How the Leading Online Payment Gateways Compare in Practice
The table highlights the headline differences, but payment processing for ecommerce costs should be modelled using your real order data. A provider with a lower domestic card rate can become more expensive after commercial cards, international payments, currency conversion, disputes, subscription tools, and platform fees are included.
The mini reviews below explain why each provider ranks where it does, which merchants it is most likely to suit, and the trade-offs to check before migrating checkout or stored customer payment details.
1) Stripe: Best Overall Ecommerce Payment Gateway
Best for: Ecommerce businesses that want broad platform compatibility, flexible checkout options, strong APIs, and a clear route from a simple hosted checkout to a more advanced payment stack.
Why it ranks first: Stripe offers the strongest overall balance for the broadest range of online sellers. It supports hosted and embedded checkout, more than 100 payment methods, 135+ currencies, marketplace payments, subscriptions, fraud controls, and extensive ecommerce integrations. It is easier to start with than the enterprise platforms but has more room to scale than most small-business processors.
Standard UK pricing starts at 1.5% + 20p for standard UK cards. However, premium UK cards, EEA cards, international cards, currency conversion, disputes, Billing, Tax, and some other products have separate or higher charges. The effective rate therefore depends heavily on the store's payment mix.
- Pros: Excellent integrations and documentation; flexible checkout; built-in fraud protection; strong support for subscriptions, marketplaces, and international expansion.
- Cons: Cross-border and add-on costs can accumulate; high-volume merchants may negotiate better economics elsewhere; fund reviews or reserves can affect cash flow.
Choose Stripe if: You want one ecommerce payment processing gateway that works with mainstream ecommerce platforms today and can support custom development later.
Avoid Stripe if: You need a traditional dedicated merchant account relationship, unusually complex high-volume pricing, or an industry Stripe does not support.
2) Shopify Payments: Best for Shopify Stores
Best for: Shopify merchants who want native checkout, payouts, dispute management, and reporting without paying Shopify's additional fee for using a third-party payment provider on eligible transactions.
Why it ranks second: Shopify Payments is the logical default for most eligible Shopify stores. Setup is handled inside Shopify, Shop Pay can reduce checkout friction, and online payment processing and reporting sits beside orders and inventory. Card rates vary by Shopify plan, while using another processor can add Shopify's own third-party transaction fee on top of the provider's processing charge.
- Pros: Fast native setup; unified administration; Shop Pay; no separate payment-gateway subscription; avoids Shopify's extra third-party provider fee where applicable.
- Cons: Shopify-only; less payment-stack independence; eligibility restrictions apply; moving platform also means changing the native payment setup.
Choose Shopify Payments if: Your store already runs on Shopify and you do not have a specialist processing requirement that justifies the added cost and complexity of another gateway.
Avoid it if: You need a gateway that can move with you to WooCommerce, Magento, a headless stack, or a custom platform.
3) PayPal: Best Secondary Option for Buyer Familiarity
Best for: Stores that want a recognisable wallet and an additional checkout choice alongside their main card processor.
Why it ranks third: PayPal's main advantage is not that it is universally cheaper or technically stronger than Stripe. Its advantage is customer familiarity and the ability to let shoppers pay through an existing PayPal account. That can make it valuable as a secondary method, particularly for first-time buyers or audiences that actively prefer PayPal.
PayPal now offers wallet, card, pay later, payment-link, and enterprise payment options. Its UK fee schedule varies by product and payment type, so merchants should calculate wallet, card, international, fixed, dispute, and currency conversion charges rather than relying on one headline rate.
- Pros: Strong consumer recognition; broad ecommerce integrations; quick standard setup; useful as a second checkout method.
- Cons: Complex fee schedule; currency conversion can be expensive; account limitations and reserves can affect access to funds; disputes may require careful evidence handling.
Choose PayPal if: Customer payment preference matters and you want to offer PayPal beside your primary card checkout.
Avoid relying on it alone if: You want the simplest fee forecasting, lower-cost multi-currency settlement, or maximum control over the checkout experience.
4) Square: Best for Small Omnichannel Retailers
Best for: Small shops, pop-ups, hospitality businesses, and service providers that want online and in-person payments in one straightforward system.
Why it ranks fourth: Square is one of the best payment processor for ecommerce as it combines ecommerce checkout, payment links, invoices, point-of-sale software, card readers, inventory, and reporting. That makes it more practical than a developer-led gateway for merchants whose customers buy both online and face to face.
Square currently charges 1.4% + 25p for UK cards processed through Square Online, Online Checkout, or its ecommerce API, and 2.5% + 25p for non-UK cards. The basic payment account has no monthly fee, although paid online-store plans, hardware, instant transfers, and other products cost extra.
