The best way to pay overseas suppliers in 2026

Why the cost of paying overseas suppliers is higher than it looks

Most finance teams focus on the headline transfer fee. That fee is the visible line on the statement, and at UK high-street banks it varies widely: some now charge nothing to send an international payment online, while others levy a flat charge or a capped percentage. What is far harder to see is the exchange rate margin embedded in every conversion. Analysis by Key Currency, an FCA-authorised currency broker, estimates that the big banks typically charge 2 to 5 percent in exchange rate costs on a SWIFT transfer above the mid-market rate. On a £50,000 payment, a 3 percent margin costs £1,500 before any intermediary has touched the funds.

SWIFT payments also frequently travel through one or more correspondent banks. Each may apply its own fee, which Wise estimates at roughly $15 to $50 per intermediary bank, deducted silently from the principal, so the supplier receives less than you sent. Because these deductions are not always disclosed upfront, the total cost is often unpredictable until after settlement, when your supplier reports a shortfall.

Speed is a related but distinct cost. Standard SWIFT payments settle in one to five business days, during which the rate can move. The Bibby Trading Places 2026 report found that exchange rate volatility is directly affecting the profitability of 40 percent of SMEs, and that global conflicts have become the top macroeconomic concern for internationally trading businesses, cited by 48 percent in 2026. The most useful metric for comparing methods is the effective transfer rate: divide the sterling your supplier actually receives, converted back at the mid-market rate, by the sterling you sent. The gap from 100 percent is your real cost, and most businesses are surprised by it.

The main methods available to UK businesses in 2026

UK businesses can choose from four broad approaches when they need to pay overseas suppliers: a SWIFT wire through their existing bank, a specialist FX broker or treasury service, a regulated fintech payment platform, or a virtual IBAN arrangement that routes payments over local rails in the destination country. Each sits at a different point on the cost-speed-control spectrum, and the right answer depends on your volumes, currencies, urgency, and existing infrastructure.

SWIFT wires through a high-street bank remain the default because the account is already there and the brand is trusted. The trade-offs are cost and limited transparency: most banks do not show the mid-market rate against the rate they apply, and the total cost is often invisible until after the instruction is submitted. For low-volume, non-urgent payments to established suppliers a bank wire is adequate; for regular or high-value payments it is rarely the most efficient choice.

Specialist FX brokers, including FCA-regulated services such as IFX Payments and Privalgo, offer sharper rates than retail banking, hedging tools such as forward contracts and market orders, and dedicated relationship managers. Their margins sit well below the retail banking equivalent, and they suit businesses that want to lock in a rate for a future obligation while the supplier invoice is in euros or dollars.

Regulated fintech platforms are a credible third category. Providers authorised by the Financial Conduct Authority as Authorised Payment Institutions under the UK Payment Services Regulations 2017 must safeguard client funds and disclose all fees before the instruction is confirmed. Many offer multi-currency accounts, API integration with Xero and QuickBooks, batch payments, and settlement over local rails in many countries, bypassing the correspondent banking layer entirely.

Virtual IBANs and local-rail settlement represent the frontier of cost efficiency. Rather than sending a cross-border SWIFT payment, the payer holds funds in a local-currency account and the provider settles the supplier over their own country's faster payment network. Paying a Vietnamese manufacturer in dong, or a Polish partner in zloty, avoids the SWIFT network, correspondent fees, and conversion at the beneficiary end, and can settle same-day in supported corridors. Nasara Pay is built around exactly this model, enabling UK businesses to settle supplier invoices efficiently across a growing range of international corridors.

How FX risk affects supplier payment strategy

The rate between sterling and a supplier's invoice currency is rarely static. A UK importer who agrees a price in dollars, euros, or renminbi accepts currency risk from order to settlement, and in 2026 that risk is elevated. The Bibby Trading Places 2026 report found that more than half of surveyed UK SMEs have readjusted their FX strategies in response to market instability, with global conflicts now the leading macroeconomic concern for internationally trading firms.

