The Complete Guide to Government Contracting
Federal procurement is the largest marketplace in the world — over $700 billion annually. This guide walks you through every step from registration to award.
1. Determine If You're Ready
Before pursuing federal contracts, assess your business readiness:
- Track record — Most agencies want 2+ years in business with demonstrated past performance
- Financial stability — Government payment cycles are 30-90 days; ensure cash flow can sustain this
- Capacity — Can you deliver at the scale the government requires while maintaining quality?
- Compliance infrastructure — Federal contracts carry reporting, cybersecurity (CMMC/NIST 800-171), and accounting (DCAA) requirements
2. Get Registered
Registration is mandatory before you can bid on or receive any federal contract.
SAM.gov Registration
The System for Award Management (SAM.gov) is the single authoritative source. You need:
- UEI — Unique Entity Identifier (replaced DUNS in April 2022)
- CAGE Code — Commercial and Government Entity code, auto-assigned during SAM registration
- NAICS Codes — Select the North American Industry Classification System codes that match your capabilities
- Core Data — Business type, size, ownership, points of contact, banking information
Registration takes 7-10 business days and must be renewed annually. Start at SAM.gov.
Small Business Certifications
If eligible, certifications give you access to set-aside contracts reserved for small businesses:
- 8(a) Business Development — For socially and economically disadvantaged firms. 9-year program with sole-source authority up to $4.5M (services) or $7M (manufacturing)
- HUBZone — Historically Underutilized Business Zones. Must maintain 35% of employees in a HUBZone
- SDVOSB — Service-Disabled Veteran-Owned Small Business. Veteran must own 51%+ and control daily operations
- WOSB/EDWOSB — Women-Owned and Economically Disadvantaged Women-Owned. Self-certification or SBA certification

Understanding Solicitation Types
| Type | What It Means | Action Required |
|---|---|---|
| RFI | Request for Information — market research, no award | Respond to shape the requirement |
| Sources Sought | Agency looking for capable vendors | Submit capability statement |
| RFP | Request for Proposal — best value evaluation | Submit full technical + price proposal |
| RFQ | Request for Quotation — price-focused (usually simplified) | Submit pricing with brief technical |
| IFB | Invitation for Bid — sealed bidding, lowest price wins | Submit sealed price bid |
4. Write a Winning Proposal
Government proposals are evaluated against stated criteria in the solicitation. The three universal principles:
- Compliance first — Follow every instruction in Section L (Instructions) exactly. Non-compliant proposals are eliminated before evaluation
- Address every evaluation factor — Section M lists exactly what evaluators will score. Mirror this structure
- Prove it with evidence — Don't claim "extensive experience." Instead: "Delivered 47 cybersecurity assessments across 12 DoD installations over 5 years, achieving 100% on-time delivery"
Proposal Structure
- Volume I: Technical Approach — How you'll accomplish the work. Include staffing plan, methodology, schedule, risk mitigation
- Volume II: Past Performance — 3-5 relevant contracts with scope, value, agency, period, and performance outcomes
- Volume III: Price/Cost — Detailed pricing by CLIN. For cost-reimbursement: labor categories, rates, ODCs, fee structure
- Volume IV: Administrative — Reps & certs, teaming agreements, subcontracting plan (if >$750K)

5. After Award
Winning the contract is the beginning, not the end:
- Kickoff meeting — Align with the Contracting Officer (CO) and Contracting Officer's Representative (COR) on deliverables, reporting, and communication
- Invoice correctly — Use WAWF (Wide Area Workflow) for DoD, or IPP (Invoice Processing Platform) for civilian agencies
- Track performance — Your CPARS (Contractor Performance Assessment Reporting System) rating follows you. One bad rating can disqualify you from future bids
- Manage modifications — Scope changes, period extensions, and funding adjustments flow through the CO via contract modifications
