GC estimating is a different problem than subcontractor estimating. You’re not just doing takeoffs on your own scope. You’re managing bid packages from multiple subs, leveling bids to compare apples to apples, tracking scope gaps, and assembling a complete project cost picture from pieces that don’t always fit cleanly together. The software needs to handle that coordination, not just generate numbers.

Most estimating software reviews treat all contractors the same. This one is specifically for general contractors running competitive bids on commercial, institutional, or multi-phase residential projects.

Procore Estimating – Best for Large Commercial GCs Already on Procore

If your operation is already running Procore for project management, the estimating module makes real sense. Bid packages connect directly to drawings, RFIs, and submittals. When a scope item changes, it flows through the whole project. For a commercial GC managing multiple active bids on complex projects, that integration is worth something.

If you’re not already in the Procore ecosystem, the math doesn’t work. The estimating module only delivers its value as part of the full platform, and the full platform is a significant investment. I pulled the pricing page: Procore doesn’t publish numbers publicly, which is always a sign you’re in enterprise territory. Implementation runs $5,000 to $15,000 on top of the subscription, and that’s before training your team.

Multiple G2 reviewers running mid-size commercial GC operations note that once the system is set up, it’s genuinely hard to go back to anything else. The complaint pattern that shows up repeatedly is the ramp-up time: reviewers mention 3 to 6 months before the estimating module feels natural, and several mention that the value doesn’t click until the whole team is using it consistently.

Pricing: Enterprise only (no published rates). Implementation cost is additional.

Best for: Commercial GCs at $10M+ annual revenue already committed to Procore across the whole operation.

Buildertrend – Best for Residential GCs and Custom Home Builders

Buildertrend’s estimating is built around the residential workflow, and it shows. The change order approval process through the client portal is the standout feature. Homeowners get a clean, professional interface to review and approve changes, which cuts down on the back-and-forth that kills residential project margins. If you’re doing custom homes or design-build work and your clients expect that experience, Buildertrend handles it well.

Buildertrend does not publish pricing on its website. You have to contact their sales team to get a quote, which means you are going into a sales conversation before you know what you will pay. Based on what contractors report in forums, plan for significant monthly costs once you include the tier that has the features you actually need. That is not unreasonable for a residential GC doing $1M+ in work, but confirm current pricing directly with Buildertrend before committing.

One Capterra reviewer running a 12-person remodeling company put it plainly: the client tools are worth the price, but the estimating side alone isn’t deep enough to justify it if that’s all you’re using it for. Several G2 reviewers echo this: Buildertrend is a client communication and project management tool with estimating built in, not the other way around.

Pricing: Not publicly listed — contact Buildertrend for a custom quote.

Best for: Residential remodeling GCs and custom home builders who need client-facing tools connected to their estimates and change orders.

STACK – Best Cloud-Based Takeoff Without Full PM Software

STACK does one thing well: fast digital takeoffs from PDF plans in a browser, with no software to install and no hardware requirements beyond a laptop. For a GC doing competitive bidding across multiple project types who doesn’t need (or want) a full project management platform attached, this is a clean option.

The free plan covers basic measurements. Starter at $69 a month gets you more tools and collaboration features. Professional starts at $149 a month and unlocks the features most GCs actually need for serious bid work. The pricing is straightforward compared to most of the competition in this space.

The limitation worth knowing: STACK is a takeoff tool, not a full estimating system. It handles the measurement side well. The cost database and bid assembly side is less developed than dedicated estimating platforms. A few G2 reviewers in the commercial GC space mention that STACK handles the takeoff portion of their process and they use a separate tool for the cost side. That two-tool workflow adds friction.

Pricing: Free plan available | Starter $69/mo | Professional from $149/mo

Best for: Competitive bidding GCs who need faster takeoffs and cloud storage for plans, without committing to a full PM platform.

PlanSwift – Best Dedicated Takeoff Tool for High-Volume Estimators

PlanSwift is the tool contractors reach for when they’re doing a lot of takeoffs and speed matters. The desktop software is purpose-built for plan measurement and quantity extraction. Users who have learned it well report completing takeoffs 3 to 5 times faster than manual methods. That’s a meaningful number if you’re pricing 20 or 30 bids a month.

The business model is a perpetual license at roughly $1,749 per seat, which means you own the software. There’s also a subscription option. For a GC who estimates regularly and wants to own the tool rather than pay forever, the perpetual license makes financial sense within two years.

The trade-off is that PlanSwift is desktop-based Windows software with a UI that hasn’t changed much in years. There’s no mobile access, no cloud storage for your plans, and no collaboration features. Multiple G2 reviewers mention that it works exactly as described but feels dated compared to browser-based competitors. If your estimators are mobile or your team collaborates on bids, this creates real friction.

Pricing: ~$1,749 perpetual license per seat (subscription options available)

Best for: GCs with dedicated estimators doing high-volume bids who need speed and precision over collaboration features.

Sage Estimating – Best for Enterprise Operations in the Sage Ecosystem

Sage Estimating is built for large commercial GCs who are already using Sage 300 Construction & Real Estate for financials. The integration between estimating and accounting is the value proposition. When an estimate becomes a project, the cost codes flow through without manual entry. For an operation doing tens of millions in revenue with a full accounting department, that matters.

