Construction has the worst late-payment record and the highest insolvency rate of any industry in the country. Here is what slow and non-payment actually costs, and what you can do about it.

Ask any builder who has been in business for more than a few years and they will have a story about money they earned but never collected. A progress claim that sat unpaid for months. A variation that was agreed on site and then disputed at the end. A head contractor who went under owing them tens of thousands, leaving them at the back of a long queue of creditors hoping for cents in the dollar.

These are not isolated incidents. They are a structural feature of the way construction works in Australia, and they cost the industry an enormous amount of money every year.

The hard part is putting a precise national figure on it. There is no single agency that measures the total value of slow and unpaid construction work in Australia. But the data that does exist paints a clear and uncomfortable picture. Construction has the worst late-payment record of any industry in the country, the highest insolvency rate, and a supply chain structure that pushes financial risk down onto the smallest businesses least able to carry it.

Construction Is the Worst-Paid Industry in Australia

Start with the late-payment data, because it is the clearest signal of the problem.

Credit reporting agency CreditorWatch has repeatedly found that construction experiences the highest levels of late payment of any industry in Australia. In its business sentiment research, 92 per cent of construction firms reported having overdue invoices over a 12-month period, with 39 per cent reporting invoices overdue by more than 30 days at a time.

The pattern has not improved. By early 2026, CreditorWatch reported late payments across the economy had hit their highest rate in six years, with construction again among the worst-affected sectors. Industry data puts average payment times to small construction businesses at somewhere between 32 and 50 days or more, and around 11.6 per cent of small construction businesses are carrying payments overdue by more than 60 days at any given time.

Put plainly, more than one in ten small construction businesses is owed money that is already two months late.

The reason this matters so much is structural. Construction runs on a payment chain. A principal pays a head contractor. The head contractor pays subcontractors. Subcontractors pay their own suppliers and trades. Money flows down that chain in stages, and every link adds delay. When a payment is held up at the top, the businesses at the bottom are the ones who run out of cash first, because they have the thinnest buffers and the least leverage to chase what they are owed.

That is why the same survey data shows the pain falling hardest on sole traders and small firms. A large national contractor can absorb a 60-day delay. A two-person formwork crew often cannot.

The Real Cost Is Bigger Than the Late Invoice

A late payment is not just a number on an overdue ledger. It carries a series of downstream costs that rarely get added up.

When money arrives late, builders bridge the gap somehow. That usually means an overdraft, a line of credit, supplier credit terms stretched to their limit, or in the worst cases a director lending personal money into their own company to make payroll. Every one of those options has a cost, whether it is interest, fees, or personal financial risk.

Then there is the time. Chasing payment is unpaid administrative work. Hours each week spent on phone calls, follow-up emails, reissued invoices and awkward conversations are hours not spent quoting, building, or running the business. For a small operator who is also the estimator, the site supervisor and the bookkeeper, that time is genuinely expensive.

There is also the opportunity cost. When cash is tied up in receivables, builders cannot confidently bid for new work, even when the pipeline is strong. Some turn down profitable jobs simply because they cannot fund the upfront costs while waiting to be paid on the last one. Growth stalls, not because the work is not there, but because the cash is stuck.

The money does not vanish. It gets baked into prices, and the whole industry pays for it.

And finally there is the risk premium. Contractors who have been burned start pricing payment uncertainty into their bids. They add a margin to cover the possibility of slow payment, or they refuse to work for certain clients altogether. International research on construction payments has estimated that slow payment adds well over ten per cent to project costs in some markets through exactly this mechanism.

When Slow Payment Becomes No Payment

The most severe version of the payment problem is insolvency, and here the Australian data is stark.

Construction is consistently the single largest source of business failure in the country. In 2023-24, the Australian Securities and Investments Commission reported that construction accounted for around 27 per cent of all companies entering external administration, the highest of any industry.

The volume has been climbing fast. ASIC recorded 14,722 corporate insolvencies across all industries in 2024-25, the highest annual figure since records in their current form began in 1999-2000, and well above the pre-COVID average of roughly 8,200 a year. Construction made up the largest single share of those failures. Master Builders Australia’s own insolvency tracking put construction company collapses in the thousands for the year, the equivalent of roughly nine construction businesses failing every working day.

