Types Of Contracts In Australian Business Law

Running a business in Australia can be exciting and rewarding - and yes, there’s some paperwork involved. Getting your contracts right is one of the smartest ways to protect your business, clarify expectations, and set up strong relationships with customers, suppliers, partners and staff.

In this guide, we’ll break down the main types of contracts used in Australian business law, the different forms a contract can take, what to include in your agreements, and which documents most small businesses actually need. We’ll also flag the key laws that affect your contracts so you can stay compliant and avoid nasty surprises.

You don’t have to become a lawyer to use contracts well. With a clear understanding of the basics - and help when you need it - you can put simple, practical documents in place that support growth and reduce risk.

What Is A Contract In Australia?

A contract is a legally binding agreement between two or more parties. To be enforceable, it generally needs four things: an offer, acceptance, consideration (something of value provided by each side) and an intention to create legal relations.

Contracts don’t have to be complicated to be effective. An agreement might be recorded in a formal document, set out in emails, or even made orally. That said, written contracts are strongly recommended for most business arrangements because they’re easier to prove and manage.

It’s also worth remembering that many business relationships are influenced by laws and awards that sit alongside your contracts. For example, employment relationships still need to comply with the National Employment Standards (NES) and any applicable modern award, regardless of what your agreement says.

Common Types Of Contracts Used By Australian Businesses

Here are the key contract types most small and medium businesses come across. Your business might not need every one of these, but you’ll likely use several.

Employment Contracts

An Employment Contract sets out the role, duties, pay and benefits, hours, leave and how either side can end the employment. In Australia, a written employment agreement isn’t legally required in every case, but it’s strongly recommended to avoid disputes and to capture key terms clearly (alongside the NES and any award). If you’re hiring staff, consider a tailored Employment Contract that fits the position and award coverage.

Contractor Agreements

When you engage a freelancer or independent contractor, a Contractor Agreement clarifies pricing, deliverables, timing, confidentiality, IP ownership and how the relationship operates. It also helps distinguish a contractor relationship from employment (a critical legal distinction). If you work with contractors, use a clear Contractors Agreement to set expectations from day one.

Service Agreements (Customer Contracts)

If you provide services - from marketing and design to consulting, trades or professional services - a Service Agreement (or Client Services Agreement) outlines the scope, milestones, fees, payment terms, liability allocation and dispute resolution. This is one of the most useful tools for reducing scope creep and late payments. You can put a tailored Service Agreement in place for one-off projects or ongoing retainers.

Sale Of Goods Terms And Supply Agreements

Product businesses typically need terms that cover pricing, delivery, risk and title (when ownership passes), defects and returns, and limits on liability. Your terms could be embedded in invoices or online checkout flows. For wholesale or more complex arrangements, consider a dedicated supply or distribution contract. Many retailers use Website or Online Shop terms, but you can also implement standalone Website Terms and Conditions to manage online sales and user behaviour.

Commercial Lease Agreements

Leases are contracts too. A commercial lease or licence sets out rent, fit-out, permitted use, make-good, outgoings and the term. Make sure the document matches your business plans (including any options to renew) and that the premises are fit for purpose.

Non-Disclosure Agreements (NDAs)

NDAs help protect confidential information when you’re exploring a new partnership, discussing an investment, or collaborating on a project. A well-drafted Non-Disclosure Agreement can deter misuse and give you remedies if information is shared without permission.

Shareholders, Partnership And Joint Venture Agreements

If you have co-founders or investors, a Shareholders Agreement sets the rules for decision-making, issuing shares, exits and dispute resolution. For non-company structures, a Partnership Agreement covers roles and profit share. If you’re collaborating with another business on a defined project, a Joint Venture Agreement can outline governance and commercial terms.

Franchise Agreements

Buying a franchise? You’ll enter into a Franchise Agreement that’s regulated by the Franchising Code of Conduct. It’s detailed and carries ongoing obligations around fees, branding, operations and termination. Independent legal advice is strongly recommended before you sign (for example, a Franchise Agreement Review).

Licensing And IP Agreements

Where you license your software, content, brand or other IP - or receive a licence from someone else - an IP Licence defines what can be used, how, where, for how long, and on what payment terms. Tailored IP Licence terms are essential for creative and tech businesses.

Forms Of Contract: Written, Oral And Electronic

Australian law recognises several forms of contracts. The best choice depends on the value and complexity of the deal - and how much risk is involved.

• Written contracts: The safest and most common option for business. Clear wording and signatures (physical or electronic) make your agreement easier to prove and enforce.
• Oral contracts: These can be binding, but they’re hard to prove. Avoid relying on verbal agreements for anything important or high value.
• Electronic contracts: E-signatures and online acceptance are widely used and generally enforceable if consent, reliability and identification requirements are met. There are exceptions (for example, some documents and transactions have special rules), so it’s worth understanding how wet ink vs electronic signatures work in Australia.

Some transactions must be in writing (for example, sales of land and most commercial leases). Even where writing isn’t mandatory, choose a written agreement for clarity and risk management.

What Should Every Business Contract Cover?

There’s no one-size-fits-all, but most business contracts should address the following core topics in plain, unambiguous language.

