Procore is a project management platform used by a significant share of mid-market and large commercial GCs. In 2023, Autodesk completed its acquisition of Procore's main estimating competitor, ProEst, creating a situation where the two dominant construction software platforms are both pushing their users toward the same estimating solution: Autodesk Construction Cloud with ProEst.
Not every firm using Procore for project management wants ProEst for estimating. Some firms are already satisfied with a standalone estimating tool. Some are specifically trying to stay outside the Autodesk pricing and ecosystem structure. Some are $5M to $30M shops for whom ProEst's per-seat pricing doesn't pencil out.
This article is for commercial GCs using Procore for project management who need to understand their estimating options outside the Autodesk path. Procore does not own your estimating workflow, and there are viable alternatives.
For the full field of estimating alternatives, see the four-way comparison of STACK, PlanSwift, ProEst, and BidFlow.
What Procore Does and Doesn't Do for Estimating
Procore is a project management platform: bidding coordination, RFI management, submittals, daily logs, punch lists, change order tracking, and financial management. It has a bid management module that handles the ITB process — inviting subs, tracking responses, managing the bid leveling — but it is not a construction estimating system.
Procore's estimating capability is limited to managing the sub quote process and basic cost tracking. It does not do quantity takeoff, assembly-based estimating, cost library management, or firm-specific cost calibration. The estimating tools it integrates with natively are primarily within the Autodesk Construction Cloud ecosystem.
The result: firms using Procore for project management have to make a separate estimating decision. Procore's platform doesn't dictate that decision, even though Autodesk's market position suggests otherwise.
What ProEst Does Well
Before covering the alternatives, be honest about why ProEst is the natural first consideration for Procore users.
- Full assembly-based estimating system. ProEst is a mature platform with assemblies, cost databases (RSMeans included), bid-day workflow, and sub coverage tracking. For a firm that needs a complete estimating system with vendor-supplied cost data, ProEst covers the full workflow.
- Autodesk Construction Cloud integration. If your firm is moving toward a broader Autodesk stack, ProEst's integration with BIM 360 and other ACC tools is real. The data flow between ProEst's estimate and the ACC project management layer works.
- Established market position. ProEst has been in the mid-market estimating space since before the acquisition. The platform is stable, has real training resources, and a large enough user base that you can find practitioner guidance online.
Why Firms Look for Procore-Compatible Alternatives to ProEst
The reasons practitioners report for looking outside ProEst fall into three categories:
Pricing. ProEst per-seat licensing in 2026 runs $2,400 to $4,800 per estimator per year. For a 3-estimator commercial GC, that's $7,200 to $14,400 annually, before implementation. For a 5-estimator firm, $12,000 to $24,000. This is on top of what the firm already pays Procore. Some firms run the math and decide the combined Procore plus ProEst licensing cost is not defensible at their revenue scale.
Ecosystem lock-in. Moving from ProEst to another estimating tool after 2 to 3 years means migrating your assembled cost library out of ProEst's schema. Autodesk platforms historically make this difficult. Firms that are already using Procore and considering ProEst should ask explicitly: "What does a migration out of ProEst look like in 5 years?" If the answer is unclear or expensive, that's worth factoring into the decision.
Overkill for smaller shops. A 1 to 4 estimator firm bidding $5M to $30M of commercial work per year is buying significantly more system than they need with ProEst. The 3 to 4 month onboarding timeline, the assembly build required to realize full value, and the enterprise-calibrated pricing don't match the workflow of a small commercial GC with a 3-estimator team bidding 35 jobs per year.
Standalone Estimating Alternatives That Work Alongside Procore
None of the alternatives below have native Procore integration. They operate alongside Procore, handling estimating while Procore handles project management. The workflow hand-off is a data export from the estimating tool into Procore's budget module — which is a manual step, but it's a 15-minute step, not a 15-day integration project.
STACK
Cloud-native takeoff and estimating, $1,800 to $3,600 per seat per year. STACK's takeoff layer is best-in-class for cloud workflow: fast plan upload, responsive markup tools, multi-user collaboration for 2 or more estimators on the same job. The estimating layer is more recent and requires setup, but for firms where takeoff is the bottleneck, STACK is a strong standalone choice alongside Procore's project management.
PlanSwift
Trimble's takeoff-focused platform, $1,500 to $2,800 per seat per year. PlanSwift is a takeoff tool with a light estimating layer attached. For firms where plan measurement is the primary estimating bottleneck and the estimate build happens in Excel or a separate system, PlanSwift is a leaner, cheaper option than ProEst or STACK. Not a full estimating system on its own.
