A Shopify Plus store owner seeks to add payment method surcharges through their Mollie gateway integration (e.g., +1% for credit cards, +2.5% for Klarna, +1% for PayPal).
Suggested approach:
Critical compliance warning:
Before implementation, verify local consumer protection laws. Many regions—particularly the EU—restrict or prohibit surcharges on specific payment methods like Visa/MasterCard. Non-compliance risks legal consequences and potential account issues.
The discussion remains open with no confirmed solution implemented yet.
Hi All,
We have integrated the Mollie payment gateway in our Shopify Plus Store. Now we need to enable surcharges for each payment method selected by the user, for example:-
Credit card → +1% surcharge
Pay with Klarna → +2.5% surcharge
Paypal → + 1% surcharge
How can I implement this?
What are the approaches available?
Can someone please help on this

One approach is to work with certified Shopify payment app development partners like CartDNA. You can ask them to build a custom payment application that includes surcharge functionality tailored to your specific needs. These types of custom apps can be designed to simulate surcharges by adding fee-based line items, using checkout UI extensions, or implementing Shopify Functions (not limited to Shopify Plus , these custom app can be work with any Shopify Subscriptions ).
However, make sure to check your local consumer protection laws first. In many regions-especially in the EU-adding surcharges for specific payment methods (like Visa or MasterCard) is restricted or outright prohibited. Implementing surcharges without compliance could lead to legal or account issues.
Happy and Safe Selling
