Stripe vs PayPal: Which Payment Gateway to Choose for B2B E-commerce in 2026
Operational comparison between Stripe and PayPal for companies selling online to business customers: fees, countries, currencies, protections, disputes, cost calculation, and real use scenarios.
Stripe tends to be chosen as the primary payment infrastructure. PayPal tends to be chosen for the role of a payment method recognized by the end customer. These are prevailing roles, not exclusive characteristics: both offer APIs and merchant features.
Stripe and PayPal are often compared as if they were two versions of the same product. In reality, they tend to occupy different roles in the payment architecture and can coexist within the same company.
Stripe tends to be chosen as a payment infrastructure integrated via API: customizable checkout, recurring billing, subscription management, split payments, payouts, and fraud tools. It also directly supports several payment methods (cards, digital wallets, SEPA transfers, local methods).
PayPal tends to be chosen for the role of a payment method recognized by the end customer: the brand acts as a trust guarantee and simplifies adoption in contexts where the buyer does not know the seller. It also offers APIs, Braintree, and advanced merchant tools, but its prevailing role alongside Stripe tends to be that of an additional payment method.
This guide analyzes both operationally, with verifiable data, a cost calculation based on a B2B scenario, and a comparison table to help you decide with criteria.

It is not a “gateway” choice: it is a choice of prevailing role
Stripe and PayPal are often treated as equivalent alternatives. In reality, they tend to occupy two different roles in the payment flow and can be used together.
Primary infrastructure
Where the company controls the checkout, manages subscriptions, billing, and accounting reconciliation programmatically.
Additional payment method
Where the end customer chooses how to pay and the provider’s brand acts as a trust guarantee.
Context
The choice depends on the business model, the margin per transaction, and the team’s technical inclination. These are prevailing roles, not exclusive.
If you need a payment infrastructure integrated with APIs, recurring billing, and checkout control, Stripe tends to be the most consistent role. If you need a payment method recognized by the end customer and quickly activatable, PayPal tends to be more efficient. These are prevailing roles, not exclusive: both offer APIs and merchant features.
Stripe: operational profile as payment infrastructure
Stripe is a payment platform that allows companies to accept online and in-person payments, manage subscriptions, billing, and payouts. It is designed to be integrated via API into websites, apps, and SaaS platforms. It also directly supports several payment methods (cards, digital wallets, SEPA transfers, local methods).
Operations and checkout
Stripe offers a customizable checkout and pre-built UI components (Stripe Elements) that can be integrated into platforms like Shopify, WooCommerce, Magento, and custom applications. It supports card payments, digital wallets, SEPA transfers, and other regional methods depending on the country.
The standard fee for card transactions in Europe is 1.5% + €0.25 for European cards and 2.5% + €0.25 for non-EU cards (source: stripe.com/pricing, updated September 2026). Conditions may vary by country and account type. Always verify the official pricing.
International fees and currency conversion
Stripe applies a currency conversion fee when the transaction occurs in a currency different from the account’s. The standard fee is 1% on the conversion (source: stripe.com/pricing). Payout fees to foreign bank accounts may vary depending on the destination country.
Protections and fraud tools
Stripe Radar is the included fraud system that uses machine learning to detect suspicious transactions. Stripe is PCI DSS Level 1 compliant. Dispute management takes place through a dashboard with documentary evidence upload and defined timelines.
Recommended usage profile
Stripe tends to be the most consistent choice for B2B SaaS with recurring revenue, marketplaces, platforms with custom checkout, companies with an internal technical team, and business models that require automatic billing and control over the payment flow.
Stripe
Payment infrastructure for B2B e-commerce. Customizable checkout, API, subscriptions, and fraud tools included.
If your business model requires custom checkout, recurring billing, multi-currency management, and programmatic control of the payment flow, Stripe is designed for this role. It is not the fastest choice to activate, but it is the one that offers the greatest operational control in the medium term.
PayPal: operational profile as a recognized payment method
PayPal is a globally recognized payment method that allows companies to accept online and in-person payments. It is used by hundreds of millions of active accounts worldwide and acts as an intermediary between buyer and seller. It also offers APIs, Braintree, and advanced merchant tools.
Operations and checkout
PayPal offers ready integrations for major e-commerce platforms (Shopify, WooCommerce, BigCommerce, Magento) and payment buttons that can be activated without technical development. It supports card payments, PayPal balance, and in some markets installment payments.
The standard fee for commercial transactions in Italy is 3.49% + €0.49 for domestic payments (source: paypal.com/it/webapps/mpp/merchant-fees, updated September 2026). The fee may vary based on monthly volume and country. Always verify the official pricing.
International fees and currency conversion
PayPal applies an additional fee for international transactions and a currency conversion fee. Conditions vary by country and account type. The applied exchange rate includes a spread compared to the market rate: verify the effective rate in your dashboard before operating in a currency other than the euro.
