When the Invoice Goes Unpaid: A Measured Route to Recovery

Few things concentrate the mind of a business owner quite like an invoice that has quietly passed its due date. The work was done, the goods were delivered, the terms were agreed — and yet the money has not arrived. In our experience, the difference between a debt that is recovered swiftly and one that drags on for months rarely turns on the strength of the legal position. It turns on how promptly and how methodically the creditor acts.

What follows is a practical sequence. It is not a script to be followed blindly, because every trading relationship has its own history and its own value. But it is a framework that keeps the pressure proportionate and the paperwork in order.

Begin with the file, not the telephone

Before any reminder is sent, check what was actually agreed. Payment terms are sometimes buried in a quotation, sometimes in a purchase order, and occasionally in nothing more than an exchange of emails. Establish the contractual due date, any interest clause, and whether the agreement requires notice of default before interest can be claimed. Confirm, too, the identity of the debtor: a trading name is not a legal person, and a claim issued against the wrong entity is a claim wasted.

If the customer is a limited company, a quick search at Companies House will confirm the registered name and number. If the customer is a sole trader or partnership, note the individual names. This small administrative step saves considerable difficulty later.

A reminder that leaves the door open

A first reminder should be firm, courteous and entirely factual. Attach a copy of the invoice and a short statement of the account. Assume error before assuming evasion: invoices are mislaid, purchase ledgers are processed in batches, and approvers go on leave. A polite enquiry often produces payment within days and preserves a relationship worth far more than the sum in dispute.

Record the date and method of every communication. If reminders are sent by email, keep them. If a promise to pay is made by telephone, confirm it in writing the same day. This contemporaneous record will be valuable if the matter later requires a court to consider the conduct of both parties.

Interest and fixed compensation

Where the customer is a business and the contract is for goods or services, the Late Payment of Commercial Debts (Interest) Act 1998 may assist. Where the contract provides no substantial remedy for late payment, the Act implies a term entitling the creditor to interest at 8% above the Bank of England base rate, running from the day after the agreed payment date.

The Act also provides for fixed compensation — currently £40 for debts under £1,000, £70 for debts between £1,000 and £9,999.99, and £100 for debts of £10,000 or more — together with the reasonable costs of recovering the debt. A contractual rate, if higher, will usually take precedence. Consumer customers fall outside this regime, so check the status of the debtor before relying on it.

These entitlements should be stated plainly in correspondence, with the calculation shown. A clear arithmetic breakdown is far more persuasive than a general assertion that interest is accruing.

The letter before action

If reminders go unanswered, the next step is a formal letter before action. For debts owed by an individual or a sole trader, the Pre-Action Protocol for Debt Claims applies and prescribes the information the letter must contain, including a statement of account, details of interest, and an enclosed response form. The debtor is ordinarily given 30 days to respond.

The protocol does not apply in the same way where the debtor is a limited company, but the general pre-action obligations still require a clear and fair warning of proceedings, a summary of the claim, and a reasonable opportunity to pay or to explain. A well-drafted letter before action frequently produces payment on its own; it also demonstrates to a court, should the matter proceed, that the creditor behaved reasonably.

If the claim reaches the county court

Money claims in England and Wales can be issued online for sums up to £100,000. Court fees are payable and generally increase with the value of the claim. Where a debtor fails to respond within the permitted time, judgment in default can be requested. Where the debt is defended, the claim will be allocated to a track — most modest debt claims are assigned to the small claims track, where costs recovery is limited and the procedure is designed to be navigated without lawyers.

A judgment is not, by itself, payment. Enforcement may then be required, whether by a warrant of control, a third-party debt order, or a charging order over property. For company debtors, a statutory demand or winding-up petition is a remedy of last resort, appropriate only where the debt is undisputed and the sums justify the cost and the risk.

Keeping the relationship, and the evidence

Many debts are settled by a sensible instalment arrangement. If one is agreed, record it in writing, with dates and amounts, and state clearly what will happen if a payment is missed. Correspondence genuinely aimed at settlement can often be marked without prejudice, which protects both sides' positions if the negotiations fail.

Finally, watch the clock. A simple contract debt is generally subject to a six-year limitation period. Diarise the key dates from the outset rather than relying on memory.

Late payment is rarely solved by a single letter. It is solved by consistent, documented pressure applied at sensible intervals. Where a debt is significant or a defence is threatened, early legal advice will usually cost less than the time spent pursuing it alone.
