Estimating · Buyer’s guide

Construction estimating software in Australia,
thirteen tools compared for 2026.

A vendor-published comparison, written by a licensed builder who has priced and delivered over 200 homes. The criteria stated before any name, what each tool actually does rather than what it claims, and the four buyer profiles where we tell you to buy someone else.

01 / The short answer

Which construction estimating software to shortlist

For Australian residential builders the field is small. Buildxact suits sole traders and small builders who mainly need to quote. VIABUILD suits residential builders who want the estimate to become the budget. Buildsoft Cubit is the estimator’s tool and, with RIB CostX, one of two here reading CAD and BIM. CostMiner is the cheap, capable point tool; Built Simple the cheapest way in for a very small builder. Kreo and PlanSwift measure fast and stop there. Bluebeam Revu is markup, not estimating. ClickHome does not estimate at all, and Xero does not either, which the section below on Xero explains.

02 / The criteria

How each tool was judged

Eight tests, all checkable in a trial, and all of them things a feature list can claim without doing. Read these before the table, because they are what the table is scoring.

Takeoff from what you actually get sent

Most residential builders are sent PDFs, often scanned, sometimes photographed. Measuring a clean digital plan is the easy case. Ask what happens to a forty-sheet set, a drawing at an odd scale, and a revision that arrives mid-quote.

Assemblies you build and own

An assembly is a recipe: external wall per square metre carrying frame, sarking, cladding, insulation, fixings and labour in one line. They are what make the second job fast. Ask whether you can build and edit them yourself, and whether they leave with you.

Where the rates come from, and who keeps them current

A rate is a supply price, a supply-and-install rate or a subcontract package, and it has to be dated. The question that separates tools is whether actual invoice costs feed back into the library, or whether someone re-keys supplier price lists every quarter.

Prime cost items and provisional sums

PC and PS are how Australian residential contracts carry what is not yet decided, and they behave differently from a normal line. Ask to see one created, adjusted and reconciled. Software written for another market usually treats them as ordinary allowances.

GST from estimate through to claim

The tax treatment has to survive the whole chain, not just the estimate. Take a mixed-treatment line all the way to a progress claim and into the ledger, and watch what arrives. This is where products built around US sales tax reveal themselves.

Whether the estimate survives handover

An estimate that is exported into a budget is re-keyed, and re-keyed numbers drift. Ask to see an estimate become a job budget with cost codes intact, then a purchase order drawn against it. This is the single biggest structural difference between the tools here.

The path to your ledger

Xero or MYOB, one-way or two-way, and whether tracking categories are applied so cost lands against the job. A tool with a superb takeoff and no ledger path has moved your evening work rather than removed it.

Pricing, contract terms and what you take with you

Per user or per platform, monthly or a twelve-month minimum, and in which currency. Then the question people forget until it matters: if you leave, what happens to the cost library you spent two years building.

Every vendor statement on this page comes from that vendor’s own current public site, checked on 7 September 2026, with Built Simple, CostMiner and RIB CostX added and checked on 15 September 2026. Where a vendor documents nothing, the cell says so plainly rather than filling the gap with a guess, and “AI-powered estimating” on a home page is not treated as evidence of anything. Where we found no capability, the wording is “none named by the vendor at the time of writing”, which is not the same as saying none exists.

Cubicost (Glodon) was considered and left out. It is BIM quantity surveying for commercial and civil work, and we could not verify an Australian office or reseller, so including it would have meant guessing. The numbering below is a reading order grouped by what each tool actually is, not a ranking.

03 / The chain

From drawing to budget, in six steps

Worth two minutes before the comparison. Most of the difference between these tools is which of these six steps they cover and where they hand off.

Measure the drawings

Takeoff turns a plan into quantities: linear metres of wall, square metres of floor, counts of fixtures. On screen it replaces a scale rule and a highlighter, and the gain is not only speed. A measurement anchored to the drawing can be re-checked against it when a revision arrives, which a number typed into a spreadsheet cannot.

Turn quantities into priced work

Each quantity meets a rate, and a rate is either a supply price, a supply-and-install rate, or a subcontract package. This is the step where estimating software stops being a calculator and starts being a database, because the rate has to come from somewhere and be dated.

Group work into assemblies

An assembly is a recipe. External wall per square metre carries its frame, sarking, cladding, insulation, fixings and labour in one line. Assemblies are what make an estimate fast on the second job rather than the first, and their quality is the single biggest difference between a competent estimator and a quick one.

