How to Set Clear Credit Terms in New Zealand

Offering credit can help you win customers, smooth out repeat orders and stay competitive, but vague payment terms can create cash flow stress very quickly. Many New Zealand businesses make the same mistakes: they rely on a quote instead of a signed credit agreement, they leave out what happens when an invoice is overdue, or they copy generic terms that do not fit how they actually trade. Those gaps tend to show up at the worst time, usually when a customer is late paying and starts disputing what was agreed.

Clear credit terms set the rules before goods or services are supplied. They spell out when payment is due, whether a credit limit applies, what security or guarantees are required, and what happens if the customer defaults. This guide explains how to set clear credit terms in New Zealand, what clauses matter most, where founders often get caught out, and what to check before you sign or accept a customer onto an account.

Overview

Clear credit terms reduce disputes because both sides know exactly when payment is due and what happens if the account falls behind. For New Zealand businesses, the best approach is to use written terms that match your actual trading process, then make sure those terms are accepted before you provide goods or services on credit.

  • Define the payment period clearly, such as 7, 14 or 30 days from invoice date, or another specific trigger.
  • State any credit limit, review rights and your ability to suspend supply if the account is overdue.
  • Set out default consequences, including interest, recovery costs, cancellation rights and when all amounts become immediately due.
  • Check whether you need extra protection, such as a director guarantee, personal property security clause, or retention of title wording for goods.
  • Make sure the customer actually accepts the terms before you sign, before you take orders, or before you continue supply on account.
  • Keep your invoicing, application form and ongoing account management consistent with the legal terms.

What This Means For Your Business

Setting clear credit terms means documenting the commercial rules of your customer account in a way that is enforceable, practical and easy to use day to day. It is not just about writing “payment due in 30 days” on an invoice.

If you are a wholesaler, contractor, service provider, manufacturer or B2B supplier, credit terms often sit across several documents. You may have a credit application, terms of trade, quote, purchase order process and invoice conditions. Problems start when those documents say different things, or when the customer never clearly agreed to the one you want to rely on.

At a practical level, your credit terms should answer five basic questions.

  • Who is the customer legally responsible for payment?
  • How much credit are you offering, and on what basis?
  • When must invoices be paid?
  • What rights do you have if payment is late or the customer becomes insolvent?
  • What security do you hold if the customer does not pay?

Use the right contracting party

The first issue is identity. If the account is opened in the wrong name, recovery can become much harder. Before you sign, check whether you are dealing with a company, a sole trader, a partnership or a trust.

For a company customer, use the full legal name and New Zealand Company Number. If a trading name appears on the paperwork, that should not replace the legal entity name. A business name alone may not tell you who actually owes the debt.

For trusts and partnerships, extra care is needed because liability can be more complicated. If the customer structure is unclear, that is where founders often get caught.

Set payment terms with precision

Your payment clause should be specific enough that there is no real argument about due dates. “Prompt payment required” is too loose. “Payment due by the 20th of the month following invoice date” is much clearer.

Use wording that fits how you trade. Common options include:

  • payment due on delivery
  • payment due 7, 14 or 30 days from invoice date
  • payment due on a fixed date each month
  • deposit upfront with balance due on completion
  • progress payments triggered by project milestones

If your business allows staged work or partial deliveries, say how those are invoiced. If a dispute only affects part of an invoice, your terms can also state whether the undisputed amount must still be paid on time.

Match your terms to your real sales process

Credit terms only work if they fit the way orders are actually placed. If your team takes orders by phone and sends invoices later, then relying on invoice fine print alone may be risky because the customer may not have accepted those terms before supply.

You are usually in a stronger position where the customer signs a credit application or accepts terms during onboarding. For online trade accounts, make sure acceptance is recorded clearly and the current terms are easy to identify. For long term supply relationships, review whether updated terms need to be reissued and accepted.

Think beyond payment dates

A good credit agreement does more than set a due date. It gives you practical rights if the account goes off track.

Important clauses often include:

  • the right to reduce or withdraw credit at any time
  • the right to suspend further supply if invoices are overdue
  • default interest on overdue amounts
  • liability for debt recovery costs, where legally appropriate and clearly drafted
  • an acceleration clause so all outstanding amounts become immediately due after default
  • your ability to allocate payments to older invoices or unsecured debts first
  • notice and service provisions, so formal communications can be sent effectively

These points matter because late payment disputes are rarely just about one overdue invoice. They often involve ongoing orders, partial payments, arguments over quality, or a customer asking for more time after the debt has already grown.

Consider security where the risk justifies it

If you supply goods on account, an unsecured promise to pay may not be enough. Higher risk accounts often justify extra protection.

Depending on the deal, this may include:

  • a director or personal guarantee from the people behind the customer company
  • retention of title wording that says ownership of goods remains with you until payment is made in full
  • a security interest that can be registered on the Personal Property Securities Register if the documents are drafted correctly
  • deposits or part payment in advance for larger or custom orders

These protections need to be set up properly. A clause copied from an overseas template may not do what you expect in New Zealand.

The key legal issue is whether your terms will actually bind the customer when payment trouble starts. A well written clause is much less useful if the customer can argue they never accepted it, or that another document overrides it.

Was there clear acceptance?

Your best position is to have clear evidence that the customer agreed to the credit terms before you supplied on credit. That might be a signed application form, a signed contract, or an electronic acceptance process that records date, time and version of terms.

Before you rely on a verbal promise, ask whether you could prove acceptance six months later if the account is overdue. If the answer is no, tighten your process now rather than after the dispute starts.

