Paying US Suppliers from the UK: USD Payment Options Compared

UK businesses that source from the United States face a persistent friction: your supplier invoices in USD, but your bank account is in GBP. The gap between those two currencies is where time, fees, and administrative overhead accumulate. Whether you are a British importer paying American manufacturers, a UK agency settling invoices with US software vendors, or a trading company managing multi-market supply chains, the method you choose to pay US suppliers in USD directly affects your margin and your supplier relationships.

This guide compares the real costs, speeds, and practical trade-offs of the most common USD payment methods available to UK businesses in 2026 — and explains where a USD-denominated virtual card fits into the picture.

Why More UK Businesses Are Paying US Suppliers in USD

The US remains the UK's single largest trading partner for both goods and services. According to recent trade data, US-bound business spending from the UK runs into tens of billions of pounds annually — spanning imports, SaaS subscriptions, professional services, and contract manufacturing.

For US suppliers, the preference is clear: they invoice in USD because it eliminates their own foreign exchange exposure. When a UK business attempts to pay in GBP, the supplier either declines or builds the FX risk into their pricing. Paying in USD is not a choice — it is the default expectation for any serious US supplier relationship.

The challenge is that most UK businesses still rely on traditional banking rails to move GBP into USD. Those rails were designed for an era when international payments took days and cost pounds. In 2026, there are faster, cheaper alternatives — but choosing the right one depends on how often you pay, how much you pay, and whether you want to hold USD balances or convert on the fly.

The Real Cost of Paying US Suppliers from the UK

To understand which payment method makes sense, start with the total cost — not just the published fee, but the hidden layers that rarely appear on a bank statement.

A £10,000 payment to a US supplier via traditional SWIFT transfer typically incurs:

An outgoing transfer fee: £20–£40
Intermediary bank charges: £10–£30 (deducted from the transferred amount, so the supplier receives less than expected)
The FX spread: banks typically add 2–4% to the mid-market rate, which on £10,000 can mean £200–£400 in hidden cost
Total realistic cost: £250–£470 for a single payment

Business credit cards denominated in GBP charge a foreign transaction fee of 2.5–3% on every USD transaction. On a £10,000 supplier payment, that is £250–£300 — and the FX rate applied by the card network is rarely the most favourable available.

For UK businesses making regular USD payments, these costs compound quickly. £500 per payment, twice a month, equals £12,000 annually in avoidable fees.

The most efficient payment method, therefore, is the one that minimises three variables: the FX spread, the transfer fee, and the time your finance team spends managing the process.

Comparing the Top Platforms for USD Payments from the UK

The UK market now has multiple specialised platforms for international business payments. Each serves a different use case.

Platform	Best For	FX Fee	Speed to Supplier	USD Virtual Card	Multi-Currency Wallet
Traditional Bank (HSBC, Barclays, Lloyds)	Large, occasional transfers	2–4% (spread) + £20–£50 fee	2–5 business days	No	Limited
Wise Business	Small, frequent transfers	0.4–1%	Same day	No	Yes
Airwallet / Revolut Business	Holding EUR and USD balances	0.5–1.5%	Same day	Limited (Revolut only)	Yes
PhotonPay	B2B supplier payments at scale	Competitive	Instant (card) / 1–2 days	Yes (USD-denominated)	Yes

Traditional Banks — Reliable but Expensive

High-street banks remain the default for many UK businesses, particularly for large, infrequent transfers. The advantages are familiarity and the ability to move very large sums in a single transaction.

The disadvantages are equally clear: multi-day settlement, opaque intermediary fees that reduce what the supplier actually receives, and FX spreads that are significantly wider than specialist platforms. For businesses making regular USD payments, the cumulative cost makes traditional banking an increasingly difficult choice to justify.

Wise Business — Great for Small Transfers

Wise (formerly TransferWise) is widely used by UK freelancers and small businesses for its transparent exchange rates and low fees. For ad-hoc USD payments in the £500–£5,000 range, it is often the most cost-effective option.

The limitations become apparent at scale: Wise does not issue USD-denominated virtual cards for business payments, which means every payment still requires a manual bank transfer. There are also limits on the size of individual transfers, and the platform is optimised for individuals and SMEs rather than businesses managing dozens of suppliers across multiple markets.

