What Is Goodwill In Business?

If you’re buying a business, selling one, or raising investment, you’ll probably hear the word goodwill pretty quickly.

And it can feel a bit strange at first - because goodwill isn’t a stock item you can count, and it’s not a piece of equipment you can touch. But it can be one of the biggest drivers of business value.

In this guide, we’ll walk through what goodwill is in a practical, New Zealand-focused way, including how goodwill is valued, when it matters most, and the legal issues that can make a real difference to it.

What Is Goodwill In Business (In Plain English)?

Goodwill is the extra value of a business above the value of its identifiable assets (like stock, equipment, vehicles, or cash).

So, when someone asks what is goodwill, a helpful way to think about it is:

• Goodwill is what you’re paying for when you’re paying “more than the parts”.

It’s the value of the business as an ongoing operation - including things like reputation, customer loyalty, systems, brand presence, supplier relationships, and the ability to keep generating profits.

A Simple Example Of Goodwill

Imagine a café is being sold for $250,000. The buyer and seller agree the identifiable assets are worth:

• Equipment and fit-out: $80,000
• Stock: $10,000
• Cash in till and minor items: $5,000

That’s $95,000 in identifiable assets.

If the purchase price is $250,000, then goodwill is the difference (in this simplified example):

• $250,000 - $95,000 = $155,000 goodwill

What is the buyer paying $155,000 for? Usually things like the café’s name in the local area, repeat customers, its location advantage, recipes, social media traction, and the systems that make it run smoothly.

Is Goodwill Always “Real”?

Goodwill can be very real - but it can also be fragile.

For example, if customers only come because a particular owner is there every day, and that owner is leaving after settlement, the goodwill might drop quickly unless you plan for a proper transition.

This is why goodwill isn’t just an accounting concept. It’s also a legal and commercial risk-management issue.

What Creates Goodwill In A Business?

Goodwill usually comes from the business’s ability to keep earning money into the future. In other words, it’s strongly linked to future maintainable earnings and the “stickiness” of your customers and revenue streams.

Common drivers of goodwill include:

• Brand reputation (the business is trusted and well-known in its market)
• Repeat customers (regulars, subscriptions, membership bases, long-term client relationships)
• Location advantage (foot traffic, visibility, convenience)
• Systems and processes (how smoothly the business runs without constant owner intervention)
• Staff knowledge and capability (a strong team can keep services consistent)
• Supplier relationships (pricing, exclusivity, reliability)
• Online presence (SEO rankings, audience, customer reviews)
• Contracts and recurring revenue (signed clients, retainer agreements, predictable forward orders)

If you’re a startup or scaling SME, this list is useful because it shows you what actually builds value beyond your physical assets.

Personal Goodwill vs Business Goodwill

One of the biggest “goodwill traps” we see is where goodwill is mostly tied to the founder personally (sometimes called personal goodwill).

For example:

• a consultant whose clients only want them, not the business
• a trade business where all relationships sit with the owner’s phone number
• a health or professional services business where the “brand” is essentially one person

That doesn’t mean the business can’t be sold - but it does mean the buyer will likely want protections, like handover obligations, restraint provisions, and clear assignment of client contracts where possible.

When Does Goodwill Matter Most For New Zealand Business Owners?

Goodwill shows up in a few key moments in a business lifecycle. If you’re heading into one of these moments, it’s worth getting clear on what you’re selling (or buying), and how it’s protected.

1. Selling Your Business

If you’re selling your business, goodwill is often the biggest component of the purchase price - especially if your business doesn’t have expensive machinery or significant inventory.

This is where the Business Sale Agreement becomes critical, because it usually sets out:

• what goodwill is included in the sale (and what’s excluded)
• what the seller must do to help transfer goodwill (handover, introductions, training)
• restraints (so you don’t immediately compete and undermine what you sold)
• how customer lists, phone numbers, social media accounts, websites, and branding are handled

2. Buying A Business (Asset Sale vs Share Sale)

If you’re buying a business, goodwill is one of the main things you’re paying for - so you’ll want confidence you can actually “take it over” after settlement.

The structure of the deal matters here. For example, in an asset sale, you might be buying selected assets and goodwill, whereas in a share sale you’re buying the company (including its contracts, liabilities, and reputation).

