TL;DR: A valid contract requires offer, acceptance, consideration, and intention to be legally bound. Get key business agreements in writing — verbal contracts are enforceable but extremely difficult to prove.
Contracts are the foundation of every commercial relationship. Whether you are hiring an employee, engaging a supplier, leasing premises, or selling to a customer, you are entering into a contract. Understanding contract basics protects your business from disputes and ensures you can enforce your rights if something goes wrong.
Many small business owners rely on informal arrangements — handshakes, emails, or verbal agreements. While these can technically be enforceable, they create enormous uncertainty when disputes arise. A well-written contract sets out the parties' expectations clearly, defines what happens when things go wrong, and provides the evidence you need to resolve disputes efficiently.
This guide covers the essentials of business contracts — what makes a contract valid, the key clauses every business agreement should contain, and how contract law varies across seven countries.

In most common law countries (UK, Australia, New Zealand, Canada, USA), a valid contract requires:
Offer: A clear proposal by one party to enter into an agreement on specified terms.
Acceptance: An unconditional agreement to the offer. Any modification of the offer constitutes a counter-offer, not acceptance.
Consideration: Something of value exchanged by each party — money, goods, services, or a promise. A contract without consideration is generally unenforceable.
Intention to create legal relations: Both parties must intend the agreement to be legally binding. Business agreements are presumed to be intended as legally binding; domestic and social arrangements are presumed not to be (though this presumption can be rebutted).
Capacity: Both parties must have the legal capacity to contract — they must be of legal age and not incapacitated. Companies contract through authorised representatives.
In civil law countries (France, Sweden), the requirements are similar but terminology and some rules differ. For cross-border contracts, specify which country's law governs the agreement.
Every significant business contract should include:
Parties: Full legal names and addresses of the contracting entities (companies should be identified by their registered names and company numbers).
Scope of work / deliverables: A clear, specific description of what each party is required to do or provide.
Payment terms: Amount, timing, method of payment, and consequences of late payment (interest, suspension of services).
Term and termination: The duration of the contract and the circumstances under which either party can terminate — both for breach and for convenience.
Liability and limitation of liability: What remedies are available if a party breaches the contract, and any caps on the amount of liability.
Confidentiality: Obligations to keep certain information secret, if applicable.
Intellectual property: Who owns any IP created during the contract — particularly important in services contracts.
Governing law and jurisdiction: Which country's law applies and which courts have jurisdiction to resolve disputes.
Force majeure: What happens if performance is prevented by circumstances beyond a party's control.
Dispute resolution: How disputes will be resolved — negotiation, mediation, arbitration, or litigation.
Verbal contracts are generally enforceable but are very difficult to prove. When a dispute arises, each party typically has a different recollection of what was agreed — leaving a court or arbitrator to decide based on circumstantial evidence.
Some contracts must be in writing to be enforceable by law — these vary by jurisdiction but typically include:
For all significant business relationships, use written contracts. Even for smaller transactions, a brief written summary of the key terms (a Purchase Order or formal email confirming terms) is far better than nothing.

Q: Is an email a legally binding contract?
A: It can be. If an email contains an offer, acceptance, consideration, and demonstrates an intention to be legally bound, it may constitute an enforceable contract. Courts in many countries have held email exchanges to be binding contracts. This is a reason to be careful what you agree to in emails — and also a reason to use formal written contracts for significant transactions, rather than relying on email exchanges.
Q: What is the difference between a contract and an agreement?
A: In everyday usage, the terms are often used interchangeably. Technically, all contracts are agreements, but not all agreements are contracts. An agreement becomes a contract when it has all the required elements: offer, acceptance, consideration, and intention to create legal relations. A "gentlemen's agreement" may be morally binding but legally unenforceable if it lacks these elements.
Q: Can I cancel a contract I just signed?
A: It depends on the type of contract and the jurisdiction. Consumer contracts entered into away from business premises often carry a "cooling off" period (typically 14 days in the UK and EU) during which the consumer can cancel. Business-to-business contracts generally do not have automatic cancellation rights after signing. Check the termination provisions in the contract, and if you need to exit, negotiate with the other party or consult a qualified attorney.
