Full Rankings

Stripe

4.6

4.6 / 5.0

Transaction fee: 2.9% + $0.30

Why it's good

Stripe is the best overall payment gateway for ecommerce. Its hosted Checkout page is optimized for conversion with smart payment method display, address autocomplete, and real-time card validation. Stripe supports 100+ payment methods and 135+ currencies. Stripe Radar provides ML-powered fraud detection included free with every account. Integrations with Shopify (via Stripe), WooCommerce, BigCommerce, and every major ecommerce platform are robust. For custom stores, Stripe Elements lets you build fully branded checkout experiences.

Why it might not be

Stripe's flat-rate pricing (2.9% + $0.30) can become expensive at high volumes compared to interchange-plus providers. Reaching a human for support can be slow on standard plans. Some non-technical merchants find Stripe's dashboard and configuration options overwhelming.

Adyen

4.5

4.5 / 5.0

Transaction fee: Interchange++ (€0.11 processing + scheme fee + interchange)

Why it's good

Adyen is the premier choice for high-volume ecommerce businesses. Its interchange-plus pricing saves money at scale, and its RevenueAccelerate engine maximizes authorization rates through intelligent routing and local acquiring in 30+ countries. Adyen supports 250+ payment methods — more than any other provider. Network tokenization and real-time account updater reduce involuntary churn from expired cards. Major ecommerce brands like eBay, ASOS, and Etsy rely on Adyen.

Why it might not be

Adyen is not accessible to small ecommerce stores — it requires minimum processing volumes and a sales-driven onboarding process. Its drop-in checkout components are capable but less customizable than Stripe Elements. Pricing complexity (interchange-plus with scheme fees) can be harder to predict.

Checkout.com

4.4

4.4 / 5.0

Transaction fee: Custom pricing (typically ~2.5% + $0.20 for mid-market)

Why it's good

Checkout.com offers aggressive interchange-plus pricing that appeals to growing ecommerce businesses processing significant volume. Its modern API and Flow payment orchestration tool make integration straightforward. Strong authorization rate optimization and local acquiring in key markets help maximize revenue. Checkout.com also has a good track record serving digital commerce companies in competitive verticals.

Why it might not be

Checkout.com is not self-serve — it requires a sales process and minimum volumes. Its ecosystem is narrower than Stripe's, with no built-in billing, marketplace, or extensive no-code tools. Fewer ecommerce platform plugins available out of the box compared to Stripe or Mollie.

PayPal

4.0

4.0 / 5.0

Transaction fee: 2.99% + $0.49

Why it's good

Adding PayPal as a checkout option can increase conversion by 28-44% thanks to its massive consumer trust and 400+ million active accounts. PayPal Checkout supports cards, PayPal balance, Venmo, and Pay Later options. For ecommerce stores, PayPal works best as a complementary payment method alongside a primary processor rather than the sole gateway.

Why it might not be

PayPal's fees are among the highest (2.99% + $0.49 for card processing, 3.49% + $0.49 for branded checkout). Using PayPal as your sole gateway means higher costs and less control over the checkout experience. PayPal's buyer protection policies can sometimes favor buyers unfairly in disputes, increasing merchant risk.

Mollie

4.2

4.2 / 5.0

Transaction fee: €0.25 + scheme rate (1.8% EU / 2.8% non-EU cards)

Why it's good

Mollie is an excellent ecommerce gateway for European online stores. Its plugins for WooCommerce, Magento, PrestaShop, and Shopify are well-maintained and easy to install. Native support for European payment methods (iDEAL, Bancontact, Klarna, SOFORT) at competitive prices helps European merchants optimize for their local market. The checkout experience is clean and conversion-optimized.

Why it might not be

Mollie only serves European merchants, limiting its usefulness for global ecommerce. Its fraud prevention tools are basic compared to Stripe Radar or Adyen's risk engine. The product range is narrower — no built-in marketplace tools, limited subscription features, and fewer payment methods than Adyen or Stripe globally.

Your payment gateway directly impacts your ecommerce conversion rate — studies consistently show that a poor checkout experience causes 17-20% of shoppers to abandon their cart. The right payment gateway for an online store goes far beyond simply processing credit cards. It needs to support the payment methods your customers prefer, offer a seamless checkout experience that minimizes friction, protect against fraud without blocking legitimate orders, and integrate smoothly with your ecommerce platform. For ecommerce businesses, checkout conversion is everything. Even a 1% improvement in payment acceptance rates can translate to significant revenue gains. That means your gateway needs smart retry logic, network tokenization, support for 3D Secure authentication, and the ability to route transactions optimally. Multi-currency support is critical if you sell internationally — customers are far more likely to complete a purchase when they see prices and pay in their local currency. Fraud protection matters too: ecommerce businesses face higher fraud rates than in-person retailers, and chargebacks are costly both in direct losses and processor penalties. The best payment gateways offer built-in machine learning fraud detection that adapts to your business patterns. We evaluated the leading payment processors on the criteria that matter most for ecommerce: checkout conversion optimization, payment method breadth, fraud prevention, ecommerce platform integrations, multi-currency support, and the ability to scale from hundreds to millions of transactions.