Either way, getting the key deal terms right is important, and many buyers start with legal due diligence so you can confirm what you’re buying is what you think it is (and that there aren’t hidden legal issues that could damage goodwill later).

3. Bringing In Investors Or Co-Founders

When you bring in a co-founder or investor, goodwill can affect valuation and how shares are allocated. If your business has meaningful traction - strong brand, customer loyalty, or recurring revenue - that’s often what justifies the valuation above your hard assets.

This is also the stage where it’s smart to formalise decision-making and exits so the business can keep running smoothly (and protect goodwill even if someone leaves). For many companies, that means putting a Shareholders Agreement in place early.

4. Accounting And Financial Reporting

Goodwill can also appear in your financial statements, especially after an acquisition. Typically, purchased goodwill may be recorded when you buy a business for more than the fair value of its identifiable net assets.

Accounting and tax treatment can get technical quickly, and it depends on your circumstances (including deal structure) - so it’s worth speaking to your accountant or tax adviser about how goodwill should be treated for reporting and tax purposes.

From a legal perspective, the important point is: you should make sure the contract matches what your financial model assumes you’re receiving (for example, access to customer databases, the website domain, and rights to use business branding).

How Is Goodwill Valued In New Zealand?

There isn’t one universal goodwill formula in New Zealand. In practice, goodwill is often a negotiated figure supported by financial performance and the perceived strength of the business.

That said, goodwill valuation commonly involves methods like:

Capitalisation Of Earnings (Or Profit Multiple)

This approach looks at the business’s maintainable earnings (often adjusted for one-off expenses and owner-specific costs) and applies a multiple.

For example, if adjusted net profit is $120,000 and the multiple is 3, the implied value might be $360,000 (before considering debt/cash and other adjustments).

The “multiple” depends heavily on:

• industry norms
• reliability of revenue
• customer concentration risk (one big client vs lots of smaller ones)
• how involved the owner is day-to-day
• growth potential
• how transferable the business is

Market Approach (Comparable Sales)

This uses sale prices of similar businesses as a reference point.

In smaller markets (or niche industries), it can be hard to find genuinely comparable sales, but brokers often rely on this approach informally.

Asset-Based Approach (Often For Lower Goodwill Businesses)

This values the business based primarily on its net assets (assets minus liabilities).

In many service businesses, this may underestimate value - because most value sits in goodwill, not in physical assets.

Why Legal Risk Impacts Goodwill Valuation

Two businesses might have the same profit - but very different goodwill value - depending on legal risk.

For example, goodwill may be discounted if:

• key customer contracts aren’t in writing (or aren’t assignable)
• IP ownership is unclear (like who owns the brand, content, software, or designs)
• there are employment disputes or compliance issues
• there’s a history of misleading advertising (Consumer Guarantees Act 1993 risk)

So even if goodwill looks strong “on paper”, it’s worth stress-testing whether it’s legally secure.

What Legal Issues Affect Goodwill When Buying Or Selling A Business?

This is where a lot of SMEs get caught out. You can have a profitable business - but if the legal transfer isn’t handled properly, the buyer may not receive the goodwill they paid for (and the seller may face disputes after settlement).

Restraint Of Trade (So The Seller Doesn’t Undermine The Sale)

If you sell a business and then immediately start competing nearby or poach customers, you can effectively damage the goodwill you sold.

That’s why many business sale deals include restraint clauses (limits on what the seller can do, for how long, and in what geographic area).

These clauses need to be drafted carefully. In New Zealand, restraints are generally only enforceable to the extent they’re reasonable in scope and necessary to protect a legitimate business interest - so they should be tailored to the deal and the goodwill being sold.

Assignment Of Key Contracts

If the goodwill is tied to contracts (like supplier agreements, customer retainers, leases, or software subscriptions), you need to confirm whether those contracts can be assigned to the buyer.

If they can’t be assigned automatically, you may need:

• counterparty consent
• new contracts signed on updated terms
• a structured transition period

This is especially important for leases - the premises can be a major part of goodwill for retail, hospitality, and many service businesses. If a lease transfer is needed, you may be looking at an assignment process and documents like a Deed of Assignment of Lease.

Brand And IP Ownership

A surprising number of small businesses don’t technically own all the key assets that create goodwill.

