About
Downtobid is a purpose-built AI bidding platform that modernizes how general contractors and subcontractors collaborate during the preconstruction phase. For GCs, the workflow starts with uploading a PDF plan set — the AI reads every sheet, identifies trade packages, drafts scope notes, and prepares personalized Invitations to Bid (ITBs) ready to send from the GC's own email domain. This replaces hours of manual sorting with a process that takes as little as 15 minutes. GCs can then monitor real-time coverage: who opened the invite, who's actively bidding, and who needs a follow-up nudge. For subcontractors, Downtobid provides a unified bid board that consolidates every invite, deadline, and RFI across all active projects into a single calendar-style view. Subs can discover new commercial GC relationships, prevent double-bidding by assigning estimators and tracking progress across the team, and reply to invites faster than the competition. Downtobid positions itself as a direct alternative to BuildingConnected, SmartBid, PlanHub, ConstructConnect, and Procore for bid management. Pricing starts at $149/month per organization with transparent per-user billing rather than revenue-percentage fees. Case studies show customers like GH Pastor cutting time-to-packages from over 2 hours to 15 minutes and nearly doubling average bids per package.
Key Features
- AI Trade Package Detection: Automatically reads every sheet in an uploaded PDF plan set, identifies trade scopes, and drafts initial scope notes — reducing hours of manual sorting to about 15 minutes.
- Personalized ITB Creation & Sending: Generates scope-specific Invitations to Bid for each subcontractor and sends them from the GC's own email domain, increasing open rates and trust compared to generic portal blasts.
- Real-Time Bid Coverage Dashboard: Tracks which subs have opened invites, confirmed bidding intent, or gone silent — so GCs can follow up strategically and maintain full trade coverage.
- Subcontractor Bid Board: Gives subs a single consolidated view of all active invites, upcoming deadlines, and open RFIs across every project, replacing scattered emails and portals.
- Team Coordination & Double-Bid Prevention: Allows estimating teams to assign team members to specific bids and track progress, eliminating duplicate efforts and missed opportunities.
Use Cases
- A general contractor uploads a commercial office building plan set and uses AI to generate trade packages and personalized ITBs for 40+ subcontractors in under 20 minutes.
- An estimating manager monitors real-time bid coverage on a data center project, identifying which trades are underrepresented and nudging specific subs to confirm participation.
- A subcontractor uses the Bid Board to consolidate invites from 12 different GCs into one deadline calendar, ensuring no bid due date is missed.
- A preconstruction team eliminates double-bidding by assigning each estimator to specific packages and tracking progress centrally across 24 concurrent active projects.
- A mid-size GC switches from BuildingConnected to Downtobid to send invites from their own email domain and improve sub response rates on hard-bid public projects.
Pros
- Dramatic Time Savings: AI package detection reduces bid package creation from 2+ hours to as little as 15 minutes, freeing estimators for higher-value work.
- Higher Sub Response Rates: Invites sent from the GC's own email domain feel personal and legitimate, resulting in significantly better engagement than generic portal notifications.
- Unified Platform for Both GCs and Subs: Serves both sides of the bidding relationship, making it a single tool that can replace multiple disconnected portals and inbox management workflows.
- Transparent, Predictable Pricing: Flat per-user monthly pricing starting at $149/month avoids the revenue-percentage fees charged by some competing platforms.
Cons
- Construction-Only Use Case: The platform is purpose-built for commercial construction bidding and offers no value outside that specific industry vertical.
- Paid-Only Tier: There is no free plan; the starting price of $149/month may be a barrier for very small contractors or independent subs just evaluating the tool.
- AI Accuracy Requires Human Review: AI-generated scope notes must be reviewed and approved before sending, meaning teams still need an estimator in the loop — the tool accelerates work but does not fully automate it.
Frequently Asked Questions
How does AI package detection work?
You upload your PDF plan set to Downtobid. The AI reads every sheet, identifies trade scopes (e.g., concrete, framing, electrical), and automatically drafts initial scope notes for each package. You review and edit everything before any invite goes out — nothing is sent without your approval.
How is Downtobid different from BuildingConnected or SmartBid?
Downtobid offers AI-powered bid package creation (15 minutes vs. manual sorting), personalized ITBs sent from your own email domain instead of portal emails, and transparent per-user pricing instead of revenue-based fees. Many GCs switch primarily for the time savings and higher sub response rates.
How much does Downtobid cost?
Downtobid starts at $149/month per organization. Pricing is per-user and billed transparently — unlike some competitors that charge a percentage of project revenue.
Can subcontractors use Downtobid for free?
Subcontractors can use the Downtobid Bid Board to track invites, deadlines, and RFIs. Check the current pricing page for the latest sub-tier details, as GC and sub plans may differ.
What file formats does Downtobid support for plan uploads?
Downtobid supports PDF plan sets for AI analysis. The AI processes the uploaded drawings to identify trade packages and draft scope notes automatically.
