Stripe, PayPal or Adyen: which payment gateway should you choose? It’s a more strategic decision than it may first appear. Many merchants treat it as a simple fee issue. Yet a gateway directly affects conversion, trust, acceptance rate, risk management, international reach, deployment speed, and sometimes even the technical complexity of the entire stack.
The three players do not tell the same story. Stripe emphasizes a complete platform, highly oriented toward developers and product growth, with clear pricing on the standard offering and a strong API-first approach. PayPal leans more on coverage, consumer trust, ease of adoption, and the massive presence of its wallet. Adyen, meanwhile, positions itself more as a global, unified payment infrastructure, particularly strong for international needs, omnichannel payments, and enterprise use cases.
In this guide, we will compare Stripe, PayPal, and Adyen according to the criteria that really matter: pricing structure, ease of integration, payment methods, international reach, B2B / enterprise, and the real cost beyond the marketing display. The goal is not to declare a universal winner. The goal is to help you choose the right platform for your real-world context.
What you will understand: the real differences between these three gateways beyond the slogans.
What you will be able to do: choose a PSP according to your size, your countries, your team, and your level of complexity.
To connect with: Shopify integration, PayPal conversion and e-commerce analytics.
If you are trying to weigh simplicity, coverage, control, and scalability, this comparison will give you a much more useful framework than a simple feature grid.
Summary
Three gateways, three payment philosophies
The first point to clarify is simple: Stripe, PayPal and Adyen do not play exactly the same role in merchants' minds, nor in the minds of technical teams.
Stripe
Stripe presents itself as an online payment platform designed to support growth. Its pricing page highlights a complete platform, more than a hundred payment methods, optimization through machine learning, preconfigured interface elements, and a very strong API and customization logic.
PayPal
PayPal puts commercial reach, customer choice, and familiarity at the center. Its “Accept payments” page emphasizes its more than 400 million active accounts, the ability to accept PayPal, cards, wallets, and installment payments, as well as a single platform designed for small, medium, and large businesses.
Adyen
Adyen positions itself more as a global payment infrastructure and unified commerce platform. Its pricing page highlights a transaction-based model, with no monthly or setup fees, a single integration for multiple payment methods, flexible settlements in multiple currencies, and an interchange++ logic that is very clear for sophisticated merchants.
Takeaway: Stripe is often chosen for its product flexibility, PayPal for consumer trust, and Adyen for its global infrastructure and enterprise logic.
Fees: why the displayed price never tells the whole story
The classic trap is to compare only the percentage shown on the pricing page. In reality, you need to look at the whole structure: fixed fees, domestic vs international cards, currency conversion, disputes, local payment methods, settlement, and sometimes negotiation depending on volume.
Stripe
Stripe's French page announces on the standard offering 1.5 % + €0.25 for standard EEA cards, 1.9 % + €0.25 for premium EEA cards, 2.5 % + €0.25 for UK cards and 3.25 % + €0.25 for international cards, with + 2 % in the event of currency conversion. Stripe also shows readable prices on other building blocks such as SEPA direct debits, disputes and certain ancillary features. It is clear pricing, fairly comfortable for merchants who want to quickly understand their cost.
PayPal
PayPal takes a more flexible approach on its French business page: no monthly or activation fees, you pay when you get paid, but the fees vary depending on the transaction type. The platform therefore points you to a dedicated pricing table. The advantage is the initial commercial clarity. The drawback is that PayPal is often compared too vaguely if you don't then dig into the specific use cases.
Adyen
Adyen highlights a formula that seems simple at first glance: fixed processing fees + fees related to the payment method. On cards, the logic interchange++ + 0.60 % often appears, to which a fixed processing fee of $0.13 is added in the pricing page example. This structure can be very attractive at scale, but it is less intuitive for a beginner merchant than Stripe's flat-fee logic.
What you really need to compare
The cost of your actual mix: countries, card types, wallets, BNPL, local methods.
The international cost: international cards, FX, settlement.
The cost of disputes and risk.
The technical cost of integration and maintenance.
The gateway that is cheapest “on the sheet” is not necessarily the cheapest in your real operations.
Stripe: the natural choice for teams that want control and rapid integration
Stripe remains very strong with teams that want a unified, programmable platform that is quick to deploy. The French pricing page sums up this logic well: no setup or monthly fees on the standard offering, broad payment method coverage, payment optimization, Link, 3D Secure included in Payments for standard accounts, preconfigured UI elements, and customization logic as volume grows.
