When you’re buying or selling a business in New Zealand, “goodwill” is one of those terms that gets thrown around a lot - and it can have a real impact on what the business is worth, what you’re actually paying for, and what happens if things don’t go to plan after settlement.
Goodwill can also be the most “invisible” part of a deal. You can point to equipment, stock, a lease, and a customer list. But goodwill? It’s often the difference between a business that looks good on paper and a business that reliably makes money in the real world.
In this guide, we’ll break down goodwill in business sales in plain English, with a practical focus on what it means for small business owners - and how to handle it properly in your sale documents, negotiations, and due diligence.
What Is Goodwill In A Business Sale?
Goodwill is the value of a business that sits beyond its identifiable assets and liabilities.
In a practical sense, goodwill is usually the value of things like:
- your reputation in the market
- your customer relationships and repeat trade
- your brand recognition (even if it’s not formally trade marked)
- your location and foot traffic (where relevant)
- your systems and know-how that make the business run efficiently
- your online presence (website, reviews, SEO rankings, social media following)
- your supplier relationships and pricing power
Put simply: goodwill is why a buyer is willing to pay more than the “hard assets” are worth.
Example: If a café’s equipment, stock, and fitout are worth $80,000, but the buyer pays $160,000 for the business, the extra $80,000 is often (not always, but often) goodwill - because the café has an established customer base, strong local reputation, and predictable turnover.
Goodwill matters because, in many small business transactions, it’s the biggest part of the price.
Why Does Goodwill Matter In Business Sales?
If goodwill is misunderstood (or not properly documented), it can create disputes and disappointment quickly - especially in the first 3–12 months after settlement when the buyer is trying to “inherit” the business’s momentum.
Here’s why goodwill in business sales is so important.
It Influences The Purchase Price And Negotiation
Goodwill is often where negotiations get most emotional. A seller may feel goodwill reflects years of effort and reputation. A buyer may feel goodwill is “riskier” than physical assets because it can disappear if customers don’t stick around.
Getting clear on what’s driving the goodwill (and what protections exist for it) makes price discussions far more grounded.
It Affects What The Buyer Is Actually Buying
In a business sale, you’re not just transferring things - you’re transferring an operating “engine” that produces revenue.
If the documents only deal with assets (like stock and equipment) but don’t properly address goodwill-related issues (like restraints, handover, or key relationships), the buyer might not actually receive what they believed they were buying.
It’s Closely Tied To Restraints Of Trade And Transition Support
Goodwill often depends on the seller stepping away in a way that doesn’t undermine the buyer. That’s why restraints of trade and handover obligations are common in business sale agreements.
If you’re selling, you’ll want the restraint to be reasonable (so it’s enforceable and doesn’t overreach). If you’re buying, you’ll want the restraint to genuinely protect the goodwill you’re paying for.
This is where having a properly drafted Business Sale Agreement becomes more than just a “formality” - it’s one of the main ways goodwill is protected in real terms.
Types Of Goodwill You Might See In NZ Business Sales
Goodwill isn’t always one single thing. In practice, it can come from different sources - and that source affects how “stable” the goodwill is, and what should be documented.
Personal Goodwill (Owner-Dependent Goodwill)
This is goodwill that exists mainly because of the current owner’s personal reputation, skills, relationships, or presence.
Common examples include:
- a trades business where most work comes from the owner’s relationships
- a professional services practice where clients are loyal to an individual
- a boutique retailer where the owner is “the face” of the brand
Why it matters: personal goodwill can drop sharply after a sale unless there’s a strong transition plan (and sometimes ongoing involvement for a period).
Enterprise Goodwill (Business-Dependent Goodwill)
This is goodwill that attaches more to the business itself than the owner - for example, because it has strong systems, staff capability, a recognised brand, or a proven location.
Common examples include:
- a hospitality venue with repeat local customers and strong Google reviews
- a manufacturing business with stable contracts and repeat orders
- an online business with strong organic traffic and repeat customers
Why it matters: enterprise goodwill is usually more “transferable” - and therefore easier to justify in price negotiations.
Location Goodwill
Some businesses are valuable mainly because of where they operate (think retail, hospitality, service stations, gyms, etc.).
In those cases, goodwill can depend heavily on keeping the premises. If the lease can’t be assigned or renewed, the goodwill might not survive.
That’s why buyers often treat the lease as a key condition of the deal, and why an Deed of Assignment of Lease is commonly part of settlement where the premises are being transferred.
How Is Goodwill Calculated In A Business Sale?
There isn’t one universal formula for goodwill. In many deals, goodwill is effectively the “gap” between the total price and the value of identifiable assets (minus liabilities), but the reasoning behind the number should still be clear.
In NZ, goodwill is commonly assessed using a mix of:
- earnings multiples (e.g. a multiple of EBITDA, owner’s discretionary earnings, or net profit)
- maintainable earnings (how stable and repeatable the income is)
- customer concentration risk (whether revenue depends on one or two key customers)
- staff and systems (how dependent the business is on the owner personally)
- market conditions (competition, trends, regulatory changes)
- intellectual property and brand strength (name, logo, domain names, social accounts)
It’s also common for parties to agree on a price commercially (based on what the market will pay), then structure the agreement and allocations to match.
Important: if you’re allocating value between goodwill, plant/equipment, and stock, it’s worth getting both legal advice and accounting advice. The allocation can have tax and reporting consequences, and it can also affect what happens if there’s a dispute later about what was included in the sale. This article is general information only and isn’t tax advice - if you need tax guidance, it’s best to speak with an accountant.
