Mollie Payments UK Review 2026: Fees, Features and Honest Verdict

Mollie is a European payment service provider founded in Amsterdam in 2004 that has grown into one of the continent's most widely used payment gateways for ecommerce businesses. In the UK, Mollie offers online card processing, a hosted payment gateway, and support for over 30 payment methods including Apple Pay, Google Pay, Klarna, and PayPal. Transaction fees start at 1.8% plus 0.25p for UK and European personal Visa and Mastercard cards, with no monthly fees, no setup costs, and no minimum contract. It is a strong fit for small to medium-sized online retailers, but it offers no card terminals for in-person payments, which rules it out for any business needing face-to-face processing.

Key Facts: Mollie UK

Who Is Mollie For?

Mollie is built primarily for online businesses. It suits ecommerce retailers, subscription services, SaaS companies, and digital product sellers that need a straightforward payment gateway without the overhead of a traditional merchant account. If your customers pay you online, and you want to accept cards, bank transfers, and alternative payment methods from a single integration, Mollie is worth a serious look.

The platform is particularly well suited to businesses selling into Europe. Mollie supports iDEAL, Bancontact, SOFORT, and other local European payment methods out of the box, which makes it one of the easier choices for UK merchants with a significant European customer base. Businesses processing over £100,000 a month may find that interchange-plus pricing from a provider like Adyen or Stripe works out cheaper.

Mollie is not a good fit for bricks-and-mortar retailers, market traders, or hospitality businesses. It has no card machine offering. If you need face-to-face payments as well as online, you will need to look elsewhere, at providers like Square or SumUp that cover both channels.

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 takes PCI compliance burden off your plate 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.
• 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. Not available to all merchants and subject to eligibility.

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 the total cost easy to forecast, and it means low-volume businesses are not penalised during quiet months.

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.

Refunds do not cost you extra in terms of the 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.

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 channel is 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 while accounts are reviewed, which can disrupt cash flow with little warning.

Mollie vs Stripe: A Quick 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, though.

Stripe's standard UK card rate of 1.5% + 20p is lower than Mollie's 1.8% + £0.25. On a £50 transaction, Stripe costs 95p versus Mollie's £1.15. 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.

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.