- Pros: Simple setup; strong POS tools; transparent UK online pricing; unified online and physical-store reporting.
- Cons: Less suitable for complex global payment orchestration; fewer advanced developer controls than Stripe; non-UK card costs are higher.
Choose Square if: Your business needs a practical online-plus-POS system more than a deeply custom payment infrastructure.
Avoid it if: You operate a complex marketplace, need extensive local acquiring, or have a large engineering team optimising authorisation performance.
5) Mollie: Best for UK and European Payment Methods
Best for: UK merchants selling into Europe who need cards plus regional payment methods such as iDEAL, Bancontact, SEPA, Klarna, and Bacs.
Why it ranks fifth: Mollie combines relatively simple onboarding with clearly published per-method pricing and strong European coverage. Its UK domestic consumer Visa and Mastercard rate starts at 1.2% + 20p, which is competitive, while plugins cover major ecommerce platforms.
The headline domestic rate does not apply to every card. UK commercial and European cards, international cards, American Express, PayPal, Klarna, and other payment methods have their own rates. Stores should model their actual card and country mix before deciding that Mollie is the lowest-cost option.
- Pros: Transparent payment-method pricing; strong European coverage; competitive domestic consumer-card rate; useful ecommerce integrations.
- Cons: Commercial and cross-border card rates can be much higher; smaller ecosystem than Stripe; not the strongest option for complex global enterprises.
Choose Mollie if: Europe is a meaningful sales market and local payment methods matter to conversion.
Avoid it if: Most transactions are international cards outside Europe or you need enterprise payment orchestration across many acquiring regions.
6) Airwallex: Best for Cross-Border and Multi-Currency Ecommerce
Best for: Ecommerce businesses that collect, hold, convert, and settle money across several countries and currencies.
Why it ranks sixth: Airwallex combines online payments with multi-currency business accounts, foreign exchange, transfers, payment links, plugins, APIs, and like-for-like settlement in more than 20 currencies. It supports cards and more than 160 local payment methods, making it particularly relevant to cross-border operators.
UK Visa and Mastercard transactions start at 1.3% + 20p, EEA cards at 2.4% + 20p, and international cards at 3.15% + 20p. The Explore plan is £19 per month, but the fee is waived when the business deposits at least £10,000 during the month or holds a minimum £10,000 balance at the end of the subscription period. Payment processing and other transaction charges still apply.
- Pros: Strong multi-currency toolkit; competitive UK card pricing; many local methods; useful for global collections, settlement, FX, and payouts.
- Cons: Monthly fee may apply; the broader finance platform adds complexity; less compelling for a small domestic-only store.
Choose Airwallex if: International collections, currency balances, FX, and cross-border settlement are central to the business.
Avoid it if: You only sell domestically and want the simplest possible gateway with no balance or monthly-plan considerations.
7) Adyen: Best for Enterprise Omnichannel Commerce
Best for: Large retailers and global brands that want online, mobile, and in-store payments on one acquiring and data platform.
Why it ranks seventh: Adyen is one of the strongest payment platforms in the list, but it ranks below the self-service providers because it is not intended for the typical small ecommerce store. Its value appears at scale: unified commerce, direct acquiring, local payment methods, detailed payment data, risk tools, and control over international payment performance.
Adyen charges a fixed processing fee plus a fee determined by the payment method. It publishes interchange++ structures for cards, has no setup or monthly fee, and applies a minimum invoice depending on the merchant's industry or business model. Exact economics should be obtained directly from Adyen.
- Pros: Enterprise-grade acquiring; unified online and in-person commerce; international reach; sophisticated risk and payment-performance tools.
- Cons: Sales-led onboarding; minimum invoice; significant implementation and operational requirements; excessive for most small stores.
Choose Adyen if: Payment acceptance is a strategic function managed across countries, channels, and large transaction volumes.
Avoid it if: You need a quick plug-in setup for a new or relatively simple ecommerce store.
8) Checkout.com: Best for High-Growth Payment Optimisation
Best for: High-growth ecommerce, marketplaces, fintech businesses, and international merchants with teams actively managing authorisation, fraud, and payment data.
Why it ranks eighth: Checkout.com offers a unified payments API, processing in more than 150 currencies, domestic coverage in 45+ countries, fraud tools, and granular transaction data. It is a credible alternative when a growing business needs more tailored payment performance and account support than a standard self-service gateway provides.
Pricing is tailored to the merchant and can use flat-rate or interchange++ structures. Checkout.com states that it has no setup or account-maintenance fees, but it does not publish a universal self-service transaction rate. A sales conversation and full proposal are required.
