STACK is the cloud-based contractor bidding software built for estimators who price work off digital plan sets rather than from a jobsite walkthrough. Specifically, the platform handles on-screen takeoff (area, linear, and count measurements), assembly takeoff, integrated cost data, and proposal generation, all in the browser so a team can collaborate on the same project. Per the public pricing page at stackct.com, Premium opens at $249 per user per month and Pro at $299 per user per month, both billed annually.

In practice, STACK shines for commercial subs and general contractors who bid from blueprints and want measurements, cost data, and proposals in one connected tool. Furthermore, the cloud model means estimates are not trapped on a single desktop, which matters for teams. By contrast to a quick field quoter, STACK is built around the plan-reading half of bidding.

The honest tradeoff: the per-user price sits well above a mobile quoting app, the learning curve is real for a solo contractor, and it is overkill for shops that bid mostly from site visits. Ultimately, for estimators and teams who live in blueprint takeoff and want a transparent, posted per-user price, STACK is the most-cited cloud takeoff and bidding tool in 2026. Notably, STACK also offers a free version and a 7-day Pro trial to test before paying.

Buildxact is the contractor bidding software built around the residential builder’s full bid flow: measure the plans, build the estimate, and send a professional quote without re-keying numbers between tools. Specifically, per the public pricing page at buildxact.com, the Go plan is free with limited credits, Foundation opens at $169 per month on annual billing ($199 monthly), Pro at $339 per month annual, and Master at $509 per month annual.

In practice, the platform connects on-screen takeoff to a live estimate and a client-ready quote, with templates and assemblies that speed up repeat bid types. Furthermore, the free Go plan and a 14-day trial let a builder test the flow before committing. By contrast to STACK, Buildxact leans residential and quoting rather than commercial estimator workflows.

The honest tradeoff: the per-month price climbs quickly past the entry tier, the depth is aimed at residential building rather than service-trade dispatch, and very small shops may not need the full takeoff engine. Ultimately, for residential builders and remodelers who want takeoff, estimate, and quote stitched into one transparent, posted-price platform, Buildxact is one of the most balanced bidding tools on this list.

Contractor Foreman is the contractor bidding software for small general contractors who want estimating and bidding bundled with full project management without paying enterprise rates. Specifically, per the public pricing page at contractorforeman.com, Basic opens at $49 per month, Standard at $105 per month, Plus at $166 per month, Pro at $221 per month, and Unlimited at $332 per month, each with a 30-day free trial.

In practice, the platform covers estimates and bids alongside invoicing, time cards, daily logs, change orders, and a client portal as you climb tiers. Furthermore, the low Basic entry point makes it one of the cheapest ways to get bidding and project management under one login. By contrast to a focused takeoff engine, Contractor Foreman trades takeoff depth for breadth of features.

The honest tradeoff: the interface packs a lot in and can feel busy, on-screen plan takeoff is lighter than STACK or PlanSwift, and some bidding features sit in higher tiers. Ultimately, for small GCs who want one low-cost platform that handles bidding plus the job after it is won, Contractor Foreman is the strongest all-in-one value on this ranking.

Jobber is the cleanest contractor bidding software landing spot for service-trade contractors who bid quick jobs and want the quote to flow straight into scheduling, invoicing, and payments. Specifically, per the public pricing page at getjobber.com, Core opens at $29 per month on annual billing, Connect at $99 per month annual, and Grow at $149 per month annual.

Notably, the transparent posted pricing is a relief after the gated quote process at the enterprise tools: contractors can see exactly what they are paying before signing up. Furthermore, Jobber covers quoting, online booking, client texting, scheduling, dispatching, integrated payments, and invoicing in one workflow. By contrast to a takeoff engine, Jobber is built for fast service-job quotes rather than blueprint estimating.

The honest tradeoff: no plan-based digital takeoff, and the Core tier is light on bid-specific depth and capped at one user. Ultimately, for HVAC, plumbing, electrical, landscaping, and field-service contractors who want a transparent, published-price tool that turns quick bids into booked, invoiced work, Jobber is a strong fit on this ranking.

Joist is the contractor bidding software for solo trades who want the simplest possible path from a quick estimate to a sent invoice on a phone. Specifically, per the public pricing page at joist.com, Joist no longer offers a free plan: Basics opens at $10 per month and is capped at 5 documents per month, Pro is $16 per month with unlimited documents, and Elite is $32 per month with business reports and change orders. A 14-day trial of the paid features is available after signing up.

In practice, Joist is genuinely fast for a one-person crew: build a basic estimate, send it, collect payment, and convert it to an invoice. Furthermore, online payments and homeowner financing are built in even at the Basics tier. By contrast to Jobber or Contractor Foreman, Joist is deliberately lightweight, with no scheduling, dispatch, or plan takeoff.

The honest tradeoff: the Basics 5-documents-per-month cap is tight for a busy bidder, there is no plan-based takeoff, and the feature set tops out well below the platform tools on this list. Ultimately, for solo trades who bid a handful of simple jobs a month and want the cheapest, simplest quote-and-invoice app, Joist is a clean fit, with the caveat that the former free tier is gone.

PlanSwift is the long-standing desktop contractor bidding software for estimators who do point-and-click on-screen takeoff and then build priced bids in Excel. Specifically, estimators click directly on digitized blueprints to pull quantities for materials and labor, then push those numbers into estimating templates. PlanSwift is sold as a desktop license rather than a monthly subscription; confirm current pricing with the vendor before buying, since the figure and license terms are not posted on a clean public per-month page.

In practice, PlanSwift is fast and familiar for estimators who prefer a desktop tool and tight Excel integration for concrete, drywall, electrical, and similar trades. Furthermore, the point-and-click takeoff is genuinely quick once configured. By contrast to STACK, PlanSwift is desktop-bound rather than cloud-collaborative.

