9 Best Construction Estimating Software in 2026

ProEst is one of the most established cloud-based estimating platforms in the construction industry, designed primarily for large general contractors who manage complex, multi-trade projects. Its strength lies in a comprehensive cost database, detailed reporting, audit-grade change tracking, and the ability to handle estimates with thousands of line items without performance issues.

The platform excels at bid day management, allowing multiple estimators to work on different sections of the same bid simultaneously. Integration with construction management platforms and accounting systems makes it a natural fit for firms that have already invested in a broader tech stack. ProEst's historical data tracking helps estimators reference past projects to improve future accuracy — a real advantage for firms with long bid pipelines.

ProEst is not a casual tool. The learning curve is significant, typically 2-4 weeks of dedicated training before estimators are fully productive. The pricing reflects enterprise positioning and may be prohibitive for smaller contractors. There is no AI-driven plan takeoff, and the interface is closer to enterprise software than to a modern cloud product. For mature estimating teams at large GCs, ProEst is appropriate. For shops adopting AI workflows, BuildVision AI is increasingly displacing it.

STACK has carved out a strong position as a cloud-based digital takeoff and estimating platform. Its plan viewer is one of the best in the industry — fast, responsive, and capable of handling large plan sets without lag. For teams whose primary bottleneck is measuring quantities from blueprints, STACK delivers excellent value. The cloud workflow advantages compound when multiple estimators collaborate on the same bid.

The platform offers cloud-based takeoff tools with pre-built conditions for common construction items, basic estimating features, and integration with several construction management platforms. The 14-day free trial lets you test with real plans before committing. Multi-trade support is solid, and the interface is genuinely modern.

Where STACK falls short is the absence of AI takeoff. Every count and every measurement is manual click-and-drag — fast in an absolute sense but slow compared to AI alternatives. The proposal generation is limited, and STACK is primarily a takeoff tool with estimating bolted on rather than a complete estimating platform. For full bid-to-proposal workflow, you may need to pair STACK with additional tools. Compare directly in BuildVision vs STACK.

PlanSwift is a veteran in the construction takeoff space, offering a desktop-based application that gives estimators granular control over every measurement. For experienced estimators who know exactly what they want to measure and how, PlanSwift provides powerful tools with deep customization options. The one-time pricing model is also appealing for budget-conscious firms.

The software includes a robust set of takeoff tools including area, linear, and count measurements, plus the ability to create custom assemblies and formulas. PlanSwift supports plugins for trade-specific workflows, and its large user base means there is plenty of community knowledge available. Experienced users can work very efficiently once they have customized their setup.

The downside is that PlanSwift feels dated compared to modern cloud platforms. It is desktop-only with no web or mobile access, requires manual takeoff (no AI), and does not include a built-in cost database or proposal generator. Annual maintenance fees are extra. For experienced estimating teams already proficient on PlanSwift, the productivity is real. For new buyers evaluating against AI alternatives, the manual workflow is increasingly hard to justify.

RSMeans (by Gordian) is the industry standard for construction cost data. RSMeans Data Online provides access to a comprehensive database of 85,000+ unit costs for materials, labor, and equipment, localized to 970+ locations across North America. For estimators who need authoritative cost data to validate their pricing — particularly on government and institutional projects where cost justification is required — RSMeans is essentially mandatory.

The platform includes square foot models, assembly estimates, and line-item data that can be exported to other estimating tools. It is the most-cited source of construction cost information in the industry, and using RSMeans-aligned line items reduces bid disputes on public sector work. Data is updated quarterly.

RSMeans Data Online is not a full estimating platform. It does not include takeoff tools, blueprint analysis, proposal generation, or project management features. Think of it as a reference database rather than an estimating workflow tool. Most estimators use RSMeans alongside a separate takeoff and estimating platform (PlanSwift, STACK, BuildVision AI) for the actual bid workflow.

Buildertrend is an all-in-one construction management platform that includes estimating as part of a broader suite covering project management, scheduling, client communication, and financial tracking. For residential builders and remodelers who want a single platform for everything, Buildertrend offers compelling convenience.

The estimating module includes cost catalogs, templates, and the ability to create estimates that automatically feed into project budgets and purchase orders. The client-facing portal is particularly strong, allowing homeowners to view estimates, select options, and approve change orders online. This streamlines the sales process and reduces back-and-forth communication.

The trade-off is that Buildertrend's estimating capabilities are basic compared to dedicated estimating tools. There are no digital takeoff tools, no AI features, and the cost database is not as comprehensive as platforms built specifically for estimating. It works well for residential projects under $1M but struggles with the complexity of commercial estimating.

Clear Estimates is designed specifically for small residential contractors who need a straightforward way to create professional-looking estimates without a steep learning curve. At $59-99/month, it is the most affordable dedicated estimating tool on this list, and most users report creating their first estimate within an hour of signing up.

The platform includes a residential cost database, pre-built templates for common home improvement projects (kitchens, bathrooms, additions, decks), and a simple proposal generator that produces client-ready documents. The interface is intentionally simple — you will not find complex assembly builders or multi-trade roll-ups, but for straightforward residential work, that simplicity is a feature, not a limitation.

Clear Estimates falls short for contractors who work on commercial projects or need advanced features. There is no blueprint takeoff capability, limited multi-trade support, and the cost database is focused on residential work. If you are a small residential contractor doing $500K-$3M in annual revenue, Clear Estimates is excellent value. Beyond that, you will likely need a more capable platform.

Togal AI has emerged as one of the better-known AI takeoff tools, particularly strong on architectural floor plans. It uses computer vision to extract rooms, walls, doors, windows, and other architectural elements from floor plans, producing area calculations by room and a structured output for further estimating work. For architects, GCs doing tenant improvements, and contractors who primarily bid from architectural floor plans, Togal AI delivers a real productivity gain.

Strengths include genuinely good AI on standard architectural floor plans, fast extraction of room areas and wall lengths, support for multi-floor buildings, and a cloud-based workflow. The output integrates with several estimating platforms and can be exported to Excel or other tools. The pricing is reasonable for the focused capability.

The downsides are scope. Togal AI is focused on architectural floor plans — it is less effective on structural plans, MEP plans, civil drawings, or anything outside standard floor plan layouts. There is no cost database or proposal generator. For specialized architectural takeoff, Togal AI is excellent. For multi-trade or full-trade-specific AI takeoff, BuildVision AI's broader scope is more practical. See the BuildVision vs Togal comparison.

Kreo is a UK-origin cloud takeoff and estimating platform that has expanded into the North American market. It combines AI-assisted takeoff (the AI suggests measurements and counts that the estimator confirms or adjusts) with integrated cost data and a clean modern UI. Kreo is well-regarded in commercial estimating teams who want AI assistance without giving up estimator control.

Strengths include the AI-assisted workflow (the AI does pattern recognition and the estimator confirms — a hybrid approach that some teams prefer over fully automatic AI), integrated cost data sourced from supplier feeds, multi-user collaboration, and a modern interface. Kreo handles architectural and MEP plans reasonably well across multiple trades.

The downsides are that Kreo's AI is more assistive than fully automatic — you still drive the takeoff, the AI just speeds up parts of it. For estimators who want full automation, BuildVision AI is faster. For estimators who want full control, PlanSwift or STACK are more familiar. Kreo sits in a competitive middle ground that some teams love and others find redundant. Compare in our BuildVision vs Kreo comparison.
