Mergers And Acquisitions: What Startups And Small Businesses Need To Know

Mergers and acquisitions (often shortened to “M&A”) can feel like something that only happens to big corporates. But if you’re running a startup or small business in Australia, M&A can be a very real part of your growth plan - whether you’re buying a competitor, selling to a strategic buyer, or combining forces with a business that complements yours.

If you’ve been Googling what is mergers and acquisitions, you’re probably trying to understand the basics without getting buried in legal jargon. The good news is that M&A can be broken down into a practical process and a few key deal structures - and once you understand those, you can approach opportunities (and negotiations) with much more confidence.

Below, we’ll walk you through what M&A means in plain English, why smaller businesses use it, the most common ways deals are structured in Australia, and the legal documents and steps you should expect. We’ll also flag some common tax and regulatory issues that can materially affect an M&A deal (so you can raise them early with the right advisors).

What Is Mergers And Acquisitions (M&A)?

At a high level, mergers and acquisitions describe transactions where one business combines with, buys, or takes control of another business.

What Is A Merger?

A merger is typically when two businesses combine into one. In practice, “merger” can mean different things depending on the legal structure and what the parties intend.

For startups and small businesses, a “merger” often looks like:

• two companies agreeing to operate as one group going forward (sometimes under a new structure or brand);
• the owners “rolling” their equity into the combined business (so they keep an ownership stake); and/or
• a restructure where one company ends up owning the other, even if the parties call it a “merger” commercially.

What Is An Acquisition?

An acquisition is usually more straightforward: one party buys another business (or a meaningful part of it).

That “buy” can be done in different ways, but the commercial idea is the same - the buyer gets ownership or control, and the seller gets value (often cash, shares in the buyer, or a mix of both).

M&A Is A Business Strategy (Not Just A Legal Process)

Although M&A involves legal documents and risk management, it’s also a growth strategy.

For example, you might be looking at M&A to:

• enter a new market faster than building from scratch;
• acquire a team or technology;
• secure customers, contracts, or distribution channels;
• create economies of scale (lower costs per unit as you grow); or
• give founders and early investors an exit.

Why Do Australian Startups And Small Businesses Use M&A?

If you’re in the early stages of building a business, M&A can feel like a “later” problem. But opportunities often come up sooner than expected - especially if your business is in a fast-moving industry or you’ve built something unique.

Buying A Business To Grow Faster

Organic growth is great, but it can be slow. Buying an existing business (or part of one) may let you accelerate growth by acquiring:

• an existing customer base;
• supplier relationships;
• systems and processes;
• trained staff; and
• brand awareness and goodwill.

That said, a rushed acquisition can also mean inheriting problems you didn’t price in - which is why proper due diligence matters (more on that below).

Selling Your Business (Or Part Of It) As An Exit Or Growth Move

Not every sale is a “walk away and retire” moment. Many founders sell because it helps them:

• de-risk their personal finances after years of building;
• bring in a bigger partner to scale the business;
• access capital, distribution, or operational support; or
• create a succession plan.

In some deals, founders stay on for a transition period, or retain an ownership stake via shares in the buyer (especially where the buyer is a growing group).

Combining With Another Business To Stay Competitive

Sometimes a “merger” is really about survival and market position. If you and another small business are competing for the same clients and facing the same cost pressures, combining can help you:

• reduce duplicated overheads;
• offer a broader range of products/services; and
• negotiate better supplier pricing due to higher volumes.

The key is to ensure the combined entity has a clear operating model and decision-making structure (and that the paperwork matches that reality).

Common M&A Deal Structures In Australia (And What They Mean For You)

One of the biggest sources of confusion when people ask what is mergers and acquisitions is that the same commercial outcome can be achieved through different legal structures.

Here are the structures you’ll most commonly see for startups and small businesses.

1. Share Sale (Buying The Company Itself)

A share sale is where the buyer purchases shares in the target company from the existing shareholders. The company stays the same legal entity - it just has new owners.

This often appeals to sellers because it can be a “cleaner” transfer of the business as a whole (including contracts, employees, licences, and assets), but it can also mean the buyer inherits the company’s historical liabilities.

In Australia, share sales are commonly documented with a Share Sale Agreement, which sets out the purchase price, what’s being sold, warranties, and the completion process.

2. Asset Sale (Buying Specific Assets Of The Business)

An asset sale is where the buyer purchases selected assets used in the business (for example: stock, equipment, IP, customer contracts, domain names), rather than buying shares in the company.

