Case Study: Willemse boosts conversion by 10% with Mollie

How Willemse enhanced its conversion rate by 10% while expanding across Europe and maintaining resilience against fraud

Willemse, a French gardening ecommerce company expanding across Europe, needed to modernize its checkout experience after migrating to Shopify and integrating multiple markets and payment preferences. To support this growth and reduce friction at checkout, Willemse partnered with Mollie for Payments and Acceptance & Risk, including support for local payment methods and fraud prevention.

With Mollie, Willemse implemented a fast, simple integration that automatically adapted payment methods by country and used Dynamic 3DS to streamline authentication while staying PSD2-compliant. The result was a 10% increase in conversion rates and a 5% decrease in failed transactions, while also improving resilience against fraud and earning strong praise for Mollie’s responsive support.
