STACK Alternatives in 2026: The Best Construction Takeoff & Estimating Tools

Q: Does STACK have AI takeoff?

Yes, through STACK Assist and, as of 2026, STACK IQ, which drives takeoff and estimating from natural-language prompts. Several alternatives are AI-native, including Quotr.ai and Togal.

STACK has been a cloud takeoff and estimating staple since 2000, and it is good at what it does: fast on-screen takeoff, a deep assembly library, and, as of 2026, AI through STACK IQ. Teams go looking for a STACK alternative for a few specific reasons: the annual-contract pricing (roughly $2,599 to $2,999 per user per year, with some users reporting renewal increases), a learning curve, or the fact that STACK stops at takeoff and estimating and leaves procurement and done-for-you work to other systems.

This guide ranks six alternatives worth comparing in 2026, who each is genuinely for, and where each falls short. The short answer: for most teams the strongest all-in-one alternative is Quotr.ai, because it covers the full path STACK leaves unfinished, AI takeoff to estimate to procurement, with a done-for-you desk on top. But the right pick depends on what you actually need next.

Why teams look for a STACK alternative

STACK does its core job well, so the reasons to shop around are usually about scope, pricing model, or fit:

It ends at the estimate. STACK covers takeoff and estimating, but procurement, material sourcing, and done-for-you estimating live in other systems.
Annual-only pricing. Plans bill yearly (about $2,599 to $2,999 per user), a bigger commitment than a monthly option, and some reviewers report renewal quotes rising above the first-year price.
Learning curve. Reviewers praise the depth but note it takes time to get fully productive.
A different trade or workflow focus. Some teams want AI tuned to a specific trade, a desktop license, or a fully outsourced option. A good STACK alternative keeps what is great about STACK, fast and accurate takeoff, and closes whichever of those gaps matters to you.

The 6 best STACK alternatives in 2026

1. Quotr.ai — best all-in-one (takeoff, estimating, procurement, and a done-for-you desk)

Where STACK hands you off once the estimate is done, Quotr.ai keeps going. Upload a PDF set and its AI auto-counts every item with a confidence score and an audit trail back to the sheet, at 95 to 99% accuracy on clean vector PDFs in internal benchmarking. Those quantities flow into a priced estimate, then into bids, then into a factory-direct procurement layer that turns the number into bought materials. Two things STACK has no answer for round it out: an AI assistant you can ask about your plans in plain language, and Quotr.ai Service, a desk of senior cost estimators who will run the bid and hand back a priced estimate when you would rather not touch it.

Best for: teams that want STACK-style takeoff plus the estimating, procurement, and done-for-you options STACK does not offer, billed monthly.
Pricing: Lite $79/seat per month, Plus $299, Enterprise custom; 7-day free trial.
Watch-out: newer than the incumbents (founded 2024); like all AI takeoff, edge cases get a human check, which Quotr.ai flags with confidence scores.

2. Togal.AI — best dedicated AI takeoff

If your only bottleneck is the takeoff itself, Togal.AI is the sharpest point solution here. It auto-detects rooms, areas, and finishes in the browser, which has made it a favorite among drywall, flooring, and paint estimators, then exports those quantities to whatever you price in. (For the one-to-one, see Quotr.ai vs Togal.AI.)

Best for: estimators who mainly want fast AI takeoff and are fine exporting to other tools.
Pricing: Growth plan around $299/user per month, billed yearly.
Watch-out: stops at quantities, no built-in pricing engine or procurement.

3. PlanSwift — best desktop, license-based takeoff

Prefer a desktop you own to a browser you rent? PlanSwift, now under Trimble, has been the point-and-click takeoff workhorse for years, with drag-and-drop assemblies and a recently bolted-on AI module called Takeoff Boost. The catch is that you give up everything the cloud-native tools do by default. (For the one-to-one, see Quotr.ai vs PlanSwift.)

Best for: estimators who want an offline desktop tool and are comfortable on Windows.
Pricing: roughly $1,749 to $2,000 per year (subscription since 2025); confirm with Trimble.
Watch-out: Windows only (no Mac, cloud, or real-time collaboration); reviewers report stability issues on large plan sets.

