When an overseas customer does not pay
By Lars Holdgaard, founder of Debitura
Before sending another reminder, decide whether the delay is administrative, commercial or financial. Each needs a different response.
An overdue foreign invoice creates two problems at once. Cash is missing, but so is reliable information. The customer says payment is “in process”, the accounts team blames an approval step, and another week disappears.
That uncertainty is expensive. Research published by the UK Department for Business and Trade in 2025 estimated that late payments affect 1.5 million businesses a year. Among surveyed businesses that said staff spent time chasing late payments, the average was 86 hours a year. When the customer is abroad, distance, time zones and unfamiliar procedures make it even easier to keep waiting without learning anything useful.
The answer is not to send increasingly stern versions of the same email. It is to identify what is actually stopping payment, build a file that can travel, and set a clear point for escalation.
Diagnose the delay before you chase it
A useful first diagnostic is to test the invoice against three possible explanations.
An administrative blockage is usually specific and fixable: the invoice went to the wrong entity, a purchase order is missing, the bank details need verification or the approver is away. Ask what is missing, who owns the next step and the exact date on which payment will be released.
A commercial dispute is different. The customer may challenge the quantity, quality, delivery date or agreed price. Do not argue across a long email chain. Ask for the objection in writing, identify the person authorised to settle it and separate any genuinely disputed amount from the balance that is not in dispute.
Financial risk often produces vague promises rather than a concrete objection. Warning signs include changing payment dates, silence after repeated assurances, requests for more credit or a sudden offer to pay a small amount without a plan. At that point, stop increasing the exposure and move from relationship management to recovery.
Build a file that can travel
Cross-border recovery often slows down because the creditor has an invoice but not a usable case file. Assemble the contract or purchase order, invoices, statement of account, proof of delivery or performance, and the correspondence that shows what the customer accepted.
Check the debtor’s exact legal name, registration details and trading address. A familiar brand name may not be the company that signed the contract. That distinction matters when a demand or claim must be directed to the correct legal entity.
Prepare the file while the facts are fresh. It is much harder to reconstruct delivery records and verbal agreements months later, after the account manager has moved on and the customer has stopped responding.
Replace repeated reminders with one deadline
Once the facts are clear, send a concise final demand. State the amount, what it relates to, the original due date, a new firm deadline and what you will do if payment does not arrive. Attach the documents needed to remove any genuine administrative excuse.
Do not threaten action you will not take. A deadline only has value if it changes the next step. If the customer asks for instalments, require a written acknowledgement of the full debt, fixed payment dates and a consequence for missing the first instalment.
Know when the country changes the route
The practical sequence is broadly familiar in most markets: confirm the debt, demand payment, attempt an amicable resolution and escalate if necessary. The local route behind those steps can differ substantially.
Australia is a useful example. National rules govern collector conduct and corporate insolvency, while limitation periods, civil courts and enforcement procedures vary by state or territory. A UK exporter trying to recover overdue invoices in Australia therefore needs more than another email sent from London. It needs a complete file and local follow-up that fits the debtor, the state and the nature of the claim.
Local escalation is usually justified when the customer has gone silent, the explanation keeps changing, the debt is undisputed but unpaid, assets may be at risk or the claim is approaching a time limit. Acting locally does not mean starting court proceedings immediately. A credible contact in the debtor’s market can often test whether the problem is reluctance, dispute or inability to pay before legal costs are considered.
Protect the next sale as well as the old one
An overdue invoice should change future credit decisions. Review the customer’s credit limit, require a deposit or milestone payments where appropriate, and confirm the contracting entity before the next order leaves the door. Do not let a valuable commercial relationship become a reason to extend the same risk again.
The aim is not to become more aggressive. It is to reduce uncertainty faster. The most useful question is rarely “How many reminders have we sent?” It is “What is blocking payment, and what evidence gives us the strongest next move?”
