The payment methods for online sales in Finland, in short
A Finnish consumer store is expected to carry four families of payment. Online bank payment through the major Finnish banks, cards, a mobile wallet, and some form of invoice or instalment.
Paytrail, one of the facilitators most Finnish stores use, lists the following on its own payment methods page (checked 20 September 2026). Banks: Nordea, Osuuspankki, Danske Bank, Säästöpankki, Oma Säästöpankki, POP Pankki, Aktia, Ålandsbanken and S-Pankki. Cards: Visa, Mastercard and American Express. Mobile: Apple Pay, Google Pay, MobilePay and Siirto. Invoice and instalment: Klarna, OP Tililuotto, OP Lasku, Walley and Walley B2B invoice.
That list is the shape of the expectation. The rest of this article is about which parts actually matter for your store and what carrying them does to your margin.
Bank buttons and why they matter here
Bank buttons are the habit. A Finnish shopper clicks their own bank, confirms with the app they already use for everything else, and the money moves immediately. There is no card number to type and no three digit code to hunt for on the back of a card.
The reason they matter more here than in most of Europe is trust rather than speed. The bank is a familiar institution standing between the customer and a shop they have never bought from before. For a small store with no brand recognition, that borrowed trust is the most valuable thing on the checkout page.
They also settle cleanly. A bank payment is not a card authorisation that might be reversed weeks later by somebody else's dispute process, which matters when your margin on the order was thin to begin with.
Which banks a Finnish shopper expects to see
Nordea, OP and S-Pankki between them cover a very large share of Finnish retail customers, and a checkout missing any of the three looks unfinished. Danske Bank, Aktia, Säästöpankki, POP Pankki, Oma Säästöpankki and Ålandsbanken fill out the row.
You rarely choose these one at a time. A facilitator gives you the whole set under one contract, which is one of the main reasons small stores use one instead of negotiating separately.
Keep Ålandsbanken even though the customer numbers are modest. Leaving it out reads as a store that has not thought about Åland at all, and Åland customers notice that sort of thing.
MobilePay, cards and invoice
MobilePay is the mobile wallet that matters in Finland. Its own site states that the service is operated by Vipps MobilePay AS, Suomen sivuliike, that customers can pay over 50,000 businesses in store and online, and an announcement dated 12 August 2026 puts the Finnish user count above three million (mobilepay.fi, checked 20 September 2026).
Cards carry the customers who are not in Finland and the ones paying on a company card. Visa and Mastercard are the baseline. American Express is optional and shows up mainly with business travellers and some corporate buyers.
Invoice and instalment is the one small stores argue about. Klarna, Walley and the OP invoice products let a customer receive the goods and pay afterwards, which lifts the average order value on higher priced items and brings in a segment you otherwise never see. The provider carries the credit risk, and that is what the fee buys.
Siirto, Apple Pay and Google Pay
Siirto is a Finnish account to account service that appears in facilitator line ups, Paytrail's among them. It takes a smaller share of checkouts than the bank buttons and usually costs nothing extra to leave enabled.
Apple Pay and Google Pay earn their place for one reason. On a phone they turn a card payment into a fingerprint, and a phone is where most browsing happens. The customer never types a card number, so the usual mobile checkout collapse does not happen.
None of these three changes your year on its own. Together they remove friction on the device where friction costs the most.
What each one costs you
We do not publish other companies' pricing, because it changes and because every contract is negotiated. What is stable, and worth knowing, is the shape of the cost.
Bank payments are usually charged as a fixed amount per transaction, which makes them cheap on a large basket and proportionally expensive on a small one. Cards are usually a percentage plus a small fixed fee, so they behave the opposite way. Invoice and instalment are the most expensive per transaction, because somebody is buying your credit risk.
On top of the per transaction cost there is often a monthly service fee and sometimes a setup fee. Ask each provider for a total against your own basket profile, meaning your real average order value and your real monthly volume, and compare those totals rather than the headline rates. The wider version of that arithmetic is in the online store costs that eat your margin.
Facilitator or direct contracts with each bank
For almost every small and mid sized Finnish store, a facilitator. One contract, one integration, one settlement, one reconciliation file your accountant can read, and the whole set of bank buttons working on the first day.
