When To Use eCommerce Terms And Conditions (2026 Updated)

When you’re building an online store, it’s easy to focus on the fun parts first: your products, branding, website design, and getting your first sales through the door.

But if you want to be properly protected from day one, you also need to get your legal foundations right - and for most online businesses, that starts with solid eCommerce Terms and Conditions.

This guide is updated for current expectations around online selling in New Zealand, including how customers buy (and complain) online, how payments and delivery actually work in practice, and how regulators look at online advertising and consumer rights.

We’ll walk you through when you should use eCommerce Terms and Conditions, what they should cover, and the common situations where relying on “generic website terms” (or nothing at all) can get messy fast.

What Are eCommerce Terms And Conditions (And What Do They Actually Do)?

eCommerce Terms and Conditions (sometimes called “online store terms” or “terms of sale”) are the rules that apply when a customer buys something from your website.

They’re the document that sets out things like:

• how orders are placed and accepted
• pricing and payment rules
• shipping and delivery terms
• returns, refunds, and exchanges
• who owns what (including intellectual property on your site)
• limits on liability (where legally allowed)
• how disputes will be handled

In plain terms, your eCommerce Terms and Conditions help you set expectations with customers before anything goes wrong.

They also help you show that you’ve been transparent about key conditions of sale - which is especially important in New Zealand where consumer protection laws are strict, and the wording of your online promises (including on product pages and ads) can matter.

If you already have a general set of Website Terms and Conditions, that’s a good start - but for many online stores, you’ll need something more specific that deals with the buying process (not just browsing your site).

When Should You Use eCommerce Terms And Conditions?

If you take payments online for goods or services, you should strongly consider eCommerce Terms and Conditions. It’s one of those documents that feels “optional” until you get your first complaint, chargeback, or delivery dispute.

Here are the most common situations where eCommerce Terms and Conditions are the right tool.

If Customers Can Buy Directly From Your Website

If your website has a cart and checkout (Shopify, WooCommerce, Squarespace Commerce, custom build - all of it counts), you’re running an eCommerce store.

Even if you’re small, even if it’s “just a side hustle”, even if you’re only selling a few products a week - you’re still entering into contracts with customers every time they purchase.

eCommerce Terms and Conditions let you clearly document what that contract includes.

If You Sell Physical Products That Need Shipping Or Delivery

Delivery is one of the biggest friction points in online selling, because it involves third parties and things you can’t fully control.

Your terms can cover practical issues like:

• when an order is considered shipped
• estimated delivery times (and that they’re estimates)
• what happens if a parcel is delayed, lost, or damaged in transit
• address accuracy and re-delivery costs
• risk and title (i.e. when ownership/risk passes)

Without this, you may be stuck arguing with customers about what was “promised” - and in many cases, customers will default to whatever they believe is fair (or whatever your marketing implied), not what works operationally for your business.

If You Offer Returns, Refunds, Or Exchanges (Or Want To Control The Process)

Returns are normal in eCommerce. The legal risk comes when your returns process is unclear, inconsistent, or contradicts consumer law.

A good set of eCommerce Terms and Conditions should work alongside your day-to-day store policy, and align with New Zealand consumer protections under the Consumer Guarantees Act 1993 and Fair Trading Act 1986.

It also helps to set clear “process rules”, for example:

• how customers request a return
• timeframes for returning items
• what condition items must be in (as long as it’s lawful and reasonable)
• how refunds are paid (e.g. original payment method)
• who pays return shipping in different scenarios

Many businesses also set out a separate refunds policy for easy reading. The key is making sure your policies don’t overpromise, don’t mislead, and don’t try to contract out of non-excludable rights. If you want to pressure-test your approach, it’s worth checking how your returns, refunds, and exchanges position lines up with NZ consumer law.

If You Sell Digital Products, Online Courses, Or Downloads

Digital products can be great for margins - but they come with unique issues around access, delivery, and chargebacks.

Your terms should address things like:

• when access is granted
• licensing (what the customer can and can’t do with the content)
• no sharing or redistribution rules
• restrictions on refunds after download/access (to the extent permitted by law)

If you’re running a subscription or hosted platform, you may also need terms that look more like a platform agreement than a basic online store policy. In many cases, that’s where a tailored Subscription Terms and Conditions (or similar) makes more sense than standard retail terms.