For a subcontractor or supplier, a head contractor collapse is the worst-case scenario. When a builder goes under, the subbies who did the work become unsecured creditors. They sit behind the banks, the tax office and other secured parties in the queue. In practice, unsecured creditors in a construction liquidation often recover almost nothing.

The pattern has played out in some of the largest collapses in recent memory. When major builders have failed, they have left behind hundreds or thousands of creditors and hundreds of millions of dollars in unpaid debts, with trade creditors frequently told to expect little or no return while secured lenders are repaid in full. The headline collapses get the coverage, but the same dynamic repeats thousands of times a year in smaller, quieter liquidations that never make the news.

This is the link between slow payment and non-payment that builders need to understand. A client who is slow to pay is not just an inconvenience. Slow payment is one of the strongest early-warning signs of a business in trouble. CreditorWatch data has found that a business with even a single payment default has a materially higher chance of failing within 12 months, and that risk climbs sharply with each additional default. By the time a slow payer becomes a non-payer, the money is usually gone.

Why the System Is Built This Way

None of this is new, and it is not an accident. The structure of the industry produces it.

Construction is highly fragmented and dominated by small firms operating on thin margins with limited financial buffers. Work is subcontracted down a hierarchical chain, which means the businesses doing the physical work are usually furthest from the money. Fixed-price contracts transfer cost risk downward. Retention is held back from payments as security. Variations are a constant source of disagreement about what was agreed and who owes what.

Each of these features, on its own, is manageable. Stacked together, they create an environment where payment disputes are not the exception but a normal cost of doing business.

Australia has spent years trying to fix this through legislation. Every state and territory has security of payment laws designed to give contractors and subcontractors a fast, low-cost way to recover progress payments without going to court. These laws give you the right to make a payment claim, oblige the other party to respond within set timeframes, and provide for rapid adjudication by an independent adjudicator, often within around ten days. They also void “pay when paid” clauses written into construction contracts, which used to let head contractors withhold payment to subbies until they themselves were paid upstream.

The reforms keep coming. The federal government responded to the Murray Review in March 2025, backing a more nationally aligned approach to payment security while leaving the actual legislation to the states. Victoria passed significant reforms in late 2025, due to take effect through 2026, including new powers for adjudicators to void unfair time-bar clauses and requirements for retention money to be held in trust. The federal Payment Times Reporting Scheme now publicly identifies the slowest large-business payers, and the regulator issued its first directions against slow payers in the 2025-26 cycle.

These measures help. But they work only for the contractors who use them, and they sit on top of a payment culture that remains deeply entrenched. The law gives builders rights. It does not automatically give them their money.

What Builders Can Actually Control

The macro picture is sobering, but the practical lesson is not that builders are powerless. The businesses that come through this in the best shape tend to do the same unglamorous things consistently.

Get the paperwork right before work starts. A clear written scope, signed before anyone is on site, removes the single most common source of payment disputes. Most arguments at the end of a job are arguments about what was agreed at the start.

Document every variation in writing, priced and approved, before the work is done. Not after. Not verbally. A variation agreed with a nod on site and disputed three months later is money you will probably never see.

Issue progress claims the moment a stage is complete, and issue them correctly. Security of payment legislation is powerful, but it is also technical. A claim that does not comply with the requirements can be worthless. A claim issued promptly and properly is the foundation of every recovery option you have.

Watch your clients for warning signs. Stretching payment terms, frequent disputes over small amounts, and an unusual reliance on the next job’s deposit to pay the last job’s bills are all signals worth taking seriously. The time to tighten terms with a slow payer is before they become a non-payer, not after.

Act early when a payment goes overdue. The data is unambiguous on this. Recovery rates are highest in the first 30 to 60 days after a payment falls due and collapse once a debt reaches formal insolvency. A prompt, professional letter of demand recovers more money, at lower cost, than almost any later step. Waiting and hoping is the most expensive strategy there is.