Asset sales can be attractive for buyers who want to avoid taking on unknown liabilities - but they can be more “piece by piece,” because you often need to assign or re-document key relationships (like customer and supplier contracts).

Asset deals are often documented with an Asset Sale Agreement.

3. Merger-Style Restructures (Combining Ownership)

In smaller deals, a “merger” might be achieved by one company issuing shares to the owners of another company, so everyone becomes shareholders in one combined entity.

This structure can be useful where:

• the parties want a long-term partnership, not a full cash exit;
• cash is limited; or
• the value of the businesses is expected to grow significantly post-deal.

Where there are multiple owners (especially with different roles, decision-making rights, and future exit plans), a tailored Shareholders Agreement can be essential to avoid disputes after the excitement of the deal fades.

4. Earn-Outs And Deferred Consideration

In many startup acquisitions, the buyer and seller disagree on valuation. One common compromise is an earn-out - where part of the price is paid later if the business hits performance targets (like revenue, profit, or customer retention).

Earn-outs can work well, but they’re also a common source of disputes if the targets, measurement method, or operational control aren’t clearly drafted. This is one of those areas where “commercially agreed” terms still need careful legal translation.

5. Vendor Finance And Other “Creative” Funding Arrangements

Not every buyer has the cash upfront. In some small business deals, the seller effectively provides financing by allowing the buyer to pay over time.

This can help get the deal done - but it needs clear payment terms, default consequences, and (often) security arrangements so the seller isn’t left exposed if payments stop.

The M&A Process Step-By-Step (From First Chat To Completion)

M&A can move quickly, especially if both parties are motivated. But most deals follow a similar pathway.

1. Initial Discussions And A Heads Of Agreement

Typically, the parties begin with high-level discussions: what’s being bought, at what approximate price, and on what timeline.

Often, this is followed by a term sheet or Heads of Agreement to document the key commercial terms. Even if it’s “non-binding” overall, it can still include binding clauses (like confidentiality and exclusivity), so it’s worth treating it seriously.

2. Confidentiality And Information Sharing

Once you start exchanging financials, customer lists, code, pricing, or supplier terms, confidentiality becomes crucial.

A properly drafted Non-Disclosure Agreement helps protect your confidential information and sets clear rules about how the other party can use it.

Practically, businesses usually share information through a “data room” (a secure folder of documents). It’s a good idea to keep a record of what was disclosed and when, because disclosures often tie directly into warranty and liability negotiations later.

3. Due Diligence (Finding The Risks Before You Sign)

Due diligence is the buyer’s investigation into the target business. For sellers, it’s also the stage where you want to be organised and consistent, so you don’t lose momentum or credibility.

Legal due diligence usually looks at things like:

• Company and ownership: who owns what, whether there are any shareholder disputes, and whether approvals are needed.
• Key contracts: customers, suppliers, leases, loans, and whether any contracts restrict assignment or change of control.
• Employment arrangements: whether staff are properly engaged and whether entitlements have been handled correctly.
• Intellectual property (IP): who owns the IP, whether contractors assigned it, and whether the business is infringing others.
• Compliance and disputes: regulatory issues, threatened claims, or existing litigation.

If you’re going through a more formal review process, a structured Legal Due Diligence Package can help you work through the common risk areas methodically.

4. Negotiating The Deal Documents

This is where the “headline” price becomes only one part of the deal.

Common negotiation points include:

• Deposit and payment timing: how much is paid upfront vs later (including earn-outs).
• Working capital or stock adjustments: whether the price changes based on stock levels or cash/debt at completion.
• Restraints: whether the seller can start a competing business after sale (and for how long).
• Warranties and indemnities: what the seller promises about the business, and what happens if those promises aren’t true.
• Limitation of liability: caps, time limits, and thresholds for claims.

This stage is also where your broader corporate documents can matter. For example, if you’re a company, your Company Constitution might contain rules about share transfers, approvals, and director powers that affect how the deal can be executed.

5. Completion, Transition, And “Day 2” Planning

Completion (sometimes called settlement) is the moment the ownership transfer actually happens - shares transfer, assets transfer, money is paid, and control changes hands.

But for many small business transactions, the real work starts after completion. You’ll often need a transition plan covering:

• handover of systems, accounts, and supplier arrangements;
• customer communications (especially where relationships are founder-led);
• staff announcements and onboarding into the buyer’s structure; and
• rebranding (if applicable).