If You Take Pre-Orders, Backorders, Or “Limited Drops”

If you sell products that aren’t ready to ship yet, pre-orders can create a mismatch between what the customer expects and what you can deliver.

Your terms should explain:

• that the order is a pre-order
• expected dispatch windows (and the risk of delays)
• how customers can cancel (if allowed)
• what happens if you can’t supply the item

This is also where the way you describe the product matters. Overly confident “guaranteed shipping by X date” statements can become a problem if they’re not accurate.

If You Sell Through Social Media But Direct Customers To Pay Online

Even if your main marketing is on Instagram, TikTok, or Facebook Marketplace, if the transaction happens via a payment link, checkout page, or invoice tied to your online process, your eCommerce Terms and Conditions can still apply.

The main point is this: if you’re selling remotely and taking payment without face-to-face negotiation, you should have clear sale terms somewhere customers can access before purchase.

What Should Your eCommerce Terms And Conditions Cover?

There’s no one-size-fits-all set of eCommerce Terms and Conditions in New Zealand. What you need depends on what you sell, how you fulfil orders, and what risks you’re most likely to face.

That said, there are some core clauses that most online stores should consider including.

Order Process And Contract Formation

This section answers a surprisingly important question: when is the contract actually formed?

Many online stores set it up so the contract forms when you accept the order (not when the customer clicks “buy”), giving you room to cancel orders for genuine reasons (like stock errors or obvious pricing mistakes).

This also ties into whether a website listing is an offer or an invitation to treat - and why your terms should clearly state how acceptance works.

Pricing, Payment, And Errors

You’ll want terms that address:

• prices being in NZD (if that’s correct for your store)
• GST (whether prices include it)
• payment methods and processing
• what happens if there’s a pricing error
• fraud prevention and verification checks

This is particularly useful if you’ve ever worried about a customer screenshotting a mispriced product and insisting you must honour it. The legal answer can depend on the facts, but clear terms can reduce the argument significantly.

Shipping, Delivery, And Risk

Delivery issues are one of the most common sources of disputes for eCommerce businesses.

Your terms should match how your fulfilment really works. For example:

• If you use third-party couriers, say so.
• If delivery timeframes are estimates, make that clear.
• If you don’t ship to certain regions, list them (or link to a shipping page).

Just keep in mind: while terms can allocate risk between you and the customer to a degree, you can’t use terms to mislead customers or strip away rights that apply under New Zealand consumer law.

Returns, Refunds, Exchanges, And Consumer Guarantees

Your terms should clearly separate:

• your voluntary policy (for example, “change of mind” returns), and
• consumer rights that apply regardless of your policy (for example, remedies for faulty products).

This is where a lot of businesses accidentally get it wrong - they copy terms from overseas websites that say “no refunds under any circumstances” or “returns only within 7 days” without acknowledging NZ consumer protections.

A better approach is to draft terms that explain your process while still recognising that the Consumer Guarantees Act 1993 can apply when you sell to consumers in trade.

Product Descriptions, Images, And “What You See” Online

In eCommerce, the product page often does the job of an in-store salesperson.

So your terms should support accurate product descriptions and manage common limitations, like:

• colour variation due to screens/lighting
• product updates (where your suppliers change materials or packaging)
• handmade or natural variation (where applicable)

This can reduce disputes where customers argue the product “wasn’t as described”. You still need to comply with the Fair Trading Act 1986 (including not making misleading representations), but well-drafted terms can help you explain these realities clearly and consistently.

Limits Of Liability (Where Allowed)

Limitation of liability clauses can be useful, but they’re not a magic shield.

In New Zealand, you generally can’t contract out of certain consumer guarantees for consumer customers. For business-to-business sales, there may be more flexibility, but you need the drafting to be right and tailored to your circumstances.

If you sell to both consumers and businesses, you may need different wording (or different flows at checkout) to reflect that.

Privacy And Customer Data

Most online stores collect personal information, such as names, addresses, phone numbers, and email addresses. If you collect and use personal information, you’ll usually need a Privacy Policy to explain what you collect, how you use it, and how you store it.

Your eCommerce Terms and Conditions often link out to your Privacy Policy, but they shouldn’t try to “hide” privacy obligations inside dense legal wording. Under the Privacy Act 2020, transparency is a big part of doing things properly.

