Mollie Payment Processing Review (2026): Fees, Features and Verdict

Mollie Payment Processing at a Glance

Verdict

Mollie is a credible primary processor for UK businesses with meaningful EU cross-border volume. Published per-method pricing, no monthly overhead, and native iDEAL, Bancontact, SEPA and Klarna in one integration. That combination is harder to match than it looks.

The trade-offs are real and worth knowing before you sign up. UK domestic card rates are not cleanly confirmed relative to Stripe. There is no phone support. Account holds without advance notice are the most documented operational complaint.

Settle three questions before you commit: your UK card rate, your support tolerance, and your cash-flow exposure to a potential hold. We rank the card rate first: it is the only one of the three that comes down to a figure, and Mollie doesn’t publish it for UK-issued cards.

Best For

UK direct-to-consumer and B2B e-commerce businesses with Dutch, Belgian, German or French customers. Shopify and WooCommerce merchants who need iDEAL and Bancontact at checkout to recover cross-border conversion. Subscription businesses billing EU customers via SEPA alongside UK customers via Bacs Direct Debit.

If you sell 30% of orders to Amsterdam and Rotterdam, you know how much checkout abandonment iDEAL solves. Without it, your Dutch conversion gap is typically 15–20%.

Not Ideal For

Merchants whose sales are almost entirely UK-domestic. If your volume is UK consumer cards, Stripe’s confirmed 1.5% + £0.20 may be cheaper. Also not suited to merchants who need phone escalation if a funds hold occurs.

Key Facts

Founded 2004, Amsterdam. FCA Authorised Payment Institution, ref 977968, granted 2 November 2023. De Nederlandsche Bank supervision also applies. 2025 total payment volume approximately £29.5 billion. Net revenue £125 million (2025, up 29%). Acquiring GoCardless for ~£880 million, expected mid-2026.

What Is Mollie Payment Processing?

Mollie is a payment service provider (PSP), not a bank or direct acquiring institution. It aggregates merchants under its own acquiring relationships. When a customer pays on your website, the transaction routes through Mollie’s infrastructure, settles to your Mollie balance, then sweeps to your bank account on your chosen schedule.

The company was founded in 2004 in Amsterdam and now serves approximately 250,000 businesses across Europe and the UK. It processed roughly £29.5 billion in total payment volume in 2025. Net revenue was £125 million, up 29% year on year.

For your business, that scale matters in one specific way. Mollie’s platform stability and method coverage reflect a PSP that has cleared the European SME market at significant volume, not a start-up adding methods one country at a time.

We flag the GoCardless acquisition because it changes the competitive landscape. Mollie agreed to acquire GoCardless for approximately £880 million in December 2025.

Pre-close, both companies operate independently. If you’re choosing between them today, you’re signing with the standalone entity, not the combined platform. We’ll cover the comparison in the Alternatives section.

How Does Mollie Payment Processing Work?

In the UK, Mollie operates through Mollie UK Ltd, which holds an Authorised Payment Institution licence from the Financial Conduct Authority (FCA reference 977968, granted 2 November 2023). That licence replaced the Temporary Permissions Regime Mollie had used after EU passporting rights ended with Brexit.

The Dutch parent entity, Mollie B.V., is also supervised by De Nederlandsche Bank. Your counterparty carries both Dutch and UK regulatory oversight, relevant if your compliance team is assessing whether a PSP meets your own regulatory obligations.

One consequence of the aggregator model: Mollie assesses risk at the portfolio level. If its systems flag your account (a volume spike around peak trading, elevated chargebacks, or a high-risk product category), funds can be held while a review runs.

This is a structural feature of the aggregated PSP model, not unique to Mollie. We’ll cover the practical record of how often it surfaces in the Customer Support and Reviews section.

What Payment Types Does Mollie Support?

Mollie supports 40+ payment methods across three practically meaningful tiers for UK merchants.

The first tier is universally relevant in the UK: Visa, Mastercard, American Express, Apple Pay, Google Pay, PayPal, Bacs Direct Debit, SEPA Bank Transfer and Pay by Bank. These cover the bulk of UK domestic transaction volume. We call that tier your baseline stack.

The second tier matters if your customers are in specific European markets: iDEAL (Netherlands), Bancontact (Belgium), Cartes Bancaires (France), TWINT (Switzerland), EPS (Austria), Swish (Sweden), Przelewy24 (Poland), Vipps (Norway), MobilePay (Denmark and Finland), Bizum (Spain), and Wero.

