Compare · Wunderbuild vs Buildxact
Wunderbuild vs Buildxact,
for a home builder.
Two Australian products a residential builder shortlists together, compared on each vendor’s own published material rather than on anybody’s ranking. What each entry plan really includes, how each one runs the job after the quote, and the conditions under which each is the better buy. We make competing software, which you should hold against everything below.
The short answer
Buildxact fits if takeoff and quoting are most of your week. On-screen takeoff with reusable measurements and recipes is the product’s centre of gravity, and it is the stronger of the two at it by a clear margin.
Wunderbuild fits if the jobs are already sold and the week goes on running them. Scheduling, selections, variations, invoicing and the accounting sync are in every tier, including the $123 one, where Buildxact starts them at Pro.
The comparison most builders get wrong. Buildxact’s Foundation plan at $199 a month excludes scheduling, invoicing, variations, selections, the client portal and the accounting sync, per the vendor’s own feature chart. The like-for-like against a Wunderbuild tier is usually Pro at $399, not Foundation.
Normalise the tax before you compare anything. Wunderbuild publishes prices including GST. Buildxact publishes prices excluding it. Comparing the headlines as printed flatters one of them by about ten per cent.

01 / The framing
Who each one is built for
These two get shortlisted together because they are both Australian, both sold to small and medium residential builders, and both publish a price, which is rarer in this category than it should be. They are not, however, the same shape of product, and the difference is not a feature list. It is where each one puts its centre of gravity.
Buildxact starts at the estimate. Its whole product radiates out from on-screen takeoff and a quote, and everything else is something you add on the way up the tiers. That is a coherent design, and for a builder whose problem is pricing work quickly and accurately it is the better design. The consequence is that the entry plan is not a job management subscription, and reading the pricing page quickly will not tell you that.
Wunderbuild starts at the job. It sells one feature set at every price point and bands the price by how many jobs you have running, so the cheapest tier does everything the dearest one does, for one project at a time. That is also coherent, and for a builder running two or three homes it is a very different value proposition from a tier ladder. The consequence is that the thing Buildxact is best at, measuring quantities off a drawing set, is not documented anywhere on Wunderbuild's site.
So the real question is not which product is better. It is which half of your week is the expensive half. Everything below is evidence for answering that, taken from what each vendor publishes about itself.
02 / The money
What each one costs, tier by tier
Each vendor's own published figures, in that vendor's own tax wording, read on 19 September 2026. Nothing here comes from a review site or an aggregator.
| Product | Entry plan | Top plan | What the tier is banded by | Users and terms |
|---|---|---|---|---|
| Wunderbuild | Starter, $123 a month. | Ultimate, $499 a month. Premium is $249 and Platinum $375. | Active projects. One on Starter, two to ten on Premium, eleven to twenty on Platinum, unlimited on Ultimate. | “Unlimited users” and “No lock in contract” on every tier. “All prices are in Australian Dollars (AUD) and include GST.” A free trial is offered; no duration is stated. |
| Buildxact | Foundation, $199 a month, or $169 a month billed annually at $2,030. | Master, $599 a month, or $509 billed annually at $6,110. Pro is $399, or $339 at $4,070. | Feature set. No project count appears on the pricing page. | “Unlimited Users” on every tier. “All Buildxact base plans and add-ons exclude and are subject to GST, where applicable.” Annual is a 15% discount on a 12-month commitment. “14 Day Free Trial”. |
Putting the two on the same tax basis
Wunderbuild states that its prices include GST. Buildxact states that its plans exclude it. Comparing $123 with $199 as printed is therefore comparing two different things, and the gap it shows is about ten per cent wider than the real one.
At the current 10% rate, Wunderbuild's four tiers work out at roughly $112, $226, $341 and $454 a month excluding GST. That arithmetic is ours rather than the vendor's, but the endpoints are confirmed by the vendor itself: its Xero App Store listing quotes the same plans as AUD $111.82 to $453.64 excluding tax. Against those, Buildxact's $199, $399 and $599 sit higher at every comparable point, which is worth knowing before you weigh anything else.
Then do the second adjustment, which matters more. Price each product at the tier that does the work you actually do, not at the entry price. The next section is what that adjustment looks like.
