Can you update your client terms so you can take deposits, charge late fees and pause work if a client doesn't pay? Yes, you usually can - but the wording needs to be clear, fair and agreed before you start the work.
Late payment is one of the most frustrating cashflow problems for service businesses. You've done the work, paid your team or contractors, and then you're left chasing invoices instead of getting on with the next job.
The good news is that your payment terms can do a lot of the heavy lifting. They can set expectations early, give you practical options when invoices go overdue, and reduce the chance of awkward arguments later.
What Should Your Payment Terms And Conditions Cover?
Your payment terms should cover when you get paid, how you get paid, what happens if payment is late and what rights you have if the client doesn't pay. The goal is to make payment feel like a normal part of the project, not a difficult conversation at the end.
For a service business, your payment terms usually sit in one of these documents:
- Service agreement: useful for larger projects, ongoing retainers or higher-risk work.
- Client terms and conditions: useful when you want one set of standard terms for many clients.
- Quote or proposal terms: useful for smaller jobs where the client accepts a quote before work starts.
- Statement of work: useful when the commercial details change project by project, but your main terms stay the same.
Try not to rely on invoice wording alone. If your client only sees your late fee or deposit clause after you've already done the work, you may struggle to show they agreed to it.
Your terms should be accepted before you start. That might be by signing a service agreement, ticking an online checkbox for online services, accepting a quote that links to your terms, or confirming in writing that they agree.
A strong payment clause usually answers these questions:
- What amount is payable?
- Is there a deposit, milestone payment, retainer or final invoice?
- When is each payment due?
- Is GST included or added?
- What payment methods do you accept?
- What happens if the client disputes part of an invoice?
- Can you charge interest, admin fees or recovery costs?
- Can you pause work, withhold deliverables or end the arrangement?
Can You Ask For A Deposit Before Starting Work?
Yes, you can ask for a deposit before starting work, as long as your deposit clause is clear and not misleading or unfair. Deposits are common in service businesses because they help cover upfront planning, materials, booking time and the risk of cancellation.
Your deposit clause should spell out:
- the deposit amount, for example 30% or a fixed dollar amount
- when the deposit is due, for example before work starts
- whether the deposit is refundable, partly refundable or non-refundable
- what happens if the client cancels or delays the project
- what happens if you can't provide the service
- whether the deposit is applied to the final invoice
Be careful with the words non-refundable deposit. In New Zealand, the Fair Trading Act 1986 can apply if your wording or sales process misleads a client about what they're paying for. The Consumer Guarantees Act 1993 may also matter if you're supplying services to a consumer.
A blanket rule that every deposit is non-refundable in every situation can be risky. For example, if you cancel the job and haven't incurred costs, keeping the whole deposit may be hard to justify.
A more balanced clause might say the deposit is used to secure your time and cover initial work, and that if the client cancels, you may keep an amount that reasonably reflects work done, costs incurred and time set aside. The exact wording depends on your business model, so it's worth getting it tailored before you use it.
Can You Charge Late Fees Or Interest In New Zealand?
Yes, you can charge late fees or interest in New Zealand if the client agreed to them and the charges are reasonable. There isn't a general automatic right to add a late fee to every unpaid business invoice just because it's overdue.
A late payment clause usually works best when it separates three different things:
- Interest: a percentage charged on overdue amounts, such as a monthly rate.
- Admin fees: a fee for the internal cost of chasing late payment, if it reflects a real cost.
- Recovery costs: costs you incur because of the non-payment, where your terms allow recovery.
New Zealand contract law can treat some excessive late payment charges as penalties. In plain English, if a charge is out of proportion to your legitimate business interest in being paid on time, it may not be enforceable.
That doesn't mean you can't protect yourself. It means the clause should be commercially sensible and written in a way that connects the charge to the impact on your business.
A Worked Example
Say Maia runs a Wellington design studio. She agrees to a $4,000 plus GST branding project with a small retailer.
- The client pays a 40% deposit of $1,600 plus GST before work starts.
- A second payment of $1,200 plus GST is due when first concepts are delivered.
- The final $1,200 plus GST is due 7 days after final files are ready.
- The terms say overdue amounts may attract interest of 1.5% per month, plus a reasonable admin fee if reminders are needed.
If the final invoice is one month overdue, the interest on $1,200 would be $18. If Maia's terms were accepted before work started, and the admin fee reflects the real cost of chasing payment, she has a much stronger position than if she tried to add those charges for the first time after the invoice became overdue.
Can You Pause Work If A Client Doesn't Pay?
Yes, you can usually pause work for non-payment if your contract gives you that right and you follow the process in the clause. Without that wording, pausing work can create its own risk, especially if the client says you breached the agreement first.
A good suspension clause should explain:
- when an invoice becomes overdue
- whether you need to send a reminder or written notice first
- how many days the client has to fix the non-payment
- what work you can pause
- whether deadlines move while work is paused
- whether you can charge extra costs caused by the delay
- when you can restart or end the services
For example, your terms might say that if an invoice remains unpaid 7 days after the due date, you can give written notice requiring payment within 3 business days. If payment still isn't made, you may pause the services and extend any delivery dates by the period of delay.
