Building Connected Alternatives: 8 Best for 2025
Written by Bridget Cooper

BuildingConnected helped solve the issue of multiple logins by giving subcontractors a single account for all GC invites. But some GCs find its massive network leads to outdated or duplicated sub listings, high licensing costs, or generic “spray-and-pray” invites. If you want a more curated approach, deeper automation, or simpler pricing, these eight solutions may be a better fit.
1. Downtobid – AI-Driven Efficiency & Quality-Focused Database
Downtobid takes a “quality over quantity” tack to bid management. Instead of blasting invites to every sub in a giant database, GCs using Downtobid invite from a smaller but actively verified sub list. Its AI engine also automates follow-ups and organizes plan sheets by trade, so you spend less time chasing unresponsive subs or manually labeling 200-page PDFs. As a result, Downtobid often yields higher coverage without spamming irrelevant contacts.
Key Features
AI Nudges & Coverage Building
Tracks which subs have (and haven’t) replied, then automatically sends gentle reminders. No more phone-tag or guesswork on coverage. Downtobid software has a lot of features which makes it the best for bid invitations.
AI-Sheeted Planroom
When you upload plans, Downtobid indexes them by trade so subcontractors see precisely what’s relevant—no account required. Sub friction is minimal, which tends to boost response rates. See why the software has the best planroom.
Verified Sub Database
Each sub contact is regularly updated, so GCs avoid emailing defunct companies or stale addresses. Data accuracy is top priority, unlike some large directories. Compare Downtobid's network vs Bluebook Construction.
Automated Follow-ups & Real-Time Tracking
A coverage board shows exactly who’s bidding, who’s declined, and which trades need more invites.
Pros
- Higher Engagement: Personalized invites + scheduled reminders lead to more timely subs.
- Time-Saving Automation: Less admin overhead, no manual scope labeling or chasing.
- Sub-Friendly: One-click plan access (no forced login) fosters better participation.
Cons
- Smaller Database: If you need ultra-niche trades in remote regions, might not be as big as older platforms yet.
- Newer Entrant: Some subs might need an introduction to Downtobid.
Why It Beats BuildingConnected
BuildingConnected’s large network can cause data bloat—leading to out-of-date or irrelevant sub profiles, plus a tendency toward “spray-and-pray” invites. Downtobid keeps things tighter, actively verifying subs and using AI to automate follow-ups. This approach spares GCs from chasing unresponsive or mis-targeted invites. If you’re looking for a modern, more curated system that still drives strong coverage, Downtobid is a compelling alternative to BuildingConnected’s massive directory model.
2. ConstructConnect (formerly iSqFt/SmartBid)
ConstructConnect unites iSqFt, BidClerk, SmartBid, and Construction Data, forming one of North America’s largest ecosystems. Unlike BuildingConnected (backed by Autodesk), ConstructConnect stands as a major, separate aggregator that GCs use to access a huge sub directory, handle plan distribution, perform prequalification, or even do digital takeoffs in one place.
Key Features
Enormous Sub Directory
Merges data from multiple legacy products, giving GCs coverage in many regions or specialized trades.
Prequalification & Takeoffs
Ties in robust prequal forms and optional digital takeoff tools, offering a more holistic precon workflow.
Coverage Reports
Real-time feedback on which subs opened invites, addenda logs, and coverage by trade.
Pros
- Massive Reach: Arguably one of the biggest sub networks if you need new trades quickly.
- All-in-One Precon: From leads to final awarding, you can do it under ConstructConnect.
- Industry Longevity: Many subs already have accounts from the old iSqFt or SmartBid days.
Cons
- Possible Data Staleness: A huge directory can contain outdated or misclassified entries.
- Pricing: Typically starts around $3,600/year for GCs, with add-ons for advanced features.
- Risk of Generic Invites: If you rely solely on “big list” blasts, you may inadvertently spam the wrong trades. This feature may not make ConstructConnect great to use.
How It Compares to BuildingConnected
Both revolve around large directories, but ConstructConnect is a separate ecosystem from Autodesk’s BuildingConnected. If you want a competitor with equally big coverage plus built-in takeoff or lead gen, ConstructConnect might be a logical pick—just be mindful of data accuracy in such a huge system.

