Building Automation Estimating Software: 7 Picks for 2027

Short answer: pick the category before the vendor

Building automation estimating software, as this guide uses the term, is software that automates the estimating steps for construction and trade contractors: takeoffs from plans, pricing, proposals, and the handoff into the job. It does not mean building controls such as HVAC sequencing. TL;DR: if your estimators spend most of their week measuring plans, start with a takeoff-first tool such as STACK, Togal.AI, or PlanSwift. If the estimate has to become the job budget, invoices, and change orders in one system, start with JobTread, Procore, or Contractor Foreman. Bluebeam is a measurement layer that can sit under either path. For a broader category view, read our construction estimating automation comparison.

Regular estimating use: just over 85% of respondents according to BuiltWorlds (2026). That share was up from roughly 70% the year before, so for most small firms the open question is which tool fits, not whether to use one.

Key Takeaways

• Takeoff-first tools (STACK, Togal.AI, PlanSwift) are the shortest path when measuring plans is the bottleneck.

• Job-linked platforms (JobTread, Procore, Contractor Foreman) suit firms that want estimates to carry into the job record.

• Bluebeam publishes four annual per-user tiers, but the pricing text we read does not describe cost catalogs or proposals.

• Procore publishes no list price; its fee is set per product from Annual Construction Volume.

• Confirm export or API access in every candidate before you design any automation, because this guide did not verify API access for each vendor.

• We did not score ProEst or Buildertrend, because their vendor pricing pages could not be opened during this review.

Who this is for

This guide is for an owner or operations lead at a small construction or trade business who is close to choosing and wants a shortlist that matches how bids are built today. It is less useful for a multi-division general contractor shopping for enterprise preconstruction suites. If you want trade-specific detail first, see our electrical contractor guide or our landscaping guide.

Red flags: no one on your team will own the price list or cost catalog; most bids arrive as paper plans nobody will scan or upload; you expect software alone to replace estimator judgment on unusual scopes.

How we evaluated these tools

We weighted six criteria. The weights below are our analysis, not vendor data. Every price and feature in this guide comes from a vendor page we opened during this review, and review-site ratings were not used as scoring inputs.

Feature matrix: what each vendor page says it does

Blank or "Not described" cells mean the vendor text we read did not say. "Not listed" means the page did not show a free trial or free tier.

Our analysis of the matrix: the takeoff-first tools differ mostly on how much measurement they automate, while the platforms differ on what happens after the estimate is accepted. Procore and JobTread name the job-side features on their own pages; Contractor Foreman lists estimates but does not say which plan includes them. We are not in this table. Our role sits above whichever tool you choose, as the workflow section explains.

Pricing as published

Pricing checked October 16, 2026. Figures below come only from vendor pricing pages, and each one is cited in the sentence that follows the table. "Quote-based" means the vendor page did not publish a price.

STACK's plans run as low as $49 to $348 per user a month according to STACK (2026). The Takeoff & Estimate plan sits at $299 in that range, the Build & Operate plan includes a two-week free trial, and the page does not state the billing period for any plan.

Togal.AI's Growth plan is $299 per user a month according to Togal.AI (2026), billed yearly, with unlimited automated takeoffs. The Business tier for teams of four or more users is quote-based, and the page lists no free trial; its buttons lead to demo booking.

Bluebeam's four tiers run from $260 to $590 per user a year according to Bluebeam (2026), all paid yearly. Core is $330, and the page routes large organizations to Contact Sales.

JobTread's base subscription is $199 a month plus $20 per user according to JobTread (2026), with annual per-user rates falling from $16 to $4 as headcount grows, and the page says all features are included.

PlanSwift's Essential plan costs $2,000 a year for one seat according to PlanSwift (2026). The Core plan adds Auto Takeoff at $3,000 a year, and the free trial requires no credit card.

Contractor Foreman's Basic plan is $49 a month on annual billing according to Contractor Foreman (2026). Plans are flat for the whole company rather than per user, and the Unlimited tier is $332 a month on annual billing or $399 monthly.

Procore publishes no list price for its estimating product, according to Procore (2026): the fee is an upfront annual amount set per product from Annual Construction Volume, and buyers request a custom quote.

Contractor Foreman's published tiers, using the same page as the sentence above:

Our read on pricing: a per-seat plan such as PlanSwift's suits one or two estimators, while a flat company plan such as Contractor Foreman's can be cheaper as headcount grows if its tier fits. Both models need the vendor's written confirmation of billing terms before you compare.

