Best Estimating Software for General Contractors

For a general contractor, estimating software is only useful if it keeps the bid under control. A GC estimate has to tie together drawings, addenda, scope sheets, subcontractor quotes, alternates, allowances, exclusions, markups, cost codes, and the handoff after award. Faster plan measurements help, but they do not fix the GC estimating problem on their own.

Disclosure: Some links on Contractor Software Hub are affiliate links. If you sign up through one, I may earn a small commission at no extra cost to you. My recommendations do not change based on that.

Right for: commercial GCs, residential GCs, custom home builders, remodelers, design-build firms, and estimating teams comparing software for takeoff, bid packages, scope review, subcontractor quotes, estimate revisions, cost-code handoff, and current pricing.

Not for: single-trade subcontractors that only need faster measurements, owner-operators still pricing a few simple jobs accurately in spreadsheets, or buyers expecting software to fix estimating before the company has agreed on cost codes, markup rules, scope templates, and approval authority.

How to Choose Estimating Software for General Contractors

Start by separating three jobs that often get lumped together: takeoff, estimating, and bid management. Takeoff answers how much. Estimating turns that quantity into cost and margin. Bid management tracks subcontractor scope, exclusions, alternates, and the package the project team receives after award. Most GCs need all three, but they do not always need all three in one product.

If the company is a commercial GC already using Procore, or seriously evaluating Procore as the project system, start with Procore Estimating. The current Procore pricing page says pricing depends on the products purchased and annual construction volume, with an upfront annual fee. It also emphasizes unlimited users, unlimited data and storage, and support included for customers. That pricing model is built for broad rollout. It makes sense when estimating is part of that wider Procore decision, not a side purchase for one estimator.

If the company is a residential GC, custom home builder, remodeler, or design-build contractor, the pain usually shows up somewhere else. A bad estimate is not always a missed quantity. It can be a homeowner approving a change by text, a selection getting priced late, a schedule update that no longer matches the estimate, or a change order that never reaches accounting. Buildertrend is stronger in that environment because estimating sits near the client portal, selections, schedules, change orders, and project financial workflow. Its current pricing page uses tailored pricing and a demo path, so compare the quote in writing against other tools.

If the bottleneck is plan measurement and estimate speed, look at STACK before buying a full construction management suite. STACK publishes a free account and paid Takeoff and Estimate plans billed annually per user. It runs in the browser and centers on plan documents, takeoff organization, item and assembly libraries, overlays, markups, and shared access. That fit is practical for estimators who need to work from PDFs and produce bid quantities faster without moving the whole company into a new project management platform.

PlanSwift and Sage Estimating are more conditional. PlanSwift is still useful when a dedicated estimator wants a focused Windows desktop takeoff workflow and can justify a $2,000/year Professional subscription. It is not the answer if cloud access and collaboration are the main needs. Sage Estimating belongs in enterprise conversations where Sage accounting, cost codes, historical databases, and back-office controls matter more than a light estimator experience. It is not a shortcut for small GCs that need quick proposals.

Do not rank these products by starting price alone. A free STACK account may be enough to test takeoff, but paid estimating starts much higher. Buildertrend and Procore require quotes, yet either one may replace several disconnected systems if the company is ready for that change. PlanSwift is easy to price, but bid management may still live somewhere else. Sage can be the right call for a large finance-led construction operation and the wrong call for a smaller team trying to clean up bids next month.

Quick Picks

Do You Need This Yet?

GC estimating software is worth paying for when the bid process stops being trustworthy. A spreadsheet can still work for a small GC with a few familiar jobs, known subs, and a short handoff to the field. It breaks down when the estimate has to serve sales, estimating, PMs, supers, accounting, and purchasing at the same time.

• You do not need it yet if one person can still price the job, compare sub quotes, track revisions, communicate exclusions, and hand the estimate to the field without losing details.
• You need it now if addenda create duplicate takeoffs, bid tabs live in several spreadsheets, subcontractor scopes are hard to compare, or PMs keep asking what was carried in the final number.

The in-between stage is where many GCs sit. You may not need Procore or Sage yet, but you may need STACK if plan measurement and bid quantities are choking the estimating department. A residential GC may not need a heavy estimating database, but Buildertrend can make sense when approvals and change orders are getting lost between the estimate and the homeowner. A commercial GC already on Procore may save more time by adding Procore Estimating than by forcing another standalone takeoff tool into the handoff.

Before spending money, name the failure point. If it is takeoff speed, demo STACK or PlanSwift. If it is client approvals, demo Buildertrend. If it is project handoff across the company, demo Procore. If it is Sage accounting control, evaluate Sage Estimating with finance in the room.

