Best On-Screen Takeoff Alternatives for Construction (2026)

ConstructConnect Started the Clock on On-Screen Takeoff

For most of three decades, On-Screen Takeoff was bought one way: you paid once, owned your license, and renewed maintenance if you felt like it. That deal built OST into the standard tool of commercial estimating departments, especially in drywall, framing, paint, and the rest of the interior trades. Thousands of estimators learned the job inside it.

In June 2026, the deal ended. ConstructConnect, which owns On-Screen Takeoff along with PlanSwift, Quick Bid, and QuoteSoft, began migrating OST perpetual license holders to subscription licensing, on a plan it spelled out in a help-center FAQ back in February: once your company is transitioned, your licenses for the old versions are disabled, and the licensing system that supported perpetual licenses is deprecated entirely by the end of 2026. From version 4.0.0.805 onward, the software is sold only as an annual subscription. And if you later stop renewing that subscription, the software still opens, but ConstructConnect states that Auto Takeoff, Auto Count, Auto Name, Auto Link, project sharing, and transformation tools shut off, and your projects go read-only.

That last clause is the whole story. The software you bought outright is becoming software you rent, and the rent is what keeps your own takeoffs editable. Every OST user now has a yearly decision to make, so ask it directly: if you are going to pay every year regardless, is On-Screen Takeoff still the right tool, or is 2026 the year to move?

On-Screen Takeoff is not a bad product. It holds a 4.4 rating on G2 across 150 reviews and 4.3 on Capterra across 155, reviewers consistently praise how fast condition-based takeoff is once your library is set up, a new build shipped earlier this month, and estimators on the forums were still calling it the gold standard for takeoffs as recently as last year. OST users are not searching for alternatives because the tool stopped working. They are searching because the company changed the terms, the price is quote-based and opaque, the application is Windows-only in a mixed-device industry, and the AI counting features now live behind a separate subscription with no published price.

For full transparency: we make Easy Takeoffs and we rank it first below. Every price in this guide was pulled from each vendor's official pricing page or, where a vendor hides pricing, marked as such, all verified in July 2026. We also call out where each competitor beats us, and where staying on OST is the right answer.

The Best On-Screen Takeoff Alternatives at a Glance

The table is the short version. The rest of the guide is the reasoning, including where every tool on it loses.

What Is Actually Happening to On-Screen Takeoff

The short version: the perpetual license is dead, the old versions are being unsupported in waves, and the features estimators care about most are now tied to continuous payment. The timeline makes it concrete.

The deal changed from owning to renting, and the power moved with it. Under the perpetual model, dropping maintenance meant losing support, but the software and your project files kept working. Under the subscription model, stopping payment locks the work itself. That is a different relationship. The other side of the ledger: perpetual holders with an active maintenance agreement are migrated at no cost beyond the annual renewal they already pay (and whatever that renewal climbs to). Nobody is being handed a surprise invoice this summer. What changed is what happens if you ever stop paying, and that is the kind of change you only notice the year you need it.

The real price is quote-based, and the AI costs extra. ConstructConnect publishes no price for On-Screen Takeoff anywhere, including on its own pricing page, which lists OST as "contact us for pricing." Third-party listings and user reports put it roughly between $1,044 and $1,850 per user per year, before Quick Bid. The subscription comes in Standard, Advanced, and Premium tiers, none priced publicly, billed annually with no monthly option. Takeoff Boost, the AI that automates counting and measurement, is a separate subscription on top of the OST subscription, price also unpublished. When every number requires a sales call, comparison shopping is exactly what the pricing structure is discouraging. Price has been the most common user complaint for years; one estimator on Reddit put the OST plus Quick Bid setup at $5,000 to $6,000 for a single seat.

The technology is aging while the product family shrinks around it. OST remains a Windows desktop application (Windows 11 Pro or Enterprise, per its system requirements), and on Apple Silicon Macs, ConstructConnect says virtualization is the only way to run it. Reviewers describe crashes that lose hours of work and lag on sheets with several hundred items, and estimators on Reddit warn that its project databases are Microsoft Access files that do not belong on shared storage. The surrounding history does not build confidence either: PlanSwift users report perpetual licenses ended there in 2025, PlanSwift's checkout now lists $2,000 a year, Quick Bid is next in line for the subscription transition per ConstructConnect's FAQ, and estimators still bring up what happened to SmartBid after the same company acquired it.

