Customer Terms for NZ Quantity Surveying Firms

If you run a quantity surveying firm, your customer terms do more than set out fees. They shape what you are actually promising, when you get paid, what happens if the scope grows, and how much risk you are carrying if a client later says your advice caused them loss. Many firms get caught by three common mistakes: relying on a short quote with no proper terms, accepting broad liability for project outcomes they do not control, and leaving variations so vague that fee disputes become almost inevitable. Another common problem is treating all instructions as if they are the same, even though a bank valuation support brief, a cost estimate for a developer, and a progress claim review can involve very different risks.

This guide explains what a strong set of customer terms for quantity surveying firm work should cover in New Zealand, which legal issues matter before you sign, and where firms most often get exposed. If you are reviewing your own standard terms or a client's consultancy agreement, the key is to make the commercial deal clear before you rely on a verbal promise or start work.

Overview

Good customer terms for a quantity surveying business set the boundaries of the engagement in plain language. They should define the services, assumptions, fees, timing, client responsibilities, and limits on liability so both sides know what has and has not been agreed.

Define the exact scope of services, deliverables and exclusions.
State the assumptions you are relying on, including information supplied by the client or third parties.
Set clear fee terms, invoicing points, reimbursement rules and interest on overdue accounts.
Explain how variations, additional work and urgent instructions are approved.
Limit liability to a fair level and exclude indirect or consequential loss where appropriate.
Clarify ownership and permitted use of reports, estimates, schedules and other deliverables.
Deal with delays, suspension rights and termination rights.
Make sure statements about expertise, timing and results do not overpromise under the Fair Trading Act.

What Customer Terms for Quantity Surveying Firm Means For New Zealand Businesses

Customer terms for quantity surveying firm work are the contract rules that sit behind your proposal, fee letter, quote or engagement letter. In practice, they decide what you must deliver, what the client must provide, and who wears the cost if things do not go to plan.

For New Zealand businesses, this matters because quantity surveying advice is often used in high-value projects with multiple decision-makers. A cost estimate can feed into funding, procurement, design choices and programme decisions. If your terms are silent or unclear, a client may try to treat your role as much wider than you intended.

A well-drafted contract is especially important where your work depends on plans, consultants' information, market pricing, site access or assumptions that may change. Your terms should make it clear when your advice is based on preliminary information and when it may need revision.

Why standard quotes are not enough

A one-page quote usually covers price and little else. That leaves unanswered questions about timing, reliance, use of your report, dispute handling, and whether you are responsible for matters outside your control.

This is where founders often get caught. They send a fee proposal, start work, and only talk about terms if there is a problem later. By then, it is harder to prove what was agreed.

What these terms usually need to cover

For a quantity surveying firm, customer terms usually need to do more than a generic consultancy template. The wording should reflect the actual services being provided, such as:

preliminary cost estimates
cost planning
tender analysis
procurement support
progress payment assessments
variation assessments
final account reviews
insurance reinstatement cost assessments
feasibility and budget advice

Each service has different reliance risks. A progress claim review may require strict wording about what has and has not been inspected. A feasibility estimate may need stronger assumptions language because design information is incomplete. A funder-facing report may need extra controls around who can rely on it.

How New Zealand law affects these terms

New Zealand contract law generally gives businesses room to agree their own commercial terms, but several legal frameworks still matter. Your customer terms need to work alongside the Fair Trading Act 1986, the Contract and Commercial Law Act 2017, the Consumer Guarantees Act 1993 where it applies, and the Privacy Act 2020 if you collect personal information.

For many quantity surveying engagements, the client will be another business. Even then, marketing statements and pre-contract representations still matter. If your proposal says you will “guarantee project costs” or implies a level of certainty that is unrealistic, that wording can create risk under the Fair Trading Act as well as ordinary contract principles.

The Consumer Guarantees Act is less likely to apply to purely business-to-business services where the parties are in trade and the contract validly records that the Act is contracted out of, where permitted. That point needs careful contract drafting. A generic clause copied from another industry may not be enough or may be used in the wrong setting.

Customer terms and client-supplied agreements

Many quantity surveying firms do not always use their own paper. A developer, builder, lender or project manager may send its own consultancy agreement and ask you to sign before you start.

