Legal and financial recourse options for unpaid invoices and broken promises

A client owes you $18,000 for work you completed last month. The invoice went out on time, the work was done, and the client keeps promising payment "next week". After six weeks of that, you are no longer asking what the law says about being right. You are asking what you can actually do about it.

That is what recourse means in practice: the combination of legal rights and practical tools a business can use to recover money, enforce an obligation, or obtain a remedy when another party does not do what they promised. The range of options runs from a politely worded reminder letter through contractual enforcement, security interests registered on the Personal Property Securities Register (the PPSR), and formal court or tribunal action. This article sets out the options available to Australian small businesses, the limits the law places on them, and how to put stronger recourse in place before a dispute starts.

What recourse really is: rights, evidence and recoverability

Recourse is often described as the legal "path back" you have when something goes wrong. That description undersells how the system actually works. Recourse has three separate layers, and you need all three for it to be worth anything.

The first layer is the right itself. You have a right to payment when your contract or invoice creates one, a right to damages when the other side breaches, and a right to certain remedies under the Australian Consumer Law (the ACL) when you deal with consumers. The second layer is proof. A right you cannot evidence is a right you will struggle to enforce. The third layer is recoverability: whether the other party actually has money, assets, or an incentive to pay. A judgment against a company with no assets is a piece of paper.

A worked example shows how the layers interact. You supply fitted kitchen benchtops to a builder who has not paid the final $12,000 instalment. Your right to payment comes from the supply contract and the invoice. Your evidence is the signed order, the delivery dockets, and the emails approving the installation. Recoverability is the harder question: the builder's company may be a shelf company with no assets, which is why a personal guarantee from the director, signed at the start, matters. Each layer strengthens the others. A well-documented contract with a guarantee and a registered security interest converts "they owe me money" into a claim you can actually collect.

When recourse becomes a live issue

Recourse is not something you use only after a relationship collapses. It becomes relevant whenever a counterparty fails to perform, in any of these situations:

A customer does not pay: This is the most common trigger. Your options include late payment interest (if your terms provide for it), suspending further work, a formal demand, and court or tribunal proceedings.
A supplier delivers defective or late goods: You may have rights against the supplier under your supply contract, and your own customers may in turn have rights against you under the consumer guarantees if you sold the goods on.
A customer demands a refund: The ACL limits what you can do here, because your customers' rights are non-excludable and your refund signage and wording cannot mislead them about those rights.
A contractor or employee causes loss: Whether you have recourse against the individual depends on your contract terms, their duties, and what they actually did.
The other side becomes insolvent: A legal claim against an insolvent company competes with every other creditor for whatever is left, which is why security interests and guarantees matter.

The pattern across all of these is the same: the earlier you identify the risk and set expectations in writing, the more options you have later.

The contract levers you can pull

For most commercial disputes, your primary recourse runs through your contract. The starting point is that a properly formed contract, evidenced in writing, gives you a set of enforceable levers:

Interest and late fees on overdue amounts, but only if your terms actually provide for them. If your terms are silent, you cannot simply impose them.
Suspension of services for non-payment, where your terms allow it and where suspending does not itself breach the contract.
Termination for breach, subject to any notice periods and cure rights in your agreement.
Damages for losses the breach caused, provided the losses are not too remote and you can prove them.
Indemnities that shift particular risks, such as a customer's breach of your IP rights or a supplier's defective work, onto the party best placed to bear them.
Dispute resolution clauses requiring negotiation or mediation before litigation, which in practice resolve many disputes cheaply and quickly.

Your Terms of Trade is usually the document that carries these levers. It sets payment timing, what happens on late payment, delivery risk, limitation of liability, and the process for resolving disputes. A well-drafted set of terms does more for your recourse position than almost anything else you can do, because it converts operational assumptions into enforceable rights.

What the Australian Consumer Law limits

If you sell to consumers, the ACL shapes your recourse in ways that surprise many business owners, because it restricts what you can do to your customers rather than what they can do to you.

The consumer guarantees are the core of this. Goods supplied to a consumer must be of acceptable quality, fit for their disclosed purpose, match their description, and comply with any sample or demonstration model. Services must be provided with due care and skill. These guarantees cannot be excluded, restricted, or modified by contract: under s 64 of the ACL, any term that purports to do so is void. "No refunds" signage and warranty terms that say the statutory guarantees do not apply are both examples of the kind of wording that misleads consumers about their rights and exposes your business to regulatory action.

