PayPal vs Stripe: Which Is Right for Your UK Business?

PayPal and Stripe are the two most recognised payment platforms in the UK, and they’re frequently compared as alternatives. For most businesses, they’re actually complements rather than alternatives — Stripe for the payment infrastructure, PayPal as an additional option for customers who prefer it. But there are use cases where one is clearly better than the other, and use cases where you genuinely only need one. This guide covers the practical differences, fee comparison, and when each is the right choice.

What they actually do

Both accept card payments and both allow customers to pay online. That’s where the similarity ends.

Stripe is a developer-first payment infrastructure platform. Card payments, subscriptions, marketplace payments, fraud prevention, financial services — Stripe’s API covers all of it. The developer experience is excellent, the documentation is comprehensive, and it’s the default choice for most SaaS, ecommerce and fintech businesses. Customers pay by entering their card details — they don’t need a Stripe account.

PayPal is a consumer wallet that also functions as a payment gateway. Customers pay using their stored PayPal balance or a card linked to their PayPal account. They authenticate with their PayPal credentials rather than entering a card number. PayPal also accepts card payments from non-PayPal customers, but its primary identity is as a trusted consumer payment brand — the “Pay with PayPal” button customers have been clicking for twenty years.

Fee comparison

Stripe UK standard rates: 1.5% + 20p for European cards, 2.9% + 30p for non-European cards. No monthly fee on the standard plan.

PayPal UK standard rates: 2.99% + 49p per transaction for PayPal wallet payments. Higher than Stripe for most transaction values.

For a £50 transaction: Stripe costs 95p, PayPal costs £1.99. For a £100 transaction: Stripe costs £1.70, PayPal costs £3.48. The gap is meaningful at volume — for a business processing £50,000 per month, the difference between Stripe and PayPal fees is thousands of pounds per year.

PayPal offers lower rates on higher volumes and through negotiated merchant rates, but the standard rates are significantly higher than Stripe. For card payments specifically, Stripe is cheaper for most UK businesses.

Checkout experience

Stripe presents a card input form (via Stripe Elements or Payment Element) or redirects to Stripe Checkout. Customers enter their card details. Stripe handles 3D Secure authentication where required. The experience is smooth and familiar for card users. No account required.

PayPal opens a popup or redirect to PayPal’s own login and payment flow. Customers log in to their PayPal account and approve the payment. For customers who use PayPal regularly, this is fast and familiar — their payment details are already stored, they just approve. For customers who don’t have PayPal or don’t remember their credentials, it’s additional friction.

The checkout experience is where the demographic difference matters most. Younger, tech-comfortable buyers often prefer card entry. Older buyers, eBay-native buyers, and anyone who’s been using PayPal as their primary online payment method often specifically look for the PayPal button and trust it more than entering a card on an unfamiliar site.

Developer experience

Stripe has the best developer documentation in the payments industry. The API is consistent, well-designed and thoroughly documented. Webhooks are reliable. The testing environment is excellent. Building on Stripe is straightforward for any developer familiar with REST APIs.

PayPal has improved significantly but still lags behind Stripe for developer experience. The documentation covers multiple generations of APIs (old Express Checkout, newer Orders API, various SDK versions) which creates confusion about which approach to use. The sandbox can be slower than production. Some edge cases and error states are poorly documented. PayPal integrations typically take longer to build and test than equivalent Stripe integrations.

Recurring subscriptions

Stripe Billing is the gold standard for subscription management — trial periods, proration, plan upgrades and downgrades, dunning, customer portal. For SaaS businesses, Stripe Billing is usually the first choice.

PayPal Subscriptions (Billing Plans) works well for recurring billing but has less flexibility than Stripe. The main reason to use PayPal subscriptions rather than Stripe is when your customer base specifically wants to pay subscriptions via PayPal — some demographics strongly prefer to manage all recurring payments through PayPal rather than leaving card details with individual merchants.

Payouts — paying people out

Stripe Connect handles marketplace payouts to connected accounts. The setup is complex but comprehensive — onboarding sellers, handling KYC, splitting payments and paying out. For large marketplace platforms this is the right infrastructure. Stripe Instant Payouts to debit cards is also available.

PayPal Payouts API sends money to PayPal accounts. Simpler to set up than Stripe Connect, works well when recipients have PayPal accounts and want PayPal payments. The 2% fee capped at £1 makes it reasonably cost-effective for higher-value payouts but expensive for low-value high-volume disbursements.

Revolut Business API sends to UK bank accounts directly — no PayPal account required, lower per-transaction costs for higher volumes. For trade-in businesses, contractor platforms and any use case where recipients prefer bank transfer, see the Revolut Business API integration.

When to use Stripe only

Stripe only makes sense when: your customer base is predominantly tech-comfortable and comfortable with card entry; you don’t have a segment that specifically wants PayPal; you’re building a SaaS or subscription platform where Stripe Billing is the better recurring billing solution; or you want to minimise integration complexity.

When to use PayPal only

PayPal only makes sense when: your customers are primarily PayPal users (marketplace sellers, eBay ecosystem); you need to pay recipients who want PayPal; or you’re operating in a market where PayPal is dominant and card alternatives aren’t expected.

When to use both

Both together is the most common answer for UK ecommerce businesses. Stripe as the primary card payment option, PayPal as the “Pay with PayPal” button. Customers who prefer card use Stripe. Customers who prefer PayPal use PayPal. Checkout conversion improves because no customer is forced to use a payment method they don’t prefer. The additional integration cost for adding PayPal alongside an existing Stripe integration is the main barrier — worth doing when the expected PayPal checkout usage justifies it.

Integration complexity comparison

Stripe integrations are generally faster to build. The API design is consistent, error messages are clear, and the documentation covers edge cases well. A Stripe checkout integration, webhooks and subscription management can be built and tested in a week. Stripe’s developer tooling (the Stripe CLI for local webhook testing, the Stripe Dashboard for event inspection) makes debugging straightforward.

PayPal integrations take longer for equivalent functionality. The documentation covers multiple API generations simultaneously, which creates ambiguity about the right approach. The sandbox can behave differently from production in minor ways that only become apparent during live testing. PayPal’s error handling is less consistent than Stripe’s, requiring more defensive code. An equivalent PayPal checkout integration typically takes 20–40% longer than a Stripe integration.

This integration complexity difference is reflected in the relative pricing. A PayPal integration costs more to build than the equivalent Stripe integration not because PayPal is more powerful, but because it takes more time to implement correctly. The cost difference is not large in absolute terms but is worth understanding when budgeting.

3D Secure and payment authentication

Both Stripe and PayPal handle 3D Secure (3DS) authentication for card payments. Stripe’s Payment Element handles 3DS automatically and transparently — when a card requires 3DS authentication, the customer completes it within the Stripe checkout flow without being redirected away. PayPal also handles 3DS for card payments, but the implementation is less seamless for non-PayPal card payments.

For Stripe, the 3DS handling is one of the integration’s strong points — it just works, the conversion impact is minimised, and the integration doesn’t need to handle 3DS edge cases explicitly. For PayPal, the 3DS experience for non-PayPal card payments (via Advanced Checkout) requires additional implementation care.
