A construction estimate needs more than a polished proposal. Someone must explain where the quantities came from, which drawing revision was measured, what labor and material assumptions were used, and what was deliberately excluded. Software becomes valuable when those explanations survive the next revision and the handoff to delivery.
STACK, PlanSwift, Buildxact, Clear Estimates, and Procore Estimating support different parts of that process. Some begin with detailed takeoff; others emphasize reusable cost libraries or the connection between estimating and the build. This comparison uses official information checked October 15, 2026, with no claimed hands-on testing, bid accuracy benchmark, or guaranteed savings.
Define the decision as quantities through priced scope. Our proposal software comparison addresses presentation and acceptance once the scope is known. Our procurement guide covers purchasing authority and supplier orders after the business decides what it needs to buy.
Compare takeoff, pricing, and handoff
| Product | Best fit | Main strength | Meaningful tradeoff |
|---|---|---|---|
| STACK | Shared drawing-based estimates | Connected takeoff and estimating | Full platform and estimating have different prices |
| PlanSwift | Trade-specific estimating routines | Assemblies with takeoff tools | Essential and Core differ in AI scope |
| Buildxact | Builders joining estimate to job work | Takeoff, quoting, and operational handoff | Free credits and paid plans serve different scopes |
| Clear Estimates | Repeatable remodeling estimates | Line-item database and templates | Database rates still need local judgment |
| Procore Estimating | Connected construction teams | Estimate context within a wider platform | Annual contract and product scope need a quote |
STACK
STACK connects drawing measurement with labor and material estimates and proposals. Its published offering includes takeoff, custom items and assemblies, and collaboration around plans. That makes it a relevant option when multiple people need to work from a shared set of quantities rather than exchange disconnected spreadsheets.
The strength is continuity between what was measured and what was priced. The limitation is that collaboration still needs agreed rules for drawing versions, naming, waste allowances, and ownership. Have two estimators review a revised sheet and explain whether a changed quantity affects one line or an entire assembly. Shared access alone does not settle that question.
The pricing overview lists Takeoff & Estimate from $299 per user per month. Build & Operate is a separate offering from $49, while the full platform is listed from $348. Confirm the billing commitment, user minimums, and exact package before annualizing those starting figures. STACK suits teams that want a shared estimating workspace and can maintain a consistent item and assembly library across jobs.
PlanSwift
PlanSwift combines takeoff and estimating with prebuilt assemblies and trade-oriented tools. Its current pricing page distinguishes Essential from Core: both include the estimating foundation, while Core adds the fuller Takeoff BOOST suite and Auto Takeoff. A buyer should examine that present lineup instead of relying on older perpetual-license descriptions.
The advantage is developing an estimating routine around repeatable trade assemblies. The limitation is that an automated first pass remains an input requiring review. Ask an estimator to check scale, openings, duplicated symbols, and a changed detail before accepting quantities. Then modify an assembly’s labor assumption and inspect every affected estimate line.
Essential is currently $2,000 per year for one seat, and Core is $3,000 per year for one seat; the page mentions discounted additional seats. These are annual subscriptions including updates, support, and training, rather than an ownership purchase. Confirm workstation requirements, activation, extra-seat terms, and any separate extensions. PlanSwift fits estimators who can invest in maintaining reusable assemblies and want the measured quantities connected to their costing process.
Buildxact
Buildxact connects estimating and digital takeoff to quoting and, in higher plans, job management. Its US pricing page also describes dealer connections, purchase orders, and a mobile job workflow. This makes it worth considering for builders who need to carry an accepted estimate into the work rather than recreate the budget elsewhere.
The benefit is a clearer handoff between the person pricing the job and the team running it. The limitation is that the free Go offering is credit-based and does not represent the complete paid takeoff and job-management workflow. Test the required features together and identify which AI assistants are included versus optional.
Foundation lists $199 monthly or a displayed $169 monthly equivalent on annual billing, with an annual total of $2,030. The rounded monthly equivalent should not be multiplied as an exact invoice calculation. Annual plans require a 12-month commitment; the page states unlimited users for Foundation and lists higher plans and add-ons separately. Confirm regional taxes and commercial terms. Buildxact suits smaller building operations that want an estimate-to-job process and can standardize its handoff.
Clear Estimates
Clear Estimates emphasizes an estimating library and reusable templates, with a published database of more than 13,000 line items and quarterly labor and material rate updates. That can be a useful starting point for remodeling work where similar scopes recur and the estimator needs a consistent way to build a price.
The strength is repeatability without constructing every estimate from a blank sheet. The limitation is that a database is not a supplier quote or a guarantee of local conditions. Inspect representative lines against your actual costs, access constraints, subcontractor arrangements, and waste assumptions. Keep a clear distinction between a default template and the job-specific adjustments that make it usable.
Standard is $79 per month on monthly billing or $59 per month billed annually; Pro is $119 monthly or $99 on annual billing. Pro adds capabilities including plan/image uploads and integrations, and additional users are listed at $9 per month. Confirm term and renewal rules despite the page’s general no-contract wording. Clear Estimates fits firms whose main need is a maintained remodeling estimate structure with a manageable pricing library.
Procore Estimating
Procore Estimating puts takeoff and estimating within a broader construction platform. Its product page describes drawing quantities, cost catalogs, and estimate workflows. This is especially relevant when accepted scope must reach the people responsible for project budgets and delivery without losing its original structure.
The advantage is a connected operating environment for estimating and the wider project. The tradeoff is buying and implementing a broader platform when the immediate problem might be one estimator’s takeoff process. Ask the vendor to demonstrate the exact handoff from estimate to project budget, including exclusions, alternates, and a later revision. Confirm which modules are necessary for that demonstration.
Procore pricing is custom, based on selected products and annual construction volume, with an upfront annual fee. Its model includes unlimited users, so a per-seat estimate would misrepresent the commercial structure. Obtain the definition of billable construction volume, implementation scope, and renewal assumptions in writing. Procore Estimating suits organizations that already need, or deliberately want, a connected construction management environment with shared access across stakeholders.
Evaluate a revised drawing, not only a clean first bid
Choose a representative job with one detailed drawing, a repeated assembly, and an exclusion that matters commercially. Measure the initial scope and prepare a priced estimate. Record units, labor productivity, waste, markups, taxes, and the revision identifier so that another estimator can explain the result without asking its author.
Next, replace one sheet and change a supplier price. Check which quantities and assemblies require review, whether accepted alternatives remain visible, and how the proposal changes. Preserve an explanation of the difference between the initial bid and revised bid. An attractive total is much less useful when nobody can identify the cause of its movement.
For the handoff, ask a project manager to locate the allowance for a specific material and explain the corresponding scope. If they must rebuild the estimate in another format, include that work in the purchase decision. Cost-library maintenance, permissions, training, and accounting handoff are recurring responsibilities, not one-time setup details.
- Confirm supported drawing formats, scale checks, and revision handling.
- Document who owns assemblies, local rates, and supplier updates.
- Separate automated quantity suggestions from estimator-approved scope.
- Price the actual users, modules, add-ons, term, and implementation.
- Check export quality and the accepted-estimate handoff.
Shortlist STACK for shared takeoff, PlanSwift for trade assemblies, and Buildxact for a builder’s estimate-to-job workflow. Consider Clear Estimates for repeatable remodeling costs and Procore for a connected project platform. Select the option that lets a second person explain both the quantity and the assumptions behind the final price.