And know which legislation applies to you. Security of payment laws differ across states and territories, and the right process in Queensland is not the right process in Victoria or New South Wales. Knowing your rights, and the timeframes that come with them, before you are in a dispute is worth far more than learning them in a panic afterwards.

The Bottom Line

There is no official national tally of how much Australian builders lose every year to slow and non-payment, and any single figure should be treated with caution. But the direction of the evidence is not in doubt. Construction has the worst late-payment record and the highest insolvency rate of any industry in the country. The cost runs into the billions when you add up the unpaid invoices, the financing to bridge the gaps, the lost time, the foregone work, and the risk premiums baked into every bid.

The uncomfortable truth is that a large share of this is structural and will not be fixed by any builder acting alone. But the share that is within your control is not small. The fundamentals of running a building business that holds together under pressure — clear contracts, disciplined documentation, prompt and correct claims, and acting fast when money is late — will not insulate you from a head contractor collapse. They will, however, put you in a far stronger position than the builder next door who shook hands on a price and hoped for the best.

Your Questions Answered:

How much do Australian builders lose to late payment each year?

There is no official national figure, and you should be cautious of anyone who quotes one with confidence. No single agency measures the total value of slow and unpaid construction work in Australia. What the data does show is the scale of the problem. Construction has the worst late-payment record of any industry in the country, with around 11.6 per cent of small construction businesses carrying payments overdue by more than 60 days at any given time. Once you add the financing used to bridge the gaps, the unpaid administrative hours, the work turned down because cash is stuck, and the risk premiums builders bake into bids, the cost runs into the billions. The honest answer is that it is large, measurable in its effects, and impossible to state as one precise number.

Which industry has the worst payment record in Australia?

Construction. Credit reporting agency CreditorWatch has repeatedly found that construction experiences the highest levels of late payment of any industry in Australia, with 92 per cent of construction firms reporting overdue invoices over a 12-month period. It is also the single largest source of business failure in the country. The reason is structural. Construction runs on a payment chain, where money flows down in stages from principal to head contractor to subcontractor, and every link adds delay. The businesses doing the physical work usually sit furthest from the money and have the thinnest buffers to absorb a hold-up.

What is security of payment legislation?

Security of payment legislation is a set of laws, with a version in every state and territory, designed to give contractors and subcontractors a fast, low-cost way to recover progress payments without going to court. The laws give you the right to make a payment claim, oblige the other party to respond within set timeframes, and provide for rapid adjudication by an independent adjudicator, often within around ten days. They also void “pay when paid” clauses, which once let head contractors withhold payment from subbies until they were paid upstream. The catch is that the laws are technical, the process differs by state, and they only protect the contractors who actually use them correctly. A payment claim that does not comply with the requirements can be worthless.

What happens to subcontractors when a builder goes into liquidation?

It is the worst-case scenario for the payment chain. When a head contractor collapses, the subbies who did the work become unsecured creditors. That means they sit behind the banks, the tax office and other secured parties in the queue for whatever is left. In practice, unsecured creditors in a construction liquidation often recover almost nothing. The pattern has played out in the largest collapses in recent memory, where major builders have left behind hundreds or thousands of creditors and hundreds of millions in unpaid debts, with trade creditors frequently told to expect little or no return while secured lenders are repaid in full. The same dynamic repeats thousands of times a year in smaller liquidations that never make the news. This is why a slow-paying client is worth watching closely. Slow payment is one of the strongest early-warning signs of a business in trouble, and by the time a slow payer becomes a non-payer, the money is usually gone.

How quickly should you chase an overdue construction invoice?

Early, and the data is unambiguous on this. Recovery rates are highest in the first 30 to 60 days after a payment falls due, and they collapse once a debt reaches formal insolvency. A prompt, professional letter of demand recovers more money, at lower cost, than almost any later step. Waiting and hoping is the most expensive strategy there is. The practical move is to issue progress claims the moment a stage is complete, follow up the instant a payment is late, and act rather than let an overdue invoice drift, because every week that passes lowers the odds of seeing the money.
