STACK vs PlanSwift: Takeoff Tool Comparison 2026

Both STACK Takeoff & Estimating and PlanSwift handle construction takeoff and estimating. Both work from PDF plans. Both have assembly libraries and export to estimating workflows. The differences come from how each platform handles your team's day-to-day workflow and what kind of operation you run.

Who They Serve

STACK targets contractors who want a cloud-based takeoff and estimating platform. The free plan brings in small GCs and subs testing the workflow. The paid tiers fit mid-sized GCs, residential builders, and specialty subs who need multiple estimators working in one shared library.

PlanSwift targets contractors with established Windows-based workflows. Mid-sized GCs and trade contractors with desktop-first IT setups are the core customer. The product has been around since the mid-2000s and many estimators learned takeoff on it.

If your team works from laptops in coffee shops and on jobsites, STACK fits the deployment model. If your estimators sit at desktop workstations with dual monitors and a stable IT footprint, PlanSwift fits the operating environment.

Deployment and Setup

STACK runs in a browser. No install, no IT request, no licensing seats to manage. An estimator logs in and starts taking off. New hires get access within minutes. Plans upload to a shared cloud library and the team works from the same source.

PlanSwift installs on Windows. Each user gets a license tied to a machine. Plan files live on a shared drive or network folder. If your IT team manages workstations, PlanSwift fits the existing setup. If the firm wants to skip the desktop layer, STACK saves the work.

Collaboration

STACK supports multiple estimators. Two people can work on the same takeoff at the same time. Plans live in a shared library so any team member can pick up where another left off. Comments and markups stay attached to the plan.

PlanSwift is single-user at the file level. Two estimators can't work on the same takeoff at the same moment without overwriting each other's work. Teams divide work by trade or by drawing sheet and merge the results in Excel or in the estimating tool. For a solo estimator or a firm where one person handles each bid, this is fine. For larger teams, the workflow adds friction.

Estimating Integration

STACK includes estimating in the same product. The takeoff feeds into the estimate without an export step. Assemblies pull labor and material costs from a database that the team maintains. STACK generates bid summaries, markup, and proposals in the same app.

PlanSwift was built takeoff-first. Estimating happens through tight integration with Excel. The takeoff sends quantities to a linked spreadsheet where the estimator applies labor and material costs. Many estimators prefer the Excel model because they know it and the spreadsheets are portable. Others find the back-and-forth slows them down compared to an all-in-one tool.

Learning Curve

STACK uses a modern web UI. New estimators ramp up in days. The interface fits the cloud era, with labels on every button, a linear workflow, and a searchable help center.

PlanSwift uses a desktop UI that has accumulated features over 15+ years. Power users move fast. New users face a steeper ramp. Training videos and a user community fill the gap, but expect a few weeks before a new estimator runs solo.

Pricing

STACK offers a free tier with limits on number of takeoffs and users. Paid tiers scale with users and feature access. Subscription pricing, no perpetual license.

PlanSwift sells annual subscriptions. The price runs higher per seat than STACK's mid-tier plan. No free version. Trade-specific plug-ins cost extra.

The Verdict

Pick STACK Takeoff & Estimating if you want cloud-based takeoff, multiple estimators working in the same library, an integrated estimating module, and a free way to start before committing to a paid tier.

Pick PlanSwift if your team has an established desktop workflow, uses Excel for estimating, and prefers the depth of a tool refined over 15+ years.
