How To Value Goodwill When Selling A Business In NZ

If you’re selling your business, you’ll quickly realise the sale price isn’t just about stock on hand, equipment, or the lease. A big part of what you’re really selling is the “good stuff you can’t touch” - your reputation, customer loyalty, systems, and the future income a buyer believes they can earn.

That’s goodwill, and getting your goodwill valuation right can have a major impact on your final deal (and on how smooth your negotiations are).

In this guide, we’ll break down what goodwill is, how it’s commonly valued in New Zealand, what documents can help support the number, and the legal issues that can make or break a goodwill-heavy sale. (Just note: valuing goodwill is primarily a commercial/accounting exercise - your lawyer can help make sure the value you negotiate is properly documented and protected, but you’ll often want input from your accountant or a valuer on the actual numbers.)

What Is Goodwill In A Business Sale (And Why Does It Matter)?

Goodwill is the value of your business above and beyond its identifiable assets and liabilities.

In plain terms, if your business could be recreated tomorrow by buying the same equipment and leasing a similar premises, but it still wouldn’t earn the same profits without you and your brand… that difference is usually goodwill.

Goodwill can include things like:

• Brand reputation (how well-known and trusted your business is)
• Customer relationships and repeat business
• Supplier relationships and favourable pricing/terms
• Location advantage (for some businesses, the site itself creates value)
• Systems and processes that make the business efficient and scalable
• Trained staff and a stable team (where key people are likely to stay post-sale)
• Online presence (website authority, SEO rankings, email lists, social media audiences)
• Contracts that lock in future revenue (where they can legally transfer)

Goodwill matters because most buyers aren’t paying for what your business has today - they’re paying for what it can reliably produce tomorrow. A strong goodwill valuation helps you:

• justify your asking price with evidence (not just “it’s a great business”)
• reduce the risk of last-minute price reductions during due diligence
• structure the sale correctly (asset sale vs share sale can affect what’s being sold)
• reduce disputes after settlement about “what was included” in the price

When it comes time to document the transaction, your Business Sale Agreement should clearly deal with goodwill - including what’s included (and not included), how it’s described in the sale, and what protections exist if the goodwill drops because of something the seller does after the sale.

What Drives Goodwill Value In New Zealand?

There isn’t one universal “goodwill formula” that works for every business. A goodwill valuation depends heavily on what makes your business defensible, repeatable, and profitable.

Here are some of the biggest goodwill drivers buyers in NZ tend to focus on.

1. Consistent, Defensible Earnings

Goodwill is usually tied to profits. If your financials show stable earnings over time (or clear growth), goodwill tends to increase because a buyer can more confidently forecast future returns.

Buyers will commonly look at:

• 3+ years of financial statements and tax returns
• normalised earnings (more on that below)
• concentration risk (e.g. “one client makes up 60% of revenue”)

2. The Business Being Transferable (Not “Owner-Dependent”)

One of the quickest ways goodwill gets discounted is if the buyer believes the business’s success depends on you personally.

For example, if you’re the only person who knows the key processes, manages all relationships, or holds all supplier contacts, a buyer may treat goodwill as fragile.

To strengthen goodwill, buyers like to see:

• documented systems and processes
• staff capability to run day-to-day operations
• contracts and relationships held in the business name (not personally)

3. Your Contracts (And Whether They Can Be Assigned)

Service contracts, supply agreements, and recurring revenue arrangements can significantly support goodwill - but only if the buyer can actually take them over.

In an asset sale, contracts often need to be assigned or replaced. If the contract terms require consent (or prohibit assignment), the buyer may discount goodwill until they’re confident clients will stay.

This is one reason sellers often do a legal tidy-up before going to market: it can make the goodwill easier for a buyer to get comfortable with.

4. Your Lease Or Premises Arrangements

If your location is key to your success (think hospitality, retail, medical, fitness), then goodwill can rise or fall depending on the lease terms and whether the lease can be transferred or renewed on workable terms.

It’s common for buyers to request a lease review or negotiate an assignment/extension. If you’re dealing with landlord consent and lease transfer terms, it’s worth getting a Commercial Lease Review early, so you’re not caught out during negotiations.