The downside is everything else about the implementation experience. Sage Estimating typically requires a certified consultant to set up, which adds $5,000 to $15,000 before anyone on your team has touched the software. The learning curve is significant: several Capterra reviewers mention 6 months before the system felt natural, and a few mention relying on the consultant longer than expected because the documentation is poor.

This is not software you buy and start using next week. It’s an enterprise implementation project that pays off if your volume and existing Sage investment justify it.

Pricing: Enterprise pricing (contact Sage for a quote; typically $3,000+/year)

Best for: Large commercial GCs ($50M+ revenue) already running Sage 300 who need estimating connected directly to their financial system.

Common Questions

What is the difference between takeoff software and estimating software?

Takeoff software measures quantities from plans: square footage, linear feet, count of fixtures. Estimating software takes those quantities and builds a complete project cost — applying unit costs, labor rates, markups, and overhead. Most modern GC platforms do both, but some tools (like STACK and PlanSwift) focus primarily on the takeoff side and assume you will handle the cost assembly separately.

What estimating software do most GCs actually use?

It varies significantly by company size. Small residential GCs (under $2M revenue) often use a spreadsheet or Buildertrend. Mid-size commercial GCs ($2M-$20M) more commonly use STACK or PlanSwift for takeoffs, sometimes paired with a spreadsheet cost model. Large commercial GCs running $20M+ are the main Procore and Sage customers. The enterprise tools require dedicated estimating staff to get value from them.

Can I use Excel for GC estimating?

Yes, and many GCs do. The trade-off is speed and error risk at scale. Excel works well for simple bids with predictable scope. It breaks down on complex commercial projects with multiple bid packages, scope gaps to track, and leveling to do across 10 or 15 sub proposals. If you are running more than 5 or 6 concurrent bids, a dedicated takeoff tool almost always pays for itself in time savings.

Does estimating software integrate with accounting?

Some do, some don’t. Procore and Sage Estimating are the strongest on accounting integration (connecting to Procore financials and Sage 300 respectively). Buildertrend integrates with QuickBooks. STACK and PlanSwift are primarily standalone tools — you export from them into your accounting system. If accounting integration is critical, confirm the specific integration before buying.

Pricing Comparison: What General Contractors Should Expect

Pricing is one of the biggest filters in this category because the gap between a takeoff tool and an enterprise estimating platform is huge.

• Under $200 per month: STACK is the clearest fit if you mainly need fast takeoffs and cloud collaboration.
• Mid-market custom quote: Buildxact and Buildertrend make the most sense for residential builders who want estimating tied to client communication or project management.
• Perpetual-license option: PlanSwift still appeals to estimators who would rather buy once and use the tool for years.
• Enterprise pricing: Procore and Sage require a larger budget and usually an implementation commitment, not just a monthly subscription.

If you also need stronger proposal presentation, it is worth pairing your estimating workflow with one of the tools in our best proposal software for contractors guide.

How to Choose Estimating Software as a General Contractor

The right answer depends less on the software brand and more on how your estimating process actually works.

• If you run residential custom builds or remodels: Buildertrend or Buildxact usually make more sense than a heavy commercial estimating stack because the client communication and change-order workflow matters as much as the estimate.
• If you run competitive commercial bids: STACK is the more practical starting point unless you are already committed to Procore or Sage.
• If you are still very small: Start with the options in our estimating software for small contractors guide instead of overbuying for complexity you do not have yet.
• If presentation is losing you jobs: Improve the estimating handoff with better client-facing proposal tools, not just a stronger takeoff tool. Our proposal software roundup is the next place to look.

If you want a broader starting point before narrowing into estimating-only tools, see our best contractor software hub.

The most expensive mistake GCs make with estimating software is buying an enterprise platform before they need it. Here’s the honest framework:

If you’re doing residential work, custom homes, or design-build projects under $5M a year, Buildertrend is probably the right answer. The client tools pay for themselves.

If you’re doing competitive commercial bids and need fast takeoffs without committing to an ecosystem, STACK at $149 a month handles the measurement side well. Add a cost database tool if your pricing needs are complex.

If you estimate a lot of jobs and speed is the bottleneck, PlanSwift’s perpetual license model is worth the upfront cost. You’ll recoup it within a year if you’re pricing regularly.

Procore and Sage are correct answers for specific operations at specific stages. If you’re not already in their ecosystems, starting with them is a mistake. The implementation cost and learning curve will bury you before you see the value.

Methodology

This roundup was evaluated from a general contractor perspective rather than a subcontractor perspective. I weighted bid leveling, takeoff usability, estimating speed, pricing transparency, and how well each platform supports either competitive bid work or residential GC workflows. I also used current public pricing where available and recent review patterns from contractor users to identify where each tool is strong versus where it creates operational friction.

The Bottom Line

For most GCs reading this, the right starting point is STACK or Buildertrend depending on whether your work skews commercial/bidding or residential/client-facing. Both have free trials. Both are usable within a week. Neither requires an implementation consultant.

Procore and Sage are real tools for the right operation. Just make sure you’re at the stage where you can absorb the implementation cost and the learning curve without it disrupting active projects.
