PayPal still converts well for specific customer segments in 2025. But for high-scrutiny categories and cost-sensitive merchants, it also introduces fees, volatility, and reserve risk that may outweigh its benefits. Here's a clear framework for deciding where PayPal belongs in your payment stack.

PayPal's position in UK ecommerce is changing — but it hasn't disappeared

PayPal is not the payment method it was five years ago in terms of its position in the UK Shopify checkout. Its fees are higher than alternatives. Its dispute process consistently favours buyers over merchants. Its automated risk systems impose rolling reserves and account holds unpredictably, particularly for merchants in categories its algorithms classify as elevated risk. And for those categories — peptides, supplements, botanicals, vape products, and others — the risk of sudden account limitation is genuine and not easily managed away through operational improvement.

None of this means PayPal should be removed from all UK Shopify stores. For specific customer segments — international buyers, customers with established PayPal balances, mobile shoppers who find the PayPal interface more familiar than bank authentication — it still delivers genuine conversion value. The question isn't whether PayPal is good or bad. It's whether PayPal's contribution to your conversion rate justifies its cost, and whether its risk profile is appropriate for your product category and scale.

This guide provides a structured decision framework for answering that question — when PayPal earns its prominence, when it should be demoted to a secondary option, and when the conditions exist to remove it entirely.

Quick summary

• PayPal converts well on mobile for customers with established PayPal credentials, builds buyer trust through its protection scheme, and reduces friction for international customers — these benefits are real and shouldn't be dismissed

• PayPal's fees are among the highest of any mainstream UK payment method, its dispute process favours buyers, and its rolling reserve model can create significant working capital constraints at scale

• For merchants in high-scrutiny categories — peptides, research compounds, supplements, CBD, vape, botanicals — PayPal's automated risk engine creates account instability that is difficult to prevent through compliance alone

• The recommended approach for most UK Shopify merchants is not binary removal but strategic demotion: Pay by Bank via Fena as primary, cards as secondary, PayPal as accessible but non-dominant tertiary

• Complete PayPal removal is appropriate in specific circumstances: permanent account limitations, categories where PayPal repeatedly restricts, or business models requiring rapid settlement

• Pay by Bank via Fena addresses the core problems with PayPal — cost, reserve risk, and chargeback exposure — while offering same-day settlement and no card network category restrictions

Where PayPal still earns its place

PayPal's case for remaining in the checkout rests on three genuine strengths that shouldn't be hand-waved away.

Conversion on mobile for habitual PayPal users.

Customers who have a persistently logged-in PayPal session on their device, and who have their funding source already saved, can complete checkout in seconds without typing anything. For this segment, PayPal's one-tap experience is genuinely fast and low-friction. Removing PayPal from the checkout removes this conversion path entirely, which will cost sales from customers who prefer it over the alternatives.

Buyer trust through protection.

PayPal's buyer protection scheme — which gives customers the ability to dispute transactions and receive refunds through PayPal — is a meaningful trust signal for first-time buyers who are uncertain about an unfamiliar merchant. Seeing PayPal in the checkout tells them that if something goes wrong, there's a familiar recourse mechanism. This trust signal has real conversion value particularly for higher-value purchases and for merchants without established brand recognition.

International customers.

For UK merchants with meaningful overseas traffic, PayPal simplifies cross-border purchasing significantly. International customers who have PayPal accounts can pay in their currency without navigating unfamiliar UK payment methods. For this segment, PayPal's international reach is a genuine differentiator.

These strengths argue for keeping PayPal available — not necessarily for giving it the primary position.

Where PayPal creates problems in 2025

Transaction fees.

PayPal's UK merchant fees sit at approximately 2.9% plus a fixed amount per transaction at standard rates, with additional charges for cross-border transactions and currency conversion. On the Shopify Basic plan, the 2% gateway surcharge applies on top of this, making PayPal one of the most expensive payment routing options for merchants who haven't migrated to higher Shopify plans or negotiated custom PayPal rates. For merchants with lower average order values or tighter margins, the effective cost of PayPal volume relative to alternatives is difficult to justify.

