Best Bill of Quantities Software for Australian Construction: A Buyer’s Guide
The best Bill of Quantities (BoQ) software for Australian construction is whichever tool turns your measured quantities and your own rates into a structured, editable, client-ready priced document — organised by trade section, with provisional sums, prime cost items and preliminaries handled properly, and nothing hidden or locked away from you. This guide sets out the criteria to judge any BoQ software against, then shows where My Trade Hub fits as one option among several.
Key takeaways
- Good BoQ software organises items into structured trade sections, not one long undifferentiated list.
- Every measured item needs a clear description, a standard unit and an accurate quantity — vague lump sums are a warning sign.
- Rate build-up should apply your own labour, material and plant rates, and every rate must stay visible and editable.
- Provisional sums and prime cost items need to be clearly separated from firm-priced items, not buried in a total.
- The output should export as a clean, client-ready document once you’ve reviewed and adjusted every line.
| Criterion | What to look for | My Trade Hub |
|---|---|---|
| Structured trade sections | Organises items by trade or work section (concrete, carpentry, electrical and so on) so a large document stays navigable and reviewable section by section. | Groups measured items by trade section automatically when it generates the Bill of Quantities from your takeoff, matching how Australian tenders are typically structured. |
| Measured items with descriptions, units and quantities | Each line should carry a clear description, a standard unit (m, m², m³, no., item) and an accurate quantity — not a lump-sum guess. | Populates BoQ line items directly from automated quantity takeoff, so descriptions, units and quantities reflect what was actually measured off the plans. |
| Rate build-up | Should apply your own labour, material and plant rates to each measured item rather than relying on a generic average you can’t see or verify. | Applies your editable rates library to each measured quantity, and every rate stays visible and adjustable — nothing hidden inside a black-box average. |
| Provisional sums and prime cost items | Must let you flag items that can’t be firmly measured or priced yet (subject to a subcontractor quote or client selection) as PS or PC items, kept separate from firm prices. | Lets you add and edit provisional sum and prime cost line items alongside measured items, so they stay clearly marked in the priced BoQ rather than buried in a total. |
| Preliminaries | Should have a proper place for site establishment, supervision, insurances and other project-wide costs that sit outside individual trade items. | Provides line items for preliminaries within the same BoQ structure, so they’re priced and presented alongside trade sections rather than left off entirely. |
| Editable after generation | Automation should be a starting point, not a final answer — you need to add, delete, re-describe or re-price any line before it goes to a client. | Every generated line — quantity, description, rate or total — stays fully editable, since My Trade Hub applies the rates and structure you control, not a fixed formula. |
| Client-ready export | Needs to export as a clean, shareable document formatted for a tender submission, not just a raw spreadsheet dump. | Exports the priced Bill of Quantities as a client-ready document formatted for tender submission once you’ve reviewed and adjusted every line. |
What Bill of Quantities Software Actually Needs to Do
Bill of Quantities (BoQ) software takes a set of measured quantities — from a takeoff, a spreadsheet or manual measurement — and turns them into a structured, priced document that a client or head contractor can read and act on. The job of the software is narrower than general “estimating”: it is specifically about producing that structured list of items, units, quantities, rates and totals in a format the Australian construction industry recognises.
Before comparing tools, it helps to be clear on what a BoQ is not. It is not a single lump-sum quote, and it is not a generic spreadsheet template with no trade structure. A proper BoQ separates the project into trade sections, gives each item a measurable unit, and prices it against a rate — so anyone reviewing it can see exactly what is included and what it costs, item by item.
Structured Trade Sections
The first thing to check is whether the software organises items by trade or work section — concrete, carpentry, electrical, plumbing and so on — rather than dumping every measured item into one flat list. Australian tenders are usually reviewed section by section, often by different people (an estimator checking concrete quantities, a site manager checking electrical), so a BoQ that isn’t structured this way is harder to use and easier to make mistakes in.
Look for software that lets you add, rename or reorder trade sections to match the actual scope of the job, rather than forcing every project into a fixed template that suits a commercial fit-out but doesn’t fit a residential renovation.
- Sections should match how the job is actually being built, not a rigid one-size-fits-all list
- Reviewers should be able to jump to a single trade section without reading the whole document
- Renaming and reordering sections should be simple, not a manual workaround
Measured Items — Descriptions, Units and Quantities
Every line in a BoQ should carry three things: a clear description of the work, a standard unit of measurement (m, m², m³, no., item, kg), and a quantity that reflects what was actually measured — not a rounded estimate. This is the core of what separates a BoQ from a quote: the reader can see how much of something is being supplied or installed, not just a final number.
If a tool produces items without a real unit, or with descriptions vague enough to cover almost anything, that’s a sign it’s built for speed rather than for a document you’d actually hand to a client. Ask how quantities are generated — from a genuine takeoff off the plans, or from a rough allowance — because that answer shapes how much manual checking the BoQ still needs before it goes out the door.
Rate Build-Up — Turning Quantities Into Prices
Once quantities are measured, the software needs to apply a rate — a unit price — to each item to produce a line total. Good BoQ software lets you build that rate from labour, material and plant components, or apply a single all-in unit rate, and — critically — lets you see and adjust the rate behind every line rather than hiding it behind an average.