If you sell to Dutch customers without iDEAL at checkout, you lose roughly 18% of those orders at the payment step. That’s the gap these methods close.

The third tier is buy now, pay later: Klarna (Pay Later, Pay Now, Slice It), Riverty, Alma, Billie and in3. These carry higher fees than card rates and require separate activation. Availability varies by market.

How Much Does Mollie Payment Processing Cost?

Mollie publishes its transaction fees on mollie.com/pricing without requiring a quote or a sales call. That transparency is the starting point for any cost comparison: you can model your transaction costs before speaking to anyone at Mollie. We priced this review straight off that page, which most UK acquirers don’t allow.

What Are Mollie’s Transaction Fees?

Fees are set by card issuer geography and card type, not your processing volume, unless you negotiate custom rates above approximately £50,000 per month.

For consumer cards issued in the European Economic Area (EEA), Visa and Mastercard personal debit and credit cards, the rate is 1.80% + £0.21 per transaction. American Express and EEA commercial cards cost 2.90% + £0.21. Non-EEA issued cards attract 3.25% + £0.21.

Apple Pay and Google Pay are priced on the underlying card. That’s straightforward: no surcharge for wallet payments.

The UK card classification question is the most important thing to confirm before you commit. Post-Brexit, the UK is no longer part of the EEA. If Mollie classifies UK-issued cards as non-EEA, your domestic card rate is 3.25% + £0.21, materially higher than Stripe’s 1.5% + £0.20.

Third-party sources quote a distinct UK rate of 1.20% + £0.20. That may reflect a separate UK pricing schedule. Confirm in writing how your UK-issued consumer Visa and Mastercard cards are classified before signing up for UK-domestic volume.

A worked example: a £100 order at the EEA rate (1.80% + £0.21, ~£0.21) costs roughly £2.01. At Stripe’s standard UK rate (1.5% + £0.20), it costs £1.70.

Across 1,000 transactions per month, that 31p gap is £310 of margin sitting with the processor. If you’re on Shopify Plus Advanced (£259/month), run this on your volume mix before deciding. A craft retailer comparing per-method rates against a Stripe blended rate will find the same exercise useful.

Are There Monthly, Setup or Hardware Fees?

There is no setup fee, no monthly fee, no monthly minimum charge, and no lock-in contract. You pay only on successful transactions.

Payouts are included in the pricing: the first five payouts per month are free; each additional payout costs £0.21. For a merchant taking one payout per week (approximately four per month), payout fees are zero.

Volume discounts are available for merchants processing above approximately £50,000 per month. These require a direct conversation with Mollie’s sales team, not available through the self-serve dashboard.

If you bill 600 customers per month across four currencies at SEPA recurring rates, the volume discount conversation is worth initiating once you cross that threshold. We put the trigger at £600,000 in annual volume: above that, it is a routine annual review rather than a one-off.

What Other Fees Should You Watch?

Three fees sit outside the headline transaction rate and are worth building into your unit economics before you sign up.

Currency conversion: Mollie charges 1% of the payout amount when you settle in a different currency. For a UK merchant receiving euro payments and settling in GBP, this compounds quickly. Settling £8,500 per month in sterling costs roughly £85–£90 in conversion on top of transaction fees.

Refunds: Mollie does not return the original transaction fee when you issue a refund. Mollie charges €0.25 for each refund on top of that, in euros rather than sterling (help.mollie.com, checked 27 August 2026). If your product carries a 15–20% return rate, build this into your unit economics before setting your prices.

Chargebacks: a lost dispute costs you the transaction amount and a dispute fee on top. Mollie charges €25 per lost dispute, in euros rather than sterling, and only once the dispute is actually lost, not while it is open (help.mollie.com, checked 11 September 2026). The fee lands on the same balance your payouts come from. How the dispute itself runs is covered further down.

How Quickly Does Mollie Pay Out?

Mollie settles in batches rather than in real time. By default, payouts sweep to your bank account weekly on Wednesdays. You can change the schedule to daily or monthly in the dashboard settings, a useful control for businesses whose supplier payments have a specific timing requirement.

What Are Mollie’s Settlement Times?

The mechanics work in two stages. Incoming card payments settle to your Mollie balance within 1–2 business days. Then Mollie sweeps that balance to your bank on your chosen schedule.

On the default weekly payout, your funds arrive 3–5 business days after customer payment. On daily payouts, it’s closer to 2–3 days.

