Reverse auctions have gained attention in construction procurement, though they remain controversial. Understanding how they work—and when they make sense—helps contractors decide whether to participate and how to approach them strategically.
What Is a Reverse Auction
Basic Concept
In a reverse auction, sellers (contractors) compete by lowering their prices in real-time. Unlike traditional sealed bidding, participants see competing bids and can reduce their price to remain competitive.
Traditional Bidding
Submit sealed bid → Wait → Results announced
Reverse Auction
Submit initial price → See other prices → Lower price to compete → Repeat until auction closes
How It Works
- Owner defines scope and requirements
- Qualified contractors are invited to participate
- Auction opens with contractor initial prices
- Contractors lower prices in real-time
- Auction closes after defined period/rules
- Lowest price (typically) wins

Conclusion
Reverse auctions are a tool that can be appropriate for certain procurement situations—primarily commodity purchases with clear scope. For complex construction work, they often create more problems than they solve.
As a contractor, approach reverse auctions with clear-eyed analysis. Know your numbers, set firm limits, and be willing to walk away from unsustainable pricing. Winning work you can't profitably execute isn't success—it's a path to business failure.
If you participate, do so strategically and disciplined. If the process doesn't fit your work or values, it's appropriate to decline participation and focus on procurement approaches that align with your business model.
