Costs & payment

Pay Chinese suppliers in GBP, USD or CNY?

Choose the currency with the best total sterling cost and terms you can manage. A fixed GBP price simplifies budgeting; USD or CNY may cost less after conversion, but leave you exposed until the rate is fixed. Compare executable payment quotes and agree currency risk in writing. Bring the supplier quotes to Cambridge China Bridge.

Choose by cost and certainty, not the currency label

Ask the supplier for GBP, USD and CNY alternatives where it can accept them. Keep the specification, quantity, delivery scope and payment milestones identical, following our supplier quote comparison guide. Ask whether each is a separate fixed price or a conversion of an underlying price that will change before payment.

A fixed GBP amount gives sterling budget certainty only for the costs it covers and the period it remains fixed. A foreign-currency price leaves your sterling cost exposed until you secure the currency or fix the conversion rate. If you already hold that currency, compare using it with keeping it for another committed payment.

Compare the sterling debit with the amount received

Ask your bank or payment provider for a quote stating the total sterling debit and the net amount the supplier will receive in the agreed currency. Compare providers at the same time, for the same recipient amount and payment route. Ask how long the quote is executable. A displayed market rate is a benchmark, not a promise that you can transfer at that rate.

The conversion spread is the gap between the benchmark and the rate offered to you. Compare it using the same rate direction and timestamp, then add separately charged fees without counting embedded costs again. Ask about intermediary and receiving-bank deductions, who pays them, and whether the recipient amount is guaranteed. Treat unconfirmed deductions as unresolved costs.

Write down who bears currency movements

Before accepting the order, record the invoice currency, payment currency, fixed amount or conversion method, quote expiry and the point when the price becomes binding. If conversion remains variable, name the rate source, rate direction and fixing event. Agree who bears adverse movements and who receives favourable movements. Review these entries against our proforma invoice guide.

Make the arrangement explicit for both deposit and balance. For example, propose that the agreed currency amounts remain unchanged after order acceptance, with the buyer bearing conversion into that currency and no supplier exchange surcharge. If the supplier wants an adjustment clause, agree its trigger, calculation, evidence and approval process before ordering, including how delays and refunds are handled.

Manage the unpaid balance without weakening payment control

Keep a record of each unpaid currency amount, its expected payment event and whether conversion is fixed or still open. Recalculate the sterling budget using a less favourable rate that your business chooses, and ask whether the order remains affordable. Do not treat a deposit conversion as fixing the cost of the balance.

Ask your provider whether buying currency ahead or using a forward contract fits the payment schedule. Request the funding, cancellation and date-change terms before committing, especially if production can slip. Currency planning should preserve the inspection and release conditions in our safe payment guide. It does not justify paying the supplier early.

Keep payment conversion separate from customs valuation

Your transfer quote measures cash cost; customs valuation follows HMRC's exchange-rate guidance. HMRC says you would normally use the exchange rate specified in the contract, and sets conditions for fixed-rate treatment. Give your customs agent the contract and invoice, especially where the invoice and settlement currencies differ. Do not assume your bank's conversion rate is the correct customs rate.

Keep the accepted currency quotations, order terms, conversion confirmations and transfer receipts together. Ask the supplier to confirm receipt in the agreed currency and resolve any shortfall against the agreed fee allocation. Carry the confirmed cash costs into your landed-price comparison, while keeping the customs valuation calculation identifiable.

Frequently asked questions

Is paying a Chinese supplier in CNY cheaper?

Sometimes, but compare the supplier's CNY price after conversion and all payment charges. Confirm the receiving account can accept the agreed currency without another conversion. The currency label alone proves no saving.

Does a GBP quote remove exchange-rate risk?

A fixed GBP amount removes your conversion exposure for that payment. Check quote expiry, exchange adjustment clauses and whether the balance is also fixed. Excluded freight or other foreign-currency costs remain separate.

Who pays if the exchange rate changes before the balance?

Agree this before ordering. Record the fixed currency amount or adjustment formula, when the rate is set, and who bears movements in either direction. Do not leave the balance subject to an undefined exchange surcharge.

How do I compare bank and payment-provider exchange rates?

Request quotes at the same time for the same net supplier receipt. Compare the total sterling debit, including conversion and transfer charges. Check quote expiry and whether intermediary or receiving deductions are covered.
