As a small business owner, you’re probably juggling product quality, customer expectations, suppliers, cash flow and (somehow) still trying to grow. The tricky part is that even when you do “everything right”, you can still end up with a customer complaint saying your goods or services were not fit for purpose.
This phrase comes up a lot in Australia because it sits at the heart of the consumer guarantees under the Australian Consumer Law (ACL). If you sell products, run an online store, provide services, or manufacture anything (even indirectly through suppliers), understanding when something may be “not fit for purpose” is one of the most practical legal risk-management steps you can take.
In this guide, we’ll break down what “not fit for purpose” means, what customers can demand when something goes wrong, and how you can protect your business through clear contracts, warranty settings, and sensible internal processes.
What Does “Not Fit For Purpose” Mean In Australian Consumer Law?
“Not fit for purpose” is a consumer guarantee concept. In plain English, it means the product (or service outcome) isn’t suitable for the purpose it was meant to be used for.
Under the ACL, goods must generally be fit for:
- all the common purposes you’d normally expect those goods to be used for, and
- a particular purpose the customer made known to you (expressly or by implication), as long as they relied on your skill or judgment.
So, a not fit for purpose complaint often isn’t about whether the item is completely broken. It can be about whether it does the job a reasonable person would expect it to do, based on what it is and what was said about it.
For example, your customer might say an item is not fit for purpose if:
- it can’t perform the basic function it’s normally meant to perform (even if it technically “works”)
- it performs that function in a way that’s unsafe, unreliable or unreasonably short-lived
- it was recommended for a specific use, but fails in that use
If your business sells goods to consumers (including online), this is closely tied to the ACL guarantee that goods are of acceptable quality and fit for purpose. The concept is explained further in section 54 (which is one of the key ACL provisions small businesses end up dealing with in day-to-day operations).
Does “Not Fit For Purpose” Apply To Services Too?
Yes. While “fit for purpose” is often discussed for goods, service providers can face similar issues through the service consumer guarantees - including that services are provided with due care and skill, and (where relevant) are fit for a particular purpose or achieve a stated result (see ACL s61).
Think of services like:
- installation services
- repairs and maintenance
- custom manufacturing or fabrication
- professional or creative deliverables (depending on the scope promised)
If you promise a particular outcome (or your customer relies on you for a purpose), your service delivery needs to align with that.
When Is Something Considered Not Fit For Purpose (Common Small Business Scenarios)?
Most disputes about something being not fit for purpose happen because expectations weren’t aligned upfront, or because the product wasn’t suitable for how the customer planned to use it.
Here are some common scenarios we see in small business sales:
1. The Customer Told You What They Needed, And You Confirmed It
If a customer says, “I need this to do X”, and you confirm the product will do X (or you recommend a particular option), it increases the chance that “fit for purpose” is measured against that specific use.
This is particularly common with:
- specialised equipment
- trade tools
- health/wellness products
- business-to-consumer tech products
2. The Listing Or Advertising Creates A Clear Expectation
Even if a customer never spoke to you directly, your website copy, product descriptions, packaging and ads can set expectations about what the product will do.
This is why it’s important your marketing doesn’t accidentally cross the line into misleading representations. If you’re reviewing your advertising claims and product descriptions, it can help to keep misleading or deceptive conduct risks in mind.
3. The Product Works, But Not In A “Reasonable” Way
A product might turn on and operate, but still be considered not fit for purpose if it fails too quickly, can’t perform consistently, or isn’t safe.
In other words, it’s not just about “defective vs not defective” - it’s about whether it’s suitable for the intended use when assessed objectively.
4. The Customer Misused The Product (And You Have Evidence)
Not every complaint will result in your business being responsible.
For example, if goods fail because a customer used them in a way that was clearly not intended (and your instructions and warnings were clear), that can change the analysis.
From a practical point of view, the key is documentation: instructions, warnings, product specifications, and records of what was said at the point of sale.
Warranties And Remedies: What Does The Customer Actually Get If It’s Not Fit For Purpose?
When a customer complains that goods are not fit for purpose, the next question is usually: what do we have to do about it?
Under the ACL, the answer depends on whether the issue is a:
- major failure, or
- non-major failure.
The classification matters because it affects what remedies the customer can insist on.
Major Failure vs Non-Major Failure (Why It Matters)
While the ACL definitions are technical, a helpful way to think about it is:
- Major failure: the problem is serious enough that the customer wouldn’t have bought it if they’d known, or it’s unsafe, or it can’t easily be fixed within a reasonable time.
- Non-major failure: the problem can be fixed in a reasonable time (for example, repair, replacement, or remedying the service outcome).
If there’s a major failure, customers may be entitled to:
- a refund, or
- a replacement, or
- compensation for certain losses (depending on circumstances).
If the failure is non-major, you may be able to choose the remedy (for example, repair or replacement) as long as it is done within a reasonable time.
What About “Warranty Periods” Like 12 Months or 2 Years?
A common misconception is that your store’s warranty policy is the only thing that matters.
In Australia, consumer guarantees can apply regardless of a manufacturer warranty, store policy, or “warranty expired” message - depending on what is reasonable for the type of product and its expected lifespan.
