TL;DR
"Estimating software" is three different products wearing one name, and most contractors buy the wrong one. If you price from a walkthrough and a phone call, Joist at $10 to $32 a month or Clear Estimates at $79 does the whole job. If you price from drawings, takeoff is the expensive part, and Buildxact at $199 a month with unlimited users is the quiet bargain against STACK's $249 per seat. If estimating is one module of a bigger job-costing problem, Contractor Foreman ($49 to $332), JobTread ($199 plus $20 a user) and Knowify ($99 to $329) are the platforms, and the per-seat math decides between them. Every price below was read off the vendor's live page in September 2026.
Most estimating software is bought after a bad month, when a job that looked like 35 percent margin closes at 12 and nobody can say where the other 23 went. The software rarely fixes that. What fixes it is knowing which of the three problems you actually have, because the tools for each one cost between $10 and $600 a month and the expensive one is often the wrong one.
Below is what each product costs, who each one fits, and the seat math that makes an all-in-one platform cheaper than a point tool at some crew sizes and pricier at others. Roofers have their own version of this decision, covered in our roofing estimating software breakdown, because satellite measurement changes the answer for that trade.
Three products share one name
The first product is a quoting tool. It turns a list of line items into a proposal the customer can sign on a phone, converts the signed estimate into an invoice, and takes the deposit. Joist is the clearest example. It does not know what drywall costs and does not want to.
The second is a cost-database estimator. It ships with thousands of pre-priced assemblies, updated on a schedule, so a remodeler can build a kitchen estimate from a template and adjust rather than start from a blank sheet. Clear Estimates and Buildxact live here, and so does Bolster's AutoCost.
The third is takeoff. If a set of plans arrives as a PDF and someone has to count doors, measure linear feet of base and square out the roof planes before anything gets priced, that counting is the job, and the software that does it on screen is priced per seat because it replaces hours of a paid estimator's time. STACK is the specialist. Buildxact bundles a version of it.
Then there are the platforms where estimating is one tab among ten. Contractor Foreman, JobTread and Knowify all estimate competently, but you are really buying scheduling, job costing, change orders and a client portal, and paying for seats accordingly.

| Verdict | Match the tool to where your numbers come from. Walkthrough: Joist or Clear Estimates. Drawings: Buildxact before STACK unless you bid daily. Office of five or more: run the seat math below. | |||
Cost database or your own numbers
The database is the feature that sells cost-based estimators, and it is worth understanding what you are getting. Clear Estimates advertises 13,000 pre-priced line items with quarterly rate updates. Bolster's Pro tier includes AutoCost. Contractor Foreman ships a local material database on every plan but only fills in the prices from Plus upward. Buildxact's Blu assistant builds assemblies for you on Foundation and generates whole estimates on Pro.
None of those numbers are your numbers. A regional database knows what a square of architectural shingles costs in your state on average. It does not know that your supplier gives you 8 percent off on volume, that your lead carpenter is $6 an hour above the regional median, or that your dump fees doubled in March. A database is a starting point that saves a blank page. It is not a margin guarantee, and treating it as one is how a 35 percent job closes at 12.
The practical test: if you already have a price book, even a spreadsheet, you need the quoting tool and not the database. If you have never written one down and your estimates live in your head, the database is worth $79 a month for the year it takes to build your own. Our markup versus margin explainer covers the arithmetic most estimators get wrong once the numbers are in.
Pro tip
Whichever tool you pick, export the line items you actually used on your last 20 jobs and compare them to what the database or your old sheet said. The gap on the ten most common items is your real estimating error, and it is usually two or three items doing most of the damage.
If you price from plans, takeoff is the expensive part
STACK's Takeoff & Estimate starts at $249 per user per month. For a commercial sub with two estimators bidding every day, $498 a month against two salaries is cheap. For a remodeler who gets a set of drawings four times a year, it is the most expensive software in the building.
That is why Buildxact's Foundation tier is the sleeper in this category. Digital takeoffs, unlimited users and dealer integration at $199 a month, or $169 on annual, undercuts a single STACK seat by $50 while covering the whole office. The takeoff tool is not as deep as STACK's, and a full-time estimator will notice. A remodeler doing occasional plan work will not.
Bolster puts its takeoff drawing tool on the $399 Pro tier with three users, which makes it the most expensive way to get takeoff on this list unless the options-and-upgrades proposal engine is the thing you are buying.
The estimate is only worth what the lead is
We build the site and search program that fills the estimate queue, then wire the request straight into whichever tool you pick.
When estimating is just one tab
For a shop with an office, a foreman and a bookkeeper, the question stops being "which estimator" and becomes "which platform," because the estimate has to become a budget, a schedule, a change order and an invoice without being retyped. Three platforms price that differently, and seat count decides.
