The best way for UK businesses to pay overseas suppliers

Last update: February 25, 2026

Contents

Payment processing delays a shipment. And delayed shipments mean a delay in revenue. This often happens when a supplier follows up because the amount received does not match the invoice. And that’s because currency conversion costs quietly shrink margins.

If your business pays suppliers abroad, you have likely experienced one or more of these issues.

The way you pay suppliers abroad determines how much control you have over exchange rates, how quickly funds arrive and how predictable your costs are. Over time, those factors affect cash flow planning, supplier trust and your ability to scale internationally without unnecessary complexity.

This guide explains the best way to pay overseas suppliers, compares fees and transfer speed in practical terms and outlines what to prioritise if you want faster payments, clearer costs and fewer surprises.

Key takeaways:

Total cost matters more than the headline fee: Transfer fees only tell part of the story. FX mark-ups, intermediary bank deductions and forced currency conversions often account for most of the cost when paying overseas suppliers, especially on higher-value payments
Predictable delivery times protect supplier relationships: Choosing a method with clear, reliable settlement times reduces delays, follow-ups and operational friction for both sides
Paying suppliers in their local currency reduces disputes and can lower prices: Local-currency payments help suppliers receive the exact invoiced amount and avoid unexpected FX losses
FX timing directly affects cash flow and margins: Holding and converting funds in advance gives businesses more flexibility and makes international costs easier to plan
Multi-currency payment accounts offer the most balanced solution for regular payments: For UK businesses that frequently pay overseas suppliers, they provide clearer costs, faster delivery and greater FX control than banks, cards or wallets

Open a World Account and manage overseas supplier payments in multiple currencies.

What UK businesses need when paying overseas suppliers

Before comparing payment methods, it helps to be clear about what actually matters in day-to-day operations.

Cross-border payments can cost up to 10 times as much as domestic payments. However, the cheapest option on paper is rarely the most affordable in practice and speed alone means little if costs and timing remain unpredictable.

1. Low and transparent fees

The headline fee on an international payment rarely reflects the actual cost.

Additional charges often appear elsewhere in the process. Exchange rate mark-ups, intermediary bank deductions and forced currency conversions can all increase the final cost of paying a supplier.

UK SMEs lost £2.8 billion to hidden FX mark-ups and unclear fees. In many cases, these costs only become visible after the payment reaches the recipient.

For businesses making regular overseas payments, this lack of transparency makes accurate cost forecasting difficult. Over time, even small FX margins can quietly reduce profitability and make month-to-month results harder to explain.

When paying overseas suppliers, UK businesses should account for:

Exchange rate margins, not just advertised transfer fees
Intermediary or correspondent bank charges
Forced currency conversions
Differences between the amount sent and the amount received

2. Fast and predictable delivery times

Suppliers plan production, shipping and fulfilment around when they expect funds to arrive. Delays caused by cut-off times, correspondent banks or manual checks can disrupt those plans and strain commercial relationships.

90% of UK businesses experience payment delays, with 44% reporting worsening delays.

Unclear delivery times also create extra work for finance teams. Chasing payments, reconciling delays and responding to supplier queries all take time and attention away from core operations.

International supplier payments can arrive on the same day or take several working days, depending on the payment method, the currencies involved and the number of banks involved.

What matters most is knowing when funds will arrive and being able to rely on that timing.

3. Paying suppliers in their local currency

Most overseas suppliers prefer to receive payments in their own currency.

Local-currency payments reduce confusion, protect supplier margins and minimise disputes emerging from unexpected currency conversions on receipt. When suppliers receive the exact invoiced amount, reconciliation becomes simpler for both parties.

Paying in a supplier’s local currency reflects a more considered payment setup. It simplifies the relationship and avoids shifting currency risk onto the supplier without agreement.

In China, for example, paying suppliers in renminbi (RMB) can confer advantages. Chinese vendors often build a buffer into their quotes when they expect to be paid in USD or GBP to cover FX risk and conversion fees. By offering to pay in RMB, UK importers may negotiate better pricing from Chinese suppliers.

4. Cash flow and foreign exchange control

Foreign exchange timing affects margins.

Being forced to convert currency at the point of payment removes control over exchange rates and exposes businesses to short-term market movements. For importers and high-volume payers, this can materially affect costs.

Holding and converting currency on your own terms separates payment timing from conversion timing. That flexibility improves cash flow visibility, reduces pressure to transact at unfavourable rates and makes international costs easier to plan.

The main ways UK businesses pay overseas suppliers

UK businesses generally rely on four payment routes when paying suppliers abroad. Each works very differently once you look beyond the surface, especially in terms of total cost, delivery time and control over foreign exchange.

1. International bank transfers (SWIFT)

Traditional international bank transfers depend on the SWIFT network. While SWIFT provides the messaging layer, the funds themselves move through a chain of correspondent and intermediary banks before reaching the supplier.

In practice, this introduces cost and uncertainty.

What typically affects cost:

Transfer fees charged by the sending bank
Deductions applied by intermediary or correspondent banks
Exchange rate mark-ups built into the currency conversion

On higher-value payments, FX costs usually dominate. Even a slight percentage difference on a £10,000 supplier invoice can add hundreds of pounds to the final cost before banks apply fixed fees and deductions.

Delivery times:

One to three business days on major currency corridors
Longer settlement times when multiple correspondent banks are involved
Payments to markets such as China or parts of Southeast Asia often take several working days
Additional delays can occur if compliance checks are triggered

International bank transfers can work, but they offer limited visibility over final cost and timing.

