Business Partnership Agreement: Key Clauses To Include In Australia

Starting a business with someone else can be exciting. You’re combining skills, sharing the workload, and (hopefully) building something bigger than you could on your own.

But partnerships can also be messy if you don’t set expectations early. Even if you and your business partner are close friends or family, misunderstandings about money, responsibilities, and decision-making can quickly turn into disputes.

That’s where a well-drafted business partnership agreement comes in. It helps you get clear on the key rules of the relationship, protects the business if things change, and gives you a practical roadmap to fall back on when you’re under pressure.

In this guide, we’ll walk you through what a business partnership agreement in Australia usually includes, why it matters for small businesses, and how to set your partnership up for long-term success.

This article provides general information only and does not constitute legal, tax or accounting advice. Because partnership arrangements can have significant tax and financial implications, it’s a good idea to get tailored advice for your circumstances.

What Is A Business Partnership Agreement (And Why Small Businesses Need One)?

A business partnership agreement (sometimes called a partner agreement or small business partnership agreement) is a written contract between two or more partners running a business together.

It sets out things like:

• who owns what (and in what proportions)
• who does what (roles and responsibilities)
• how profits and losses are shared
• how decisions are made
• what happens if someone wants to leave, retire, or the partnership ends

In Australia, you can have a partnership without a written agreement. But that’s usually where trouble starts. If there’s no written partnership agreement, you may end up relying on default rules under state and territory partnership laws, which might not match what you and your partner intended.

A written agreement helps you avoid:

• “I thought we agreed…” problems (verbal arrangements are easy to misremember)
• deadlocks where no one has the power to break a tie
• disputes about money (especially drawings, reimbursements, and reinvestment)
• unclear exit pathways if a partner wants to leave or sell their interest
• business disruption if one partner becomes unwell or can’t work

Most importantly, a partnership agreement is about protecting both the relationship and the business. When things are going well, it can feel unnecessary. But it’s most valuable when things aren’t.

Is A Partnership The Right Structure For Your Business?

Before you draft a partnership agreement, it’s worth checking whether a partnership is actually the right structure for what you’re building.

In Australia, a “partnership” is commonly used for small businesses where two or more people carry on a business together with a view to profit.

Key Considerations For Partnerships

• Shared control: Partners typically share decision-making power (unless your agreement says otherwise).
• Shared profits (and losses): You’ll need a clear approach to distributions and financial responsibility.
• Personal liability risk: In many partnerships, partners can be personally liable for partnership debts and obligations.

If personal liability is a major concern, you might consider operating through a company structure instead (where liability is generally limited), with a Shareholders Agreement to govern the relationship between co-owners.

That said, partnerships can still work well for the right business, especially when the partners have complementary skills and a clear plan for decision-making and money.

Partnership Agreement Vs Shareholders Agreement

A partnership agreement is typically used when you’re operating as a partnership. A shareholders agreement is used when you’ve set up a company and the owners hold shares.

If you’re not sure which structure suits your situation, getting advice early can save you from expensive changes later (especially if you start hiring staff, raising money, or taking on major contracts).

What Should A Partnership Agreement Include In Australia?

There’s no single “one-size-fits-all” partnership agreement. A good agreement reflects how your small business actually runs.

Still, there are some key clauses most Australian partnership agreements should include. Below is a practical checklist of the usual inclusions, with explanations in plain English.

1. Who The Partners Are (And What The Partnership Is)

This sounds basic, but it matters. You’ll want to clearly identify:

• the full legal names and addresses of all partners
• the partnership name (if different)
• the business activities the partnership will carry on
• the start date of the partnership

This section can also confirm whether the partners are operating the partnership on behalf of other entities (for example, a partner might be a company or a trustee).

2. Capital Contributions (Cash, Equipment, Or Skills)

Not every partner contributes the same way. One partner might put in cash, another might contribute equipment, and another might contribute time and expertise.

Your partnership agreement should spell out:

• what each partner is contributing at the start (and when)
• whether contributions are treated as ownership, loans, or expenses
• whether partners must contribute more money later if needed
• what happens if someone doesn’t pay what they agreed

This is a common source of resentment in small businesses, so clarity here makes a big difference.

3. Ownership Percentages (And What They Actually Mean)

Partners often assume ownership is “50/50” because they’re both working hard. But ownership might be based on capital contributions, time commitment, or future buy-in arrangements.

Your agreement should clearly state each partner’s interest in the partnership and how that affects:

• profit share
• voting rights
• entitlement to partnership assets on exit

If ownership is intended to change over time (for example, one partner earns a greater share after hitting targets), document that formula carefully.

4. Profit, Losses, And Drawings

This is where many partnership disputes begin: one partner takes money out, the other thinks it’s unfair, and suddenly trust is damaged.

A strong partnership agreement that Australian businesses can rely on should deal with:

• profit distribution: how profits are shared (and how often)
• loss sharing: how losses are shared and funded
• drawings: whether partners can take regular withdrawals, and any caps or approval rules
• reinvestment: whether some profit must stay in the business (working capital)

If your business has seasonal cash flow, setting sensible rules around drawings can protect the partnership from running out of cash when you need it most.

5. Roles, Responsibilities, And Time Commitment

In small business partnerships, it’s common for one partner to manage sales while the other handles operations, or for one partner to be the “public face” while the other stays behind the scenes.

Your agreement should clarify:

• each partner’s role
• expected hours or time commitments (if relevant)
• who can hire staff, approve suppliers, or sign contracts
• what happens if a partner stops contributing time or effort

This doesn’t need to be overly rigid, but it should reflect reality. If the business grows, you can update the agreement.

6. Decision-Making And Voting

How will you make decisions day-to-day? And what about bigger decisions?

