Who sends us residential plans
The house is documented. The pricing is the bottleneck.
Most residential jobs are lost or won before a brick moves — in the week spent measuring off drawings instead of talking to the client. EstiFlow does that measuring and pricing pass for you, and hands back something you can put in front of an owner the same week the plans land.
Builders pricing a new home
A knockdown-rebuild, a new house or a spec build. Every trade measured from the issued drawings, with the assumptions and exclusions written down instead of buried in a spreadsheet.
Alterations, additions and renovations
Existing-fabric work priced at the same tier as a new build of the same dwelling count. Demolition, make-good and the interfaces with retained structure are identified, not assumed away.
Duplex, triplex and townhouse developers
Up to 15 dwellings on one site, with the scope separated per unit and extra scrutiny on the trades that move a multi-unit number.
Plans in, a complete pack out
Three deliverables, and they agree with each other.
The report, the workbook and the trade packs come out of the same measured take-off, so the number you read in the report is the number the BOQ builds up to and the scope the subcontractor prices.
A Cost Estimate Report that explains the project
The number at a glance, the elemental cost plan, where the money sits, certainty package by package, the items that move the figure, the programme and the builder’s brief.
An editable costed BOQ workbook
Quantity, unit, rate and total on every line, with live formulas. Drop in your own supplier and subcontractor rates and the totals follow.
Subcontractor pricing packs
Per-trade scope and quantities with EstiFlow rates removed, ready to send so every return you compare is priced against the same work.
Supported inputs: PDF, JPG, PNG, TIFF, DOCX, XLSX, IFC, DWG, SketchUp, LandXML, ZIP archives. DA-stage architectural plans are enough to start — send the rest of the set if you have it and the relevant scope tightens.

Residential builders using it now
Their words, on their own projects.
Rise Up Constructions
“I used EstiFlow for a second opinion on a $1.7M alterations and additions project in Bronte. What came back genuinely surprised me — far more comprehensive than the other platforms I've tried, and the price landed almost exactly where my own tender pricing was. It picked up the conflicts buried in my consultants' documents and priced the risks honestly instead of glossing over them. I've already passed EstiFlow on to other builders.”More builder testimonials →
BWR Building
“Sent the plans for a triplex through and got back every trade broken out. It picked up a couple of things I'd have had to go back and add if I'd priced it myself.”More builder testimonials →

A straightforward next step
From your plans to a price you can defend.
Pick the dwelling count
Granny flat, house, duplex, triplex or townhouse development. The tier and the price are fixed before you upload anything.
Send the documents you have
DA-stage plans are enough. Add the engineering, schedules, specification or model files if you have them and the relevant scope tightens.
Review the pack and price the job
Read the report, apply your own rates in the BOQ, and send the trade packs out for comparable returns.

Watch a quick explanation, then explore the pack or talk to us about your project.
Before you send the plans.
What do I receive?
A Cost Estimate Report that explains the project, an editable costed BOQ workbook with the quantity, unit, rate and total on every line, and rate-stripped subcontractor pricing packs you can send straight to trades. An indicative construction programme and the interactive dashboard come with every residential tier.
Which tier is my project?
Residential is priced by dwelling type and dwelling count: a granny flat, one house, a duplex, a triplex, or a townhouse development up to 15 units. Alterations and additions, extensions and renovations sit in the same tier as a new build of the same dwelling count. Every price is published before you upload.
How quickly will it arrive?
Residential estimates and Trade Estimate Packs are typically delivered within 1 business day from payment and a complete document set. Major-project timing is agreed with your quote.
What documents do I need?
DA-stage architectural plans are enough to start. Send whatever else you have — NatHERS or BASIX, structural, geotechnical, services, finishes and landscape documents all tighten the relevant scope. Accepted formats: PDF, JPG, PNG, TIFF, DOCX, XLSX, IFC, DWG, SketchUp, LandXML, ZIP archives.
How are assumptions and provisional items handled?
The report keeps measured, provisional and excluded scope distinct, and states the assumption behind every provisional line so nothing is silently priced. Before you send the job to tender, review the provisional items and the decisions the report flags — they are prioritised by how much each could move the number.
Is this a certified quantity surveyor report?
No. EstiFlow is not a registered, certified, or licensed quantity surveying practice. You receive a detailed construction estimate prepared from your documents, intended to support your own commercial judgement, not to replace a signed report from a qualified professional.
Is this software I need to learn?
No — it is a service, not software. Send the plans and EstiFlow prepares the estimate pack for you. There is no estimating software to learn, no subscription, and no account needed to start.
Can I use my own rates?
Yes. The BOQ workbook keeps live formulas and editable pricing inputs, so you can drop in your own supplier and subcontractor rates and watch the total move. Your rates and margins stay yours.
What if the estimate is not useful?
Your first paid EstiFlow estimate carries a money-back guarantee. Email info@estiflow.com.au within 7 calendar days of delivery with your job reference and we refund that estimate in full — no supporting evidence and no dispute process required.
Need a QS-signed council report, or another quantity surveying service, separately from your EstiFlow estimate? CouncilQS, powered by EstiFlow, prepares QS-signed residential council reports as its own separate product and assesses other QS requests individually — an EstiFlow estimate pack is not a certified report.
EstiFlow is not a registered, certified, or licensed quantity surveying practice. EstiFlow provides an automated construction estimating service · not a licensed quantity surveyor. Outputs are automated cost estimates intended to support, not replace, professional judgement.