5. Legal Compliance And Risk Profile

Goodwill isn’t just about revenue - it’s also about risk.

If a buyer finds red flags (employment issues, poor record keeping, misleading advertising, privacy gaps, disputes), goodwill can be marked down because the buyer is pricing in the cost and uncertainty of fixing problems after settlement.

As a starting point, sellers should ensure they’re compliant with:

• Fair Trading Act 1986 (advertising and representations about the business must not be misleading)
• Consumer Guarantees Act 1993 (if you sell to consumers and certain guarantees apply)
• Privacy Act 2020 (if you collect customer data, mailing lists, bookings, CCTV, etc.)

If your business collects personal information (even something as basic as customer emails), having a properly drafted Privacy Policy can help show the buyer you’ve taken compliance seriously.

Common Goodwill Valuation Methods (In Plain English)

Goodwill valuation can feel mysterious because it’s not tied to a single tangible asset. In practice, most methods are ways of estimating how much extra income the buyer expects to earn from the goodwill - and what they’re willing to pay today for that future benefit.

These approaches are often discussed with accountants and valuers, and used commercially as a basis for negotiation. Your lawyer’s role is usually to help ensure the price and goodwill-related assumptions are clearly captured in the contract (and that you’re not accidentally making promises you can’t support).

Here are the most common approaches you’ll come across in New Zealand business sales.

1. Capitalisation Of Earnings (A Multiple Of Maintainable Earnings)

This is one of the most common approaches in SME sales.

In simple terms, the buyer looks at your “maintainable earnings” (often EBITDA or seller’s discretionary earnings) and applies a multiple. The multiple reflects risk and growth prospects.

For example (simplified):

• Maintainable earnings: $200,000/year
• Multiple: 3x
• Implied business value: $600,000

Then the buyer separates out the value of identifiable assets (stock, equipment, vehicles) and what remains is effectively goodwill.

Key tip: be prepared to explain and evidence your earnings. A “normalisation” exercise is common - removing one-off costs, adjusting owner wages to market rates, and excluding personal expenses. If this isn’t handled carefully (and consistently across documents), it can lead to confusion, mistrust in the numbers, or negotiations stalling.

2. Excess Earnings Method

This method is a bit more technical but still fairly common in valuation discussions.

Broadly, it works like this:

• Value the tangible assets and apply a reasonable return you’d expect from them
• Compare that to the business’s actual earnings
• The “excess” earnings are attributed to goodwill, then capitalised

This approach can be useful where the business has significant assets (e.g. plant/equipment), but still earns above what those assets alone would justify.

3. Market Comparable Sales

This method looks at sales of similar businesses and applies market benchmarks (like “X times earnings” or “Y% of revenue”).

It’s helpful, but it has limitations - because “similar business” doesn’t always mean “similar risk”. A café with a rock-solid lease and strong repeat trade is not the same as a café with a lease about to expire and revenue tied to one head chef.

4. Discounted Cash Flow (DCF)

DCF forecasts future cash flows and discounts them back to today’s value using a discount rate (reflecting risk and the time value of money).

DCF is more common in larger transactions or where forecasting is reliable. For many small businesses, it can be harder to use because forecasts can be more uncertain - but it can still be useful where the business has contracted future revenue.

So Which Goodwill Valuation Method Is “Best”?

There’s no single best method. In most SME deals, the commercial reality is that goodwill valuation is a negotiation, and the valuation method is the “story” that supports the number.

That’s why it’s important to prepare your financial and legal foundations early - you want your goodwill position to be defensible when a buyer (and their accountant/lawyer) starts testing your assumptions.

How Do You Prove Goodwill Value To A Buyer (And Avoid Price Chipping)?

Goodwill is only valuable if a buyer believes it will survive the handover.

While you can’t “prove” goodwill in the same way you prove ownership of a physical asset, you can support your asking price with evidence that the business is stable, transferable, and low-risk - and reduce the chances of “price chipping” (where the buyer tries to re-trade the price after finding issues).

Prepare A Due Diligence Pack Early

Buyers will usually ask for detailed information before they commit. If you’re organised, you can keep negotiations on track and reduce “price chipping”.