Vendor profiles

Each profile separates vendor facts from our read. The vendor facts come from the pricing and product pages named in the matrix and pricing sections.

STACK

Vendor facts: three listed plans, with takeoff, estimates, and proposals in Takeoff & Estimate, field tools in Build & Operate, and a Full STACK Platform that uses a "Build Your Price" tool. Our read: a good fit for a firm whose bottleneck is plan measurement and that wants estimating and bidding in one tool. Limitations: the billing period is not stated, and the full-platform price depends on configuration. Implementation: start with one estimator on the Takeoff & Estimate plan, run one real bid end to end, then decide whether field tools are needed. Evidence: STACK pricing page.

Togal.AI

Vendor facts: the Growth plan includes unlimited automated takeoffs, chat prompts, image and symbol searches, and external collaboration; the Business tier adds onboarding, a dedicated representative, a classification library template, and SSO. Our read: best for takeoff-heavy estimators who want automated counts. Limitations: no free trial is listed, and the page we read describes no proposal features. Implementation: confirm your symbol and classification needs before buying, since the Business tier is quote-based. Evidence: Togal.AI pricing page. Procore's estimating page also names Togal.ai among its integrations, so check which handoff path your team would use.

Bluebeam

Vendor facts: Basics covers basic length and area only; Core adds perimeters, counts, angles, and volume; Complete adds Dynamic Fill and Quantity Link to Excel; Max adds Magic Markups. Our read: a good fit for crews that already work from PDF plans and need precise measurements. Limitations: the pricing text does not describe cost catalogs or proposals, so you will need another tool for pricing. Implementation: decide early how measurements move into your spreadsheet or estimate. Evidence: Bluebeam pricing page.

JobTread

Vendor facts: a flat base plus per-user pricing, with Estimating, Takeoff, Contracts and eSignatures, Cost Catalog, and Bid Requests listed under Sales & Estimating, and job costing, change orders, and purchase orders listed separately. Our read: a strong fit when the estimate must link to job costing and change orders. Limitations: the page names Bid Requests without describing how they work, and its platform totals are vendor claims rather than independent figures. Implementation: move one active job into the cost catalog before you move the whole company. Evidence: JobTread pricing page.

Procore Estimating

Vendor facts: takeoff from 2D or 3D models, a customizable database of parts, assemblies, and equipment, AI detection of floor plan areas and repeated symbols, embedded cost catalogs, customer-facing proposals, and a handoff from estimate to bid to contract and financials. The page names more than 500 integrations, including Sage 100 Contractor Connector, Compass, and Togal.ai. Our read: a fit for firms already on Procore, or firms that want estimate-to-contract in one vendor. Limitations: pricing is custom and depends on annual construction volume, and the path to a number is a demo. Implementation: confirm which Procore modules you need before scoping. Evidence: Procore Estimating page.

PlanSwift

Vendor facts: Essential at $2,000 a year for one seat includes takeoff and estimating with pre-built trade assemblies, plus Auto Count, Auto Scale, and Auto Bookmark; Core adds Auto Takeoff; volume pricing for teams of 10 or more is quote-based. Our read: the cleanest fit for one estimator who needs fast takeoff without a platform. Limitations: Auto Takeoff is only on Core, and the page describes no job-side features. Implementation: run the free trial on one live plan set and time the takeoff before deciding. Evidence: PlanSwift pricing page.

Contractor Foreman

Vendor facts: flat company pricing by user cap, from one user up to unlimited, with "Estimates" listed as a feature. The text we read does not say which tier includes estimating. Our read: a fit for a small firm that wants one flat bill and a single system for scheduling and job records. Limitations: confirm in writing which tier includes estimating before you buy. Implementation: ask the vendor to walk through one of your existing estimate templates in a demo, and get the cancellation terms in writing before committing. Evidence: Contractor Foreman pricing page.

ProEst and Buildertrend are not scored here. Their vendor pricing pages could not be opened during this review, and we did not want to print figures from third-party listings.

Where the pain lives: scope changes and bid follow-up

Estimates lose value between the proposal and the contract. Scope changes that never reach the estimate are where margins leak, and our scope change tracking guide covers that problem in more depth. Labor pressure makes the problem harder to ignore: Firms using AI or planning more AI spend: 61% according to Sage (2026), up from 44% the year before.

