Choose a payment provider by matching its country eligibility, payment methods and operating terms to where your business is registered and where your customers pay from. There is no universal cheapest or best option: compare providers using the same transaction assumptions, then confirm current country-specific fees and terms directly before signing up.
Start with your business and customer markets
First identify the country where your business is established and the countries where you expect customers. Provider eligibility, available payment methods and pricing can vary by merchant location and customer market. Check that the provider accepts businesses in your country and supports the markets you plan to serve before comparing rates.
Write down the practical requirements that will shape your shortlist:
- Business details: registration country, product category, expected sales volume and average transaction value.
- Customer markets: countries served, likely card origins and locally important payment methods.
- How customers pay: one-off purchases, subscriptions or recurring billing; whether you also need in-person payments or marketplace and split-payment functionality.
- Money movement: currencies to accept and receive, preferred settlement currency and payout timing.
- Technology: website platform, available developer resources, reporting and reconciliation needs.
These details help prevent a misleading comparison based on a rate that applies to another country or payment method.

Compare the full cost for your payment mix
A headline card rate is only one part of the cost. Include percentage and fixed transaction charges, fees for alternative payment methods, currency conversion, cross-border transactions, refunds, disputes, payouts, monthly or minimum charges, and separately priced services. For example, Adyen describes its pricing as a fixed processing fee plus a payment-method fee; it says its stated pay-per-transaction model has no setup or monthly fee, while other products may be priced separately (Adyen pricing).
Build one like-for-like scenario for every provider. Use your estimated monthly transaction count and value, average ticket, card origins and types, expected use of local payment methods, refund and dispute rates, and currency needs. Ask each provider to price that same scenario and clarify which charges are recurring, conditional or separate. Without a business-specific profile and current schedules, a general annual-savings estimate would not be meaningful.
Displayed prices are country- and method-specific snapshots, not a Europe-wide tariff. Mollie’s official pricing pages, for instance, present charges by country and payment method and state that payment is charged for successful transactions. Select the page for your actual merchant country and the methods you intend to offer; check the live schedule before relying on a figure (Mollie Belgium pricing; Mollie France pricing). PayPal also publishes separate merchant fee schedules for individual markets. Its Ireland and Liechtenstein schedules label an update date of 7 September 2026, but rates differ by payment and account market; do not carry one country’s fee into another (PayPal Ireland merchant fees; PayPal Liechtenstein merchant fees).

Check payment methods and market coverage
For each target country, ask whether the provider supports the cards, bank-based methods and wallets your customers are likely to use. Confirm the methods are available to a merchant established in your country, not merely to customers in the market. Also check whether the provider supports recurring payments or marketplace flows if your business needs them. A pricing page for one country or method does not establish coverage everywhere.
Payment-method choice also interacts with legal requirements. European Commission guidance explains that, under stated conditions, a business accepting a specified electronic payment method and currency may not reject it solely because a customer or the customer’s payment service provider is located elsewhere in the EU. That is not a general requirement to offer every payment method; see the Commission’s guidance for the conditions and scope (Your Europe: electronic payments).
Make SCA part of the checkout evaluation
Strong customer authentication (SCA) is part of the EU’s PSD2 framework. Article 97 of Directive (EU) 2015/2366 sets authentication requirements for specified cases, including a payer accessing a payment account online, initiating an electronic payment, or taking certain remote actions that may imply fraud or abuse risk. For remote electronic payments, authentication is to be dynamically linked to the specific amount and payee (Directive (EU) 2015/2366, Article 97).

This does not mean every online payment always triggers a new two-factor challenge: the applicable rules include conditions and exemptions. The European Commission says online businesses must be able to perform SCA. Ask how each provider supports authentication flows and applicable exemptions, and test the checkout experience. Using a provider does not remove the merchant’s responsibility to understand and meet its obligations (Your Europe: electronic payments).
The Commission describes PSD2 as part of the EU electronic-payments framework and records political agreement on proposals revising the directive on 27 November 2025. Political agreement on proposals is not, by itself, an enacted replacement rule. Check applicable requirements for your business rather than assuming that proposed changes have already taken effect (European Commission: review of payment services).

Once a provider passes your market and payment-method checks, compare the parts of the service that affect daily operations. These details depend on your business and need to be verified with each provider; the available official materials do not establish a uniform cross-provider scorecard.

Adyen, Mollie and PayPal publish official materials relevant to provider selection, but their prices and coverage must be checked against your specific merchant country and use case. Stripe is also a provider worth investigating; do not infer its current price or specific features without checking its official country and pricing information directly. The available evidence does not support a Europe-wide ranking or a claim that one provider is cheapest.
Do not treat survey mentions as market share or a measure of service quality. Worldline’s 2024 survey of Swiss online retailers reported provider mentions of 32% for PayPal, 13% for Stripe, 4% for Adyen and 2.0% for Mollie. Those figures describe mentions among that survey’s respondents, not the European market as a whole or a current provider ranking (Worldline 2024 Swiss online-retailer survey).

Understand card-fee and fraud claims in context
The European Commission says PSD2 together with the Interchange Fee Regulation limits fees for consumer debit and credit card transactions and bans retailers from imposing surcharges for those card types. The statement has a defined scope and exceptions; it should not be generalized to every card or payment method. Consult the Commission’s explanation for the applicable conditions (Your Europe: electronic payments).
The Commission’s 2023 PSD2 review factsheet reported an almost 50% decrease in the average value of fraudulent transactions across the EU from 2020 to 2021 for card payment service providers. This is a historical, scoped measure; it does not compare provider performance or show that SCA alone caused the decrease (European Commission 2023 PSD2 review factsheet).
