Best Concrete Estimating Apps and Software for Contractors in 2026

Every concrete contractor eventually asks the same question: is the estimating I do on a legal pad costing me work? The honest answer depends on what you bid. A commercial sub reading 80-page structural sets needs something very different from a turnkey residential outfit pricing a driveway on Tuesday and a house pad on Wednesday. Below is an honest read on the main options in 2026, including ours, and who each one actually fits.

Prices listed are what the vendors published at the time of writing. Check them before you buy, because they move.

The short version

If you bid commercial work off PDF plan sets, you want dedicated takeoff software and you should expect to pay four figures a year for it. If you bid residential and light commercial and your real bottleneck is turning a site visit into a proposal, you want a phone-first estimating app and you should not be paying four figures for it. If your bottleneck is finding customers at all, you are looking at a CRM, not an estimating tool, and you should be clear with yourself about which problem you are solving.

Plan takeoff software: STACK and PlanSwift

These are the two names that come up most for contractors working from drawings.

STACK is cloud based, so it runs in a browser on any machine and your takeoffs live on their servers rather than one computer. It has concrete-specific conditions, so you can set up a footing or a slab once and reuse it. There is a free tier, a Build & Operate plan around $599 a year, and the full Takeoff & Estimate plan around $2,599 a year. That top plan is the one with the estimating engine, and it is priced per user.

PlanSwift is the desktop veteran, around $2,000 a year, and it is Windows only. Mac users run it through Parallels or Boot Camp or not at all. It is a point-and-click takeoff tool: you load a plan, click your areas and lengths, and it feeds quantities out to Excel. It is capable and a lot of estimators have a decade of muscle memory in it. Reviewers consistently flag two things — the interface feels dated, and support can be slow.

Both are the right answer if the job starts with a PDF. Neither is something you open standing on a driveway.

All-in-one business platforms: Houzz Pro and QuoteIQ

Houzz Pro starts around $399 a month and is really a business platform with estimating attached — lead generation, CRM, client portal, 3D design tools, invoicing. It is built for interior designers, remodelers and design-build firms. If you are a concrete sub whose leads come from three general contractors you have worked with for years, you are paying for a lead engine you do not need.

QuoteIQ is mobile and web, with plans published from around $29.99 a month up to several hundred, covering estimating plus CRM, scheduling, invoicing and payments. It is aimed broadly at home-service and trade contractors rather than concrete specifically, which is the trade-off: wider coverage, less depth on the concrete math.

The question to ask about any all-in-one is whether you will actually use the other eight modules. If you will, the price makes sense. If you bought it for the estimating and ignore the rest, you overpaid.

Spreadsheets

Most concrete contractors are still estimating in Excel, and it deserves a fair hearing. A spreadsheet you built yourself fits your work exactly, costs nothing, and you already know where everything is. That is not nothing.

What it does not do is travel. The formulas live on one machine, usually one person's machine. Nobody else in the company can safely touch them. A tab gets copied for a new job, someone overwrites a formula with a typed number, and six months later two jobs that should price the same do not. And you cannot run it standing on a site with a GC waiting on a number.

If your spreadsheet is working and it stays on your desk, keep it. If you have ever been burned by a broken formula or needed a number while you were away from the office, that is the actual case for moving.

Concrete-specific phone estimating: Cornerstone Bids

This one is ours, so read it with that in mind.

Cornerstone Bids is built for one trade — turnkey concrete and masonry — and for one moment: you are standing on the job with dimensions in front of you and you want a real number before you drive away. It has a separate calculator per phase: footings, stem walls, slab, block walls, concrete walls, columns, stairs and tie beams. Each one takes dimensions and returns quantities with the details estimators actually argue about built in — rebar lap factors, corner bars and dowel hooks, block counts split from grout so filled cells and bond beams do not get counted twice, ladder wire by course, waste factors you set yourself.

From there it builds a cost summary split across material, labor, equipment and subcontract, applies your markup, and produces a PDF proposal you can send from the truck. You set your unit pricing once and it carries to every project.

What it does not do: it does not read PDF plans. You enter dimensions; it does not measure a drawing for you. If your workflow starts with a plan set rather than a tape measure, STACK or PlanSwift is the honest answer, not this. It also only covers concrete and masonry — there is no framing, electrical or plumbing in it, on purpose.

It runs on iPhone, Android and the web, and it is free to try at cornerstonebids.com.

How to pick

Answer these three in order.

Where does a job start for you? If it starts with a PDF plan set, buy takeoff software and stop reading price comparisons — the time it saves pays for it. If it starts with a site visit and a tape, a phone app will serve you better and cost a fraction.

What is your actual bottleneck? Doing the math, or getting the proposal out? Most residential concrete contractors are slow at the second one, not the first. They can price a slab in their head; what takes three days is sitting down to write it up. Buy for the bottleneck.

Will you use the rest of it? All-in-one platforms are good value when you run the whole business through them and expensive when you use one module. Be honest about which you are.

A note on accuracy

No estimating app is more accurate than the numbers you feed it. Every tool here will happily return a confident total built on a ready mix price from two years ago or a labor rate you have never hit. The accuracy comes from keeping your unit pricing current and from carrying your waste factors consistently job to job, so that when a pour goes badly you can go back and find out where the estimate and the field parted ways. The software's job is to do the arithmetic without mistakes and to keep the assumptions in one place. The judgment is still yours.
