Indiana Government Contracts — Procurement Guide

Indiana vendors register through the IDOA Vendor Portal. Once registered, you receive notifications for solicitations matching your commodity codes. Indiana also participates in the Shared Services initiative, where multiple agencies coordinate procurement to reduce duplicate efforts.

Indiana requires formal competitive sealed bids for purchases over $150,000. Informal competitive quotes are required for purchases between $25,000 and $150,000. Small purchases under $25,000 may be made with minimal competition. Construction follows separate public works bidding requirements.

Indiana has a reciprocal preference law that applies Indiana preferences against states that have preferences against Indiana vendors. The practical effect is limited but relevant if you compete against out-of-state vendors. There is no general preference for in-state vendors on most state contracts.

Indiana DOT uses a separate lettings process for construction and design contracts, which operates differently from standard state procurement. Construction contracts are awarded at monthly lettings using the low-bid method. Design and engineering services use qualification-based selection. INDOT also has DBE participation goals on federally funded projects.