For example:

• a founder registered a domain name personally
• a contractor built the website but didn’t assign IP
• a logo was designed without clear IP terms
• a business name is used but trade mark protection hasn’t been considered

If the buyer can’t legally use the brand assets after settlement, they may not be getting the goodwill they expected.

Employment And Team Continuity

For many businesses, a strong team is a big part of goodwill. If key staff leave at settlement, service quality can drop and customers may follow them elsewhere.

From a legal perspective, you should also be clear on what happens to employees on sale. For example, some buyers want to ensure contracts, policies, and role structures are up to date so the transition is smoother.

It’s often a good time to review or update your Employment Contract templates (especially if the business is growing or changing hands).

Consumer And Advertising Compliance (Protecting Reputation)

Reputation is goodwill - and in New Zealand, reputation can be damaged fast if customers feel misled.

That’s why it’s important to comply with consumer protection laws such as:

• Consumer Guarantees Act 1993 (including misleading or deceptive conduct, false claims, and unfair practices)

If a business has a pattern of questionable advertising or unclear returns policies, that’s not just a legal risk - it can reduce goodwill and impact valuation in due diligence.

Data, Customer Lists, And Privacy

Customer lists and mailing lists can be a major goodwill asset, especially for ecommerce and subscription businesses.

But you need to handle personal information carefully and in line with the Privacy Act 2020 (and any applicable regional laws and industry rules).

As a general rule, you should know:

• what personal information is being transferred
• whether customers were told their data might be used or transferred as part of business operations
• how the buyer will store and use the data going forward

For many SMEs, having a clear Privacy Policy (and following it in practice) is part of protecting goodwill - because it builds trust and reduces complaint risk.

How Can You Protect (And Grow) Goodwill In Your SME Or Startup?

Whether you plan to sell in five years or you’re just trying to build something valuable, goodwill is something you can actively protect - not just hope for.

Document Your Key Relationships

If your revenue depends on a few major clients or suppliers, make sure the relationship isn’t just informal. Consider written agreements that clearly cover:

• scope of work and pricing
• payment terms
• termination rights
• confidentiality and IP ownership

This makes the business more stable and easier to transfer (which often increases goodwill value).

Make Your Business Less Founder-Dependent

If you’re the “glue” holding everything together, goodwill may be harder to transfer.

Practical ways to reduce this risk include:

• documented processes and training manuals
• a second-in-command who can run operations
• shared access to key systems (not everything locked behind your personal logins)
• centralised customer communications through business accounts

Keep Your House In Order Legally

When it’s time for a sale or investment round, the fastest way to lose goodwill value is to discover legal gaps late.

For companies, it can help to have strong governance basics in place early, including a Company Constitution where appropriate (particularly if you have multiple shareholders, plan to raise capital, or want clearer internal rules).

It’s also worth keeping your key contracts consistent and updated as your business evolves - what worked at $200k revenue may not work at $2m.

Don’t DIY The Sale Documents

It’s tempting to treat goodwill as a “handshake concept” - but in a dispute, what matters is what the documents say.

A properly drafted sale agreement can reduce the risk of arguments about:

• what exactly was included in the sale (and what wasn’t)
• whether the seller has properly helped with handover
• whether the buyer is entitled to price reductions or claims after settlement

This is one of those areas where getting tailored advice upfront can save you a lot of cost (and stress) later.

Key Takeaways

• Goodwill is the value of a business beyond its identifiable assets, often tied to reputation, customer loyalty, systems, and future earning potential.
• If you’re trying to understand what goodwill is, it often comes down to why a business can be worth more than its equipment, stock, and cash - goodwill reflects the business as an ongoing operation.
• Goodwill matters most when buying or selling a business, raising investment, or formalising co-founder arrangements, because it directly impacts valuation and deal risk.
• Goodwill can be fragile if it’s heavily founder-dependent or if key contracts, staff, or brand assets can’t be transferred cleanly.
• Legal issues like restraint clauses, contract assignment, lease transfers, and IP ownership can make a major difference to the goodwill a buyer is paying for.
• Compliance with laws like the Consumer Guarantees Act 1993 and the Privacy Act 2020 helps protect reputation - and reputation is a core part of goodwill.
• Strong legal foundations early (clear contracts, governance documents, and policies) can make your business more valuable and easier to sell later.