OST is fast in trained hands, its condition libraries carry whole trades' worth of setup, and its plan overlay still earns specific praise in reviews, even with its one-overlay-at-a-time limit. If your operation runs on Digital Production Control to track field labor against the takeoff, nothing in this guide replaces that piece, and staying on subscription OST with eyes open is a defensible choice. The rest of this guide is for everyone who mostly measures, counts, and prices, and would rather not fund the new deal out of habit.

What You Lose When You Leave On-Screen Takeoff (and What Replaces It)

An OST workflow is really five or six workflows stacked together, and the right replacement depends on which ones you use.

The pattern: if your OST use is mostly measuring and counting, with pricing in Quick Bid used lightly or in a spreadsheet anyway, a focused takeoff tool replaces the daily work for a fraction of the cost. If you run the full OST plus Quick Bid stack, where quantities flow into priced line items as you measure, you need a replacement with estimating depth: STACK Pro in the cloud, or eTakeoff Dimension feeding Sage Estimating through Bridge. And if DPC production tracking is load-bearing for your company, say so out loud in the evaluation, because no alternative on this list does it.

The 8 Best On-Screen Takeoff Alternatives in 2026

These are ranked for the takeoff job specifically: how well each tool measures construction drawings, counts what needs counting, organizes quantities, and gets numbers into a bid, weighted by cost and platform. Every price was checked in July 2026 against the vendor's official pricing page where one exists; where a vendor hides pricing, we say so.

1. Easy Takeoffs

What it is. A browser-based takeoff tool built to do one job well: measure construction drawings and turn the measurements into material quantities. Upload a PDF, set the scale (auto detection reads it from the drawing, and you confirm it before it applies), and measure with linear, polyline, polygon, rectangle, circle, freehand, count, and angle tools.

Price. $39 per month or $399 per year. 14-day free trial, no credit card. That is less than any other full takeoff tool in this guide, and several hundred dollars a year less than the low end of what OST users report paying.

Platform. Runs in any browser on Mac, Windows, ChromeOS, Linux, and iPad with Apple Pencil. Nothing to install, no license manager, projects auto-save to the cloud.

Takeoff tools. All eight measurement tools, automatic scale detection with an AI fallback for scanned sheets, AI page naming that labels every sheet from its title block, snap to drawing geometry, multiple scales per document, color-coded measurement groups with live totals across square feet, linear feet, count, perimeter, volume, and wall area, more than 40 material templates plus a community library, a custom formula editor with waste factors, and plan revision comparison. Counting is where OST users should look hardest: draw a box around one symbol and symbol search sweeps the entire plan set, streams the matches in with thumbnails, and lets you uncheck anything wrong before the checked matches become counts in one step. Text search covers every sheet the same way, scanned pages included. Markup is in the box too (callouts, revision clouds, arrows, shapes, text, stamps, and saveable custom tools), and everything exports to annotated PDF and CSV with material totals.

Best for. Estimators who used On-Screen Takeoff to measure and count, want their numbers on whatever device they own (including a Mac), and would rather keep four figures a year than fund the subscription migration.

The honest take. Easy Takeoffs is what we make, so weigh that. We built it because the takeoff market split into enterprise platforms priced for departments and legacy Windows desktop tools that never modernized, and OST users are now caught between the two. The counting comparison is the sharp one: OST's Auto Count stops the moment a subscription lapses, and its AI upgrade is a separate add-on with no published price, while the symbol search above is included at $399 a year and every match is yours to check before it counts. What we do not have is Quick Bid. Our material templates turn measurements into quantities for drywall, painting, flooring, and general contractor work, and the CSV export feeds the spreadsheet most shops price in, but built-in estimating with assemblies is on the roadmap, not in the software today. If that is your dealbreaker, look at STACK Pro or the eTakeoff-plus-Sage pairing below. We also do not track field production the way DPC does. See every feature, or start the free trial and run a bid through it this week.

