City of Boulder (vendor guide, read 2026-10-16): up to $9,999, departments compare quotes; $10,000 to $99,999, at least three informal bids; $100,000 and over, a formal bid. Vendors send a W-9 and a vendor form before any payment, and the city expects vendor web experiences to meet WCAG A and AA. The city is tax-exempt, and its guide asks bids to allow for that.
Boulder County (procurement page, read 2026-10-16): no specific rules apply to no-bid purchases below $10,000, and its bidding rules start at the $10,000 level. Complete at $9,850 is $149 under the City's $9,999 line, so one month of care on the same purchase order would cross it. We count the build plus 12 months of care and ask the buyer's office before we quote.
Boulder County counts (BLS, 2025 annual average, county-wide, not just the city): 1,026 law, accounting, architecture, investment and insurance offices; 408 non-physician health practices; 250 fitness, recreation, youth and arts businesses.
