Debt vs Equity: Choosing the Right Funding for Startups

Choosing between debt vs equity is one of the first big funding decisions many New Zealand founders face, and it often gets rushed. A common mistake is taking money from family, friends or angel investors before the terms are written down properly. Another is signing a loan that looks simple, but gives the lender security over key business assets or personal guarantees the founder did not expect. A third is giving away too much ownership too early, then finding future investment rounds much harder to negotiate.

The right answer depends on what stage your startup is at, how predictable your revenue is, how much control you want to keep, and what legal obligations you are willing to take on. Debt can help you avoid dilution, but it creates repayment pressure. Equity can bring breathing room and strategic support, but it changes ownership and decision-making. This guide explains the legal and practical differences, what to sort out before you sign, and how to set up a funding arrangement in New Zealand with fewer surprises later.

Legal Checklist

Your funding choice affects ownership, control, disclosure, governance and future fundraising, so the legal documents should match the commercial deal from day one.

• Confirm your business structure and cap table are up to date, including who owns shares, who has authority to sign, and whether the company constitution restricts new funding.
• Decide whether the money is debt, equity, or a hybrid instrument such as a convertible note or SAFE-style arrangement, and make sure the documents reflect that choice clearly.
• Record the commercial terms in writing, including amount, repayment or conversion terms, interest, valuation, investor rights, default events and exit treatment.
• Check whether shareholder approval, board approval, or constitution changes are required before issuing shares or granting security.
• Review any financial markets law issues, especially if you are raising from multiple investors or making offers beyond close personal or wholesale investor relationships.
• Protect existing intellectual property by confirming founders have assigned key IP to the company before new investors come in.
• Put confidentiality, privacy and information-sharing rules in place before disclosing customer data, financial forecasts or commercially sensitive material during due diligence.
• Check related contracts for restrictions, such as bank covenants, lease clauses, supplier terms or existing shareholder agreements that limit borrowing or new share issues.

How To Structure The Legal Documents Properly

The first legal step is to decide what kind of money you are actually taking, because debt and equity create very different rights and risks.

Debt funding means the business borrows money and agrees to repay it, usually with interest and on set terms. Equity funding means the investor buys ownership in the company, usually in exchange for shares, and their return depends on growth, dividends or an eventual exit.

Founders often focus on the headline number and ignore the legal mechanics. This is where problems start. A $200,000 loan can be far more restrictive than a $200,000 equity round if it comes with broad security rights, monthly reporting obligations and a personal guarantee. On the other hand, a small equity investment can become expensive if it gives away too much control or creates vague investor rights that block future decisions.

Choose The Right Business Structure Before You Raise

Most startups seeking outside funding use a limited liability company. That is usually the simplest structure for issuing shares, recording ownership and bringing in investors.

Before you spend money on company setup, make sure your company records are clean. Check:

• the company is correctly registered with the Companies Office
• the current shareholding is accurate
• director details are current
• founder loans or informal cash injections have been documented
• any company constitution is available and understood

If you have been operating informally, this cleanup matters. Investors and lenders will usually want certainty about who owns the business and whether the company has legal authority to issue shares or borrow funds.

What Debt Funding Usually Requires

Debt works best where the business has a realistic path to making repayments. In legal terms, you will usually need a loan agreement and, in some cases, security documents.

A proper loan agreement should deal with:

• the amount being advanced
• interest, if any
• repayment dates and whether early repayment is allowed
• what happens if the business misses a payment
• whether the lender gets security over business assets
• whether directors or founders are giving personal guarantees
• reporting obligations and lender consent rights

Security is a major issue. If the lender takes security over company assets, that can affect future borrowing, investor appetite and operational flexibility. Before you sign a contract, make sure you understand exactly what assets are covered and what default triggers enforcement.

What Equity Funding Usually Requires

Equity is usually more suitable where the startup needs time to grow and cannot support regular repayments. The legal work usually includes a term sheet, share subscription or investment agreement, board and shareholder approvals, and updates to company records.

You may also need a shareholders agreement, or amendments to an existing one, to cover matters such as:

• director appointment rights
• voting thresholds for major decisions
• pre-emptive rights on new share issues
• founder vesting or leaver provisions
• drag-along and tag-along rights
• information rights for investors
• restrictions on selling shares

This is where founders often get caught. They accept investment on friendly terms, then realise the documents give the investor a veto over future fundraising, hiring, budgets or an exit. The legal drafting needs to match the deal you actually intend.

Convertible Notes And Hybrid Options

Some early stage startups use convertible notes or similar instruments as a middle ground. These start as debt and may convert into shares later, often at a discount or subject to a valuation cap.

These instruments can be useful where a current valuation is hard to agree. But they are not legally simple just because they postpone the equity discussion. The drafting still needs to cover maturity, interest, conversion triggers, default, investor rights and what happens if no priced round occurs.

Hybrid funding can be sensible, but only if the company and investor both understand when repayment applies and when ownership changes.

Legal Requirements And Compliance Issues To Check

There is no single startup funding licence for founders in New Zealand, but financial offers, company records, marketing claims and investor communications still need careful handling.

Do You Need Registration, Licensing Or Approval?

No, there is no general licence just to choose debt vs equity funding for your startup. However, you may need to comply with company law processes, financial markets rules and disclosure obligations depending on who you raise from, how you structure the offer and whether the offer falls within an exemption.

The legal position changes quickly once you go beyond a small private raise. If you are offering shares, convertible notes or other financial products to a wider group, the Financial Markets Conduct Act 2013 may become relevant. That is especially important if you are not relying on a close business associate, wholesale investor or other available exclusion or exemption.