4. Bluebeam Revu — best for PDF markup plus manual takeoff

Bluebeam makes the list for a different reason than the rest: it is the PDF markup standard a huge share of the industry already keeps open all day. Its takeoff tools are precise but manual, and its AI lives in the newer Bluebeam Max tier rather than in the core product.

Best for: teams that live in PDF markup and want calibrated manual takeoff alongside it.
Pricing: subscription per user; Bluebeam Max around $590/user per year (intro).
Watch-out: manual-first, no native AI auto-takeoff without Max, and not an end-to-end estimating suite.

5. Procore Estimating — best if you already run Procore

Procore Estimating (once Esticom) is the easy call in exactly one situation: you already run Procore for project management and would rather estimate in the same suite than add another login. Outside that case, it is heavier than a focused takeoff tool needs to be.

Best for: teams standardized on Procore who want estimating in the same suite.
Pricing: custom / enterprise.
Watch-out: heavier and pricier than a focused takeoff tool if you are not already in the Procore ecosystem.

6. Beam AI — best for done-for-you, outsourced takeoff

Beam AI answers a different question than the software tools above: what do you do when nobody is free to run the takeoff? Built by Attentive.ai, it pairs fast automated takeoff with a done-for-you desk that returns QA’d quantities in 24 to 72 hours, so a staffing crunch stops being a reason to pass on a bid. (For the one-to-one, see Quotr.ai vs Beam AI.)

Best for: teams that want fast automated takeoff or to outsource broad scopes entirely.
Pricing: quote-based (not public).
Watch-out: returns quantities you still have to price; estimating and procurement live downstream.

How to choose a STACK alternative

Decide how far past takeoff you need to go. If you only want takeoff, PlanSwift, Bluebeam, or Togal may be enough. If you want takeoff through estimating, procurement, and buyout, Quotr.ai fits.
Check the pricing model. Annual contract versus monthly matters for cash flow. Quotr.ai is monthly with a trial; STACK, PlanSwift, and Togal lean annual.
Decide whether you want to run it or hand it off. If you have no estimator to spare, Beam AI or Quotr.ai Service do the work for you; the others are software you run.
Mind the gap after the count. A fast takeoff that still needs three more tools to bid and buy is not a full solution. That is the gap Quotr.ai is built to close. For the deep one-to-one comparison, see Quotr.ai vs STACK. For the AI-takeoff point tools specifically, see Togal alternatives. If you are mapping the whole category, our best AI construction estimating software guide covers it end to end, and Is AI takeoff actually accurate yet? is worth reading before you trust any tool’s numbers.

Frequently asked questions

What is the best STACK alternative in 2026?

For most contractors, Quotr.ai is the best all-in-one STACK alternative because it covers takeoff, estimating, procurement, and a done-for-you option in one platform, where STACK stops at takeoff and estimating. Togal.AI, PlanSwift, Bluebeam, Procore Estimating, and Beam AI are strong for narrower needs.

How much does STACK cost, and is there a cheaper alternative?

STACK bills annually, roughly $2,599 to $2,999 per user per year, with AI on the higher tier. Quotr.ai is a lower entry point at $79 per seat per month, billed monthly with a 7-day trial, and it adds procurement and a done-for-you option STACK does not include.

Does STACK have AI takeoff?

Yes. STACK offers AI through STACK Assist and, as of 2026, STACK IQ, which drives takeoff and estimating from natural-language prompts. Several alternatives are AI-native, including Quotr.ai and Togal.

Which STACK alternative adds procurement?

Quotr.ai is the standout: its procurement layer sources materials factory-direct, delivered door-to-door, so a priced estimate turns into bought materials. Most other tools, including STACK, do not include procurement.

Is there a free STACK alternative?

There is no permanently free, full-featured AI alternative, but Quotr.ai offers a 7-day free trial so you can run a real plan set before paying. Some tools offer limited free tiers for basic takeoff.

Which STACK alternative is best if I want the work done for me?

Beam AI and Quotr.ai Service both offer done-for-you takeoff. Beam returns QA’d quantities; Quotr.ai Service returns a priced estimate from senior cost estimators. The others are software you run yourself.
