Cross-Border Payments for UK Businesses: A Practical Guide

The first article in this series examined the machinery of international payments. This one is about decisions: how a UK business that invoices foreign customers or pays foreign suppliers should actually arrange its affairs. The difference between a well-structured setup and an unexamined one is rarely dramatic on any single payment — and quietly substantial over a year.

Start with your corridors, not your bank

Every recommendation in international payments depends on your corridors: which currencies, which countries, which direction, what sizes, how often. A business receiving €30,000 a month from EU customers has a completely different optimal setup from one paying two US software invoices a quarter. So before comparing providers, write down twelve months of reality: every currency you touched, the total volume in each, the typical payment size, and whether you were sending or receiving.

Three patterns cover most UK businesses:

• Euro-centric. Trading mostly with the EU. Your priorities are SEPA access and a euro account. This is the simplest pattern to optimise.
• Dollar-inclusive. Trading with the US or with international customers who prefer to deal in dollars. You need genuine USD receiving capability, and dollar conversion is probably your largest hidden cost.
• Multi-corridor. Selling globally, often through platforms. You need a provider with broad currency coverage and you should think hardest about consolidation and conversion timing.

Receiving: get paid like a local

The cardinal rule for receiving international payments: make it as easy as possible for your customer to pay you through their domestic system. Every border your customer's payment has to cross adds cost, delay and failure modes — and customers deduct intermediary fees from your invoices.

The practical tool is the multi-currency account with local receiving details. Modern providers — and increasingly the banks themselves — can give a UK business a euro IBAN reachable through SEPA, US account and routing numbers reachable through the American ACH system, and similar local details in other major currencies. Your German customer pays a euro account by SEPA transfer; free or nearly so, arrives same day or next. Your American customer pays what looks to them like a domestic account. Nobody sends a "wire" unless they truly have to.

Two disciplines make this work:

• Invoice in the currency you have arranged to receive, and print the correct local payment details on the invoice itself. An invoice that offers a dollar price but only a sterling IBAN forces the worst outcome: your customer's bank does the conversion, at their margin, with you paying the deductions.
• Decide what happens to foreign balances. Convert on arrival for certainty; hold and convert in planned batches for better rates and lower per-conversion costs; or hold to pay out in the same currency — the perfect hedge is matching your euro income to your euro costs, which involves no conversion at all.

Sending: precision prevents delay

For paying international suppliers, most of the value is in operational discipline rather than provider choice:

1. Collect complete beneficiary details once, carefully. The account name exactly as the bank holds it, the IBAN or account number, the correct routing code for the country, the beneficiary's full address, and a clear payment purpose. The majority of delayed payments are delayed by incomplete or mismatched details triggering manual compliance review.
2. Beware of first-time payments to new beneficiaries — from a fraud standpoint. Invoice fraud, in which a supplier's "new bank details" arrive by compromised email, is one of the most damaging attacks on SMEs. Verify new details through a second channel — a phone call to a number you already had — every single time, without exception. No legitimate supplier objects.
3. Choose the charging option consciously. "OUR" when the beneficiary must receive the exact amount; the cheaper shared option only when a small shortfall is tolerable.
4. Time payments around cut-offs, weekends and destination holidays. A payment sent Friday afternoon to a country whose Monday is a public holiday can lose four days for no reason at all.

The FX conversation nobody has

Currency conversion is, for most internationally trading SMEs, the largest single payments cost — and the least examined, because it never appears as a line item. The margin is embedded in the rate.

The discipline is simple to describe: at the moment of any significant conversion, compare the rate you are offered with the mid-market rate, which any currency site will show you. The gap, expressed as a percentage, is your true cost. Banks have historically charged small businesses 2–4% on this measure; specialist providers commonly charge 0.3–1%. On meaningful volume the difference funds real things.

Beyond the margin, three practices are worth adopting:

• Consolidate conversions. Ten small conversions cost more than one large one. If cash flow allows, batch.
• Separate conversion decisions from payment decisions. You can often convert when the rate is sensible and pay when the invoice is due, rather than doing both in one forced moment.
• Treat forward planning as risk management, not speculation. If you know you will need dollars in three months, some providers let a business agree a rate today for delivery then — a forward contract. Used to make costs predictable, this is prudent; used to bet on rate movements, it is gambling with the company's money. A business should decide which currency risks it simply accepts, which it eliminates by matching income to costs, and which it locks with forwards — and write that decision down as policy. (On regulated products, take advice from your accountant or a regulated adviser; we speak here as practitioners of process, not as financial advisers.)

Choosing providers: the questions that matter

Whether you are talking to a high-street bank or a fintech specialist, the same short list of questions separates the serious from the glossy:

• What is your total cost on my actual corridors — explicit fees plus FX margin measured against mid-market — on a realistic example payment?
• Can I have local receiving details in the currencies I invoice in?
• What tracking do I get on outbound payments?
• Is my money safeguarded or protected, and how? (UK e-money and payment institutions must safeguard client funds — segregated from their own money — which is a different protection from a bank's FSCS deposit cover. Understand which regime applies to each balance you hold.)
• What happens operationally when a payment fails or is delayed — is there a human, and what can they see?

Most businesses land on a sensible hybrid: a UK clearing bank as the backbone, with a specialist provider carrying the high-volume corridors where its pricing and local rails earn the traffic.

An annual half-day that pays for itself

Once a year, run the audit: pull every international payment, total the explicit fees, sample a dozen conversions and measure them against the mid-market rate on the day, count the delays and shortfalls, and price the whole picture against two alternative providers. It is half a day of work. We have rarely seen it fail to pay for itself many times over — and it is exactly the kind of measurable, process-first exercise that separates businesses that manage their operations from businesses that merely experience them.