- Pros: Strong international coverage; unified API; detailed analytics; fraud tools; dedicated account and integration support.
- Cons: No public headline rate; sales-led onboarding; generally needs developer and payment-operations resources; not aimed at small beginners.
Choose Checkout.com if: Payment approval rates, data, routing, and international growth justify a tailored enterprise relationship.
Avoid it if: You want immediate self-service signup and a simple published rate.
9) WooPayments: Best Native Option for WooCommerce
Best for: WooCommerce store owners who want to manage payments, payouts, disputes, and transaction reporting from the WordPress dashboard.
Why it ranks ninth: WooPayments is not the most portable gateway, but its native WooCommerce administration makes it a practical alternative to installing and managing a separate payment provider plugin. UK card pricing starts at 1.5% + 25p, with no separate monthly payment-processing fee.
International cards add 2%, currency conversion adds another 2%, and disputes have a separate fee. VAT can also apply to WooPayments service fees unless the merchant supplies a valid VAT ID and the reverse-charge treatment applies. Merchants using subscriptions should also check whether an additional billing-engine fee applies to their setup.
- Pros: Native WooCommerce management; familiar WordPress workflow; cards and local methods; no separate monthly gateway fee; simpler reconciliation inside the store.
- Cons: WooCommerce-only; international and currency charges can stack; VAT and optional-product fees require attention; less portable than a direct Stripe account.
Choose WooPayments if: Operational simplicity inside WooCommerce matters more than gateway portability.
Avoid it if: You expect to change ecommerce platform, want direct control over a standalone gateway relationship, or sell heavily across currencies.
10) Worldpay: Best for Established UK Merchants
Best for: Established UK businesses that value a long-standing acquiring provider, ecommerce and in-person options, and the ability to discuss custom volume pricing.
Why it ranks tenth: Worldpay remains a relevant UK payment provider with online processing, payment links, virtual-terminal, point-of-sale, and global enterprise capabilities. It ranks below the more modern self-service gateways because contract and integration complexity can be higher.
Worldpay currently advertises pay-as-you-go ecommerce pricing from 1.3% + 20p for Visa and Mastercard consumer cards and 2.9% + 20p for commercial cards and American Express. Other charges may apply, quotes are subject to contract, and the online application terms mention a minimum 18-month contract. Higher-volume merchants can request custom pricing.
- Pros: Strong UK market presence; online and in-person products; virtual terminal and payment links; custom pricing for larger volumes.
- Cons: Contract commitment and extra charges need careful review; less transparent than a fully self-service provider; developer experience can be more cumbersome.
Choose Worldpay if: You prefer an established UK acquiring relationship and are willing to compare a full written quote and contract.
Avoid it if: You want the fastest self-service setup, the shortest commitment, or the cleanest developer experience.
How To Choose The Right Online Payment Gateway
Choosing an online payment gateway is about more than just transaction fees. The right option depends on your platform, customer locations, sales model, and future business plans.
Start With Your Ecommerce Platform
Your ecommerce platform narrows your choices immediately. If you run a Shopify store, Shopify Payments avoids the platform's third-party surcharge.
WooCommerce works well with Stripe, PayPal, Mollie, and many others. Magento and custom-built stores often use Stripe, Adyen, or Checkout.com.
Always check for native integration support before comparing fees.
Match The Gateway To Your Sales Geography
An ecommerce payment gateway suited for domestic sales may not perform well for international transactions. If you sell across Europe, consider Mollie, Adyen, or Stripe for local payment method support.
For businesses selling in both the UK and the United States, Stripe and PayPal are practical starting points because both have broad platform support. Airwallex can be attractive where multi-currency collection and settlement are more important, while Adyen and Checkout.com become relevant at enterprise scale.
Compare Flat-Rate Vs Interchange-Plus Pricing
Flat-rate pricing (e.g. 1.5% + 20p) is predictable and simple. Interchange-plus pricing passes through the actual card network cost plus a markup.
Flat-rate pricing often suits merchants that value simplicity. At higher volumes, a tailored or interchange++ proposal may reduce costs, but the result depends on card mix, transaction values, regions, and the provider's markup.
Adyen publishes a processing-fee-plus-payment-method structure and supports interchange++ card pricing. Checkout.com offers tailored flat-rate or interchange++ pricing, while Worldpay can provide custom transaction rates for larger volumes.
Check Supported Payment Methods
Beyond Visa and Mastercard, consider if your customers use Apple Pay, Google Pay, Klarna, iDEAL, SEPA, or PayPal. Local payment methods can boost conversion in specific markets.