2. eTakeoff Dimension

What it is. The closest like-for-like replacement on this list: an established Windows desktop takeoff tool used by commercial estimating departments, from an independent company that publishes its prices. For a Sage Estimating shop, its Bridge product drops measurements straight into the estimate, which makes it the natural OST-plus-Quick-Bid successor in that ecosystem.

Price. Advanced at $795 per user per year, Premier at $1,495 per user per year, published right on its pricing page. The Togal.AI add-on for AI takeoff is another $1,800 per user per year on top of either tier. A 15-day trial is available, and there is a limited viewer version.

Platform. Windows desktop only. Its own support pages say Mac use means Parallels or VMware.

Takeoff tools. Measurement with layers and bid codes, drawing-comparison overlays, Excel integration, and multi-user database setups. The OST-style muscle sits in Premier: Pattern Search auto-count, assemblies (eTakeoff calls them extensions), and the patented SnapAI cursor-snapping that reads a vector PDF's own geometry to lock onto points and lines.

Best for. Commercial estimating departments that want to stay on a desktop tool, keep an assemblies-driven workflow, and especially anyone already estimating in Sage.

The honest take. eTakeoff is what OST users usually imagine when they say "the same thing, but not ConstructConnect," and the published pricing is a mark of respect after years of quote-only sales calls. Three trade-offs, though: it sits at 3.9 on Capterra with a steep learning curve as the recurring complaint, the interface is the same vintage as OST's, and the parts that match OST's strengths need Premier at $1,495, with AI pushing past $3,000 per user per year once the Togal add-on is bolted on. You escape the vendor, not the desktop-era workflow.

3. STACK

What it is. The browser-based platform that most directly rebuilds the OST-plus-Quick-Bid combination in one place: measurement, assemblies, and estimating, all cloud-hosted. It has been cloud-first since before most of its rivals existed, which shows in how finished it feels.

Price. Premium at $249 per user per month and Pro at $299 per user per month, both billed annually (about $2,988 and $3,588 a year). Pro carries the integrated estimating. The AI takeoff features are paid add-ons on top. A limited free account and a 7-day Pro trial exist.

Platform. Browser-based, so it runs on Mac and Windows alike.

Takeoff tools. Every measurement type, plus assemblies that attach materials and labor to each condition, shared cost libraries, and proposal generation on Pro. AI symbol detection is a paid add-on. The structure (a bid, holding conditions, holding quantities) is built for a team splitting one estimate between several estimators.

Best for. Multi-estimator shops that ran the full OST and Quick Bid stack and want takeoff, assemblies, and pricing in one modern cloud platform, with the budget to match.

The honest take. STACK is the strongest answer to "give me everything OST and Quick Bid did, in a browser," and our Easy Takeoffs vs STACK comparison covers the differences in detail. It is also the price of a used truck for a three-person team: roughly $9,000 to $10,800 a year before AI add-ons, and estimators on Reddit sizing it up from OST regularly balk at exactly that math. If you use the whole platform, it earns the money. If you mostly measure and count, you are buying a department's tool for one seat's job, and our best STACK alternatives guide is written for exactly that situation.

4. Bluebeam Revu (Complete)

What it is. The construction industry's standard PDF platform, with takeoff tools in its upper tiers. In estimator forums it is the default first suggestion whenever OST comes up, because most offices already have some Revu seats.

Price. Basics at $260, Core at $330, Complete at $440, and Max at $590 per user per year. The takeoff features that matter, Quantity Link to Excel and Dynamic Fill, live in Complete and Max, so the comparison price is $440.

Platform. Revu desktop is Windows-only. The browser-based Bluebeam Cloud runs on Mac and iPad but lacks the desktop takeoff depth.

Takeoff tools. Length, area, count, and volume measurement, with Quantity Link pushing totals to Excel and Dynamic Fill flooding an enclosed region into an area, both on desktop Complete, all wrapped inside a much larger markup and collaboration platform.

Best for. Windows estimators who spend as much time marking up and sharing drawings as measuring them, and want one tool for both.