Run the same office through all three. A two-person shop pays Contractor Foreman $105 on Standard, JobTread $219, and Knowify $128 on Core with one extra seat. At five people, Contractor Foreman Plus is $166 for up to eight seats, JobTread is $279, and Knowify has jumped to Advanced at $329 because Core only includes one user. At twelve, Contractor Foreman Pro is $221, JobTread is $399 and Knowify Advanced is $387 with two extra seats.
Contractor Foreman wins on price at every size, and their own comparison table is where the caveats live: Basic at $49 is one user, estimating starts on Standard, and the annual prices above become $132, $206, $282 and $415 if you pay quarterly. JobTread's argument is that every feature is on the one plan, implementation and training are free, and there is no tier you will outgrow. Knowify's is AIA pay applications, progress billing and the tightest QuickBooks job costing of the three, which matters to a commercial sub and to nobody else.
If your current tool is a field service platform rather than a construction one, check what you already own before adding any of these. Jobber, Housecall Pro and ServiceTitan all quote, sign and invoice from the truck, and the field service software roundup covers where each one stops. The contractor CRM breakdown covers the sales side, which is the half of estimating nobody prices.
The estimate is a sales document
Every vendor on this list will tell you their proposals close better, and one of them has the numbers to back it up: Bolster's whole pitch is that presenting options and upgrades inside the estimate lifts the average ticket. Joist's is that homeowner financing at the point of signature closes jobs that would otherwise stall at the price.
Both are true and neither requires their software. Three tiers on a proposal, a good-better-best on the parts of the job where the customer has a choice, and a way to sign and pay a deposit on a phone will do more for close rate than any cost database. Joist's Elite tier at $32 has change orders and e-sign, which is the cheapest way on this list to get all of that, and the change order template covers the one document that decides whether the extra work gets paid.
The faster half of the sale happens before the estimate exists. A quote that arrives the same day as the walkthrough beats a prettier one that arrives Thursday, and the lead follow-up system is where that speed comes from.
Three to skip
Takeoff seats for a business that gets drawings four times a year. At $249 a seat that is $2,988 a year to count doors on four jobs. Buildxact at $199 for the whole office, or an hour with a scale ruler, covers it.
Any platform's bottom tier if it excludes estimating. Contractor Foreman's $49 Basic is a real price for a real product, and the estimating module is not on it. Read the comparison table, not the headline.
A cost database as a substitute for a price book. The regional average is not your cost, and the day you stop checking it against your invoices is the day margin starts leaking. Buy the database to get started, then replace its numbers with yours one trade at a time.

Frequently asked questions
What is the best estimating software for a small contractor?
For an owner-operator quoting from a walkthrough, Joist at $12 to $32 a month covers estimates, e-signature, invoices and deposits. If you want pre-priced line items to build from, Clear Estimates at $79 a month adds a 13,000-item database with quarterly updates and no contract. Neither does takeoff from drawings, and neither needs to for most residential trades.
How much does contractor estimating software cost?
Between $12 and $600 a month depending on the type. Quoting tools run $12 to $32 (Joist), cost-database estimators $79 to $599 (Clear Estimates, Buildxact, Bolster), takeoff from $249 per user (STACK), and all-in-one platforms $49 to $399 with per-seat charges (Contractor Foreman, JobTread, Knowify). All figures read from the vendors' pricing pages in September 2026.
Do I need takeoff software?
Only if you regularly price from a set of plans. Takeoff software counts and measures on screen, and it is priced per seat because it replaces estimator hours. A remodeler who sees drawings a few times a year is better served by Buildxact's $199 Foundation tier, which includes digital takeoffs for unlimited users, than by a $249 STACK seat.
Is a cost database worth paying for?
As a starting point, yes. As a substitute for your own numbers, no. A regional database does not know your supplier pricing, your crew's wages or your local dump fees. Use it to avoid a blank page, then replace its figures with your actual costs from your last 20 jobs, one trade at a time.
Which is cheaper for a five-person office, Contractor Foreman, JobTread or Knowify?
Contractor Foreman, at $166 a month on the Plus tier with up to eight users on annual billing. JobTread is $279 ($199 plus four $20 seats) and Knowify is $329 on Advanced, because its $99 Core tier includes only one user. Contractor Foreman's price rises to $206 if you pay quarterly rather than annually.
Does Jobber or Housecall Pro count as estimating software?
For service trades, usually yes. Both quote, e-sign and invoice from a phone, which is what a plumber or HVAC company means by estimating. Neither has a cost database or takeoff, so a remodeler or builder pricing from plans needs one of the construction tools above. See the field service software roundup for where each platform's quoting stops.
