You’ve done the proposal, had the calls, agreed on price and scope, and you’re ready to start. Then the client says: “Looks good - we’ll sign it shortly.”
So do you wait? Or can you start work (and still be protected) even if the contract hasn’t been signed yet?
This is one of the most common contract questions we hear from New Zealand business owners - especially consultants, agencies, tradies, SaaS providers and service-based businesses where work starts quickly and timelines are tight. This 2026 update reflects how contracts are actually being formed day-to-day in modern businesses (think: email approvals, online platforms, and “please proceed” messages) and what you should do to reduce the risk of doing unpaid or disputed work.
Let’s break it down in plain English.
Is A Contract Still Binding If It’s Not Signed?
In New Zealand, a signature is not always required for a contract to be legally binding.
What matters is whether the key elements of a contract exist. Generally, those include:
- Offer (one party offers specific terms)
- Acceptance (the other party accepts those terms)
- Consideration (something of value is exchanged - usually payment for goods/services)
- Intention to create legal relations (it’s meant to be a real business arrangement, not a casual chat)
- Certainty of terms (the essential terms are clear enough to enforce)
That means you can sometimes have a binding agreement even if:
- the client never signed the PDF
- the “contract” is spread across emails and messages
- work started before signatures were finalised
But here’s the catch: being “able to argue you have a contract” is not the same as having a contract that’s easy to enforce. Unclear acceptance, missing terms, and scope creep can turn a simple payment issue into a long, expensive dispute.
So while you don’t always need a signed contract, you do need a clear agreement - and you need to be able to prove it.
When A Signature Usually Matters More
There are situations where you should be extra cautious about starting before signing, including:
- High-value projects where the risk of non-payment is significant
- Long-term engagements where the scope may evolve over time
- Projects requiring upfront costs (materials, subcontractors, software licences, advertising spend)
- Contracts with complex terms like limitation of liability, indemnities, IP ownership, or termination rights
- Where the client is already “negotiating hard” on terms - that can be a warning sign they may dispute later
If your contract includes important risk protections (like liability caps or IP clauses), you usually want confidence those terms were accepted before you do any meaningful work.
What Counts As “Acceptance” If The Client Hasn’t Signed?
Acceptance doesn’t need to look like a signature. It can show up through words, actions, or a pattern of behaviour.
Some common examples in business:
- The client emails “Approved, go ahead” or “Looks good - please proceed.”
- The client pays a deposit or the first invoice.
- The client gives you access to systems, branding files, or a worksite.
- The client attends kick-off meetings and starts requesting deliverables.
- The client uses what you deliver (e.g. publishes the website, runs the ads, uses the report).
That said, acceptance needs to be acceptance of your terms - not just acceptance that you’re “doing something”. If you emailed a contract and they replied “Ok”, that might help. But if there were multiple versions or ongoing negotiation, it can be harder to show which terms were agreed.
Watch Out For “Subject To Contract”
If the discussions (or proposal) say the arrangement is “subject to contract”, “pending signature”, or “not binding until signed”, that can strongly suggest there’s no binding agreement until the formal contract is executed.
This is where businesses get caught out: you start work because it feels agreed, but the paper trail suggests the parties intended to only be bound once signing happened.
If you’re seeing “subject to contract” language, treat it as a big sign to pause and tighten up the process.
Should You Start Work Before The Contract Is Signed?
This is the practical question - and the answer depends on your risk tolerance, your cashflow, and how confident you are that you can prove the agreed terms.
If you’re deciding whether to start work before signing, ask yourself:
- Do I have clear written acceptance of the price, scope and timeline?
- Have I clearly communicated what happens if they cancel?
- Do I have a payment trigger I can enforce? (deposit, milestone, upfront invoice)
- Have we agreed who owns the IP created?
- Is there a realistic chance the client will dispute the scope later?
As a general rule: if the project is small and low risk, you may choose to start with strong written confirmation and an upfront payment. If it’s higher value or higher risk, it’s usually worth waiting until signing is done (or at least until you have clear acceptance plus payment).
A Good Middle Ground: “Start Work” Confirmation
If the client is slow to sign but you don’t want to lose momentum, you can send a short email that does two things:
- confirms the key commercial terms (scope, price, start date, payment timing)
- states you will proceed on the basis the attached agreement applies
For example (tailor to your business):
Email example:
“Thanks - we’ll schedule work to commence on Monday. To confirm, we’ll proceed on the basis of the attached agreement (including payment terms and scope). If you’d like any changes, please let us know before we start. Otherwise, please reply ‘confirmed’ so we can lock this in.”
This won’t replace a properly signed contract in every situation, but it can dramatically improve your position compared to starting with nothing but a verbal “yes”.
The Real Risk: It’s Not Just “No Signature” - It’s Missing Protections
Most disputes don’t happen because there was no signature. They happen because the agreement wasn’t clear, or the business didn’t have the right protections in place.
Here are the big contract risk areas we see when work starts early.
1. Scope Creep And “I Thought That Was Included”
If the scope isn’t crystal clear (or is buried in informal messages), you can end up doing extra work without extra pay.
A strong contract should clearly cover:
- what is included (deliverables, revisions, response times)
- what is excluded
- how variations are priced and approved
When this is missing, “we never agreed to pay for that” becomes a common line - even when you feel the work was obviously requested.
