I evaluated the best free construction estimating software and narrowed the list down to eight standout tools: Autodesk Forma, UDA ConstructionOnline, Handoff, Houzz Pro, Knowify, Methvin, Procore, and STACK Takeoff & Estimate.
If you’re already looking for construction estimating software, chances are you’ve outgrown spreadsheets, manual takeoffs, or disconnected tools. The bigger question now is whether you need to pay for a platform right away.
For contractors, builders, and estimating teams, free software can be a practical way to test the workflow before committing to a budget. But “free” varies widely. Some tools offer ongoing free plans, while others only provide limited trials or restricted access to estimating, takeoff, bidding, and proposal features.
That’s why I focused this guide on what you can actually use before paying. I compared the top free construction estimating tools on G2 based on their no-cost access, estimating and takeoff capabilities, feature limits, and upgrade paths. I’ll show you what each tool includes for free, where the restrictions start to matter, which teams each option fits best, and when paying for more becomes worthwhile.
Autodesk Forma: Best for large teams needing connected project data
A strong fit for larger construction teams that want project data, drawings, models, and collaboration centralized in one cloud platform.
UDA ConstructionOnline: Best for small builders needing estimating and support
Built for growing residential and specialty contractors that want estimating, takeoff, job costing, and project management backed by hands-on support.
Handoff: Best for residential contractors needing fast AI estimates
Best suited to remodelers, home builders, and small contractors that want to turn project details, photos, or plans into estimates and proposals quickly.
Houzz Pro: Best for design-focused residential remodelers
A practical option for remodelers and designers that want estimates and invoicing alongside visual tools such as 3D floor planning.
Knowify: Best for trade contractors using QuickBooks
A strong fit for specialty contractors that want estimates, job costing, invoicing, and expenses connected closely with QuickBooks.
Methvin: Best for civil estimators needing detailed cost breakdowns
Well-suited to civil and infrastructure teams that want first-principles estimating, takeoffs, and structured subcontractor bid comparisons.
Procore: Best for large contractors managing projects at scale
Built for general contractors that want estimating connected with budgets, RFIs, submittals, contracts, and broader project management workflows.
STACK Takeoff & Estimate: Best for high-volume digital takeoffs
A strong choice for subcontractors and estimators that want fast cloud-based measurements, counts, and material takeoffs directly from construction plans.
I found that free plans can vary significantly from one tool to another. This comparison highlights the key differences at a glance.

Construction estimating software is becoming a bigger part of how contractors plan and price projects. The global market is expected to grow from $1.7 billion in 2026 to reach $3.8 billion by 2033, growing at a CAGR of 12.3%.
That growth reflects the increasing role estimating software plays in replacing manual calculations and spreadsheets with more structured takeoffs, cost estimates, and bids. For contractors and estimating teams that aren’t ready to commit to a paid platform, free plans and trials offer a practical way to test these workflows on real projects before deciding whether an upgrade is worth it.
I started with the top free products in G2’s construction estimating software category and focused on tools that offer a free plan, freemium model, or free trial. For each product, I reviewed official pricing pages, plan details, and product documentation to verify what the free offering includes and where the limitations begin.
I evaluated these tools from a contractor and estimating team perspective, focusing on factors such as takeoff capabilities, cost estimating, bid and proposal creation, project limits, collaboration features, integrations, ease of use, and upgrade restrictions. I also reviewed G2 feedback to understand how these tools perform in real construction workflows and whether the free offering provides enough value to test the software before paying.
This analysis is based on publicly available product information and G2 reviews available in 2026. Some reviews may have been edited for clarity.
When evaluating free construction estimating software, I focused on whether the free offering gives contractors and estimating teams enough access to understand how the product would fit into their workflow before paying.
To be included on this list, a tool must:
*This data was pulled from G2 in 2026. Some reviews may have been edited for clarity.
Autodesk Forma struck me as the heavyweight of this group. It holds the largest market presence on G2 in the category, and I could see why its base skews big: 46% of reviewers sit at mid-market firms and 28% at enterprises. This isn't a lightweight standalone estimator; it's a cloud platform built to hold an entire project team in one place.
Two strengths stood out to me across the G2 reviews. The first is collaboration. Users most often mention how easily they share models and coordinate in real time, and I'd read its 90% score for ease of doing business with, its strongest satisfaction metric, as the backing for that. The second is centralization; I kept seeing teams describe it as a single hub for documents and drawings, which lines up with its 81% rating for integrations, the highest-rated feature on its profile. Worth knowing before you start: there's no free-forever plan, only a 30-day trial.
