Purchase Order Terms in New Zealand: Should You Accept?

A customer sends through a purchase order and the sale looks ready to go. Then you notice extra terms on the back page or in a linked PDF: 90 day payment, uncapped indemnities, a right to cancel at any time, and a clause saying their terms override yours.

Small suppliers often make three costly mistakes at this point. They ship the goods without reading the purchase order, assume their own terms of trade still apply, or accept the order by email without dealing with the conflicting terms. The result can be a customer purchase order contract that changes pricing, delivery, warranty, liability and payment risk.

You can usually manage this risk with a clear acceptance process, careful wording on quotes and invoices, and a practical approach to supplier terms vs purchase order terms. The key is to decide whether to accept, reject or counter-offer before performance begins.

Purchase Order Terms Checklist for New Zealand Suppliers

A purchase order should be treated as a contract document, not just an admin form, whenever it contains commercial or legal terms.

For a small New Zealand supplier, the practical question is not just whether the customer wants to buy. It is whether the customer is asking you to supply on terms that are worse than the deal you thought you had agreed. This comes up for manufacturers, wholesalers, consultants, SaaS providers, agencies, trades businesses and any supplier dealing with larger corporate or government-adjacent customers.

Before you accept a customer purchase order, check these points:

• Who is the contracting party: Confirm the customer's legal name, NZBN if available, and whether you are dealing with the company, a branch, a trust, or an individual trading under a business name.
• What documents are incorporated: Look for wording that imports standard terms, procurement policies, online terms, supplier codes, privacy schedules, security schedules, website terms of use or service levels.
• Payment timing: Check whether your 7 or 14 day payment term has become 30, 60 or 90 days after invoice approval, month-end, delivery acceptance or some other trigger.
• Price and scope: Confirm whether the purchase order matches your quote, especially for freight, installation, variations, licence scope, support, minimum quantities and GST.
• Delivery and acceptance: Look for delivery dates that are strict deadlines, acceptance testing rights, rejection rights, liquidated damages or penalties for delay.
• Liability cap: Check whether your cap has been removed, increased, or replaced with unlimited liability for certain losses.
• Indemnities: Watch for broad obligations to compensate the customer for losses that are only loosely connected to your fault.
• Warranties and guarantees: Identify warranties that go beyond your product specifications, service description or legal obligations.
• Intellectual property: Make sure you are not accidentally assigning ownership of your templates, software, designs, know-how or pre-existing materials.
• Confidentiality, privacy and data: Check whether you are required to meet specific Privacy Act 2020, security, audit or breach notification obligations.
• Termination rights: See whether the customer can cancel for convenience after you have ordered stock, allocated staff or started custom work.
• Priority clause: Look for wording that says the purchase order terms prevail over your quote, proposal, invoice or terms of trade.

The risk is higher where you receive a purchase order after negotiations are mostly done. For example, you may have sent a quote stating that your terms of trade apply, then the customer sends a purchase order saying its procurement terms apply instead. If you simply reply, confirmed, or start work, the customer may later argue that you accepted its terms.

Good contract control does not have to slow down every sale. You can create an internal rule that low-risk purchase orders go through sales operations, while purchase orders with high-value, unusual or conflicting terms need director approval. A simple escalation point can prevent a routine order from becoming an unexpected legal exposure.

When a Customer Purchase Order Becomes the Contract

A customer purchase order can become legally binding when the usual contract elements are present and your conduct shows acceptance.

In New Zealand, a contract generally forms when there is an offer, acceptance, consideration, intention to create legal relations and enough certainty about the deal. A purchase order can be the customer's offer to buy on stated terms. It can also be the customer's acceptance of your quote, depending on the sequence of documents and what each document says.

For suppliers, the tricky part is that acceptance does not always require a signed document. You might accept a purchase order by:

• signing and returning it;
• replying by email that the order is accepted;
• issuing an order confirmation that does not object to the customer's terms;
• shipping goods or starting services after receiving the purchase order;
• raising an invoice that refers to the customer's purchase order number; or
• continuing with a regular course of dealing where purchase orders are routinely treated as the basis for supply.

