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

vs

PayPal and Mollie are two of the most widely used online payment providers available to UK businesses in 2026. PayPal suits businesses that want instant brand recognition and a fast setup, particularly those selling to consumers who already hold a PayPal account. Mollie is a better fit for e-commerce merchants who want clean API access, transparent pay-as-you-go pricing, and a wider range of European payment methods without a monthly contract tying them in.

PayPal vs Mollie: Fee Comparison

What is PayPal?

PayPal is a US-founded payments company established in 1998 and now one of the most recognised payment brands in the world. In the UK, it processes payments for millions of businesses ranging from sole traders on eBay to large retail brands. Its core product for merchants is PayPal Checkout, which lets shoppers pay using their PayPal balance, linked bank account, or any major debit or credit card. The standard transaction fee for UK Checkout payments is 1.99% with no monthly fee, though cross-border transactions attract additional fees that can reach 4.4% plus a fixed fee.

Beyond online payments, PayPal owns Zettle, a point-of-sale product that includes card readers starting at around £29 for the first device. This makes PayPal one of the few providers in this comparison that covers both online and in-person selling. Account holds and fund freezes are a genuine and widely reported risk with PayPal, particularly for newer merchants or those in higher-risk categories.

What is Mollie?

Mollie is a Dutch payment service provider founded in 2004 and headquartered in Amsterdam. It has grown rapidly across Europe and now serves over 250,000 businesses. UK merchants can sign up online without a monthly fee and start accepting payments the same day in most cases. Its headline rate for UK Visa and Mastercard transactions is 1.8% plus €0.25 per successful payment, which is competitive for lower-volume businesses but becomes less so at higher volumes compared with interchange-plus pricing from providers like Stripe or Adyen.

Mollie's strongest differentiator is its payment method coverage. It supports over 25 methods including PayPal, Apple Pay, Google Pay, Klarna, iDEAL, Bancontact, SEPA Direct Debit, Przelewy24, and Belfius, all managed through a single dashboard. That makes it particularly attractive for UK merchants expanding into Continental European markets. Mollie has no card machine or in-person hardware product, so it is an online-only solution.

PayPal vs Mollie: Features Compared

Payment Methods

PayPal Checkout accepts PayPal wallet payments, Pay Later (Buy Now Pay Later), Venmo in the US, and major debit and credit cards including Visa, Mastercard, and American Express. In the UK context, the primary draw is the PayPal wallet itself: roughly 44 million UK consumers hold a PayPal account, and enabling the button can lift conversion for merchants whose customers prefer not to type card details. Mollie covers all of that and adds iDEAL for Dutch buyers, Bancontact for Belgian shoppers, Klarna instalment payments, SEPA Direct Debit for subscription billing, and Przelewy24 for Polish customers. If your business sells across Europe, Mollie's method coverage is substantially broader.

Hardware and In-Person Terminals

PayPal offers in-person payments through Zettle, which it acquired in 2018. The Zettle Reader 2 costs around £29 plus VAT for new merchants and accepts chip and PIN, contactless, and digital wallet payments. It connects via Bluetooth to iOS and Android devices and settles funds next business day. Mollie has no equivalent hardware product. If your business needs face-to-face card acceptance alongside an online checkout, PayPal is the only realistic choice between these two.

Integrations

Both providers integrate with the major e-commerce platforms. PayPal connects natively with Shopify, WooCommerce, Magento, BigCommerce, and Wix, among others. Mollie offers official plugins for WooCommerce, Shopify, Magento 2, PrestaShop, OpenCart, and Craft Commerce. Mollie's REST API is widely regarded by developers as clean and well-documented, which matters for businesses building custom checkout flows. PayPal's API is functional but older in places, and some developers report more complexity when handling edge cases such as refunds and disputes programmatically.

International Support

PayPal operates in over 200 countries and supports 25 currencies, making it a strong option for businesses selling globally outside Europe. Cross-border fees are, however, a real cost: international transactions attract a fee of up to 4.4% plus a fixed currency-specific amount. Mollie focuses primarily on Europe and supports 25+ European payment methods with competitive European card rates. For businesses selling heavily into Continental Europe, Mollie's localised payment method support gives it a genuine advantage. For markets outside Europe, PayPal's global reach is wider.