3. Procore (Bid Module)
Procore is a household name in construction project management, expanding to preconstruction with a bid management component. GCs create ITBs, share plans, track responses, then push awarded bids directly into Procore’s scheduling, field logs, or cost modules. This “single platform” approach can be enticing if you want to unify the entire project lifecycle rather than just the bidding phase.
Key Features
All-in-One
Bids, scheduling, daily logs, cost tracking—under one login.
Project & Financial Sync
Once you choose a sub’s bid, Procore auto-generates subcontracts or purchase orders.
Integration Ecosystem
Connect with QuickBooks, scheduling tools, and more.
Pros
- Reduced Software Silos: Everything from precon to closeout is in one environment.
- Familiar Brand: Many owners or subs already use Procore.
- Strong Support & Frequent Updates: Procore invests heavily in user feedback.
Cons
- Potentially Overkill: Procore is costly and possibly too feature-heavy if you only want a simpler bidding tool.
- Learning Curve: Lots of modules can confuse smaller teams or light users.
- Bidding Not the Sole Focus: It’s strong overall, but dedicated bid features might not match specialized solutions.

Why Choose It Over BuildingConnected
BuildingConnected primarily tackles precon invites and sub networks. Procore extends far beyond that: field tracking, finances, compliance, etc. If you’re ready to unify your entire operation in one system—and budget isn’t an issue—Procore can surpass BuildingConnected’s narrower scope.
4. PlanHub
PlanHub fosters an open environment where GCs post projects (often at no cost) and subs see all their invites in one dashboard. It’s user-friendly and aims for sub convenience, paralleling BuildingConnected’s single-login concept but with simpler features and a more cost-friendly model.
Key Features
GC Free Posting
Budget-conscious GCs can start at zero cost, with advanced features on paid tiers.
Unified Sub “Bid Board”
Similar to BuildingConnected, a single sub login for all invites in PlanHub, so they aren’t forced into separate accounts.
In-App Viewer & Basic Takeoff
Premium plans give subs or GCs integrated plan viewing and some quantity takeoff functionality.
Pros
- Straightforward & Sub-Friendly: Minimal friction or forced signups.
- Low Barrier: Start free, only upgrade if you need more tools.
- Modern UX: Often praised for being easy on both GCs and subs.
Cons
- Smaller User Base: Still expanding coverage in certain niches or regions.
- Premium Upsells: In-depth features (like robust takeoff) sit behind paywalls. The PlanHub costs add up.
- Limited GC Customization: Less advanced analytics or brand-ability than bigger solutions.