Direct contracts with each bank start to make sense at volume, where a fraction of a percentage point across thousands of transactions a month exceeds the cost of running several relationships and several integrations. That is a decision for a finance person with a spreadsheet, not a default setting.
The middle ground catches people out. Signing with a facilitator and separately with a card acquirer means two settlement schedules, two reports and two support numbers, and your bookkeeper will find out before you do.
What happens if one is missing
The customer leaves and you never learn why. Checkout abandonment does not come with a reason code, and a missing payment method looks identical in your analytics to a delivery charge that was too high.
The case we meet most often is a foreign company selling into Finland with cards only. The store works perfectly, the traffic arrives, and conversion sits at a fraction of what the same store manages in its home market. Adding bank payment is usually the single largest improvement available to it.
The second case is a Finnish store that dropped invoice payment to save on fees and then watched the average order value fall on its expensive products. The saving was real. The lost orders were bigger.
The checkout page matters more than the logos
A row of payment logos cannot rescue a checkout that asks a private customer for a company name or hides the delivery cost until the final step. Choosing a method is one decision among several, and the others are entirely yours to get right.
Show the total with delivery before you ask for payment. Let people buy without creating an account. Keep the form to the fields you genuinely need, and let the postcode fill in the town.
Put the payment logos somewhere earlier than the checkout as well, on the product page or in the basket. They work as reassurance long before they work as a choice.
Refunds go back the way the money came
Plan refunds as a process rather than as an exception. A bank payment does not reverse itself, and the refund happens in your payment provider's interface, which means somebody in your business needs access to it and a routine for using it.
The Finnish Competition and Consumer Authority is clear that the seller must return the payments received without delay and at the latest 14 days from receiving the customer's notice of withdrawal (kkv.fi, checked 20 September 2026). That clock runs whether or not your week is busy.
Partial refunds are what break processes. A customer returning one item out of three needs the delivery cost handled correctly, and getting it wrong generates more support work than the refund itself ever would.
Business customers want an invoice
If you sell to companies, a card field is not enough. Finnish businesses expect to be invoiced, increasingly as an e-invoice, and a purchasing manager with a budget will often simply not buy from a store that demands a card number.
The options are a business invoice product from your facilitator, such as the Walley B2B invoice that appears in Paytrail's list, or your own invoicing with a credit check behind it. The first is faster to start and the second is cheaper at volume.
Either way, collect the business ID at checkout and validate it. It is the small field that makes the rest of the process work, from the invoice to the accounting entry.
Strong authentication and the basket that dies
Every card payment from a European customer passes through strong customer authentication, which in practice means a push notification from their bank app. That step is where a meaningful share of mobile baskets die, because the customer switches app, gets distracted and never comes back.
You cannot remove the step. You can make the return trip painless by keeping the basket alive, not logging the customer out, and sending one reminder an hour later that returns them to a filled basket instead of the front page.
Bank payments and MobilePay involve the same app switch, and the same fix applies to both.
The customer who is not in Finland
Price in euros, ship where you can genuinely ship, and say on the page which countries those are. A Swedish or Estonian customer who reaches the delivery step and finds their country missing is a wasted visit and a mildly irritated person.
Cards carry most foreign consumer payments, and the larger facilitators will pass through common European methods on request. Resist supporting everything. Two or three neighbouring markets done properly is a strategy. Twenty half supported ones is a support queue.
Check your VAT treatment before switching cross border sales on, because the rules differ from domestic sales and the thresholds are specific to the situation.
A short check before launch
Buy something from your own store with every method you offer, on a phone, using a real card and a real bank account. Then refund it. The number of stores that launch without anyone doing this is higher than you would believe.
Check that the order confirmation arrives, that it names the payment method, and that your accounting sees the transaction with a reference you can match back to the order number.
Then read the consumer side of the rules, because payment, delivery and withdrawal are treated as one process by the authorities even when they are three different suppliers to you. That summary is in consumer rules every Finnish webshop has to follow, and if the store itself is still at the planning stage, begin with what starting an online store in Finland takes.
