How much does a trades or construction business valuation cost in Australia.

Why trades has the widest tier spread of any industry

A trades or construction business valuation in Australia typically costs from $1,495 + GST at Prismi's Essential tier for a simple sole-trade licence holder, up to $8,995 + GST or more where work-in-progress, retentions or multiple entities are involved — with traditional firms commonly charging $5,000–$15,000+ for a comparable full report. That spread exists because the honest answer to "what does it cost" depends more on the shape of the business than in almost any other industry Prismi values. A sole-trade electrician with a ute, a handful of residential jobs on the go and no employees sits at the bottom of the market — the work is close to valuing a job, not an enterprise. A mid-size contracting company with a project pipeline, subcontractor panels, retentions held on multiple jobs and percentage-of-completion revenue recognition is a different engagement altogether, closer in complexity to valuing a professional services firm with long-dated contracts. Between those two poles sits every plumbing outfit, shopfitting business, civil subcontractor and building company in the country, and trades is one of the industries where that market range genuinely reflects the underlying complexity spread rather than firms simply charging what the market will bear.

The tier spread explained

At the bottom band: a sole trader or single-entity licence holder with straightforward job-costing, no work-in-progress carried across balance dates, and earnings that are really the licence holder's labour plus a modest margin. This is often the least complex valuation Prismi prepares — a single methodology capitalising normalised earnings, with the labour-versus-profit split as the main analytical question. At the top band: a contracting company with multiple concurrent projects, retentions receivable and payable, subcontractor liabilities, plant financed across several facilities, and revenue recognised on a percentage-of-completion basis that does not map cleanly to cash received. This requires construction-specific balance-date adjustments before any valuation methodology can even be applied, plus scrutiny of the order book as forward-earnings evidence. The fee difference between these two engagements is not arbitrary — it reflects materially more analytical hours.

The WIP driver: why percentage-of-completion accounting changes the work

Most trades and construction businesses above a certain size recognise revenue using percentage-of-completion, not on invoicing or cash receipt. That means reported earnings at any balance date include unbilled revenue on jobs still underway, offset by costs incurred but not yet recovered. Under-billings (costs incurred ahead of billing) and over-billings (billing ahead of costs incurred) both distort a raw earnings figure if left unadjusted — a business that looks highly profitable at year-end may simply be sitting on a pile of over-billed cash it owes back in future-period costs. Retentions held by principal contractors (commonly 5–10% of contract value, released on practical completion and again at the defects liability period) also need to be identified and treated correctly — as a receivable with timing risk, not as realised earnings. This construction-specific balance-date work is the single biggest reason a contracting company's valuation costs more than a simple trade business of similar revenue, and it is why a valuer who has not worked with WIP schedules before can materially misstate maintainable earnings.

The licence-dependency driver

In most Australian states, operating as a licensed builder, electrician, plumber or gasfitter requires a nominated individual to hold the relevant licence or registration — and the business's ability to legally continue trading, tender for work, or hold professional indemnity and home warranty insurance can depend on that person remaining involved. A valuer has to ask a question that does not arise in most other industries: what happens to this business's earning capacity if the licence holder leaves, retires, or is unable to continue? Where the business has multiple licensed staff, documented succession arrangements, or the licence sits with the corporate entity rather than a single individual, key-person risk is lower and the earnings multiple can reflect that. Where the entire licensed capacity rests on one person with no identified successor, a key-person discount is generally applied — the same way it would be for a medical practice or law firm built around a single principal. This is assessed on the specific facts of the business, not assumed either way.

Pipeline versus history: weighing the order book

Most valuation methodologies look backward — normalised historical earnings, capitalised at an appropriate multiple. Trades and construction businesses often argue their forward order book is a better indicator of maintainable earnings than trailing figures, particularly where a business has just won a larger contract or moved up a tender panel. This evidence matters, but it has to be weighed carefully: a signed contract with a committed principal is materially different evidence to a verbal in-principle award; a tender win rate calculated over 30 tenders is more reliable than one calculated over four; and project concentration — where a large share of the order book sits with one or two principals or one large job — is itself a risk factor that can offset the apparent benefit of a strong pipeline. The valuer's job is to weigh this forward-earnings evidence against the historical base, not to simply substitute the bigger number.

Plant and vehicles: owned versus financed, and what they're actually worth

Trades and construction businesses typically carry a fleet of vehicles and, depending on the trade, plant and equipment — excavators, scaffolding, generators, specialised tools. Two questions matter for valuation purposes. First, ownership: equipment under finance or hire-purchase sits differently on the balance sheet than owned assets, and the net position (asset value less remaining finance liability) is what feeds into a net asset value cross-check, not the gross asset figure. Second, market value: book value (cost less depreciation) frequently diverges from what plant and vehicles would actually realise if sold, particularly for older equipment that has been well maintained or, conversely, run hard on-site. Where plant and equipment forms a meaningful share of the business's value — as it often does for civil, earthmoving or larger construction outfits — verifying market value against comparable sale evidence, rather than relying on the depreciation schedule, is part of a properly evidenced valuation.

Prismi's fixed-fee tiers

What decides your tier

Retrospective valuation dates add $495 per historical date; additional related entities (common where a trading company sits alongside a separate plant-holding or property entity) add $750 each; rush turnaround adds 30% on top of the standard timeframe for the tier. In practice, the questions that push a trades or construction business up the tier ladder are: does the business carry work-in-progress across a balance date, does it hold retentions, is more than one entity involved, and does its earning capacity depend materially on one licensed individual. A sole trader with none of these factors is genuinely an Essential-tier engagement. A contracting company with all of them is a Defensible or Scenario Review engagement, and pricing it as anything less would mean skipping analysis the business actually needs.

When Essential is enough, and when it is not

Essential suits a sole-trade or single-entity licence holder with straightforward job-costing, no work-in-progress carried across a balance date, and a single owner-operator earnings driver — one methodology plus a senior review gets to a supportable position efficiently. It is not the right scope where the business recognises revenue on a percentage-of-completion basis, holds retentions receivable or payable, spans more than one entity, or where earning capacity depends materially on a single licence holder with no identified successor. It is also not suited to a matter that could face ATO review, a related-party transfer, or a shareholder dispute, where the file needs to withstand scrutiny rather than just produce a number. In those cases, stepping up to Comprehensive or the Defensible Valuation File is not paying for more paperwork — it is paying for the WIP reconciliation, retentions analysis and evidence pack the file actually needs to be supportable.

The honest trade-off, and where to go next

The Essential tier is priced from $1,495 + GST because its scope is fixed, not because corners are cut: one methodology, applied properly, senior-reviewer signed, with the working file retained for ten years. For a straightforward sole-trade licence holder with clean job-costing and no material WIP, that is a complete and proportionate report. But be honest about what a single methodology cannot do. It does not produce the cross-checked supportable range that contested matters need, and it is not suited to family law, partnership disputes or positions carrying realistic ATO-dispute risk — for those, stepping up to Comprehensive or the Defensible Valuation File at engagement is far cheaper than commissioning a second valuation after a thin one is challenged. If in doubt, the discovery call will confirm the right tier before the engagement starts — fees are fixed once the scope is agreed, not adjusted afterward.
