The contract disputes that small businesses face most often are unpaid invoices, work or goods that fall short of what was agreed, arguments over what was in scope, disagreements about whether a party was entitled to terminate, and disputes over liability caps and exclusions. Most can be prevented, or resolved quickly, with clear written terms and a well-kept paper trail.
Below, each pattern is explained with the contract wording that usually decides it and the practical steps that reduce the chance of it happening to you.
1. Late payment and unpaid invoices
The single most common business dispute is simply not being paid. Payment rows often turn on whether an invoice was valid, whether a milestone was reached or whether the customer has a genuine complaint about quality.
Prevention: state payment terms, invoice triggers and interest clearly. Between businesses, the Late Payment of Commercial Debts (Interest) Act 1998 can allow statutory interest and fixed compensation where the contract does not provide a substantial remedy. Chase early and keep records of delivery and acceptance.
2. Defective goods or poor service
Disputes arise when the customer says the goods or services did not meet the specification or the standard expected. Where the contract is silent, statute implies terms: for business contracts, the Sale of Goods Act 1979 and the Supply of Goods and Services Act 1982 imply terms such as satisfactory quality and reasonable care and skill.
Prevention: define the specification, acceptance testing and the process for reporting and fixing defects.
3. Scope creep
Projects grow. When extra work is requested informally and delivered without written agreement, arguments follow about whether it is chargeable. Prevention: include a change control clause and use it, confirming changes in writing with any price and timing impact.
4. Termination disputes
One party ends the contract and the other says it had no right to do so. Terminating without a proper basis can itself be a serious breach, exposing the terminating party to a damages claim. Prevention: set out clear termination rights, notice periods and cure periods, and follow the notice clause exactly when exercising them.
5. Liability caps and exclusions
When something goes badly wrong, the fight often moves to whether a liability cap or exclusion applies. Between businesses, some exclusions must satisfy the reasonableness test in the Unfair Contract Terms Act 1977, and certain liabilities, such as death or personal injury caused by negligence, cannot be excluded. Prevention: draft caps clearly and consider carefully what they cover.
6. Disputes over what the contract actually is
Surprisingly often, the parties disagree about which terms apply, for example where each side sent its own standard terms, or work began before anything was signed. Prevention: agree terms before starting work and make sure your terms are accepted, rather than exchanged in passing.
When a dispute starts
Collect the contract and correspondence, check any notice or dispute clause and time limits, avoid making admissions in heated emails, and set out your position calmly in writing. Contract claims in England and Wales are generally subject to a six-year limitation period, but acting early preserves evidence and options. We help businesses both to draft contracts that avoid these problems and to resolve disputes when they arise.

- Follow notice clauses exactly when terminating.
- Keep a clean paper trail from the start of every contract.
Frequently asked questions
- Is a verbal agreement a binding business contract?
- Often yes, but proving its terms is much harder. Confirming key points in writing, even by email, reduces the risk of disputes about what was agreed.
- What if our standard terms conflict with the other side's terms?
- This is sometimes called the battle of the forms. The terms that apply can depend on the sequence of documents and conduct, so it is better to agree terms expressly before work starts.
- Should we stop work if a customer does not pay?
- Only if the contract allows suspension or the non-payment is serious enough to justify it. Stopping without a right to do so could put you in breach, so check the contract first.
