Business contracts for Australian small businesses, types, clauses and legal traps

You have just won your first serious client, or your first wholesale supplier has emailed their terms and conditions with a note asking you to sign. Or you are on the other side of that exchange, sending out a one-page invoice and hoping it is enough of a contract. Most Australian small business owners think about contracts only when a deal starts to go wrong, and by then the protective work has already been missed. This guide sets out which contracts you actually need at each stage of a small business, what the key clauses should say, and where the law now bites harder than it used to.

What makes a business contract legally binding

Australian law does not require most contracts to be written down or signed before they are enforceable. A contract forms when one party makes an offer, the other accepts it, something of value moves each way (the classic requirement of consideration), and both sides intend to be legally bound. All of that can happen over email, over the phone, or by conduct. A verbal agreement can be a binding contract, which is exactly why written terms are the better practice. Writing is not usually legally essential, but it fixes what was actually agreed before memories and interpretations diverge.

A handful of dealings do carry formal requirements. Franchise agreements must be in writing under the Franchising Code of Conduct, and contracts for the sale of land must generally be in writing and signed. Consumer credit contracts carry their own disclosure obligations. For everything else, the risk of a verbal deal is not enforceability, it is proof: when a dispute arises, whoever can point to a signed document setting out the deal is in a far stronger position than whoever is trying to reconstruct it.

Electronic signing is generally fine. Under s 10 of the Electronic Transactions Act 1999 (Cth), a signature requirement is satisfied by an electronic method that identifies the signer and indicates their intention to be bound, provided the method is as reliable as appropriate in the circumstances. A typed name, a click to accept, or a digital signature service can all bind you, so treat online acceptances as real contracts.

The contracts your business will need, stage by stage

No business needs every document below on day one. The practical question is which ones your current stage of growth makes urgent, and which can wait until the next milestone.

Customer or client agreement: the terms on which you supply goods or services. For a trades business this can start as terms printed on the back of an invoice or quote, and for an online store as website terms and conditions. Consultants and professional services businesses should move to a proper client agreement that covers scope, fees, intellectual property and termination before they take on major clients.
Supplier agreement: the terms on which you buy stock, materials or services. It should deal with delivery schedules, quality standards, payment terms, returns and who bears the risk if goods are defective or late.
Confidentiality agreement (NDA): the document to use before you share business plans, customer lists, financials or product ideas with a potential partner, investor, supplier or contractor. An NDA only protects information it actually identifies and only for the period it runs, so it needs to be drafted to cover the information you will genuinely disclose.
Employment agreement: once you hire your first employee, an employment contract sets out duties, pay, hours and leave, but it cannot undercut the National Employment Standards in the Fair Work Act 2009 (Cth) or the applicable award. You must also give every new employee a copy of the Fair Work Information Statement when they start.
Contractor agreement: if you engage independent contractors, a written agreement helps demonstrate the relationship is genuinely one of contracting. Misclassifying someone who is really an employee as a contractor exposes you to sham contracting claims under the Fair Work Act.
Partnership agreement: if you carry on business with someone else, this document allocates roles, profit shares, decision-making and what happens when a partner leaves. Where there is no agreement, the state Partnership Acts supply default terms that rarely match what the partners actually intended.
Shareholders agreement: for a company with more than one owner, this covers voting, board composition, how shares can be transferred, deadlock and exit. It is not legally required, because the replaceable rules in the Corporations Act 2001 (Cth) apply by default, but the default settings seldom reflect what founders actually agreed.
Franchise agreement: buying or selling a franchise is heavily regulated. The Franchising Code of Conduct requires a written franchise agreement, a disclosure document given before entry, and gives new franchisees a 14 day cooling off period. See the consumer law section below for what changed in 2025.
Commercial lease: renting a shop, office or warehouse involves rent, term, fit-out and make-good obligations, renewal options and assignment rights. Retail leases in most states carry additional statutory protections for tenants that a standard lease form will not mention.
Intellectual property agreement: whoever creates work product owns the copyright in it by default unless the contract says otherwise. If a designer, developer or contractor creates material for you, the agreement should assign that intellectual property to you, and if you grant others a licence to use your own IP, the agreement should say exactly what they may do with it.

The clauses every contract should contain

Whatever the document is called, a well-drafted business contract carries the same set of building blocks. If one of these is missing, the gap usually surfaces only when the relationship sours.

Parties: the full legal names of everyone bound, and for Australian businesses the ABN or ACN. A contract signed by a trading name alone can be hard to enforce against the right entity.
Scope: exactly what goods or services are supplied, what is included, and what is not. Scope disputes are the most common source of contract conflict in small business.
Price and payment: the amount, whether it is GST inclusive, when payment is due, and what happens if it is late, such as interest or suspension of work.
Timelines and milestones: when work or delivery happens, and what either side can do if deadlines are missed.
Intellectual property: who owns anything created under the contract, and what each party may use it for after the contract ends.
Confidentiality: what information is treated as confidential, who may see it, and how long the obligation lasts.
Termination: when and how either side can end the contract, how much notice is required, and what happens to work in progress and money already paid.
Liability and risk: caps on liability, exclusions of certain losses, and who insures what. These clauses have legal limits, discussed below.
Dispute resolution: a cheap step before court, such as negotiation followed by mediation, plus a governing law and jurisdiction clause so everyone knows where a dispute would be heard.

Unfair contract terms: from void terms to penalties

This is the area where the law moved most recently, and where many older templates are now dangerous. Since 9 November 2023, unfair contract terms in standard form contracts are not just void, they attract financial penalties. The regime sits in s 23 of the Australian Consumer Law (the ACL), which is schedule 2 to the Competition and Consumer Act 2010 (Cth).

