Payment methods for online stores: what retailers should compare

A long row of payment logos says little about whether checkout works well. Customers need their preferred method to be available and to work on their device. Retailers then need to match the payment reliably to the correct order.

Which payment methods suit your customers?

Start with the markets you actually serve. Cards and wallets can be convenient for mobile orders. Payment by invoice may be an important expectation for some customer groups, but comes with its own allocation of risk. Payment in advance can suit certain orders, provided you clearly explain when stock is reserved and dispatched.

For Switzerland, consider local methods such as TWINT. Check whether a provider supports the method for your business, currency and sales channel. Do not assume that a German store’s payment mix will suit other countries.

What belongs in the cost comparison?

• Transactions: fixed and percentage fees, including any minimum charges.
• Additional costs: currency conversion, refunds or chargebacks.
• Cash flow: payout schedules and possible reserves.
• Risk: responsibility for defaults, fraud and disputes.
• Processing: reconciliation of payments, fees and partial refunds.
• Store integration: setup, maintenance and compatibility with other extensions.

Calculate costs using your average order value and realistic order volumes. A fixed fee can matter more with many small orders than with a few large ones. Also consider the time your team spends resolving unclear transactions or processing manual refunds.

How should you test checkout before launch?

Test every payment method on mobile and desktop. Include a successful payment, a rejection, cancellation and returning from an external payment window. Then check the order and payment statuses in the store and inventory system. Delayed payment confirmations must also be handled correctly.

Test partial returns too. If only one item is returned, the refund and remaining balance must reconcile. Decide which system initiates refunds to prevent an accidental duplicate.

What differs between e-commerce platforms?

For Shopify, available payment options depend partly on the country and provider. The Shopify documentation is a useful starting point. PrestaShop and Shopware often use a payment provider’s extension. In every case, assess the actual integration with your order and accounting processes.

How do you know whether the selection has improved?

Track payment abandonment, technical errors, customer questions and accounting workload separately. A declined payment has a different cause from an unclear button. Compare similar periods and customer groups. A change in the payment mix alone does not demonstrate a business improvement.