03 / The detail that decides it
What the entry plan actually includes
Buildxact publishes a tier-by-tier feature chart, so what its entry plan leaves out is the vendor's own statement, not our inference. Wunderbuild sells one feature set at every tier, so the same question has a different shape on each side.
| Capability | Wunderbuild, every tier from $123 | Buildxact Foundation, $199 | Buildxact Pro, $399 |
|---|---|---|---|
| Scheduling | Included. “Create project schedule” and “Allocate resources to tasks and milestones”. | Excluded. “Schedules” is marked as not in Foundation on the vendor’s own feature chart. | Included. |
| Purchase orders | Included. The features page names “Cost Purchase Order Receipts”, and purchase orders sync both ways with Xero per the App Store listing. | Included. “Purchase Orders” is the one workflow beyond estimating that Foundation carries. | Included. |
| Variations | Included. The pricing page lists “Manage variances” on every tier; the depth is not described. | Excluded. “Change Orders” is marked as not in Foundation. | Included. Variation approvals can be included with invoices, “highlighting changes from the old price to the new price”. |
| Customer invoicing | Included. “Customer invoicing”, and the Xero listing names progress claims among what it synchronises. | Excluded. “Invoicing” is marked as not in Foundation. | Included. Invoicing “using fixed, cost-plus or completion percent”, with up-front refundable deposits. |
| Accounting sync | Included. The home page names “built-in Xero, MYOB and QuickBooks integrations”. | Excluded. “Accounting Integrations” is marked as not in Foundation. | Included. Xero and QuickBooks named on the invoicing page; the help centre also covers MYOB AccountRight. |
| Client portal | Not named as a portal. The features page describes “Communication with the customer”. | Excluded. “Client Portal” is marked as not in Foundation. | Included. |
| Client selections | Included. “Selections” is listed on every tier. | Excluded. | Included. |
| Timesheets | Included. “Keep track of timesheets”. | Excluded. | Included. |
| Actual costings | Included. “Cost management” and “Financial reporting” on every tier. | Excluded. | Included. |
| Field app | A mobile app is named on the home page; its scope is not described. | Excluded. “Buildxact Onsite Mobile App” is marked as not in Foundation. | Included. |
| Takeoff | Not described. The tagline says “from take-off to final invoice”, and no measurement-from-drawings workflow is documented on the site. | Included. “Digital Takeoffs”, on-screen point-and-click, with measurements reusable across materials. | Included. |
| AI | None named anywhere on the site. | “Blu: Recipe Assistant” only. “Blu: Estimate Generator” is a $99 a month add-on. | “Blu: Estimate Generator” included. Takeoff Assistant is +$99 and Estimate Reviewer +$149 a month. |
Read that table once and the shortlist changes. A builder comparing $123 with $199 is comparing a platform against an estimating subscription. A builder comparing a Wunderbuild tier with Buildxact Pro at $399 is comparing two job management systems, one of which has a much stronger takeoff tool and the other of which does not step its price with your feature needs, only with your project count.
Neither model is wrong. Buying AI and job management deliberately, tier by tier, is a legitimate preference, and a builder who only quotes is well served by Foundation at a price no platform will match. But the arithmetic only works if you price the tier you will actually be on, and that is the step most comparisons skip.
04 / Dimension by dimension
The parts of the job you are really weighing
Estimating, scheduling, orders, supplier bills, variations, claims, the client, the ledger, the AI and the API. Where a vendor does not document something, this table says so rather than asserting that the product cannot do it.