Three straightforward hedging tools require no treasury function. A forward contract fixes today's rate for a payment on a future date, so if you must pay a supplier EUR 80,000 in 90 days, you eliminate the uncertainty over its sterling cost; most brokers and some fintechs offer forwards up to 12 or 24 months. A market order executes the conversion automatically when the rate hits a target you set, useful when you are not under time pressure. And for regular euro or dollar outflows, a multi-currency account lets you settle invoices from the relevant balance and time conversions when the rate is favourable.

The shift in UK SME trade geography is itself a de facto risk strategy. The Bibby report shows a pivot toward Europe, with France cited by 36 percent of UK exporters and Germany by 35 percent of exporters as leading trading markets, ahead of the US at 29 percent, and 57 percent of SMEs pivoting toward Europe and other non-US markets. Settling more of the supply chain in euros rather than dollars or emerging-market currencies reduces the number of exposures to manage. Consolidating payments onto one platform also enables netting: converting one larger sterling amount to cover several euro invoices is cheaper per unit than separate conversions.

FX risk in the payment window itself is often underestimated. A SWIFT payment dispatched on a Tuesday and cleared on Thursday or Friday has been exposed to several days of movement. Faster settlement, over local rails or real-time corridors, compresses that window and narrows the gap between the rate you approve and the rate that executes.

Compliance and regulatory requirements when paying overseas

Every business that pays overseas suppliers from a UK bank account operates within a regulated framework. Under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017, UK payment service providers must collect and transmit information about the originator and beneficiary of every transfer, so you will be asked about the purpose of the payment and the identity of the supplier, particularly for first-time beneficiaries or larger payments. These checks protect UK businesses from being used as unwitting conduits for financial crime.

The FCA authorises and supervises payment institutions in the UK. If you use a non-bank provider, verify that the firm appears on the FCA register as an Authorised Payment Institution or a Small Payment Institution. Authorised firms face capital requirements, conduct rules, and mandatory safeguarding: under the Payment Services Regulations 2017, relevant client funds must be safeguarded, most commonly by segregating them in a designated account at an authorised credit institution so they cannot be commingled with the provider's own money.

On tax, HMRC's reverse charge rules apply when a UK VAT-registered business buys services from an overseas supplier. Rather than the supplier charging UK VAT, the UK business accounts for VAT as if it had supplied the service to itself, recording both an output and an input entry on the same return; for most fully taxable businesses the net effect is nil, but the entries must still be made. The GOV.UK guidance on VAT on services from abroad sets out the rules. Imported goods follow a different regime: Postponed VAT Accounting lets UK importers account for import VAT on their next VAT return rather than paying it at the border, a material cash-flow benefit for large goods importers.

Sanctions compliance applies to every overseas payment. The UK maintains its own autonomous regime, administered by the Office of Financial Sanctions Implementation (OFSI), which operates separately from EU and US lists following Brexit. Paying a supplier in a sanctioned jurisdiction, or a designated person or entity, risks civil or criminal penalties. Reputable platforms screen payments against current OFSI, UN, and other applicable lists automatically, but businesses retain their own legal obligation to check. OFSI publishes an up-to-date consolidated list on GOV.UK.

Choosing the right payment platform: what to look for

Volume and frequency are the most important variables. Businesses making fewer than five overseas transfers a month, each below £5,000, can often manage with their existing bank account. Those making ten or more international payments a month, or single payments above £10,000, will almost always find a specialist platform compelling. The break-even is simple: if the FX margin saving on one payment exceeds the time cost of setting up an account, the switch is worth making.

Operational features matter for anyone with more than a handful of suppliers. Batch functionality lets you upload multiple beneficiaries and amounts in one instruction, cutting entry time and keying errors. Two-factor authentication and approval workflows protect against authorised push payment fraud, and because invoice redirection fraud (criminals intercepting invoices and substituting their own bank details) is a well-documented attack on UK businesses, a platform that requires a second approver for new beneficiaries or large payments is a meaningful control.

Integration with accounting software is often underweighted. When payment data flows automatically into Xero, Sage, or QuickBooks, reconciling supplier payments takes minutes rather than hours. The best platforms expose a full API and maintain native integrations with the major UK packages; for businesses running supplier payment reconciliation at scale, this is a prerequisite for a well-controlled finance function.