Do all your documents line up?

Many businesses use several documents in the same transaction. A quote may say one thing, a purchase order says another, and the invoice says something else. If those documents conflict, you can end up arguing about which terms apply.

Check consistency across:

  • credit application forms
  • terms of trade or supply terms
  • quotes and proposals
  • purchase order conditions
  • delivery dockets
  • invoices
  • email order confirmations

If a customer sends its own standard terms, do not assume yours automatically win. This is a common issue in contract review for B2B trade relationships.

Are your default rights reasonable and clearly drafted?

You can include rights that protect your business, but they should be clearly expressed and commercially sensible. Interest rates, cancellation rights and recovery cost clauses should not be buried or ambiguous.

If you want the right to stop work, stop deliveries or cancel future orders after non-payment, say so expressly. If your service is ongoing, also state what happens to work already performed and invoices already issued.

Your documents should reflect New Zealand law and business practice. Templates from Australia, the United Kingdom or the United States often use the wrong terminology, the wrong legislation, or assumptions that do not fit local enforcement steps.

For example, if you are relying on retention of title or other security wording, New Zealand personal property securities rules may be relevant. If you are collecting personal information from a sole trader or guarantor as part of the credit application, your privacy notice should also be fit for purpose under the New Zealand Privacy Act framework.

Are there any consumer law issues?

If you deal only with business customers, your terms can be tailored for B2B use. If you also supply consumers, extra care is needed because different consumer protection rules may affect what your terms can say and how they operate.

That can include issues around representations, unfair contract terms, and how you describe fees, charges or rights in your sales material. Your marketing and account application process should match what the contract says.

Legal terms are only one part of credit control. A strong document does not turn a poor account into a good payer.

Before you approve credit, think about:

  • how much exposure you are comfortable with for that customer
  • whether trade references or credit checks are appropriate
  • whether a guarantee is needed
  • whether staged payments would reduce risk
  • how often the credit limit should be reviewed

This is also a good point to make sure internal staff know who can approve credit variations. A common problem is that sales staff verbally agree to extended terms that do not match the written contract.

Common Mistakes With How to Set Clear Credit Terms

The most common mistake is treating credit terms as paperwork instead of a core cash flow tool. If the terms are vague, unsigned or disconnected from your invoicing process, they often fail when you need them most.

Relying on invoice fine print after the work is done

If you only send your terms on the back of an invoice, the customer may argue they never accepted them before the contract was formed. This is especially risky where the order was placed earlier by phone, email or purchase order.

The safer approach is to make your terms part of the account opening or order acceptance stage.

Using one payment clause for every type of job

A monthly trade account, a one-off project and a custom manufactured order do not carry the same risk. If you use the same terms for all of them, gaps appear quickly.

Custom work may need deposits and milestone payments. Ongoing supply may need a credit limit and suspension rights. Higher value goods may need security protections.

Leaving out who pays recovery costs

If the customer defaults, collection steps can be expensive. Many businesses assume they can simply add all costs to the account later, but that is much easier if the contract deals with it clearly from the start.

The clause should be drafted carefully and used consistently with your broader terms.

Failing to get guarantees when dealing with thinly capitalised companies

A customer company may have very few assets. If the business fails, an unpaid supplier can be left with little practical recovery even if the debt is legally clear.

For riskier accounts, a director guarantee may be worth considering before you sign or before you increase the credit limit.

Forgetting to reserve the right to suspend supply

Some businesses keep supplying a slow paying customer because the contract does not clearly allow suspension. That can increase the debt and weaken your negotiating position.

Your terms can state that overdue payment lets you pause deliveries, stop work, or require cash before further supply.

Not updating terms as the business grows

Founders often start with a short form agreement that worked when orders were small and customer relationships were informal. Once larger accounts arrive, those same terms may no longer cover guarantees, credit reviews, security interests or project-style billing.

Review your terms when your business model changes, when you move into larger contracts, or when payment disputes become more frequent.

Allowing inconsistent verbal side deals

A written contract can be undermined if staff make side promises such as “don’t worry about the due date” or “you can pay once your customer pays you”. Those comments can create confusion and sometimes real dispute about variation.

Train your team on what they can and cannot promise, and require approval for any payment plan or extension.

Ignoring record keeping

Even good terms are harder to enforce if your records are messy. Keep signed applications, accepted terms, delivery evidence, invoices, statements and account correspondence organised.

If a customer disputes the debt, your leverage often depends on how quickly you can show the contract, supply history and overdue balance in one clear file.

FAQs

Do I need a separate credit application, or are invoice terms enough?

A separate credit application is usually safer because it helps show the customer accepted the terms before credit was given. Invoice terms alone can be harder to rely on if they appear only after the contract was already made.

Can I charge interest on overdue invoices?

You can usually include default interest in your contract if the clause is clear and agreed upfront. The rate and wording should be commercially sensible and suitable for your circumstances.

Should I ask for a director guarantee?

That depends on the customer risk, the credit limit and whether the customer company has meaningful assets. For higher risk or higher value accounts, a guarantee can provide extra protection if it is properly drafted and signed.

Can I stop supplying a customer who is behind on payment?

You are in a much better position if your contract expressly gives you that right. Without a clear suspension clause, stopping supply may create its own dispute depending on the arrangement.

What if the customer sends its own purchase order terms?

Do not assume your terms automatically apply. Competing standard terms can create uncertainty, so the order process should clearly state which terms govern the transaction before you accept the order.