| What you are weighing | Wunderbuild | Buildxact |
|---|---|---|
| The shape of it | A management platform sold as one feature set. “Construction Management Software for Australian and New Zealand Builders”, “from take-off to final invoice”, pitched at “every home builder”. | An estimating-led tool that widens as you pay more. The takeoff-to-quote workflow is on every tier; job management, schedules and the accounting sync start at Pro. |
| Estimating | “Unlimited estimations” on every tier, built on price lists. Measurement off a drawing set is never described, so if you take off from PDFs, this is the first thing to test rather than assume. | The core of the product. On-screen takeoff, point and click, with measurements reusable across materials, plus recipes for assemblies. This is the strongest thing either product does. |
| Scheduling | On every tier. Tasks, milestones and resource allocation are named; dependency types and baselines are not described. | Pro and above. Gantt charts with colour coding, an editable critical path, bulk email to assigned subcontractors, and task reminders. Dependency types and baselines are not named on the scheduling page. |
| Supplier invoices | Purchase order receipts are named on the features page, and expenses sync to Xero. Automated capture and coding of a supplier bill is not described. | Xero bills can be brought back into Buildxact’s Imported Bills feature if that direction is chosen at setup. Automated capture and coding of a supplier bill is not described. |
| Progress claims | Progress claims are named in the vendor’s Xero App Store listing as one of the things the integration synchronises. Contract build stages and claim schedules are not described on the site. | The word “progress claim” does not appear on the invoicing page. The equivalent is invoicing on “completion percent”, with variation approvals carried into the invoice. |
| Client portal | Customer communication is a named part of the product. A separate client-facing portal is not described. | A client portal and online client selections are named, from Pro upward. |
| Xero, and which way | Both ways on invoices, contacts, quotes, tracking categories and purchase orders, per the App Store listing, with accounts and credit notes listed as one-directional. MYOB and QuickBooks are named on the home page without object detail. | You choose the direction at setup. Received purchase orders become Xero bills and invoiced jobs become sales; Xero bills can come back as imported bills. Up to two tracking categories, “for example, Job ID and Actual Costing Category”. Also MYOB AccountRight and QuickBooks Online. |
| AI | Nothing named. The only AI material on the site is a May 2026 article about the industry rather than a capability of the product. | Blu, sold by the assistant: Recipe Assistant on Foundation, Estimate Generator from Pro, Takeoff Assistant and Estimate Reviewer on Master, each also available as a monthly add-on. |
| API and AI agents | No public API, webhooks or agent connector found on the vendor’s site. That is what we looked for and did not find, not a statement that none exists. | A public API and signed webhooks with developer documentation at developer.buildxact.com. Some webhook events are limited to Merchant and Manufacturer plans. No vendor MCP connector found. |
| Where it is from | Melbourne. The site gives a Collins Street address and sells to Australian and New Zealand builders. Where the data is hosted is not stated. | Australian-founded, selling into Australia, New Zealand, the United Kingdom, the United States and Canada. Where the data is hosted is not stated. |
| Trying it | A free trial is offered. No duration is published, so ask for one long enough to run a real job. | “14 Day Free Trial”. Training and support are listed as included on every tier; priority support is Master only. |
Sources, all read on 19 September 2026: the Wunderbuild home, features and pricing pages and its Xero App Store listing; the Buildxact Australian pricing, features, scheduling and invoicing pages, its Xero help-centre article and its developer documentation. Where a capability is not named in those pages, this page records that we could not find it, which is a statement about the documentation and not about the product. Both vendors change products and prices without notice.
05 / The decision
Where each one is the stronger choice
A comparison that cannot name the conditions under which each product wins is not a comparison. Here are ours, and we have no stake in either answer.
Buildxact is the stronger choice when
- Takeoff is the work. If you price a lot and build a little, a tool built around on-screen measurement with reusable quantities and recipes will beat a broader platform that does not describe measuring from drawings at all. Renovation builders, trades who quote heavily and anyone tendering more than they win sit here.
- You want to buy capability in steps. The tier ladder lets you start at $199 with estimating and orders and add job management and AI when you need them, rather than paying for a platform from month one. If cash is tight and quoting is the bottleneck, that is a real advantage.
- You want the AI itemised. Blu is sold per assistant, each priced, each optional. You can take the Recipe Assistant and skip the rest, or take none of it. For a builder who wants to know exactly what the AI costs and what it does, that is a more honest shape than a platform price with intelligence folded into it.
- Your bookkeeper wants the sync documented. Buildxact's help centre spells out direction, objects, triggers and tracking categories. That level of detail is unusual in this category and it saves an argument later.
Wunderbuild is the stronger choice when
- The jobs are already sold. If your week is running two or three homes rather than pricing ten, everything you need is in the entry tier. Getting scheduling, selections, variations, invoicing and the accounting sync at $123 a month including GST is a genuinely low price for that scope.
- Your office is large. Unlimited users on every tier, with the price banded by active projects rather than headcount, means adding an estimator, a contracts administrator and two supervisors costs nothing. Buildxact also offers unlimited users, so this is only decisive alongside the tier point above.
- You do not want a tier ladder. One feature set at every price is simpler to reason about, and it means a capability you did not know you needed is already there when you reach for it rather than an upgrade conversation.