Context matters. If your quote clearly says it is subject to your terms of trade, and your customer sends a purchase order with different terms, your response becomes critical. An email saying, We accept your PO subject to our terms of trade attached and no other terms are accepted, is very different from an email saying, Thanks, all good.

Here is a common example. A Dunedin food packaging supplier sends a quote for 10,000 custom boxes at a fixed unit price, plus freight, with payment due 14 days after invoice. The quote states that the supplier's terms of trade apply. The customer then issues a purchase order that states payment is due 60 days after end of month, delivery is time critical, and the customer's standard purchase terms apply. If the supplier manufactures and ships the boxes without objecting, the customer may argue the purchase order terms form part of the contract.

The same issue appears in services. A marketing agency might agree a campaign scope over email, then receive a purchase order from the client's finance team. The purchase order may include ownership wording that says all intellectual property created or used in the services is assigned to the customer. If the agency starts work without reserving its background IP and templates, it may face a later dispute about what it can reuse for other clients.

Authority is another practical issue. Check whether the person issuing or approving the purchase order has authority to bind the customer. Larger organisations often have internal procurement rules, delegated authority limits and vendor onboarding processes. Those internal rules do not automatically protect you if the person appeared to have authority, but they can create payment delays if you skip the customer's required process.

Suppliers should also separate purchase orders from invoices. An invoice is usually issued after the supply has been agreed or completed. A purchase order often comes before supply and can set the contract terms. If your invoice repeats your terms after you have already accepted the customer's purchase order, it may be too late to make your terms prevail.

Supplier Terms vs Purchase Order Terms: Who Wins?

The terms that win are usually the terms the parties objectively agreed to, which can depend on the order of documents, wording, conduct and previous dealings.

The phrase battle of forms describes the situation where each party tries to contract on its own standard terms. In a battle of forms in NZ, there is no simple rule that the supplier always wins or the customer always wins. A court would look at what was offered, what was accepted, and whether later conduct showed agreement to a particular set of terms.

One common approach is sometimes called the last shot idea. If one party sends its terms last, and the other party performs without objecting, the last set of terms may have a stronger argument. That is why a customer's purchase order can be risky if it arrives after your quote and you then supply without pushing back.

However, the answer is not always mechanical. A long-standing course of dealings may support your terms if every previous sale was on your terms and the customer knew that. Clear wording on your quote, order confirmation and account opening forms can also help. On the other hand, if your team routinely accepts customer purchase orders and never sends your terms until the invoice stage, it becomes harder to argue that your terms were incorporated early enough.

Priority clauses can reduce uncertainty. A supplier's quote or order confirmation might say:

Our terms of trade apply to the supply. Any terms in a customer purchase order or other customer document are rejected and do not apply unless we expressly agree to them in writing.

A customer purchase order might say the opposite:

The supplier accepts the buyer's purchase terms. Any supplier terms are excluded, even if referred to in a quote, delivery docket or invoice.

If both documents contain priority wording, the practical winner may depend on what happens next. Did you object? Did the customer accept your counter-offer? Did both sides proceed while knowing there was a mismatch? The commercial value of the order, relationship leverage and the clarity of each document all matter.

Terms of trade and purchase orders should be designed to work together rather than collide by accident. Your sales process should make your terms visible before the customer orders. For example, your quote can include your key commercial terms and clearly state that your full terms of trade apply. Your order confirmation can repeat that you are accepting the purchase order only on your terms. Your delivery docket can avoid saying anything that appears to accept the customer's terms.

Some suppliers use a tiered approach. For ordinary customers, they require acceptance of their own terms before opening an account or processing the first order. For major customers, they review the customer's procurement terms and agree specific amendments. This is often more realistic than insisting every customer use your exact document, especially when dealing with national retailers, councils, health sector customers or large enterprise clients.

