Construction Takeoff Software: A Subcontractor’s Guide to the Tools in 2026
A non-ranked guide to the construction takeoff tools subcontractors actually use in 2026 — from legacy digital takeoff to the new wave of AI-native, trade-specific platforms. Updated quarterly.
Construction takeoff software for subcontractors has changed quickly. For years, the category mostly meant digital takeoff software: upload plans, calibrate scale, measure areas and lengths, count items, export quantities, then price the job somewhere else.
That baseline still matters. Plenty of subcontractors still need reliable on-screen measurement, assemblies, markups, and quantity exports. But in 2026, the category is splitting. Legacy construction takeoff tools that many estimators already know are adding AI features to speed up counting and measurement. At the same time, AI-native platforms are being built around computer vision from the ground up, often for one trade at a time.
This guide is a non-ranked reference. The tools below are grouped by approach for readability, not ranked within or across groups. A tool listed first is not being presented as stronger than a tool listed later.
A quick terminology note: takeoff answers “how much is there?” Estimating answers “what does it cost?” Some tools stop at quantity takeoff. Others carry those quantities into estimating, assemblies, bid packages, or proposal workflows. That distinction matters because the handoff after takeoff is often where subcontractors still lose time.
For each tool, the Approach field is factual: AI-forward, AI-assisted, or manual-forward. It describes how the tool performs takeoff. It is not a quality judgment.
Market Context: How AI Takeoff Software Is Changing Digital Takeoff in 2026
AI takeoff software is moving fast because takeoff is one of the clearest places where computer vision can reduce repetitive estimating work. A plan set has visual information. The estimator needs counts, measurements, areas, assemblies, and quantities. That makes takeoff a natural target for automated takeoff tools.
Two forces are shaping the market.
First, established providers are adding AI to mature digital takeoff products. STACK named Viyas Sundaram CEO in March 2026 to lead its next chapter of AI innovation. ConstructConnect has added Takeoff Boost to On-Screen Takeoff, using AI-assisted automation on top of a long-standing manual takeoff core. Trimble’s PlanSwift, AutoBid, and Accubid remain important legacy tools, especially in MEP, while AI features are still emerging around those workflows.
Second, AI-native companies are entering with narrower wedges. Bobyard raised a $35 million Series A in December 2025. Rebar raised a $14 million Series A in March 2026. YC-backed companies such as Bild AI, Fresco, and Rudus are building around specific trades such as Division 8 and concrete.
For a subcontractor, this means more choice, faster change, and more vendor claims to test carefully. For deeper analysis on why AI estimating is moving trade by trade, read AI Estimating Is Being Won One Trade at a Time.

AI-Forward, Multi-Trade Construction Takeoff Software
An AI-native takeoff and estimating platform built for commercial trade contractors. Proprietary, trade-specific computer-vision models detect and quantify items directly from plans — Bobyard says this automates a large share of the takeoff and reports an average 65% reduction in takeoff time (company-reported figures). Bobyard 2.0 adds an AI workbench, a human review workflow, and materials and pricing, so the tool carries past takeoff into estimating. Started in landscaping and has expanded into electrical, sitework, and the finishing trades.
What it doesn't do
Trade coverage is still expanding — plumbing and mechanical/HVAC are on the roadmap, so fit outside the live trades may be limited until those ship. Pricing is not published. As with any AI-native takeoff tool, accuracy depends on plan quality, and the time-savings figures are Bobyard's own claims rather than independent benchmarks. Third-party reviews are still thin given how new the platform is.
Integrates with
Exports takeoff quantities and estimates for downstream use. As a newer AI-native platform, its integration ecosystem is less extensive than the legacy incumbents; confirm current integrations with the vendor for your specific stack.
Who it's for
Commercial trade contractors in Bobyard's supported trades — landscaping, sitework, electrical, and finishes (flooring, drywall, paint, insulation, doors/windows) — who want an AI-forward tool built for subcontractors rather than a legacy generalist. Teams comfortable adopting a newer, well-funded platform.
Founded 2023, based in San Francisco. Raised a $35M Series A in December 2025 led by 8VC, with Pear VC, Primary, Tishman Speyer, RXR, Caffeinated Capital, and Merrick Ventures participating — the best-funded AI-native player targeting commercial subs directly.
AI takeoff for architectural plans that auto-detects, measures, and labels rooms and spaces, with a claimed ~98% accuracy (Togal's figure). Includes drawing-set comparison to spot changes between plan revisions, and Togal.CHAT to query a plan set in natural language. One of the best-known AI takeoff brands among subs, built by estimators for estimators.
