How to Set Up Credit Terms the Right Way for New Zealand Businesses

Offering credit can help you win larger clients, smooth out repeat orders, and keep cash flowing across a growing customer base. It can also create serious problems if your paperwork is vague, your payment process is loose, or you rely on a handshake instead of clear written terms. New Zealand businesses often make the same mistakes: they extend credit without checking who they are really contracting with, they copy generic payment clauses that do not match their business, or they assume a quote or invoice is enough to recover overdue amounts later.

The main legal risk is not just late payment. It is finding out, after goods are supplied or services are delivered, that your terms do not clearly cover due dates, default interest, collection costs, ownership of goods, disputes, or personal guarantees. That is where unpaid debt becomes expensive and hard to chase. This guide explains what proper credit terms should cover, what to check before you sign or accept a customer on account, and the common drafting mistakes that leave businesses exposed.

Overview

Well-drafted credit terms set the ground rules for payment, risk, and recovery before you extend credit to a customer. They help your business stay consistent, reduce disputes, and improve your position if a customer pays late or defaults.

• Confirm who the customer is, including the correct legal entity and trading details
• Set clear payment periods, invoicing rules, and overdue consequences
• Decide whether you need a retention of title clause, security, or a personal guarantee
• Make sure your terms are properly accepted before you supply goods or services
• Check whether your collection, cancellation, and suspension rights are actually enforceable
• Align your credit application, terms of trade, and invoices so they do not contradict each other

What This Means For Your Business

Setting up credit terms the right way means documenting exactly when you will supply, when the customer must pay, and what happens if they do not. It is not just an admin form. It is a contract framework that protects your cash flow and gives you a stronger legal position if things go wrong.

For many SMEs, credit is offered casually. A customer asks for 20th of month payment, a sales manager agrees, and the first invoice goes out with a short note at the bottom. That approach can work until a customer disputes pricing, refuses to pay collection costs, or enters financial distress.

Good credit terms usually sit across several documents. These might include a credit application, terms of trade, quote acceptance wording, purchase order process, and invoice conditions. The key is consistency. If one document says payment is due in 7 days and another says 30 days, you have created room for argument.

What credit terms usually cover

At a practical level, your credit terms should deal with the commercial points that matter most in day-to-day trading, including:

• who the customer is and who is authorised to place orders
• the credit limit and whether you can vary or withdraw it
• when payment is due
• how invoices are issued and how billing disputes must be raised
• interest, default fees, or recovery costs on overdue amounts
• whether title to goods stays with you until payment is made
• your right to suspend future supply if invoices are overdue
• what warranties, exclusions, or liability clauses apply, where legally permitted
• the circumstances in which you can cancel the arrangement
• which law applies and where disputes are handled

If you supply goods, a retention of title clause can be especially important. This says ownership does not pass to the customer until you have been paid. In the right circumstances, that may improve your position if the customer defaults. But the clause needs to be drafted properly and supported by your wider contracting process. In some cases, registration steps under the Personal Property Securities regime may also be relevant if you are taking a security interest.

Why proper acceptance matters

Your terms only help if they become part of the contract. This is where founders often get caught. They have a well-written set of terms on file, but they never actually ensured the customer agreed to them.

Before you sign a contract, or before you accept the provider's standard terms in reverse, think about how your own terms are accepted. A signed credit application is usually stronger than terms printed on the back of an invoice after the work is done. If orders are placed by email or through a sales portal, the contracting flow needs to make it clear when the customer is agreeing to the terms.

This becomes even more important where larger customers issue their own purchase orders with competing conditions. If both sides send standard terms, there can be a dispute about which terms govern the deal. That issue should be sorted out upfront, not after a payment default.

Why New Zealand context matters

New Zealand businesses also need to draft credit terms with local law in mind. General contract law principles still apply, but so do local rules affecting fair dealing, consumer transactions, electronic contracting, and security interests. If you deal with consumers as well as business customers, some clauses that seem standard in business-to-business trading may not work the same way in a consumer context.

For example, your marketing and billing practices still need to comply with the Fair Trading Act. If you are collecting personal information through a credit application, the Privacy Act may affect what you collect, why you collect it, and how you store and disclose it in your privacy notice. If you are supplying services to consumers, rights under the Consumer Guarantees Act can also limit how far your terms can exclude liability. That means a one-size-fits-all terms sheet can be risky.

Legal Issues To Check Before You Sign

The safest time to sort out credit terms is before you extend credit, before you deliver the goods, and before you rely on a verbal promise about payment. Once a customer account is already running, changing the legal position becomes harder.

1. Identify the correct customer entity

You need to know exactly who is getting credit. Many debt recovery problems begin with the wrong customer name on the form. A trading name is not enough on its own if the actual counterparty is a company, sole trader, or partnership with different legal status.

Check details such as:

• full legal name
• NZBN if available
• Companies Office registration details if the customer is a company
• registered office or principal place of business
• director or owner details where relevant
• billing contact and authorised account contact

If the customer is a small company with minimal assets, you may also want a director's personal guarantee. That can improve your recovery options, but it should be drafted carefully and signed correctly.

2. Set clear payment timing

Your payment clause should be precise, not conversational. “Payment due monthly” can create argument. “Payment due on the 20th of the month following invoice date” is clearer, but only if your invoicing process supports it.

Think about:

• when an invoice is deemed received
• whether deposits or progress payments apply
• whether payment is due from invoice date, statement date, or month end
• what happens if there is a genuine billing dispute
• whether set-off is allowed

If your staff negotiate custom arrangements for major clients, make sure those special terms are formally recorded. Informal side deals often undermine your standard terms.

