What kinds of construction estimating software are there?
Construction estimating software, also called construction estimator software, is not one product, and the best construction estimating software depends on which job you need done. Most contractors who say they need it need one of four tools, and some need a person instead.
- Takeoff software measures quantities from digital plans: areas, lengths, counts and volumes. Examples: PlanSwift, On-Screen Takeoff, STACK, Bluebeam Revu, Kreo, Square Takeoff.
- Estimating software and cost data turns quantities into a priced estimate with labor, material, equipment and markup. Examples: Procore Estimating, STACK estimates, spreadsheets, and cost databases such as RSMeans.
- Bid management platforms send and receive invitations to bid and compare bids. Examples: BuildingConnected and Bid Board Pro from Autodesk.
- AI takeoff detects rooms, areas and symbols automatically for a first pass. Examples: Togal.AI, PlanSwift Core’s Auto Takeoff and ConstructConnect Takeoff Professional.
None of these reads a specification or decides what to exclude. That judgment still comes from an estimator, in-house or outsourced.
Construction takeoff software: what it costs
Takeoff software is where most contractors start, whether that is On-Screen Takeoff, Bluebeam takeoff tools or a cloud product. Prices below are list prices from each vendor’s own page, checked November 7, 2026.
| Tool | Published starting price | Platform | Notes |
|---|---|---|---|
| STACK Takeoff & Estimate | Free version; paid as low as $299 per user per month | Web | Takeoff plus estimates and proposals |
| Bluebeam Revu | Basics $260, Core $330, Complete $440 per user per year | Windows desktop, web, mobile | PDF markup and review with measurement |
| PlanSwift | Essential $2,000, Core $3,000 per seat per year | Windows desktop | Trade assemblies; Core adds Auto Takeoff |
| ConstructConnect Takeoff | Starter $1,200 per year; Professional $2,450 per seat per year | Cloud | Annual contract; Professional adds Auto Takeoff |
| On-Screen Takeoff | Not published; request a trial | Desktop | ConstructConnect product moving to subscription logins |
| Togal.AI | Growth $299 per user per month, billed yearly | Web | AI area and symbol detection |
| Kreo | Essential $100, Pro $175 per user per month, billed annually | Web | 7-day trial |
| Square Takeoff | $249 per month, $599 per quarter or $1,699 per year | Browser, Mac or PC | All features in every plan |
Software price is only the license. Add training, setup of assemblies and the estimator hours to run it. See PlanSwift alternatives for more detail on takeoff tools.
RSMeans and Procore Estimating: cost data and estimating platforms
RSMeans cost data from Gordian is a widely used published construction cost database. RSMeans Data Online lists three plans:
- Core: from $408 per year. Material, labor and equipment costs.
- Complete: from $1,049 per year. More data depth and historical cost analysis.
- Complete Plus: from $5,973 per year. Adds predictive cost forecasting up to three years ahead.
RSMeans includes unit costs, assemblies and square foot models, localized to more than 970 locations in North America with quarterly location factors. It gives you prices, not quantities. You still need a takeoff, and published costs should be checked against your own crews and suppliers.
Procore Estimating combines takeoff and estimating inside Procore’s platform. Procore says takeoff data flows into the estimate, with an editable library of parts and assemblies. Procore does not publish dollar prices. Its pricing page describes annual contracts with unlimited users. It fits contractors already running projects in Procore.
BuildingConnected and bid management software
Bid management software moves invitations and bids, not quantities. It does not estimate anything.
BuildingConnected is Autodesk’s bid network. BuildingConnected Pro is aimed at general contractors and owners to send invitations and compare bids. Bid Board Pro is for subcontractors. It pulls BuildingConnected invitations into one board, tracks deadlines and reports win rates. TradeTapp handles subcontractor qualification. Autodesk sells these through sales, alone or in its Preconstruction bundle with ProEst, Forma Takeoff and Forma Estimate. It does not publish prices.
Procore and ConstructConnect also sell bid management tools. If your problem is tracking invitations, a bid board helps. If your problem is pricing the invitations you already have, it does not.
Can AI takeoff replace an estimator?
Not yet. AI takeoff speeds up the first pass on repetitive items such as room areas, doors and fixtures. It does not read specifications, catch scope that sits in Division 01, or decide what to exclude.
The limits are measurable. In October 2026, Togal.AI released a benchmark called Construction’s Last Exam: 33 real-world construction tasks such as reading plans and measuring spaces. Leading general-purpose AI models, including ChatGPT and Claude, scored between 2% and 34% accuracy, according to Togal.AI. The results come from a vendor that sells its own AI takeoff and have not been independently validated. They tested general-purpose chat models, not dedicated takeoff tools.
The practical rule: treat every AI quantity as a draft. Check it against the plans before it goes into a price.
Short on time? Bidmere can do this for you. Trade estimates from $195, ready in 48 hours. See construction estimating services or get a fixed quote.
Is there free construction estimating software?
Yes, with limits. STACK lists a free version of its takeoff and estimating product, which makes it the usual starting point for anyone looking for construction takeoff software free of charge. A free construction estimator app on a phone can total a few line items, but it will not measure a PDF plan set. Most other tools offer trials: PlanSwift and Square Takeoff list 14 days, and Kreo lists 7 days.
