You are about to sign a contract in which one specific failure would hurt your business. The project has a completion date, the software has an uptime commitment, the supplier has a delivery window. On the table, or in your template, is a line that fixes what the other side pays if that date slips: a daily rate, an agreed amount, a credit against future invoices. You need to decide whether that line belongs in the contract at all.
The real question is not whether liquidated damages clauses exist. It is whether this contract should pre-price one foreseeable failure with an agreed amount, or leave the loss to be proved later if the failure happens. You have three realistic options. The first is a liquidated damages clause, which fixes a sum or formula, usually a daily rate or a percentage, payable when a defined trigger occurs such as late completion or a missed service level, typically capped at a percentage of the contract price. The second is service credits, common in managed services, which accrue as credits against future invoices rather than cash payments. The third is no special term at all, so the ordinary remedy for breach applies and you prove your loss to a court if the failure ever happens.
One of these options looks more attractive than it is. A clause drafted to punish, with a figure plucked from the air, is likely to be struck down as a penalty, and an unenforceable liquidated damages clause can leave you worse off than no clause at all. The counterparty has priced the risk into the deal, but you cannot rely on the agreed amount and must prove your loss the hard way. Service credits attract the same penalty analysis even though they are not cash payments. So the "should I include it" decision and the drafting decision are really the same decision, and the factors below are the ones that settle it.
What to weigh up
Can you price the failure in dollars now?
A liquidated damages clause earns its place when the failure has a cost you can estimate in advance. If a late completion costs you a predictable amount per day, a daily rate gives both sides certainty from day one. The costs that usually justify a rate include:
- Stand-down costs: staff or plant you keep paying while a project is stalled.
- Lost revenue or rent: income you forgo for each day premises, equipment or software is unavailable.
- Financing costs: interest on capital tied up longer than planned.
- Customer penalties: damages you owe your own customers because you are late.
- Temporary cover: extra staff or equipment hired to bridge the gap.
If the loss is highly variable, hard to predict, or small, the clause adds negotiation and administration without much benefit, and ordinary breach rights may serve you better. Reserve the clause for the few failures that matter most rather than every obligation in the agreement. A clause that tries to price every breach quickly becomes unmanageable and, worse, starts to look punitive.
Can the amount survive the penalty rule?
This is the heart of the decision. Australian law distinguishes a genuine pre-estimate of loss from a penalty, and only the first is enforceable. In Andrews v Australia and New Zealand Banking Group Ltd (2012) 247 CLR 205, the High Court held that the penalty doctrine is not confined to clauses triggered by a breach of contract; it can also reach fees payable on the occurrence of other events that a party was obliged to avoid. In Paciocco v Australia and New Zealand Banking Group Ltd (2016) 258 CLR 525, the Court confirmed the modern test: a stipulated sum is a penalty if it is out of all proportion to the legitimate interest of the party in performance of the primary obligation. The comparison is made as at the time the contract is signed, not with the benefit of hindsight about what actually happened later.
An important nuance follows from Paciocco itself. The amount does not have to match the loss dollar for dollar. The bank's late payment fees of $35 and $20 survived even though the direct cost of a late payment was around $3, because deterring late payment and covering the bank's broader costs were legitimate interests. Compensation is not the only interest the law protects. But a figure that is extravagant or unconscionable compared with the greatest loss reasonably foreseeable at signing is a red flag. The practical contrast looks like this:
- A defensible rate: a daily amount built from a written estimate of your costs, capped, and time-limited, with the rationale recorded in the file at signing.
- An indefensible rate: a round number chosen to "keep them honest" or copied from a template, with no link to likely loss and no cap.
There is a second enforceability overlay for standard form contracts. Under s 23 of Schedule 2 to the Competition and Consumer Act 2010 (Cth) (the Australian Consumer Law or ACL), an unfair term in a standard form consumer contract or small business contract is void. A contract is a small business contract where at least one party employs fewer than 100 people or had turnover under $10 million in its last income year (s 23(4) of the ACL). A term is unfair if it would cause a significant imbalance in the parties' rights, is not reasonably necessary to protect the other party's legitimate interests, and would cause detriment (s 24 of the ACL). Since 9 November 2023, proposing or relying on an unfair term in a small business standard form contract is itself a contravention attracting pecuniary penalties (ACL s 23(2A) and s 224). The maximum for a body corporate is the greatest of $50 million, three times the benefit obtained, or 30 per cent of adjusted turnover, and $2.5 million for an individual, as the ACCC has confirmed. A liquidated damages clause that is disproportionate is exactly the kind of term that can be challenged on this ground as well.
