These platforms are the key to not just competing for available construction jobs but also winning contracts and growing one’s business.

So, what are the top subcontractor bidding websites? This article highlights the seven sites where you can find construction bid opportunities, including Dodge Construction Central and PlanHub.

We’ll highlight their key features and pricing options to help you find the best construction bidding website that aligns with your business needs.

1 - Downtobid: The Must-Have Bidding Tool for GCs and Subcontractors

We're starting off with the best, as Downtobid deserves special attention due to its unique features and capabilities. This is the only site on our list that uses artificial intelligence (AI) to connect GCs with subcontractors for bidding purposes. 

In essence, it is a useful site for both GCs and subcontractors as it handles bidding from the identification of bid packages to sending personalized ITBs. There is no better way to save time than with Downtobid. 

Key Features

Downtobid’s AI simplifies the bidding process by turning construction plans into bid packages within minutes. This allows GCs to quickly draft and send invite emails to a network of local, qualified subcontractors, ensuring that projects have the best possible bid coverage. 

For subcontractors, this means they get bid invitations that are well within their qualifications, increasing the likelihood of winning the project. 

Another feature is the comprehensive subcontractor database. Downtobid ensures that GCs can find the right subcontractors for their projects.

Whether the subcontractor specializes in electrical, plumbing, HVAC, drywall, concrete, or masonry, Downtobid will match you with relevant construction bids in your field. 

Downtobid automatically follows up with subcontractors to ensure prompt responses and increase bid participation, freeing up general contractors to focus on other critical tasks.

Downtobid’s Project Bid Board is a notable feature for subcontractors. It offers them bid-tracking software that automates the sorting and tracking of bid-related emails.

This centralized dashboard improves productivity since subcontractors can manage their bids and communication all in one place.

“I was getting forwarded the same email 5-6 times a day. That happened every time there was an update or a bid date change or an addendum. This Bid Board takes all 5 of those emails, organizes it as the same exact email, and puts it in a nice place for you.”—Jake Whittle, Owner of Niehaus

Subcontractors can enjoy tailored access to online plan rooms to review project documents and propose bids.