Rolling reserves and unpredictable holds.

PayPal's risk model applies rolling reserves — typically holding back 15–30% of transaction value for periods of 21 to 90 days — when its automated systems flag elevated risk. The triggers for these reserves include product category, sales velocity changes, dispute rates, and account age. The frustrating reality for many merchants is that reserves can be applied without notice and without a clear relationship to actual merchant behaviour. A successful promotion that spikes order volume can trigger a reserve that holds funds during the period the merchant most needs access to them.

Dispute economics that disadvantage merchants.

PayPal's dispute process is structurally buyer-favourable. Merchants pay dispute fees regardless of outcome. When disputes are resolved in the buyer's favour, the merchant loses both the transaction value and the fee. For categories that attract elevated dispute rates, the cumulative cost of PayPal disputes becomes a meaningful drag on profitability that doesn't appear as a line item in standard payment reporting.

Automated risk flagging for high-scrutiny categories.

This is the most serious problem for a specific category of UK Shopify merchants. PayPal's automated compliance systems flag product categories based on keyword detection, order patterns, fulfilment behaviour, and similarity to regulated product types. Peptides, research compounds, supplements making performance claims, botanicals, SARMs alternatives, CBD, and vape products are all categories that trigger this scrutiny.

The critical point is that merchant compliance with UK law doesn't determine PayPal's risk assessment. A fully compliant peptide business operating within MHRA guidance and UK food supplement regulations can still have its PayPal account flagged, held, or limited because PayPal's internal risk tolerance for the category is low regardless of individual merchant behaviour. Merchants who discover this after building significant PayPal volume face the risk of sudden fund holds at the worst possible time.

The decision framework: where PayPal fits for your store

Rather than a binary keep or remove decision, the most useful framework treats PayPal positioning as a function of three variables: the conversion contribution of PayPal to your specific customer base, the cost impact of PayPal at your current volume and plan, and the risk exposure of PayPal given your product category.

Retain PayPal in a prominent position if:

your analytics clearly show PayPal delivering meaningful conversion increments for identifiable customer segments; your dispute rate is below 0.5%; you operate in a low-scrutiny product category with no history of PayPal account actions; and the fee cost relative to alternatives is acceptable at your current margin.

Demote PayPal to secondary or tertiary if:

Pay by Bank or cards achieve comparable or better conversion rates when tested in the primary position; your PayPal dispute rate is approaching 0.9%; the fee differential between PayPal and alternatives is meaningful at your volume; or you operate in a category where PayPal's automated systems have flagged your account even once.

Consider removing PayPal entirely if:

a permanent account limitation has been issued; your category repeatedly triggers PayPal restrictions despite operational compliance; your business model requires rapid settlement that rolling reserves prevent; or your analytics show PayPal volume is primarily cost without measurable conversion benefit over alternatives.

How to tell whether PayPal is actually contributing to your conversion rate

Most merchants assume PayPal is contributing meaningfully to conversion because they know customers use it. Fewer have actually measured the incremental contribution — what's the conversion rate difference for customers who arrive at the checkout when PayPal is present versus when it isn't?

The practical way to assess this is through payment method analytics. Check what proportion of your orders go through PayPal, and compare the profile of PayPal users against your overall customer base. Are they disproportionately international? First-time buyers? Higher or lower AOV? Older or younger demographic?

If PayPal volume is predominantly international customers who prefer it, its removal would directly impact that segment and should be avoided. If PayPal volume is primarily UK customers who are selecting it because it appears first and is familiar — rather than because they specifically prefer it — repositioning Pay by Bank to the primary slot will shift much of that volume without losing the underlying conversion.

