts a year, and roughly a quarter of those dollars go to small businesses. State and local governments combined buy on a similar or larger scale — spread across thousands of separate portals. That fragmentation is exactly the problem a single dashboard solves.

Same logic, different rituals. A serious contracting operation covers both, but most businesses start in one.

Where opportunities are posted

• Federal: one front door, SAM.gov.


• State & local ("SLED"): thousands of portals — state eProcurement sites, city pages, BidNet, county PDFs.

The rulebook

• Federal: the FAR (Federal Acquisition Regulation) — dense but uniform.


• State & local: each state or city has its own rules, generally simpler.

Typical size and speed

• Federal: bigger contracts, longer terms, more paperwork.


• State & local: smaller, faster, more frequent awards.

Registration

• Federal: one SAM.gov registration (with your UEI and CAGE code) covers everything.


• State & local: register separately per portal — annoying, but free.

Best for beginners: state and local is usually the on-ramp. Smaller bidder pools and simpler paperwork mean janitorial, grounds, and small-works contracts are winnable early — and those wins become the past performance that later unlocks federal work.

Before anyone can win a federal contract, the government needs to know they exist. Three identifiers, one registration:

• SAM.gov — the System for Award Management. One website that is simultaneously the federal vendor registry and the federal opportunity board. Registering as an entity is free and takes 2–6 weeks (validation is the slow part).
• UEI — Unique Entity ID. A 12-character ID issued during SAM registration. It replaced the old DUNS number and, as far as the government is concerned, it *is* your company.
• CAGE code — a 5-character code assigned after registration, used mostly by defense agencies.

Scam radar: an entire cottage industry charges $500–$3,000 to "register you in SAM." Registration is free. Legitimate consultants add value on strategy and proposals, not on filling in a free form. State and local portals each have their own free (tedious) vendor registration — a real reason to watch them all from one place.

NAICS is the six-digit industry code system, and it quietly controls everything: what you match, what you can bid, and whether you count as small.

• Every solicitation is tagged with a NAICS code (for example 561720 janitorial, 236220 commercial construction, 541512 computer systems design).
• Businesses claim the codes that describe what they do — a primary code plus any genuine secondaries.
• Each code has its own size standard, set by the SBA: either a revenue cap (janitorial is roughly $22M average annual receipts) or an employee cap (many manufacturing codes: 500–1,500 employees). "Small business" is not one definition — a company can be small under one code and large under another.

The trap: agencies sometimes tag solicitations with sloppy NAICS codes — a supplies purchase wearing an IT-services code. A code match is a lead, not a verdict. Read the title and description before deciding it fits.

Not every posting is a bid. Knowing which is which saves you from wasting a week on the wrong thing:

• Sources Sought / RFI — market research. The agency is asking "who can do this?" before writing the real solicitation. Respond: it is free, short, and can shape the requirement or trigger a set-aside. The insider's secret weapon.
• Presolicitation — a heads-up that a solicitation is coming. Prepare; do not submit yet.
• RFQ (Request for Quote) — a simple purchase; send a price. Respond if you can be competitive. Fast.
• IFB (Invitation for Bid) — sealed bidding; lowest responsive, responsible bid wins. Common in construction and state/local. A pure price game with pass/fail compliance.
• RFP (Request for Proposal) — the full ritual: a written proposal evaluated on approach, experience, and price. The main event; pick your battles.
• Combined Synopsis/Solicitation — announcement plus solicitation in one, for simpler commercial buys. Common on SAM.gov.
• Award notice — already won by someone. Do not respond, but mine it for competitor intelligence.

Two universal mechanics: amendments (agencies revise solicitations constantly — you must acknowledge them in your bid) and the Q&A window (a period where every vendor question is answered publicly to all bidders).

