Landscaping Contractors: Recovering Unpaid Invoices the Smart Way

If you’ve completed landscaping work and your invoice has gone unpaid for weeks or months, you’re not alone. Plenty of landscaping contractors and subcontractors get stuck chasing payment from builders, developers, and head contractors who drag their feet. The frustration is real—you’ve done the work, your team’s time is out of pocket, and you still need to pay your suppliers and wages.

The good news? Australia’s Security of Payment legislation exists specifically to help tradies like you recover unpaid invoices without waiting years for court action. It’s a faster, cheaper pathway designed for the construction industry.

What Is Australia’s Security of Payment Legislation?

Every Australian state has its own Security of Payment (or Building and Construction Industry Payments) legislation. In NSW, it’s the Security of Payment Act 1999. Queensland has the Building Industry Fairness (Security of Payment) Act 2017. Victoria uses the Security of Payment Act 2002. Each state’s rules are slightly different, but they all do the same thing: they give construction subcontractors a fast-tracked way to recover unpaid invoices.

Instead of suing in court (which takes years and costs thousands), you can lodge a payment claim and, if the head contractor doesn’t respond properly, apply for adjudication. An adjudicator—a neutral third party—makes a binding decision within days, not months.

The key point: these laws apply to landscaping work. If you’re a subcontractor or contractor in the construction chain and you’ve invoiced for landscape design, installation, maintenance, or earthworks, you’re likely protected.

The Payment Claim: Your First Move

A payment claim is a formal notice to the person who owes you money (the “respondent”). It sets out:

• What work you did and when
• The invoice amount and what it covers
• The due date and how much is still unpaid
• A deadline for the respondent to respond (usually 10 business days)

This isn’t a casual email or follow-up call. A payment claim is a legal document that triggers the SOP process. Once issued, the respondent is required to either pay you or issue a formal payment schedule explaining why they won’t pay in full and when they will.

Here’s the thing: many debtors choose to pay or settle rather than face fast-track adjudication. A payment claim signals you’re serious and you know your rights. It often shifts the conversation from “we’ll pay you when we feel like it” to “let’s sort this out.”

The process varies slightly by state. In NSW, the respondent has 10 business days to issue a payment schedule. In Queensland, it’s also 10 business days. In Victoria, it’s the same. Check your state’s rules, but the principle is consistent: short deadlines, tight rules, no room for dodging.

What Happens If They Don’t Respond?

If the respondent doesn’t issue a payment schedule within the deadline, you move to the next step: adjudication.

Adjudication is a fast-tracked dispute resolution process. You lodge an adjudication application (along with your payment claim and evidence), and an independent adjudicator is appointed. They review both sides’ arguments and issue a determination.

The whole process typically takes 21 days from application to determination. That’s orders of magnitude faster than court.

Once the adjudicator makes a determination in your favour, the respondent is legally required to pay. If they don’t, you can enforce the determination through the courts—but enforcement is usually straightforward because the adjudicator has already made the call.

Key Steps to Follow

Getting your payment claim and adjudication right is critical. Here’s the practical sequence:

1. Document everything. Gather invoices, delivery dockets, photos, email correspondence, and any variation orders. The clearer your evidence, the better.
2. Identify the correct respondent. Work out who in the contract chain owes you money. It’s usually the head contractor or the builder you directly invoiced.
3. Prepare your payment claim. Set out the work, the amount, and the due date. Be factual and clear. Don’t overstate or include disputed items you can’t prove.
4. Serve the claim formally. Most states require personal delivery, email, or post to a specified address. Hand-delivery or leaving it on site doesn’t cut it.
5. Wait for their response. If they issue a payment schedule, review it. If they don’t respond and the deadline passes, move to adjudication.
6. Lodge an adjudication application if needed. Include your payment claim, evidence, and a brief explanation of why they’ve breached SOP requirements.

The paperwork can feel overwhelming if you’ve never done it before. That’s why many landscaping contractors file a payment claim using a self-service platform that walks through the process step by step—it’s faster than doing it from scratch, and it ensures you don’t miss critical deadlines or formatting rules.

Common Mistakes to Avoid

Don’t include GST twice. Don’t claim for work you can’t prove with documents. Don’t serve the claim to the wrong person or address. Don’t wait too long before acting—there are timeframes for when you can lodge a claim after the work is done, and they vary by state. In most states, you can claim within a reasonable time, but don’t leave it years.

Also, don’t assume the respondent will ignore you. Many builders take payment claims seriously because they know adjudication is real and binding. The leverage is there.

Get Your Money Back On Track

Unpaid invoices drain cash flow and put pressure on your team. Australia’s Security of Payment laws give you a practical, fast way to recover what you’re owed without hiring lawyers or spending months in court. Whether you’re a solo landscaper or running a small contracting business, these laws are there to protect you.

Start by gathering your documents, identifying the respondent, and preparing your claim. Know your state’s Act—it matters. And if the process feels complex, remember that the system is designed to be accessible to tradies, not just lawyers.

Don’t let unpaid invoices become your problem. Take action, follow the rules, and get back to work.