Common Scenarios Where You’ll Be Glad You Had eCommerce Terms

Terms and Conditions can feel theoretical until something happens. Here are real-world scenarios (the kind we see all the time) where good eCommerce Terms and Conditions make a difference.

A Customer Claims They Didn’t Authorise The Purchase

If you deal with chargebacks, you’ll know they’re time-consuming and stressful.

Your terms can help you show what information you collect at checkout, what verification steps you take, and your process for investigating suspicious orders. It won’t eliminate chargebacks, but it can help you respond consistently and fairly.

You Run Out Of Stock After Someone Orders

Stock syncing errors happen, especially if you sell across multiple channels.

Your terms should allow you to cancel and refund an order where supply isn’t available, rather than being forced into a dispute about whether you “must” supply.

A Parcel Is Marked Delivered But The Customer Says It Never Arrived

This is a classic one. Your terms can spell out how delivery is evidenced (for example, courier tracking), what customers must do if they think something has gone wrong, and how quickly they need to notify you.

You still need to handle complaints fairly and in line with applicable law, but you’ll be doing it within a clear framework rather than improvising.

A Customer Wants A Refund For “Change Of Mind”

Some online businesses offer change-of-mind returns as a customer-friendly policy. Others don’t (or only for certain products).

The key is consistency and clarity. If your policy is “no change-of-mind returns”, you need to state it clearly before purchase - and your terms should still acknowledge that faulty products are treated differently under consumer law.

You Sell Promotions, Discount Codes, Or Run Flash Sales

If you use discount codes, “buy one get one”, limited-time deals, or free gifts with purchase, you’ll want terms that cover:

• eligibility rules
• expiry dates
• one-use limitations
• what happens if the promotion is misused

This ties closely to advertising accuracy. If you’re unsure whether your marketing wording could create a legal promise, getting advice early is much cheaper than trying to fix a dispute later.

How Do eCommerce Terms And Conditions Interact With NZ Consumer Law?

This is where it’s worth being really clear: eCommerce Terms and Conditions don’t replace New Zealand consumer law.

Instead, they should be drafted to work with it.

The Fair Trading Act 1986

The Fair Trading Act 1986 is about truthful conduct in trade. For eCommerce, this often shows up around:

• pricing displays (including sale pricing and “was/now” claims)
• product descriptions and images
• delivery claims (“ships today”, “guaranteed delivery”, etc.)
• refund and warranty statements

Your terms can help clarify how your store works, but they can’t “undo” misleading statements elsewhere on your site. This is why your product pages, ads, and policies all need to align.

The Consumer Guarantees Act 1993

The Consumer Guarantees Act 1993 (CGA) gives consumers automatic guarantees when they buy goods and services from a business “in trade”. These include (among others) that goods are of acceptable quality, fit for purpose, and match their description.

If you sell to consumers, you generally can’t contract out of the CGA. So terms like “all sales final, no refunds ever” can land you in trouble if they imply customers have fewer rights than they actually do.

Where things get more nuanced is when you sell to business customers. In some business-to-business situations, contracting out of the CGA may be possible - but it needs to be done carefully and clearly.

Unfair Contract Terms Considerations

Even when you can include protective clauses, the terms need to be fair and transparent. If your terms are overly one-sided, hidden, or confusing, they may create enforceability issues and customer complaints (and sometimes regulatory attention).

A good rule of thumb: your terms should protect your business, but they should also reflect what you genuinely do in practice.

Key Takeaways

• eCommerce Terms and Conditions are the core legal rules for how customers buy from your online store, and they help you manage disputes around orders, delivery, returns, and payment.
• You should use eCommerce Terms and Conditions if customers can purchase online, especially if you ship physical goods, offer digital products, or run promotions and pre-orders.
• Your terms should clearly cover order acceptance, pricing and payment, shipping and delivery, returns and refunds, liability limits (where lawful), and key operational realities like stock availability.
• eCommerce Terms and Conditions need to align with New Zealand consumer laws, including the Fair Trading Act 1986 and Consumer Guarantees Act 1993, and shouldn’t try to remove non-excludable consumer rights.
• If you collect customer personal information (which most online stores do), you’ll usually also need a clear Privacy Policy that supports your compliance with the Privacy Act 2020.
• Avoid relying on generic templates - your terms should match how your store actually operates, because “legal fine print” won’t help if it doesn’t reflect reality.