Airwallet and Revolut Business — Multi-Currency Holding

Airwallet and Revolut Business both allow UK companies to hold USD balances alongside GBP and EUR, avoiding the need to convert currency before every payment. This is useful for businesses with irregular USD inflows that want to time their conversions.

Revolut Business also issues virtual cards, though the primary focus is consumer-facing expense management rather than B2B supplier payments. For businesses that need to issue separate cards for each supplier, set individual spending limits, and track payments across a multi-market supply chain, a generalist multi-currency account may not offer the control and visibility required.

PhotonPay — Built for B2B Supplier Payments

PhotonPay takes a different approach: instead of moving USD through the banking system, it issues USD-denominated virtual corporate cards that pay US suppliers directly on the Visa and Mastercard networks.

Key advantages for UK businesses:

No hidden FX fees on the payment itself: the card settles in USD, so the supplier receives exactly the invoiced amount
Supplier relationships improve: payment is instant and confirmed, unlike a SWIFT transfer that may take days to appear in the supplier's account
Risk isolation: each supplier gets a separate virtual card with its own limit, reducing exposure if a card number is compromised
Both Visa and Mastercard networks: choose the network based on supplier preferences
Stablecoin funding option: businesses that hold USDC can fund cards directly without converting to GBP first — particularly useful for businesses that also receive revenue in USDC

For UK importers, trading companies, and agencies with multiple US suppliers, the combination of lower FX costs, instant settlement, and per-supplier card management makes PhotonPay a strong fit for recurring B2B payments.

What to Consider When Choosing a USD Payment Method

The right payment method depends less on the headline fee and more on how it fits into your business's actual payment workflow.

FX Transparency and Total Cost

Not all FX fees are disclosed in the same way. Banks quote a spread that is rarely visible on your statement. Specialist platforms show the exchange rate explicitly. When comparing options, calculate the total cost for your typical payment size: for a £5,000 transfer, a 1% difference in FX cost equals £50 per transaction.

Payment Speed and Supplier Relationships

US suppliers are accustomed to domestic payment speeds. A cheque may take days to clear; an ACH transfer may take two business days; a card payment is confirmed instantly. When you pay a US supplier via SWIFT and the payment takes four days to arrive, the supplier may ship late, charge a late fee, or question whether the payment was sent at all.

Paying by USD virtual card eliminates this friction: the supplier's accounts receivable team sees the payment confirmed on the day it is sent. For businesses where supplier reliability directly affects their own customer commitments, payment speed is not a convenience — it is a risk management tool.

Compliance and HMRC Reporting

UK businesses must report all international payments accurately for corporation tax and VAT purposes. The method you use to pay US suppliers affects how easily you can produce audit-ready records.

Frequently Asked Questions

What is the cheapest way to pay US suppliers from the UK?

For occasional payments under £5,000, Wise Business typically offers the lowest total cost. For regular payments to multiple US suppliers, a USD-denominated virtual card — such as those issued by PhotonPay — reduces both FX costs and administrative time, making it more cost-effective at scale.

Do I need a US bank account to pay USD suppliers?

No. US suppliers do not need you to have a US bank account; they only need to receive the invoiced USD amount. A USD virtual card issued by a UK-regulated provider achieves the same result: the supplier receives USD, and you pay from GBP (or USDC) on your end.

How do virtual cards compare to SWIFT for B2B payments?

SWIFT transfers take 2–5 business days and incur multiple fees. Virtual card payments on the Visa or Mastercard networks are confirmed instantly, incur no intermediary bank deductions, and provide a clear transaction record. For B2B supplier payments, virtual cards are faster and typically cheaper for amounts under £50,000.

Can I fund business payment cards with stablecoins?

Yes. PhotonPay allows businesses to fund virtual cards with USDC. The stablecoin balance is held in your multi-currency wallet and allocated to cards as needed. This is particularly useful for businesses that receive revenue in USDC and want to use those funds directly for supplier payments without converting to GBP first.

Conclusion

Paying US suppliers in USD from the UK does not require accepting the high fees and slow settlement of traditional banking. For occasional small payments, platforms like Wise offer a transparent and affordable option. For businesses managing multiple US suppliers and regular payment cycles, a USD-denominated virtual card provides lower total cost, instant settlement, and per-supplier payment control that banking rails cannot match.

PhotonPay helps UK businesses pay US suppliers in USD using multi-currency wallets and virtual cards — with transparent FX, instant settlement, and consolidated transaction records for HMRC-ready reporting.
