Pricing mistakes happen to even the most careful businesses.
It could be a shelf label that wasn’t updated after a sale ended, a POS (point of sale) system glitch, a staff member who keyed in the wrong amount, or an online store displaying the wrong price due to an integration issue.
And when it happens, customers often arrive with a very specific expectation: that you’ll honour the lower price.
It’s also common for people to jump online and look up things like Kmart’s wrong price policy when they experience a pricing error in-store. As a small business owner, you don’t want to copy another business’s policy (and you definitely don’t want to accidentally say something that creates a legal obligation you didn’t intend). But you do want to understand what Australian law requires, what you can choose to do as a customer-service decision, and how to write a “wrong price” policy that protects your business.
Below, we break down the legal and practical considerations for pricing errors in Australia, and how to build a clear policy and process your team can follow with confidence.
What Counts As A Pricing Error (And Why It’s So Common)?
A “pricing error” usually means there’s a mismatch between:
- the price displayed to the customer (on a shelf, tag, sign, menu, website listing or advertisement); and
- the price your business attempts to charge at checkout (in-store or online).
Common examples we see in small businesses include:
- Shelf vs checkout mismatch: The shelf ticket says $19.99, but the register scans $29.99.
- Old promotional signage: A “50% off” sign wasn’t removed after the campaign ended.
- Incorrect unit pricing: The per-100g price is right, but the “each” price is wrong (or vice versa).
- Online store errors: A product page shows the wrong price because of a bulk upload, rounding issue, discount code stack, or integration with a third-party platform.
- Mislabelled product: The label on the item is for a different product/variant (e.g. wrong size or model).
Because small businesses often rely on lean teams and fast-moving stock, it’s easy for these mismatches to occur. The key is what you do next: your response should be consistent, fair, and legally safe.
Do You Have To Honour The Wrong Price In Australia?
This is the big question business owners ask: if you advertised or displayed the wrong price, do you have to sell at that price?
In many everyday retail situations, displaying a price is not automatically a binding promise to sell at that price. Often, it’s treated as an “invitation to treat” (essentially, an invitation for the customer to make an offer to buy).
In practical terms, that often means:
- If you discover the mistake before the sale is completed, you can generally stop the sale (or refuse to sell at the incorrect price) and offer the customer the choice to buy at the correct price instead; and
- You should ensure you don’t charge more than the price that was displayed - if the displayed price is wrong, the safer approach is to correct the price (or remove/correct the sign or listing) and give the customer the option to proceed or walk away.
However, you need to be careful here. While the law may not force you to honour every accidental price, Australian Consumer Law (ACL) still applies to how you advertise and display prices, and to how you behave once you become aware of an error.
From a risk perspective, the more “systematic” or “misleading” the pricing issue looks (even if unintentional), the more likely it becomes a compliance problem rather than a one-off customer service issue.
For business owners, it helps to separate two concepts:
- Contract / sale formation: whether a sale is legally locked in at the wrong price; and
- Consumer law compliance: whether your pricing display or advertising could be misleading, even if you correct it later.
If you want a deeper overview of how consumer rules work in practice for businesses, it’s worth understanding the basics of Australian Consumer Law and how it applies to advertising, checkout flows, and customer communications.
What If The Customer Has Already Paid?
If the customer has already paid and the sale is complete, trying to unwind the transaction can be messy.
Depending on the situation, cancelling the sale unilaterally may create legal and reputational risk. If you do need to cancel because of a genuine pricing error, you’ll generally need to act quickly, communicate clearly, and provide an appropriate refund (and any other ACL-required remedy) so you don’t end up in a dispute about unfair treatment or misleading conduct.
In online transactions, your website terms and checkout design also matter (for example, whether you reserve the right to cancel orders due to pricing errors, when you treat an order as “accepted”, and how refunds are handled if an order is cancelled).