Stripe, Mollie, Airwallex, and Adyen provide particularly broad payment-method coverage. Square is easier for straightforward UK retail but is less extensive for complex international payment localisation.
Review Fraud Tools And Chargeback Handling
Fraud detection quality varies between gateways. Stripe Radar, Adyen RevenueProtect, and Checkout.com use machine learning to flag suspicious transactions.
Dispute rules, evidence requirements, and seller-protection eligibility vary by provider and transaction. This matters in dispute-heavy categories, so check how fraud tools and chargebacks are handled and whether additional fees apply.
Assess Integration Effort And Developer Dependence
Some gateways, like Shopify Payments and Square, require minimal technical work. Others, such as Adyen and Checkout.com, need developer resources for integration and maintenance.
If you lack a development team, choose a gateway with strong pre-built plugins for your platform.
Consider Payout Timing And Cash Flow
Payout schedules differ by gateway, country, payment method, account history, and risk profile. Standard payouts may take several business days, while faster or instant payout options can have separate fees.
Some providers make funds visible in an account balance before bank settlement is complete. New accounts, unusual transaction patterns, disputes, reserves, or compliance reviews can also delay access to funds.
For cash-flow-sensitive businesses, verify payout timing before choosing.
Factor In Lock-In And Migration Difficulty
Switching online payment gateways can be complex, especially when a store has saved payment tokens or active subscriptions. Ask whether tokens can be exported or migrated, how subscriptions would transfer, and whether customers would need to enter their payment details again.
Shopify Payments and WooPayments increase dependence on their respective ecommerce platforms. Worldpay and other contracted providers may include minimum terms or early termination costs, so read the written agreement carefully.
Always assess the cost and complexity of switching before signing up.
Pricing And Fee Traps To Watch
Online payment gateway costs often go beyond the headline transaction rate. The real cost can include several layers that are easy to miss at sign-up.
Transaction Fees And Cross-Border Mark-ups
Most ecommerce payment gateways charge a percentage plus a fixed fee per transaction. For UK domestic cards, Stripe charges 1.5% + 20p.
Stripe currently charges 3.15% + 20p for international cards, while EEA cards, premium UK cards, and currency conversion have different rates. Other gateways apply their own cross-border or international pricing.
If many of your sales are international, these differences can impact margins.
Monthly Fees And Gateway Charges
Stripe, PayPal's standard acceptance options, Square's basic payment account, and Mollie's online payment service do not require a standard monthly processing fee. Shopify Payments and WooPayments are tied to their respective ecommerce platforms, so the wider platform costs still matter.
Airwallex Explore costs £19 per month unless its deposit or balance threshold is met. Adyen applies a minimum invoice depending on the business model, while Worldpay pricing and other charges depend on the selected contract. Always request the complete written fee schedule.
Consider these fees, especially at lower volumes where monthly charges increase your effective per-transaction cost.
Refund Costs And Chargeback Fees
Some payment providers retain all or part of the original processing fee when a merchant issues a refund. Check the current refund policy because the cost can become material in categories with frequent returns.
Dispute and chargeback fees vary by provider, and high dispute rates can trigger account reviews, reserves, restrictions, or termination. Compare the fee, evidence process, and treatment of successfully defended disputes.
Currency Conversion And Settlement Costs
Accepting payments in currencies other than GBP and settling in GBP triggers a conversion fee. Stripe charges 2% for currency conversion.
PayPal and other providers use transaction-specific currency conversion rates or mark-ups. Compare the complete conversion and settlement cost rather than assuming that the processor with the lowest domestic card rate will also be cheapest internationally.
Platform Transaction Fees On Top Of Gateway Fees
Some ecommerce platforms add their own transaction fee. Shopify can charge up to 2% per transaction when a third-party payment provider is used, with the exact rate depending on the Shopify plan.
BigCommerce does not charge additional transaction fees. WooCommerce does not charge platform transaction fees, as it is self-hosted.
Always calculate the combined platform and gateway cost.
Add-Ons For Billing, Tax, Fraud, And POS
Features that seem included may be paid add-ons. Stripe Tax is billed per transaction.
Advanced fraud, payment optimisation, subscription billing, tax tools, instant payouts, POS hardware, disputes, and currency conversion may be priced separately. Check which tools are included in the quoted processing rate and which create another percentage or fixed charge.
Confirm whether recurring billing, tax automation, or in-person payments are included or require upgrades.
Final Verdict: Best Ecommerce Payment Gateway
There is no single online payment gateway that fits every ecommerce business. The best choice depends on your platform, customer geography, transaction volume, and technical needs.
