State laws usually set three tiers: small purchases with no formal competition, a middle range that needs quotes, and larger purchases that need formal sealed bids.
Examples
- Indiana public works: quotes are invited for projects between $50,000 and $300,000; formal bids are required at $300,000 or more (IC 36-1-12).
- Iowa vertical public improvements (buildings): for bids on or after January 1, 2025, counties use competitive quotes above $153,000 and formal bids at $206,000 or more. These thresholds are adjusted periodically.
Why quotes matter for small businesses
Quote requests often go only to vendors the county already knows, and aren't always advertised. Get on the county's vendor list (how to register) and introduce yourself to the purchasing office, so you're invited.