This is where a well-drafted set of Website Terms & Conditions can make a real difference, especially if you sell products online or take payment before final confirmation.
Consumer Law Risks: When A “Wrong Price” Becomes Misleading Advertising
Even if a genuine pricing mistake occurs, your business still needs to manage the consumer law risk. The ACL prohibits misleading or deceptive conduct, and also has specific pricing and advertising expectations.
Some pricing errors are “honest mistakes” that you can correct quickly with minimal risk. Others can look like a strategy (even if it isn’t), such as advertising a very low price to get customers in the door and then charging more at checkout.
Key risk areas include:
- Misleading shelf or online display pricing: If the displayed price is wrong and not corrected promptly (or if customers are charged more than the displayed price).
- Promotional claims that don’t match reality: e.g. “Today only” sales, or “was/now” pricing that isn’t accurate.
- Systemic errors: If multiple customers are affected, or the issue continues over days/weeks.
- Staff statements: If team members make promises like “we always honour ticketed price” and then you don’t.
A useful way to think about it is: what impression is your pricing giving to an ordinary customer? If it’s likely to lead customers to believe a certain price applies, the ACL may be triggered even if you didn’t intend to mislead.
If you want to pressure-test your advertising and checkout messaging, the concepts in misleading or deceptive conduct are a good place to start.
Displayed Price Compliance (Including In-Store Signage And Online Listings)
Australia has specific expectations around how prices are displayed, including ensuring prices are clear and not confusing.
For example, you should be careful about:
- showing partial prices without unavoidable fees;
- showing a sale price but still charging the original price at checkout;
- unit pricing errors (especially in grocery/food retail); and
- online pricing where GST or delivery is treated inconsistently.
Many small businesses build their internal processes around these obligations, and it’s also worth being familiar with the general principles behind advertised price laws.
How To Create A “Wrong Price Policy” For Your Small Business
A “wrong price policy” is not a legal requirement. It’s a business policy you choose to adopt to manage customer expectations, reduce disputes, and keep your team consistent.
The goal is to avoid two extremes:
- Too rigid: Staff feel forced to argue with customers over small amounts, leading to complaints and reputational damage.
- Too generous (without boundaries): You accidentally create an expectation that your business will always honour any price error, even if it’s a clear typo or exploitation.
When you’re drafting your policy, it helps to decide upfront:
- When you’ll honour the displayed price;
- When you’ll correct the price instead (and offer the customer the option to proceed or walk away);
- Who in your team can approve exceptions; and
- How you’ll document incidents to prevent repeat issues.
Practical Options For Your Policy (Choose What Fits Your Business)
Here are common policy approaches we see in Australian small businesses:
- Honour the lower price (within limits): For example, honour the displayed price if the difference is under $X or if the customer raises it politely at checkout.
- Honour only if not “obviously” incorrect: For example, you don’t honour $50 items priced at $5 due to a clear typo.
- Honour once, then correct signage immediately: This can be a good balance between goodwill and preventing repeat loss.
- Offer a small goodwill discount instead: Particularly where the error is noticed after payment or where stock is limited.
- Cancel and refund (online orders): If you catch an error before dispatch, you cancel and refund promptly with a clear explanation (supported by your terms).
There isn’t one “right” answer. The best policy is one that reflects your margins, product types, staff capability, and customer base.
Be Careful Not To Accidentally Promise A Competitor-Style Policy
Many customers search for things like “Kmart wrong price policy” (or similar phrases) because they think all retailers must follow a particular industry standard.
As a small business, you should avoid writing your policy in a way that suggests you’re bound to honour any incorrect price in every situation. If you publish a policy, treat it like a public commitment: keep it accurate, realistic, and aligned with what your staff can actually deliver day-to-day.
What Should You Train Staff To Do When A Pricing Error Happens?
A policy is only as good as the process behind it.