What it doesn't do
Pure takeoff — no pricing or estimating engine; it integrates out to estimating tools instead. Strongest on architectural and space-based takeoff (hotels, multifamily, repetitive floor plans); reviewers note it is weaker on dense MEP and structural/concrete work, where volume and reinforcement calculations aren't supported. Accuracy drops on low-resolution or scanned plans, and the ~98% figure is a vendor claim.
Integrates with
Integrates out to estimating and downstream tools including OnScreen (OST), eTakeoff, Ediphi, Procore, and Bluebeam. Supports all common drawing formats (PDF, JPEG, PNG, TIFF).
Who it's for
GCs and commercial subs — especially painting, flooring, drywall, and finishes estimators — who want fast space and area takeoff and are comfortable pairing it with a separate estimating tool.
Features
✓ AI Auto-Detect✓ Drawing Compare✓ AI Plan ChatNo Estimating EngineArchitectural-Leaning
Ownership & funding
Founded 2020 in Miami, FL by Patrick Murphy, of the Coastal Construction family. Roughly $5M raised per third-party trackers, with OEM/partner distribution via eTakeoff. Privately held.
A largely done-for-you takeoff service: the sub uploads plans and specs, Beam's AI extracts quantities, a human QA team reviews, and finished takeoffs are delivered in 24–72 hours as Excel or PDF. Reads specs, notes, and assemblies. Also offers instant self-serve HVAC and plumbing takeoff plus BIM CoPilot services, and is expanding into bid management.
What it doesn't do
The core model competes with hiring an estimator more than with buying software — in the delivered-service model, the sub doesn't drive the takeoff themselves. The 24–72 hour turnaround is a dependency for tight bid deadlines. Pricing is quote-based and hybrid (software plus service), so it is not transparent up front.
Integrates with
Delivers output in Excel and PDF for use in any downstream estimating tool. Offers API and BIM CoPilot services; confirm current integrations with the vendor.
Who it's for
Capacity-constrained subs and GCs across HVAC/mechanical, plumbing, concrete, electrical, steel, civil, and landscaping who would rather outsource takeoff than run it in-house — useful for firms without a dedicated estimator.
Features
✓ AI + Human QA✓ Multi-Trade✓ Done-For-You24–72 hr TurnaroundNo Public Pricing
Ownership & funding
A product of Attentive.ai, founded 2017 with operations in Bengaluru, India and the US. VC-backed; public trackers list Peak XV/Sequoia-India-linked funds and Vertex among investors. Expanding from takeoff into bid management.
Cloud AI takeoff and estimating with Auto Measure, Auto Count, AI Suggest, and the 'Caddie' AI agent that can run measurements and build bills of quantities from prompts. Includes an Excel-like estimating layer, assemblies, and reporting, so it carries from takeoff through estimating. Users report roughly 40% time savings on manual takeoff (company/user-reported figures).
What it doesn't do
As a smaller, bootstrapped vendor, its long-term independence is uncertain given reported M&A interest in 2025. Works best on vector drawings and modern floor plans; reviewers note auto-measure can be messy on scanned or poor-quality plans and require cleanup. Trade depth is generalist rather than specialized, so MEP-heavy subs may find less trade-specific intelligence than a dedicated tool.
Integrates with
Excel import/export for takeoff templates and bills of quantities. Works from PDF plans and CAD drawings. Confirm current integrations with the vendor for your stack.
Who it's for
SMB subs, estimators, and quantity surveyors — strong with flooring, painting, finishes, and QS work — who want the lowest-cost entry into AI takeoff and are comfortable with a smaller vendor.
Founded 2017 in London, UK. Essentially bootstrapped, with roughly $2.4M ARR per GetLatka (2025). An M&A offer was reported in April 2025, making it a possible consolidation target.
A vertical AI 'operating system' for commercial HVAC in which computer vision reads blueprints and spec books and auto-builds bills of materials and quotes — Rebar claims 60–70% faster (company-reported figure) — with agentic automation that extends beyond takeoff into downstream workflow. Electrical and plumbing are on the roadmap.
What it doesn't do
Built supplier/distributor-first rather than for subcontractors, so a sub is not the primary user today. Currently HVAC-centric; electrical and plumbing are roadmap, not shipped. Enterprise and quote-based with no public pricing. The 60–70% speed figure is a vendor claim.