Handle what is not yet decided

Prime cost items and provisional sums carry the things the client has not chosen or the scope has not resolved. They are contractual instruments, not rounding, and they need to be visible as such to the client and reconcilable later. Watch how a tool creates and adjusts one before you trust it with a contract.

Add margin and produce the number

Overheads, margin and contingency go on, and the estimate becomes a price. Where margin is applied, per line or in total, changes what you can negotiate without re-pricing, so it is worth knowing which the tool does.

Hand the estimate over as a budget

The job is won and the estimate has to become the thing you control cost against. If that handover is an export, the numbers are re-keyed and they drift from day one. This step is invisible during a sales demo and it decides whether the estimate is worth anything six weeks later.

04 / The failure modes

Where estimates actually go wrong

None of these are software problems, which is why a feature comparison alone will not fix them. They are the reasons an estimate misses, and the reason to care which tool you pick is that a good one makes five of the six harder to do.

Pricing from memory, not a database

Rates recalled from the last similar job are already stale, and every estimator recalls them differently. Without a maintained database, each estimate is a fresh act of invention. No software fixes this on its own, because the database is yours to keep current.

Takeoff from the wrong revision

Quantities measured from a superseded drawing poison everything downstream, quietly, and you find out at frame stage. The takeoff has to be pinned to the current revision and re-checked when drawings move, which is the one thing on-screen measurement does that a spreadsheet cannot.

Allowances left vague

A prime cost item or provisional sum without a clear scope and number is a future argument. When the real quote lands above a vague allowance, the gap comes out of margin or out of the client relationship, and usually both.

No feedback loop from actuals

If close-out costs are never compared line by line against the estimate, the database never improves and the same misses repeat on every job. This is the single highest-value habit in estimating and the one most often skipped.

Two estimators, two answers

Without shared assemblies and costing rules, pricing consistency depends on who happened to do the takeoff. Clients notice when a variation is priced differently from the original, and so does the margin.

The system living in one head

When the process, the rates and the recipes exist only as one person’s experience, the business’s estimating capability resigns when they do. Getting it into software is worth more for this reason than for any hour it saves.

05 / Test it yourself

Six things to do in a free trial

Most of these tools give you a fortnight for nothing. This is how to spend an afternoon of it and learn more than any comparison table can tell you, including this one.

Use a job you already know the answer to

Not a sample file and not the job you are pricing this week. Take one you have finished, where the invoices are all in and you know what it truly cost. It is the only way to tell whether a tool is close, and it turns an opinion about software into a number.

Start the clock at signup, not after setup

Configuration is part of the product. A tool that needs a week of price-book work before it produces a number is telling you something a feature list will not, and that week is a real cost you will pay whether or not anyone counts it.

Throw your worst plan file at it

The forty-sheet set, the scanned one, the one at an odd scale. Vendor demonstrations run on clean drawings. Yours are not clean, and the difference between a tool that handles that and one that stalls is the difference between using it and abandoning it in month two.

Put a prime cost item and a provisional sum through it

Create one, adjust it, and reconcile it against an actual cost. These are Australian contractual instruments and software written for another market routinely treats them as ordinary allowances. Four minutes here tells you whether the product understands the contract you actually sign.

Revise a drawing halfway through

Issue yourself a revision mid-quote and see what happens to the quantities you already measured. A tool that flags what moved is worth real money. A tool that silently keeps the old numbers will cost you a job eventually, and you will not know which one.

Follow one GST-mixed line all the way to a claim

From the estimate, into the budget, onto a progress claim, and into your ledger. This is the chain where products built around US sales tax come apart, and it is the single most informative five minutes in the whole evaluation.

06 / Side by side

Thirteen tools, the same eight questions

Takeoff, assemblies, what the AI mechanically does, whether the estimate survives handover, accounting path, origin and published entry price. On a phone, scroll the table sideways.

07 / The field

The thirteen, one at a time

Grouped by what each tool actually is and alphabetical inside each group, not ranked. Who it genuinely suits, one honest limitation, and a plain verdict.

01 / Estimating inside a system that runs the job

Buildern

A builder whose pain is chasing subcontractors and updating clients as much as pricing work. External users, field workers, subcontractors, suppliers and clients, are unlimited and free, and you pay only for internal seats, which is the right pricing shape for that problem.

The honest limitation. Its AI is pointed at accounts payable, not at estimating, and assemblies are not documented anywhere public. It also prices in US dollars and does not start from Australian conventions, so prime cost items, provisional sums and GST across the estimate-to-claim chain are things you configure toward rather than things it assumes.

