Stripe vs Mollie UK 2026: Fees, Features & Which to Choose

vs

Stripe and Mollie are two of the most widely used online payment processors available to UK businesses in 2026. Both charge no monthly fee, operate on a pay-as-you-go basis, and support a broad range of payment methods. The key difference is focus: Stripe is built for developers and technical teams who want granular control over payments infrastructure, while Mollie targets small and medium-sized e-commerce businesses that want straightforward European payment coverage without writing much code. This page compares their fees, features, and weaknesses so you can decide which one fits your business.

Stripe vs Mollie: Fee Comparison

What is Stripe?

Stripe is a US-founded payment technology company, launched in 2010, that processes card payments and other payment methods for businesses of all sizes. Its UK entity, Stripe Payments UK Ltd, is authorised by the Financial Conduct Authority. In the UK, Stripe's standard rate for domestic Visa and Mastercard transactions is 1.5% + 25p. American Express transactions cost 2.5% + 25p. The platform is best known for its developer-first design: its API documentation is widely regarded as the most detailed in the industry, and most integrations require a developer to configure them properly.

Stripe also offers hardware terminals for in-person payments, a billing product for subscriptions, Stripe Connect for marketplaces, and a suite of financial tools including Stripe Issuing and Stripe Treasury. High-volume businesses can negotiate custom pricing through Stripe Plus or Stripe Enterprise. For a full breakdown of fees and features, see the Stripe UK review on Compare Card Fees.

What is Mollie?

Mollie is a Dutch payment service provider founded in 2004. It is regulated in the Netherlands by De Nederlandsche Bank and registered with the FCA in the UK as an e-money institution (reference 889196). Mollie positions itself as a simple, transparent payment processor for European e-commerce businesses. Its standard credit card transaction fee is 1.8% + 25p, with no monthly fee and no minimum volume requirement. The platform is particularly strong for merchants targeting mainland European customers, as it includes popular local payment methods such as iDEAL, Bancontact, and SOFORT as standard integrations.

Mollie's dashboard is clean and accessible to non-technical users. It integrates directly with WooCommerce, Shopify, Magento, and PrestaShop via official plugins, and requires minimal configuration to get started. Unlike Stripe, Mollie does not offer card terminal hardware, so it is suited exclusively to online payment collection.

Stripe vs Mollie: Features Compared

Payment Methods

Stripe supports Visa, Mastercard, American Express, Apple Pay, Google Pay, Link (Stripe's own accelerated checkout), SEPA Direct Debit, BACS Direct Debit, Klarna, Afterpay, iDEAL, and over 40 additional payment methods. Most require API configuration to activate. Mollie supports Visa, Mastercard, Apple Pay, Google Pay, iDEAL, Bancontact, SOFORT, SEPA Direct Debit, Klarna, and PayPal, among others. Mollie's key advantage is that European local payment methods are available out of the box without developer work. For UK-only businesses, the difference is minimal. For businesses selling to Dutch or Belgian customers, Mollie's native iDEAL and Bancontact support is a meaningful practical advantage.

Hardware and In-Person Payments

Stripe sells its own card terminal, the Stripe Reader S700, which costs £279 + VAT in the UK. It supports chip and PIN, contactless, and Apple Pay or Google Pay tap payments. In-person transaction fees sit at 1.7% + 5p for UK cards. Mollie has no card terminal product. If your business takes any face-to-face payments, Stripe is the only realistic choice between the two.

Integrations

Stripe integrates with over 500 platforms and tools, including Shopify, WooCommerce, Squarespace, Xero, QuickBooks, Salesforce, and Zapier. Many integrations are built and maintained by third parties. Mollie integrates natively with WooCommerce, Shopify, Magento 2, PrestaShop, OpenCart, and a smaller set of accounting tools. Mollie's plugin quality is generally consistent, but the breadth of available integrations is narrower than Stripe's. Businesses using more complex or bespoke tech stacks will find Stripe better supported.

International Support

Stripe processes payments in over 135 currencies and operates in 46 countries. Currency conversion carries an additional 2% fee on top of the standard transaction rate. Mollie operates across 30-plus European countries and supports around 35 currencies. For businesses selling predominantly within Europe, both providers cover the territory adequately. For businesses with significant trading volumes in North America, Asia, or Australia, Stripe's broader geographic reach is a practical advantage.

