Rebuilding How GCs and Subs Connect

Back then, GCs and subs walked the site together. Questions got answered on the spot. Everyone left knowing they were pricing the same work
‍
Then bidding moved online. Suddenly it's 50 portals, 200 emails, and nobody's sure if they're looking at the right drawings. GCs blast the same generic invite to everyone. Subs wonder if it's even a real job. The whole thing feels like spam.

We built Downtobid to bring back what worked—just digitally.
Real relationships, clear communication, everyone on the same page. When GCs can send clean scopes from their own email and subs can track everything in one place, that trust comes back. Bids get tighter. Projects start smoother.

Frequently asked questions

How does AI package detection work?

Upload your PDF plan set. Our AI reads every sheet, identifies trade scopes, and drafts initial scope notes. You review and edit before sending—nothing goes out without approval.

How is Downtobid better than other ITB platforms?

Downtobid offers AI-powered bid package creation (15 minutes vs manual sorting), personalized ITBs from your domain (vs portal emails), and transparent per-user pricing (vs revenue percentage). Many GCs switch for the time savings alone.

How much does construction bid management software cost?

Downtobid starts at $149/month for your organization and is meant to be cost effective for GCs. For subcontractors the basic "leads" bid board starts at $119/mo and the full bid management software starts at $299/mo.

Can I import my existing sub list?

Yes. Upload via CSV and we'll match to our database, fill missing info, and flag duplicates. Your relationships stay intact.

How do I switch from my current construction bid management software to Downtobid?

We offer sub list imports from your platform (or spreadsheet) directly into Downtobid. In Downtobid, we verify contacts, update info, and flag duplicates. Most teams complete migration in under an hour.

What makes ITBs "personalized"?

Each invite includes the sub's specific scope summary, relevant sheets, and your company branding. It looks like it came from you, because it did—unlike portal emails from competitors.

Do subcontractors pay to use Downtobid?

No. Subs access planrooms and submit bids free. They can upgrade to Bid Board for advanced features like bid tracking and deadline management.