Best For Shopify Stores
Shopify Payments is the best default online payment gateway for most eligible Shopify sellers. It avoids Shopify's additional third-party payment-provider fee and keeps checkout, orders, payouts, and disputes in the same administration area.
A third-party provider may still be justified when Shopify Payments does not support the business, a required local payment method is missing, or negotiated enterprise economics outweigh Shopify's additional fee.
Best For Buyer Trust At Checkout
PayPal remains one of the most recognisable payment options for consumers. Offering it as a secondary method can reduce checkout friction for first-time buyers and customers who prefer paying through an existing PayPal account.
Best For Omnichannel Retail
Square is the strongest option for small businesses selling both online and in person. Its unified dashboard, POS tools, transparent online pricing, and basic account with no monthly processing fee suit retailers, hospitality businesses, and market traders.
Best For European Merchants
Mollie is a strong option for businesses focused on Europe. It supports iDEAL, Bancontact, SEPA, Klarna, and other local payment methods with straightforward onboarding.
Best For Cross-Border Ecommerce
Airwallex is the strongest specialist choice for businesses that need payment acceptance, multi-currency accounts, like-for-like settlement, foreign exchange, and international transfers in one platform. Domestic-only sellers should weigh those benefits against its possible monthly fee and additional complexity.
Best Native Option For WooCommerce
WooPayments is the easiest native option for merchants that want to manage payments from the WooCommerce dashboard. Direct Stripe or Mollie integrations may be preferable when portability, European methods, or a separate gateway relationship matters more.
Best For Enterprise And Global Scale
Adyen and Checkout.com are top options for high-volume, global businesses. Both offer local acquiring, advanced fraud tools, and custom pricing.
Adyen suits businesses seeking unified commerce across online, mobile, and in-store. Checkout.com is ideal for teams needing granular payment routing and performance data.
Best Overall For Flexibility
Stripe is the top recommendation for most ecommerce businesses. It offers transparent pricing, wide platform compatibility, strong developer tools, and built-in fraud detection.
It works with WooCommerce, Shopify, Magento, BigCommerce, and custom builds.
Frequently Asked Questions
These are common questions from ecommerce merchants comparing online payment gateways.
What is the best payment gateway for ecommerce?
Stripe offers the best overall balance for most ecommerce businesses because it combines broad platform support, flexible checkout, fraud tools, subscriptions, international payments, and a strong developer ecosystem.
Shopify Payments is the better default for eligible Shopify stores, while Square is easier for small omnichannel retailers.
What should you compare when choosing a gateway for international customers?
Compare cross-border card rates, currency conversion, settlement currencies, local payment methods, local acquiring, refunds, disputes, payout timing, and any monthly or platform charges.
Use your actual card and country mix because the lowest domestic headline rate may not produce the lowest total cost.
Which online payment gateways suit businesses selling in the UK and the USA?
Stripe and PayPal both support UK and US ecommerce and integrate with many store platforms. Airwallex is worth comparing for multi-currency collections and settlement.
Larger businesses should also obtain proposals from Adyen and Checkout.com because enterprise pricing and local acquiring can change the result.
How do Stripe and Shopify Payments compare?
Shopify Payments is native to Shopify and avoids Shopify's additional third-party payment-provider fee on eligible transactions. Stripe is a standalone platform with broader ecommerce-platform support and more direct API control.
Shopify merchants should usually begin with Shopify Payments unless a specialist requirement justifies another gateway and the extra Shopify fee.
What security and fraud features should an online payment gateway provide?
Look for PCI DSS compliance, tokenisation, 3D Secure support, configurable fraud rules, risk scoring, dispute-management tools, access controls, and clear security documentation.
Merchants still remain responsible for configuring their store, staff access, plugins, and checkout implementation securely.
How does a payment gateway differ from a payment processor?
An online payment gateway securely captures and transmits payment information, while a processor communicates with card networks and banks to authorise and settle the transaction.
Providers such as Stripe and Adyen combine gateway, processing, and acquiring functions. An all-in-one provider is usually easier for a smaller store, while larger businesses may separate parts of the payment stack.
Should an ecommerce store offer PayPal as well as card payments?
PayPal can be valuable as a secondary method because some customers prefer using an existing PayPal account. It does not need to be the primary card processor.
Compare its transaction, dispute, and currency-conversion costs, then measure whether offering PayPal improves completed checkouts for your actual audience.
What is replacing PayPal?
PayPal remains a major player, but many users and businesses are shifting toward alternatives such as Stripe, Wise, Square, Venmo, Zelle, Apple Pay, Google Pay, and Revolut.
Rather than one company replacing PayPal, the market is fragmenting as newer platforms offer lower fees, faster transfers, better international payments, or integrated business tools.