• Parties and details: Correct legal names and ABN/ACN where relevant.
• Scope or deliverables: What’s being supplied, by whom, to what standard, and by when.
• Price and payment: Fees, invoicing, due dates, deposits and what happens if payment is late.
• Term and termination: Start date, end date (if any), renewal options and how the contract can be ended (including for breach or convenience).
• Liability and indemnities: How risks are allocated if things go wrong, and any limits on liability.
• IP and confidentiality: Who owns pre-existing and newly created IP, and how confidential information is protected.
• Warranties and compliance: Any promises about quality or performance, plus compliance with applicable laws.
• Dispute resolution and governing law: Steps to resolve issues (usually negotiation then mediation), and which state or territory’s law applies.
• Signatures/execution: Ensure the person signing has authority. Companies can execute under the Corporations Act or by authorised representatives; execution mechanics matter if you ever need to enforce the agreement.

Strong contracts are clear, fair, and aligned with how your business actually operates. If you use a standard template, get it tailored to your services, pricing model and risk profile rather than trying to make a generic document fit every situation.

Compliance: Which Laws Affect Your Contracts?

Your contracts don’t sit in a vacuum - they must work alongside Australia’s key business laws. Here are the big ones to consider.

Australian Consumer Law (ACL)

The ACL applies to most businesses that sell goods or services to consumers and small businesses. It covers consumer guarantees, refunds, misleading conduct and more. It also prohibits unfair terms in standard form contracts - and as of late 2023, penalties apply if you include unfair terms in many small business contracts. If you use template agreements or online terms, consider a periodic legal check to reduce unfair terms risk.

Employment Law

If you hire staff, you must comply with the NES and any applicable modern award. While a written Employment Contract isn’t strictly mandatory in all cases, it’s the best way to record pay, hours, duties, confidentiality and post-employment restraints in a way that aligns with workplace laws. Casual terms, overtime and rostering should be aligned with award requirements.

Privacy And Data

Not every Australian small business is legally required to have a Privacy Policy. The Privacy Act 1988 (Cth) applies to “APP entities” (generally businesses with annual turnover over $3 million) and some smaller businesses in specific categories (such as health service providers, those trading in personal information, or certain contracted service providers). Even if the Act doesn’t apply to you, many businesses still adopt a clear privacy notice, and platforms or partners may require one contractually. If your business handles personal information, it’s good practice to document what you collect and how you use it, and many businesses publish a Privacy Policy on their website.

Corporations Law And Contract Execution

For companies, the Corporations Act 2001 (Cth) sets out how documents can be validly signed and who has authority to bind the company. Getting execution right can make enforcement much simpler, especially for higher-risk or higher-value deals.

Industry-Specific Rules

Depending on your sector, you may need to meet additional requirements - for example, building and construction licensing, childcare regulations, or financial services rules. In franchising, you’ll need to comply with the Franchising Code of Conduct (including pre-contract disclosure and cooling-off rights). Make sure your contracts reflect any industry-specific obligations that apply to you.

Which Agreements Do Most Small Businesses Actually Need?

Every business is different, but here’s a practical checklist of the contracts most Australian SMEs rely on. Some are “must-haves” for risk management; others are situational and depend on your model.

• Client/Customer Contract: For service businesses, a tailored Service Agreement or Terms of Business that covers scope, fees, timelines, liability and disputes.
• Sales Terms (online or offline): For product businesses, clear terms dealing with orders, delivery, risk, returns and ACL rights. If you sell online, include Website Terms and Conditions that govern use of your site as well as checkout terms.
• Employment Agreements: Written contracts (aligned with the NES and any relevant award) make expectations clear for permanent, part-time and casual staff. Consider role-specific clauses for confidentiality, IP and restraints - your Employment Contract should match the position.
• Contractor Agreements: If you use freelancers or independent contractors, a structured Contractors Agreement reduces misclassification risk and clarifies deliverables, IP ownership and payment.
• NDAs: A short, practical Non-Disclosure Agreement is handy for early-stage discussions with suppliers, potential partners or investors.
• Founders/Investor Agreement: If you have co-founders or plan to raise capital, a Shareholders Agreement sets the rules for ownership, decision-making and exits.
• IP Licence (if applicable): For software, content or brand licensing, an IP Licence defines usage, restrictions and fees.
• Lease Or Licence For Premises: If you occupy physical space, ensure your commercial lease or licence reflects your operations, renewal plans and fit-out responsibilities.

This list isn’t exhaustive, and not every business needs every document. The goal is to prioritise what matches your operations and risk. As your business evolves - for example, adding sales channels or new product lines - your contract suite should evolve with it.

Key Takeaways

• Contracts are the backbone of clear, professional business relationships - and written agreements give you the strongest protection.
• Common contracts include Employment and Contractor Agreements, Service or Client Terms, sales terms for products, NDAs, and founder or investor agreements like a Shareholders Agreement.
• Electronic contracts and e-signatures are generally enforceable in Australia, but some transactions have special rules, so choose the right form for the deal.
• Your contracts must align with key laws, especially the Australian Consumer Law (including unfair contract terms rules), workplace laws, privacy requirements and any industry-specific regulations.
• Not every business is legally required to have documents like a Privacy Policy or a written employment contract in all circumstances, but having clear, tailored agreements is best practice and often expected by customers, platforms and partners.
• Review your templates periodically. As your business grows, your risk profile changes - and your contracts should keep up.