When international bank transfers make sense

SWIFT transfers are generally suitable when:

Payments are occasional rather than frequent
Speed is not critical
Cost predictability and FX control are lower priorities

For regular supplier payments, the layered fees and variable delivery times make this one of the least predictable options.

2. Card payments for overseas suppliers

Some overseas suppliers accept debit or credit card payments, particularly for smaller invoices or ad hoc purchases.

Cards are fast at the point of authorisation, but they are expensive for business-to-business payments.

What typically affects cost

Card processing fees charged to the supplier, often 2.5%–6% of the transaction value
Additional FX conversion margins applied by card issuers on foreign-currency payments

Because these fees are percentage-based, costs rise quickly as payment values increase. On a £5,000 invoice, card and FX charges combined can easily reach several hundred pounds.

Settlement considerations:

Authorisation is instant
Funds typically reach the supplier’s bank account one to three business days later
Suppliers may face further costs when withdrawing funds

For suppliers managing tight cash flow, the settlement delay and high fees can be an issue.

When card payments make sense

Paying overseas suppliers by card usually works best when:

Payment amounts are small
Payments are one-off or infrequent
Convenience matters more than total cost

Cards are rarely suitable for regular or high-value payments to overseas suppliers.

3. Online payment platforms and digital wallets

Online payment platforms and digital wallets offer an alternative to traditional bank transfers by routing payments through their networks rather than through correspondent banks.

For many businesses, this means quicker setup and fewer manual steps, especially for cross-border online payments.

What to expect:

Fees are usually charged as a percentage of the payment value and often include currency conversion
Some fintech providers offer narrower FX pricing, with tighter spreads combined with flat or corridor-based fees, which can reduce costs compared to traditional bank transfers
Pricing structures vary significantly by platform, currency and destination, making it important to review the full cost rather than just headline fees

Speed and delivery:

Transfers between users on the same platform are often instant or near-instant
Payments sent to a supplier’s local bank account typically arrive within one to two business days
Platforms may delay or temporarily hold funds for risk, compliance or verification checks, particularly on larger or unfamiliar transactions

Practical limitations:

Not all overseas suppliers accept wallet payments, especially established B2B vendors
Transaction size limits may apply
Recipient-side fees or withdrawal charges can reduce the amount the supplier ultimately receives

When digital wallets make sense

Digital wallets tend to work best when:

Payment amounts are relatively small
Both parties already use the same platform
The supplier accepts wallet payments without adding extra charges

For larger or repeat supplier payments, percentage-based fees and acceptance constraints often make digital wallets less practical than other options.

4. Multi-currency business accounts

Businesses that pay suppliers across multiple markets use multi-currency accounts to manage international payments more effectively.

Instead of converting currency each time a business makes a payment, these accounts let companies hold balances in multiple currencies and pay suppliers directly from those balances.

Payments are typically sent through local banking systems in the destination country, rather than routed through the SWIFT correspondent network.

This setup changes how both cost and timing work in practice.

Cost structure:

Foreign exchange margins are usually closer to the mid-market rate, reducing the cost of each conversion
Transfer fees are generally low or fixed, with some payments carrying no transfer fee
Local payment routing avoids intermediaries’ deductions, so payments arrive in full

As a result, suppliers receive the exact invoiced amount, which simplifies reconciliation and reduces payment disputes.

Speed and predictability:

Payments to suppliers in Europe often arrive the next working day through SEPA
UK-to-US payments sent via domestic US rails are commonly clear within one business day
Payments into Asian markets are materially faster when sent locally, rather than passing through multiple correspondent banks

Separating currency conversion from payment execution also gives businesses more control over timing. Businesses can convert funds when rates make sense and hold them until payment is due, improving cash flow visibility and planning.

When multi-currency accounts make sense

Multi-currency business accounts work best for businesses that:

Pay overseas suppliers regularly
Need clearer, more predictable international payment costs
Want greater control over when and how they convert currency

For many UK businesses trading internationally, this approach provides the most consistent balance of cost efficiency, delivery speed and operational control.

Comparison table: fees, speed and FX control

To make these options easier to compare, the table below sets out the key differences between the main payment methods:

Payment method	Typical fees	Speed	FX control	Best for
International bank transfer	Transfer fees plus FX mark-ups and intermediary deductions	2–5 business days	Low	Occasional payments
Card payments	Card FX fees and supplier surcharges	Same day to 2 days	Very low	Small, ad-hoc payments
Online wallets	Platform fees and FX spreads	1–3 business days	Limited	Low-value digital payments
Multi-currency business account	Transparent FX pricing, fewer hidden fees	Same day or next day in many corridors	High	Ongoing overseas supplier payments

Common mistakes UK businesses make when paying overseas suppliers

Even experienced UK businesses run into avoidable issues when paying overseas suppliers:

Focusing only on transfer fees: Many businesses compare payment methods based on headline transfer fees alone. In practice, foreign exchange mark-ups often account for a much larger share of the total cost, especially on higher-value payments
Overlooking intermediary bank deductions: When payments pass through intermediary banks, deductions can reduce the amount a supplier receives. This often leads to follow-up emails, payment delays and invoice mismatches that take time to resolve and can disrupt production or shipping schedules
Using the same payment method for every supplier: Not all suppliers, currencies or payment corridors behave the same way. A method that works well for a European supplier may be slow or expensive for payments into Asia or North America

Waiting to review payment setup until problems arise: Many businesses only revisit their international payment setup after delays, disputes or margin pressure appear. By that point, the impact has already affected cash flow and supplier relationships