Verdict. Strong job management, unproven estimating depth for Australian residential work.

02 / Estimating inside a system that runs the job

Buildxact

The default answer for an Australian sole trader or small builder whose real problem is quoting. Estimating and takeoff are the core rather than an afterthought, job management sits on top, and unlimited users on every tier means putting the whole team in does not raise the bill.

The honest limitation. The AI is priced as add-ons rather than included, so the real monthly cost is the plan plus the assistants you actually need, and all of it sits in estimating. Once the job is won and the pain moves to supplier invoices, progress claims and cost control, the intelligence does not follow you there.

Verdict. The one to beat on estimating alone at the small end.

03 / Estimating inside a system that runs the job

Built Simple

A small builder, tradie or owner-builder who wants a shared job view, a tidier way to quote and a per-project profit figure without the weight of a full platform. It is priced by employees, up to five on Tradie and fifteen on Builder, and it starts at nothing, which is a genuinely low bar for a one-person outfit that has never run software.

The honest limitation. The estimating depth is the least documented on this page. A takeoff tool is named, but what it measures and from which files is not, assemblies are not described, and the vendor's pricing page names an AI without saying what it does. No accounting integration appears on the home or pricing page either, so treat the estimate-to-ledger path as a question for the trial, not a given.

Verdict. The cheapest way in for a very small builder; test the takeoff before trusting it.

04 / Relies on a third-party estimating engine

ClickHome

A volume or project home builder running 20 to 200-plus homes a year who already has an estimating engine and needs the workflow around it: sales, contracts, preconstruction, construction, finance and warranty.

The honest limitation. It is on this page to be ruled out, honestly. ClickHome documents no takeoff and no estimating of its own, and lists five construction ERPs under estimating and procurement. That tells you the shape of customer it expects: one whose estimating and ledger already live in a construction-specific system. If you are shopping for estimating software, this is not it.

Verdict. Not estimating software. Excellent volume workflow around someone else’s estimate.

05 / Estimating inside a system that runs the job

VIABUILD

We publish this page, so weigh this entry accordingly and make us sit the same test as everyone else. VIABUILD suits an Australian residential builder, project or custom, who wants the estimate to become the budget rather than be exported into one, and who would rather pay one platform price than run an estimating tool beside a management tool beside a ledger.

The honest limitation. Xero only, with no MYOB integration today. We are also early to market next to Databuild’s four decades and Buildsoft’s installed base among commercial estimators, and we sell to Australian residential builders specifically, so a commercial estimator or a civil contractor is genuinely better served elsewhere on this page.

Verdict. Built so the estimate survives handover. Narrower by design than a dedicated estimating tool.

06 / Estimating inside a system that runs the job

Wunderbuild

A builder running one or two jobs at a time who wants the whole team inside one system without per-seat pricing. Melbourne-built, priced by active project count rather than by seat, with unlimited users on every tier and no lock-in.

The honest limitation. The estimating story stops at price lists in the public documentation. Nothing we could find describes measuring quantities from a drawing, which is the half of estimating that costs you the evening. Establish that in the trial before anything else, because if takeoff is manual the cheap price is not the saving it looks like.

Verdict. Cheapest way into a connected system. Takeoff capability unproven.

07 / Dedicated estimating and takeoff

Buildsoft (Cubit)

The deepest takeoff on this page, and the right answer for an estimator who measures for a living. It is the only tool here that reads CAD and BIM as well as PDF, and the only one that will pull quantities straight off model elements. If you tender commercial work or price from consultant-issued models, this is a different class of tool from the residential products.

The honest limitation. It is estimating software, not a system that runs the job. The estimate leaves via an export or an integration rather than becoming the budget your POs draw against, and it is priced per user on a 12-month minimum, which is a different commitment shape from the flat monthly products here. For a builder pricing four houses a year, that is real money for capability aimed at someone else.

Verdict. The estimator’s tool. Overkill for a small residential builder, correct for a QS.

08 / Dedicated estimating and takeoff

CostMiner

A builder or estimator who wants spreadsheet-style estimating with a real digital takeoff attached and does not want to pay platform money for it. One plan, everything included, priced per user in Australian dollars with GST inside the figure, and a claims tracker bolted to the estimate, which most point tools leave out.

The honest limitation. It is an estimating tool with a claims tracker, not a system that runs the job. Purchase orders, committed cost and the budget the estimate should become are not documented, so the handover after the quote is a spreadsheet or an export. The vendor names no AI, which is an honest position rather than a gap if measurement is the job.

