Debt Collectors vs Security of Payment Act: Which Gets You Paid Faster

You’re owed money. A client or head contractor has ghosted your invoices. Your first instinct might be to hire a debt collector. But before you sign away a cut of your debt, there’s a faster, cheaper option most Australian tradies don’t know about: the Security of Payment Act.

This post compares the two approaches—not as legal advice, but as practical guidance on what actually works for construction workers and small builders chasing unpaid invoices.

How Debt Collectors Work (And What They Cost)

Traditional debt collectors operate on commission. They typically take 10–20% of what they recover, sometimes more. They’ll send letters, make calls, and occasionally escalate to legal action. The process is slow: expect 3–6 months minimum before any real pressure lands on the debtor.

Here’s the catch: debt collectors have no legal advantage. They’re just a third party chasing money using standard contract law. If the debtor ignores them, your debt joins thousands of others in their pipeline. And if the debtor has no money—or won’t cooperate—the collector can’t force payment. They can only refer you to a court case, which costs thousands more.

Commission fees also eat into what you recover. If a collector gets your $10,000 back, you pocket $8,000–$9,000. That’s money out of your pocket for a service you could potentially handle yourself.

The Security of Payment Act: A Faster Legal Pathway

Every Australian state has a Security of Payment Act designed specifically for construction disputes. In New South Wales, it’s the Security of Payment Act 1999. Queensland has the Building Industry Fairness (Security of Payment) Act 2017. Victoria has the Security of Payment Act 2002. Each state has its own version, but they all work on the same principle: subcontractors, suppliers, and tradies can lodge a payment claim and force the other party into formal adjudication within tight timeframes.

Here’s what makes it different:

1. Speed: The respondent (person who owes you) has 10 business days to respond with a payment schedule. If they don’t, you win by default.
2. Formal process: Unlike a debt collector’s informal pressure, this is a statutory right. The debtor knows you’re serious.
3. Low cost: Filing a claim costs a fraction of what a debt collector takes. With PayClaim, you can file a payment claim for a flat fee of just AUD $79.
4. Adjudication option: If the debtor contests the claim, you can escalate to fast-track adjudication within 10–21 days (depending on state), with a decision issued by an independent adjudicator.

The adjudication process is deliberately quick. Courts recognise that construction work happens on tight cash flow—tradies can’t wait 12 months for a judgment. An adjudicator reviews the claim, the response, and issues a binding decision in under three weeks.

Key Differences: Why the SOP Act Often Works Better

Let’s break down why many tradies see faster results with the Security of Payment Act than with debt collectors:

• Statutory right: The SOP Act is law. Debtors can’t ignore it like they ignore a collector’s letter. Many choose to settle or pay rather than face formal adjudication.
• No middleman commission: You keep 100% of what you recover. You’re not paying a collector 15% upfront.
• Built-in timeline: Everything happens within weeks, not months. The respondent knows they have 10 days to respond.
• Pressure without harassment: You’re using the law, not relying on a collector’s persuasion tactics.
• Works for service providers: Debt collectors often won’t touch smaller claims. The SOP Act works for any amount—$5,000 or $50,000.

One important note: if the debtor truly has no money, neither approach will magically make them solvent. But many debtors choose to pay or negotiate when they see a formal claim lodged under the SOP Act, because the alternative—a binding adjudication decision—carries real consequences for their business reputation and future credit.

When Debt Collectors Might Make Sense

That said, debt collectors aren’t useless. If you’ve already tried the SOP Act and received an adjudication decision, a collector can be useful for enforcement and recovery after the fact. Some debtors are repeat offenders or operate across multiple states, and a collector’s persistence might wear them down.

Debt collectors also work outside construction. If you’re chasing an unpaid personal loan or non-construction invoice, the SOP Act doesn’t apply, and a collector becomes more relevant.

But for construction invoices—payments for work done, materials supplied, or services rendered on a project—the SOP Act is the faster, cheaper, legal-backed option.

The Practical Path Forward

If you’re owed money in construction, here’s what most experienced tradies do:

1. Lodge a Security of Payment Act claim. It’s fast, cheap, and forces an immediate response.
2. Wait out the 10-day response window. Many debtors settle here to avoid adjudication.
3. If they contest it, proceed to adjudication. An independent third party decides within weeks.
4. Only if enforcement becomes necessary post-adjudication should you consider a debt collector.

The law is on your side. You don’t need to hand off your claim to someone else and lose a cut of your money. Start with the Security of Payment Act, use it as designed, and keep your recovery rate whole.

Unpaid invoices are frustrating. But you’ve got a faster weapon than most business owners realise.
