Line-by-line bill of quantities, market price comparison, and a risk audit of the fixed-price contract you're about to sign. Built for Australian homeowners. Reviewed and signed by a human.
A single rate table goes stale within months. Construction costs move 5% a year, and they don't move evenly across states. We triangulate every line item against eight independent sources of current Australian construction cost data, refresh them on documented schedules, and tell you on the cover page how fresh each input is.
Series 6427.0 Table 17 — residential construction output, by state. The authoritative cost-movement signal.
Real cost-of-works estimates on every DA lodged in NSW since 2019. Per-postcode P10/P50/P90 medians.
Tender Price Index for every Australian capital plus per-trade commentary. Free, current, trusted.
Per-capital USD/m² benchmarks. Calibrates our inter-state factors — Brisbane is now the most expensive AU city.
National building escalation forecasts. Cross-check against RLB and ABS.
Trade-account material pricing across hardware and hydraulics. Anchors line-item materials cost.
City of Sydney, Inner West and growing — public CSVs of every approved DA with cost-of-works.
With consent, we follow up with every customer at 6 and 12 months to capture actual costs. This is the source no competitor can replicate.
Every line in your BOQ shows the spread between sources alongside the mid estimate. Three sources agreeing within 5% — high confidence. Two sources 15% apart — we tell you that, and widen the band. You see exactly which sources informed each number, and when each was last refreshed.
That methodology is documented in full at the methodology page. Refresh cadence is a contractual commitment: if a source is more than one cadence cycle stale at the time your report is signed, we flag it on the cover.
Our pipeline extracts your drawings with AI vision, builds an independent bill of quantities, compares each line against current Australian market rates, and flags every clause that's likely to cost you. Then a human reviews and signs the report before it goes out.
Stripe Checkout. Five minutes. We'll email you a secure link to upload your documents next.
Drag in two PDFs and answer ten short questions about your build. That's it on your side.
AI extracts ~90 line items. A trained reviewer checks every one, runs the comparison against your tender, and writes the red flags and negotiation talking points.
BOQ, line-by-line tender comparison, ranked red flags with dollar impacts, copy-paste negotiation language. Sign with confidence or push back with evidence.
One-page scorecard at the top: total, our independent estimate, delta, verdict (fair / above / significantly above) and the top three actions before signing.
~90 items across substructure, frame, roof, envelope, finishes, services. Each with quantity, unit, market low/mid/high, our total, and a confidence rating.
Trade-by-trade. Where is the margin above norm? Which trades are under-allowed? What looks fair? Each delta shown in dollars and percent.
Critical, warning, info — each with an estimated dollar impact. Missing geotech? Uncapped rise-and-fall? Council infrastructure charges absent? Each one written for you to understand and your builder to respond to.
Eight talking points ranked by likely return. "Please cap rise-and-fall at 5% in line with VIC's 2025 protections legislation." Sentences you can email your builder verbatim.
Every report has a real human's initials on the cover. We will never automate the sign-off. PI insured. Drafted under terms reviewed by an Australian building solicitor.
Pay once for an independent line-by-line audit of your builder's tender. PDF report in 24 hours.
Independent audit of one Australian residential building tender.
Available Australia-wide. Highest calibration confidence in VIC and NSW project-home tenders. Other states: same price, wider confidence band — we tell you on the cover page. Custom build or owner-builder permit? Get in touch — we handle those case-by-case.
No. We're not a licensed quantity surveying practice. We're an independent information service that uses AI document extraction backed by human review. The output uses the same methodology as a QS-style report, but we don't sign certificates of construction cost and we don't accept liability the way a QS firm does.
If you need a stamped QS report for a court, bank, or depreciation schedule, you need a QS firm. If you want to sanity-check the contract you're about to sign for $249 in 24 hours, you want us.
Our most recent benchmark run produced a mid-estimate within 3% of actual cost on a real Australian benchmark project. Each line carries a confidence rating (high / medium / low) so you know which numbers we're sure about and which are estimates. We refresh rates against current Bunnings and Reece pricing weekly, the ABS Producer Price Index quarterly, and re-calibrate against new real-project data as it comes in. The full list of sources and refresh cadences sits at Data sources.
Every report is reviewed and signed by a trained human reviewer before it goes out. We list the reviewer's initials on the report cover. In the first phase, that's the founder personally. As volume grows we'll bring in QS-trained reviewers part-time. We will never automate the sign-off step.
That's a good outcome. Most tier-1 builder tenders we benchmark come in within 3–8% of independent market pricing — that's "fair, upper-band". When that happens, the report tells you so, and then redirects you to the risks: which clauses are uncapped, which inclusions are missing, what to confirm before signing.
The price being fair doesn't mean the contract is. That's most of what we find.
Probably not, if you handle it well. The negotiation language we provide is fact-based and respectful. We never frame the builder as the bad guy. Most builders respond reasonably to a customer who has done their homework. Some don't, and that's a useful signal too.
We store your uploads encrypted for 30 days for QA and dispute purposes, then delete. We may anonymise the structure of your tender (no names, no addresses) to improve our calibration over time. You can request deletion at any time.
We audit residential building tenders Australia-wide for the same $249. Our calibration is most accurate for VIC and NSW project-home builders, where we have the most reference data. QLD, WA, SA, ACT and TAS: same price, wider confidence band — and we tell you exactly what that band is on the cover page of your report. If you're outside a major capital, email us first so we can flag any specific gaps before you order.
We carry professional indemnity insurance and our T&Cs are drafted by an Australian building solicitor. We explicitly limit our liability to refund of the report fee. We are not a substitute for legal review of your contract — we recommend pairing our report with a $400–$900 contract review from a building solicitor.
Pay $249 by Stripe. We'll email you a secure link to upload your documents. A reviewed PDF report arrives in your inbox within 24 hours.
No account required. No subscription. Refund if we can't help.