The remedies a consumer can demand depend on the size of the failure. If goods fail a guarantee but the failure can be remedied and is not a major failure, the consumer can require you to fix it within a reasonable time, and can have the failure remedied elsewhere, or reject the goods, if you refuse. If the failure is a major failure, or cannot be remedied, the consumer can reject the goods for a refund or recover compensation for the reduction in value, and can claim reasonably foreseeable loss in either case. The same structure applies to services under s 267 of the ACL, with termination of the contract as an additional option. Major failure is defined, not by dollar value, but by whether a reasonable consumer would have bought the goods knowing about the problem, whether the goods are substantially unfit for their common purpose, and whether they depart significantly from their description or sample. The ACCC's guidance for businesses sets out how these remedies operate in practice, including when a refund rather than a repair is required.

The other limit is the unfair contract terms regime. Under s 23 of the ACL, an unfair term in a standard form consumer or small business contract is void, and proposing or relying on such a term can attract pecuniary penalties. For these purposes a small business contract is one where at least one party employs fewer than 100 people or has turnover below $10 million in the last income year, so most small businesses are squarely within the regime. A term that creates a significant imbalance in the parties' rights and obligations, is not reasonably necessary to protect the legitimate interests of the party advantaged by it, and would cause detriment if applied, is unfair.

None of this stops you from enforcing payment from consumers. What it means is that your recourse strategy has two directions: how you recover from your debtors, and how you respond to your customers' claims in a way that keeps you compliant.

Security and asset-backed recourse

Sometimes the strongest recourse is not a lawsuit at all, but a mechanism that lets you recover value from assets if the other side defaults. Three tools dominate in small business:

Retention of title clauses: You retain ownership of goods until they are paid for in full, so if the customer defaults you can reclaim the goods rather than queueing as an unsecured creditor.
Personal guarantees: A director or individual guarantees the company's obligations, giving you recourse against a person with assets when the company has none.
Security interests registered on the PPSR: A general security agreement or a purchase money security interest (the PMSI) registered against the customer's assets gives you a claim to those assets ahead of unsecured creditors.

The PPSR is the national register of security interests in personal property established under the Personal Property Securities Act 2009 (Cth) (the PPSA), and getting the registration right is where most businesses come unstuck. Timing is the critical issue. Under s 55 of the PPSA, a perfected security interest has priority over an unperfected one in the same collateral, and if you sell goods on retention of title terms and fail to register, your interest can be lost to a later secured creditor or to a liquidator on insolvency. For a PMSI in goods that are not inventory, the interest must be perfected within 15 business days after the buyer obtains possession of the goods, per ss 62 and 63 of the PPSA. Miss that window and you lose the priority that makes the security worthwhile. Registration must also be accurate: a registration that describes the wrong collateral, or is registered against the wrong grantor, may be ineffective when you need it most.

Security interests are most valuable when the counterparty becomes insolvent, which is exactly when an unsecured creditor's claim is worth the least.

Payment structure as recourse

Much of the best recourse never involves a lawyer or a court. It is built into how you get paid:

Deposits before work starts, so a defaulting customer cannot leave you holding all the cost.
Milestone payments tied to stages of delivery, so your exposure tracks the work actually done.
Upfront payment for new or high-risk customers, with credit extended only once a payment history exists.
Tighter trading terms for repeat late payers, including shorter payment windows or COD.

Payment structure does not give you a legal remedy. What it does is reduce the size of the problem before it becomes one. A customer who owes you one milestone of $5,000 is a manageable dispute; the same customer owing you the full $60,000 project is not.

When the other side cannot pay

Insolvency changes everything, on both sides. If your customer is insolvent, your claim, however strong, becomes a proof of debt in their administration, competing with every other creditor. Against a company that owes you a debt of at least $2,000, s 459E of the Corporations Act 2001 (Cth) gives you a sharper tool: a statutory demand. If the company does not pay, secure, or compound the debt within the statutory period, it is presumed insolvent, which lets you apply to wind it up. The demand must be served in the prescribed form and is a step that should not be taken casually, because a defective demand can expose you to costs. A lawyer's input is advisable before issuing one.