Fraud and Security Tools

Stripe Radar is the provider's machine-learning fraud detection tool. It is included at no extra cost on standard plans and blocks fraudulent transactions based on signals from Stripe's global network. Radar for Fraud Teams, which allows custom rules and review queues, costs an additional 2p per screened transaction. Both providers are PCI DSS compliant. Mollie includes basic fraud screening and SCA (Strong Customer Authentication) as standard, in line with FCA requirements. Stripe's Radar tooling is more sophisticated and more configurable than Mollie's fraud controls, which matters most to high-volume merchants with elevated fraud risk. For more on SCA requirements, see the guide to 3D Secure and Strong Customer Authentication.

Customer Support

Stripe offers 24/7 email and chat support, with phone support available on higher-tier plans. Its documentation is extensive and generally answers most technical questions without needing to contact support directly. Mollie provides email and phone support during business hours, plus a live chat function. Response times from Mollie are generally reported as good by smaller merchants. Neither provider offers a dedicated account manager to businesses on standard pay-as-you-go terms.

Which is Better For...?

Small Retail Businesses Taking In-Person Payments

Stripe is the clear choice here. Mollie has no card terminal product, so any business that needs to accept face-to-face card payments cannot use Mollie alone. Stripe's Reader S700 costs £279 + VAT and supports chip and PIN, contactless, and mobile wallets. In-person Stripe transactions cost 1.7% + 5p for UK cards, which is competitive for a pay-as-you-go terminal with no monthly rental fee.

Online-Only E-commerce Selling Across Europe

Mollie has a genuine edge for businesses selling to customers in the Netherlands, Belgium, and Germany. iDEAL accounts for the majority of online transactions in the Netherlands, and Mollie surfaces it natively without additional API work. Stripe supports iDEAL too, but its European card rate of 2.5% + 25p is higher than Mollie's 1.8% + 25p. For a business turning over £20,000 a month in European card sales, Mollie's lower rate saves around £140 a month compared to Stripe.

Developer-Led SaaS or Subscription Businesses

Stripe is significantly better suited to SaaS businesses, subscription platforms, and marketplaces. Stripe Billing handles complex subscription logic including trials, proration, usage-based pricing, and dunning management. Stripe Connect allows platforms to route payments to multiple connected accounts. Mollie offers basic subscription functionality, but it does not match Stripe's depth for businesses with complex recurring revenue models.

High-Volume Merchants Seeking Lower Rates

At high volumes, both providers offer the possibility of negotiated pricing. Stripe's Plus plan, starting at £149 per month, unlocks interchange-plus pricing and custom rates. Mollie offers volume discounts on request once you reach consistent monthly turnover, though the threshold is not publicly listed. For businesses processing over £100,000 per month in card payments, neither Stripe nor Mollie's standard rates are necessarily optimal. A dedicated merchant account through a provider such as Adyen or Worldpay may produce lower blended rates. Use the Compare Card Fees merchant services comparison tool to get tailored quotes.

Our Verdict

Stripe is the stronger all-round platform for businesses that have, or can access, developer resource. Its lower UK card rate of 1.5% + 25p, broader integration library, card terminal hardware, and more capable fraud tools make it genuinely versatile across online and in-person use cases. If your business sells primarily to UK customers, processes a mix of online and face-to-face payments, or needs custom checkout logic, Stripe is the better fit.

Mollie earns its place for online-only businesses targeting European customers, particularly those in the Netherlands, Belgium, and Germany. Its lower European card rate and out-of-the-box local payment method support remove friction from the checkout process for those audiences. It is also more accessible for small teams without a developer, thanks to clean plugins and a straightforward dashboard. The honest limitation is that Mollie's product breadth is narrower: no terminals, fewer integrations, and less configurable fraud controls.

Neither provider is the cheapest option for high-volume UK merchants. If you are processing more than £50,000 a month in card payments, a traditional merchant account with interchange-plus pricing may save you more than either pay-as-you-go model.