An unfair term in a standard form consumer or small business contract is void, meaning it does not bind the other party. Since November 2023, proposing such a term, or applying or relying on one, is itself a contravention that can attract a pecuniary penalty. A small business contract is one where at least one party employs fewer than 100 people or has a turnover under $10 million in its last income year, which covers the great majority of Australian small businesses.

A term is unfair if it causes a significant imbalance in the parties' rights, is not reasonably necessary to protect the legitimate interests of the party relying on it, and would cause detriment if applied. The party that drafted the term bears the burden of proving it is reasonably necessary, because the law presumes otherwise. Terms that commonly fall foul include automatic renewal clauses, unilateral price variation rights, and clauses that let one side terminate while denying the other the same right.

The penalties are substantial. For a company, the maximum is the greater of $100 million, three times the benefit obtained from the conduct, or 30 per cent of adjusted turnover during the period of the contravention, and each unfair term counts as a separate contravention. An individual faces up to $2.5 million per contravention. To see the regime in action, in ACCC v JJ Richards & Sons [2017] FCA 1224 the Federal Court declared a range of terms in a waste management company's standard form contracts unfair, including automatic renewal, unilateral price variation, credit terms, indemnity and termination clauses, across some 26,000 customer contracts.

Two related consumer law points matter for every business that sells to consumers. The consumer guarantees in the ACL cannot be excluded: s 64 of the ACL voids any term that purports to restrict or modify them, so a template that says "no refunds" or "all sales final" is unenforceable against a consumer. And s 18 of the ACL prohibits misleading or deceptive conduct in trade or commerce, which extends to what your standard terms and marketing materials say.

The laws that override whatever your contract says

Even a carefully drafted contract operates inside a framework of laws that neither party can contract out of. A few of these bite small businesses most often.

Fair Work law: the National Employment Standards set minimum entitlements for all employees, and an employment contract, award or enterprise agreement cannot provide less than those standards. Contracts also cannot undercut an applicable modern award, and the Fair Work Act contains general protections against adverse action that a termination clause cannot waive.
Privacy law: the Privacy Act 1988 (Cth) generally applies to businesses with annual turnover above $3 million, and to some smaller businesses as well, such as health service providers and businesses that trade in personal information. If you collect customer data, your contracts with customers, staff and data processors need to sit inside the Australian Privacy Principles.
Franchising law: the Franchising Code of Conduct, which is a mandatory industry code, took its current form on 1 April 2025. It requires franchisors to give prospective franchisees a disclosure document and a copy of the franchise agreement in the form in which it is to be executed, and it gives new franchisees a 14 day cooling off period after entering the agreement. Breaches can attract civil penalties, currently up to 600 penalty units per contravention.
Consumer credit and financial services: if your business lends money, offers payment plans that constitute credit, or gives financial advice, licensing and disclosure obligations under the National Consumer Credit Protection Act 2009 (Cth) or the Corporations Act 2001 (Cth) override whatever your paperwork says.

Templates: where they work and where they stop

Downloaded templates have a genuine place. For a low value, one-off deal, a simple NDA, or a starting point for terms you will refine, a reputable template can save real money. The line is crossed when the template is doing work it was never built to do.

Templates are the wrong tool when the deal is high value or ongoing, when intellectual property is being created or licensed, when you are hiring staff or engaging contractors, and when the contract type is regulated, such as franchises, leases and consumer credit. A template also ages badly. Terms drafted before November 2023 will not reflect the unfair contract terms penalties, a template written for another country will not reflect Australian consumer guarantees, and a template copied from a competitor's website comes with none of the thinking that produced it.

The most common template failure is not the document itself but the assumption that signing it is the end of the process. A template needs to be checked against your actual business: the parties' names and ABNs, the scope of what you really supply, who owns the work product, and whether each clause would survive the unfair contract terms test if a court looked at it.

When to have an Artificer Legal lawyer look at your contracts

The judgement calls in this area are exactly the ones a template cannot make for you. Whether a term is reasonably necessary to protect your legitimate interests, and therefore safe under the unfair contract terms regime, is a legal assessment that depends on how your contract is used. Whether a worker is an employee or contractor is a test the courts apply to the whole relationship, not a label you can choose. Whether the default replaceable rules under the Corporations Act actually match what your co-founders agreed is a question that only a document tailored to your situation can answer.

An Artificer Legal lawyer can review your standard terms before you send them out, redraft the clauses that would not survive scrutiny, and tell you which of your contracts genuinely need to be bespoke: a shareholders agreement, a partnership agreement, a franchise or lease, or an employment contract for a senior hire. That review is usually the cheapest insurance you will buy, because it happens before a dispute, a regulator, or a tribunal decides the question for you.

The contract most likely to cost you money

The document that poses the greatest financial risk to an Australian small business is not the negotiated deal with a big client. It is the standard form contract you hand out on repeat: your website terms, your invoice terms, your customer agreement. Because those documents are used hundreds of times, a single unfair term embedded in them is a contravention multiplied across every contract you have entered, and since November 2023 that exposure carries real penalties rather than just the loss of the term. If your templates predate that change, or came from another country, they are the first thing to have reviewed.

To summarise the key points: a contract is binding in Australia even without writing, but written terms protect you when disputes arise. The contracts you need track your growth stage, from customer and supplier terms through to employment, partnership, shareholder and franchise agreements. Every contract should cover parties, scope, price, timelines, intellectual property, confidentiality, termination, liability and disputes. Unfair contract terms in standard form contracts now attract penalties of up to $100 million for a company, and consumer guarantees cannot be excluded. Where a deal is high value, ongoing, regulated or involves intellectual property, tailored legal drafting beats any template.
