Is A Quotation Legally Binding? In NZ

Yes, a quotation can be legally binding in New Zealand if it's clear enough to be an offer and the customer accepts it. The key rule is that a quote isn't automatically a contract, but it can become one through words, a signature, payment of a deposit, or conduct that shows acceptance.

That's why quote wording matters so much. If you send a quote that looks firm, the customer says "go ahead", and you start work, you may already have a binding contract even if nobody has signed a longer agreement.

Is A Quotation Legally Binding In New Zealand?

A quotation is legally binding in New Zealand when the usual contract elements are present: an offer, acceptance, an intention to create legal relations, and enough certainty about the key terms. In a business context, the law will often assume both sides intended to be legally bound unless the wording or surrounding circumstances point the other way.

In practical terms, a quote is more likely to be binding if it says exactly what you'll supply, what the customer will pay, when the work will happen, how long the quote is valid for, and how the customer can accept it.

A quote is less likely to be binding if it's only a rough indication of price, uses wording like "estimate only" or "subject to site inspection", or leaves important details open. The label matters, but it isn't everything. A document called a "quote" can still be non-binding if it's clearly conditional, and a document called an "estimate" can still create legal risk if it reads like a firm offer.

If you want to zoom out a little, a contract becomes binding when the key elements exist. If you need a plain-English breakdown of that bigger picture, it can help to start with What Makes A Contract Legally Binding.

What Makes A Quote A Legally Binding Contract?

Most quoting problems come down to whether the quote was just information or whether it was a genuine offer that could be accepted. The more specific and final your quote is, the easier it is for a customer to argue that accepting it created a contract.

The Quote Looks Like An Offer

A quote is more likely to be treated as an offer if it's addressed to a particular customer and includes enough detail for both sides to understand what is being agreed. For example, a quote for "website redesign services" is fairly vague. A quote for "five page WordPress website redesign, including homepage, about page, services page, contact page and blog template, for $6,500 plus GST" is much clearer.

Things that make a quote more likely to be an offer include:

• a clear scope of work or list of goods
• a fixed or clearly calculated price
• a validity period, such as "valid for 14 days"
• clear timeframes or delivery assumptions
• payment terms, including deposits or milestones
• wording that tells the customer how to accept

Things that make a quote less likely to be an offer include:

• wording such as "estimate only", "budget price" or "indicative pricing"
• conditions such as "subject to site inspection", "subject to supplier availability" or "subject to final approval"
• missing details about scope, timing or price
• a statement that no contract is formed until a separate agreement is signed

The Customer Accepts The Quote

Acceptance doesn't always need to be a handwritten signature. It can happen by email, text, online approval, paying a deposit, signing electronically, or giving instructions to begin work. If your quote says "payment of the deposit confirms acceptance", then a deposit payment can be strong evidence that the quote was accepted.

Where businesses get caught out is assuming that "we never signed anything" means "there's no contract". In many everyday business situations, the communications and conduct are enough.

The Terms Are Certain Enough

For a quote to be enforceable, it needs enough certainty for someone to work out what each party agreed to do. If your quote says "renovation works as discussed" or "marketing support for launch", you may end up with two very different versions of what that meant.

Useful details include scope, exclusions, customer responsibilities, timeframes, price, GST treatment, payment dates, cancellation rules and what happens if extra work is requested. For higher value or ongoing work, many businesses use a broader Service Agreement alongside quoting, so the quote sets out the commercial details and the agreement sets out the legal rules.

Is Accepting A Quote Legally Binding?

Accepting a quote can be legally binding if the quote is capable of acceptance and the acceptance matches the quote. If the customer says "yes, we accept", signs the quote, pays the deposit, or tells you to start on the terms you quoted, that may create a binding contract.

However, a response that changes the terms is usually not a clean acceptance. It may be a counter-offer. For example, if you quote $8,000 plus GST for a project and the customer replies, "Accepted, but only if you include an extra training session and reduce it to $7,500", they haven't accepted your original quote. They have proposed new terms for you to accept or reject.

Late acceptance can also be a problem. If your quote says it's valid for 14 days and the customer accepts it on day 25, you may be able to say the quote has expired. To avoid confusion, reply clearly, for example: "That quote has expired. We can honour the same price if you confirm by Friday" or "We'll need to re-quote because supplier costs have changed."

If you want acceptance to be unambiguous, make the process obvious. For example:

• "To accept this quote, please reply to this email with 'I accept'."
• "To proceed, please sign and return this quote by 5pm on 12 March."
• "Payment of the 30% deposit confirms acceptance of this quote and our terms."

It's also sensible to attach or link your standard terms at the same time as sending the quote. If your terms arrive after acceptance, it can be harder to show the customer agreed to them.

Is A Verbal Quote Legally Binding?

A verbal quote can be legally binding in New Zealand. A contract doesn't always need to be in writing. The real issue is proof: what was actually said, what was included, what price applied, and whether the customer accepted.

Verbal quotes are common in trades, consulting, event services and urgent supply arrangements. They can work for simple jobs, but they're risky where materials, labour, timelines or customer expectations might change.

If you give a quote over the phone or in person, send a short confirmation as soon as possible. It doesn't need to be complicated. For example:

"Confirming our discussion today: we'll supply and install three shelves in the reception area for $1,200 plus GST. This includes standard materials and installation during business hours. It excludes electrical work, wall repairs and after-hours work. Please reply 'accepted' if you would like us to proceed."

That kind of follow-up helps both sides. It reduces the risk of a customer later saying the quote included something extra, and it gives the customer a chance to correct anything before you start.