BidFlow
AI-powered calibration against your past bids. $199 per month flat (or $1,990 per year), unlimited estimators. The model is different from STACK and PlanSwift: instead of building a cost library from scratch inside the tool, BidFlow reads your past estimates in Excel or similar format, extracts your firm's unit costs, markup structure, and cost categories, and uses that as the basis for new estimates.
For a Procore firm that does not want to go deeper into the Autodesk ecosystem, BidFlow is the cleanest alternative: no per-seat pricing, no assembly build, no Autodesk dependency. It runs entirely independent of the Autodesk stack.

The Procore Plus BidFlow Combination
For a commercial GC that uses Procore for project management and needs a standalone estimating tool outside the Autodesk stack, Procore plus BidFlow is the combination that most mid-market firms in the $5M to $50M range find easiest to operate.
BidFlow handles estimating: calibration against your past bids, estimate production in your firm's format, cost structure that reflects your actual subs and labor rates. Procore handles project management: budget input, sub coordination, RFIs, submittals, change orders. The hand- off between them is an export of the finalized bid budget into Procore's budget module.
There is no native integration between BidFlow and Procore. The workflow is: produce the estimate in BidFlow, export the line-item budget, import into Procore's budget. For most firms, this is a 15 to 30 minute step per awarded project, not a workflow blocker.
FAQs
Does Procore have a built-in estimating tool?
Procore has a bid management module that handles the subcontractor invitation process, quote tracking, and basic bid leveling. It does not have quantity takeoff, assembly-based estimating, or cost library management. It is a project management and bid coordination platform, not an estimating system. Firms using Procore need a separate estimating tool for the cost build.
Does Procore integrate with estimating tools other than ProEst?
Procore's marketplace lists integrations with several estimating tools including STACK and others. Native integration depth varies. Most mid-market firms using standalone estimating tools alongside Procore do the hand-off via a budget export into Procore's budget module rather than relying on a native API integration. This is typically a 15 to 30 minute step per awarded project and is not a significant workflow constraint for most firms.
Why would a Procore user not pick ProEst?
Three common reasons: pricing (ProEst at $2,400 to $4,800 per seat per year on top of Procore licensing is a real cost for smaller firms), ecosystem concern (firms that don't want to go deeper into the Autodesk stack for strategic or pricing reasons), and firm size (a 1 to 4 estimator firm bidding $5M to $20M of work per year often has more system than they need with ProEst's full platform and 3 to 4 month onboarding).
What is the cheapest construction estimating software that works alongside Procore?
BidFlow at $199/month flat (or $1,990/year) unlimited estimators is the lowest-cost full estimating tool in the mid-market space. Excel is free but requires full manual build per estimate. PlanSwift at $1,500 to $2,800 per seat per year is cheaper per-seat than ProEst but is a takeoff tool, not a full estimating system. STACK at $1,800 to $3,600 per seat per year is cheaper than ProEst but still per-seat.
Does BidFlow integrate with Procore?
Not natively. The workflow is export the finalized estimate budget from BidFlow and import into Procore's budget module. For most firms this is a 15 to 30 minute step per awarded project. It is not a seamless API integration. For firms that require deep native integration between their estimating tool and Procore, this is a real limitation.
What does a Procore firm typically pay for estimating software per year?
It varies significantly by tool choice. ProEst for 3 estimators: $7,200 to $14,400 per year. STACK for 3 estimators: $5,400 to $10,800. PlanSwift for 3 estimators: $4,500 to $8,400. BidFlow: $1,990 per year regardless of estimator count. On top of Procore's licensing (which itself runs several thousand to tens of thousands per year depending on firm size), the combined software cost for a 3-to-5 estimator commercial GC can run $20,000 to $50,000 annually before factoring in implementation.
Is STACK a better alternative to ProEst for a Procore user?
For a Procore user whose estimating bottleneck is the takeoff process specifically, STACK is a strong alternative. STACK's cloud takeoff is faster and more collaborative than ProEst's, and the per-seat pricing is lower. For a firm where the cost build is the bottleneck and takeoff is already fast, STACK's main differentiator (cloud takeoff) is less relevant. BidFlow fits that case better if most of the work is in project types the firm has bid before.
Evaluate Before Committing
The cleanest evaluation path for a Procore firm weighing estimating options: use BidFlow's 3 free estimates to see whether calibration-based estimating fits your workflow before paying anything. Upload a past bid, produce a new estimate, compare to your actual bid. If it matches closely, you have a concrete alternative to ProEst. If it doesn't, you've spent 3 minutes and can move to a STACK or ProEst evaluation with a clearer picture of what you actually need.
Start with 3 free estimates. No credit card required. $199/month flat after that, unlimited estimators, no Autodesk dependency.
