What UK businesses should check before paying overseas suppliers

An overseas supplier’s invoice can look straightforward: an amount, a currency and a payment deadline. For a UK business paying from a sterling account, though, the final cost also depends on the exchange rate and any charges involved in getting the money to its destination.

That matters whether you are importing stock, buying equipment or paying a manufacturer’s deposit. A price agreed several weeks ago may cost more in pounds by the time payment is due. Before sending the money, a few checks can help you budget accurately and avoid unnecessary delays.

Confirm the currency and payment terms

Start with the purchase agreement. Check which currency the supplier expects, whether the invoice covers a deposit or the full balance, and when the funds must reach their account.

If a supplier offers a choice between paying in sterling and their local currency, compare the total cost of both options. A sterling invoice makes the amount easier to budget for, but it does not automatically make the purchase cheaper. Ask how the price has been calculated before deciding.

It is also worth checking whether production or dispatch depends on cleared funds. That can make the arrival date more important than the date you authorise the transfer.

Compare the full cost of the transfer

When comparing providers, use the same invoice amount and request quotes close together. A quote from Monday and another from Thursday may reflect different market conditions.

Ask how many pounds you will need to pay for the supplier to receive the exact amount owed. Confirm whether the quote includes all charges and whether any deductions could be made along the way. A transfer advertised without a separate fee still needs to be assessed alongside its exchange rate.

Businesses can include a currency specialist such as Pathfinder FX in that comparison. The firm supports business currency exchange and international payments, with online and telephone dealing. Have the invoice currency, amount and deadline ready so you can discuss the actual payment.

Check the sterling cost before committing

Exchange rate changes can affect the cost of an order even when the supplier’s price stays the same. As an illustration, a €20,000 invoice would cost £16,666.67 at €1.20 to the pound, or £17,391.30 at €1.15, before any fees. That is a difference of £724.63.

These are example rates, but the calculation shows why an old estimate should be checked before you approve a purchase. If you place repeat orders, record the sterling cost each time so changes are visible when reviewing your margins.

Allow time for the money to arrive

Ask your provider for the expected arrival date for that particular currency and destination. Payment routes and cut-off times vary, so avoid assuming every overseas transfer follows the same timetable.

For a first payment, find out what account checks and documents are needed before the invoice becomes urgent. Keep the supplier informed if timing is tight, particularly when a delayed deposit could hold up an order.

Verify the bank details and keep a clear record

Treat an unexpected change of bank details as a reason to pause. Contact the supplier using a telephone number you already trust, rather than one supplied in the message requesting the change. An email that appears to come from a familiar contact is not enough on its own.

Before authorising payment, check the recipient details, currency, amount and invoice reference. Afterwards, keep the invoice, exchange confirmation and payment receipt together, and send the supplier confirmation. This gives both sides a clear record if a payment needs tracing or an invoice is queried later.