That type of process is often more practical than immediately stopping work on the due date. It gives the client a clear warning, creates a paper trail and helps you look reasonable if there's later disagreement.
You should also think about deliverables. If you create reports, designs, software, marketing assets or other work product, your terms can say you don't have to release final deliverables until all amounts due have been paid. If intellectual property rights are involved, your IP clause should line up with your payment clause.
What Fair Trading Act Risks Should You Watch For?
You need to make sure your payment terms are clear, accurate and fair, because the Fair Trading Act 1986 can apply to how you present and enforce them. This matters whether your clients are consumers or other businesses.
The Fair Trading Act prohibits misleading and deceptive conduct in trade. So, if your proposal says one thing and your payment terms say another, that can create problems. The same goes for hidden fees, unclear cancellation charges or a sales conversation that downplays a strict clause in your written terms.
The unfair contract terms rules can also apply to standard form consumer contracts and small trade contracts. A small trade contract is generally a business-to-business standard form contract where the expected annual trading relationship is $250,000 or less including GST when the contract is entered into.
A term may be at risk if it creates a major imbalance, isn't reasonably necessary to protect your legitimate interests, and would cause detriment if relied on. For payment terms, higher-risk clauses include ones that let you:
- change prices without a clear reason or notice process
- keep all prepaid amounts in every cancellation scenario
- charge very high late fees that don't match your likely loss or costs
- pause or cancel services immediately without giving the client a fair chance to pay
- decide unilaterally that work is complete and full payment is due, with no sensible dispute process
If you deal with consumers, the Consumer Guarantees Act 1993 may also apply to the quality, timing and care of your services. If you deal with other businesses, you may be able to contract out of some Consumer Guarantees Act obligations, but only where both parties are in trade, the wording is in writing and it's fair and reasonable.
How Do You Put Payment Terms Into Your Documents?
You should put your payment terms where the client will see and accept them before the work begins. The cleanest setup is usually a short commercial schedule plus a set of standard terms.
Templates can be a helpful starting point, but they often miss the details that make payment clauses work in real life. A clause for a wedding photographer won't suit a builder, software developer, consultant, cleaner, home services business or marketing agency without changes.
Fill-In Outline For Service Payment Terms
Use this outline as a drafting checklist, not as a finished document. Your lawyer or legal team should tailor the wording before you use it with clients.
- Parties: write the correct legal names, trading names and NZBNs where relevant.
- Scope Of Services: describe exactly what you're providing and what's excluded.
- Fees: state fixed fees, hourly rates, retainers or project pricing, and whether GST is included.
- Deposit: set the amount, due date, refund rules and cancellation consequences.
- Milestones: list each payment trigger, such as booking, draft delivery, approval or completion.
- Invoice Terms: say when invoices are issued and when they're due, for example 7 or 14 days from invoice date.
- Payment Methods: include bank transfer, card or direct debit details, and who pays any processing fees.
- Disputed Invoices: require the client to raise genuine disputes promptly and pay any undisputed amount on time.
- Late Payment: set any interest, admin fees and recovery cost wording in a reasonable way.
- Suspension Of Services: explain the notice process before you pause work for non-payment.
- Withholding Deliverables: say when final files, access, reports or licences are released.
- Ending The Services: cover what happens to unpaid fees, deposits and work in progress if the arrangement ends.
Your invoices should then match your contract. Include the right entity name, invoice date, amount, due date, payment details and any GST information required for your business. If you're GST registered, check the Inland Revenue rules for taxable supply information so your invoices meet the current requirements.
What Should You Do If A Client Is Already Overdue?
You should first check the contract, invoice and acceptance trail before you add fees or pause work. What you can do depends on what the client agreed to and how clearly your terms were incorporated.
Start with a calm, practical process:
- Check The Due Date: confirm the invoice is actually overdue under the agreed terms.
- Review The Contract: look for clauses on interest, late fees, suspension, deliverables and termination.
- Save The Paper Trail: keep the signed agreement, accepted quote, emails, reminders and proof of delivery.
- Send A Clear Reminder: state the amount, invoice number, due date and payment details.
- Give Notice Before Pausing: if your terms require notice, follow that process carefully.
- Avoid New Work Without Payment: consider requiring payment upfront for any further work.
If your current terms don't give you the rights you need, be careful about changing the rules mid-project. You can ask the client to agree to updated terms, but you generally can't impose new late fees or suspension rights retrospectively without agreement.
For future clients, the better move is to update your documents now. Clear payment terms won't prevent every late payer, but they put you in a much stronger position and make your process easier to follow when cashflow gets tight.
Key Takeaways
- Payment terms work best when clients accept them before you start the services, not just when they receive an invoice.
- You can usually take deposits, but the refund rules should be clear, fair and matched to your real costs and booking risk.
- Late fees and interest need to be agreed upfront and should be reasonable, not punitive.
- A suspension clause can let you pause work for non-payment, but it should include a sensible notice process.
- The Fair Trading Act 1986 can apply to hidden fees, harsh standard terms and misleading payment promises.
- Your service agreement, quote, invoices and deliverable release process should all say the same thing.