When a pricing error is raised, you want your team to respond in a way that is:
- Calm and consistent (so customers don’t feel like the outcome depends on who is on shift);
- Fast (so queues and frustration don’t build);
- Documented (so you can fix the underlying cause); and
- Legally sensible (so you don’t say things that create an obligation or look misleading).
A Simple In-Store Script Your Team Can Use
It often helps to give staff a short “approved script” for checkout disputes. For example:
- “Thanks for pointing that out - let me check the shelf label/sign.”
- “It looks like the shelf label hasn’t been updated. The correct price is $__. Would you still like to proceed?”
- “As a goodwill gesture, we can honour the displayed price this time / apply a discount of $__.”
- “We’ll fix the label right away so it doesn’t affect anyone else.”
This approach reduces arguments and helps your staff avoid making statements that sound like “we always have to honour it”, which can escalate the situation if you later decide you can’t.
Online Stores: Your Checkout Flow And Terms Matter
Online pricing errors can spread quickly. If a wrong price is shared on social media, you might suddenly receive dozens (or hundreds) of orders in minutes.
To reduce risk, consider:
- Clear order acceptance wording: e.g. order confirmation is a receipt of the order, not acceptance until dispatch.
- A pricing error clause: reserving the right to cancel/refund orders affected by genuine and obvious errors (and explaining how refunds will be processed).
- Fast internal escalation: so your team can pause ads, correct the listing, and stop further orders.
- Consistent refund messaging: short, factual, and apologetic without admitting to intentional wrongdoing.
Also remember that if you advertise something online, customers may assume the listed price applies to them. Keeping your pricing displays compliant (and correcting errors quickly) is a key part of reducing disputes and complaints.
What Legal Documents Help Manage Pricing Disputes?
Small businesses often think of pricing disputes as “just customer service”. But if you sell online, take deposits, run promotions, or advertise regularly, your legal documents and public-facing terms can significantly reduce confusion.
Here are documents worth considering:
- Website Terms & Conditions: These can explain when an order is accepted, how pricing is displayed, and your process if an error occurs (especially useful for ecommerce). Your Website Terms & Conditions should match how your store actually operates.
- Refunds/Returns Policy: A clear policy helps staff respond consistently, and helps customers understand the difference between change-of-mind returns and ACL remedies.
- Promotion terms: If you run sales, giveaways or limited-time offers, having written terms reduces “but the sign said…” disputes and helps you apply exclusions fairly.
- Quotation / booking terms (for service businesses): If you quote customers (especially for custom work), you should be clear about how long a quote lasts and what happens if pricing inputs change. Many business owners ask is a quotation legally binding because the answer depends on how the quote is presented and accepted.
Be Careful With Cancellation Fees And “No Refund” Language
If a pricing error affects a booking or order and you need to cancel, you should be cautious about how cancellation fees are handled. Charging (or refusing to refund) a fee when the error was on your side can quickly become a complaint issue.
If you use cancellation fees, it’s important to ensure they’re clearly disclosed and legally enforceable in your context. The rules can be nuanced, so it’s worth understanding how cancellation fees interact with consumer law obligations.
Key Takeaways
- Pricing errors are common in both physical stores and online businesses, but your response should be consistent and documented so the issue doesn’t repeat.
- In many cases, you can correct the price (or stop the sale) before the transaction is completed - and you should avoid charging more than the displayed price while the incorrect display remains in place - but consumer law still applies to how prices are displayed and advertised.
- A “wrong price policy” is a business decision (not automatically a legal requirement), and it should balance customer goodwill with clear limits that protect your margins.
- Customer searches like “Kmart wrong price policy” reflect a common expectation that retailers “must” honour wrong prices - your business should set its own policy carefully and avoid accidental promises.
- Misleading price displays and repeated errors can create Australian Consumer Law risk, especially if customers are likely to be led into believing a certain price applies.
- Your legal documents (especially ecommerce terms, returns policies, and quote/booking terms) can reduce disputes and support your team when an error occurs.