Integrates with
Agentic workflow automation connects takeoff output into quoting and downstream steps. As an enterprise platform, integrations are handled per deployment; confirm with the vendor.
Who it's for
Commercial HVAC suppliers, distributors, and contractors. Relevant to mechanical subs watching where supplier-side automation is heading, and to firms whose distributors adopt it.
Features

Ownership & funding
Founded 2024 in New York, NY. Raised a $14M Series A in March 2026 led by Prudence, with Zero Infinity Partners, Founder Collective, Villain Capital, and Optimist Ventures. Reports roughly 40 clients, seven of whom are investors.
AI estimating for Division 8 (doors, frames, and hardware) that reads blueprints and specs, auto-generates opening and door schedules, prices the bid, and exports to Division 8 ERPs (Comsense, Avaware, ProTech). Bild says clients bid ~50% more with smaller estimating teams (company-reported figure). A clean example of the deep single-division playbook.
What it doesn't do
Purpose-built for Division 8 — not applicable to other trades. Subscription and quote-based with no public pricing. Early-stage with a thin public review history. The '50% more bids' figure is a vendor claim.
Integrates with
Exports to Division 8 ERP and estimating systems: Comsense, Avaware, and ProTech. Confirm current integration list with the vendor.
Who it's for
Division 8 distributors and subcontractors specifically — doors, frames, and hardware.
Features
✓ AI-Native✓ Reads Plans + Specs✓ Div 8 ERP ExportDivision 8 OnlyNo Public Pricing
Ownership & funding
Founded 2024 in San Francisco. Y Combinator W25; raised a $3.1M seed led by Khosla Ventures in July 2025 (~$3.5M total). Pivoted from broad blueprint AI to the Division 8 wedge.
AI takeoff and estimating for Division 8 that automates spec reading, hardware-set cross-referencing, and schedule building. Fresco claims 99% accuracy and a ~70% time reduction, and says it has processed 3,000+ takeoffs for GCs and Division 8 subs (company-reported figures). Describes Division 8 as its beachhead and is expanding across spec-heavy trades.
What it doesn't do
Focused on Division 8 — limited relevance to other trades today. Quote-based with no public pricing. Early-stage with a thin public track record. Accuracy and time-savings figures are Fresco's own claims. A direct Bild AI competitor — two funded startups on one division.
Integrates with
Exports takeoffs and schedules for Division 8 estimating workflows. Confirm current integrations with the vendor.
Who it's for
Division 8 subs and GCs — doors, frames, and hardware — and spec-heavy trades as Fresco expands.
Features
✓ AI-Native✓ Spec Reading✓ Hardware SetsDivision 8 FocusNo Public Pricing
Ownership & funding
Founded around 2024 in San Francisco. Y Combinator-backed, early stage (seed). Note: some funding trackers report larger totals for a similarly named company — verify carefully before citing any figure.
AI takeoff and estimation for concrete that auto-identifies footings, walls, columns, and slabs from plans. Rudus claims a ~70% reduction in estimation time and says it helps concrete contractors bid 3x more projects per year (company-reported figures). Another clean single-trade wedge, mirroring the Division 8 pattern in concrete.
What it doesn't do
Concrete-only — not applicable to other trades. Quote-based with no public pricing. Early-stage with a thin public track record. The time-savings and bid-volume figures are vendor claims.
Integrates with
Exports concrete quantities and estimates for downstream use. Confirm current integrations with the vendor.
Who it's for
Concrete subcontractors specifically.
Features
✓ AI-Native✓ Concrete-Specific CV✓ EstimatingConcrete OnlyNo Public Pricing
Ownership & funding
Founded around 2024 in San Francisco. Y Combinator-backed, early stage (seed). Part of the pattern of YC seeding one AI takeoff startup per major trade.
Self-serve AI takeoff with deep MEP and electrical intelligence — assembly expansion, conduit and wire inference, and built-in pricing. Notably processes DWG/DXF CAD files in addition to PDFs, which is rare in the category and valuable for electrical subs working directly from CAD.
What it doesn't do
MEP and electrical focus means limited fit outside those trades. Pricing is not broadly published. Early-stage with a limited public track record and few reviews. CAD-file support and MEP depth are the differentiators to verify against the current product.
Integrates with
Processes both PDF and DWG/DXF CAD files as input — a differentiator in the category. Built-in pricing logic; confirm downstream integrations with the vendor.
Who it's for
Electrical and mechanical subs, especially those who work from CAD files and want assembly-level intelligence and conduit/wire inference.
