Mollie Payments UK: Processing Costs and Feature Breakdown

Mollie is a European payment service provider founded in Amsterdam in 2004, and one of the most widely used online payment gateways for UK ecommerce businesses. In the UK, Mollie offers card processing, a hosted checkout page, and over 30 payment methods including Apple Pay, Google Pay, Klarna, iDEAL, and PayPal. Transaction fees start at 1.20% plus £0.20 per transaction for UK personal Visa and Mastercard cards. There is no monthly fee, no setup cost, and no minimum contract. Mollie is a strong fit for small to medium-sized online retailers, particularly those selling into Europe. It has no card terminal product, so any business that needs face-to-face payments will need a separate provider.

What Is Mollie?

Mollie is a payment service provider that processes online card payments and alternative payment methods for businesses across Europe and the UK. Founded in Amsterdam in 2004, it now serves over 250,000 businesses across Europe. In the UK, it operates as an online-only payment gateway. You cannot use Mollie to accept payments in person. The platform connects to your website or ecommerce platform and handles payment processing, fraud screening, and settlement on your behalf.

Mollie is regulated as an Electronic Money Institution. Mollie B.V. holds authorisation from De Nederlandsche Bank, and its Irish entity is licensed by the Central Bank of Ireland. Customer funds are held in segregated safeguarding accounts, as required under Electronic Money Regulations. This structure is standard for payment service providers of this type.

Mollie Features

• 30+ payment methods in one integration: Accept Visa, Mastercard, American Express, Apple Pay, Google Pay, PayPal, Klarna, iDEAL, Bancontact, SOFORT, and more through a single API or plugin.
• Hosted checkout page: Mollie provides a pre-built, customisable checkout hosted on its own servers, which removes the PCI compliance burden for the payment page itself.
• Platform plugins: Ready-built integrations for WooCommerce, Shopify, Magento, PrestaShop, and Wix mean most ecommerce merchants can connect Mollie without writing code.
• Recurring payments and subscriptions: The Mollie API supports recurring billing and tokenised card storage, useful for subscription box businesses and SaaS products.
• Mollie Dashboard: A web-based dashboard lets you monitor transactions, issue refunds, generate payment links, and view settlement reports in one place.
• Pay by link: Generate a payment link without a full ecommerce integration, useful for invoicing, deposits, or phone orders where a customer pays online later. See the pay by link guide for more context on this payment method.
• Multi-currency support: Accept payments in euros, pounds sterling, and a range of other currencies, with settlements available in GBP.
• Mollie Capital: A revenue-based lending product that advances cash against your transaction history, repaid automatically as a percentage of daily sales. Eligibility is not guaranteed and availability varies by merchant.

Mollie Fees and Pricing

Mollie uses a pay-as-you-go, per-transaction pricing model. There is no monthly subscription, no setup fee, and no minimum processing volume. You pay only when you take a payment. This makes costs easy to forecast during quiet months, which suits seasonal businesses and early-stage startups.

At £10,000 of monthly card volume on UK consumer Visa and Mastercard cards, Mollie's fees work out at roughly £180 in percentage fees plus around £25 in fixed per-transaction fees, assuming an average transaction value of £50 and 200 orders. That is approximately £205 per month in total processing costs, with nothing added for account maintenance. At higher volumes, say £50,000 per month, the percentage element alone reaches £900, at which point negotiated interchange-plus pricing from a larger acquirer often becomes more competitive. For a clear explanation of why that matters, read the interchange-plus vs blended pricing guide.

Refunds do not carry an extra fixed fee, but Mollie does not return the original transaction fee when a refund is processed. That is consistent with most UK payment providers, but it is worth factoring in if your return rate is high. For more on how payment processing fees are structured, see the merchant account fees explained guide.