The other free option is a spreadsheet. A construction estimating spreadsheet in Excel or Google Sheets handles pricing well. Pair it with a takeoff template for small jobs. Bidmere’s free construction templates include an estimate template and a material takeoff template. Spreadsheets break down on large plan sets, multi-trade jobs and teams that share estimates.
For a quick check before a full estimate, try the free insulation estimator or roofing estimator.
When does estimating software make sense?
Estimating software for contractors wins when you have steady volume and someone whose job is to run it. For construction estimating software for small business use, the license is rarely the problem; the hours to run it are. Buy software when most of these are true:
- You bid every week, all year
- You have an estimator, or an owner, with hours set aside to measure
- You bid the same trade and building types, so assemblies get reused
- You want your own library of historical quantities and costs
- Several people need to share and review estimates
At that volume, a license is cheap per bid. The real cost is the person. The US Bureau of Labor Statistics reports a median annual wage of $78,740 for cost estimators in May 2025, before benefits and overhead.
When does an estimating service beat software?
A service wins when the bottleneck is hours, not tools. Outsource when most of these are true:
- Bids arrive in bursts, and you pass on work in busy weeks
- Nobody in the company has time to measure
- You are bidding a trade or project type you rarely price
- You need a second set of quantities to check your own number
- You bid a few times a month, so a license and training sit idle
Bidmere returns measured trade takeoffs and cost estimates priced at your rates. Takeoffs are priced from $149. Single-trade estimates are priced from $195 and take 48 hours. Multi-trade estimates are from $1,150. Delivery is an Excel estimate with live formulas, color-coded marked-up PDF plans, and a written list of assumptions, exclusions and open questions. Every job gets a fixed quote within 2 business hours, and you pay only after you accept.
The hybrid: software in-house, overflow to a service
Many contractors use both. The in-house estimator runs software on core bids, and overflow, unfamiliar trades or tight deadlines go out.
How the hybrid usually works:
- Keep your estimate template and rates as the standard.
- Send overflow plans with your template and rates.
- Get quantities and pricing back in your format.
- Your estimator reviews, adjusts and sets the final number.
For steady overflow, a monthly plan is simpler than ordering job by job.
Software or service: a quick way to decide
| Your situation | Likely fit |
|---|---|
| Weekly bids, dedicated estimator, repeat building types | Takeoff and estimating software |
| A few bids a month, no estimator | Estimating service, job by job |
| Steady weekly bids, estimator overloaded | Software plus a monthly estimating plan |
| New trade or unfamiliar project type | Service for the first bids, then decide |
| Need to track and answer many invitations | Bid management software |
| Early budget with little design | Cost data such as RSMeans, or a budget estimate service |
Whatever you choose, the estimate is only as good as the person who reads the specs. Tools speed up measuring. They do not replace judgment.
Frequently asked questions
Which construction estimating software fits a small business?
It depends on volume and trade. For occasional bids, a spreadsheet plus STACK’s free version may be enough. For weekly bids, a paid takeoff tool such as Bluebeam, Kreo, Square Takeoff or PlanSwift fits, with published prices from $260 a year. If nobody has time to run software, an estimating service is the alternative.
How much does construction estimating software cost?
Published prices checked November 7, 2026 range from free (STACK’s free version) to $260 per user per year (Bluebeam Basics), $1,200 to $3,000 per seat per year (ConstructConnect Takeoff and PlanSwift), and $299 per user per month (Togal.AI Growth, STACK paid). Add training and estimator time to the license.
What is RSMeans cost data?
RSMeans is a construction cost database from Gordian with unit costs, assemblies and square foot models, localized to more than 970 North American locations with quarterly location factors. RSMeans Data Online plans start at $408 per year for Core. It provides prices, not quantities, so you still need a takeoff.
Is BuildingConnected estimating software?
No. BuildingConnected is Autodesk’s bid management network. General contractors use BuildingConnected Pro to send invitations and compare bids, and subcontractors use Bid Board Pro to manage invitations. It does not measure plans or price work. Autodesk’s estimating and takeoff products are sold separately or in its Preconstruction bundle.
What is On-Screen Takeoff?
On-Screen Takeoff is a desktop takeoff program from ConstructConnect, the company that also owns PlanSwift. ConstructConnect does not publish its price and offers a free trial on request. ConstructConnect also sells a newer cloud product, ConstructConnect Takeoff, with published plans from $1,200 per year.
How accurate is AI takeoff?
Dedicated AI takeoff tools speed up areas and counts, but every result needs checking. In Togal.AI’s October 2026 Construction’s Last Exam benchmark, general-purpose models including ChatGPT and Claude scored 2% to 34% on 33 construction tasks. Togal.AI created the benchmark, and the results have not been independently validated.
Is it cheaper to outsource estimating than buy software?
At low or uneven volume, usually yes, because a license and the hours to run it sit idle between bids. At high, steady volume with an estimator on staff, software usually costs less per bid. Bidmere single-trade estimates are priced from $195, so compare that against your license plus estimator time per bid.
Can I use Bidmere with my own estimating software?
Yes. Send your estimate template, labor rates and material pricing with the plans. Quantities and pricing come back organized by your scope items so your estimator can bring them into your own system, review them and set the final number. Delivery is an Excel estimate with live formulas, color-coded marked-up PDF plans, and a written list of assumptions, exclusions and open questions.