Product Reviews

1. Procore Estimating - Best for large commercial GCs already on Procore

What stands out: Procore Estimating fits commercial GCs that want estimating inside the same system as project management. Faster takeoff is part of the appeal, but the bigger benefit is keeping drawings, bid packages, RFIs, submittals, revisions, and the awarded project record closer together. For a GC with multiple PMs, supers, project engineers, subs, and office users touching the same job, that connection matters.

Procore’s current pricing page does not publish a fixed monthly list price. It says pricing depends on the products you need and the amount of construction you do, with an upfront annual fee by product and annual construction volume. It also states that Procore includes unlimited users, unlimited data and storage, and support for customers. That matters because a GC platform only pays off when the team actually uses it. If only one estimator has access, the handoff benefit is limited.

Procore is strongest when estimating is part of a broader Procore decision. A commercial GC already using Procore for project management should test whether Procore Estimating cuts duplicate entry and gives operations a cleaner final bid. A GC not using Procore should move more carefully. Buying an enterprise platform because the estimating module looks attractive can create a bigger implementation project than the team expected.

Where it falls short: Procore is heavy for teams that only need plan takeoff or a spreadsheet replacement. The price requires a custom quote, and the buying process should include implementation scope, products included, annual construction volume assumptions, renewal terms, and how estimating data moves into the rest of the system. The learning curve is real because the value depends on changing how people work, rather than simply adding another tool.

Pricing: Custom quote. Procore says pricing depends on products and annual construction volume, with an upfront annual fee. The current pricing page also states unlimited users, unlimited data and storage, and support are included for customers. Ask for the estimating module, project management products, annual volume assumptions, implementation, renewal, support, and any future product add-ons in writing.

Best for: commercial GCs already using Procore, or larger GCs ready to make estimating part of a broader Procore project control system.

2. Buildertrend - Best for residential GCs and custom home builders

What stands out: Buildertrend is the strongest fit in this group for residential GCs, custom home builders, remodelers, and design-build contractors that need estimates tied to homeowner communication. Residential estimating often breaks after the estimate is accepted: a customer changes a selection, approves a change informally, asks for a schedule update, or questions an invoice. Buildertrend keeps that customer-facing work closer to the estimate and project record.

The current Buildertrend pricing page uses a tailored pricing model and asks buyers to connect with the team for the best solution and price. It also says unlimited users are included in pricing. That can be useful for residential construction companies where owners, salespeople, project managers, office staff, and supers all need access. It also means buyers should not rely on older public pricing references. The written quote is the price.

Buildertrend is not trying to be the fastest commercial takeoff product. It makes more sense when the estimate needs to turn into a proposal, selection record, schedule, change order, invoice path, and client communication thread. A custom home builder or remodeler may get more value from that residential workflow than from a stand-alone measuring tool.

Where it falls short: If the GC only needs digital plan takeoff, Buildertrend may be more platform than necessary. Commercial GCs that need subcontractor bid leveling, bid packages, formal scope comparison, or enterprise cost-code controls should compare it against Procore, STACK, or Sage rather than treating it as a universal GC estimator. Test mobile workflow and financial setup with real jobs before rollout.

Pricing: Custom quote. Buildertrend says pricing is tailored to the business and recommends scheduling a demo. Its pricing page also says unlimited users are included. Ask for a written proposal that lists included features, user assumptions, annual-pay discounts if any, onboarding, payment processing, cancellation, renewal, and data export.

Best for: residential GCs and custom home builders that need estimating connected to client communication, selections, change orders, schedules, and project financial workflow.

3. STACK - Best cloud takeoff and estimating without full PM

What stands out: STACK is the first demo I would book when the estimating team wants cloud takeoff and estimating, not a full company operating system. It runs in the browser, which helps estimators work from different locations and keep plan documents in one shared place. The current pricing page describes unlimited projects and documents, cloud access, unlimited viewer seats, takeoff tools, takeoff organization, item and assembly libraries, overlays for drawing versions, markup, plan collaboration, metric and imperial units, and demo support.

STACK’s pricing is clearer than most GC platforms. It lists a free account, Takeoff at $249 per user per month billed annually, and Estimate at $299 per user per month billed annually. The free account can help you evaluate the workflow, and the page says new users can use Pro-level features on any project for 7 days. Still, model the paid version because most active estimating teams will need more than a free account.

STACK is strongest when the GC already has project management and accounting handled somewhere else. Estimators can use it to measure plans, organize quantities, work with item libraries, compare plan versions, and build estimate detail without forcing PMs and supers into a new platform. That makes it a good middle path for GCs that are not ready for Procore or Sage but have outgrown manual takeoff.