Finally, weigh currency coverage and settlement speed in your specific corridors. Ask providers for their all-in cost on your top three pairs, and test settlement times before committing supplier relationships. The best providers give a live quote showing the mid-market rate, their margin, and the expected settlement date before you confirm.

Step-by-step: how to set up a reliable overseas supplier payment process

A documented process is the difference between a finance function that runs smoothly and one that generates emergencies. Start with a supplier payment policy that specifies which platform or account is used for each currency corridor, who may add new beneficiaries, what verification is required before a first payment, and how confirmations reach the team managing supplier relationships. Even a one-page policy removes the ambiguity that enables fraud and error.

Verifying bank details before the first payment to any new supplier is the single most important control. Call the supplier on a number obtained independently of the invoice or email, and confirm the account name, sort code or IBAN, and SWIFT or BIC code. Do not rely on details in an email, which may have been intercepted or spoofed. Record the verification and repeat it whenever a supplier notifies a change to their details.

Once a supplier is verified, automate the workflow. Most platforms let you store approved beneficiaries, schedule recurring invoices, and generate remittance advices automatically. When you reconcile supplier payments at month end, a clean audit trail showing instruction, approval, confirmation, and statement match cuts the time spent chasing discrepancies.

Review your platform and exchange rate costs at least annually, since a provider that was best-in-class 18 months ago may have been undercut or changed its fees. A benchmark comparison using a representative sample of recent payments can surface material savings and gives you leverage to negotiate. For businesses paying in several currencies, a multi-currency account offers natural hedging: settling a euro invoice from a euro balance you already hold avoids a conversion entirely, with no derivative contract or hedging expertise required.

What changes to watch in 2026 and beyond

The infrastructure behind international payments is changing faster than at any point in a decade. The Bank of England's RT2 platform, live since April 2025, uses ISO 20022, which carries richer data alongside each payment, including structured remittance information, purpose codes, and legal entity identifiers. As more overseas central banks and clearing systems adopt ISO 20022, the standard enables straight-through processing without manual matching at the beneficiary end, reducing delays and the risk of funds being returned for insufficient data.

The G20 Roadmap for Enhancing Cross-Border Payments, coordinated by the Financial Stability Board, sets targets for end-2027: making funds available within one hour for 75 percent of cross-border retail payments, and cutting the global average cost of a retail cross-border payment to no more than 1 percent, with no corridor above 3 percent. FSB progress reports note these targets are behind schedule globally, but they are still driving investment in new corridors and infrastructure. Businesses that lock into long-term contracts with expensive providers today may find themselves on the wrong side of a market shift within two to three years.

Compliance requirements are also evolving. OFSI has increased its enforcement activity in recent years, and the Economic Crime and Corporate Transparency Act 2023 introduced a new corporate failure-to-prevent-fraud offence, in force from 1 September 2025 for large organisations. If a supplier operates in or through a jurisdiction on a major sanctions list, a compliant platform will block the payment and you will need legal advice before proceeding. As the geopolitical environment stays unsettled, the number of designated entities and jurisdictions on UK, EU, and UN lists continues to grow, so keeping your compliance function current is not optional for any business with an international supply chain.

Conclusion

How to pay overseas suppliers is ultimately a question of efficiency and risk management. Every percentage point lost to an opaque FX margin or an avoidable intermediary fee directly reduces the gross margin you earn from international supply relationships. The UK market in 2026 offers genuine alternatives to the high-street bank default, with regulated, FCA-authorised platforms providing transparent pricing, fast settlement, and the integrations modern finance teams need. The barrier to switching is lower than most businesses assume.

Start by benchmarking your current all-in cost across your three most frequent corridors. Add up the transfer fees, estimate the FX margin by comparing the rate you received with the mid-market rate on the day, and factor in any intermediary deductions your suppliers reported. Run the same exercise on a representative alternative. The difference is the annual saving available today, without changing supplier relationships or renegotiating contracts. Then build a process that matches your supply chain, with the controls and documentation that protect against fraud and support audit readiness. Nasara Pay is designed to make exactly that process straightforward for UK businesses managing cross-border supplier payments.