Be careful with silence. If a customer sends you a purchase order containing new terms and you stay silent but perform, your conduct can speak louder than your documents. A short written objection before supply is much safer than trying to explain months later that you never meant to accept the extra terms.

Risk Terms to Negotiate Before You Accept

The terms worth negotiating are the ones that change your cash flow, expand your liability or give the customer control over your work without matching compensation.

Not every mismatch needs a lawyer or a long negotiation. A minor formatting issue or purchase order number requirement might be harmless. The bigger concern is a term that transfers commercial risk to you in a way your pricing, insurance or delivery model does not support.

Payment Terms and Set-Off Rights

Payment terms can quietly change the economics of a deal. A purchase order might say payment is due 60 days after the later of invoice, delivery, acceptance, receipt of all documentation, or end of month. For a small supplier buying materials upfront, that can create a cash flow gap.

Watch for set-off clauses. These allow the customer to withhold payment for amounts it claims you owe, sometimes across unrelated contracts or group companies. A narrow set-off right for genuine, undisputed amounts may be manageable. A broad right to withhold all payments because of an alleged issue can create pressure even when the customer's complaint is weak.

Practical changes to request include:

• a fixed due date after a valid tax invoice;
• clear acceptance procedures with deemed acceptance if the customer does not respond within a stated period;
• a right to charge interest or suspend supply for overdue amounts;
• no set-off except for undisputed amounts under the same order; and
• deposits, milestone payments or prepayment for custom goods and high-cost materials.

Liability Caps, Indemnities and Exclusions

Liability wording can turn a modest order into a major financial risk. A customer purchase order may include unlimited liability for breach, broad indemnities, liability for indirect loss, or obligations to cover the customer's lost profits, recall costs and third-party claims.

A supplier-friendly position usually includes a liability cap, such as fees paid or payable under the order, and an exclusion of indirect or consequential loss. Some losses may sit outside the cap, such as fraud, wilful misconduct, confidentiality breaches, privacy breaches or intellectual property infringement. The right carve-outs depend on the deal and your insurance.

Indemnities need close reading. An indemnity for loss caused by your negligence or breach is very different from an indemnity for any loss connected with the goods or services, regardless of fault. Push for fault-based wording, reasonable mitigation obligations, and control over claims where you are paying the bill.

Warranties, Consumer Law and Fair Trading Risk

Warranties should match what you can genuinely promise. Avoid accepting broad guarantees that goods are fit for every purpose the customer may have, unless you know and have priced for that purpose.

The Consumer Guarantees Act 1993 is mainly focused on consumer supplies, but it can still affect business supply chains. If goods or services are acquired for business purposes, parties can often contract out of the Consumer Guarantees Act where it is fair and reasonable to do so. If your customer is buying for resale to consumers, your quality promises, product descriptions and after-sales processes may still have downstream consequences.

The Fair Trading Act 1986 also matters. You should avoid statements that mislead customers about price, performance, origin, endorsements, availability or warranties. Standard form small trade contracts can also be affected by unfair contract terms rules. If you use your own standard terms against smaller business customers, those terms should not be one-sided in a way that creates avoidable regulatory risk.

Delivery, Acceptance and Cancellation

Delivery clauses should reflect real operational constraints. A strict delivery date may be risky if you depend on imported components, third-party freight, customer approvals or site access.

Look for purchase order terms that allow the customer to reject goods for minor defects, delay acceptance testing, cancel for convenience, or change quantities at short notice. These terms are particularly risky for custom products, perishable goods, event supplies, installation work and services that require dedicated staff.

A more balanced position may include a clear variation process, practical cure rights, restocking fees, payment for work in progress, and customer obligations to provide access, information and approvals on time.

IP, Confidentiality, Privacy and Data

IP clauses can have long-term consequences beyond the order value. If you create designs, software, training materials, reports, product specifications or creative work, check whether the customer is seeking ownership or just a licence to use the deliverables.

