A Friday afternoon email arrives from a client you have worked with for two years. They say the report you delivered last month missed what they actually asked for, that they have had to pay another firm to redo parts of it, and that they are withholding your final invoice until "the matter" is resolved. You think the complaint is unfair: the scope of work changed mid-engagement, and the extra work was never agreed in writing.
This is one of the most common situations professional services firms face, and how you handle the first few weeks will largely decide how it ends. The financial exposure usually goes well beyond the unpaid invoice. A dissatisfied client can sue for breach of contract or professional negligence, and where the client is a consumer, they can rely on the consumer guarantees in the Australian Consumer Law (the ACL), including the guarantee that services are supplied with due care and skill. In some cases clients also allege they were misled about what they would receive, which engages the prohibition on misleading or deceptive conduct.
Two pressures make the early weeks decisive. The first is time. A claim for breach of contract or negligence must generally be brought within six years, and the clock can start running before you realise a dispute exists. The second is evidence. The emails, engagement letters and work product you already hold will decide the matter far more than anything either side says later. If you carry professional indemnity (PI) insurance, your policy will almost certainly require you to notify the insurer of circumstances that might give rise to a claim, usually as soon as you become aware of them. None of this means assuming the worst. It means acting methodically, in roughly the order below.
Steps to take when a client disputes your work
Review the engagement agreement before you respond
Your engagement letter or service agreement is the record of what you promised, what you excluded, how you charge, and what the parties agreed would happen if things went wrong. Read it before you write a single word back to the client.
- Scope of work: What were you engaged to deliver, and what was expressly excluded? Many disputes are really scope disputes, where the client expected work that was never agreed.
- Fee and payment terms: What did you agree about timing, milestones and what happens on late payment? This tells you what is actually owed while the dispute runs.
- Dispute resolution clause: Did you agree to attempt mediation or arbitration before court proceedings? If so, the client can hold you to it, and you can hold them to it.
- Limitation of liability: Does the agreement cap your liability or exclude certain loss? Note the limits of this: where the client is a consumer, you cannot contract out of the ACL guarantees at all.
That last point deserves care. A client is a consumer under the ACL where the services cost $100,000 or less, or are of a kind ordinarily acquired for personal, domestic or household use: see s 3 of the ACL in Schedule 2 of the Competition and Consumer Act 2010 (Cth). For those clients, s 60 implies a guarantee that services are rendered with due care and skill, and s 61 implies a guarantee that the services are reasonably fit for the purpose the client made known. Section 64 makes void any term that purports to exclude, restrict or modify those guarantees, so a "no liability" clause in your terms will not protect you against a consumer claim based on defective work. For business clients, the claim will usually be framed as breach of contract or negligence under the general law, where carefully drafted limitations of liability carry more weight.
Reply in writing, and preserve the record
Respond promptly and professionally, in writing. A complaint that is ignored, or answered with a defensive phone call that goes nowhere, hardens into a formal claim. Your reply should acknowledge the complaint, set out your understanding of the facts, and propose a way forward. It should not concede fault.
- What to gather: the engagement letter, emails and scope documents, drafts and final work product, invoices, and any notes of meetings or phone calls about changes to the work.
- What to avoid: admitting negligence in the heat of the moment, deleting or editing records, abusive or sarcastic replies, and promising free remedial work without first checking what it will cost you and what it will cover.
- What to clarify: whether the complaint is about defective work or about work the client expected but never approved. If you do agree to redo work, confirm in writing what is included and what is not.
If you are tempted to say nothing and hope the client moves on, remember that limitation periods run whether you respond or not, and most PI policies require notification even of complaints you consider groundless.
Notify your professional indemnity insurer
Most professional indemnity policies require you to notify the insurer of any claim, and of any circumstances that might give rise to a claim, as soon as you become aware of them. Late notification is a common reason insurers decline cover, and the decision to decline usually comes at exactly the moment you need the cover most. Notification is not an admission of fault. It is a condition of the policy, and it is the cheapest protection you will ever buy.
- What to notify: the complaint itself, the client's allegations, and any circumstances that suggest a claim is coming, such as a client demanding a refund or threatening to involve a regulator.
- What to include: copies of the complaint, the relevant engagement documents, and your timeline of events.
