How to compare payment gateways for your Shopify store

Choosing the right payment gateway determines your checkout conversion, transaction costs and customer experience. Here's exactly how to compare Stripe, PayPal, Shopify Payments, Adyen and other Shopify payment gateways.

CartDNA connects to your current payment stack. You can use your existing gateway and unlock more local payment methods without switching processors or integrating a new core provider.

Why your payment gateway choice matters

Your payment gateway isn't just a transaction tool — it's part of your conversion strategy. The right gateway helps you increase sales. The wrong one increases fees, blocks international markets and frustrates customers.

Checkout conversion

High transaction fees and unclear checkout experiences lead to abandonment. Modern gateways must minimise friction, support local methods and be recognised as trustworthy.

Settlement speed

Fast settlements improve cashflow. Delays can affect refunds, restocking and operational cashflow.

Implementation flexibility

Some gateways require complex setup; others work immediately. If you're on Shopify, look for native connections that don't require custom code.

Geographic reach

Selling internationally means supporting local payment methods customers actually use, not just global credit cards. Don't let a gateway stop you expanding into new markets.

1. Compare fees and pricing

Transaction fees add up quickly. Even a 0.2% difference between gateways can represent thousands in revenue. The devil's in the details.

What to compare

Transaction rates

Example: Shopify Payments (2.9% + 30p UK), Stripe (2.9% + 30p), PayPal (2.99% + fixed). Minor differences become significant at high volume.

International settlement fees

If you sell globally, currency conversion and cross-border settlement fees count. Some gateways charge 1-2% more for foreign transactions.

Transfer and payout fees

Some gateways charge you to withdraw funds. Check payout speed too — faster payouts improve cashflow.

Dispute fees

Chargeback and dispute fees vary significantly. Some providers charge £15-25 per chargeback, whether you win or lose.

Subscription and integration fees

Some premium gateways (like Adyen) require monthly fees on top of transaction fees. Evaluate whether the cost aligns with your needs.

Why it matters

A shop processing £100,000/month at 3% pays £3,000/month in fees. At 2.7%, it's £2,700. Over a year, that's £3,600 difference — enough to hire customer support or invest in adverts.

💡 Pro tip: Consider the full picture, not just listed rates. Some gateways offer lower rates but restrict you to credit cards only. If you miss local conversion (Bancontact, iDEAL, Klarna), you lose more revenue than you save on fees.

2. Compare checkout user experience (UX)

Fees matter, but if your gateway creates friction at checkout, you lose customers. The checkout experience determines conversion.

What matters to buyers

Checkout speed (fewer steps = more conversions)
Familiar payment methods (don't force buyers onto unknown options)
Visual trust (brand logos, clear security badges)
Mobile-first UI (most ecommerce traffic is mobile)
Clear language support

Questions to ask

  • Does the gateway support one-page checkout?
  • Does it require customers to leave your shop to complete checkout?
  • Can you customise the checkout appearance to match your brand?
  • Are fees and currencies displayed clearly before payment confirmation?
  • Is the experience optimised for mobile?

UX differences examples

Stripe:Highly customisable, modern UI, embedded checkout
PayPal:Redirects to PayPal for login (friction if not already logged in)
Square:Simple checkout, optimised for B2C/retail
Adyen:Enterprise-level, supports local payments, flexible API

3. Compare global and regional support

If you sell internationally, your customers expect local payment options. Credit cards aren't enough. Local payment methods dramatically increase conversion in some regions.

Why local payment support matters

Better conversion

Buyers like to pay with methods they know

Less abandonment

If their preferred method isn't available, they leave

Local compliance

Some regions like India require local methods

Credibility

Displaying Bancontact in Belgium signals you're serious

Regional examples

EuropeStripe, Adyen, PayPal support iDEAL (NL), Bancontact (BE), Klarna (Nordic EU), SEPA
UKGateways must support Apple Pay, Google Pay, Klarna UK
Asia-PacificAlipay, WeChat Pay (China), GrabPay (SEA), PayNow (Singapore)
GlobalAdyen and Stripe offer the widest reach; Shopify Payments is US/CA/UK outside other limited regions

💡 Pro tip: Check if your gateway supports currency anchoring. Even if your shop currency is USD, displaying prices in local currency with checkout increases trust.

4. Compare security and compliance features

Payment breaches destroy trust and can cost you millions. Your gateway must offer first-class security.

Security points to verify

PCI DSS compliance (non-negotiable for trustworthy gateways)
End-to-end encryption (serious gateways use TLS 1.2+ and tokenisation)
Fraud detection and chargeback prevention tools (Stripe Radar, Signifyd, etc.)
3D Secure 2.0 authentication (reduces chargeback liability)
Transparent data protection policies (how your data and customers' data are handled)

Balancing security and conversion

Too-strict security can create friction. For example, requiring 3DS verification for every transaction increases security but can frustrate customers used to one-click payment. The best gateways let you activate security conditionally based on risk profile.

5. Best gateways by use case

Different businesses have different needs. Here's how leading gateways compare by merchant type.

Startups & small merchants

Prioritise setup speed, low upfront costs and ease of use. Shopify Payments and Stripe are great for starting quickly, with no monthly fees and seamless integrations.

Subscription-based businesses

Subscriptions require reliable recurring billing, free trials, payment dunning and subscriber management tools. Stripe and Braintree (by PayPal) offer strong subscription support. Adyen works for enterprise-level subscriptions.

Enterprise & high volume

Enterprise-level merchants need custom pricing, multi-currency support, advanced compliance and direct bank connections. Adyen is the enterprise-level option; Stripe offers Stripe Connect for marketplaces; CyberSource (Visa) serves large businesses.

High-risk merchants

High-risk products or business models (subscriptions, supplements, CBD, etc.) have more difficulty being accepted. You'll need a specialised gateway that works with high-risk processors. CartDNA supports many high-risk gateways.

How to choose your Shopify payment gateway

1

Identify your markets & customer needs

Are you selling locally or globally? What payment methods do your customers expect? If you're in Europe, prioritise SEPA, Klarna, iDEAL support. If you're global, ensure the gateway supports local wallets.

2

Compare fees vs volume

Estimate your monthly transaction volume. Calculate how much you'd pay with each gateway. Don't forget hidden fees (dispute, cross-border settlement).

3

Test integration and UX

Checkout testing (sandbox mode) is crucial. See how smooth the experience is for buyers. Check if it integrates into your Shopify stack without complex coding.

4

Verify security and fraud tools

Read security documentation. If you sell high volume or high-risk categories, fraud prevention tools are essential.

5

Evaluate support

Payment issues must be resolved quickly. Check support SLAs, availability hours and API access.