Keep a clear distinction between your pre-existing materials and newly created deliverables. You may agree that the customer owns final, paid-for deliverables while you retain ownership of tools, templates, know-how, software libraries and methods developed before or outside the project.

Privacy and data terms also deserve attention where you handle personal information. The Privacy Act 2020 requires agencies to handle personal information in line with the Information Privacy Principles, and notifiable privacy breaches may need to be reported to the Privacy Commissioner and affected individuals. A customer's purchase order may impose shorter notification timeframes, audit rights, data location rules or security standards. Make sure your systems and subcontractors can meet those obligations before accepting them.

How to Make Your Terms Prevail

Your terms are more likely to prevail when they are provided early, accepted clearly and reinforced consistently.

Start with your quote or proposal. It should identify the goods or services, price, GST treatment, delivery assumptions, expiry date, and a statement that your terms of trade apply. Provide your full business terms and conditions at the same time, not only after the order is placed.

Then control your acceptance wording. If the customer's purchase order includes extra terms, do not simply accept it. Use a counter-offer that makes your position clear. For example:

We confirm receipt of your purchase order. We can proceed with the supply on the basis of our quote dated [date] and our terms of trade. We do not accept any additional or inconsistent terms in your purchase order unless expressly agreed in writing by us.

If the customer needs its purchase order number on invoices for admin reasons, say that you are using the number for billing reference only and not accepting the customer's legal terms. Keep the wording polite and commercial. Many procurement teams are used to this issue and may accept a sensible amendment, especially where the commercial terms are already agreed.

For high-value orders, create a marked-up purchase order amendment or a short special conditions document. This can state which customer terms are accepted, which are amended, and which supplier terms remain in force. A short negotiated document is often easier than arguing over two full sets of standard terms.

Train your team on red flags. Sales staff should know when a purchase order needs review before they reply. Operations staff should avoid starting work on conflicting terms just because a customer is pushing for delivery. Accounts staff should avoid sending invoices that accidentally refer to customer terms as accepted.

Finally, keep records. Save the quote, terms of trade, purchase order, emails, order confirmations, delivery records and any agreed amendments in one place. If a payment or liability dispute later arises, a clean document trail can make the difference between a quick commercial resolution and a drawn-out argument.

FAQs

Can I Accept a Purchase Order but Reject the Customer's Terms?

Yes, but your rejection must be clear and made before you perform. Reply that you can supply only on your quote and terms of trade, and that any additional or inconsistent customer terms are not accepted unless agreed in writing.

Does a Purchase Order Override My Terms of Trade?

It can, especially if the purchase order is sent after your quote and you accept or perform without objection. Your chances are stronger if your terms were provided early, your quote says they apply, and your acceptance expressly rejects conflicting purchase order terms.

What Is a Battle of Forms in NZ?

A battle of forms is where the supplier and customer each put forward their own standard terms. In New Zealand, the outcome depends on the documents, timing, wording, conduct and prior dealings rather than a simple automatic rule.

Should I Refuse All Customer Purchase Order Terms?

No. Some purchase order terms are harmless or commercially necessary, such as billing references and delivery instructions. Focus on terms that affect payment, liability, cancellation, IP, privacy, warranties and operational obligations.

Can I Rely on Terms Printed on My Invoice?

Invoice terms are often too late if the contract was already formed when you accepted the purchase order or supplied the goods. Put your terms in your quote, account opening process and order confirmation before the customer commits.

Key Takeaways

• A customer's purchase order can create or change the contract if you accept it by email, signature, conduct or delivery.
• Conflicting terms should be handled before performance starts, particularly where payment, liability, indemnities, warranties, IP or cancellation rights are affected.
• In a battle of forms, New Zealand suppliers should not assume their own terms win automatically. Timing, wording and conduct matter.
• Your terms of trade are more effective when they are provided with the quote, clearly incorporated, and repeated in your order confirmation.
• High-value or unusual purchase orders should be reviewed and, where needed, accepted only with written amendments or special conditions.
