Notes
The comparison includes six buy now, pay later services. Jousto no longer sells: its invoice and instalment service has been discontinued, so it was not scored.
Points are calculated only from figures found on the companies' own websites. Walley and Riverty do not publish prices or terms on their Finnish-language consumer pages, so their missing data are left blank and nothing is guessed for them.
The effective annual interest rates of instalment payments are stated with different examples (Klarna fixed 17.50%, OP for a 1,000 euro credit for 36 months, Svea for a 1,000 euro credit for 12 months), so the figures are indicative.
About this comparison
At an online shop's checkout, invoice and instalment payment look free, but the real costs accumulate from invoicing fees, credit interest and collection fees. We scored 6 buy now, pay later services on 19 metrics. The most important question: are all costs publicly visible before you choose the payment method, or only when the invoice arrives?
Buy now, pay later means an invoice or instalment payment chosen at an online shop's checkout, with which you get the goods immediately and pay later. In the comparison we measured how openly the service tells the consumer the real costs before choosing the payment method: is the invoicing fee visible in euros, how long is the interest-free payment period, what is the credit interest rate of the instalment payment, are the costs of payment reminders and collection stated, and who grants the credit. We do not measure the size of the credit granted or the reasonableness of collection, but the transparency of the public pages.
What transparency means in this category
Invoicing or payment method surcharge displayed in euros (25), interest-free payment period (in days) stated (20), effective annual interest rate of an instalment payment or credit interest displayed (20), payment reminder and collection costs stated (15), lender or business ID (Y-tunnus) displayed (10), Finnish-language contract terms and support (10)
How to read the comparison correctly: Half of the points come from buyer's questions, i.e. things the buyer finds out before deciding. The other half measures how openly the company publishes its prices, terms and contact details. Clear differences in points indicate a genuine difference: one tells you the price immediately, another only after logging in. Close scores should not be read as a ranking order, because every measurement has a margin of variation. The measurement accuracy and the full calculation formula are open in the methodology.
Customer experience is brought into the assessment separately. We also collect customer feedback and customer experiences about companies through separate surveys. The survey results will be added to the overall assessment later.
Regulation tightens in 2026. The EU's new Consumer Credit Directive brings buy now, pay later services and loans under 200 euros under the same supervision as traditional credit for the first time. In Finland the new rules apply to distance selling from 19 June 2026 and in other respects from 20 November 2026. In practice, transparency requirements are tightening: costs and the lender must be stated more clearly already at checkout.
An interest-free invoice is not free. Almost every service gives an interest-free payment period (typically 14–45 days) but adds a fixed invoicing fee to the invoice, most often 2.90–3.00 euros per invoice. When moving to instalment payments, credit interest comes in, in this comparison around 18.5–20 percent, and often a monthly account management fee. The cheapest way is to pay the whole invoice at once by the due date.
Some of the services are foreign banks. Klarna (Sweden) and Walley, i.e. Norion Bank (Sweden), operate in Finland under a Swedish banking licence, whereas Jousto (Aurajoki Nordic Oy), Riverty Finland, OP Lasku (OP Yrityspankki) and Svea (Svea Payments) are Finnish operators with a business ID (Y-tunnus). We measure the transparency of public pages, not the granting of credit or the reasonableness of collection.
Comparison guide
What to consider in the comparison
Regulation tightens in 2026. The EU's new Consumer Credit Directive brings buy now, pay later services and loans under 200 euros under the same supervision as traditional credit for the first time. In Finland the new rules apply to distance selling from 19 June 2026 and in other respects from 20 November 2026. In practice, costs and the lender must be stated more clearly than before already at checkout.
An interest-free invoice is not free. Almost every service gives an interest-free payment period, but adds a fixed invoicing fee or account management fee to the invoice. For example, at Jousto the invoicing fee is 2.90 euros and at OP Lasku the account management fee is 2.95 euros. The cheapest way is to pay the whole invoice in one go by the due date.
The interest-free payment period varies by service. With Svea's invoice the payment period is at least 14 days, with Jousto 30 days and with OP Lasku up to 45 days. A longer interest-free payment period gives more leeway to pay the invoice without extra costs.
Switching to instalments brings interest. When you convert an invoice into instalments, credit interest and often a monthly account management fee are added. In this comparison, the credit interest on Jousto's instalment plan is 19.90 per cent and OP Lasku's total interest rate 17.50 per cent. OP also gives an example of the effective annual rate, which for a 1000 euro credit is 24.2 per cent when the account management fee is included.
Some of the services are foreign banks. Klarna and Walley, i.e. Norion Bank, operate in Finland through a Swedish banking licence, whereas Jousto, Riverty, OP Lasku and Svea are Finnish operators with a Finnish business ID (Y-tunnus). Many foreign services show the euro costs only at the shop's checkout or in the app, not on public pages.
How Suomen Paras assesses and scores
Every company is measured with the same public formula: half of the points come from buyer's questions and half from basic metrics, which have four pillars: technical quality, transparency, reachability and AI quality score. Ranking cannot be bought, and you can see the origin of each point on the company's profile. Read the full methodology →
Expert tips
Pay the invoice in full by the due date if you can. Then you only pay the fixed invoicing fee or account management fee and no credit interest at all.
Check the credit interest rate before you convert an invoice into instalments. The annual interest rate of instalment payment in this comparison is around 17-20%, and a long payment period clearly increases the total cost.
Look for the effective annual interest rate. It shows the total cost of the loan including interest and all fees, and is the best figure for comparing different instalment plans.
Remember that an invoice is credit. An unpaid invoice leads to a payment reminder, late-payment interest and eventually debt collection. Only buy as much as you can pay back on time.
Check who grants the credit. The lender's name and business ID (Y-tunnus) or supervising authority tell you who you are contracting with and to whom to complain if something goes wrong.
Frequently asked questions
What does buy now, pay later mean?
It is a payment method selected at an online shop's checkout where you get the product immediately and pay for it later, either in one go by invoice or in parts by instalment payment. An invoice is always credit, and a fixed invoicing fee or account management fee is usually added to it.
Is the invoice free of charge if I pay on time?
An interest-free payment period means that no credit interest on the instalment is charged if you pay the invoice in full by the due date. A fixed invoicing fee or account management fee, in this comparison usually 2.90-2.95 euros per invoice, is still charged. Only paying the full amount at once avoids credit interest.
How much does an instalment cost?
With instalment payment, credit interest and often a monthly account management fee are added to the invoice. In this comparison the credit interest is around 17-20 percent, and when all fees are included, the effective annual interest rate can rise above 24 percent. The longer the payment period, the more interest you pay.
What happens if I do not pay the invoice on time?
A payment reminder is sent for an overdue invoice, with a reminder fee added, and default interest in accordance with the Interest Act accrues on the unpaid amount. If the invoice remains unpaid, it is passed to collection, which causes further costs. A payment default entry may make it harder to obtain credit later.
Will the 2026 regulation change 'buy now, pay later' services?
Yes. The EU's new Consumer Credit Directive brings BNPL services and credits under 200 euros under the same supervision as other credit. In Finland the rules apply to distance selling from 19 June 2026 and in other respects from 20 November 2026. Costs, the lender and the assessment of ability to pay must be disclosed in more detail than before.
