Paytrail or Kustom? How to choose a payment solution for your online store

- Paytrail brings Finnish payment methods, such as online banking, cards and mobile payments, into the online store checkout.
- Kustom, formerly Klarna Checkout, is a complete checkout with payment methods, prefilled details and delivery options.
- For a domestic store Paytrail is often enough. If you sell to several countries or want to optimise the whole checkout, include Kustom in the comparison.
Choosing a payment solution is in practice a choice between two models: a payment service provider inside your own checkout, or a complete ready-made checkout. Paytrail and Kustom represent these two models. In this article we compare them from the point of view of a WooCommerce online store.
Paytrail and Kustom side by side
Paytrail: Finnish payment methods in your own checkout
Paytrail is a Finnish payment service provider that brings online banking, cards and mobile payments together under one agreement. The customer fills in their details in the WooCommerce checkout and chooses a payment method, after which the payment is made through Paytrail. Invoice and instalment options come through partners. Getting started is quick, and the look and fields of the checkout page stay fully under your control.
Kustom: a complete checkout
Kustom is the former Klarna Checkout, which became an independent company. It replaces the checkout page of the online store with its own checkout, where payment methods such as cards, Klarna, Apple Pay and PayPal, as well as delivery options, are in the same view. Details of returning customers are prefilled, which speeds up buying. Kustom supports selling to several countries with local payment methods.