Verdict. Cheap, capable takeoff and estimating; the job still runs somewhere else.

09 / Dedicated estimating and takeoff

RIB CostX

A quantity surveyor, estimator or BIM manager measuring from consultant-issued models and drawings on commercial work. The live link between the takeoff and the workbook, so a revised drawing re-flows the quantities, is the feature the profession buys it for, and it is aimed at that profession rather than at a builder pricing houses.

The honest limitation. Everything about the commitment is a sales conversation: no price is published, the packages and licence types are named without figures, and there is no accounting integration, only an API. For a residential builder that is a large tool with a large onboarding for a problem a lighter product solves, and the estimate still has to be re-keyed into whatever runs the job.

Verdict. The QS’s tool. Quote-only, API-only, and aimed at a different desk.

10 / Dedicated estimating and takeoff

Databuild

An established Australian builder who wants estimating, job costing and accounting in one system rather than a construction product bolted to a separate ledger. Around forty years in Australian building offices, and the estimating database it carries is the reason people stay on it.

The honest limitation. It publishes no pricing and no trial, so it cannot be shortlisted from a desk. Its longevity cuts both ways too: years of estimating rates built up inside it carry real value and real switching cost, so ask the export question early. What leaves, in what format, if you go.

Verdict. Deep Australian estimating heritage. Opaque to evaluate before you talk to sales.

11 / Dedicated estimating and takeoff

Kreo

An estimator or quantity surveyor whose problem is that measuring a plan set takes two days, and who is content for job management, purchase orders and accounting to live elsewhere. As a point tool that is a legitimate answer rather than a compromise.

The honest limitation. It measures the drawing. It does not carry the job afterwards, and there is no Australian accounting integration named, with spreadsheets as the documented way data leaves. For an Australian builder that means takeoff gets faster and GST, purchase orders, claims and cost control stay exactly as manual as they were. It also prices in US dollars.

Verdict. Fast AI measurement, and nothing downstream of it.

12 / Takeoff only, no priced estimate

Bluebeam Revu

Someone who already lives in PDFs all day: marking up drawings, running revisions, issuing and reviewing documents, with measurement as one job among several. Its revision comparison is genuinely good and is a real reason to own it alongside an estimating tool rather than instead of one.

The honest limitation. It does not produce a priced estimate, and that is not a criticism of the product, it is the product. Measurements link out to Excel and are priced there, which means your rates, assemblies and margin logic live in a spreadsheet with everything that implies. If you are replacing a spreadsheet, this does not replace it.

Verdict. Excellent measurement and markup. Your estimate still lives in Excel.

13 / Dedicated estimating and takeoff

PlanSwift

A trade contractor or estimator who wants a mature, desktop-grade takeoff tool and is comfortable buying American software. It is long-established, widely used and covers general contracting plus the specialist trades.

The honest limitation. Nothing about it is built for Australian residential work. No GST handling, no prime cost or provisional sum conventions, no Australian accounting integration, and the price is in US dollars with the exchange rate as your problem. It is a good tool answering a question asked in another market.

Verdict. Capable takeoff, no Australian context at all.

08 / The migration

Moving off spreadsheets without breaking what works

The most common starting point, and the one most vendors handle badly. Your workbook is not the problem. The rates and assemblies inside it are the asset, and they are what has to survive.

Do not migrate the spreadsheet. Migrate the rates

The instinct is to recreate the workbook, tabs and all, inside the new tool. Resist it. What has value in that file is the rates and the assemblies you have refined over years, not the structure you built to work around a spreadsheet’s limits. Export the rate list first and treat the layout as disposable.

Start with your three most common job types

Not all of them. Build assemblies for the work you actually repeat, price one real past job with them, and compare the result against what that job truly cost. If the software lands within a couple of per cent of a job you know the answer to, your assemblies are right. If not, fix them before job four.

Run one live job in parallel

Price the next real job both ways, in the spreadsheet you trust and in the new tool. It doubles the work once. It also surfaces every missing rate and every assembly that does not match how you build, at a moment when the spreadsheet is still there to catch it.

Keep the spreadsheet until the second job closes

Not the second estimate, the second completed job. You do not know whether the new rates hold until actual invoices land against them. Cancelling the old method at go-live is how builders end up pricing from memory in month two.

Expect the first estimate to be slower

It will be, by a lot, and that is not a sign you chose wrong. You are building the library that the tool runs on. The honest curve is slower on job one, level on job two, and faster from job three, and any vendor promising a saving on the first estimate is selling.