As soon as the 30-day trial ends, you will need Forma for live, ongoing projects. A standalone Forma Site Design plan starts at around $59 per month, and it's also bundled into the Autodesk AEC Collection at $307 per month if you want Revit, AutoCAD, and Civil 3D alongside it. Teams already on the AEC Collection get Forma at no extra cost.
“We have been implementing Autodesk Forma as our CDE for 10 years now, with more than 600 projects and growing. We love all the collaboration tools, the interface, and the support provided.”
- Autodesk Forma review, Juan T.
Best for: Larger, multi-disciplinary teams that need everyone working off one connected source of project data.
Not ideal for: Solo contractors or small crews who just want a quick, free, standalone takeoff or estimate without committing to a subscription.
“The biggest downside or hurdle is the initial rollout. Getting everyone on board and trained to use the platform is initially a large challenge. It's also not great integrating with other platforms. If your customer or GC is using a different platform it isn't ideal.”
- Autodesk Forma review, Verified User in Construction
While evaluating UDA ConstructionOnline, I found it to be one of the more estimating-heavy tools in this roundup, an all-in-one platform for running projects, teams, and finances. Estimating and takeoff are what jumped out at me, and G2 users agree: they describe its OnCost estimating and job costing as some of the best they've worked with, and the built-in Redline takeoff as unusually quick to pick up. That focus carries into the ratings, where digitizing quantities lands as its top-scoring feature at 87%.
Support was the second thing I kept seeing praised. ConstructionOnline earns a 98% quality-of-support score, seven points above the 91% category average, and I noticed users describing help that's a quick chat or call away, backed by real onboarding and training. Just know going in: there's no free-forever tier. I could run the full platform on a free 10-day trial, but ongoing use runs on a paid, industry-specific subscription.
Once your 10-day trial is up, you're ready to run live jobs on it. Pricing is set by trade rather than by seat: the Residential plan starts at $475/month, Specialty & Subs at $575/month, Commercial at $650/month, and Multi-Family at $950/month. Smaller shops can also start on the lighter CO Basics tier and move up as they grow.
“I would probably have to say accessibility is great because I have it on my work computer, iPads, and cell phone. No matter where I'm at, I can access the job site, so I always have the answers I need within reach. It's extremely beneficial because when I'm bouncing from job site to job site and getting calls from contractors, I can pull up answers quickly, ensuring that the job doesn't slow down. This access speeds up the work as I can immediately provide answers to the contractors, which is crucial for being successful with home building and remodeling.”
- UDA ConstructionOnline review, Bryan H.
Best for: Small and growing builders who want serious estimating power alongside a support team that actually picks up the phone.
Not ideal for: Budget-minded solo operators, or anyone who needs a genuinely free tool, since ConstructionOnline is a paid, premium platform.
“While UDA ConstructionOnline has useful project management features, I find the interface can be cumbersome and not always intuitive. Certain tasks require multiple steps to complete, which can slow down the workflow. Reporting and document management could be more streamlined, and the mobile experience is not always as efficient as the desktop version. Better integration with accounting software and more customizable dashboards would also improve the overall user experience.”
- UDA ConstructionOnline review, Daniel M.
If estimating is the part of the job you dread, Handoff felt built for exactly that when I dug into it. It's an AI estimating app for residential remodelers, home builders, and handymen; you describe the job or upload photos and plans, and it hands back a full estimate and proposal. Speed is what G2 reviewers rave about most, and I understand why: many describe cutting an estimate from a full day to around 30 minutes and getting bids out the same day as the walkthrough. Proposal generation is also its top-rated feature, at 90%.
The second thing that won me over was how little tech skill it asks for. Reviewers who don't consider themselves computer people still call it clean and quick to learn, which I'd tie to its 92% ease-of-use score and near-perfect 98% for ease of doing business with. One note: Handoff is app-first and paid, with no free-forever version, just a 7-day trial that doesn't ask for a card.
When the 7-day trial runs out and you want to keep sending estimates and proposals. Handoff runs on paid subscriptions starting at about $119/month, with a higher tier reaching roughly $719/month for more features and added team seats.
“The system is built around estimates, SOWs, and general chat related to the construction industry. I like how it looks for real-world pricing through Home Depot and allows users to put in their own variables, like markups or taxes. The estimates themselves are only as good as your description of the job, so if you're on point with your description, SOW, and plans, it's within the 90th percentile on being correct normally.”
- Handoff review, Jeff R.
Best for: Solo and small residential contractors who want polished estimates and proposals out the door fast, without hiring admin help.
Not ideal for: Larger or commercial builders who need deep integrations and airtight, no-review pricing straight out of the box.
