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

vs

PayPal charges 2.9% plus a £0.30 fixed fee per transaction for UK Checkout payments, while Mollie charges 1.20% plus £0.20 per successful Visa or Mastercard transaction. For most UK businesses, PayPal is the simpler choice for mixed online and in-person selling, thanks to its Zettle card reader range and consumer brand recognition among roughly 44 million UK account holders. Mollie is the stronger pick for e-commerce merchants selling across Europe, offering over 25 payment methods, including iDEAL, Bancontact, Klarna, and SEPA Direct Debit, through a single integration and no monthly contract. Neither provider is ideal at very high volumes, where interchange-plus pricing from acquirers such as Adyen or Stripe typically produces lower effective rates.

Who Is This Page For?

This comparison is aimed at UK business owners deciding between PayPal and Mollie for online payment processing in 2026. It is most relevant if you run an e-commerce store, a subscription service, or a small retail business with both online and in-person sales. It is also useful if you currently use one provider and are considering switching to the other. If you process more than £500,000 a month, the Stripe vs Mollie comparison or a bespoke quote from an interchange-plus acquirer may be more relevant to your situation.

Key Facts: PayPal vs Mollie

PayPal vs Mollie: Full 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, a linked bank account, or any major debit or credit card. The standard transaction fee for UK Checkout payments is 2.9% plus a £0.30 fixed fee, with no monthly fee, though cross-border transactions attract additional fees that can reach 4.4% plus a fixed currency-specific amount.

Beyond online payments, PayPal owns Zettle, a point-of-sale product that includes card readers starting at around £29 plus VAT for new merchants. 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, particularly for newer merchants or those in higher-risk categories. You can read a full breakdown on the PayPal provider review page or compare its hardware range on the Zettle review page.

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 1.20% plus £0.20 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 payment provider.

PayPal vs Mollie: Features Compared

Payment Methods

PayPal Checkout accepts PayPal wallet payments, Pay Later (Buy Now Pay Later), and major debit and credit cards including Visa, Mastercard, and American Express. In the UK, the primary draw is the PayPal wallet itself. Roughly 44 million UK consumers hold a PayPal account, and enabling the checkout button can lift conversion for merchants whose customers prefer not to enter card details manually. 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. For businesses selling across Europe, Mollie's method coverage is substantially broader. You can read more about the role of digital wallets for UK merchants in our dedicated guide.

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 the 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 providers.

Integrations

Both providers connect with the major e-commerce platforms. PayPal integrates 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. Our guide to payment gateway integrations covers what to check before committing to either.

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-plus 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 its own fraud screening tools. 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. Our guide to 3D Secure and Strong Customer Authentication explains how both providers handle this requirement.

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.

Buy Now Pay Later

Both providers offer Buy Now Pay Later options. PayPal includes Pay Later directly within its Checkout button, allowing eligible UK shoppers to split purchases into three interest-free instalments with no additional integration required. Mollie integrates Klarna as one of its 25-plus payment methods, giving merchants access to Klarna's Pay Later, Pay in 3, and financing products. Klarna carries stronger brand recognition in the UK than PayPal's own Pay Later product among younger shoppers.

Pros and Cons

PayPal Pros and Cons

Pros

• Recognised by roughly 44 million UK consumers, which can improve checkout conversion rates
• Covers both online and in-person payments through Zettle hardware, starting at around £29 plus VAT
• 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 outside Europe
• Built-in Pay Later / Buy Now Pay Later option requires no additional integration

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, with no 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 £0.20 per-transaction fee still adds a noticeable amount at low average order values. At a £10 average order value, the fixed fee alone adds 2.0% to every transaction.
• Less recognisable as a brand to UK consumers than PayPal, so the payment button itself carries no direct conversion uplift
• No seller protection programme equivalent to PayPal's
• Primary regulatory licence is Dutch (De Nederlandsche Bank), not FCA-issued, which some UK businesses find less straightforward to assess

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, adding cost and complexity.

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 payment methods onto a PayPal setup. Our guide to e-commerce payment gateways explains what else to consider when choosing a gateway for cross-border selling.

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. Our payments guide for subscription and SaaS businesses covers this in more detail.

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, use the Compare Card Fees merchant services comparison tool to benchmark quotes across a wider range of acquirers.

Sole Traders and Freelancers

Both providers work for sole traders. PayPal's name recognition can reassure clients unfamiliar with online payment links, and its Pay by Link functionality is straightforward to use. Mollie's pay-by-link option suits freelancers sending invoices to European clients. For very low volumes, a few hundred pounds a month, neither provider's fees will make a material difference. The decision comes down to whether you need in-person capability (PayPal) or European payment methods (Mollie).

Effective Rate by Average Order Value

Both providers charge a fixed fee alongside their percentage fee, so both effective rates vary depending on your average order value, not just Mollie's. Mollie's UK Visa/Mastercard rate is quoted directly in GBP, so no currency conversion is needed for this table.

PayPal is cheaper per transaction at average order values below around £175. Above that threshold, Mollie's lower percentage rate starts to outweigh the fixed fee. At £200 average order value, Mollie saves around £0.16 per transaction, or roughly £160 per 1,000 transactions processed.

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 straightforward online store, PayPal's brand recognition is a genuine conversion asset, though its rate is not flat: the £0.30 fixed fee means the effective cost per transaction is higher for lower-value orders. Add 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 carefully 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 next-day settlement process make it a more predictable operational choice. The absence of any in-person product is a firm limitation, and the fixed £0.20 per-transaction element means it suits merchants with average order values of at least £25 to keep the effective rate reasonable.
