What to Look For When Buying a Trades Business in Australia

Buying a trades business in Australia is fundamentally different from buying a cafe, a retail shop, or a professional services firm. The profit is in the vans, the licences, and the repeat customers — not the shopfront. If you're evaluating a plumbing business in Brisbane, an electrical contractor in Melbourne, or an HVAC company on the Gold Coast, the checklist that applies to a generic small business acquisition will miss the things that actually matter.

Here's what to look for.

Why the owner is selling — and whether the answer makes sense

Start here. Every other piece of analysis you do should be filtered through the answer to this question.

The legitimate reasons a trades business owner sells are: retirement, health, a desire to do something else, or they've built it as far as they can and want capital. These are real and common. Tradies in Australia often build a business to a certain size — say $2–4M in revenue — and hit a ceiling they either can't or don't want to break through.

The red flags are: a key contract ending, a licensing issue coming, staff walking out, or a market shift they can see and you can't yet. I've spoken to brokers about deals where the owner was selling a pest control run because the primary property management group they serviced was shifting to a competitor. The business looked fine on paper. The forward order book told a different story.

One rule of thumb: if the business is genuinely growing and profitable and the owner is under 60, you need a very good explanation for why they're exiting now.

Revenue quality — recurring work versus one-off jobs

Not all trades revenue is equal. A plumbing business with five property management contracts producing $40,000 per month in recurring maintenance work is a fundamentally different asset from a plumbing business that does the same revenue entirely through one-off emergency callouts.

Recurring revenue in a trades business comes from:

Property management maintenance contracts (real estate agencies, body corporates)
Service and maintenance agreements (commercial HVAC, fire systems, grease traps)
Subscription or retainer relationships with commercial clients
Local council or government contracts

One-off revenue isn't bad — some of the highest-margin work is one-off (major remediation, large installs, emergency callouts). But it's harder to forecast, harder to value, and harder to retain post-acquisition.

When you're reviewing financials, ask the vendor to break revenue into recurring versus project versus emergency. If they can't, that tells you something about how they run their books (and therefore how they run their business).

This is covered in depth in Module 2 of the Playbook. If you want a practical breakdown, the article on recurring revenue in a trades business is worth reading before you sit down with the financials.

Owner dependency — is it a business or a job?

This is the most common failure point for trades business acquisitions in Australia, and it doesn't get discussed enough.

A trades business that depends on the owner to quote every job, manage every client relationship, and show up on site is not a business — it's a job with better billing rates. When that owner leaves, you're not buying a going concern; you're buying a client list that may or may not stay.

Signs of high owner dependency in a trades business:

The owner answers the phone for all inbound leads and client complaints
No estimating or quoting function exists without the owner
Clients refer to "Dave" not "the company" when they talk about the business
The owner has no admin support and does all the scheduling themselves

Signs of low owner dependency (what you want):

A supervisor or leading hand who manages day-to-day crew operations
An admin or office manager who handles scheduling, invoicing, and supplier relationships
A CRM or job management system (ServiceM8, Simpro, Tradify) with all client and job history in it — not in the owner's head
Clients who have dealt with multiple staff members and don't just know the owner

Owner dependency is one of the biggest drivers of how a business is valued and how risky it is to buy. Use the Owner Dependency Scorecard to assess any business before you get deep into due diligence.

Staff licensing and compliance

This one is specific to trades and it matters a lot.

In Australia, most trades require licences — and those licences sit with individuals, not companies. A plumbing company can only legally operate if it has at least one licensed plumber with a contractor licence. An electrical business needs a licensed electrical contractor. HVAC, pest control, and refrigeration all have their own licence requirements that vary by state.

When you buy a trades business, you need to understand:

Which licences are held by the owner personally? If the owner holds the contractor licence and they're leaving, the business may be unable to operate legally until you arrange a replacement. This transition period is real and needs to be managed.
Which staff are licensed tradespeople versus unlicensed labourers? A painting business that runs on two licensed painters and four unlicensed workers is more exposed than one where four of the six staff are licensed.
Are there outstanding WorkSafe violations, insurance claims, or compliance notices? These are available from the relevant state authority and your solicitor should be checking them as part of legal due diligence.
What's the staff retention risk? If two of your three licensed electricians leave post-settlement because they don't like the new ownership, you have a serious operational problem — not just a people problem.

Equipment, plant, and vehicles

Trades businesses carry real assets. This is one of the reasons they're attractive to buy — there's tangible collateral. It's also one of the ways buyers get stung.

A fleet of five work vans might be listed on the balance sheet at book value. But if those vans are eight years old, have 300,000km each, and need replacing within eighteen months, the "asset" is actually a near-term liability. Same with compressors, excavators, drill rigs, or any specialised equipment.