“Sometimes it is slower than I would like. Like any AI, it does occasionally hallucinate and make mistakes. It requires more cautious proof reading of the final estimates than I would like, but the team has improved it since I've been using it. I do continue to see steady improvements in this regard.”
- Handoff review, Ryan M.

Houzz Pro comes from Houzz, the home-design marketplace, and it's aimed at the residential end of construction, remodelers, designers, and small builders. The strength reviewers raise most is the money side: I kept seeing them build an estimate, get it approved, and turn it straight into an invoice the client pays online, with no bouncing between a word processor and a spreadsheet. That smooth flow lines up with its 86% ease-of-use score, the highest of its satisfaction ratings.
The second strength that stood out to me is how visual it is. Reviewers lean on the 3D floor plans to help homeowners picture the finished space and to look polished doing it, a real edge when selling a remodel. Both strengths sit inside the free plan, which covers the 3D floor planner, estimates, and invoicing at no cost, so you can put the core workflow to the test before ever paying.
When you need more than those core three tools. The free plan covers 3D floor plans, estimates, and invoicing, but the moment you want takeoffs, selections, mood boards, CRM, or project scheduling, you'll step up to a paid tier. The Design plan starts at $99/month, Pro at $199/month, and Teams at $399/month, each with a 30-day free trial.
“As an end user, it is very straightforward and easy to access all the information and documentation relating to a project. The customer service has been great and the onboarding training was very helpful. The AI estimating tool is helpful to create estimates and greatly reduces the amount of time spent. I really appreciate how easy it is to send an invoice and tie it directly to an approved estimate or change order. The customer dashboard has been a hit with clients and facilitates communication and decision-making when used effectively.”
- Houzz Pro review, Troy L.
Best for: Residential designers, remodelers, and small builders who sell visually and want estimating, invoicing, and 3D design together in one place.
Not ideal for: Commercial or heavy-civil contractors, or solo pros who need the full feature set without stepping up to a paid plan.
“The cost is a big issue for me. It also sometimes has glitches. The syncing capability with QuickBooks isn’t always the greatest, and it can be inconsistent at times. Overall, I just wish I didn’t have to buy a second software program to do what QuickBooks already does.”
- Houzz Pro review, Jennifer K.
Knowify is a job-management platform for trade contractors, electricians, plumbers, HVAC crews, remodelers, and it's really built around the numbers. The strength I saw come up most in that vein is job costing: reviewers use it to watch budgeted costs against actuals in real time, so they can read a job's profitability while it's still running rather than after it's closed. Its cost tooling rates well too, with access to cost databases scoring 87% on G2, above the 85% category average.
What really sets Knowify apart is its QuickBooks connection; the vendor calls it the strongest QuickBooks sync in construction, and G2 reviewers repeatedly single out how cleanly estimates, invoices, and expenses flow across without double entry. That low-admin bookkeeping shows up in its 91% ease-of-admin score. One thing to note upfront: there's no free-forever plan here, just a 14-day free trial to test it first.
When the 14-day trial ends, you're ready to run live jobs on it. Knowify's Core plan starts at $99/month for a single user, the Advanced plan runs $329/month for teams that need more, and larger operations get a custom Enterprise quote.
“User-friendly overall, and the implementation process was fairly quick. The support team is very responsive. Integration with Zapier, and more recently, the MCP connectors to work with Claude, is very convenient for setting up automations or querying complex data from Knowify without much hassle. I also appreciate the frequent updates to both existing and new features. Pricing is decent compared with other software. Being a cloud-based SaaS makes it easy to work from pretty much anywhere with an internet connection.”
- Knowify review, Vic T.
Best for: Trade and specialty contractors who run their books in QuickBooks and want real-time visibility into job profitability.
Not ideal for: Teams that need deep custom reporting, or anyone after a permanently free tool, since Knowify is subscription-only.
“The form and format of material allocations for service jobs needs to allow the user to expand/resize the windows. As-is, the item column is way too narrow to show all the entered text. It's OK for entering, but if you want to look something up you can't read it in the very limited space. If you click on an item so you can read it, the job window closes right after, so you have to reopen the job window to continue.”
- Knowify review, Verified User in Construction
Methvin is a cloud estimating, takeoff, and project management platform, built mainly for civil and infrastructure work. What sets it apart, and what G2 reviewers raise most on the estimating side, is its first-principles engine: rather than typing in a static rate, you build each cost from labor, plant, material, and production rate, all linked so changing one input recalculates the whole estimate. Its estimating tooling rates near-perfect, too, with digitizing quantities at 99% on G2 versus an 88% average.
