Commercial invoice disputes commonly concern the amount charged, the quality or quantity of goods or services, delivery, payment terms, or whether the invoice is due at all. Harper James is a UK full-service commercial law firm advising businesses on the laws of England and Wales.
The first option is usually a direct review of the contract, purchase order, delivery records, timesheets, acceptance documents and correspondence. The parties can then negotiate a correction, credit note, partial payment, staged payment plan or agreed set-off. Any settlement should identify the invoices covered, the payment dates, interest treatment, VAT position, and whether the arrangement resolves all related claims. A written agreement reduces the risk of a later disagreement about what was agreed.
A party disputing an invoice should explain the grounds promptly and in sufficient detail. Withholding an undisputed amount while disputing the balance is often more practical than refusing payment in full, although the contract and applicable law govern the position. The parties should also check clauses covering notice requirements, contractual interest, retention of title, suspension of services and dispute resolution.
Mediation involves an independent mediator assisting the parties in reaching their own settlement. It is generally confidential and can address wider commercial issues, such as future supply terms or an ongoing business relationship, rather than only the invoice total. A written settlement agreement should record the agreed payment and the treatment of any remaining claims.
Some contracts require adjudication, expert determination or arbitration before court proceedings. These processes differ in their scope, cost, timing and enforceability. The contract should be checked before starting a claim, particularly where it contains a jurisdiction clause, escalation procedure or requirement to send a formal notice of dispute.
If negotiation and alternative dispute resolution do not resolve the matter, the claimant can issue court proceedings for the debt or other contractual remedy. Before doing so, it should assemble the contract, invoice history, evidence of performance or breach, payment records and relevant correspondence. A compliant letter before action usually sets out the sum claimed, the legal basis, interest, costs and a deadline for response.
A statutory demand is a formal insolvency-related demand and is not simply an alternative invoice reminder. Its use requires care because an improperly issued demand can be challenged and can escalate a commercial disagreement. Where the dispute concerns the underlying debt, the claimant should assess the evidence and the debtor's financial position before choosing a debt recovery or insolvency route.