Before you buy:

Get an independent valuation of all plant and equipment (your accountant or a specialist can do this)
Check when each vehicle was last serviced and obtain the full service history
Ask whether any equipment is leased or financed (if so, the finance pops up in due diligence as an obligation you're taking on)
Find out what maintenance has been deferred — a seller who's been cutting corners on equipment maintenance in the last twelve months is essentially transferring that deferred cost to you

One broker told me about a landscaping business acquisition where the buyer assumed equipment replacement costs were minimal because the assets "looked okay." Within six months of settlement they'd spent $90,000 replacing a tipper and two mowers that the vendor had clearly been running into the ground. The business was profitable — they'd just underestimated the capital cost of keeping it operational.

Customer concentration

If one client represents more than 20% of a trades business's revenue, that's a concentration risk you need to price. If they walk post-acquisition — because they had a relationship with the owner, or they find a cheaper alternative, or the contract simply renews at a worse rate — you've lost a meaningful chunk of the income you paid for.

For trades businesses specifically, watch for:

Heavy reliance on a single real estate agency for maintenance work (these relationships can be personal)
One or two large commercial clients that dominate the revenue
A head contractor relationship — common in construction, where the trades business is a subcontractor to one main builder

The right response to concentration risk isn't necessarily to walk away. It's to adjust the price, negotiate an earn-out structure tied to client retention, or insist the vendor introduces you to key clients before settlement. But you have to identify it first.

The operational due diligence process covers how to map and assess this properly.

The financials — what to look for specifically in trades

Trades businesses in Australia typically run through a company or sole trader structure, and the books can range from immaculate to chaotic. Some things to watch for specifically:

Normalised EBITDA, not reported EBITDA. The owner's personal car through the business, a family member on payroll not actually working there, travel expenses that are really holidays — these are common and need to be added back. But so do genuine one-off items in the other direction. The EBITDA normalisation checklist is useful here.

Job margin by trade or division. A multi-trade contractor might have one profitable division and one break-even division. Don't assess the business as a whole without understanding the margin profile of each revenue stream.

Debtors and work-in-progress. Trades businesses often carry significant WIP — work done but not yet invoiced — and debtors that are 60–90 days past due. This is normal. What you need to understand is whether those debts are collectible or whether there are disputes buried in the numbers.

The gap between what the owner earns and what the business can afford to pay a manager. If you're not working in the business yourself, you need to pay someone to manage operations. If the owner draws $250K per year from a business generating $800K in revenue, but the going rate for a trades manager is $120K, that gap needs to be in your model.

Where to look for trades businesses to buy

The most obvious channel is a business broker — but the best deals often aren't listed. A good overview of the different approaches is in the article on how to find a profitable small business.

Specifically for trades, I'd add:

Industry association directories (MPAQ, NECA, Master Builders) — members in these associations often have relationships with buyers through mutual contacts
Direct outreach to owners in your target trade and region — not aggressive, just an expression of interest
Accountants who act for trades businesses — they often know which clients are considering an exit before any broker does

How to assess whether a trades business is the right fit for you

Beyond the numbers, there's a basic fit question: do you have the management skills to run this type of business, and does the lifestyle work for you?

Trades businesses often involve early starts, on-call emergencies, staff management headaches, and relationships with suppliers and subbies who don't always perform. If you're coming from a corporate or professional background, this transition is real — and underestimating it is one of the reasons acquisitions in this sector fail.

The Business Type Selection Scorecard can help you think through whether a specific trade is actually the right fit before you spend six months in due diligence on something that doesn't suit you.

FAQ

What's the most important thing to check when buying a trades business in Australia?

Owner dependency. If the business can't operate without the current owner, it's a job — not a business. Check whether there's a management layer in place, a job management system, and whether clients deal with staff other than the owner.

Do I need industry experience to buy a trades business?

Not necessarily. Many successful acquirers of trades businesses come from finance, operations, or general management backgrounds. What matters is whether you can manage people, read financials, and deal with the operational demands of running a service business. Industry-specific knowledge helps but isn't the entry requirement.

How do I check if a trades business has licensing compliance issues?

Your solicitor and accountant should check this as part of legal and operational due diligence — including searches with the relevant state licensing authority (QBCC in Queensland, VBA in Victoria, NSW Fair Trading for NSW, etc.). Ask specifically about any licence suspensions, complaints, or insurance claims in the last five years.

What's a fair multiple for a trades business in Australia?

Most trades businesses in Australia sell at 2–3.5x normalised EBITDA, depending on revenue quality, owner dependency, contract mix, and business size. Higher-value trades (electrical, HVAC, specialised mechanical) can command toward the top of this range. For a specific trade, see the industry valuation articles — for example, how much a plumbing business is worth.

What job management software should I look for when evaluating a trades business?

ServiceM8, Simpro, Tradify, and AroFlo are the most common in Australia. Businesses using proper job management software have documented processes, client histories, and scheduling systems that survive the owner's departure. A business running everything in spreadsheets and memory is a higher-risk acquisition.