What Stripe does particularly well
Developer experience: documentation, APIs, prebuilt elements.
Fast integration for many use cases.
Broad product coverage: cards, wallets, direct debits, payment links, recurring, payouts, etc.
Modular approach: you can start simple and then add complexity.
Stripe is especially well suited for DTC brands, SaaS companies, product teams, or businesses that want to keep control over their checkout experience and payment rules.
Its possible limitations
In some international contexts or very high-volume cases, the flat-fee logic can become less optimal than a model closer to interchange++. And for very multi-entity, omnichannel, or heavily negotiated enterprise organizations, Stripe is not always the obvious only choice.
PayPal: the power of customer trust and the wallet
PayPal remains unique for a simple reason: it is both a PSP and a payment brand that customers recognize immediately. The French business page emphasizes this point with its 400 million active accounts, the promise of “customer choice,” online payment, cards, Pay in 4X, payment links, point of sale, invoicing, as well as coverage in more than 200 markets and 130 currencies.
What PayPal brings in concrete terms
Immediate trust for many buyers.
A powerful wallet that can reassure and speed up the decision.
Simple setup for many SMEs.
Varied options: checkout, payment links, invoices, POS, virtual terminal.
PayPal is often very relevant as an additional payment method to capture customers who specifically want to pay with their PayPal account. In some contexts, it also works as a primary platform, especially for organizations that want to move fast without technical overhead.
Its possible limitations
PayPal is less often chosen as the “programmable backbone” of a sophisticated payment architecture. Its positioning is more commercial and wallet-centric. And depending on the countries, use cases and fee structure, the total cost may be less optimized than an infrastructure designed from the outset for volumes or enterprise negotiation.
Adyen: unified, international infrastructure logic
Adyen speaks mainly to merchants who already have a certain level of maturity. Its pricing page emphasizes a single integration, no monthly or setup fees, flexible settlements, and a very broad catalog of payment methods. But what mainly sets Adyen apart is its global platform logic, with pricing that is closer to the network’s actual costs, notably through interchange++.
Adyen’s strengths
International architecture designed for multiple countries and multiple local payment methods.
Multi-currency settlements and the ability to link several bank accounts.
Unified online + in-store logic that is very attractive for omnichannel businesses.
More granular pricing and potentially more advantageous at high volume.
Adyen becomes particularly relevant when a business sells in several countries, needs to manage many local payment methods, or is looking for a more robust infrastructure for an enterprise environment.
Its possible limitations
For a small organization, Adyen may seem more complex, more “infrastructure-like,” and less intuitive than a solution like Stripe or PayPal. The pricing model is also harder to read for teams that want a simple and immediately understandable rate card.
Checkout, conversion, and acceptance rate: the metric we underestimate
The gateway is not just a matter of fees. It directly affects the ability to get a transaction through. Stripe places a lot of emphasis on payment optimization, Link, machine learning, 3D Secure, Adaptive Acceptance, and other tools designed to improve acceptance and smoothness. PayPal, for its part, relies on the familiarity of its button and the trust in its wallet. Adyen, meanwhile, highlights the depth of its payment orchestration and the ability to connect different payment methods with a single logic.
Why this matters
A cheaper gateway that converts less well can end up costing more overall. Conversely, a slightly more expensive PSP that is more reassuring or better integrated with your market can generate more useful revenue.
Questions to ask
Does the button or wallet reassure my customers?
Is the acceptance rate good in my markets?
Does the redirect or checkout experience add friction?
Does the PSP handle fraud well without blocking too many good payments?
In other words, you need to compare the gateway based on net conversion, not just the unit invoice.
International, multi-currency, local payment methods: where differences become visible
It is often in international markets that the differences become the strongest. Stripe highlights more than a hundred payment methods, currency management, multicurrency transfers, and local solutions such as SEPA direct debit. PayPal emphasizes its presence in more than 200 markets and 130 currencies. Adyen, for its part, structures its proposition directly around the multiplicity of payment methods and flexible settlement in the desired currency.
When it becomes decisive
You sell in several countries.
You need to offer local methods: wallets, BNPL, direct debits, regional options.
You want to avoid unnecessary conversion costs.
You want better control over your settlements and your settlement accounts.
For a very domestic brand, these questions are less decisive. For a European or international brand, they become foundational. This is often where Adyen gains strength, where Stripe remains very consistent, and where PayPal mainly plays the role of a familiar payment method and broad coverage.