The other strength I'd flag is how it handles subcontractor bids. Methvin's tender portal lets you publish packages and compare incoming quotes side by side, which reviewers say takes the guesswork out of pricing, and proposal generation, closely tied to that work, is another feature scoring 99%. It also has a genuine free Starter plan, so a solo estimator can run one app at no cost before deciding to pay.
When you outgrow the Starter plan, you need more than one app, more than five projects in estimating, or a team on the platform. Methvin's Business plan is $79/month (up to five users, two apps, and Xero/SAP/JDE APIs), and Enterprise runs $179/month (unlimited users, every app, AI, and priority support).
“Methvin makes it easier to keep estimating and project information in one place. I find the detailed cost structure especially useful when reviewing labor, material, and plant requirements, and it helps me stay consistent across different parts of the estimate. The takeoff and scheduling tools also make it simpler to connect the estimate to the work that follows. Having project costs and updates accessible to the wider team improves communication, keeps everyone aligned, and makes it easier to identify issues early.”
- Methvin review, Daniel S.
Best for: Civil, infrastructure, and commercial estimators who want transparent, first-principles estimates and structured subcontractor bidding.
Not ideal for: Very small residential shops that just want a quick, simple estimate and may find the depth and learning curve more than they need.
“The learning curve can be challenging for new users, especially those unfamiliar with construction management software. Some advanced features require additional training to be fully utilized, and occasional system updates may introduce changes that take time for users to adapt to.”

Procore is one of the most widely adopted construction management platforms, with more than 4,200 G2 reviews. It's less a standalone estimator than a system for running entire projects. What stood out to me, and to reviewers, is its RFI and submittal workflow: requests for information, submittals, and correspondence all move through a structured, traceable process that keeps complex jobs from losing track of who owes what. On the numbers, it meets requirements at 91%, above the category average.
The other area reviewers lean on is financials. Teams use Procore to manage budgets, change orders, and contracts against the project, so cost commitments stay visible instead of buried in spreadsheets. On the free front: there's a free Procore account (US and Canada) for viewing projects and responding to bids, plus a 14-day trial of Procore Estimating. Beyond that, the full platform is paid, quote-based, and firmly enterprise.
As soon as you want Procore to actually run your projects. The free account only lets you view projects and respond to bids, and the Estimating trial lasts 14 days, everything past that is paid. Procore doesn't publish its pricing; it's quoted annually based on your construction volume and the modules you choose, so you'll need to request a demo to get a figure for your business.
“I like that Procore brings project management and communication into one platform. The document management feature is especially valuable for keeping drawings, plans, and project documents organized and accessible. I find RFI and submittal tracking particularly useful for following up on approvals and deadlines. The real-time project updates provide better visibility into progress and help coordinate different teams. Overall, it significantly reduces manual follow-ups and enhances project communication efficiency, making collaboration much easier.”
- Procore review, Kaushik G.
Best for: General contractors and larger teams running complex, multi-stakeholder projects who want RFIs, submittals, and financials on one platform.
Not ideal for: Solo operators or small shops after a simple, low-cost estimator. Procore is a premium, enterprise-priced platform with no free-forever full plan.
“The biggest drawback is the learning curve. With so many features and tools available, it can take time for new users to become comfortable navigating the platform.”
- Procore review, Milli H.
STACK Takeoff & Estimate does what its name says, and takeoff is the part reviewers can't stop praising. It's a cloud platform where you upload plans and measure quantities, materials, and counts right on screen. Many describe ditching hand takeoffs and cutting the time in half, or turning blueprints into a material takeoff in minutes. That speed rides on an interface people find genuinely easy: STACK scores 92% for ease of use on G2, above the 88% category average.
The second thing that kept surfacing is how easily STACK helps you navigate a big drawing set. Reviewers lean on its keyword search to pull up the exact sheets and details they need across hundreds of pages, with auto plan organization keeping everything tidy. One note on cost: there's no free-forever plan, but you can run the full Pro feature set on a 7-day free trial, with as many users as you like and no card required.
When the 7-day trial ends, and you want to keep bidding on it. STACK's Premium plan starts at $249 per user/month and Pro at $299 per user/month, both billed annually. AI takeoff accelerators and ERP connectors are paid add-ons on top.
“Everything is so much more efficient. It is easy to send and create proposals and retain data via the reports and estimate worksheet sections. I can't imagine using any other estimating software.”
- STACK Takeoff & Estimate review, Verified User in Construction
Best for: Subcontractors and estimators who do high-volume takeoffs and want to bid faster from any device.