That does not mean the document is standard or low risk. Client contracts often expand the scope through broad descriptions like “all services necessary for the project”, impose hard fitness-for-purpose obligations, or make you liable for delay and downstream losses that are not reasonable for your role.

Before you sign a contract drafted by the client, compare it against how your firm actually works. If the project team expects a practical cost consultancy role but the contract reads like a guarantee of budget accuracy, the mismatch can become expensive later.

Legal Issues To Check Before You Sign

The main legal issue is whether the written terms match the real job you are taking on. Before you sign, make sure the document describes a quantity surveyor's advisory role, not an open-ended promise to protect the client from every cost overrun.

1. Scope and exclusions

Your scope should say exactly what you will do, what deliverables you will provide, and what is excluded. If the engagement is limited to a cost estimate based on concept drawings, say so.

It also helps to state what you are not doing. Exclusions may include:

design services
structural or engineering review
geotechnical assessment
legal compliance certification
project management
clerk of works or site supervision
independent verification of third-party data unless expressly included

Without exclusions, a client may argue those tasks were implied because they were useful to the project.

2. Assumptions and reliance on information

A quantity surveyor often depends on plans, specifications, pricing data, programme information and instructions provided by others. Your terms should say that your advice is prepared in reliance on that information and may need revision if it changes.

If you are not verifying dimensions, latent conditions, builder solvency, or consultant inputs, say that clearly. This can be one of the most important clauses in the contract.

3. Fees, variations and payment timing

Fee disputes usually come from unclear scope creep. The contract should state whether the fee is fixed, capped, hourly, staged, or based on a schedule of rates. It should also explain when invoices are issued and when payment is due.

If extra work can be instructed verbally, say how it will be confirmed. A practical clause may allow you to act on urgent instructions but require prompt written confirmation, with the work charged as a variation.

It is also sensible to cover:

disbursements and third-party costs
travel time and site visit charges
re-pricing due to design changes or delay
interest or recovery costs for overdue invoices
the right to suspend work for non-payment

4. Timeframes and delays

Project timetables can move quickly, but your terms should avoid creating an absolute guarantee that deliverables will be issued by a fixed date regardless of what happens around you. A better approach is to say timeframes depend on receiving necessary information, access and instructions on time.

If the client delays or changes the brief, your contract should let you revise the programme and fees. Otherwise, your team may be pressured to absorb costs caused by someone else's delay.

5. Liability caps and excluded loss

Liability clauses are central for professional services. A sensible contract often limits your liability to a stated amount, frequently linked to the fee, insurance level, or another negotiated cap. It should also exclude liability for indirect or consequential loss, such as lost profits or financing impacts, where appropriate.

The right cap depends on the project, the service, your insurance arrangements and the bargaining power of the parties. The point is not to avoid all responsibility. The point is to keep liability proportionate to the role you are performing and the fee you are charging.

Watch for clauses that make you liable for:

all project losses however caused
acts or omissions of other consultants or contractors
fitness for purpose outcomes
uncapped indemnities
liability continuing even where the client contributed to the loss

6. Professional judgement versus guarantees

Your reports and estimates should be framed as professional opinions based on stated assumptions, not promises of a guaranteed project cost. Construction pricing is affected by market conditions, design development, procurement method and many other variables.

Terms that overstate certainty can create both contract risk and misleading conduct risk. This is particularly relevant where marketing material, proposals and engagement terms use different language.

7. Intellectual property and permitted use

Your deliverables may include reports, cost plans, spreadsheets, schedules and commentary. The contract should say who owns those materials and how the client may use them.

Often, the commercial outcome is that the firm keeps ownership in its underlying materials and grants the client a licence to use the deliverables for the agreed project and purpose once fees are paid. If a report could be circulated to lenders, purchasers or contractors, the terms should control that use and restrict third-party reliance unless expressly agreed.

8. Privacy and confidential information

Privacy is not always the first issue people think about in quantity surveying engagements, but it can still matter. If you collect names, contact details, financial information connected to sole traders, guarantors or individual property owners, you need to handle that personal information in line with the Privacy Act 2020.