Does the size and risk of the deal justify the machinery?
A liquidated damages regime needs supporting mechanics: notice obligations, measurement and reporting of the trigger, invoicing, audit rights, extensions of time, and cure periods. On a large, long-term or critical-path engagement, that machinery pays for itself. Construction completion dates, technology implementations with go-live milestones, data centre uptime targets and manufacturing delivery schedules are the classic settings. On a short, low-value or highly variable engagement, the clause and its mechanics can cost more than the risk they manage.
There is also a commercial reality to weigh. A supplier facing a one-sided clause will price the risk into the quote, so the "free" protection is often paid for in the price. If the deal is genuinely low risk, a clear statement of delivery dates and service levels, backed by ordinary breach rights, may be enough.
Does the clause fit your broader liability framework?
A liquidated damages clause never operates alone. It sits inside a risk allocation framework made up of caps, exclusions, indemnities and termination rights, and the drafting needs to make the connections explicit:
- The overall cap: decide whether the contract's general limitation of liability cap applies to liquidated damages and say so. A cap in the range of 10 to 20 per cent of the contract price is common commercial practice, but the figure should be negotiated for the deal, not copied.
- Consequential loss: if the liquidated damages are intended to capture losses the consequential loss exclusion would otherwise block, such as revenue lost during downtime, say that in the clause so there is no double counting and no unintended carve-out.
- Sole remedy or not: decide whether liquidated damages are the exclusive remedy for the trigger event or whether other losses can also be claimed, and state it. A common structure makes liquidated damages the sole remedy for delay while preserving general remedies for other breaches.
- Accrual and set-off: fix when damages stop accruing, for example on termination, and whether accrued amounts can be set off against invoices, consistently with any set-off clause in the agreement.
Which side of the table are you on?
Your negotiating priorities depend on your position in the deal:
- If you are the buyer or principal: you want the rate tied to your real costs, transparent calculation, reporting and audit rights, notice mechanics, and a cap high enough to keep the supplier motivated.
- If you are the supplier or contractor: you want a realistic cap, carve-outs for events outside your control such as force majeure and customer-caused delay, cure periods, extensions of time for approved variations, and the clause limited to a narrow list of triggers so it does not overlap with other remedies.
Both sides should push for clarity on whether service credits or liquidated damages are the exclusive remedy for service-level failures, because that is where disputes about double recovery start.
How an Artificer Legal lawyer helps you make and act on the call
Most of this decision turns on a judgment about proportionality that is easy to get wrong in practice. An Artificer Legal practitioner can help in specific ways:
- Stress-test the rate: model what a court would treat as out of all proportion, and pressure-test your estimate against the greatest loss reasonably foreseeable at signing.
- Check the enforceability overlays: confirm the clause is a genuine pre-estimate rather than a penalty under the Andrews and Paciocco line of authority, and, for standard form contracts, whether it could be an unfair term under the ACL with the penalties that now attach.
- Map the clause against the rest of the contract: align triggers, caps, exclusions, indemnities, set-off and termination rights so the document works as one framework rather than a collection of conflicting lines.
- Draft the mechanics: define triggers precisely, build in extensions of time, cure periods, reporting and notice requirements, and record the written rationale for the rate in the file.
- Negotiate from your side: whether you are buyer or supplier, having the drafting logic ready changes the negotiation, because the other side's lawyer will test the number too.
Start from a rate you can defend
The decision is really about one thing: whether you can justify the figure in writing at the date of signing. Courts assess proportionality at the time the contract is made, on the information available then, not in hindsight. If you can tie the rate to a documented estimate of your loss, cap it, and align it with the rest of the contract, a liquidated damages clause is a genuinely useful piece of risk management. If you cannot defend the number, you are better off leaving the clause out and relying on ordinary damages, because a clause that fails as a penalty gives you the worst of both worlds: the risk priced into the deal, and no agreed remedy to rely on when the failure happens.
To recap the Australian position: a pre-agreed sum for a specific failure is enforceable when it is a genuine pre-estimate of loss and not a penalty, with the modern test focused on whether the amount is out of all proportion to the innocent party's legitimate interest in performance; the clause needs clear triggers, a defensible rate, a cap and accrual limits; it must fit consistently with the contract's overall liability cap, consequential loss exclusion and set-off rights; service credits are a practical alternative in managed services but attract the same analysis; and for standard form consumer or small business contracts, an unfair clause can now attract substantial penalties. Where that judgment is close, it is exactly when a commercial lawyer's review earns its fee.