Decide who owns the price book

A shared spreadsheet has no owner, which is why it rots. Name one person responsible for rates and assemblies, and set a cadence, quarterly is usually enough, for reviewing what actual costs are saying about them. This is the part that decides whether you are better off in two years.

09 / The decision

Which one should you choose

Five profiles, and we are the recommendation in exactly one of them. If that seems like an odd thing for us to publish, it is the only version of this page worth reading.

Volume or project home builder

Databuild or ClickHome with an estimating engine behind it, not us. At 50 or 200 homes a year the estimating database and the repeatable house type matter more than anything else here, and Databuild has forty years of that. Ask hard about the export path before you commit.

Boutique or custom residential builder

This is our segment and we will say so plainly: VIABUILD, because the estimate becoming the budget matters most when every job is different and margin is thin. Buildxact if estimating is genuinely the whole problem and you do not need the job run afterwards.

Small renovator or sole trader

Buildxact, not us. It is cheaper, it is built for exactly this, and unlimited users means the whole team fits. Wunderbuild if you run one or two jobs and price is the deciding factor, though establish whether it measures from drawings before you commit.

Commercial or civil contractor

Buildsoft Cubit, not us. It is the only tool here that reads CAD and BIM as well as PDF and pulls quantities off model elements, which is the job if you price from consultant-issued models. We do not serve this segment and would tell you so on a call.

Estimator working across several builders

Buildsoft Cubit or Kreo, not us. A per-user licence you carry between clients suits this shape of work, and neither ties you to one builder’s job management. Add Bluebeam Revu if drawing markup and revision comparison are a daily part of the job.

If you are torn, the tiebreaker is your own past job. Take one you have finished, where you know what it truly cost, and price it in the two tools you are weighing. The one that lands closest with the least fighting is the answer, and it takes an afternoon. The background is in what estimating actually involves, how takeoff works and what happens at handover. If AI across the whole workflow is also part of the decision, the AI construction software comparison covers a wider field.

10 / The Xero question

Can Xero do the estimating?

No, and it does not claim to. Xero's own construction page offers quotes you can brand and convert to invoices, and project time and expense tracking against a budget, on plans it publishes at $78, $107 and $143 a month after an introductory period, all including the GST and BAS tools a builder expects. What is not on that page is any way to measure a drawing, hold assemblies or produce a priced takeoff, because Xero is the ledger, not the estimating tool.

The useful arrangement is the one most Australian builders already run: keep Xero as the system of record for the accounts, and put the estimating in a tool that measures the plan and then pushes the resulting bills and claims across. Which tools do that, and in which direction, is the whole subject of construction software for Xero. Read on 15 September 2026; Xero's plans and prices change, so confirm them on its site.

11 / FAQ

Common questions.

Published entry prices here run from about $123 a month for a small Australian platform to $167 per user per month for a dedicated estimating tool on a twelve-month minimum. Takeoff-only tools start near US$35 per user. Two vendors publish nothing. Confirm current pricing with the vendor.

No, and a vendor promising it is selling something they have not built. AI can measure quantities from a drawing, apply your rates and flag what it could not resolve. The judgement calls, buildability, site conditions, what a subcontractor will actually charge, stay yours. That is the design, not a gap.

Set the scale, then measure lengths, areas and counts directly on the drawing rather than with a scale rule. The advantage over a spreadsheet is that each measurement stays anchored to the plan, so when a revision lands you can re-check it instead of re-measuring the whole set.

An estimate is your calculated cost, internal and adjustable. A quote is a fixed price offered to a client, which becomes binding on acceptance. A tender is a formal submission into a competitive process, usually against a defined scope and conditions. Confusing the first two is how builders give away margin.

Not on current evidence. It is removing the measuring, which is the slow, mechanical half of the job. What remains is judgement about buildability, risk, sequencing and what a price should be given who you are bidding against, and none of that is what these tools do.

As distinct contractual instruments, visible to the client and reconcilable when the actual cost lands, not as ordinary allowances buried in a total. Ask to see one created, adjusted and reconciled during a trial. Products written for other markets routinely get this wrong because the concept is Australian.

Not usually. Most tools here do both, and separating them means moving quantities between systems by hand. The exception is a dedicated markup tool like Bluebeam Revu alongside an estimating package, which is a common and reasonable pairing if drawing revisions are a daily part of your work.

Usually yes, but not for the reason vendors give. The gain is not speed on the first estimate, which will be slower. It is that rates, assemblies and actual costs stop living in a file nobody owns. Run one job in parallel before you switch, and keep the spreadsheet until the second job closes.