Your terms can also include confidentiality obligations around project budgets, tender pricing and commercially sensitive material, and a short privacy notice where relevant.

9. Termination and suspension rights

You need a clear path out if the client does not pay, does not cooperate, asks you to act improperly, or the project pauses. The contract should explain when either side may terminate and what happens to fees and work in progress.

A useful clause often deals with:

payment for work performed up to termination
reasonable demobilisation costs
the right to retain deliverables until invoices are paid, where legally appropriate
return or destruction of confidential information
ongoing effect of liability, confidentiality and intellectual property clauses

10. Dispute process and governing law

If something goes wrong, a basic dispute clause can save time. It may require senior representatives to meet first, followed by mediation before court proceedings, unless urgent relief is needed.

For New Zealand-based work, governing law and jurisdiction should usually be New Zealand unless there is a good commercial reason otherwise.

Common Mistakes With Customer Terms for Quantity Surveying Firm

The most common mistake is using customer terms that look professional but do not reflect the real pressure points in quantity surveying work. A generic services template can leave major gaps around assumptions, reliance and liability.

Using old templates without project-specific updates

Founders often reuse a precedent prepared for a different service line or a much smaller job. The fee changes, but the legal mechanics stay the same.

This creates problems where the deliverables, client type or reliance profile is different. A bank-facing report, for example, may need tighter wording than a routine internal budgeting exercise for a repeat developer client.

Leaving the scope too broad

Broad scope wording may feel client-friendly at the start, but it often causes disputes later. Phrases like “all quantity surveying services required” or “full support for the project” do not help either side when the project changes.

Specific wording is safer. It gives the client clarity and gives your team a workable reference point when new requests appear midstream.

Failing to record assumptions

If your estimate relies on concept drawings, indicative procurement assumptions, provisional quantities or market benchmarks, those points should be documented. A client may remember the headline number, not the conditions attached to it.

Before you rely on a verbal promise that “the design will stay more or less the same”, put the assumption into the contract or report.

Accepting uncapped or one-sided liability clauses

Some client-drafted agreements place nearly all project risk on the consultant. That can include uncapped indemnities, broad warranties, and liability for losses far beyond the value of the engagement.

If you accept those terms without negotiation, your insurance may not respond in the way you expect. The contract and the policy should be checked together.

Not matching proposals, reports and formal terms

Another common problem is inconsistency between documents. The proposal may describe the service narrowly, the standard terms may be broader, and the final report may contain caveats that do not align with either.

When a dispute arises, clients often point to the wording that helps them most. Consistency across the proposal, engagement terms and deliverables reduces that risk.

Starting work before the paperwork is settled

Commercial pressure often leads firms to begin with an email or phone instruction, with the contract to follow. That can work if the terms are already agreed and clearly incorporated. It is much riskier if key clauses are still under discussion.

Before you spend money on setup, site visits or consultant coordination, make sure there is a clear written record of:

who the client is
what services are included
what fee basis applies
what assumptions and exclusions apply
which terms govern the engagement

Forgetting third-party reliance issues

Quantity surveying documents are often shared beyond the original client. Lenders, investors, insurers, contractors and purchasers may all want to see the report.

If your terms do not control reliance, someone who was never part of the fee negotiation may still try to use your advice as if it were prepared for them. This is a major area to sort out before you sign.

FAQs

Do quantity surveying firms need written customer terms for every job?

In most cases, yes. Small repeat jobs may use a shorter engagement letter, but there should still be written terms covering scope, fees, assumptions and liability. Relying on emails alone usually leaves too much room for argument.

Can a quantity surveying firm limit its liability in New Zealand?

Often, yes, if the clause is drafted properly and fits the commercial context. The cap needs to be reasonable, clear and consistent with the rest of the contract and your insurance position.

Only if your terms allow that, or you separately consent. If third-party use is likely, the contract should say who may rely on the report and for what purpose.

What if the client changes the brief after work starts?

Your terms should treat that as a variation or additional service. The contract should let you adjust fees, timing and assumptions when the scope changes.

Do customer terms need to mention the Consumer Guarantees Act?

If you are dealing with clients in trade and want to contract out where permitted, that point should usually be addressed expressly. The wording needs to suit the particular engagement and client relationship.