Be wary of any tool that claims to generate rates for you from a generic database without letting you see or change them. Rates vary by region, supplier relationship and current market conditions in ways no generic database can track accurately, so the rates in your BoQ should always be the ones you supply and control.
| Item | Description | Unit | Quantity | Rate (AUD) | Amount (AUD) |
|---|---|---|---|---|---|
| 1.1 | Supply and place N32 concrete slab, 150mm thick, including reinforcement | m² | 85 | 95.00 | 8,075.00 |
| 1.2 | Formwork to slab edge, up to 150mm | m | 42 | 18.50 | 777.00 |
| 1.3 | Provisional sum — geotechnical remediation, subject to site inspection | item | 1 | — | 5,000.00 (PS) |
Why the source of the rate matters
A BoQ is only as reliable as the rates behind it. Software that applies your own, editable rates to measured quantities gives you a document you can stand behind in a tender. Software that guesses a rate on your behalf is still a guess — just one with your name on the price.
Provisional Sums and Prime Cost Items
Not everything in a job can be measured and priced with certainty at tender stage. Items still subject to a subcontractor quote, a client selection (tiles, fittings, appliances) or a site condition that won’t be known until work starts need to be flagged as provisional sums (PS) or prime cost items (PC) — an allowance, clearly marked as an allowance, rather than a firm price dressed up as one.
BoQ software should let you add PS and PC items alongside measured items, label them clearly, and keep them visually distinct in the final priced document. A tool that forces every line to look like a firm, measured price — with no way to flag an allowance — can leave you exposed if costs move once the real figure is known.
Preliminaries
Preliminaries cover the costs that sit outside any single trade — site establishment, supervision, insurances, temporary fencing, waste removal and similar project-wide items. They’re easy to under-price because they don’t belong to a trade section, so BoQ software needs a proper place for them rather than leaving you to remember them as an afterthought.
Check whether preliminaries appear as their own section in the exported document, priced and itemised the same way as trade items, rather than folded into a single contingency line that hides what’s actually been allowed for.
Where My Trade Hub Fits
My Trade Hub is one option in this category, and it’s worth being specific about what it does. It generates a structured Bill of Quantities from automated quantity takeoff — measurements taken from uploaded plans — combined with your own editable rates library. The BoQ it produces is organised by trade section, and every line — quantity, description, rate or total — stays fully editable after generation, because My Trade Hub applies the rates and structure you’ve set, not a hidden formula.
That’s the extent of the claim: My Trade Hub doesn’t grade the accuracy of its own takeoff, and it doesn’t connect to any accounting package. Estimating and BoQ generation sit in the paid Starter, Scale or Professional plans (priced in AUD, no lock-in contracts) — creating a My Trade Hub account is free, but that free tier covers the contractor marketplace (posting jobs, browsing tenders, receiving quotes), not producing priced BoQs. It’s worth comparing directly against whatever else you shortlist.
Editability and Exporting a Client-Ready BoQ
However quantities and rates get into the document, the software has to let you change every part of it before it goes anywhere near a client. Automated measurement and rate application are a starting point — plans get misread, scope changes, a client asks for a variation before the tender even closes. If a line can’t be corrected, added or deleted without starting over, the tool is creating rework rather than saving time.
Finally, check the export. A BoQ that only exists inside the software isn’t much use for a tender submission — it needs to export as a clean, formatted, client-ready document (typically a PDF), with trade sections, preliminaries, provisional sums and totals presented the way the industry expects to see them.
- Confirm you can edit descriptions, units, quantities and rates after generation — not just before
- Check the exported format matches what your clients or head contractors expect to receive
- Ask whether provisional sums and preliminaries appear clearly in the export, not just the on-screen view
Frequently asked questions
What is Bill of Quantities software?
Bill of Quantities software takes measured quantities from a construction project and turns them into a structured, priced document organised by trade section — with descriptions, units, quantities, rates and totals for each item. It’s a specific type of tool, distinct from general quoting or invoicing software, focused on producing the itemised pricing document used in Australian tendering.
What should I look for in BoQ software for construction tenders?
Look for structured trade sections, measured items with real units and quantities (not lump-sum guesses), rate build-up using your own labour, material and plant rates, proper handling of provisional sums and prime cost items, a place for preliminaries, full editability after generation, and a clean, client-ready export.
Does BoQ software calculate rates for me?
It shouldn’t calculate rates on its own without your input. Reliable BoQ software applies rates you supply — your own labour, material and plant prices — to the quantities it has measured. Be cautious of any tool that generates rates from a generic database without letting you see or change them, since rates vary too much by region and supplier to be reliable as a fixed average.
What’s the difference between a Bill of Quantities and a quote?
A quote is typically a single price, or a small set of prices, for a job. A Bill of Quantities is a structured, itemised breakdown — organised by trade section, with a description, unit, quantity and rate for every measured item — that shows how the total price was built up, not just what it adds up to.
Can I edit a Bill of Quantities after it’s generated?
In good BoQ software, yes — every line should stay editable after generation, including descriptions, units, quantities and rates. Automated measurement and rate application are a starting point; scope changes and corrections are normal, so the software needs to let you adjust any line before it goes to a client.
Is My Trade Hub’s Bill of Quantities generator free?
Creating a My Trade Hub account is free, and that free tier covers the contractor marketplace — posting jobs, browsing tenders and receiving quotes. Generating a Bill of Quantities from quantity takeoff and your rates library is part of the paid Starter, Scale or Professional plans, priced in AUD with no lock-in contracts. See the pricing page for current plan details.
How are provisional sums shown in a Bill of Quantities?
Provisional sums and prime cost items should appear as their own clearly labelled lines within the relevant trade section — flagged as an allowance rather than a firm measured price — so anyone reading the BoQ can see exactly which costs are still subject to a quote, a client selection or a site condition.