The reverse risk is your own exposure. If your business is owed money and one of your own creditors serves a statutory demand on you, or your customers stop paying, the same machinery can be pointed at you. Cash flow pressure from a single large default is a common pathway into insolvency for small businesses. That is why the tools in this article are risk management as much as dispute resolution: deposits, security, guarantees, and early escalation all exist to stop one unpaid invoice from becoming an existential problem.

Building recourse into your business before you need it

Every tool above is easier to deploy if it was set up before the dispute started. The practical work is:

Put the documents in place: Customer contracts, Terms of Trade, supplier agreements, and website terms that reflect how you actually do business. A contract that describes a different process to the one you run is worse than none, because it will not survive scrutiny.
Tighten the paper trail: Signed quotes and scopes of work, written variations, invoices that match milestones, delivery confirmations, and a record of complaints and how you responded. Disputes are won on documents, not on recollection.
Treat credit as a deliberate decision: Set credit limits, use shorter terms for new customers, ask for director guarantees in higher-risk relationships, and register security interests where the exposure justifies it.
Write dispute clauses that help: Mandatory negotiation or mediation before litigation, clear timeframes for raising issues, and defined exit and termination steps keep disputes fast and commercial.

None of this prevents every dispute. What it does is ensure that when one happens, you are choosing between enforcement options rather than discovering that you have none.

Using recourse when something goes wrong

When a counterparty defaults, the sequence that most often works is:

Identify the exact right and the breach: What was agreed, what obligation was breached, and what remedy the agreement provides.
Decide the outcome you want: Getting paid in full, a fast partial settlement, or a clean exit are different goals that point to different strategies.
Escalate in writing, factually: A professional demand that references the agreement, the amount, and the supporting documents resolves many disputes without proceedings. Threats and abuse do the opposite.
Assess whether the other side can pay: Before spending on proceedings, look at their assets, whether they are trading, and what recovery would realistically look like.
Act before your position weakens: Accepting defective performance, granting extensions informally, or making admissions can erode rights you thought you had.

For smaller debts, state and territory tribunals offer a lower-cost path than the courts, and for debts against companies, the statutory demand regime sits alongside them. The right forum depends on the amount, the identity of the debtor, and the nature of the claim.

When you need a lawyer, and what one actually does

Much of what this article describes you can do yourself: standard demand letters, tribunal applications for straightforward debts, and disciplined record keeping. The judgement calls are where a commercial lawyer earns their fee:

Drafting the documents that create recourse, including Terms of Trade, retention of title clauses, guarantees, and security agreements, so the rights exist in enforceable form.
Advising on PPSR registration before the 15-business-day PMSI window closes, and checking registrations before you rely on them.
Assessing whether a claim is worth pursuing, including the recoverability question the article cannot answer for you, because it depends on the other side's circumstances.
Issuing a statutory demand or responding to one, where form and timing are strictly prescribed and mistakes are costly.
Choosing the right forum and managing the claim, including the evidence a court or tribunal will actually weigh.
Navigating consumer law exposure, so your response to a customer claim does not itself breach the ACL.

The value of early advice is not legal fireworks. It is that a lawyer reviews your contract position before you send the letter that inadvertently waives a right, or before the limitation period quietly runs out.

The sharpest point: enforceability and recoverability are different things

The mistake that costs businesses most in disputes is assuming that a strong legal position is the same as money in the bank. It is not. Enforcement is a process with costs, delays, and procedural traps, and it only ever delivers what the other side can actually pay. The businesses that come through disputes intact are the ones whose recourse was designed before the relationship started: registered security, signed guarantees, deposits, and documentation that matches reality. If you are reading this after a default, the question to answer now is not whether you are right, but what evidence you hold, what the other side owns, and which of the levers above you actually have.

In summary: recourse is the set of legal rights and practical tools available when a counterparty fails to perform, from contractual enforcement and ACL remedies to PPSR security, payment structures, and statutory demands. Your strongest recourse comes from clear contracts and good records set up in advance. If you are already in dispute, act early, document everything, and get advice before you commit to a path that weakens your position.