Where it falls short: STACK is not a full GC operating system. Do not assume it will replace project management, accounting, purchasing, subcontractor prequalification, or enterprise cost control. Test alternates, allowances, bid-leveling needs, scope exclusions, cost-code exports, and how the final estimate reaches PMs and accounting. Also ask whether onboarding fees apply and how many paid estimator seats are needed.

Pricing: Free account available. Takeoff is listed at $249/user/month billed annually. Estimate is listed at $299/user/month billed annually. A one-time onboarding fee may apply. Ask whether all needed takeoff, estimate, viewer, AI, library, export, and support features are included in the quoted plan.

Best for: estimating teams that need cloud takeoff and bid quantity workflow without replacing the company’s project management or accounting stack.

4. PlanSwift - Best desktop takeoff for high-volume estimators

What stands out: PlanSwift still matters because some estimators want a focused desktop takeoff tool and do not need a larger platform around it. The product is built for on-screen takeoff, quantity extraction, and trade-specific workflows through templates and plug-ins. For a high-volume estimator who spends most of the week measuring plans, a dedicated desktop interface can still be productive.

The current PlanSwift pricing page lists PlanSwift Professional at $2,000 for an annual subscription. It says the subscription includes support, software updates, and 2 hours of training. The page also promotes a free trial path. That is a different budget than older perpetual-license references, so treat PlanSwift as an annual software cost.

PlanSwift is the most focused tool in this list, which can be a strength or a limitation. If the estimator wants fast takeoff from a workstation and the company already has a process for bid tabs, proposals, PM handoff, and accounting, PlanSwift can fit. If the team needs several people reviewing plans from different locations, cloud-based collaboration, customer approvals, or connected project controls, STACK, Buildertrend, or Procore may be a better first demo.

Where it falls short: PlanSwift is not a full estimating department system for every GC. It does not handle subcontractor bid management, residential client communication, project management, or accounting handoff on its own. It also requires comfort with a desktop-first workflow. Before buying, test the exact plan types, plug-ins, assemblies, export format, and estimator workstation setup.

Pricing: PlanSwift Professional is listed at $2,000/year. The annual subscription includes support, software updates, and 2 hours of training. A trial path is available. Ask whether any plug-ins, training, extra users, migration help, or support requirements change the first-year cost.

Best for: dedicated estimators who mainly need fast desktop takeoff and already have a separate system for bids, projects, and accounting.

5. Sage Estimating - Best for enterprise Sage construction accounting teams

What stands out: Sage Estimating belongs in this roundup for larger GCs where estimating has to line up with the back office. The value is not a lighter interface or a quick trial. It is cost-code structure, estimating databases, accounting handoff, and controls that fit a Sage-centered construction finance environment. If the company already relies on Sage construction accounting, Sage Estimating may fit better than a stand-alone takeoff tool that creates another disconnected data source.

Sage’s current construction product pages do not give a simple public list price for Sage Estimating. Sage 300 Construction and Real Estate materials frame subscription pricing as available and route buyers to request more info. That matches how enterprise construction software is usually bought: scope the products, integrations, implementation, users, database needs, and support before quoting. Buyers should avoid treating third-party estimates as official Sage list pricing.

The fit is narrow but real. A large GC with a mature accounting department, historical cost data, formal estimating standards, and Sage cost codes may care more about control than speed. Sage Estimating can be evaluated as part of a broader Sage construction stack. Smaller GCs that need a faster bid tomorrow will usually get there sooner with STACK, PlanSwift, or a residential platform such as Buildertrend.

Where it falls short: Sage Estimating can be too much system for a company that has not standardized its cost codes, estimate database, approval process, and accounting workflow. It usually takes scoping, implementation, training, and careful database setup. If the estimating team is mainly frustrated by PDF takeoff speed, Sage is probably not the first demo.

Pricing: Custom quote / request info. Treat Sage Estimating as scoped subscription pricing through Sage or a Sage partner. Ask for product scope, Sage 300 CRE relationship, implementation, database conversion, training, support, renewal terms, and data export in writing.

Best for: large commercial GCs and construction accounting teams already committed to Sage systems and formal cost-code control.

Pricing and Fit Comparison

Pricing only helps when you tie it to the way the job moves through the company. STACK and PlanSwift are easier to budget because they publish starting numbers, but they do not replace a full PM or accounting system. Procore, Buildertrend, and Sage require quotes, but they may reduce duplicate systems if the company is ready to keep estimating, project records, approvals, and back-office workflow in one platform family.

For every vendor, calculate first-year cost and renewal cost. Include paid estimator seats, viewer or field users, annual construction volume, billing term, onboarding, training, data import, takeoff libraries, cost database setup, support, payment processing if applicable, accounting integration, add-ons, cancellation terms, renewal caps, and data export. For a GC, also count any tools that remain after the purchase.