Protections and fraud tools
PayPal is PCI DSS compliant and offers buyer protection and seller protection on eligible transactions. It manages disputes through a structured process with documentary evidence collection. PayPal may apply holds or temporary fund limitations in cases of compliance checks, abnormal volumes, or suspicious activity: this is documented behavior that should be considered in operational planning.
Recommended usage profile
PayPal tends to be the most consistent choice for companies that want to activate payments quickly, for end customers who recognize the brand as a trust guarantee, for small merchants who do not have an internal technical team, and for contexts where integration simplicity prevails over programmatic flow control. It also offers APIs for more advanced integrations, while maintaining a prevailing role as an additional payment method.
PayPal
Globally recognized payment method. Quick activation, simple integration, end-customer trust.
If your end customers prefer paying with PayPal or if you need to activate payments quickly without technical development, PayPal is the most direct tool. The brand acts as a trust guarantee, but control over the payment flow is lower than with an infrastructure like Stripe. A possible configuration is to use the two together to broaden payment method coverage.
Which gateway for which operational need
This is not a ranking. It is a matrix to help you orient yourself based on the prevailing role each gateway should play in your payment architecture.
| Operational need | Role in the system | Most consistent tool | Why |
|---|---|---|---|
| SaaS with recurring subscriptions | Billing infrastructure | Stripe | Native Stripe Billing, plan and upgrade management |
| Quick checkout without development | Payment method | PayPal | Ready buttons, immediate integration |
| Marketplace with split payments | Payment infrastructure | Stripe | Stripe Connect, multi-party payouts |
| End customers who prefer PayPal | Payment method | PayPal | Recognized brand, trust guarantee |
| High volumes with reduced margins | Cost optimization | Stripe | Lower fees on international cards |
| Selling to SMEs in multiple countries | Payment method coverage | Stripe + PayPal | Stripe for cards, PayPal for those who prefer it |
If you are looking for an “absolute winner”, you are probably looking at the problem from the wrong angle. The operational question is: what prevailing role should this gateway play in my checkout? The answer determines the tool.

What they really cost: scenario over one operating month
Here is a transparent calculation based on a realistic B2B scenario. The assumptions are declared, so you can adapt the calculation to your case.
Scenario assumptions
Monthly revenue: €50,000. Split: 80% on Stripe (€40,000), 20% on PayPal (€10,000). Stripe card mix: 60% EU cards, 40% non-EU cards. Number of transactions: 60 on Stripe, 30 on PayPal. Share of Stripe volume in a currency other than EUR: 15%.
| Calculation item | Base | Rate | Cost |
|---|---|---|---|
| Stripe EU card volume (60% of €40,000) | €24,000 | 1.5% + €0.25 × 36 transactions | €360 + €9 = €369 |
| Stripe non-EU card volume (40% of €40,000) | €16,000 | 2.5% + €0.25 × 24 transactions | €400 + €6 = €406 |
| Stripe currency conversion (15% of €40,000) | €6,000 | 1.0% | €60 |
| PayPal volume (20% of €50,000) | €10,000 | 3.49% + €0.49 × 30 transactions | €349 + €14.70 = €363.70 |
| PayPal international fee (assumption 20%) | €2,000 | average additional fee | ~€40 |
| Total monthly fees | €50,000 | — | ~€1,239 |
How to read the result:
On €50,000 in monthly revenue, Stripe handles €40,000 at a total cost of €835 (€369 + €406 + €60). PayPal handles €10,000 at a total cost of ~€404 (€363.70 + €40).
The average cost on Stripe is approximately 2.09%, while on PayPal it is approximately 4.04%. The difference is mainly due to the card mix (Stripe has lower fees on EU and non-EU cards) and PayPal’s higher fixed component.
A possible configuration is to keep Stripe as the primary infrastructure and use PayPal for customers who prefer it, accepting a higher average cost on that volume share in exchange for broader payment method coverage.
A gateway cost without a calculation is data you cannot adapt to your case. With the declared assumptions, you can substitute your volumes, your card mix, and your number of transactions to obtain your real cost. This is the true value of the calculation: not the final number, but the structure you can reuse.
The 5 most costly mistakes when choosing a gateway
These mistakes are not necessarily disastrous individually. They become relevant when they repeat for months and block business growth.
A widely used gateway is not automatically suitable for your business model, your volume, or your customer type. A B2B SaaS and a small merchant have different needs.
Percentage fees vary by card, country, and account type. Currency conversion adds a further cost. Always compare the total cost on a typical transaction.
Disputes and chargebacks are part of international commerce. A gateway with a structured dispute process reduces resolution times and the risk of losses.
A frozen account blocks cash flow. Keeping a second active gateway reduces operational risk and allows redirecting payments if necessary.
The gateway choice depends on the company’s legal form and tax residence country. Opening before defining the structure can create compliance issues.
A gateway without a monthly fee is not automatically convenient. The real cost hides in transaction fees, currency conversion, dispute fees, and payout costs to foreign accounts. Always compare the total cost on a realistic volume, not just the “free” label.