Which gateway should you choose based on your profile?
Rather than looking for an outright winner, it is better to think in terms of business profile.
Choose Stripe if…
You want to move fast with an excellent API layer.
You have a product/tech team or a custom integration.
You want a fairly broad payment platform without too much enterprise overhead.
Choose PayPal if…
Customer trust is a key lever.
You want to capture users who explicitly prefer PayPal.
You are looking for easy adoption and broad commercial coverage.
Choose Adyen if…
You are more international, more omnichannel, more complex.
You have volumes that justify a more granular pricing analysis.
You have enterprise or unified online + offline needs.
In many cases, the right answer is not “one or the other”, but a thoughtful combination: a primary PSP for cards and control over the flow, then PayPal as a complementary method to capture strong wallet preference.
The real cost: not just the transaction, but the surrounding stack
The cost of a gateway is never limited to the percentage per transaction. You also need to consider:
The cost of integration and maintenance.
The cost of fraud and disputes.
The cost of redirection or checkout friction if it reduces conversion.
The cost of international operations: currencies, settlement, local payment methods, compliance.
The opportunity cost if your PSP limits what you can build later.
Stripe is often strong on the cost of getting started and product speed. PayPal is strong on trust and adoption. Adyen is strong on global infrastructure logic. But none is “the cheapest” or “the best” in absolute terms outside of context.
The right question is not: which gateway costs the least?
The right question is: which gateway maximizes useful revenue after cost, risk, maintenance, and friction?
And what about Shopify in all this?
For many e-commerce merchants, especially on Shopify, the gateway is not an isolated layer. It fits into checkout, apps, conversion rules, support, and sometimes assisted sales journeys. The choice of PSP can therefore have concrete effects on site fluidity and on the experience you manage to build.
This is particularly true if you want to:
Connect your payment to your Shopify stack.
Display the right payment methods depending on the customer.
Reduce friction at checkout.
Improve conversion while keeping control.
This is also where product, support, and conversion strategy meet the payments topic. The gateway is part of the commercial engine, not just the financial layer.
Qstomy: useful when payment, trust, and the sales objection come together
Payment is not only an infrastructure issue. It is also a moment of hesitation, objection, and sometimes abandonment. Some customers wonder whether the payment method is reliable, whether they can pay in installments, whether support is available if there is a problem, or which option best suits their situation.
Qstomy can help at this layer by responding more quickly to sales and support questions that come before the payment itself. The goal is not to replace the PSP. The goal is to help the customer get to payment with less uncertainty.
For Shopify: see the Shopify integration.
For sales: see the Sales page.
For support: see the Customer Support page.
For a demo: request a demo.
When objections around payment, checkout, or trust are resolved more quickly, the chosen gateway can do its job better: collecting payment without unnecessary friction.
In short, sources and FAQ
In brief
Stripe, PayPal, and Adyen serve different purposes. Stripe is very strong in product flexibility, upfront pricing clarity, and modern integration. PayPal remains extremely powerful for customer trust, the wallet, and ease of adoption. Adyen becomes especially compelling for more international, more complex, or more enterprise merchants. The right choice therefore does not depend on an advertised rate or a general reputation, but on your actual payment structure, your geography, and your level of complexity.
Stripe : API, speed, broad platform.
PayPal : customer trust, wallet, coverage.
Adyen : global infrastructure, international, enterprise.
True criterion : net useful revenue after cost, friction, and risk.
Best practice : compare on your real mix, not on an abstract grid.

FAQ
Which payment gateway is the easiest to integrate?
In many cases, Stripe is the easiest to integrate cleanly for a product team or a modern integration. PayPal is also easy to add in many contexts, especially as a complementary method.
Is Stripe cheaper than PayPal?
Not always. It all depends on your payment mix, your countries, the cards used, currency conversions, disputes, and your volume. You need to compare using your actual transactions.
When does Adyen become more relevant?
Adyen becomes especially compelling for more international, omnichannel, or enterprise merchants, especially when pricing granularity, multi-currency settlements, and local payment methods become strategic.
Should you choose a single PSP?
Not necessarily. Many merchants use a primary PSP for cards and a complementary method like PayPal to capture a very strong customer preference.
Does the gateway influence conversion?
Yes. It influences trust, checkout flow, authorization rate, and risk management. So it is as much a commercial topic as a financial one.
What is the right decision criterion?
The right criterion is net useful revenue after costs, friction, risk, and maintenance, not just the percentage shown on the pricing page.