Fraud and Risk Tools

PayPal includes its own fraud screening on every transaction and offers Seller Protection on eligible payments, which can cover merchants against unauthorised transaction chargebacks and item-not-received claims. The catch is that PayPal also uses aggressive risk algorithms that can result in account holds or fund reserves with little warning. Mollie supports 3D Secure authentication on card payments and integrates with Mollie's own fraud screening. It does not have a seller protection programme equivalent to PayPal's, but it has a significantly better reputation among UK merchants for account stability.

Customer Support

PayPal offers phone, live chat, and email support, but wait times and resolution quality draw consistent criticism in UK merchant forums and on Trustpilot. Its automated systems can lock accounts without clear explanation, leaving merchants unable to access funds for days or weeks. Mollie provides email and chat support and has built a reputation for more consistent and helpful responses, particularly for technical integration queries. Neither provider offers a dedicated account manager at standard pricing levels.

Pros and Cons

PayPal Pros and Cons

Pros

• Recognised by roughly 44 million UK consumers, which can improve checkout conversion
• Covers both online and in-person payments through Zettle hardware
• No monthly fee or long-term contract on the standard plan
• Seller Protection programme covers eligible transactions against certain chargeback types
• Available in over 200 countries, useful for merchants with a global customer base

Cons

• Account holds and fund freezes are a well-documented problem, particularly for newer or higher-volume accounts
• Cross-border transaction fees can reach 4.4% plus a fixed fee, significantly higher than domestic rates
• Funds settle to a PayPal balance first; moving money to your bank account takes one to three business days or costs 1.5% for instant transfer
• Customer support quality is rated poorly by a significant proportion of UK merchants

Mollie Pros and Cons

Pros

• Supports over 25 payment methods including Klarna, iDEAL, Bancontact, and SEPA Direct Debit through a single integration
• No monthly fee and no minimum volume requirement
• Clean, well-documented REST API that developers consistently rate highly
• Next business day bank settlement in most cases without an additional charge
• More consistent account stability and customer support reputation than PayPal among UK merchants

Cons

• No card machine or in-person hardware product, so unsuitable for face-to-face selling
• The fixed per-transaction fee of €0.25 makes costs relatively high at low average order values
• Less recognisable as a brand to UK consumers compared with PayPal, so no direct conversion uplift from the payment button itself
• No seller protection programme equivalent to PayPal's

Which is Better For...?

Small Retail Businesses With Physical and Online Sales

PayPal is the stronger choice here. The Zettle Reader 2 gives you an affordable card machine for in-store sales, and the online Checkout button covers your website. Running both through one provider keeps your reporting in one place. Mollie simply does not offer a hardware option, so a physical retailer would need a second provider for face-to-face transactions.

Online-Only E-commerce Selling Across Europe

Mollie is the better fit for most European e-commerce operations. Its support for iDEAL, Bancontact, Klarna, Przelewy24, and SEPA Direct Debit means you can localise your checkout for Dutch, Belgian, Polish, and German customers without additional integrations. A UK merchant processing €50,000 a month across Europe will find Mollie's single-integration approach significantly less complex than bolting multiple methods onto a PayPal setup.

Subscription and Recurring Billing Businesses

Mollie has the edge for subscription businesses. Its SEPA Direct Debit support, combined with its subscriptions API, allows automated recurring charges across European bank accounts. PayPal does support recurring billing through its Billing Agreements product, but the implementation is more complex and the risk of account holds affecting live subscriptions is a genuine operational concern for businesses dependent on predictable billing cycles.

High-Volume Merchants

Neither PayPal nor Mollie is the optimal choice at very high volumes. At £500,000 or more per month, interchange-plus pricing from providers like Adyen, Stripe, or a traditional acquirer will almost certainly produce lower effective rates than the blended fees both of these providers charge. At that scale, it is worth using the Compare Card Fees comparison tool to benchmark quotes across a wider range of acquirers.

Our Verdict

The right choice between PayPal and Mollie depends almost entirely on what your business sells and where your customers are. For a UK merchant selling to British consumers through a simple online store, PayPal's brand recognition is a genuine conversion asset and the 1.99% flat rate is straightforward to budget around. Add in Zettle if you also sell face-to-face, and PayPal covers most bases for a small generalist business. The account hold risk is real, though, and worth weighing seriously if cash flow is tight.

Mollie wins clearly for e-commerce businesses targeting European markets. The breadth of local payment methods, the clean API, and the more reliable settlement process make it a more predictable operational choice. The absence of any in-person product is a firm limitation, and the fixed €0.25 per-transaction element means it suits merchants with average order values of at least £20 to keep the effective rate reasonable.