AI takeoff through to transaction: AI counts items with per-item confidence scores and an audit trail, then carries into estimating, client proposals, and a procurement layer for factory-direct material sourcing. The confidence-score-plus-audit-trail approach is a distinctive take on trust and verification in AI takeoff.
What it doesn't do
Broad scope (takeoff through procurement) from an early-stage vendor means depth may vary by trade; verify per-trade maturity before committing. Newer entrant with a limited public track record. Confidence-scoring and sourcing claims should be checked against the current product.
Integrates with
Includes a built-in procurement layer for factory-direct sourcing, plus estimating and proposal generation in one workspace. Confirm external integrations with the vendor.
Who it's for
SMB subs and GCs in its flagship trades — electrical, concrete, flooring, and drywall — who want takeoff with built-in confidence scoring and an optional procurement path.
Features
✓ AI Confidence Scoring✓ Estimating + Proposals✓ Procurement LayerEarly-Stage Depth✓ Public Pricing
Ownership & funding
US-based, early stage. VC status not broadly disclosed. Positions aggressively against Togal and STACK in its content marketing.
A widely used cloud takeoff and estimating platform that has added AI: auto-count, AI quantity detection, and a GPT-style assistant, on top of prebuilt material and assembly catalogs, a plan room, and bid tracking. Integrates broadly with the tools subs already run. The incumbent many subs already know, now investing in an AI chapter under a new CEO.
What it doesn't do
AI features are an assist on a manual core rather than an AI-native engine, and are gated to the Premium tier. Not trade-specialized the way the single-trade AI tools are. Reviewers cite steady annual price increases and the lack of a mobile app for the takeoff/estimate product. Depth of the newest AI features is still maturing.
Integrates with
Procore, Autodesk, Sage, Acumatica, and QuickBooks, plus prebuilt material and assembly catalogs. Partnerships with Winsupply and Pine Services Group.
Who it's for
Specialty subs (its core), plus GCs and suppliers, who want an established multi-trade takeoff-and-estimating platform with broad integrations and a long track record.
Features
✓ AI Auto-Count✓ Estimating✓ Broad IntegrationsAI on Premium TierNo Mobile App
Ownership & funding
Founded 2010 in Cincinnati, OH. PE-backed (Level Equity and others), with roughly $29–30M raised over six rounds and an estimated ~$31.8M revenue (2024). New CEO Viyas Sundaram joined in March 2026 to lead an 'AI innovation' chapter.
The long-standing commercial takeoff leader (On-Screen Takeoff), now with Takeoff Boost adding AI-assisted auto-takeoff, bundled with ConstructConnect's project-leads and bid-management network. The closest legacy analog to a leads-plus-takeoff bundle, and a tool a large installed base already runs on. PlanSwift also sits in this legacy digital-takeoff tier.
What it doesn't do
A manual-takeoff core with AI assistance layered on rather than an AI-native engine — the installed base most exposed to displacement by newer AI tools. Reviewers note the aging TIFF-conversion workflow and that Takeoff Boost is still maturing. Deep-pocketed but slow-moving. Pricing is quote-driven and bundle-based, which can obscure the true cost of takeoff alone.
Integrates with
Integrates with Quick Bid and other ConstructConnect estimating tools, plus its own project-leads database. Connects across the ConstructConnect ecosystem.
Who it's for
Commercial subs, GCs, and suppliers already in the ConstructConnect/On-Screen Takeoff ecosystem, or those who want leads and takeoff from one vendor.
Features
✓ AI Takeoff Boost✓ Leads + Takeoff Bundle✓ Established BaseManual-Takeoff CoreQuote-Driven Pricing
Ownership & funding
On-Screen Takeoff dates to the 1990s; owned by Roper Technologies (NYSE: ROP) since 2016. Bundles takeoff with a project-leads data business. PlanSwift also sits in ConstructConnect's legacy digital-takeoff tier.
A suite of established takeoff and trade-estimating tools: PlanSwift for general takeoff, AutoBid for mechanical and sheet metal, and Accubid for electrical. The deep MEP estimating databases behind Accubid and AutoBid — Accubid Classic alone carries 40,000+ items with NECA labor factoring — are a genuine moat and remain a standard in larger MEP shops.