When volumes grow, changing gateway requires re-engineering the checkout, migrating data, and updating accounting reconciliation. It is better to define the role of each gateway before volume makes the system difficult to modify.
The SmartStackHubPro roadmap for choosing a gateway
A practical sequence to build the payment architecture without trying to optimize everything in a single day.
Do you sell subscriptions, one-off products, or services? The model determines the features you need (recurring billing, simple checkout, split payments).
Card, PayPal, bank transfer, local wallets. Your B2B customers’ habits determine which methods you must cover.
Calculate the total cost on a realistic volume, including base fee, currency conversion, and payout. Compare the two gateways on your specific case.
If the model is SaaS or marketplace with custom checkout, Stripe tends to be the primary candidate. If the model is simple and activatable without development, PayPal.
If your customers use different methods or if hold risk is relevant for your sector, consider adding the second gateway to broaden coverage.
Check fees, disputes, chargebacks, and payout times. An efficient payment architecture is also a verifiable architecture.
If you cannot describe in a few sentences which gateway you use, why you use it, and how you reconcile flows, the payment architecture probably needs to be simplified.

Frequently asked questions about Stripe and PayPal for B2B e-commerce
The answers summarize the article’s framework. Provider conditions may change.
Is Stripe suitable for B2B e-commerce?
Yes. Stripe is designed for custom technical integrations, recurring billing, API-based payments, and multi-currency management. It is particularly suited for B2B platforms, SaaS, marketplaces, and companies with recurring revenue that require control over the payment flow.
Is PayPal suitable for B2B e-commerce?
Yes, especially for companies that want to activate payments quickly without technical development and for end customers who recognize the PayPal brand as a trust guarantee. PayPal also offers APIs and advanced merchant tools, but its prevailing role alongside Stripe tends to be that of an additional payment method.
Which gateway has lower fees?
It depends on the transaction type, the card used, and the jurisdiction. Stripe tends to have lower fees on international cards than PayPal. For domestic EU payments, the differences narrow. Always verify the conditions published on the official websites.
Can I use Stripe and PayPal together?
Yes. A possible configuration is to use Stripe as the primary infrastructure for cards, subscriptions, and custom checkout, and PayPal as an additional payment method for customers who prefer it. It adds a second integration and a second accounting reconciliation, but it broadens payment method coverage.
Which of the two handles disputes better?
Both offer dispute management tools with documentary evidence collection. PayPal has a consolidated buyer/seller protection policy and a structured resolution process. Stripe offers a dispute system managed through a dashboard with evidence upload and defined timelines.
Does Stripe require development skills?
To fully leverage the API and advanced features, yes. Stripe can be integrated via plugins on platforms like Shopify, WooCommerce, and Magento, but advanced customization requires technical skills. PayPal offers simpler integrations even without development, while also providing APIs for those who want to integrate it programmatically.
Can PayPal block or freeze a business account?
PayPal applies compliance checks that can lead to temporary limitations or fund holds in cases of suspicious activity, abnormal volumes, or documentary verifications. The phenomenon is documented and should be considered in operational planning. For this reason, a possible configuration is to keep a second active gateway.
Which of the two supports more currencies?
Stripe supports over 135 currencies and operates in approximately 45 countries. PayPal supports approximately 25 currencies and operates in over 200 markets. Stripe’s currency count is higher, but the number of markets reachable with PayPal is greater.
Stripe or PayPal for a B2B SaaS?
For a B2B SaaS with recurring revenue, automatic billing, and multiple plans, Stripe Billing tends to fill the role of primary infrastructure. PayPal can be added as an additional payment method to broaden coverage, but it does not replace Stripe’s native subscription management.
Which should I choose if I operate mainly in Italy?
If you operate in Italy with domestic customers and SMEs, both work. Stripe tends to be preferred for structured e-commerce integrations; PayPal for quick checkouts and customers who recognize the brand. The choice depends on volume, margin, and the team’s technical inclination.
Stripe or PayPal? It depends on the prevailing role they need to play in the checkout.
After comparing fees, countries, currencies, disputes, and features, the answer is not “one is better”. The correct question is: which of the two solves the problem you have right now?
If you have a B2B SaaS with recurring revenue, a marketplace, or an e-commerce with custom checkout, Stripe tends to occupy the role of primary infrastructure. It offers APIs, automatic billing, subscription management, fraud tools, and lower fees on international cards. It is designed to manage the payment flow programmatically.
If you need to activate payments quickly without technical development, or if your end customers prefer paying with PayPal for brand trust, PayPal tends to occupy the role of additional payment method. The checkout is ready, integration is simple, the brand is recognized. But control over the payment flow is lower than with an infrastructure like Stripe.
The operational truth is that a possible configuration is to use Stripe as the primary infrastructure and PayPal as an additional payment method. It is not a compromise: it is a broadening of payment method coverage, with a higher average cost on that volume share.
Before opening an account, therefore, do not ask yourself “which is best”. Ask yourself: what prevailing role should this gateway play in my payment architecture? The answer determines the choice.
