AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Many Nigerian online shops take payment through gateways such as Paystack, which lists international card transactions and says international cards are charged and settled in naira by default. Your UK card is then charged in naira and your bank converts it to pounds, usually at the Visa or Mastercard rate, and may add a non-sterling fee that MoneyHelper says is often around 3%. Whether a given shop accepts foreign cards at all is the merchant's set-up, not yours.
Buying from a Nigerian store while living in the UK should be simple: you have a card, they have a checkout. In practice, Nigerians in the UK report three outcomes. The payment goes through and costs a little more than expected, it is declined, or the shop asks you to pay by bank transfer instead. Each outcome has a reason, and knowing the reason saves you repeated failed attempts and the fraud flags they can trigger.
Does a Nigerian checkout accept a UK card?
Most Nigerian online shops do not process cards themselves. They use a payment gateway. Paystack's pricing page lists a separate line for international card transactions and says merchants can get paid by customers worldwide, so foreign cards are technically supported on that gateway. The page does not say whether every merchant has international payments switched on, and in practice that is a setting on the merchant's side.
- Shop has international cards enabled: your UK Visa or Mastercard can go through, usually after a 3-D Secure check in your banking app.
- Shop takes local cards only: the payment is declined before your bank sees it, or the checkout offers only Nigerian cards, bank transfer or USSD.
- Your bank blocks it: a first payment to a new overseas merchant can be stopped by your bank's fraud checks. Approve it in your app or call the bank, then try once more rather than several times in a row.
Merchants also pay more to accept your card. Paystack lists international transactions at 3.9% plus ₦100, against 1.5% plus ₦100 for local ones, with local fees capped at ₦2,000 (Paystack pricing page, Oct 2026). That is the shop's cost, not yours, but it explains why some small sellers prefer you to pay by transfer.
What currency are you charged in?
Paystack states that international cards are charged and settled in naira by default. So the shop asks for naira, and the conversion to pounds happens at your card issuer. MoneyHelper's guide to debit cards says banks usually use the Visa or Mastercard exchange rate and may add a currency exchange fee, often around 3% of the transaction amount, plus in some cases a fee each time you use the card. Some UK cards charge nothing for spending in foreign currency; your account's tariff says which.
Worked example
Example only, with an assumed rate. You order goods priced at ₦150,000. Assume the card scheme rate that day works out at ₦2,000 to £1, and your card adds a 3% non-sterling fee.
| Line | Amount |
|---|---|
| Order in naira | ₦150,000 |
| Converted at assumed ₦2,000 per £1 | £75.00 |
| Non-sterling fee at 3% (assumed) | £2.25 |
| Total on your UK statement | £77.25 |
On a card with no foreign spending fee the same order would cost £75.00 at that rate. If the order is refunded later, the refund is converted again at the rate on the refund day, so you may get back slightly more or less than you paid.
Debit or credit card?
For buying goods, both work where the shop accepts them. MoneyHelper notes that debit card payments are covered by chargeback: you ask the company first, and your bank can raise a claim, usually within 120 days. Credit cards can add further protection on larger purchases. If the item never arrives, keep the order confirmation, the seller's messages and your statement line; these are what your bank will ask for.
Avoid paying for a 'deposit' or 'reservation' through a card link sent by a stranger on social media. A card payment to a gateway proves you paid the merchant account behind it, not that the seller is real.
When paying by transfer makes more sense
Many Nigerian sellers, especially smaller ones on Instagram or WhatsApp, prefer a naira bank transfer. That needs a naira balance in Nigeria. If you already keep naira for family costs, paying from it avoids the card conversion and the non-sterling fee, though you have paid a conversion cost when you first changed pounds into naira. Our guide to checking the real exchange rate before converting shows how to compare that cost, and why the rate you get differs from the headline explains the margin.
What to check first
- Does the checkout show a foreign-card option, or only Nigerian cards, transfer and USSD?
- What does your UK card charge for non-sterling spending? Check the tariff or app.
- Is your banking app ready to approve a 3-D Secure request?
- Is the seller a registered business with a real address and returns policy?
- Would a naira transfer from money you already hold in Nigeria cost less overall?
Where Pryme fits
A Pryme account holds naira, pounds, dollars and euros together, and Pryme accounts can be opened from the UK. If you keep a naira balance, you can pay a Nigerian shop by local transfer instead of a card. When you need naira, Swap shows the rate and the fee before you approve. Outside Nigeria, Pryme's services are provided through regulated partners.
Questions people ask
Why was my UK card declined on a Nigerian website?
Usually because the shop's payment gateway accepts only Nigerian cards, or because your bank's fraud checks stopped a first payment to an overseas merchant. Check whether the checkout offers a foreign-card option, approve the payment in your banking app, and try once more.
Will I be charged in naira or pounds?
Paystack says international cards are charged and settled in naira by default, so the shop charges naira and your card issuer converts it to pounds on your statement.
How much extra does my UK bank charge?
It depends on the card. MoneyHelper says banks may add a currency exchange fee often around 3% of the transaction, and some cards charge nothing. Your card's tariff gives the figure.
Can I get my money back if a Nigerian seller doesn't deliver?
Ask the seller first, then your bank. MoneyHelper says debit card payments are covered by chargeback, which your bank can usually raise within 120 days. Keep the order, messages and statement line.
