How to Add Swish to WooCommerce (Complete Guide for Sweden)

Introduction

Swish is one of the most widely used payment methods in Sweden, owned by the Swedish bank system, enabling instant mobile payments between consumers and merchants. However, WooCommerce does not support Swish natively, so you need a payment provider to enable it.

In this guide, you’ll learn how to add Swish to WooCommerce, compare different solutions, and understand why some merchants choose cost-efficient alternatives like Briqpay to avoid unnecessary transaction fees.

What is Swish?

Swish is a mobile payment system used in Sweden that allows instant transfers between bank accounts using a mobile phone number. It is trusted by millions of users and is a preferred payment method for Swedish consumers. Swish accounts for 20-30% share of checkout in Sweden, making it a must for most retailers.

Does WooCommerce support Swish?

No, WooCommerce does not support Swish out of the box. To enable Swish, you need a payment gateway or provider that connects WooCommerce to the Swish network.

Common options include:

• Stripe integrations (via third-party solutions)
• Klarna
• Dedicated Nordic payment providers (eg. mondido, nets, swedbank pay).

How to add Swish to WooCommerce

Step 1: Choose a payment solution

Choose a provider that supports Swish in Sweden and integrates with WooCommerce.

Step 2: Install WooCommerce plugin

Install and activate your payment gateway plugin.

Step 3: Configure Swish

• Enable Swish in the payment settings
• Set SEK as currency
• Connect API credentials

Step 4: Test checkout flow

Run test transactions to ensure Swish works correctly on both mobile and desktop flows.

Comparison of Swish payment solutions for WooCommerce

Different providers handle Swish differently, especially when it comes to pricing and transaction fees.

Most providers charge:

• Setup fees (sometimes)
• Monthly fees
• Per-transaction fees (%)

This can become expensive as volume grows.

Briqpay (cost-efficient alternative)

Briqpay offers a different approach designed for merchants who want more control over payment costs.

Key advantages:

• No percentage-based transaction fees from the platform layer (depending on agreement setup)
• Unified checkout across payment methods
• Optimized for localization
• Simplified Swish integration for WooCommerce merchants

This makes Briqpay particularly interesting for merchants with growing volume where per-transaction fees from traditional providers can become significant over time.
