What is bid board software, anyway?
Bid board software helps subcontractors and material vendors organize, track, and manage construction bid invitations in a centralized spot. Instead of digging through emails or maintaining manual spreadsheets to track project opportunities and deadlines, they automatically capture bid invites and organize them into a dashboard where teams can review, assign, and respond to opportunities.
The best bid software eliminates the admin headaches that come with traditional bid tracking. No more forwarding emails to team members, copying project details into spreadsheets, or wondering if someone else already responded to an invitation.
Bid board software should work for you, not against you. The right tool captures every opportunity automatically while keeping your team organized and focused on winning work.

The integrated takeoff tools can be helpful if you're doing your own quantity calculations. But most subcontractors already have preferred estimating software, so this integration might not add much value.
