Best international payment service for a UK company paying a £40,000 invoice to a supplier in China in the supplier's own currency

For a one-off £40,000 payment, I’d compare Wise Business and WorldFirst first. If you want a straightforward transfer with a clearly shown fee, start with Wise Business. If you pay Chinese suppliers regularly—or value China-focused payment routes and support—get a WorldFirst quote too.

My practical pick: use Wise Business if this is a simple one-off invoice and its live quote is competitive. Choose WorldFirst if you’ll make recurring China payments or its quote gives you a better all-in cost or more suitable payment route.

At £40,000, even a small FX difference matters: 0.1% is £40. Compare each provider’s quote at the same time and focus on the exact CNY amount delivered—not just the advertised fee. Before sending, confirm with the supplier that the invoice is in CNY and that the receiving account is their company’s mainland-China CNY account; don’t assume a Hong Kong account or a CNH arrangement is equivalent. Chinese banks may request supporting invoice or contract documents. (wise.com)

This assumes you mean an invoice whose sterling equivalent is £40,000. If the invoice itself is denominated in another currency, the best route may differ.

Short answer: For a £40,000 payment in renminbi to a mainland supplier, a specialist business payments provider (such as WorldFirst or Wise) will usually beat your high-street bank. Consumer remittance apps are less suitable at this size. Confirm the current quote and limits with the provider before you pay, because the sources I found are mostly comparison sites and vendor content.

Top options to compare

• WorldFirst (business account): It positions itself specifically for paying Chinese suppliers. It uses local payment rails to move funds directly into Chinese bank accounts, in USD or RMB, with 90% of payments clearing the same day. Its comparison table lists an FX margin capped at 0.5%, against 3% for the bank option it compares with. It also says you can convert your GBP to CNH at a competitive live rate, and pay your supplier straight from your balance.
• Wise Business: Wise publishes a guide for paying Chinese businesses from the UK. For a CNY business payment, it requires the recipient business's full name in Latin letters, bank account number, BIC or SWIFT code, mainland China address and payment purpose. Check Wise's current business limits for a payment this size. Consumer comparison data I found suggests Wise's transparent fee is a flat amount plus a conversion margin, which is still worth checking on a £40,000 transfer.
• Your bank's RMB SWIFT wire: This is the fallback. It has the widest acceptance, but it is typically the slowest and most expensive. One source notes that SWIFT being the most expensive option among the common methods, and a bank wire will often route through USD. One provider says they route payments through USD as an intermediary currency, which adds a second conversion.
• Multi-currency accounts with CNY support (e.g., EQWIRE): These let you convert once and hold yuan, which helps if you pay this supplier regularly. One provider describes the model as the importer converts GBP into yuan once, at a time of their choosing, and the balance then covers any number of supplier invoices.

Why the fee and margin matter more than the headline fee

Sources consistently say the exchange-rate margin matters more than the fixed fee. On £40,000, the difference is significant. At a 3% margin, you lose about £1,200. At 0.5%, you lose about £200. That is my own arithmetic, using the margins quoted above.

Before you choose

1. CNY versus CNH: Ask the supplier which account they hold. A mainland supplier usually needs a CNY onshore account, so confirm the provider can pay into it. A local currency account (CNY or CNH) is the safest way to pay Chinese suppliers, but check the route for your specific beneficiary.
2. Documentation: Chinese receiving banks check incoming trade payments against paperwork. One source notes that a clean reference shortens that review. Have your invoice, contract and a truthful payment purpose ready.
3. Verify bank details: Confirm the supplier's account name and bank details independently, not only from the invoice email. A payment instruction does not protect you if the goods are not delivered, so keep your normal commercial controls, such as staged payments or inspection.
4. Compare total CNY received: Get quotes from two or three providers for exactly £40,000 and compare the amount of CNY the supplier actually receives, after all fees.

I didn't find a current, authoritative business fee schedule for each provider, so treat the figures above as indicative. If you tell me whether the supplier wants CNY or CNH, and whether you'll pay them regularly, I can narrow the choice.