The first five monthly payouts are free; each additional payout beyond that costs £0.21. Daily payouts won’t break the cost model for most merchants processing reasonable volume.

If you run a weekly supplier payment run and rely on Thursday settlement to fund Friday payables, daily payouts are the setting to choose, not the default weekly Wednesday schedule. Switch it in dashboard settings before your first live transaction.

UK Bacs Direct Debit timelines sit outside this window: mandate submission and clearing follow Bacs processing cycles, which typically means 3–5 business days from collection attempt to funds in your Mollie balance.

Can Mollie Hold, Delay or Reserve Funds?

Settlement reliability is where the aggregated PSP model creates genuine operational risk. Mollie holds risk for all merchants on its platform and can freeze funds when it identifies elevated risk indicators (a spike in chargebacks, unusual transaction patterns, or unverified documentation) without prior notice.

Independent Trustpilot reviews from 2024 and 2025 include multiple accounts of merchants finding accounts frozen with no warning, unable to issue refunds, and facing slow resolution through the ticket system. The accounts are specific: merchants describe exact hold periods, inability to reach support, and funds released days or weeks later.

We read this as a documented risk, not an isolated edge case. The pattern appears consistently across reviewers who have no apparent connection.

For Klarna and other buy-now-pay-later (BNPL) methods, settlement lags are structural. Mollie waits for the BNPL provider to confirm the payment before releasing funds. The lag for Klarna can extend to several weeks.

A small fashion brand whose Klarna settlement got held for six weeks while a support ticket sat in the queue found that outcome in multiple independent reviews. If you plan to activate Klarna, budget for that lag in your cash-flow model before you go live.

If your cash flow depends on weekly settlement to cover supplier payments, model a two-week freeze as a planning variable. That’s not catastrophising: it’s in the independent review record.

What Payment Features Does Mollie Offer?

Mollie’s feature set covers three checkout paths, a range of integration options for different development budgets, and a recurring billing system that works well at scale but requires API access to unlock fully.

Does Mollie Support Online, In-Person and Remote Payments?

Hosted checkout page: Mollie generates a checkout URL your customer lands on. Card data never touches your servers, keeping your PCI scope minimal. You get all of Mollie’s payment methods in a single redirect. The trade-off: you give up checkout branding consistency.

Payment links: generate a URL or QR code tied to a specific amount. You can share it by email, WhatsApp or invoice without a full checkout integration. Issue it from the Mollie dashboard without developer resource.

API route: a fully custom checkout via Mollie’s API gives complete branding control. It requires developer resource to build and maintain. This path makes sense if you have an in-house developer or a clear product spec. For a Shopify merchant, the plugin is faster and cheaper.

What Integrations and Business Tools Are Included?

Mollie has official plugins for Shopify, WooCommerce, Magento (Adobe Commerce), PrestaShop, Shopware, Lightspeed and BigCommerce. Going from zero to live payments takes less than a day for most Shopify and WooCommerce merchants. Fast plugin setup is the most consistent positive theme across independent reviews.

Wix has some community integrations but is not in Mollie’s officially documented plugin list. Squarespace is not officially supported. On either platform, treat Mollie as unsupported until Mollie documents it.

The API is well documented, with client libraries in PHP, Node.js, Python and Ruby. Mollie Connect is a separate product that enables platforms and marketplaces to onboard sub-merchants and process payments on their behalf, relevant for SaaS companies building embedded payment flows.

Developer documentation at docs.mollie.com covers the core integration paths clearly. The depth isn’t as extensive as Stripe’s tutorial ecosystem, but it’s sufficient for most standard e-commerce use cases.

Recurring, international and advanced payments. Recurring payments are available but carry one important constraint: they require API access. The web dashboard does not expose recurring billing controls. A Shopify merchant cannot enable subscription billing through the plugin alone; they need either a subscription app that uses Mollie’s API underneath or their own API integration.

For merchants using the API, recurring works via mandates. An initial first payment establishes customer consent; subsequent charges run automatically. Failed payments are retried up to five times. Supported mandate types include credit card (including Apple Pay and Google Pay), PayPal, SEPA Direct Debit and Bacs Direct Debit.

If you run a B2B SaaS business billing 600 EU customers in four currencies (SEPA euro collections plus Bacs sterling), you can handle both mandate types through one Mollie integration. That removes the need for GoCardless for UK and a separate EU provider.

