Your Bid Invitations Still Live in Excel. Your Competitors Moved On.
If you're a GC issuing 40+ invitations per project, you've felt the seat-license math break -- $18k/year for software that slows down your subs.
Construction bidding software is a different vertical from auction software -- it is not auctions, it is bid management. General contractors invite sub-trades to bid on project line items. Sub-trades respond with bids including labour, material, and alternates. GCs compare, select, and award. Procore, BuildingConnected, and ConstructConnect dominate but charge per-seat fees that compound fast and lock in both GCs and sub-trades. Social Animal builds custom bidding software for GC-led bid invitations, sub-trade CRMs, multi-trade marketplaces, and specialty verticals (electrical, mechanical, demolition). Invitation-to-bid flows, structured bid comparison, plan room integration, prequalification workflows, and award automation.
Your general contractor breaks a commercial project into scopes -- concrete, framing, electrical, mechanical -- then invites prequalified sub-trades to respond with structured bids. Those bids arrive with labour breakdowns, material costs, equipment rentals, alternates, allowances, and exclusions spelled out line by line. Your PM compares them side-by-side, identifies scope gaps between subs, normalises totals, and awards the work. That's the core loop. Beyond bid management, your platform handles prequalification verification -- insurance expiration, bonding capacity, safety records, financial review -- plus plan room access for drawings and addenda, invitation distribution, and award automation. Procore and BuildingConnected own the commercial market. Their per-seat fees compound fast: a 20-PM operation pays $40–80K annually just for bid invitations. Custom platforms pay for themselves in 12–18 months for GCs above $50M in annual construction volume. Social Animal builds these bid-management platforms for general contractors, sub-trades, and multi-trade construction marketplaces.
What is holding your current website back?
Common gaps we find in nearly every audit.
How We Build This Right
Every safeguard, built in from Day 1.
Invitation-to-Bid Distribution
The invitation engine handles scope-specific outreach to your prequalified sub pool. Automatic follow-up reminders go out without anyone chasing them manually. RSVP tracking shows you who's seen the invitation and who hasn't responded. And deadline enforcement is hard-coded -- no more "we forgot to follow up with three subs before close."
Structured Bid Response Forms
Every bid comes in on a structured line-item template that breaks out labour, material, and equipment separately, plus alternates, allowances, and exclusions called out explicitly. No more PDF bids that can't be compared side-by-side. The days of re-keying numbers from emailed PDFs into a spreadsheet at 11pm are done.
Scope-Gap and Bid Comparison
Multi-sub comparison runs on structured data, not reformatted PDFs. The scope-gap analysis is the part estimators actually get excited about -- it surfaces what Sub A included that Sub B excluded, right in the comparison view. Normalised totals per scope so you're comparing apples to apples, not the lowest number someone typed on a form.
Prequalification Workflow
Insurance certificates tracked with expiration alerts built in. Bonding capacity verified. Safety records documented and current. Financial review on file. And here's the enforcement piece that matters most: only prequalified subs actually see invitations for specific scopes. Unqualified bids don't enter the pipeline because they literally can't get in.
Plan Room Integration
BlueBeam Revu, PlanGrid, and Fieldwire all integrate directly. Drawings, specs, and addenda are accessible from inside the bid response flow -- not in a separate tab, not in a separate login. Subs see the current set while they're filling out their bid. Addenda updates push automatically.
Award Automation and Contract Generation
Once a bid's selected, the platform triggers contract generation from your template library. E-signature flow goes out immediately. Insurance requirements get verified against what's on file. Kickoff notifications fire to the right people. The gap between "awarded" and "under contract" shrinks from days to hours.
What We Build
Purpose-built features for your industry.
Build GC-side and sub-side platforms in one system -- invitations, comparison tools, and award workflow for your PMs; structured response forms and award history for your subs
Stop paying BuildingConnected $40–80K per year for a 20-PM operation -- your custom platform pays for itself in 12–18 months and eliminates recurring per-seat fees entirely
Deploy marketplace mode to connect multiple GCs with a shared pool of prequalified subs -- more bid invitations for subs, more competitive responses for your GCs
Eliminate bid comparison done in Excel where every PM builds their own spreadsheet -- scope gaps get missed, awards go to whoever looked cheapest, change orders follow and margin erodes
Configure specialty trade verticals with line-item structures specific to electrical, mechanical, roofing, demolition -- not generic templates your estimators hack into shape
Automate prequalification tracking with expiration alerts -- subs' insurance lapses, bonding capacity shifts, safety records go stale, and unqualified subs slip into your bid pipeline
Track bid analytics and win rate by GC, scope type, bid size range -- operational data sitting in disconnected spreadsheets pulled into one queryable place
Integrate plan room with bid platform in one pane -- subs toggling between BlueBeam and BuildingConnected lose context on addenda, miss updates, and respond to the wrong drawing set
Enable mobile bid response from job sites -- photo upload for existing conditions, voice-to-text notes, structured forms that work on a phone without pinch-and-zoom disasters
Replace gut-feel sub selection with queryable bid history -- win rate, on-time completion, change-order rate by sub become data instead of "we've always used Rodriguez Electric"
Feed every bid into a historical cost database -- future projects benchmark against real past data from your pipeline, not national averages from a two-year-old report
Compound estimating accuracy over time as your historical cost database grows -- pricing intelligence that gets sharper with every bid that runs through your platform
Built on a Modern, Secure Stack
Our Development Process
From discovery to launch. Quality at every step.
GC or Sub Operations Audit
Week 1-2We start by reviewing your current bid workflow end-to-end -- current tooling like Procore, BuildingConnected, or Excel, how prequalification is handled today, and what specialty trades have unique requirements. No assumptions. We map what you're actually doing before we design anything.
Bid Data Model and Workflow Design
Week 2-4From the discovery, we define scope structure, the bid line-item schema for each trade, the prequalification model, plan room integration plan, and the contract template library. This is where most of the real decisions get made -- and getting it right here saves a lot of rework later.
Build: Invitation, Response, Comparison, Award
Week 4-14Full platform build covering both GC and sub roles: structured bid flow, prequalification engine, plan room integration, and award automation. Built to your workflow, not the other way around.
Pilot Project and Team Training
Week 14-16Live pilot on one or two real projects -- not a sandbox, actual bids with actual subs. We train estimating staff and PMs together. Comparison UX gets tuned based on what real bid data exposes, because there's always something you don't see until the data's live.
Full Rollout and Ongoing Development
Week 16+Once the pilot's solid, we roll out to the full project pipeline. Retainer covers ongoing feature development, sub onboarding support, and integration expansion as your toolset evolves.