How Do You Protect Goodwill In A Business Sale Agreement?
Goodwill can be fragile. From a legal perspective, protecting goodwill is about making sure the buyer has a fair shot at stepping into the seller’s position - without interference - and that the buyer receives what they were promised.
Here are some key clauses and practical steps that often protect goodwill in business sales.
1. Clearly Describe What’s Being Sold
Your sale documents should clearly list what’s included in the deal, such as:
- business name / trading name
- customer databases and supplier lists (to the extent they can be lawfully provided and used, including from a privacy/confidentiality and consent perspective)
- website domain and social media accounts
- phone numbers and email addresses used for the business
- branding assets and marketing materials
- key contracts (supplier contracts, customer contracts) that are being assigned or novated (where permitted and with any required consents)
Goodwill is often described broadly in the agreement, but the details matter. If a buyer thinks they’re receiving the Instagram page and the seller thinks it’s “personal”, that’s a goodwill dispute waiting to happen.
2. Include A Reasonable Restraint Of Trade
A restraint of trade is one of the most common ways to protect goodwill. It usually restricts the seller from:
- starting a competing business within a certain area
- working for a competitor
- soliciting customers, suppliers, or staff
Restraints need to be carefully drafted to be enforceable. If they’re too broad, they may be difficult to rely on when it counts.
If you’re buying, you want the restraint to match the goodwill you’re paying for. If you’re selling, you want to make sure it’s reasonable and doesn’t unnecessarily limit your future work options.
3. Plan The Handover (And Put It In Writing)
Goodwill doesn’t transfer automatically just because the money changes hands. A proper handover period often makes a big difference to whether customers stick around.
A business sale agreement might include things like:
- a handover period (e.g. 2–8 weeks)
- training for the buyer or key staff
- introductions to major customers and suppliers
- support in transferring key accounts (utilities, online platforms, payment processors)
It’s worth being specific. “Reasonable assistance” can mean very different things to a buyer and seller once settlement is done.
4. Deal With Employees Properly
In many small businesses, goodwill is tied to the team. If key staff leave right after settlement, customers may follow them - especially in service-based businesses.
When you’re selling, you’ll want to be careful about how you communicate the sale and how the transition is handled. When you’re buying, you should understand which employees are staying, what their terms are, and whether there are any key person risks.
This is also where having up-to-date Employment Contract documentation matters, particularly for senior or client-facing employees.
5. Make Sure Marketing And Representations Are Accurate
Goodwill often shows up in how a business is marketed for sale - “highly loyal customer base”, “recurring contracts”, “strong reputation”, “exclusive supplier arrangements”, and so on.
In NZ, statements made in negotiations or advertising can create legal risk if they’re misleading. The Fair Trading Act 1986 is particularly important here, because it prohibits misleading or deceptive conduct in trade.
That doesn’t mean you can’t present your business in the best light - you can. It just means the claims should be accurate, supportable, and properly handled in the sale process.
Common Goodwill Disputes (And How To Avoid Them)
Most goodwill disputes don’t start with anyone trying to be difficult. They usually happen because expectations weren’t aligned - or because the agreement didn’t deal with a key risk.
Here are a few common issues we see around goodwill in business sales.
The Seller Starts Competing Too Soon
If the seller opens a similar business nearby, contacts former customers, or quietly takes contracts back, the buyer may argue the goodwill they paid for has been damaged.
A well-drafted restraint, plus clear non-solicitation obligations, can help prevent this.
Key Customers Or Suppliers Don’t Transfer
Sometimes buyers assume customer contracts will “just continue” post-sale - but contracts may need assignment, consent, or novation (and in some cases, they may not be transferable at all).
Where your business relies on a few key contracts, it’s worth addressing them specifically and building conditions into the deal (for example, settlement is conditional on key customer consent).
The Business Was Overstated During The Sale Process
If the buyer later discovers the revenue was inflated, key costs weren’t disclosed, or “repeat customers” were actually one-off jobs, goodwill becomes the battleground.
This is where due diligence and proper warranties can be crucial. It’s also why many sellers benefit from preparing properly before going to market, including getting their paperwork and numbers in order.
The Buyer Changes The Business And Goodwill Drops
Sometimes goodwill drops because the buyer changes the branding, raises prices, changes staff, or alters products/services - and customers don’t like it.
This is a tricky one, because the seller can’t guarantee future performance. But clear handover support, accurate records, and realistic expectations help reduce the risk of disputes on both sides.
If you’re not sure how to structure the process, a Legal Due Diligence review can help identify where goodwill is coming from (and where it’s most vulnerable) before you commit.
Key Takeaways
- Goodwill in business sales is generally the value of the business beyond its identifiable assets - it’s often tied to reputation, customers, systems, and the ability to generate future earnings.
- Goodwill is usually a major driver of the purchase price, but it can also be one of the riskiest parts of a deal because it’s harder to “see” and can be lost quickly after settlement.
- In practice, goodwill may be personal (owner-dependent), enterprise-based (system and brand-driven), or linked to location - and understanding the type of goodwill helps you negotiate and document the deal properly.
- Protecting goodwill often comes down to the sale agreement terms, including a clear description of what’s being transferred, a reasonable restraint of trade, and practical handover obligations.
- Goodwill disputes commonly arise when the seller competes, key relationships don’t transfer (or can’t be transferred without consent), or the business was misrepresented - and these risks can usually be reduced with solid due diligence and carefully drafted documents.
- If your business premises are critical to goodwill, make sure the lease transfer is handled properly - the deal may rely on the lease being assigned and documented correctly.
