Frequently asked questions
How much does the federal government spend on it services in Illinois?
Since Oct 2024, agencies obligated $1.1B across 1,428 IT services contracts performed in Illinois (NAICS 541512, 541511, 541519), an average of $764K per award. The Department of Defense is the largest buyer.
Where are it services bids posted in Illinois?
Federal opportunities performed in Illinois are posted on SAM.gov (filter by place of performance). State-level work is posted on BidBuy, and counties, cities, and school districts run their own portals — register with the largest ones in your service area.
Do I need to register with the state of Illinois to bid?
For Illinois state agency contracts, yes — register as a vendor on BidBuy. Federal contracts performed in Illinois only require SAM.gov registration, though state small-business certifications can still help with subcontracting.
Do I need a GSA Schedule to win government IT work?
No — plenty of IT work is solicited on the open market via SAM.gov, and agencies also buy through small business set-asides. A GSA MAS contract helps once you have past performance, but it is not a prerequisite.
What is CMMC and when does it apply?
Cybersecurity Maturity Model Certification applies to DoD contracts involving Federal Contract Information or Controlled Unclassified Information. Many DoD solicitations now require at least CMMC Level 1 self-assessment; Level 2 requires third-party assessment for CUI.