The honest tradeoff: it is a desktop product (less suited to cloud teams), pricing is not transparently posted per month, and the interface shows its age next to newer cloud tools. Ultimately, for desktop estimators who want proven on-screen takeoff with Excel at the center of their bidding, PlanSwift remains a credible pick, with the caveat that you should confirm current pricing with the vendor.

Houzz Pro is the contractor bidding software aimed at residential remodelers and designers who win work on the polish of the proposal. Specifically, the platform lets contractors build branded estimates, proposals, and invoices, store unlimited documents, save templates, and present work with 3D floor-planning tools. Per houzz.com, Houzz Pro no longer posts a fixed monthly price: paid plans are volume-based by annual project volume (Pro, Custom, Enterprise), with a free plan and a 30-day trial to start.

In practice, the proposal and presentation tools are the draw: a remodeler can turn an estimate into a polished, client-facing proposal that helps close higher-end residential work. Furthermore, the included lead and project tools tie the bid to the rest of the homeowner relationship. By contrast to a pure takeoff engine, Houzz Pro leans on presentation and homeowner experience.

The honest tradeoff: the move to volume-based pricing makes the real cost hard to compare up front, the platform is residential-and-design-focused rather than commercial, and takeoff depth trails dedicated estimating tools. Ultimately, for residential remodelers and designers who bid on presentation quality and want branded proposals plus 3D tools, Houzz Pro is a strong fit, with the caveat that you should request a current quote since pricing is volume-based.

PlanHub is the contractor bidding software for the sourcing side of bidding: it is a marketplace where general contractors post projects and invite subcontractors, and where subs find work to bid on. Specifically, per planhub.com, general contractors get free access to post projects, share files, and collect and evaluate bids, while subcontractor plans are gated and tiered (third-party reporting puts paid sub tiers in a roughly $1,999-and-up annual range based on trade and coverage). A free trial is offered.

In practice, PlanHub solves a different problem than an estimating tool: it is about finding bid opportunities and managing invitations, not measuring quantities. Furthermore, the free GC side makes it easy for a general contractor to broadcast a project to many subs at once. By contrast to STACK or Buildxact, PlanHub does not build your priced estimate; it brings you the jobs to bid.

The honest tradeoff: subcontractor pricing is gated and can run into the thousands per year, the value depends on deal flow in your trade and region, and you still need a separate tool to actually build the bid. Ultimately, for subs who want a steady stream of bid invitations and GCs who want to source coverage, PlanHub is the most-cited sourcing marketplace on this list, paired with an estimating tool to price the work.

ConstructConnect is the contractor bidding software for commercial project sourcing and bid management at scale. Specifically, the platform gives subs and GCs a searchable database of commercial projects out to bid, plus tools to create and send bid invitations, prequalify subcontractors, and track bid coverage across a network of construction professionals across North America.

In practice, ConstructConnect is about pipeline: finding the right commercial projects to pursue and managing the invitation-and-coverage process around them. Furthermore, the prequalification and coverage tools help GCs make sure every trade on a bid has enough sub interest. By contrast to a takeoff engine, ConstructConnect feeds the front of the funnel rather than building the priced estimate.

The honest tradeoff: pricing is not publicly disclosed at audit time and is gated behind a sales-quote process with an annual commitment, the platform is squarely aimed at commercial work rather than residential, and it is overkill for a contractor who bids only local jobs. Ultimately, for subs and GCs who pursue commercial projects and need a real lead database plus bid management, ConstructConnect is the most-cited commercial sourcing platform, paired with an estimating tool to price each bid.

Procore is the contractor bidding software choice for enterprise general contractors and construction management firms that run formal bid pursuit on large projects. Specifically, the platform pairs Bid Management and Procore Estimating with full construction project management, so a pursued project flows from bid invitation through estimate into the live job inside one system.

In practice, the bid management module is a structured pipeline for project pursuit, bid invitation tracking, and coverage, while estimating ties quantities and costs to the same project record. Furthermore, the construction PM depth around it is unmatched for large, multi-stakeholder jobs. By contrast to a focused estimating tool, Procore targets a fundamentally larger contractor scale.

The honest tradeoff: pricing is not publicly disclosed at audit time and is scoped to annual construction volume behind a sales quote, the platform is significant overkill and budget for SMB and solo contractors, and the bidding tools assume an enterprise pursuit process. Ultimately, for enterprise GCs and CM firms with formal bid pursuit and multi-million-dollar pipelines, Procore is the contractor bidding software at the top of the enterprise tier.

Buildertrend is the contractor bidding software for established residential builders and remodelers who want the proposal that wins the job to flow straight into the platform that runs the build. Specifically, the platform offers proposal and bid tools on the front end (lead capture, estimates, client-facing proposals and selections) that connect directly into post-sale project management (scheduling, daily logs, change orders, client portal).

In practice, this bid-to-build coverage is what residential builders pay for: the same platform that sent the proposal also runs the job. Furthermore, the selections and client-portal tools help homeowners approve finishes during the proposal stage. By contrast to a standalone estimating tool, Buildertrend bundles bidding into a much larger system.

The honest tradeoff: Buildertrend moved to volume-based custom quotes and no longer posts fixed monthly pricing publicly (third-party reporting puts the entry tier in the several-hundred-per-month range), the platform is overkill for solo contractors, and the bidding tools are a feature of a PM platform rather than a focused estimator. Ultimately, for established residential builders who want proposals and full project management in one system, Buildertrend is the most-cited bid-to-build platform, with the caveat that you should request a current quote since pricing is volume-based.