GC Estimating Software Buying Checklist

Bring real work into the buying process. Do not let the demo stay in a polished sample account. Use one recent bid that went well, one bid that had addenda, one bid with alternates, one bid with confusing subcontractor exclusions, and one awarded project where the PM had to ask estimating for clarification. The demo should prove the software can handle the messy parts, because clean quantity takeoff is the easy portion.

• Test drawings and revisions. Upload a real plan set, issue an addendum, compare versions, and confirm how quantities, notes, and scope changes are preserved.
• Test bid packages and scopes. Build trade packages, subcontractor quote records, inclusions, exclusions, alternates, allowances, and bid leveling views.
• Test estimating standards. Confirm cost codes, assemblies, item libraries, labor rates, equipment, burden, taxes, markup, contingency, and overhead rules.
• Test handoff. The final estimate should become a project budget, schedule input, purchasing reference, accounting export, and PM record without the office rebuilding it by hand.
• Test permissions. Decide who can edit cost items, approve markups, view subcontractor quotes, export data, change templates, and issue final proposals.
• Test reporting. Compare estimated cost against awarded value, buyout, change orders, and actual job cost. If the tool cannot help the team learn from past bids, the database will age quickly.
• Test exit risk. Ask how to export plans, takeoffs, estimates, bid tabs, vendors, cost codes, assemblies, customer data, project files, and audit history if the company leaves.

Before signing, decide who owns implementation. Estimating software fails when everyone assumes someone else will build templates, clean cost codes, update material prices, train PMs, and police the handoff. Assign an owner for setup, QA, template maintenance, estimator training, and post-award handoff rules.

FAQ

What is the best estimating software for most general contractors?

For large commercial GCs already on Procore, Procore Estimating is the best fit because it connects estimating with project controls and team records. For residential GCs and custom builders, Buildertrend is usually a better fit because estimates connect to client communication, selections, change orders, and schedules. For teams that mainly need cloud takeoff and estimating, STACK is the best first demo.

How much should a GC budget for estimating software?

Budget depends on whether the company needs takeoff, estimating, bid management, or a full platform. STACK starts with a free account, with Takeoff listed at $249/user/month billed annually and Estimate at $299/user/month billed annually. PlanSwift Professional is listed at $2,000/year. Procore, Buildertrend, and Sage Estimating require custom or request-info pricing, so buyers should get written quotes before comparing total cost.

Is Procore Estimating worth it if we do not use Procore yet?

Usually only if the company is ready to evaluate Procore as a broader project control platform. Procore Estimating makes the most sense when drawings, bids, RFIs, submittals, project records, and team communication can live in the same Procore environment. If the only pain is measuring plans faster, STACK or PlanSwift is a lower-friction first demo.

Is Buildertrend enough for commercial GC estimating?

Buildertrend can work for residential GCs, remodelers, custom home builders, and design-build firms. It is not the strongest first choice for commercial GCs that need formal subcontractor bid leveling, enterprise cost-code controls, or heavy bid package management. Commercial buyers should compare it against Procore, STACK, and Sage based on the exact bid workflow.

Should we choose STACK or PlanSwift for takeoff?

Choose STACK when browser access, shared plan documents, cloud takeoff, viewer seats, plan overlays, and estimating workflow matter. Choose PlanSwift when one or more estimators prefer a focused desktop takeoff workflow and the company already has another place for bid tabs, project management, and accounting. The demo should use the same plan sets your estimators handle every week.

Does Sage Estimating replace takeoff software?

Sage Estimating should be evaluated as an enterprise estimating and cost-control system, especially for Sage-centered construction accounting teams. It may not be the fastest answer for basic plan measurement. If the main need is takeoff speed, compare STACK and PlanSwift first. If the main need is Sage accounting handoff and cost-code discipline, Sage belongs in the demo list.

What is the biggest mistake when buying GC estimating software?

The biggest mistake is buying around a feature checklist instead of a real bid path. A GC should test drawings, revisions, takeoff, scopes, sub quotes, alternates, allowances, cost codes, markup, proposal output, and post-award handoff in the same demo. If the final process still depends on hidden spreadsheets and PM follow-up calls, the software has not fixed the core problem.

Bottom Line

Procore Estimating is the best enterprise fit for commercial GCs already on Procore or ready to connect estimating with project controls, drawings, RFIs, submittals, and team records. Buy it as part of a platform decision, not as a casual takeoff add-on.

Buildertrend is the stronger fit for residential GCs and custom builders where client approvals, selections, change orders, schedules, and homeowner communication drive the estimate. STACK is the best first demo for teams that need cloud takeoff and estimating without replacing project management. PlanSwift remains useful for focused desktop takeoff. Sage Estimating is a conditional pick for larger GCs already committed to Sage construction accounting and formal cost-code control.