Be Careful How You Describe The Investment

Labels matter, but the substance matters more. Calling something a loan does not make it debt if the terms really look like an equity investment. Calling someone an adviser does not avoid investor rights if they are contributing capital for ownership.

Promotional statements also need care. The Fair Trading Act 1986 applies to business representations, including statements made to potential customers and, in some situations, to investors. Do not overstate traction, revenue, partnerships, approvals or intellectual property ownership. Overconfident pitch decks create legal risk if the documents and facts do not back them up.

Company Records And Share Issuance Rules

If you choose equity, the company must issue shares properly. That usually means checking the constitution, passing director resolutions, meeting any shareholder approval thresholds, updating the share register and making the right Companies Office filings.

Founders sometimes treat early investment casually and record it later. That can create messy disputes about price, ownership percentage and voting rights. Before you sign and before money lands in the company account, make sure the issue price, class of shares and attached rights are settled in writing.

Privacy And Due Diligence

Most funding discussions involve sharing financial data, product plans, team information and customer metrics. If any of that material includes personal information, the Privacy Act 2020 may affect how you collect, use and disclose it.

Before you hand over data rooms or spreadsheets, think about:

• whether customer or staff information can be anonymised
• whether your privacy policy allows the relevant use and disclosure
• whether confidential material should be shared under a non-disclosure agreement
• who within the investor or lender group can access the information

This becomes more important for software, health, education and marketplace businesses, where due diligence often touches sensitive user data.

Trade Marks And IP Ownership

Funding diligence often exposes a hidden problem: the company does not actually own its core intellectual property. Investors want the company, not individual founders or contractors, to own the brand, code, designs and key content.

Before you raise, sort out:

• founder IP assignments to the company
• contractor agreements with clear IP ownership clauses
• employment contracts dealing with created IP
• trade mark searches and, where appropriate, trade mark registration for your brand

Founders often spend months refining valuation and miss this basic issue. If the company does not own the IP, both debt and equity investors may see that as a major risk.

Contracts, Online Sales And Growth Risks For Debt Vs Equities

The main risk is not choosing debt or equity in the abstract, it is choosing a funding model that clashes with how your business actually operates and grows.

How Debt Affects Trading And Cash Flow

Debt can suit businesses with predictable revenue, contracted income or clear short-term working capital needs. It is often attractive for founders who want to preserve ownership.

But repayments change how the business runs. A seasonal ecommerce business, a startup still testing product-market fit, or a software company with long sales cycles may struggle under fixed repayment obligations. Before you sign a contract, stress test the cash flow against realistic sales timing, not best-case growth assumptions.

If you are selling online, your legal position with customers matters too. Consumer law, customer terms, refund settings and service commitments all affect revenue predictability. If the business has to honour customer remedies or delivery commitments under the Consumer Guarantees Act 1993 and the Fair Trading Act 1986, that can tighten cash flow at exactly the wrong time for debt repayments.

How Equity Affects Control And Decision-Making

Equity usually gives the startup more breathing room on cash, but it changes who gets a say. That is the trade-off founders need to evaluate honestly.

An investor may ask for reserved matters, meaning you cannot take certain actions without consent. These commonly cover:

• issuing more shares
• taking on debt above a threshold
• changing the business model
• selling key assets
• approving budgets
• hiring or removing senior executives

These terms are not automatically unreasonable. The problem is agreeing to them without thinking through daily operations and future rounds. If the investor rights are too broad, the company can become slow and difficult to run.

Founders, Employees And Contractor Arrangements

Funding often exposes gaps in internal contracts. Investors and lenders want to know the team is properly tied into the business and the business owns what it is building.

Before you spend money on setup for a raise, review:

• founder agreements and decision-making rules
• employment contracts for key team members
• contractor terms, especially IP ownership and confidentiality
• employee share scheme documents, if any are planned or already promised

If a founder can walk away with source code, customer relationships or the brand, that weakens both debt and equity options.

Leases, Suppliers And Existing Contracts

Growth funding also interacts with the contracts you already have. A commercial lease may limit assignment or changes in control. Supplier contracts may include exclusivity, minimum order quantities or credit terms. Existing bank documents may restrict further borrowing or security.

That matters in real founder moments. You might secure an investor, then discover your current documents require landlord consent, co-founder consent, or lender consent before the deal can complete. Cleaning this up early saves time and negotiation cost.

Future Rounds And Exit Planning

The best funding documents do not just solve today’s cash need, they leave room for the next stage. Debt should not choke off future fundraising. Equity should not leave the cap table so fragmented that later investors lose interest.

Founders should think about:

• whether a new lender will rank ahead of future lenders
• whether investor pre-emption rights are workable in later rounds
• whether conversion mechanics in a note are clear enough for future investors
• whether exit proceeds will be shared in a way that reflects expectations

A simple document now can cause expensive friction later if these issues are left vague.

FAQs

Is debt or equity better for an early stage startup?

Neither is always better. Debt may work if revenue is predictable and the business can service repayments. Equity is often more practical for early stage startups that need time to grow and want to avoid immediate cash pressure.

Can I raise money from friends and family without formal documents?

You can, but it is risky. Even friendly money should be documented clearly so everyone understands whether it is a loan, share investment or convertible instrument, and what rights attach to it.

Will I lose control if I take equity investment?

Possibly, but not always. The level of control you give up depends on the percentage sold and the investor rights in the documents, such as board seats, veto rights and reserved matters.

Can a lender take security over my startup assets?

Yes. A lender may ask for security over company assets and, in some cases, personal guarantees from founders. You should understand exactly what is secured before you sign.

Do I need a shareholders agreement for equity funding?

In most cases, yes. A shareholders agreement helps deal with voting, transfers, future fundraising, founder exits and investor rights. Without one, disputes are more likely when the business grows or circumstances change.