3. Decide what security you need

Not every customer needs the same credit risk treatment. A long-standing commercial customer with stable payment history may not need a guarantee. A new customer ordering high-value stock on 45 day terms may be different.

Your options may include:

• a lower credit limit
• cash on delivery for initial orders
• a deposit
• a retention of title clause
• a personal guarantee
• security interest wording and related registration steps where appropriate

The right structure depends on what you supply and how exposed you are if the customer fails to pay.

4. Make sure your default clauses are realistic

You can include consequences for late payment, but they need to be sensible and clearly drafted. Default interest, administration charges, and debt recovery costs are common, but they should not be so aggressive or vague that they create their own dispute.

Before you sign, check whether the terms say:

• when interest starts running
• how interest is calculated
• whether recovery costs are recoverable on a solicitor-client basis or another defined basis
• whether you can suspend supply while money is overdue
• whether you can cancel undelivered orders

A clause that sounds tough but is poorly drafted may not give you much practical leverage.

5. Match your terms to your supply model

Credit terms should fit how your business actually trades. Goods suppliers, wholesale businesses, contractors, and service providers often need different wording.

For example, if you supply physical stock, title and risk clauses matter. If you provide ongoing services, milestone invoicing, acceptance criteria, and termination rights may be more important. If your team accepts urgent orders by phone, your acceptance process needs to cover that reality.

6. Check privacy and credit information handling

If your credit application collects personal information, especially director information, guarantor details, or credit references, you need to handle that information properly. The form should explain why the information is collected and how it may be used and disclosed.

This can include uses such as:

• assessing a credit application
• contacting trade references
• administering the account
• recovering overdue amounts
• updating records

Your internal handling matters too. There is little value in a carefully written form if information is then stored loosely or shared without proper control.

7. Watch out for consumer and fair trading issues

If you deal mainly with businesses, your terms can usually be tailored for business-to-business contracting. But if some customers are consumers, you should be more careful. Rights under consumer law may override broad exclusion clauses, and statements made during the sales process can still create liability if they are misleading.

That means your sales team should not promise one thing while your credit terms say another. The written contract helps, but it will not always erase a misleading representation made earlier.

Common Mistakes With How to Set Up Credit Terms the Right Way

The most common mistakes are not dramatic. They are small process gaps that leave a business exposed when a customer stops paying. Fixing them early is usually much cheaper than arguing about them later.

Relying on invoices as the only contract document

An invoice is mainly a billing document. It can support your position, but it is a weak place to introduce legal terms for the first time after supply has already happened.

If your only payment wording appears on invoices sent after the order is accepted, a customer may argue those terms were never agreed. Stronger practice is to have signed or clearly accepted terms in place before ongoing trade starts.

Using copied terms that do not match your business

Many businesses start with terms borrowed from a supplier, industry contact, or old template. The wording often looks professional, but it may not fit how orders are placed, how invoices are issued, or what you actually supply.

This creates problems such as:

• references to goods when you mainly provide services
• retention of title clauses where no physical goods are supplied
• delivery clauses that conflict with your freight model
• consumer exclusions used in mixed consumer and business transactions
• default fees that are not clearly defined

Generic terms also tend to miss current process details, such as digital acceptance methods or online ordering workflows.

Failing to verify who has authority

A customer contact may place orders, but that does not always mean they had authority to bind the business to a credit arrangement or guarantee. This issue often appears when a company later says the signatory was not authorised.

Before you rely on a signed application, check who signed, what they signed on behalf of, and whether a guarantee was signed in a personal capacity where intended.

Allowing exceptions without documenting them

Founders often make commercial exceptions for good customers. That is normal. The problem comes when those exceptions are agreed casually and never written down properly.

Examples include:

• extending payment from 14 days to 45 days
• waiving late fees
• approving orders over the credit limit
• agreeing that disputed items can hold up the whole account

If you make an exception, document it clearly and make sure it only applies to that account or transaction.

Forgetting to review terms as the business grows

Credit terms that worked when you had five customers may not suit a larger operation with multiple sales channels, account managers, and higher average order values. This is where founders often get caught. The business changes, but the paperwork and approval process stay the same.

Review your terms if you:

• move from one-off jobs to ongoing accounts
• start supplying higher-value stock
• take orders through new channels
• expand into different customer types
• introduce subscriptions, staged work, or custom orders

A contract review is also sensible if you are seeing recurring disputes about payment timing, damaged goods, credits, or collection costs.

Assuming a guarantee solves everything

A personal guarantee can be useful, but it is not a magic fix. If it is drafted poorly, signed incorrectly, or not supported by the main credit terms, enforcement can still be messy. It can also complicate the relationship if introduced late.

The better approach is to treat guarantees as one part of your broader credit control system, alongside due diligence, sensible limits, clear terms, and consistent acceptance procedures.

FAQs

Do I need written credit terms if I already send invoices with payment dates?

Usually yes. Invoices help with billing, but they are not a substitute for properly accepted contract terms. Written credit terms give you clearer rights around late payment, suspension, guarantees, and recovery costs.

Can I charge interest on overdue invoices in New Zealand?

You generally can if your contract clearly allows it. The clause should state when interest applies and how it is calculated. Vague wording can make recovery harder.

Should every customer sign a credit application?

Not always, but businesses that offer account facilities often benefit from one. It helps verify the customer entity, collect trading details, and record acceptance of your terms before you supply on credit.

What is a retention of title clause?

It is a clause saying you keep ownership of goods until you have been paid. It can be useful for goods suppliers, but it needs to be drafted properly and may need to work alongside personal property securities steps.

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

Often yes, if your terms clearly give you that right. Without a clear suspension clause, stopping supply may create its own dispute, especially if there is an ongoing contract or committed order pipeline.