- What else to check: whether your professional body or regulator requires you to report complaints within a set period. Many professions do, and failing to report can be a separate disciplinary issue.
Keep a copy of everything you send the insurer, including the date. If the insurer asks for more information or directs you to appoint a lawyer, follow those directions.
Try negotiation and alternative dispute resolution
Most client disputes are settled without a court ever seeing them, and there are good reasons to make a genuine attempt to do so. Legal costs can quickly exceed the amount in dispute, and a negotiated outcome lets both sides keep control of the result rather than handing it to a stranger.
- Mediation: an independent mediator facilitates discussion between you and the client. The mediator does not decide anything, and the process is only binding if you both agree on a settlement. In New South Wales, courts can refer proceedings to mediation with or without the parties' consent: see s 26 of the Civil Procedure Act 2005 (NSW). Agreements reached at mediation can be converted into enforceable court orders under s 29 of that Act.
- Conciliation: similar to mediation, but the third party takes a more active role, evaluating each side's position and proposing solutions or compromises. The outcome is still only binding if both parties accept it.
- Arbitration: you and the client present your cases to an arbitrator who makes a decision. Unlike mediation and conciliation, that decision is binding. Under s 35 of the Commercial Arbitration Act 2010 (NSW), an arbitral award is recognised as binding and can be enforced through the courts. Arbitration suits disputes where the parties want a binding outcome but want it faster, cheaper and more private than court.
Courts in New South Wales are required to further the overriding purpose of resolving civil proceedings justly, quickly and cheaply, and parties have a duty to assist: see s 56 of the Civil Procedure Act 2005 (NSW). In practice, that means a party who unreasonably refuses to attempt ADR can face costs consequences even if they win the case. A genuine, well-documented attempt at negotiation or mediation is therefore not just good client relations; it protects your position on costs.
Treat litigation as a last resort
If the dispute cannot be resolved by discussion or ADR, litigation is the fallback. A court can make a binding, enforceable decision, which is what you want if the client is refusing to pay and no amount of talking will change their mind. But litigation is expensive, slow and public, and the outcome is unpredictable because the decision belongs to the judge, not to you.
- Time limits: a claim for breach of contract or negligence must generally be brought within six years of the cause of action accruing: see s 14 of the Limitation Act 1969 (NSW). If the client is threatening to sue, the deadline constrains them too, which is often a useful negotiating fact. If you are considering suing for unpaid fees, the clock runs against you, so do not let the dispute drift for years.
- Costs: the general rule is that the losing party pays the winning party's costs. That risk applies both ways, and it should focus both sides on settlement.
- Reality check: most proceedings settle before trial. A well-prepared case is often a prelude to a better settlement, not a guarantee of a hearing.
When to bring in a dispute resolution lawyer
You do not need a lawyer to have a difficult conversation with a client, and most disputes are best resolved without one. But there are points where professional help is worth the cost: when a formal claim is threatened, when your insurer asks you to, when the client involves a regulator or professional body, when settlement discussions stall, or when a limitation period is approaching and you need to know where you stand.
If you brought this situation to us, we would start by reviewing the engagement agreement, the correspondence and the work product to assess the strength of the client's claim and your exposure. We would check your PI policy and notification history, and advise on whether any further notification is needed. We would then help you decide between correcting the work, negotiating a settlement, or defending the claim, and we would draft any settlement agreement so that it includes a release of claims, confidentiality terms and a clear position on the unpaid invoice. If proceedings become necessary, we would run them, including the mediation that courts now expect before a matter reaches a hearing.
The first weeks decide the dispute
The counter-intuitive truth about client disputes is that the outcome is largely settled before the first legal letter is written. By the time a client complains, the engagement letter, the emails and the work product that will decide the matter already exist. The actions that create room to move are not dramatic: reading your own agreement, answering in writing, preserving the records and telling your insurer. The firms that skip those steps, or put them off while they argue with the client, are the ones that end up defending claims they could have settled, or paying for work they could have kept.
In short: review your engagement agreement before responding, reply in writing and keep records, notify your insurer of anything that might become a claim, attempt mediation, conciliation or arbitration before considering court, and treat litigation as the last resort. A client dispute is rarely pleasant, but handled methodically in the first few weeks, most are resolved without a courtroom.