The honest take. At $440 a year, Complete does takeoffs plus everything a PDF platform does, which makes it the value pick for markup-heavy shops, and our Easy Takeoffs vs Bluebeam comparison puts the two side by side. But takeoff is a feature in Bluebeam, not the point of it: there is no condition-library workflow, and quantities organize through Excel rather than a purpose-built structure. Bluebeam also carries its own version of the story you are escaping, told in full in our best Bluebeam alternatives guide: it stopped selling perpetual licenses in 2023, and Revu 20, the last perpetual version, reaches end of support on July 31, 2026 and end of life that December.

5. Kreo

What it is. The cheapest route on this list to AI that measures and counts for you. Kreo runs in the browser and pairs manual takeoff with AI auto-measure and auto-count.

Price. Lite at $35, Plus at $70, and Pro at $175 per user per month, billed annually. The catch: AI Auto Measure and Auto Count live only on Pro, so the working price of AI takeoff is $175 per user per month, about $2,100 a year.

Platform. Browser-based on Windows, Mac, and Linux.

Takeoff tools. Manual measurement across the usual tools, with AI detection of areas and symbols layered on and estimating on top. Its Auto Count works the way OST users expect: pick a symbol, let it sweep the set, then review what it flagged.

Best for. Estimators who want AI to do the first pass on high volumes of drawings without paying STACK or Togal prices.

The honest take. Kreo is the value play in AI takeoff, and our guide to the best AI takeoff software puts its AI head to head with Togal and STACK. For repetitive fit-out work the auto-measure saves hours, but it is a smaller company than anything else here and less polished for it, and like every AI takeoff tool in 2026 it hands you a first pass to check, not a finished takeoff.

6. Togal.AI

What it is. The most established AI-first takeoff tool, built around one-click detection of rooms, areas, and features on architectural plans. It is also, in a twist, the AI engine eTakeoff resells as its own add-on.

Price. Growth at $299 per user per month, billed yearly (about $3,588 a year). The Business tier for teams of four or more is quote-based. The cheaper Essential tier no longer appears on its pricing page as of July 2026.

Platform. Cloud web app. Accepts PDF, JPEG, PNG, and TIFF.

Takeoff tools. One-click AI detection of rooms, areas, and counts, with manual tools to fix what it misses. It is fastest on clean vector floor plans, which is where its headline accuracy claims come from; hand it a messy scan and more of the work comes back to you.

Best for. High-volume estimators on straightforward plan sets who want to trade subscription cost for speed.

The honest take. Togal's detection is the most polished in the category, and estimators leaving legacy desktop tools regularly praise its cloud workflow. It is also tied with STACK Pro for the priciest per-seat number here, and on messy scanned drawings the AI advantage shrinks fast. If price was already your top complaint in OST, $3,588 a year deserves a hard look at how much of your plan volume the AI will actually handle.

7. Square Takeoff

What it is. The simple, iPad-friendly option, popular with remodelers and residential contractors who work as much in the field as at a desk.

Price. $249 per month, $599 per quarter, or $1,699 per year, with unlimited jobs and storage. 14-day free trial.

Platform. Browser-based on Mac, Windows, and iPad.

Takeoff tools. Area, linear, and count measurement with estimating basics and a parts catalog. Its material-template depth is lighter than STACK's or Easy Takeoffs'.

Best for. Residential and remodel contractors who do field work on an iPad and want one simple tool.

The honest take. Square Takeoff fits the residential end of OST's audience: simpler than the platforms, polished on a tablet. But at $1,699 a year it costs about what OST users report paying now, for a tool that does less, and a simpler tool that is not also cheaper is a hard sell.

8. PlanSwift

What it is. ConstructConnect's other Windows desktop takeoff tool, aimed more at residential and light commercial work, with drag-and-drop assemblies and trade plug-ins. It is the stay-in-the-family option, listed here because OST users will hear it suggested.

Price. PlanSwift's checkout page lists the Professional Subscription at $2,000 per year as of July 2026; users reported $1,749 at the 2025 transition, when perpetual licenses ended. Trade plug-ins cost extra, and the Takeoff Boost AI add-on has no published price.

Platform. Windows desktop only. ConstructConnect's guidance for Mac users is a Windows virtual machine.

Takeoff tools. Point-and-click takeoff with drag-and-drop assemblies that turn a measurement into a priced line item. The interface has changed little in a decade, and reviewers report strain on large plan sets.