Quote Vs Estimate: Why The Label Matters But Is Not Everything

A quote is usually a firm price for a defined scope. An estimate is usually a best guess based on the information available at the time. That difference matters because customers often expect a quote to be honoured, while they expect an estimate to move if assumptions change.

For example, if you run a landscaping business and quote $4,800 plus GST to install a specified number of plants and pavers, the customer may reasonably expect that price to hold for that scope. If you estimate "around $4,800 plus GST, subject to final measurements and plant availability", you have built in more flexibility.

The label alone won't always decide the outcome. If you call something an estimate but write it like a fixed quote, include a clear scope and price, and ask the customer to accept, it may still create a binding agreement. If you genuinely need flexibility, make the assumptions clear.

Helpful estimate wording can include:

• "This is an estimate only, based on the information currently available."
• "Final pricing is subject to site inspection and written confirmation."
• "Additional work outside the scope will be charged at $X per hour plus materials."
• "Supplier price increases, freight changes or stock availability may affect final pricing."

If GST applies to your business, be clear whether prices are GST inclusive or plus GST. If you're unsure about your GST registration or invoicing obligations, check with your accountant or Inland Revenue.

Common Scenarios Where Quotes Become Problems

Quote problems usually start because the assumptions weren't written down. These are the situations that tend to cause trouble for small businesses.

The Customer Changes The Scope

A customer accepts your quote, then asks for extra work, faster delivery or a different product. If your quote doesn't deal with variations, you may feel pressured to absorb the extra cost.

Your quote should say that extra work must be approved in writing, may change the price, and may change the timeline. It also helps to include an hourly rate or method for calculating additional costs.

You Start Work Before Acceptance Is Clear

This often happens when you're trying to be helpful or move quickly. The risk is that you later disagree about what was approved. Before starting, try to get at least a short written confirmation, a deposit payment, or an email reply that clearly says the customer accepts the quote.

The Customer Says The Quote Included More

Customers often focus on the outcome they want, while businesses focus on the specific work priced. That gap can create frustration. Include exclusions as well as inclusions. For example, "copywriting not included", "permit fees not included", "installation excludes after-hours access" or "third party software subscriptions are billed separately".

The Customer Is A Consumer

If you supply goods or services to consumers, the Consumer Guarantees Act 1993 may apply. Services must generally be carried out with reasonable care and skill, be fit for purpose where the customer relies on your skill or judgement, and be completed within a reasonable time if no timeframe is agreed. Goods also come with guarantees, including acceptable quality and fitness for purpose.

The Fair Trading Act 1986 can also apply to the way you describe your prices, discounts, results and scope. Don't use a quote to promise something you can't deliver, and be careful with headline prices if important fees or exclusions are hidden in the fine print.

Worked Example: When A Quote Becomes Binding

Imagine you run a small digital agency in Wellington. You email a cafe owner a quote for a new website. The quote says:

• five page website design and build
• $6,000 plus GST
• 40% deposit payable before work starts
• two rounds of design revisions included
• copywriting, photography and third party software costs excluded
• quote valid for 14 days
• payment of the deposit confirms acceptance

The cafe owner pays a $2,400 deposit plus GST on day 10 and emails, "Excited to get started." At that point, there's a strong argument that the quote has been accepted and a binding contract exists for the website project on those terms.

Two weeks later, the cafe owner asks you to add online ordering, write all the website copy and organise a photographer, but says it should still be included in the $6,000. Because your quote clearly excluded copywriting, photography and third party software, and limited the scope to five pages, those extras sit outside the original quote.

A good variation process lets you respond professionally: "Those items are outside the accepted quote. We can add online ordering for $1,500 plus GST, copywriting for $900 plus GST and photography coordination at $150 per hour. If you would like to proceed, please reply confirming acceptance of this variation."

Now compare that with a vague quote that simply said "new website, $6,000". The outcome becomes much messier because both sides may have a reasonable but different understanding of what the price included.

Acceptance Of Quote Wording And Quote Checklist

Your quote doesn't need to read like a 30 page contract. It does need to make the deal clear. A simple step-by-step process can prevent most quote misunderstandings before they start.

1. Identify The Customer: Use the correct legal or trading name, contact details and date.
2. Describe The Scope: Set out the goods or services, deliverables, quantities and project stages.
3. List Assumptions And Exclusions: Say what you have relied on and what isn't included.
4. State The Price: Say whether the price is fixed, estimated, hourly, GST inclusive or plus GST.
5. Set Payment Terms: Include deposits, milestone payments, due dates and invoicing details.
6. Include Timing: State expected delivery dates and any customer actions needed to meet them.
7. Deal With Variations: Explain how changes are approved and charged.
8. Add A Validity Period: Say when the quote expires.
9. Explain Acceptance: Tell the customer exactly how to accept the quote.
10. Attach Your Terms: Make sure any standard terms are provided before or at the time of acceptance.

Useful acceptance wording includes:

• "To accept this quote, please sign below and return a copy by email before the expiry date."
• "By replying 'accepted', you confirm that you accept this quote and our attached terms of trade."
• "Payment of the deposit confirms acceptance of this quote, including the scope, exclusions, payment terms and variation process."
• "No work will begin until we have received written acceptance and the deposit."

A lawyer should tailor your quote template to your business, especially if you deal with recurring work, high value projects, deposits, subcontractors, intellectual property or customer data. If you're looking across your broader business compliance, a Legal Health Check can also help you spot areas that may need attention.

If you're running ongoing services or supply, your broader Terms Of Trade can help standardise payment rules across all customers, rather than rewriting them in every quote.