Why It Beats BuildingConnected
BuildingConnected can be pricier and rely on a giant directory. PlanHub is comparatively minimal, free to start, and fosters a similar “one sub login” approach. If BuildingConnected’s cost or complexity turns you off, PlanHub’s simpler, more budget-friendly design could be your go-to.
5. Pantera Tools
Pantera Tools merges a basic ITB management system with optional project management. One standout feature is white-label branding—your planroom can display your company branding, so subs feel they’re in your portal rather than a big, external network. Pantera’s approach is cost-conscious, focusing on easy invites, real-time sub tracking, and a user-friendly planroom.
Key Features
Branded Invitations
GCs can match invites and planroom to their corporate identity for a professional, personalized experience.
Online Planroom
Store and share all project docs, track who viewed or downloaded them in real time.
Optional PM Modules
Daily logs, RFI, scheduling—basic features included for GCs that don’t want a separate system.
Pros
- Affordable: Typically cheaper than large enterprise tools.
- Easy to Deploy: Minimal training required, good support.
- Sub Convenience: No forced logins or complicated steps, leading to decent sub coverage.
Cons
- Fewer Advanced Analytics: Lacks the robust data or AI tools of some alternatives.
- Network: Not as huge as BuildingConnected’s 1M+ directory (though it can tie into Blue Book).
- Occasional UI Quirks: Some friction managing multiple active bids simultaneously.
Why Choose Over BuildingConnected
If you dislike the “one massive public network” approach or BuildingConnected’s cost, Pantera is a simpler, more private alternative. You control branding and keep things user-friendly, without paying extra for advanced coverage you may not need.
6. PipelineSuite
PipelineSuite keeps bidding straightforward: you manage your sub list, send invites, track responses, and host project documents in a basic planroom. There’s no huge public directory or fancy AI—just a private environment for GCs who prefer controlling their own data. This suits smaller teams that don’t want the complexity or cost of a big platform.
Key Features
Your Own Sub Database
No forced network. You add, edit, or remove subs at will.
Mass Email/Fax Invites
Quickly send out ITBs, see who opens them, log yes/no replies.
Docs & Addenda
Store plans, specs, and issue addenda notifications. PipelineSuite tracks downloads.
Pros
- Budget-Friendly: Generally cheaper than high-end solutions like BuildingConnected.
- Minimal Training: The interface is straightforward.
- Data Control: You’re not reliant on a shared directory or sub-maintained profile.
Cons
- No AI or Big Directory: If you need new trades outside your usual list, you must source them elsewhere.
- Limited Integrations: Doesn’t tie deeply into PM or accounting systems.
- UI Less Polished: Feels basic compared to modern SaaS tools.
Why Pick It Over BuildingConnected
BuildingConnected might be overkill if your sub relationships are stable and local. PipelineSuite is simpler, cheaper, and you fully own the contact data. If you prefer a private approach without a giant subscription, PipelineSuite is a solid minimal alternative.
7. SmartBid
SmartBid, formerly a standalone product from ConstructConnect, is still used by some GCs despite ConstructConnect encouraging them to upgrade to the main platform. It’s a private database approach, letting you maintain sub contacts and send invites. Some GCs like its simpler environment versus BuildingConnected’s public network, but be mindful that it’s not being heavily updated.
Key Features
Private Sub Database
You manage who sees which project; no forced directory or cross-sharing.
Addenda & Basic Tracking
Email-based invites and plan distribution, plus a coverage dashboard to see who’s responded.
Integration with ConstructConnect
If you do want external leads or advanced takeoff, you can bolt on other modules from the ConstructConnect suite.
Pros
- Familiarity: Many GCs used it for years, so the learning curve can be low.
- Controlled Data: You decide exactly which subs get invites; it’s not a big network.
- ConstructConnect Ties: Some synergy if you also use iSqFt or the CC leads product.
Cons
- Limited AI or Modern Features: Doesn’t address sub-lon login or data staleness on its own.
- Phasing Out: ConstructConnect is pushing users toward their “unified” platform.
- Potential Data Aging: If you don’t keep sub data fresh, it quickly goes stale. Outdated contacts may not warrant paying the price of SmartBid.
Why It’s an Alternative to BuildingConnected
Some GCs prefer SmartBid’s private environment over BuildingConnected’s open network. If your sub base is local, stable, and you don’t need the big public directory, SmartBid remains a direct competitor. Just note that its future updates might be limited as ConstructConnect invests in its main product.
8. BidMail
BidMail is an older, simpler bid management tool known for low-friction workflow. It doesn’t push advanced analytics or a huge sub directory, but GCs can create and distribute ITBs, track views, and store plan sets. Some consider it “old reliable,” though critics say it hasn’t seen major updates in years, leading to slowdowns.
Key Features
Straightforward ITB Sending
Upload plans, select subs, and track who viewed or downloaded.
Planroom & Time Tracking
An optional time/attendance feature is included, albeit rarely used by large commercial GCs.
Simple “Sent Log”
Basic coverage logs show sub activity. Minimal frills or custom forms.
Pros
- Low-Fuss Approach: Some GCs appreciate that it just does invites without add-on complexities.
- Often Cheaper: Pricing can be around $3,500–$4,000/year, beating many enterprise tools.
- Familiar: Has been around for over a decade, so some older subs know the system well.
Cons
- Slow Dev Pace: Reportedly few updates since ~2014, leading to dated UI or occasional slowness.
- No Large Directory: Must rely on your own sub contacts. No AI or big public network.
- Limited Features: Lacks advanced analytics, prequalification, or synergy with other software.

Why It May Outdo BuildingConnected
If you’re simply looking for a basic, cost-effective ITB solution and want to avoid BuildingConnected’s bigger price tag or multi-sub synergy approach, BidMail is simpler and still functional. However, if you need robust data analytics or AI-driven coverage, you’ll find BidMail lacking.
Conclusion
While BuildingConnected transformed sub login simplicity, many GCs find its massive public directory can create spam invites or data inaccuracy. Others balk at licensing costs or long learning curves. These eight alternatives address different pain points:
- Downtobid: AI-based coverage, curated data, sub-friendly planroom.
- ConstructConnect: Another huge aggregator (ex-iSqFt/SmartBid) with big coverage & prequal.
- Procore: Integrates bidding into an all-in-one PM suite, from precon to closeout.
- PlanHub: Free or low-cost approach, sub-friendly “bid board.”
- Pantera Tools: White-label branding, quick invites, cost-effective.
- PipelineSuite: Private sub data, simpler interface, budget-friendly.
- SmartBid: Private environment from the same corporate family as iSqFt, though updates are slowing.
- BidMail: Minimalistic tool known for a “just works” approach but few modern touches.
Each platform solves a different piece of the puzzle—some focus on AI automation (Downtobid), others on massive coverage (ConstructConnect) or lightweight affordability (PipelineSuite, BidMail). By clarifying your specific frustrations with BuildingConnected—be it stale data, high costs, or one-size-fits-all invites—you can pick a solution that aligns better with your preconstruction workflow. Good luck elevating your bid management in 2025!