Best for. Nobody leaving On-Screen Takeoff over the licensing change, frankly. It is the same company, the same licensing direction, and the same Windows-only desktop model.

The honest take. Moving from OST to PlanSwift is switching seats on the same boat. PlanSwift went through the identical perpetual-to-subscription shift a year earlier, its price has already climbed since, and its users are writing the same forum posts OST users are starting to write now. We wrote a full guide to the best PlanSwift alternatives for exactly that audience, and our Easy Takeoffs vs PlanSwift comparison has the feature-by-feature breakdown.

Popular "On-Screen Takeoff Alternatives" That Are Not Takeoff Tools

Search this topic and the software directories will hand you lists dominated by tools that cannot do a quantity takeoff at all. As of July 2026, one major directory lists OST's price as $15 a month, off by roughly a factor of ten, and another still advertises a PlanSwift lifetime license that stopped existing years ago. Treat those pages accordingly. Here are the names you will see most, and what they actually are.

Buildertrend belongs on the same list: good residential project management, not a takeoff tool. Two more names deserve a flag from inside the ConstructConnect family itself: Quick Bid and QuoteSoft are estimating tools that pair with a takeoff tool, not replacements for one, and per ConstructConnect's own FAQ, Quick Bid is planned to follow OST into subscription-only licensing. If you already run Procore for project management, our Easy Takeoffs vs Procore comparison covers pairing a focused takeoff tool with it.

How to Switch Off On-Screen Takeoff Without Losing Work

The practical fear is losing years of takeoff data. The answer: takeoff tools do not import each other's measurements, in either direction, so that limit is the same whichever one you pick. Your OST projects stay readable in OST for as long as your license or subscription runs. The switch affects only new work, which makes it a rebuild of your setup rather than a data migration, and the rebuild is smaller than it sounds.

One OST-specific step comes first, though, and it has a deadline. Because a migrated company that later lapses ends up with read-only projects, export or print reports for your completed bids while everything still works: the takeoff summaries and worksheet tabs export to Excel and CSV. Do it before your company is transitioned, not after, and your history stays usable no matter what you decide later.

The rebuild itself has three parts. First, capture your condition library: list the conditions you actually used on your last ten bids. Most estimators find it is five to fifteen, not the hundreds in the database. Second, recreate those as groups and templates in the new tool; in Easy Takeoffs the built-in and community templates usually cover most of the list before you write anything custom. Third, run the parallel job and compare totals. If you have never measured in a browser tool, our guide to measuring a PDF walks through the whole flow, from setting the scale to exporting quantities.

How to Choose the Right On-Screen Takeoff Alternative

Start with one question: how much of the OST plus Quick Bid stack did you actually use? Everything else follows.

If you mainly measured and counted, and pricing happened in a spreadsheet or lightly in Quick Bid, pick a focused takeoff tool and keep the difference. Easy Takeoffs is the cheapest and runs on everything; Square Takeoff is the iPad-centric residential option. If you ran the full estimating stack with condition libraries and live pricing, you need a replacement that estimates, not just measures: STACK Pro in the cloud, or eTakeoff Premier feeding Sage Estimating through Bridge. If you want AI to do the first pass, Kreo is the value entry and Togal the premium option, and both charge for it. If you are staying on a Windows desktop tool no matter what, eTakeoff is the independent choice and Bluebeam Complete the markup-heavy one. A newer cloud tool called zzTakeoff also comes up often in estimator forums as a landing spot; it is young, but worth a look if you are surveying the whole field.

Then apply two filters. Platform: if anyone on your team works on a Mac, the Windows desktop options are out, because on Apple Silicon even ConstructConnect says virtualization is the only path, and a Parallels-plus-Windows setup adds a few hundred dollars a year to run software you are trying to stop overpaying for. Our best takeoff software for Mac guide goes deep there. Full-year cost: compare complete annual numbers, including AI add-ons, estimating modules, and per-seat math, not headline tiers. Our cheapest construction takeoff software guide does that math across the whole category.

Frequently Asked Questions

Is On-Screen Takeoff still supported in 2026?