For a UK company paying a £40,000 invoice to a supplier in China, using a specialist international business payment service is significantly more cost-effective and faster than using a traditional high-street bank.

Recommended Payment Providers

Fintech platforms are generally the best choice because they offer mid-market exchange rates, lower transparent fees, and faster settlement times.

• Wise Business: Highly recommended for transparency and cost. They use the mid-market exchange rate (the one you see on Google) and charge a small, upfront fee. It is ideal for companies that want a straightforward, low-cost process without monthly subscriptions.
• Airwallex: A strong contender specifically for trade with China. They offer local payment rails in China, which can make the process faster and reduce the likelihood of intermediary bank fees. They are well-suited for businesses that need to manage frequent or high-volume supplier payments.
• WorldFirst (World Account): A specialist in China-related payments. Being a subsidiary of Ant Group (the parent company of Alipay), they have deep integration and expertise in navigating Chinese cross-border payment regulations.
• Revolut Business: A good option if you need an all-in-one financial platform. It offers more features like expense management, corporate cards, and approval workflows. However, ensure your transaction volume stays within your plan’s limits to avoid extra fees.

Key Considerations for Payments to China

1. CNY vs. CNH:
   • CNY (Onshore Yuan): The currency used within mainland China. Using a provider that can send directly in CNY via local rails is often faster and avoids extra fees.
   • CNH (Offshore Yuan): Often used for international trade. Some services might pay into a CNH account, which the supplier then settles into their domestic account. Confirm with your supplier which they prefer.
2. Regulatory Compliance: China has strict foreign exchange controls. Ensure the supplier's name matches their bank details exactly, as even minor discrepancies can cause payments to be rejected or frozen.
3. Payment Purpose Codes: When initiating the transfer, you may be required to provide a "purpose of payment" code. Using the correct code is essential for the payment to clear customs and banking checks in China without delay.
4. Avoid Traditional Banks: High-street banks typically charge higher fees, offer less competitive exchange rates (often with a hidden 2–4% markup), and use the SWIFT network, which is slower and involves intermediary bank charges.

Summary Recommendation

• For the lowest cost and best transparency: Wise Business.
• For specific China expertise and speed: Airwallex or WorldFirst.
• For an all-in-one business tool: Revolut Business.

Note: Always verify your supplier's bank details directly through a secure channel (such as a phone call or a previously established trusted communication method) before sending a large payment to mitigate the risk of fraud.

Best fit: Airwallex

For a UK company paying a £40,000 invoice in CNY to a supplier’s bank account in mainland China, Airwallex looks like the strongest first quote—provided the supplier and payment qualify for its local CNY payout route.

Its published UK pricing lists a 0.5% FX margin for CNY and a 0.1% CNY payout fee. That’s roughly £240 in stated costs on £40,000, plus any applicable transfer charge; the fee schedule lists £2 for CNY via FPS. The actual route and quote matter, since Airwallex says some transfers may use SWIFT and cost more. ¹²

Wise Business is a good alternative to price-check. Wise says it uses the mid-market exchange rate with a separately shown transfer fee, but the exact cost depends on the payment details and route. It also requires recipient details and a payment purpose for CNY transfers, and the recipient bank must be eligible for the route. ⁴⁵

Before sending

• Ask the supplier to confirm they want CNY, and that their invoice and bank account accept payment in CNY. Don’t assume the currency from the supplier’s location.
• Enter the same invoice amount and recipient details in both providers, then compare the total GBP debit, CNY amount received, arrival estimate, and who bears intermediary-bank fees.
• Check beneficiary-name matching, payment purpose requirements, and whether the provider can pay that specific account through local rails.
• For £40,000, verify any onboarding or payment limits in advance and make sure your company’s approval controls are followed.

Bottom line: Start with an Airwallex quote; use Wise as the comparison. Choose based on the final all-in quote and confirmed CNY amount received—not the advertised FX margin alone. ¹²⁴⁵