The recurring API covers retries and mandate management at SME scale without enterprise overhead. That’s the cleaner comparison against running two separate providers.

Multi-currency settlement is available at a 1% conversion fee at payout. Mollie’s geographic scope is EEA, UK and Switzerland. Coverage thins meaningfully outside that. If your customers are primarily in North America or APAC, Stripe’s 135+ currency reach is more practical.

How Does Mollie Handle Chargebacks, Disputes and Security?

Mollie holds PCI DSS Level 1 certification and ISAE3402 certification by Deloitte. All cardholder data is stored on Dutch servers, in data centres certified to international security standards. For your compliance team, those credentials confirm the baseline is met. We don’t read them as a differentiator against Stripe or Adyen on security fundamentals.

How Are Chargebacks and Disputes Managed?

When a customer disputes a charge, their bank raises a chargeback and Mollie notifies you via dashboard and email. You typically have 7–21 days (scheme-dependent) to submit evidence: invoices, customer correspondence, delivery confirmation, IP logs. Mollie acts as the intermediary; you don’t deal with Visa or Mastercard directly.

Lose the dispute and the transaction amount comes back out of your Mollie balance, along with the dispute fee set out above. That is money already counted as revenue, so the hit shows up in reconciliation rather than in your pricing.

Persistent elevated chargeback rates trigger risk reviews and can result in fund holds or account closure. The standard Visa and Mastercard threshold is 1% of monthly transaction volume.

If your product category carries a structurally higher dispute rate, model what 1% looks like at your volume. Build your evidence-collection process before the first dispute arrives, not after.

Is Mollie Secure and Compliant?

Mollie supports 3D Secure 2 across card transactions, satisfying the Strong Customer Authentication requirements under UK FCA rules. Dynamic 3DS calibrates authentication against risk signals rather than applying it universally.

Low-risk returning customers complete checkout without a challenge step. Suspicious transactions are stepped up. For your repeat billing, that reduces friction on authorisations without compromising security.

Address Verification Service (AVS) and Card Verification Value (CVV) checks apply to card-not-present transactions. Real-time behavioural analysis flags suspicious patterns. Mollie exceeds its minimum regulatory capital requirements by 300% according to its published security information.

The limitation: you cannot set custom fraud rules, velocity limits or risk thresholds in your dashboard. Fraud management runs at the platform level across the whole merchant portfolio.

We can live with that for standard e-commerce. It’s a genuine constraint for merchants in higher-fraud categories (fashion resale, digital goods, ticketing) where bespoke rules would catch patterns that generic portfolio-level scoring misses.

What Is Mollie Like to Use Day to Day?

Mollie’s dashboard is designed for merchants who manage payments themselves rather than through a dedicated finance team. It reads clearly and doesn’t require training to navigate. The trade-off is a lack of configurability at the fraud and risk layer, something merchants coming from Stripe Radar will notice quickly.

How Easy Is Mollie to Set Up?

Account creation is fully digital; most standard low-risk e-commerce businesses are approved within 48–72 hours. No sales call required to get started. We rate the self-serve sign-up one of the lower-friction onboarding flows among UK PSPs, consistently the most praised element across independent merchant reviews.

Day-to-day use is browser and mobile app-based, with no desktop software required. API credentials and webhook configuration live in the dashboard settings. The initial setup for a Shopify or WooCommerce merchant is typically completed in under a working day.

Some merchants encounter additional verification requests after going live, triggered by volume patterns or documentation gaps. These can pause account functionality until resolved. Completing KYC and KYB documentation thoroughly at sign-up reduces this risk significantly.

A UK-specific issue documented in multiple independent reviews: Mollie auto-generates an IBAN from your UK sort code and account number for settlement. Several merchants reported that this auto-generated IBAN was incorrect, causing their first settlement to fail.

Mollie has since corrected the underlying issue. But the pattern appeared consistently in 2024 reviews. Verify your settlement IBAN in the dashboard before expecting your first payout to arrive.

What Is the Dashboard or App Like?

The Insights section tracks four headline metrics (payment success rate, average transaction value, refund rate and chargeback rate) with automatic year-on-year comparison and a three-month revenue forecast. You can filter by payment method, date range and transaction status. Settlement and balance reports are exportable in standard formats.

For day-to-day reconciliation, the export tools cover what most merchants need: matching bank deposits to transaction batches, identifying refunds, and pulling method-level breakdowns for reporting.