This is why small businesses should be careful about making blanket statements like “we only offer a 12-month warranty” without understanding ACL minimum guarantees. If you want a plain-English explanation of how the “2-year warranty” concept is often misunderstood, the article on ACL warranty timeframes is a helpful reference point for the practical issues businesses face.
Warranties Against Defects (Optional, But Risky If Done Wrong)
Some businesses provide an additional “warranty against defects” (a promise that goes beyond consumer guarantees). This can be a great trust-builder - but it needs to be drafted carefully and include mandatory wording.
If your business wants to offer an extra warranty (for example, “we’ll replace within 24 months”), it’s worth ensuring you use a compliant Warranties Against Defects Policy so you don’t accidentally create obligations you can’t meet or trigger compliance issues.
How To Reduce “Not Fit For Purpose” Disputes Before They Start
Most not fit for purpose disputes don’t begin with a customer trying to be difficult. They usually start with unclear communication and mismatched expectations.
Here are practical steps you can take (without making your customer experience clunky):
1. Be Clear About What The Product Or Service Does (And Doesn’t Do)
Your product pages, quotes and invoices should be consistent.
If there are limitations (for example, compatibility requirements, environmental conditions, maintenance requirements, “not suitable for commercial use”, “not waterproof”), make them obvious upfront.
One simple practice is to add a short “Suitable for / Not suitable for” section on product listings, proposals or service scopes.
2. Document What The Customer Asked For
If a customer explains a specific purpose in writing (email, order form, CRM notes), keep those records.
This helps in two ways:
- it reduces misunderstandings (your team can confirm the right product/service scope), and
- it gives you evidence if there’s later a dispute about what was actually requested and promised.
3. Train Staff Not To Overpromise
Sales conversations are a major source of “fit for purpose” reliance.
You don’t need your staff to become lawyers, but you do want them to understand a simple principle: if you say it will do something, you may be held to it.
Consider a simple internal rule: if a customer asks, “Will this work for X?”, the team should either confirm based on specs, or qualify the answer and suggest the customer double-check suitability.
4. Use Plain-English Terms And Conditions
Well-written customer terms can help you:
- define the scope of what you’re supplying
- set expectations around delivery, installation, and timeframes
- create a clear complaints and returns process
- reduce arguments about “what was included”
For product-based businesses (especially B2B), properly drafted Terms Of Trade can also be a key tool to manage credit risk and disputes - while still respecting what you can’t exclude under the ACL.
Contract Protections: What You Can (And Can’t) Limit When “Not Fit For Purpose” Comes Up
A lot of small businesses ask: “Can’t we just put something in our terms that says we’re not liable?”
The reality is:
- for consumer sales covered by the ACL, you generally cannot contract out of consumer guarantees
- for non-consumer/B2B supplies, you may be able to limit certain guarantees and liability in specific circumstances (for example, where ACL s64A applies), but it depends on the type of goods/services, who you’re supplying to, and whether the limitation is permitted and reasonable
- either way, you can use contracts to clarify scope, manage process, and (in some cases) limit liability in ways that are legally valid
Limitation Of Liability Clauses (The Right Way)
In the right context (often B2B supply), a limitation of liability clause can help cap your exposure and allocate risk sensibly.
However, these clauses need to be drafted carefully. If they’re too broad, unclear, or inconsistent with the ACL (including where consumer guarantees can’t be excluded), they may be unenforceable - and they can also create customer trust issues if they look unfair.
If you’re using these clauses (or thinking about it), it’s worth understanding the moving parts in limitation of liability clauses, including why wording and context matter.
Disclaimers: Helpful For Clarity, Not A Magic Shield
Disclaimers can be useful to explain assumptions, limitations and intended use. But a disclaimer won’t automatically override consumer guarantees.
Where disclaimers help most is in preventing confusion - for example, making it clear that a customer must confirm compatibility, or that outcomes depend on variables outside your control.
Depending on your business model, a tailored Disclaimer can form part of a wider compliance and risk strategy (particularly where you publish guidance, recommendations, or general information alongside your products/services).
Get Your Agreements Reviewed Before A Dispute Happens
The best time to fix gaps in your customer terms, warranty processes and liability clauses is before a customer complaint lands in your inbox.
If you’ve been using template terms (or something copied and pasted years ago), a Contract Review can help you confirm whether your terms match your real-world processes and risk profile - especially if you’ve expanded into online sales, subscriptions, or higher-value orders.
Key Takeaways
- Not fit for purpose is a core ACL concept and often turns on what a reasonable customer would expect, plus any specific purpose the customer made known to you.
- If goods or services are not fit for purpose, customers may be entitled to remedies - and the options can differ depending on whether it’s a major failure or non-major failure.
- Your own “warranty policy” doesn’t replace consumer guarantees, so you should be careful about blanket statements like “no refunds” or “warranty expired”.
- Clear product descriptions, written scopes, staff training, and consistent documentation are some of the best ways to prevent not fit for purpose disputes.
- Strong terms and conditions can’t contract out of the ACL, but they can still protect you by clarifying scope, setting processes, and managing risk in legally appropriate ways (and in some B2B cases, may also help you take advantage of permitted limitations).
- Having your contracts and warranty wording reviewed early can save you time, money and stress when a complaint comes in.