Yes, for subscribers, and ConstructConnect is still releasing updates. But the support picture narrowed fast for everyone else. Old versions were retired in waves: 3.95 and older in August 2023, 3.96 and most 3.98 releases in August 2025, and all 3.97 builds on October 24, 2025, with ConstructConnect stating it provides no support for retired versions, not even activation assistance. Perpetual license holders began being migrated to subscriptions in June 2026, and the legacy licensing system is deprecated by the end of 2026.

How much does On-Screen Takeoff cost?

ConstructConnect does not publish a price; its pricing page says to contact sales. Third-party listings and user reports put On-Screen Takeoff roughly between $1,044 and $1,850 per user per year, and the subscription comes in Standard, Advanced, and Premium tiers, none with published prices. Quick Bid estimating is separate, with estimators describing the combined setup at $5,000 to $6,000 for a single seat, and the Takeoff Boost AI requires its own subscription with no published price either.

What happens to my On-Screen Takeoff perpetual license?

Under ConstructConnect's published transition plan, companies are being migrated to subscription licensing starting June 2026, and once a company is transitioned, licenses for the old versions are disabled. If you hold an active maintenance agreement, you receive subscription access at no additional cost beyond your usual annual renewal. The change shows up if you ever stop renewing: ConstructConnect states that the subscription-enabled features (Auto Takeoff, Auto Count, and the rest of the automation and sharing tools) shut off, and your projects open in read-only mode. Exporting reports for completed bids before the transition is the sensible precaution.

Does On-Screen Takeoff run on a Mac?

No. It is a Windows desktop application, and ConstructConnect's own system requirements say that on Apple Silicon Macs the only option is running Windows in virtualization software, which it does not provide support for. If your shop has Macs, a browser-based tool is the practical path: Easy Takeoffs runs in Safari or Chrome on the Mac you already own, and our Mac platform guide covers the details.

Can I export my On-Screen Takeoff data to another program?

Quantities, yes; measurements, no. OST exports takeoff summaries and worksheet data to Excel and CSV, so your numbers and reports travel. The measured drawings themselves do not, and that is true of every takeoff product, not a quirk of any one competitor. The practical approach is to export reports for completed bids while your access is active, then rebuild your common conditions as templates in whichever tool you choose.

Is PlanSwift a good replacement for On-Screen Takeoff?

Only if your reason for leaving has nothing to do with ConstructConnect, because PlanSwift is owned by the same company and went through the same perpetual-to-subscription change a year earlier. It is Windows-only, its checkout page lists $2,000 a year as of July 2026, its trade plug-ins and AI add-on cost extra, and its users are searching for alternatives for the same reasons you are. Our best PlanSwift alternatives guide covers that side of the family.

What replaces the On-Screen Takeoff and Quick Bid combination?

Three realistic paths. STACK Pro ($299 per user per month, billed annually) puts takeoff and estimating in one cloud platform, the closest single-product equivalent. eTakeoff Dimension Premier ($1,495 per user per year) plus its Bridge integration recreates the pairing for Sage Estimating shops. Or split the jobs: a focused takeoff tool like Easy Takeoffs ($399 per year) for measuring and counting, with material templates and CSV export feeding the spreadsheet or estimating system you already price in. Which is right depends on how deeply you used Quick Bid, so answer that before you pay for a full estimating platform you may not need.

The Bottom Line for On-Screen Takeoff Users

On-Screen Takeoff earned its place. It is a capable tool with strong ratings, and for twenty-plus years buying it meant owning it. That era ended by published policy: subscription-only sales from version 4.0.0.805, perpetual migrations underway since June 2026, and the old licensing system gone by the end of the year. Renewing out of habit is a decision too, and it deserves the same scrutiny as switching.

The decision itself is simpler than the directory listicles make it look. If you ran the full estimating stack, move to a platform that does that job: STACK Pro, or eTakeoff with Sage. If DPC production tracking runs your field operation, staying is legitimate. And if your OST hours were mostly measuring and counting, stop paying quote-gated prices for that job entirely.

That last group is who we built Easy Takeoffs for. It does the measuring and the counting, runs in the browser you already have on Mac, Windows, or iPad, and costs $399 a year. The 14-day free trial needs no credit card, so run a bid you already did in OST this week and let the quantities make the argument. For side-by-side breakdowns, the comparison hub covers Bluebeam, PlanSwift, STACK, and Procore.