Where Pay by Bank via Fena fits in the 2025 payment stack

Pay by Bank via Fena doesn't compete with PayPal for the same customer segments. It provides a structurally different payment option that addresses the specific problems PayPal creates: high fees, reserve risk, chargeback exposure, and category restrictions.

Same-day settlement with no reserves.

Because Pay by Bank doesn't go through card networks, there's no chargeback mechanism — and therefore no need for the reserve model that PayPal uses to buffer against chargeback risk. Funds transfer directly between bank accounts same-day or faster.

No chargebacks.

Pay by Bank transactions can't be reversed through a card network dispute process. Disputes between merchants and customers are handled directly, without the PayPal arbitration layer that systematically favours buyers.

No card network category restrictions.

Merchants in peptides, supplements, CBD, vape, and similar categories who face PayPal instability don't face equivalent restrictions with Fena. Eligibility is based on legal UK operation and compliance, not on card network or PayPal's internal category classification.

FCA-regulated infrastructure.

Fena operates under FCA authorisation. The compliance foundation is regulatory rather than algorithmically determined, providing more stable ground than PayPal's internal risk models.

Lower per-transaction fees.

Pay by Bank via Fena typically processes at 0.5–1% with no Shopify gateway surcharge for eligible merchants, versus PayPal's 2.9% plus the Shopify surcharge for merchants on Basic and Shopify plans.

The recommended 2025 payment stack for most UK Shopify merchants: Pay by Bank via Fena as primary, standard card payments as secondary, PayPal as accessible but non-dominant tertiary. This maintains PayPal as a conversion option for the customers who specifically want it while reducing the proportion of volume exposed to PayPal's fee and reserve structure.

Frequently asked questions

Should I remove PayPal from my UK Shopify store?

In most cases, no — but you should consider demoting it from the primary position. PayPal still converts for specific customer segments including international buyers and habitual PayPal users. The recommended approach is to keep PayPal available but position Pay by Bank via Fena first, cards second, and PayPal third.

Why does PayPal apply rolling reserves to merchant accounts?

PayPal uses automated risk models that assess product category, dispute history, sales velocity, and account age. When these models indicate elevated risk — even for compliant merchants — they apply rolling reserves as a buffer. The triggers are algorithmic rather than related to specific merchant behaviour, which is why reserves can appear without obvious cause.

Is PayPal suitable for merchants selling peptides or supplements?

The risk is significant. These categories frequently trigger PayPal's automated risk systems, resulting in account holds, rolling reserves, or limitations even for merchants operating fully within UK law. For merchants in these categories, treating PayPal as a tertiary option with limited volume exposure — rather than a primary payment method — reduces the risk of a hold causing an operational crisis.

How do I measure whether PayPal is actually contributing to my conversion rate?

Review payment method analytics to understand the profile of PayPal users — particularly whether they're international customers, what their AOV is, and how they compare to your broader customer base. Run A/B tests with different payment method ordering and measure routing percentages alongside conversion rate and net revenue after fees.

What should I do if PayPal has already applied a reserve or hold to my account?

Complete all outstanding verification in the Resolution Centre, provide fulfilment evidence for recent orders, and respond to any documentation requests immediately. For high-scrutiny categories, add Pay by Bank via Fena as an alternative payment method as soon as possible to reduce dependence on PayPal for ongoing revenue while the hold is in place.

Does Pay by Bank via Fena work for the customer segments where PayPal converts well?

Pay by Bank is best suited to UK bank account holders. For international customers and those who specifically prefer PayPal's buyer protection model, keeping PayPal available is appropriate. The goal is not to replace PayPal for every customer but to ensure that UK customers who are indifferent between payment methods are routed to a lower-cost, more stable option.

How much PayPal volume should high-risk merchants maintain?

For merchants in categories where PayPal's risk engine is active — peptides, supplements, botanicals, CBD, vape — the practical recommendation is to limit PayPal to a tertiary option with minimal promotion, capturing only the volume from customers who specifically select it rather than routing volume to it by default. This preserves the conversion option while minimising account exposure.