Many agreements split decisions into two categories:

• ordinary decisions (routine spending and operations)
• major decisions (taking on debt, changing business direction, admitting new partners, buying expensive assets)

Your agreement should cover:

• who can make what decisions
• when unanimous consent is needed
• how voting works (one vote each, or weighted by ownership)
• what happens if you reach a deadlock

Deadlock clauses are particularly important for 50/50 partnerships. Without a deadlock process, you can end up stuck and unable to move the business forward.

7. Authority To Bind The Partnership

In a partnership, partners can sometimes commit the business to agreements with customers, suppliers, lenders or landlords. Whether the partnership is legally bound can depend on factors like the partner’s actual or apparent authority, whether the transaction is in the ordinary course of the partnership’s business, and what the other party knew (or should have known).

A partnership agreement can set internal limits, such as:

• spending limits without approval
• restrictions on signing leases or loans
• requirements for multiple signatures on major contracts

Even where a third party may still be able to enforce a contract, these rules help manage internal accountability, clarify consequences between partners, and reduce risk.

8. Confidentiality And Intellectual Property

Your partnership might create valuable assets like:

• brand names and logos
• customer lists
• systems and processes
• software, content, designs, or training materials

Your agreement should clarify:

• who owns intellectual property created during the partnership
• what happens to IP if a partner leaves
• confidentiality obligations (during and after the partnership)

If you’re sharing sensitive information early on (even before you start trading), a separate NDA may also be appropriate in some cases.

9. Restraint Clauses (Non-Compete / Non-Solicitation)

It’s a reasonable concern: what if your partner leaves and starts a competing business using your systems and contacts?

A partnership agreement can include clauses that restrict a departing partner from:

• setting up a competing business within a certain area for a certain period
• poaching clients, suppliers, or staff

These clauses need to be carefully drafted to be enforceable. If they’re too broad, they may not hold up.

10. Bringing In A New Partner

If your business grows, you might want to admit a new partner (or replace someone who leaves).

Your agreement should cover:

• how new partners are approved
• how their buy-in price is calculated
• whether existing partners get a first right to buy additional interest
• how ownership and voting will change

This is also a good moment to think about whether the partnership structure still makes sense long-term, or whether it’s time to incorporate.

11. Exit, Retirement, And Buyout Provisions

This is one of the most important parts of a small business partnership agreement. You don’t want to negotiate a partner exit while emotions are high or your business is under pressure.

Your agreement can set out a clear exit pathway, including:

• how a partner can resign (and required notice)
• how the partnership interest is valued (valuation method)
• payment terms for the buyout (lump sum vs instalments)
• what happens if a partner dies or becomes incapacitated
• whether partners can transfer their interest to someone else

For many small businesses, a structured buyout clause is what keeps the business alive when a partner leaves.

12. Dispute Resolution

Disputes don’t always mean your partnership is failing. They’re often just a sign that you need a process for working through disagreements.

A dispute resolution clause might include steps like:

• good faith negotiation
• management meeting within a set timeframe
• mediation with an independent mediator
• arbitration or court (as a last resort)

Even having a basic process in place can stop disagreements from escalating into business-ending conflicts.

Common Mistakes We See In Small Business Partnership Agreements

Most partnership issues aren’t caused by bad intentions. They’re caused by vague arrangements and assumptions.

Here are some common mistakes we often see when small businesses try to “keep it simple”:

• No agreement at all: relying on informal promises until a dispute forces you into damage control.
• Copying a generic template: the agreement doesn’t match how your partnership actually works, or it misses key issues like exit pathways and deadlock.
• Unclear money rules: no distinction between profit distributions, drawings, reimbursements, and loans.
• No plan for illness or absence: if one partner can’t work for 3 months, what happens to workload and income?
• Not addressing restraint and confidentiality: business goodwill can walk out the door if you don’t set clear boundaries.
• Not updating the agreement: the business changes (new staff, new services, new locations), but the agreement stays stuck in year one.

A good partnership agreement isn’t about expecting the worst. It’s about building a structure that supports the business through change.

What Other Legal Documents Might Your Partnership Need?

Your business partnership agreement is a key foundation document, but it’s rarely the only one you need.

Depending on your business model, you may also need:

• Customer terms: clear terms reduce disputes and set expectations from day one, especially if you provide services or deliverables under ongoing arrangements.
• Supplier or contractor agreements: useful if you’re relying on external providers to deliver part of your product or service.
• Employment contracts: if you’re hiring staff, a properly drafted Employment Contract helps clarify pay, duties, confidentiality, and termination processes.
• Privacy compliance documents: if you collect personal information (like customer contact details, enquiries, email lists, or online orders), you’ll likely need a Privacy Policy.
• Website legal terms: if you run a website or online store, Website Terms and Conditions can help set rules for site use, limits of liability, and key customer expectations.

And if you decide to move from a partnership to a company structure as you grow, you might also consider documents like a Company Constitution (to set internal governance rules) alongside a shareholders agreement.

The best approach is to think of your legal documents as a “toolkit” that supports how your business actually operates - not paperwork for the sake of it.

Key Takeaways

• A written business partnership agreement helps small businesses avoid disputes by setting clear rules for ownership, money, decision-making, and exits.
• If you don’t have an agreement, you may be relying on default partnership laws that may not reflect what you and your partner intended.
• Strong partnership agreements typically cover capital contributions, profit and loss sharing, roles, authority to bind the business, dispute resolution, and buyout/exit provisions.
• Deadlock and exit clauses are especially important for 50/50 partnerships, where disagreements can otherwise stall the business.
• Your partnership agreement should work alongside other essential documents like customer terms, employment contracts, and privacy/website policies (depending on how your business operates).
