Choosing the Perfect Payment Gateway for Your Shopify Store β€” illustrated guide by CartDNA

A practical framework for Shopify merchants to select the right payment gateway for their business model and target markets.

Why Your Payment Gateway Is a Growth Decision β€” Not Just a Technical One

Most Shopify merchants pick a payment gateway once and never revisit it. That's a costly mistake. As you scale into new markets, launch new product lines, or target customers who prefer bank transfers over credit cards, the 'good enough' gateway you started with quietly drains conversions and adds unnecessary fees.

The payment gateway you choose determines which countries you can sell to, which currencies you can accept, which local payment methods are available at checkout, and how much you pay per transaction. Get it wrong, and you're losing revenue at the most valuable part of your funnel β€” the moment a customer decides to pay.

What Your Gateway Actually Controls

  • Checkout conversion rate β€” especially for local payment method availability
  • Transaction fees β€” from 0% with Shopify Payments to 2%+ with some third-party gateways
  • Supported countries and currencies for selling internationally
  • Fraud protection, chargeback management, and dispute resolution

The Three Types of Payment Gateways β€” and When to Use Each

Not all gateways are equal. Understanding these three categories will help you choose the right one β€” or the right combination β€” for your business.

Shopify Payments β€” Simplest Setup, Native Integration

Shopify Payments is Shopify's own gateway, powered by Stripe. It removes the additional transaction fee Shopify charges when you use a third-party gateway, making it the most cost-effective option for eligible merchants.

Best for

  • β€’ Merchants in supported countries (US, UK, EU, AU, CA and more)
  • β€’ Stores wanting a single, seamless checkout experience
  • β€’ Businesses that want to avoid Shopify's third-party gateway fees (0.5–2%)

Limitations

  • β€’ Not available in all countries β€” restricts many international merchants
  • β€’ Account freezes can happen without warning if Shopify flags your business
  • β€’ Limited flexibility for high-risk or niche product categories

Third-Party Gateways (Stripe, PayPal) β€” Flexibility and Global Reach

Stripe and PayPal are the most widely used third-party gateways for Shopify. They're available in more countries than Shopify Payments and offer powerful APIs for customisation β€” but they come with Shopify's additional transaction fee on top of their own processing fees.

Best for

  • β€’ Merchants outside Shopify Payments' supported countries
  • β€’ Stores with advanced checkout customisation requirements
  • β€’ Businesses that need multi-currency or recurring payment support

Watch out for

  • β€’ Shopify adds 0.5–2% per transaction on top of gateway fees
  • β€’ PayPal checkout friction can reduce conversion for some audiences
  • β€’ Stripe requires developer knowledge for advanced customisation

Local PSPs (Mollie, Adyen, etc.) β€” Best Conversion in Specific Regions

Local Payment Service Providers specialise in regional payment methods that global gateways don't cover well. If you're selling into the Netherlands, Germany, Poland, or Belgium, adding a local PSP alongside your primary gateway can significantly increase checkout completion.

Best for

  • β€’ Stores targeting European, Asian or LatAm customers
  • β€’ Markets where local payment methods dominate (iDEAL, SEPA, BLIK, Bancontact)
  • β€’ Merchants with high cart abandonment from international traffic

Considerations

  • β€’ Additional integration and setup complexity
  • β€’ Separate reporting and reconciliation per provider

CartDNA specialises in connecting Shopify stores to local PSPs β€” without requiring a local business entity or bank account in each market.

CartDNA Insight: For most growing Shopify stores, the smartest strategy is Shopify Payments as the primary gateway, with a local PSP added per market as you scale into Europe, LatAm or Asia. This minimises fees while maximising local checkout conversion.

What to Look for Beyond the Fee β€” 8 Factors That Actually Matter

Fee comparisons are the start β€” not the end β€” of choosing a gateway. These eight factors have a direct impact on your conversion rate, your customer experience, and your operational costs.

  • Supported payment methods β€” Can customers pay with their preferred method (iDEAL, Klarna, SEPA, Bancontact, BLIK) in your target markets?
  • Checkout experience β€” A clunky redirect to a third-party payment page increases abandonment. Native or embedded checkouts convert better.
  • Fraud protection and chargeback management β€” Advanced fraud tools reduce disputes and protect revenue, especially for high-ticket or digital products.
  • Payout speed and currency settlement β€” Does the gateway pay you in your local currency? How quickly? Slow payouts create cash flow problems.
  • Recurring billing support β€” If you run subscriptions or instalment payments, your gateway must support this natively.
  • Multi-currency pricing β€” Can customers see prices in their local currency, or do they get hit with conversion surprises at checkout?
  • Reporting and reconciliation β€” A gateway with strong dashboards saves hours per month on accounting and fraud monitoring.
  • Scalability β€” Can the gateway handle peak traffic during campaigns or seasonal surges without downtime?

The wrong gateway doesn't just cost you transaction fees β€” it costs you customers at the most critical moment in their journey.

How to Build a Scalable Shopify Payment Stack

Rather than searching for a single 'perfect' gateway, think in layers. The best Shopify merchants use a tiered payment strategy that starts simple and scales as they grow.

Layer 1 β€” Start with Shopify Payments or Stripe for your primary market
Layer 2 β€” Add PayPal as a trust signal for customers who prefer wallet payments
Layer 3 β€” Integrate local PSPs (iDEAL, Klarna, SEPA) as you expand into Europe
Layer 4 β€” Add Buy Now Pay Later (BNPL) options like Klarna or Afterpay to increase average order value
Layer 5 β€” Add a backup gateway for redundancy β€” if your primary gateway goes down, sales don't stop
Review quarterly β€” Gateway fees and feature sets change; reassess your stack every 3–6 months

The Recommended Payment Stack for Growing Shopify Stores

Core Stack (Most Merchants)

  • Redundancy so a single gateway outage never kills your revenue

Frequently Asked Questions

Should I use Shopify Payments or Stripe for my Shopify store?

If Shopify Payments is available in your country, use it first β€” it removes Shopify's additional transaction fee (0.5–2%) and integrates natively with your checkout. Stripe is the better choice if you're outside Shopify Payments' supported countries, need advanced API customisation, or operate in a category that Shopify Payments restricts.

What is the additional transaction fee and how do I avoid it?

Shopify charges an additional transaction fee (0.5–2% depending on your plan) every time you use a third-party payment gateway. The only way to avoid it is to use Shopify Payments as your primary gateway. If Shopify Payments isn't available in your country, this fee is unavoidable β€” but can be partially offset by negotiating better processing rates with your chosen gateway.

What payment methods should I add for European customers?

European payment preferences vary significantly by country. For the Netherlands: iDEAL is used in over 70% of online transactions. For Germany: SEPA bank transfer and Klarna are dominant. For Belgium: Bancontact. For Poland: BLIK. For France and Southern Europe: cards and PayPal. Adding these through a local PSP integration like CartDNA can reduce European cart abandonment significantly.

Can I use multiple payment gateways on one Shopify store?

Yes. Shopify allows you to have one primary gateway (such as Shopify Payments or Stripe) plus additional payment methods (such as PayPal, local PSPs, and BNPL providers like Klarna). CartDNA specialises in adding local payment methods to Shopify stores as supplementary checkout options alongside your primary gateway β€” without disrupting your existing setup.