Key Legal Documents You’ll See In M&A (And Why They Matter)

Every deal is different, but there are a few documents that come up again and again in Australian M&A - particularly for startups and small businesses.

Core Transaction Documents

• Share Sale Agreement: used where the buyer purchases shares in a company, setting out price, warranties, and completion mechanics (often central to the deal).
• Asset Sale Agreement: used where the buyer purchases business assets (and usually includes a detailed list of what’s included and excluded).
• Deed of Settlement (where there’s a dispute): sometimes deals happen alongside the resolution of a shareholder or commercial dispute, and settlement terms need to be documented clearly.

Supporting Agreements That Often Get Overlooked

In smaller deals, it’s common to focus heavily on the “main” sale agreement and underestimate the supporting paperwork. These documents can be just as important to making the deal work in practice.

• Non-Disclosure Agreement: protects confidential information during discussions and due diligence.
• Deed of Novation: if a key contract needs to be transferred and the other party must agree to substitute one party for another, a Deed of Novation may be needed (especially for major customer or supplier arrangements).
• Assignment documents: commonly used to transfer IP, domain names, or contracts where novation isn’t required.
• Employment agreements and contractor arrangements: if staff are moving across, you may need updated terms, or at least clarity about who employs whom after completion.

Documents That Protect The Business After The Deal

• Shareholders Agreement: particularly important if the seller retains equity, the buyer is bringing in co-investors, or founders are staying on with ongoing ownership.
• Restraint and non-solicitation clauses: help protect the buyer from the seller taking customers, staff, or suppliers immediately after completion (these need to be reasonable to be enforceable).
• Transition services arrangements: if the seller will provide help post-completion (like introductions, training, or operational support), documenting this reduces misunderstandings.

If you’re unsure which documents apply to your situation, it’s usually a sign that the deal structure needs to be clarified first (share sale vs asset sale vs a merger-style restructure). Once that’s clear, the document set becomes much easier to map out.

Tax And Regulatory Issues To Flag Early (So There Are No Surprises)

Even when the legal structure is clear, M&A transactions can have major tax, employee entitlement and regulatory implications. These issues don’t always stop a deal - but they can affect pricing, timing, and what documents you need.

• Tax outcomes (including CGT): selling shares vs selling assets can lead to very different tax results for sellers (including potential capital gains tax). Buyers may also care about whether the purchase price can be allocated to depreciable assets or other categories.
• GST: some business sales may be structured as a “going concern” for GST purposes (if the requirements are met), while others may attract GST on particular asset transfers.
• Stamp duty: depending on what’s being transferred (for example, land or certain “landholder” interests), stamp duty may apply and can be a material cost that needs to be budgeted for early.
• Employee entitlements: on a sale, you’ll need to work through what happens to employees and their entitlements (including leave and redundancy risk) and whether they transfer, are offered new employment, or are paid out.
• Regulatory approvals: some acquisitions require approval or notification (for example, foreign investment rules under FIRB for some buyers, and competition considerations with the ACCC in certain cases).

Because these areas are highly fact-specific, it’s important to get early advice from an accountant or tax advisor (and raise any approval requirements with your lawyer) before you lock in the deal structure or price.

Key Takeaways

• Mergers and acquisitions describe transactions where businesses combine or one business buys another - and they’re common for Australian startups and small businesses, not just corporates.
• When you’re asking what mergers and acquisitions are, it helps to separate the commercial goal (growth, exit, market entry) from the legal structure (share sale, asset sale, or merger-style restructure).
• Share sales transfer ownership of the company itself, while asset sales transfer selected business assets - each approach has different risk and documentation implications.
• Due diligence is where buyers uncover risks and sellers prove the business is as represented; it often drives the final terms of price, warranties, and liability limits.
• Key documents commonly include an Asset Sale Agreement or Share Sale Agreement, plus supporting documents like a Non-Disclosure Agreement and sometimes a Deed of Novation for important contracts.
• If the deal results in ongoing shared ownership, a properly drafted Shareholders Agreement can help prevent disputes after completion.
• In most deals, it’s also worth flagging tax, employee entitlement and regulatory issues early (for example CGT, GST, stamp duty, FIRB or ACCC considerations), because they can affect deal structure, timing and overall cost.