Not ideal for: Occasional users who only need a few measurements and would rather not pay a per-user subscription once the trial ends.
“The trainings, I would find more value if there were industry-related trainings on conducting takeoffs, building assemblies, and estimates. The cost is slightly high and would find more value if we were able to pay for a license that covered multiple users. Another pain/dislike is the linear with drop feature, specifically when you're ending your measurement, the double click adds the drop, and when you try to correct it, most of the time you will delete the entire measurement and have to start over. Very frustrating.”
- STACK Takeoff & Estimate review, Christopher S.
I found free construction estimating software most useful for contractors and estimating teams that want to test a better bidding workflow before paying. It is a practical fit if you are:
A free plan or trial gives you a low-risk way to see whether the software fits your estimating process before you invest.
The first upgrade trigger is usually project or feature limits.
The second trigger is workflow complexity. Growing teams often need:
That is usually when the free option stops being enough and a paid plan starts to make sense.
Have more questions? Find more answers below.
I’d look first at Methvin if you want an ongoing free option. Its Starter plan includes one free app, with estimating, job costing, and BIM apps capped at five projects. Houzz Pro is another useful free option for residential teams that mainly need estimates, invoicing, and 3D floor planning.
I’d start with the estimating work you need to handle most often. Compare takeoff capabilities, cost estimating, bid and proposal creation, project limits, integrations, and ease of use. I’d also check whether the free access is permanent or only a trial, since that changes how useful it is for ongoing work.
For asphalt, concrete, and other civil work, Methvin is the strongest free option I evaluated because its estimating approach breaks costs into labor, plant, materials, and production rates. For more advanced heavy-civil workflows, specialized paid platforms may be a better long-term fit.
STACK Takeoff & Estimate is the strongest fit for this type of takeoff work. Its digital takeoff tools are designed for measuring and counting directly from uploaded plans, while keyword search helps estimators find relevant details across large drawing sets. Its free access comes through a 7-day trial.
I’d prioritize cloud access, shared project data, easy plan review, and collaboration between estimators and field teams. STACK is useful for cloud-based takeoffs, while Autodesk Forma is better suited to teams that need broader collaboration around drawings, models, and project information.
STACK is a strong option when takeoff data needs to move into other estimating workflows, while ConstructionOnline supports QuickBooks integration. Methvin also connects with accounting and ERP systems on its paid plans. I’d check the exact export and integration limits during the free trial before committing.
STACK, Methvin, Autodesk Forma, and Procore all support cloud-based workflows. STACK and Methvin are particularly useful for estimators who need access to takeoffs and project information from different locations, while Autodesk Forma and Procore are better suited to broader construction collaboration.
For asphalt and concrete firms, Methvin is the clearest fit among the free options I evaluated. Its civil and infrastructure focus, first-principles estimating, and support for labor, plant, material, and production-rate inputs make it well suited to complex estimating workflows beyond initial setup.
Methvin has the most structured setup among the tools I evaluated because its first-principles estimating method builds costs from labor, plant, materials, and production rates. G2 reviewers also mention a learning curve, especially for teams moving from spreadsheets, so setup and onboarding should factor into your decision.
The review data shows established ongoing use for platforms such as Autodesk Forma, Procore, STACK, and ConstructionOnline, but most only offer free trials rather than permanent free access. Methvin is the main free-plan option if you want to keep using limited estimating functionality without an immediate subscription.
Autodesk Forma and Procore are the strongest options for keeping project information centralized across teams, although both mainly offer trial-based or limited free access. Their collaboration and project-control workflows can help reduce errors caused by outdated drawings, missed updates, or disconnected information.
Handoff, ConstructionOnline, STACK, Methvin, Autodesk Forma, and Procore all receive strong G2 feedback for different workflows. I’d choose based on the job: Handoff for fast residential estimates, STACK for takeoffs, Methvin for detailed civil estimates, and Procore or Autodesk Forma for larger, more complex teams.
After comparing these tools, what stood out to me is how different “free” can look in construction estimating. Methvin and Houzz Pro give you ongoing free access to specific workflows, while tools like STACK, Handoff, ConstructionOnline, Autodesk Forma, and Procore are better treated as evaluation windows before a paid commitment.
That means the best choice comes down to what you need to prove before spending. If takeoffs are your priority, STACK is worth a closer look. If you want faster residential estimates, Handoff stands out. Methvin makes more sense for detailed civil estimating, while Procore and Autodesk Forma fit larger teams that need broader project coordination.
I’d use the free access to answer one question: Does this tool make estimating faster, clearer, or more reliable for the way you actually work? If the answer is yes, the upgrade decision becomes much easier.
