Concreters: Three Tactics That Beat Slow-Paying Builders

You’ve finished the slab. The job looks good. The builder’s happy. But three weeks later, your invoice still hasn’t moved past “we’ll process it next week.”

Slow-paying builders aren’t a personality flaw—they’re a cash flow problem. And it becomes your problem the moment they owe you money.

If you’re a concreter tired of chasing payment, here are three tactics that actually work. None of them require you to hire a lawyer or wait months for action.

Tactic 1: Lock Down Your Terms Before the Work Starts

This sounds obvious, but most tradies skip it. Before you pour a single cubic metre, you need a written agreement that spells out:

• Payment due date (e.g., 7 or 14 days, not “net 30” which builders will ignore)
• What triggers payment (completion of the concrete, practical completion of your section, or final inspection)
• Late payment interest (standard in construction is 10% per annum)
• Your right to suspend work if payment falls overdue

A simple one-page quote or contract email signed before work starts is enough. It becomes evidence later if you need it.

Why this matters: Builders test boundaries. If there’s no written date, they’ll assume they can pay when they feel like it. If there’s a date in writing, they know you’re serious.

Tactic 2: Issue a Formal Payment Claim Under the SOP Act

This is where your legal teeth come in—and it doesn’t cost much or take long.

Every Australian state has a Security of Payment (SOP) Act designed specifically for situations like yours. NSW has the Security of Payment Act 1999, Queensland the Building Industry Fairness Act 2017, Victoria the Security of Payment Act 2002, and so on. These laws exist to stop builders from sitting on invoices forever.

Here’s how it works in plain terms:

1. You issue a formal payment claim (within the timeframe set by your state’s Act—usually within a few weeks of completing your work)
2. The builder has a set number of business days to respond with a payment schedule or dispute notice (usually 5–10 business days, depending on the state)
3. If they don’t respond, or if they dispute unfairly, you can apply for fast-track adjudication
4. An adjudicator decides the claim quickly—often within 2–4 weeks of lodgement
5. The builder must pay the adjudicated amount, even while they dispute it further

The key: this process is designed to be fast and accessible to tradies without lawyers. You don’t need a law degree to use it.

If you’re not sure how to draft a compliant payment claim for your state, or want to lodge one without the headache, you can file a payment claim through an online service that handles the paperwork.

Many builders know about the SOP Act and what it can trigger. Once they see a formal claim, the dynamic often shifts. They know you’re not going away, and they know adjudication costs them time and money.

Tactic 3: Know Your Right to Suspend Work

If a builder owes you money and refuses to pay, you can stop work. This is a legal right under the SOP legislation in every state, but only if you follow the rules.

Typically, you must:

• Give written notice of non-payment (email is fine)
• Allow a set period for the builder to respond (usually 5–10 days)
• Then you can suspend work without breaching the contract

This isn’t about walking off the job in anger. It’s a formal, documented step that forces a conversation.

Once a builder realises you’re serious enough to stop work—which costs them more than paying you—the speed of payment often changes overnight. Practical completion delays, punch-list items stop moving, and project financing can be jeopardised. They feel the pain faster than you do.

Write the suspension notice clearly, keep a copy, and be ready to restart the moment payment clears.

What Stops Most Tradies? Inaction.

The worst response to a slow-paying builder is silence. Waiting for them to remember you, or hoping they’ll call, is a losing game.

Builders count on subcontractors being tired, under-resourced, and reluctant to cause a fuss. That’s how invoices sit unpaid for months.

The moment you issue a formal payment claim or send a suspension notice, you stop being a passive creditor. You become someone with a deadline, a process, and teeth.

Your state’s SOP Act was written so you didn’t need a lawyer to use it. The process is self-service, it’s affordable, and it works because it’s backed by law.

Next time a builder’s payment stalls, pick one of these three tactics. Better yet, use all three: lock down terms upfront, issue a formal claim if they don’t pay, and be ready to suspend if they ignore the claim.

That’s how concreters who get paid do it.
