What Happens If a Builder Goes Silent on Your Invoice?

A builder who goes quiet on your invoice is one of the most stressful situations a subcontractor can face. You’ve done the work, submitted the invoice, and now — nothing. No payment, no response, no explanation. It’s frustrating, damaging to your cash flow, and often a sign of something more serious. Here’s what to do when a builder goes silent on your invoice.

Why Builders Go Silent

Before diving into what to do, it’s worth understanding why builders stop communicating about invoices. Common reasons include:

• Cash flow pressure: The builder is struggling to pay and hoping you’ll wait longer
• Financial difficulty: The builder may be in pre-insolvency territory — a serious red flag
• Dispute avoidance: They want to dispute your invoice but don’t want to commit anything to writing
• Simple disorganisation: In some cases, it’s genuinely poor accounts management
• Deliberate tactic: Some builders use silence to wear down subcontractors and push them toward accepting a reduced payment

The Legal Consequence of a Builder Going Silent

Here’s the critical point that most subcontractors don’t know: under Australia’s Security of Payment laws, a builder who fails to respond to a properly served payment claim faces serious legal consequences. If you serve a valid payment claim and the builder doesn’t respond with a payment schedule within 10–15 business days (depending on your state), the full claimed amount becomes a legally owed debt — and you can pursue it without going to court.

Silence is not a legal option for a head contractor who has received a properly served SOP payment claim.

Step 1: Stop Chasing Informally and Act Formally

The biggest mistake subcontractors make when a builder goes silent is continuing to send informal reminder emails and make phone calls. Stop. This approach doesn’t work with non-responsive builders and wastes time.

Instead, serve a formal payment claim under the Security of Payment Act applicable in your state. This is a different animal to a regular invoice or reminder — it’s a legal document that triggers specific statutory obligations on the builder.

Step 2: Serve a Payment Claim

A payment claim under the Security of Payment Act must be:

• In writing
• Identify the construction work it relates to
• State the amount claimed
• In most states, include a statement that it is made under the relevant SOP Act
• Served on the correct party in a legally valid way (personal service, registered post, or email where permitted)

Once the payment claim is served, the builder has 10–15 business days to respond. If they don’t — you win. The full amount is owed and you can apply to enforce it.

Step 3: If They Still Don’t Respond — Adjudication or Court

If the builder is served with a payment claim and still doesn’t respond with a payment schedule, you have two options depending on your state:

• Apply for adjudication: Fast, binding, typically 10 business days to a determination
• Go directly to court: In some states, you can recover an undisputed SOP debt directly through the courts without the adjudication step

What If the Builder Might Be Going Insolvent?

A builder who suddenly goes silent may be heading toward financial difficulty. If you see warning signs — other subcontractors are also unpaid, the builder is making excuses about “the developer not paying them,” the project has slowed significantly — act immediately. Every day matters if a builder is approaching insolvency. A Security of Payment determination obtained before insolvency is declared can significantly improve your position.