When your accountant is preparing your VAT return and needs method-level transaction data by date, the Mollie export handles that without additional tooling. The standard fields are there; custom pivot tables aren’t required.

The gap that matters: you cannot configure custom fraud rules or set your own risk thresholds in Mollie’s dashboard. Stripe Radar and Adyen’s risk suite both expose rule-level controls. Mollie’s fraud toolset is platform-managed rather than merchant-configurable.

That’s fine for standard e-commerce. It’s a genuine limitation if your product category carries complex fraud exposure patterns.

What Do Customers Say About Mollie?

Mollie scores 4.6 out of 5 on Trustpilot across approximately 12,000 reviews, and 4.2 out of 5 on G2. We compiled this review using those profiles alongside Mollie’s published documentation and the FCA register. For a PSP at this scale, we take that as genuinely positive.

One structural fact shapes a good deal of what merchants report. Support runs through the online ticket form at help.mollie.com/hc/en-gb, with a complaints email (complaints@mollie.com) for formal escalations. We found no UK phone number for merchant support in Mollie’s own published material. The Help Center handles routine integration, payout and payment-method questions clearly enough. What it cannot do is move quickly when your money is the thing that has stopped, and that is where the review record turns.

What Do Positive Reviews Mention?

Positive reviews cluster around three consistent themes: setup speed, with Shopify and WooCommerce merchants live inside 48 hours; dashboard clarity, with settlement reports described as readable without training; and payment-method breadth in a single integration.

The onboarding praise is the most repeated of the three, and it matches what the sign-up flow actually asks of you: no sales call, published prices, a plugin you install yourself.

What Complaints Come Up Most Often?

Account holds applied without advance notice are the most common complaint, with funds inaccessible for days or weeks. A second cluster covers Klarna settlement delays: merchants waiting 6–8 weeks with a £3,400 reserve held back.

A third cluster is support responsiveness during those holds. Merchants describe ticket response times that did not match the urgency of money they could not reach. If your business needs somebody on a phone when that happens, this is the constraint to weigh, and it is a real one rather than a preference.

The incorrect auto-generated settlement IBAN described earlier also runs through the 2024 review record. Mollie has since corrected it, but check that field yourself before your first payout is due.

Who Is Mollie Payment Processing Best For?

Which Businesses Is Mollie Best Suited To?

UK direct-to-consumer and B2B merchants with European cross-border volume. If a meaningful share of your customers are Dutch, Belgian, German or French, Mollie’s native iDEAL, Bancontact, Cartes Bancaires and Klarna in one integration is the strongest argument in its favour.

A UK direct-to-consumer fashion brand shipping mostly to Amsterdam customers will see checkout abandonment drop measurably once iDEAL is live. No other mainstream processor makes that activation as straightforward. That’s the clearest reason to choose Mollie.

Shopify and WooCommerce merchants who need to be live quickly. Published pricing, no monthly fee, no sales call, plugin install in hours. If you need a checkout live this week, the barrier is low. We put that among the stronger self-serve onboarding experiences in UK payment processing.

B2B SaaS and membership businesses billing in multiple currencies. If you bill 600 EU customers in four currencies via SEPA alongside UK customers via Bacs Direct Debit, you can handle both mandate types through one Mollie integration. That removes the case for running separate providers per region.

The recurring API covers mandate management, retry logic (up to five attempts) and subscription scheduling at SME scale. We expect the combined platform to deepen that case once Mollie completes the GoCardless acquisition in mid-2026. Signing Mollie now means opting into that roadmap.

When Should You Consider an Alternative?

UK-domestic merchants with little EU cross-border volume. If your sales are predominantly UK consumer cards, Stripe’s confirmed 1.5% + £0.20 may be cheaper. Get the UK card rate confirmed in writing before committing. That classification question isn’t cleanly answered from public sources.

Merchants with primarily non-EEA international volume. Mollie’s scope is EEA, UK and Switzerland. If your customers are in North America, APAC or the Middle East at scale, Stripe’s 135+ currency reach is more practical and won’t push non-EEA volumes to the 3.25% + £0.21 tier.

Merchants where phone escalation is a hard requirement. Mollie doesn’t offer a UK phone support line. If your business relies on immediate escalation when funds are frozen, ticket-based resolution won’t give you what you need. That’s a real constraint, not a preference.

High-volume merchants where interchange-plus pricing unlocks savings. Above approximately £2 million in annual processing, Adyen’s interchange-plus model starts to undercut Mollie’s flat rates. The £100/month minimum and enterprise onboarding overhead become proportionate at that volume.