Your pack may include:

• financial statements and management accounts
• customer metrics (repeat rates, booking volume, retention, churn)
• supplier terms and key relationships
• key contracts (client agreements, supplier agreements, service terms)
• lease documents and landlord correspondence
• employee info (roles, pay rates, leave, tenure) - without oversharing sensitive personal information
• IP and brand assets (trade marks, domains, website admin access)

Many sellers find it helpful to run a legal tidy-up in advance so there are no surprises. This is also where a Legal Due Diligence process can help identify risks before a buyer does.

Get Your Customer-Facing Terms In Order

If you sell products or services, buyers often want to see:

• clear terms that reduce refund/dispute risk
• proper limitation of liability wording (where appropriate and enforceable)
• a process for complaints and returns

Depending on your business, this might mean tightening up your Business Terms or service agreements, especially if a large part of your goodwill comes from repeat customers and reputation.

Show That Your Team And Systems Will Survive The Sale

Where goodwill is tied to people and delivery quality, buyers will look at the stability of your team.

That doesn’t necessarily mean locking people in (that can be tricky), but it does mean:

• having properly documented roles and employment records
• clear performance expectations and policies
• reducing the risk of disputes during the transition

If you’re hiring or reviewing contracts before a sale, it can be worth checking your Employment Contract terms are fit for purpose, as employment issues can quickly erode perceived goodwill.

Goodwill Valuation And The Legal Structure Of Your Sale

When we talk about goodwill valuation, it’s not just about price - it’s also about what the buyer is legally buying.

In NZ, business sales are commonly structured as either:

• Asset sale (buyer purchases business assets, which can include goodwill)
• Share sale (buyer purchases shares in the company that owns the business)

The structure affects:

• what transfers automatically and what needs assignment/consent
• what liabilities the buyer may inherit
• how warranties and indemnities are negotiated
• how the goodwill is described in the sale documents

Asset Sale: Goodwill Is Often A Key Line Item

In an asset sale, goodwill is often expressly listed as an asset being sold. This can be helpful because it forces clarity: you specify what is included (brand, customer list, phone number, website, social accounts, etc.) and what the seller must do to protect goodwill post-sale.

Share Sale: Goodwill Is “Inside” The Company

In a share sale, the buyer acquires the company (and everything inside it). Goodwill is still part of the valuation, but the buyer will usually be more focused on company-wide risk - including historical compliance, contracts, and any unresolved disputes.

Either way, if you have co-owners or shareholders, it’s worth checking your governance documents early. A clear Shareholders Agreement can prevent internal conflict that delays the sale or undermines value (especially where one owner wants to sell and another doesn’t).

Restraint Of Trade: Protecting The Goodwill The Buyer Pays For

One of the most common buyer concerns is: “What stops the seller from opening a competing business next door and taking the customers back?”

That’s where restraint of trade clauses come in. They’re often included in business sale agreements to protect the goodwill the buyer is paying for.

In NZ, restraints need to be reasonable to be enforceable - and what’s “reasonable” depends on things like:

• the type of business
• the area the business operates in
• how long the restraint lasts
• the seller’s role and influence over customers

This is one of those areas where DIY templates can backfire. If the restraint is too broad, it may not be enforceable. If it’s too narrow, the buyer may argue the goodwill isn’t protected and push the price down.

Key Takeaways

• Goodwill valuation is about the value of your business beyond its tangible assets - often tied to reputation, customer loyalty, systems, and future earnings.
• Goodwill generally increases when earnings are consistent, risks are low, and the business can run without being overly dependent on you as the owner.
• Common goodwill valuation methods include capitalisation of earnings (multiples), excess earnings, market comparables, and discounted cash flow - and the “best” approach depends on your business and the buyer (and is often worked through with an accountant or valuer).
• You can strengthen and defend goodwill by preparing early: organise financials, tidy contracts, confirm lease transfer options, and fix compliance gaps before the buyer’s due diligence begins.
• The legal structure of the sale (asset sale vs share sale) affects what is being transferred, what consents are required, and how goodwill is protected in the transaction documents.
• Restraint of trade clauses are often critical to preserving goodwill after settlement, but they must be drafted carefully to be enforceable and commercially workable.