Here is a proposed, configurable workflow that US Tech Automations could build above a tool such as the ones in the matrix, once that tool's export or API access is confirmed. The trigger is an estimate's status changing to sent in the estimating tool. The action reads that estimate's line items through the tool's export or API, compares them with the last approved version, and flags price or quantity changes. The output is a change-tracking record and a task for the estimator. Prerequisites: the estimating tool must export or expose line items, and someone must own the mapping of cost categories between the estimate and your accounting system. Human review point: an estimator approves any flagged change before anything reaches the client, and your team sets the threshold that triggers a flag.

A second proposed workflow handles accepted bids. The trigger is a proposal marked accepted. The action creates a job record in your job or accounting system with the estimate's cost categories, and the output is a kickoff task list for the project lead. Prerequisites are write access to the job system and an agreed cost-category list. Review points: a person confirms cost codes before the first invoice, and someone confirms the contract value matches the accepted proposal before the job record goes live. Neither workflow describes a deployed setup or a measured result; both are designs to scope against your own tools.

Build it yourself in Zapier, Make, or n8n?

Many small firms will stitch this together in Zapier, Make, or n8n, and that is a fair option. Zapier's help center documents run history, replaying failed tasks from Zap history, custom error paths that appear as Handled error, and a Troubleshoot tab for errored steps (Zapier help). Those features can support retries, error branches, and audit evidence when you configure them. Make and n8n offer similar building blocks, which we did not verify in this review. In every case the builder still owns idempotency, so a retried event does not create a duplicate job; escalation to a named person; access controls for stored credentials; and maintenance when a vendor changes its API.

Worked example, illustrative and not a customer: a four-person estimating team on STACK's Takeoff & Estimate plan, listed at $299 per user a month according to STACK (2026), would pay $1,196 a month at list, or $14,352 across 12 months, before any discount. If the team also wants three custom automations for proposal sent, bid accepted, and change order logged, a REST-hook build must read bundle.targetUrl at subscribe time and store it, as Zapier's hook-trigger docs describe, so the builder owns that bookkeeping for each automation.

A configured US Tech Automations design would change who owns those pieces: the proposed design names the review points, the escalation owner, and the access rules before the first run, using the same export prerequisites. Whether that beats a DIY build depends on how many events you need and who will maintain the workflow after launch.

When NOT to use US Tech Automations

A layer above your tools is the wrong buy in three cases. If you only need takeoff on a few plans a month, PlanSwift's free trial or Bluebeam's Basics tier is simpler than any workflow. If your whole company already runs Procore and its estimating module covers your bids, keep the handoff inside Procore. If your estimates are still on paper and nobody will commit to a price list, fix the estimate process before you automate its handoffs.

Glossary

• Takeoff: the counted list of quantities measured from plans, such as wall length, fixture count, or area.

• Assembly: a grouped set of materials, labor, and equipment priced together, such as a single wall type.

• Cost catalog: a stored list of unit costs that estimates pull from.

• Alternate: a priced option the client can accept or decline on the proposal.

• Annual Construction Volume (ACV): the revenue measure Procore uses to set its annual fee.

• REST hook: a webhook subscription in which a platform calls a stored, per-automation URL when an event happens.

Decision checklist

• Measure the week: do your estimators spend most of their time on takeoff, or on pricing and proposals?

• Name the system the accepted estimate must feed, and the format it needs.

• Ask each shortlisted vendor for billing period and seat rules in writing before you compare.

• Confirm export or API access for the one or two tools you shortlist.

• Name the owner of the cost catalog before the trial starts.

• Decide who approves any change that reaches a client.

Frequently asked questions

Is building automation estimating software the same as building automation controls?

No. In this guide it means estimating software for construction and trade contractors, not HVAC or lighting controls.

Which tools publish prices you can check without a sales call?

STACK, Togal.AI, Bluebeam, JobTread, PlanSwift, and Contractor Foreman publish figures on their pricing pages, and Procore publishes none for its estimating product.

Do any of these tools offer a free trial?

PlanSwift offers a 14-day free trial, and STACK's Build & Operate plan has a two-week trial. The Togal.AI page lists no trial.

Can Zapier replace an estimating tool?

No. Zapier moves data between systems and can route approvals, but takeoff and cost data still need an estimating tool.

Will these prices hold through 2027?

They are not guaranteed. Prices here were checked on October 16, 2026, and vendors change their pages, so confirm any figure in writing before you budget.

Next step for a small firm

The category decision comes first: takeoff-first tools for measurement-heavy estimators, and job-linked platforms when the estimate has to become the job budget. Shortlist two tools from the matrix, confirm their export or API access and billing terms in writing, and run one real bid through each before you sign.
