How to recover an unpaid B2B invoice in Australia

Recovering an unpaid B2B invoice in Australia runs through a fixed sequence: a letter of demand, then a statutory demand or a court claim if the debtor stays silent, then enforcement against assets once a judgment exists. Each step has a point where continuing costs more than it recovers.

When this route applies and when it does not

This process fits an undisputed invoice owed by an Australian business for goods or services delivered as agreed. The debtor has not raised a genuine quality or delivery complaint. It does not fit a contract dispute, a claim the debtor is actively contesting on the facts, or a debtor already in external administration – those go to litigation strategy or an insolvency claim, not straight recovery.

Whether the debtor is a registered company or a sole trader changes the toolkit. A statutory demand exists only against a company incorporated under the Corporations Act. Against an individual trader, the equivalent lever runs through personal insolvency procedure or a direct court claim, not a statutory demand.

A separate question is whether you already hold a judgment from a court outside Australia and want it enforced against an Australian debtor. That is a different track, closer to enforcing a foreign judgment against an Australian debtor than to the domestic recovery sequence below.

The sequence

The stages below assume a domestic Australian debtor and an unpaid invoice with no genuine dispute on the facts.

  1. Letter of demand. You need the invoice, the contract or purchase order, proof of delivery or performance, and confirmation of the correct legal debtor entity. Send a letter of demand with a fixed payment deadline. The debtor can pay, propose a payment plan, dispute the debt, or ignore the letter entirely.
  2. Statutory demand or bankruptcy notice equivalent. If the debtor is a company and the debt is undisputed, a statutory demand puts a short, fixed clock on the debtor: pay, negotiate, apply to have the demand set aside, or face a presumption of insolvency. Against a sole trader the practical lever is a court claim rather than this instrument.
  3. Court claim. If the demand stage produces nothing, the next step is lodging a claim in the court or tribunal that matches the amount and the state or territory where the debtor is based. That involves the local court claim process for a small business invoice. The debtor can defend the claim, ignore it and let a default judgment issue, or settle before a hearing.
  4. Judgment enforcement. Once judgment is entered and still unpaid, enforcement options include examination of the debtor's financial position, garnishee orders against a bank account or wages, and, for a company, a winding-up application. The debtor can still pay, negotiate, or, if it is a company, be placed into voluntary administration or liquidation to stop individual enforcement.

What drives the cost and the time

Cost and time both scale with how far the file has to travel. A letter of demand that produces payment is the cheapest and fastest outcome by a wide margin. Every escalation past it – demand, claim, enforcement – adds filing steps, waiting periods set by the court calendar, and the chance the debtor contests rather than complies.

Which state or territory the debtor sits in matters, because court procedure and filing practice differ between them. Whether the debtor is a company or an individual matters too: a statutory demand only threatens a company with the presumption of insolvency, so it carries less weight against a sole trader.

The debtor's asset position is the real variable behind enforcement time. A judgment against a company with no traceable assets and no trading activity is a piece of paper. In that situation, and only where the debtor structure supports it, the more useful question shifts to personal liability of the company's director rather than further enforcement against an empty shell.

The decision point

Before moving from a letter of demand to a statutory demand or a court claim, weigh the invoice value against the cost of the next step and against what you actually know about the debtor's ability to pay. A debtor that went silent because it has no funds behaves very differently from one that went silent because the invoice sat in the wrong inbox.

This is also the point to separate a genuine dispute from a stalling tactic. If the debtor raises a real quality or delivery objection for the first time only after the demand, the file stops being a recovery matter and becomes a contested claim, with a different cost profile. Structured debt recovery services in Australia exist precisely to make that call before money is spent on the wrong track.

When to stop

Stop, or at least pause, in three situations. First, the debtor company has already been deregistered or placed into liquidation with no fund available for unsecured creditors – further steps against the company itself recover nothing. Second, the invoice value is lower than the combined cost of a statutory demand, a court claim, and enforcement, leaving no margin even on a full recovery. Third, the debtor mounts a genuine, substantive dispute that would need a full trial to resolve – at that point you are buying litigation, not recovery, and the decision needs a different kind of cost-benefit analysis.

A short cost and time estimate before you file at this stage tells you which of the three situations you are actually in, before the next invoice for fees arrives.

Common questions

How long does it take to recover an unpaid B2B invoice in Australia?

It depends on where the file stops. A letter of demand that produces payment resolves in weeks. A statutory demand or a court claim that the debtor contests, followed by enforcement, takes considerably longer, and the timeline is set as much by the debtor's response as by the process itself.

Can I recover an unpaid invoice in Australia without going to court?

Often, yes. A well-documented letter of demand, and against a company a statutory demand behind it, resolves a large share of undisputed invoices without a court claim ever being filed. Court becomes necessary only once the debtor ignores both or formally disputes the debt.

What happens if the Australian debtor ignores a letter of demand?

Ignoring the letter does not stop the process; it moves the file to the next stage, typically a statutory demand for a corporate debtor or a court claim. Silence is treated as a decision not to engage, and the creditor decides whether the invoice value justifies escalating.

The invoice sat unpaid while the shipment already went out, and every week of silence from the Australian buyer looks less like an oversight and more like a queue you are not first in. The sequence above exists so the next dollar spent chasing it goes to the step that actually moves the debtor, not the one that simply feels like progress.