The government deliberately reserves a share of its spending for small and disadvantaged businesses. The statutory goal: at least 23% of federal prime contract dollars to small businesses. A set-aside restricts competition to a category of business:

• Total / Partial Small Business — any business under the NAICS size standard. The most common set-aside.
• 8(a) — socially/economically disadvantaged owners, SBA-certified, 9-year program. The strongest: agencies can sole-source up to ~$4.5M ($7.5M manufacturing).
• WOSB / EDWOSB — women-owned small business (51%+ owned and controlled). Set-asides in designated industries.
• SDVOSB / VOSB — service-disabled / veteran-owned. SDVOSB is powerful at the VA's "Veterans First" rule.
• HUBZone — business in a designated underutilized zone with 35% of employees living there. Price-preference perks.

Two things worth knowing: certifications stack (a woman-veteran-owned 8(a) firm in a HUBZone can chase four lanes at once), and eligibility is binary — a set-aside you do not qualify for is simply invisible to you. Federal certs run through the SBA; states run parallel MBE/WBE/DBE programs with separate paperwork.

From "found it" to "paid," in the order you actually live it:

Find — the daily scan across portals.

Bid / no-bid — the discipline that separates pros from burnouts. Can you actually do this, price it, meet the pass/fail requirements, and beat the incumbent?

Engage — attend the site visit / pre-bid conference (sometimes mandatory), submit questions during Q&A, watch for amendments.

Write — typically three parts: technical approach (how you'll do the work), past performance (proof you've done similar), and price. Follow the instructions (federal: Section L) with obsessive literalism.

Submit — before the deadline, in the required channel. One minute late is dead. No exceptions.

Wait & win/lose — evaluation takes weeks to months. Losers can request a debrief — free intelligence on why.

Perform & get paid — invoices are net-30 under the federal Prompt Payment Act; states vary but pay reliably.

The compliance gate: most first bids lose on compliance, not quality — missed forms, wrong format, unanswered requirements. Evaluators look for reasons to throw bids out; it shrinks their workload. "Compliant, complete, on time" beats "brilliant but sloppy" every time.

Two philosophies, and one chicken-and-egg problem every new contractor hits.

LPTA vs. Best Value

• LPTA (Lowest Price Technically Acceptable) — pass the technical bar, then cheapest wins. Common for commodity services. New firms can win here on hunger.


• Best Value / Tradeoff — the agency may pay more for a stronger proposal. Factors (technical, past performance, price) are weighted and stated in the solicitation (Section M federally). Experience matters more.

The past performance problem: agencies want proof you've done it before, but you can't get proof without a first win. Four standard ways in:

Start small and local — city/county contracts with lighter requirements, where "local and hungry" carries weight.

Subcontract first — work under a prime; their win becomes your past performance.

Use commercial experience — many solicitations accept relevant non-government work.

Team up — joint ventures and the SBA Mentor-Protégé program let you borrow a partner's credentials.

No one can honestly promise you a win. The credible framing: you can't win the ones you never saw, and you can't win with a non-compliant bid.

Government money expires. That single fact creates the industry's seasons.

• Federal fiscal year: October 1 → September 30. Unspent appropriations mostly vanish at year end.
• Q4 (July–September) is the gold rush. Agencies race to obligate leftover budgets — August and September see a flood of awards, especially smaller, faster buys. Being registered and visible *before* Q4 is the whole game.
• Q1 (Oct–Dec) is slow — new budgets aren't fully released, and shutdown drama can freeze things.
• Most states run July 1 → June 30 fiscal years, so state buying surges in spring (April–June).

Between federal Q4 and state Q4, there is a spend-surge somewhere most of the year. "Fiscal year end" is the most reliable, verifiable urgency in all of government contracting.

Government contracting is a tribe, and the fastest way to be taken seriously is to use its vocabulary correctly. Say the word on the left, not the phrase on the right:

• solicitation, opportunity, bid — not "job posting," "listing," or "gig."
• agency, contracting officer (CO) — not "the client" or "the government guy."
• response deadline, closing date — not "expiry" or "due by-ish."
• set-aside, sole source — not "special program" or "reserved deal."
• past performance — not "experience" or "portfolio."
• incumbent — not "the competition."
• period of performance (PoP) — not "contract length."
• prime / subcontractor — not "main contractor / helper."

The one rule above all: in an industry built on compliance, your credibility is the product. Never promise a win, never overstate your certifications, and never cite a contract detail you haven't verified against the source.