What it doesn't do
Core products are manual and database-driven; AI assistance is only beginning to emerge. The desktop and enterprise heritage means a heavier, less modern experience than the cloud-native newcomers, and reviewers cite a steep learning curve and setup effort. PlanSwift's older 32-bit architecture draws complaints about stability on large plan sets. Accubid and AutoBid are quote-based enterprise products with non-transparent pricing.
Integrates with
Accubid links to Trimble LiveCount for graphical takeoff and to TRA-SER and Supplier Xchange for pricing. Excel export across the suite. Integrates within the Trimble ecosystem.
Who it's for
Mid-to-large MEP subs and GCs that rely on deep, established electrical and mechanical estimating databases and can invest in training.

Public company (NASDAQ: TRMB), based in Westminster, CO. A serial construction-tech acquirer — and a plausible future buyer of AI-native takeoff startups. PlanSwift offers a one-time license option; Accubid and AutoBid are enterprise quote-based.
How to Use This Guide
Use this guide as a set of questions, not a verdict.
Is there a tool built specifically for your trade, such as Division 8, concrete, MEP, electrical, HVAC, plumbing, or drywall? Or do you need a multi-trade generalist because your estimating team touches many scopes?
How clean are the plan sets you usually receive? AI-forward tools can save significant time on clear plans, but dense, scanned, or messy drawings still need careful review.
Do you need takeoff only, or takeoff and estimating software that carries quantities into pricing? How much does takeoff software cost for your team size after add-ons, onboarding, and annual billing? Are you comfortable adopting a newer, well-funded tool with less history, or do you prefer an incumbent with broader integrations?
AI-forward tools can reduce manual work on the right plans, but vendor accuracy and time-savings figures should be tested. Manual-forward and AI-assisted incumbents offer maturity and integrations while their AI features continue to develop.
The safest evaluation is a trial on your own real plan sets. For the workflow distinction, read Takeoff vs estimate vs proposal: where the work actually breaks down for subs. For decision support, read the construction software FAQ article.
Closing
This guide is non-ranked and should be updated quarterly. Funding rounds, acquisitions, pricing, AI features, supported trades, and product maturity can change quickly in construction takeoff software.

Eliminating Manual Errors in Construction Bids
Common questions about reducing errors and improving accuracy
What causes most manual errors in subcontractor bids?
Manual errors usually come from disconnected workflows — things like outdated spreadsheets, inconsistent templates, or rekeying the same data multiple times. When project info lives across emails, texts, and PDFs, small mistakes add up fast.
How can software help reduce bidding mistakes?
Purpose-built estimating software automates repetitive tasks like data entry, quantity takeoffs, and revision tracking. Instead of chasing down the latest drawings or retyping costs, your team works from one centralized, accurate system — cutting errors before they happen.
Is automation complicated to set up for small subcontractors?
Not with modern tools like Riffle. You can connect your email or ITB inbox in minutes, and automation starts working behind the scenes — identifying bid invites, tracking updates, and helping you prioritize the right opportunities. No IT department required.
How much time can automation actually save?
Most subcontractors save 6–10 hours per week just by eliminating manual re-entry and version confusion. That’s more time for estimating the next job, reviewing margins, or simply getting home on time.
Does automating bids mean losing control over pricing?
Not at all. Automation handles the busywork — you keep full control over pricing, scope, and judgment calls. Think of it as an assistant that gets the numbers right so you can focus on strategy.
How do I know if my team is underspending or overspending on software?
A good rule of thumb: most subcontractors invest 1–3% of annual revenue in digital tools. If you’re still running bids manually or using outdated systems, the real cost might be hidden in lost time and missed opportunities.
Why does accuracy matter so much in bidding?
Every error compounds — one missed line item or miscalculated rate can erase your entire profit margin. Accuracy doesn’t just win jobs; it protects your business from losses you don’t see coming.
How does Riffle help subcontractors eliminate manual work?
Riffle automates your bidding and project workflows from start to finish. It finds ITBs in your inbox, organizes bid invites, fills in estimating data, and tracks updates — helping subcontractors bid smarter, reduce errors, and grow revenue.
We Understand the Bottlenecks for Subs
My biggest weakness has always been follow-ups—I’m just not great at it. If I had a built-in reminder feature to follow up on projects automatically, that would be a game-changer. I’ve gotten better, but I could still use that extra nudge.
Bryan Dolgin
Project Manager, Division 10 subcontractor
Quoting can be chaotic. You have five different contractors sending out the same bid invite, each named differently. We end up with duplicate bids on the board or miss one entirely because it was labeled another way. There is no clear procedure when invites come in from multiple people.