2. Payment Disputes And Late Payments
If payment terms aren’t agreed and accepted upfront, you’re relying on “what’s fair” - and that’s often where disputes live.
At minimum, you want clarity on:
- deposit or upfront payment requirements
- invoice schedule (milestones, weekly, monthly)
- payment due dates
- what happens if payment is late (pause rights, interest, debt recovery costs)
If you’re providing services, having well-structured Service Agreement terms can make a big difference - not just legally, but operationally (everyone knows how the project will run).
3. “Who Owns The Work?” (IP Ownership)
This is a huge one for creatives, developers, marketers, consultants, and product businesses.
If you create work (designs, code, training materials, copy, processes), the default legal position isn’t always what business owners assume. Ownership can depend on the circumstances and what was agreed.
Your contract should clearly state:
- what IP you retain (templates, pre-existing tools, know-how)
- what IP transfers to the client (and when - often after full payment)
- any licence terms (e.g. client can use, but not resell or modify)
If you’re engaging contractors to do work for you, you also want to ensure your agreements cover IP properly, because otherwise you might not actually own what you think you’re selling. This is where a fit-for-purpose Sub-Contractor Agreement can be critical.
4. Liability And “We’re Holding You Responsible For Everything”
Many businesses start work thinking the main risk is non-payment. But liability risks can be bigger.
Without agreed limitations, you may be exposed to claims like:
- alleged loss of profits
- reputational damage
- third-party claims (e.g. customer complaints tied to your work)
- unexpected rectification costs
A properly drafted contract will typically deal with limitation of liability, exclusions, and dispute processes. If the client hasn’t signed, you may find it harder to rely on those protective clauses - even if you “sent them through”.
5. Cancellation And Termination Confusion
Clients change their mind. Budgets get cut. Internal stakeholders change. If you’ve started work and there’s no agreed termination clause, you can end up arguing about:
- whether the client can cancel at all
- whether you’re entitled to be paid for work already performed
- whether you can keep the deposit
- handover obligations and access removal
Even a short contract should be clear about how termination works. If you’re ending a relationship (or the other side is), the details matter - and it’s easier to enforce them when the contract was clearly accepted.
How To Protect Yourself If You Need To Start Work Fast
Sometimes, you can’t wait. The client has a launch date, your team is booked, and you’ll lose the job if you push too hard for signature first.
Here are practical ways to reduce risk (without killing the momentum).
Use A “Deposit Before Work Starts” Rule
If you do one thing, make it this: don’t start meaningful work until the deposit is paid.
Payment is powerful evidence of acceptance, and it also reduces cashflow risk if the project goes sideways early.
If your business is more productised (e.g. fixed packages), you might take full payment upfront. If your projects are large, you might use staged milestones.
Keep Your Contracting Process Simple
Clients delay signing when the process is clunky or confusing.
Some ways to reduce friction:
- send a clean, final version (avoid “v7_final_FINAL2.pdf”)
- use e-signing tools
- highlight the fields they need to complete
- include a short “how to proceed” line in the email
The easier you make it, the faster it gets done.
Make Sure Your Contract Matches How You Actually Work
A contract that doesn’t match your real process tends to get ignored. Then, when a dispute happens, it’s harder to rely on.
For example, if your business communicates primarily through Slack or email, ensure your contract:
- explains how instructions and approvals happen
- sets response times or assumptions
- covers what counts as “client approval”
If you’re using terms and conditions on a website (especially for online service sign-ups), it may be more appropriate to use website-based terms rather than a “traditional” PDF contract. In those cases, having solid Website Terms and Conditions can help ensure users are clearly on notice of your rules.
Be Clear About Privacy If You’re Handling Client Or Customer Data
Many service providers end up handling personal information: customer lists, email addresses, health info, or employee data.
Even if the contract isn’t signed yet, you should still be thinking about your obligations under the Privacy Act 2020 - including collecting, using, storing and disclosing personal information appropriately.
If you collect personal information through your website or platform, having a properly drafted Privacy Policy is one of the easiest “from day one” protections you can put in place.
Don’t Rely On Generic Templates For High-Risk Work
It’s tempting to grab a template and hope for the best - especially when you’re busy and just want to get the project moving.
The problem is that templates often:
- don’t reflect NZ law (or NZ commercial norms)
- miss key clauses you actually need
- include clauses that don’t match your business (and can backfire)
- don’t deal with your specific risks (especially IP and liability)
Contracts work best when they’re tailored to your service, your pricing model, and your real-world delivery process.
Key Takeaways
- You don’t always need a signature for a contract to be binding in New Zealand - but you do need clear evidence that the client accepted your terms.
- Email approvals, payments, and the client’s conduct can sometimes show acceptance, but it’s much harder to enforce unclear or incomplete agreements.
- The biggest risk in starting work early is often missing protections around scope, payment, IP ownership, liability and termination - not just the lack of a signature.
- If you need to move quickly, reduce risk by getting a deposit paid, confirming acceptance in writing, and keeping your contracting process simple and consistent.
- If your work involves creating deliverables or using contractors, make sure IP ownership is dealt with properly (both with the client and inside your team).
- If you collect or handle personal information, you should still meet your Privacy Act obligations and have the right privacy documents in place from day one.