Mollie Pros and Cons

Pros

• No monthly fees or setup costs: You pay nothing until you take a payment, which suits seasonal businesses and startups.
• Wide range of payment methods: Over 30 methods in a single integration means fewer third-party tools and less friction at checkout.
• Strong European coverage: Local payment methods like iDEAL and Bancontact are built in, not bolted on, which is a genuine advantage for UK merchants selling to European customers.
• Fast to set up: Most merchants can have a live account and working integration within one to two business days.
• Plugin library: Pre-built connectors for the major ecommerce platforms mean you do not need a developer for a standard setup.

Cons

• No card machines or in-person payment support: Mollie is online only. If your business needs face-to-face payments, you will need a separate provider entirely.
• Two-day settlement: Funds typically arrive two business days after a transaction, which is slower than providers like Dojo, which settles next business day. For cash-flow-sensitive businesses, this gap matters.
• Blended pricing at higher volumes: Mollie's flat-rate model becomes expensive as volume grows. A business processing £100,000 a month on UK cards pays around £1,825 in percentage fees alone, before fixed costs. Interchange-plus pricing is not currently offered to most UK merchants.
• Phone support is limited: Mollie's primary support channels are email and live chat. Businesses that need to speak to someone quickly during a payment outage may find this frustrating.
• Account holds and reviews do occur: Like most payment service providers, Mollie uses automated risk monitoring. Some merchants report temporary holds on payouts whilst accounts are under review, which can disrupt cash flow with little warning.

Mollie vs Stripe: A Direct Comparison

Mollie and Stripe are the two European ecommerce payment gateways that UK online businesses most commonly compare. Both use per-transaction pricing with no monthly fee, and both support a broad range of payment methods. The differences are meaningful.

Mollie's UK rate of 1.20% plus £0.20 is lower than Stripe's standard 1.5% plus 20p. On a £50 transaction, Mollie costs 80p versus Stripe's 95p. That difference compounds quickly at volume. Mollie's advantage is its depth of European local payment method support and a simpler dashboard that some non-technical merchants find easier to use day to day. For full details on Stripe's UK pricing and features, see the Stripe UK review. For a full head-to-head breakdown, the Stripe vs Mollie comparison covers both providers in detail.

Mollie vs PayPal for UK Merchants

PayPal and Mollie are both online-only payment options with no monthly fees, but they serve different purposes. PayPal is primarily a consumer wallet that businesses can accept as a payment method. Mollie is a full payment gateway that handles card processing, bank transfers, and alternative payment methods including PayPal as one option within its checkout.

For a UK merchant building an ecommerce checkout from scratch, Mollie gives you broader payment method coverage from a single integration. PayPal's standard transaction fee for UK merchants is 2.9% plus a £0.30 fixed fee for card transactions, higher than Mollie's rate (1.20% plus £0.20), and PayPal does not include iDEAL, Bancontact, or Klarna natively. The PayPal vs Mollie comparison covers this in more depth.

What Is Stichting Mollie Payments?

Stichting Mollie Payments is a Dutch foundation (stichting means foundation in Dutch) that holds customer funds on behalf of Mollie B.V. as part of Mollie's regulatory safeguarding obligations. Under Electronic Money Institution rules, Mollie is required to keep merchant funds separate from its own operating funds. Stichting Mollie Payments is the legal entity that holds those segregated funds. If you see this name on a bank statement or in a transaction reference, it is Mollie's fund safeguarding structure and not a separate business.

Is Mollie Right for Your Business?

Mollie is a credible, well-established payment gateway for UK ecommerce businesses, particularly those with European customers or those that need to offer alternative payment methods alongside cards. The no-contract, no-monthly-fee structure keeps it accessible for growing businesses. The two-day settlement and blended pricing model are the most common reasons merchants eventually look elsewhere as they scale.

If you are purely an online retailer processing under £50,000 a month and you sell to European customers, Mollie is one of the more sensible choices available. Beyond that threshold, the maths starts to favour providers that offer interchange-plus pricing. It is also worth checking whether Klarna's own direct integration might suit you better than Mollie's Klarna connection, depending on how central buy now, pay later is to your checkout strategy. The buy now pay later guide for UK merchants explains the options clearly.