- You have no appetite for AI. Nothing on Wunderbuild's site names an AI feature, so nothing in the price is paying for one. Some builders want software that does exactly what it is told, and that is a position rather than a failure of nerve.
If both descriptions half fit, which is common, the deciding evidence is cheap. Both offer a trial. Run the same real job through each: take off one plan set, raise one purchase order, process one supplier invoice, approve one variation and raise one claim. Count the keystrokes and the places a number gets typed twice. On products this differently shaped, that count is the comparison.
06 / Before you sign
Questions to put to both vendors
Worded so the same question works on either call, and so a confident answer and a hedge are easy to tell apart. Take the answers in writing.
- 01
Which tier am I actually buying?
This is the first question and most builders skip it. Price one product at the tier that carries the features you need, not at the headline. On Buildxact that usually means Pro rather than Foundation, because scheduling, invoicing, variations, selections, the client portal, the field app and the accounting sync all start there. On Wunderbuild it means counting the active projects you will have at your busiest, not today, because that is what moves you up a band.
- 02
Show me a takeoff off my own worst plan set.
Not the demonstration drawings. Your messiest recent job, ideally the one with the revised set. Buildxact documents on-screen takeoff and its whole product is built around it, so make it prove speed on forty sheets rather than four. Wunderbuild does not describe measurement from drawings anywhere we could find, so ask directly how quantities get into an estimate and whether anyone is measuring by hand.
- 03
Run one supplier bill end to end, in front of me.
Neither vendor documents automated capture and coding of a supplier invoice, so assume it is manual on both until someone shows you otherwise. What you are measuring is how many screens and how many keystrokes it takes from paper invoice to coded cost on the job to a bill in your ledger. Do it with a real invoice that has a part delivery on it, because that is where the process usually falls over.
- 04
Raise a claim with an approved variation in it.
The single most residential-specific workflow, and the one most likely to be thinner than it looks. Ask to see a claim built against contract build stages, with a variation approved after the contract was signed carried into it, and the retention treatment if you hold any. Ask what the client sees and how they approve it.
- 05
Push a bill and an invoice to my actual Xero file.
A demonstration organisation proves nothing. Watch a real bill and a real customer invoice land in your own ledger and check that the job coding survived the trip. On Buildxact, confirm which direction you chose at setup and whether two tracking categories cover how your bookkeeper reports. On Wunderbuild, confirm the object list in the App Store listing against what you actually need, because it is more specific than the marketing pages.
- 06
What happens to my data if I leave?
Ask it in writing, of both, before you sign anything. What exports, in what format, and does it include the price book, the assemblies, the job history, the approvals and the documents. Years of rates are usually the most valuable thing in the system and the least portable, and the answer is much harder to get after you are a customer.
07 / Declared interest
A third option, and our cards on the table
We publish this page and we make competing software, so this section is the part to read sceptically. Nothing above changes if you skip it, and for a lot of builders the right answer genuinely is one of the two products already covered.
VIABUILD is the Construction Operating System for Australian residential builders. The category difference is that it is one system on one data model rather than a set of modules: the estimate becomes the job budget, and purchase orders are raised from its lines. Upload a supplier invoice and Oryn reads it and fills in the lines for you to check against the purchase order and approve. It connects to Xero, which stays your accounting system. Our pricing is published on the pricing page and is a flat platform price rather than a tier ladder or a project band.
- Business plan at $555 a month, the whole platform, with three users included and additional users at $65 a month each.
- Annual at $5,994, a 10% saving against monthly, on a twelve-month non-refundable commitment.
- Self-serve entry is seven days free, then a first month at $299.
- All figures in Australian dollars and inclusive of GST. The monthly plan has no lock-in.
What we will not claim. We are newer to market than both products on this page and we have a smaller Australian user base than either. We build for residential specifically, so a commercial head contractor or a civil operation is better served elsewhere. We do not publish a takeoff comparison against Buildxact, because takeoff is what Buildxact is built around and we would rather you tested that yourself than took our word for it. And we have no data importer for either product today, so a move means exporting and mapping rather than a button.