What Are the Best Alternatives to Mollie Payment Processing?

Mollie vs Stripe

Stripe is the closest competitor for UK online merchants. On UK domestic consumer card volume, Stripe’s 1.5% + £0.20 is likely lower than Mollie’s EEA consumer rate (1.80% + £0.21), assuming UK-issued cards are treated as EEA by Mollie, which isn’t publicly confirmed.

If you process £20,000/month in UK consumer card payments, the difference at those rates is approximately £60–£70 per month. That’s a concrete number to run before committing to either processor.

Mollie’s advantage is European method depth: iDEAL, Bancontact and regional BNPL without API custom work. If you have a significant Dutch or Belgian customer base, Mollie is better architected for that mix.

On developer tooling, Mollie’s API covers payments and recurring mandates cleanly. It lacks Stripe’s Billing, Radar and Connect for complex payment architectures. That’s the trade-off.

On the published rates we compared, the split is simple: if your primary volume is UK-domestic consumer cards, start with Stripe. If your primary case is European cross-border and local methods, Mollie is the more practical default.

Mollie vs GoCardless

This comparison changed materially in December 2025 when Mollie agreed to acquire GoCardless for approximately £880 million. The deal was pending regulatory approval as of May 2026, with a mid-2026 close expected. If you’re choosing between them today, you’re signing with the standalone entity before the integration exists.

On a like-for-like basis, GoCardless is purpose-built for Direct Debit and open banking, starting at 1% + £0.20 for standard UK Bacs payments. It excels where low payment failure rates and mandate management matter more than card breadth. Mollie is card-and-method-led. Direct Debit is one element, not the core.

If more than 70% of your billing runs through Direct Debit (a B2B subscription business charging EU customers via SEPA, or a UK membership organisation collecting via Bacs), GoCardless is the cleaner fit on failure-rate handling and mandate management today.

If cards and local methods carry your volume, Mollie is the more practical primary processor. We recommend modelling your actual method split before deciding, rather than treating the two as interchangeable.

Visit GoCardless →

Mollie vs Adyen

Adyen operates at a meaningfully different tier. Interchange-plus (IC++) pricing passes actual interchange and scheme fees through with a fixed processor margin, giving your finance team full cost visibility. That’s an advantage over Mollie’s flat blended rates once your volume is large enough to see the difference.

Adyen also brings a unified platform across online and in-person acquiring, global reach across 150+ currencies, and advanced risk tooling. The practical constraint is minimum volume: a minimum monthly invoice of approximately £100, with enterprise onboarding. Onboarding runs to weeks, not hours.

For most businesses processing under £2 million annually, the IC++ savings don’t yet justify that overhead. We rate Adyen a growth destination rather than a direct Mollie competitor at SME scale.

Mollie suits the £0–£2 million annual processing band cleanly. Above that, every incremental improvement in your card authorisation rate starts to pay for the switch. That’s when you should run the Adyen cost comparison seriously.

Final Verdict: Is Mollie Payment Processing Worth It?

Mollie is an FCA Authorised Payment Institution, Dutch-regulated, with published per-method pricing and £29.5 billion in 2025 payment volume. For UK merchants with buyers in the Netherlands, Belgium, Germany and France, it offers the widest European local method coverage of any mainstream PSP in a single integration.

The fee structure is the clearest positive. No setup cost, no monthly fee, no minimum volume. Published rates before you speak to anyone. That’s an uncommon baseline in payment processing. It’s the first thing to compare against your current processor’s cost model.

Three constraints are worth stating plainly. First, we could not confirm the UK domestic card rate from Mollie’s own pricing page. If your volume is UK-consumer-card-heavy, get that rate in writing before committing. Second, there is no phone support.

Third, account holds without advance notice are documented extensively in independent reviews. The aggregator model carries that structural risk regardless of how well your business performs. That’s the honest frame for this review.

The GoCardless acquisition (expected mid-2026) points Mollie toward a more complete UK proposition. Post-close, the combined platform will offer card, local method and Direct Debit depth under one contract. That integration isn’t live yet. We treat it as a roadmap item, not a current feature.

For the right merchant (EU-facing, e-commerce-led, cost-sensitive on monthly overhead, comfortable with online-only support), Mollie is a credible primary processor. For UK-domestic-only merchants, or anyone whose operations can’t absorb a multi-week funds freeze, start the comparison with Stripe.