If you want us in the comparison properly, the head-to-head pages do it dimension by dimension, with the same evidence discipline as this page: VIABUILD vs Wunderbuild and VIABUILD vs Buildxact. If you are leaving one product rather than choosing between two, the Buildxact alternatives roundup sorts the whole field into categories, most of which are not us. And the software evaluation checklist is deliberately vendor-neutral: use it on all three of us.
08 / FAQ
Common questions.
It depends entirely on which tier you need, and the headlines are not comparable as printed. Wunderbuild states that its prices include GST; Buildxact states that its plans exclude GST. Put both on the same basis first. Wunderbuild’s four tiers run $123, $249, $375 and $499 a month including GST, which at the current 10% rate is roughly $112, $226, $341 and $454 excluding it, and the vendor’s own Xero App Store listing quotes the same range as AUD $111.82 to $453.64 excluding tax. Buildxact runs $199, $399 and $599 a month excluding GST, or $169, $339 and $509 on a twelve-month commitment. Then price the tier you would actually be on: Buildxact’s Foundation plan excludes scheduling, invoicing, variations and the accounting sync, so a builder who needs those is comparing Pro at $399 against a Wunderbuild band set by active project count. Both vendors publish these figures on their own sites and both can change them, so confirm before you decide.
Neither is better in the abstract, and the honest split is by what your week looks like. If most of your week is takeoff and quoting, Buildxact is the stronger product: on-screen takeoff with reusable measurements and recipes is the thing it is built around, and nothing on Wunderbuild’s site describes measuring off a drawing set at all. If most of your week is running two or three homes that are already sold, Wunderbuild sells you scheduling, selections, variations, invoicing and the accounting sync in its entry tier, where Buildxact starts those at Pro. The cheapest way to settle it is to write down the five things you did most last month and price each product at the tier that does all five.
No. Buildxact publishes a tier-by-tier feature chart on its Australian pricing page, and when we read it on 19 September 2026 it marked Schedules as not included on Foundation, along with Selections, Change Orders, Timesheets, Actual Costings, Invoicing, Accounting Integrations, the Client Portal, Request for Quotes and the Onsite mobile app. Foundation carries lead management, digital takeoffs, estimate costings, the Blu Recipe Assistant, quote letters, digital signatures, supplier integration, purchase orders and support. That makes Foundation an estimating and quoting subscription rather than a job management one, which is a reasonable thing for it to be, but it changes which Buildxact plan belongs in a comparison against a platform sold as one feature set.
Both name Xero, MYOB and QuickBooks. The detail differs in where it is documented and how specific it is. Buildxact’s help centre describes the Xero connection in unusual detail: you choose the direction at setup, received purchase orders become bills in Xero, invoiced jobs become sales, Xero bills can come back as imported bills, contacts sync both ways, and up to two tracking categories are applied, for example a job ID and a costing category. Wunderbuild names Xero, MYOB and QuickBooks on its home page without object detail, and the specifics sit in its Xero App Store listing instead: invoices, contacts, quotes, tracking categories and purchase orders both ways, with accounts and credit notes listed as one-directional. Xero requires apps to declare what they read and write, so that listing is usually more precise than a marketing page, which is a useful habit when you are checking anyone.
Carefully, and this is worth a specific demonstration rather than a yes. Buildxact does not use the phrase “progress claim” on its invoicing page; what it documents is invoicing on a completion percentage, with variation approvals carried into the invoice and refundable deposits credited against future invoices, which is the same job by a different name. Wunderbuild does not describe claims on its own pages either, though progress claims are named in its Xero App Store listing as one of the things the integration synchronises. For an Australian residential builder on a fixed-price contract, the questions that actually matter are whether a claim can be built against contract build stages, whether a variation approved after signing is carried in, and what the client sees. Ask both to show you one, on a contract that looks like yours.
Buildxact does, and sells it by the assistant. Blu Recipe Assistant is on Foundation, the Estimate Generator comes with Pro or as a $99 a month add-on, and the Takeoff Assistant and Estimate Reviewer come with Master or as add-ons at $99 and $149 a month. That is a deliberate model: you can buy the parts you want or none of them. Wunderbuild names no AI feature anywhere on its site, and the only AI material we found was an article about the industry rather than a capability of the product. Absence of documentation is not proof of absence, so ask the vendor directly if it matters to you. On both, the question worth asking is not whether there is AI but what it does to a number you are going to send a client, and whether a person confirms it before it goes.
