Choosing between Mollie and Unzer as a PSP can be a challenge for many businesses. That's why we make a comparison in various categories to provide merchants with an informed basis for their decision.

Integration and ease of use

Mollie is characterized by its user-friendly platform, specifically designed for easy integration with existing systems. Mollie's API is well documented and offers developers the flexibility to implement customized solutions. In addition, numerous plug-ins for popular e-commerce platforms such as Shopware, WooCommerce and Magento are available to facilitate integration.

Unzer also offers a range of integrations, but some users report difficulties with implementation, especially with less well-known or customized systems. Unzer's integration with WooCommerce can be technically challenging, requiring additional effort and possibly external support.

Fee structure

A decisive factor when choosing a payment provider is the fee structure. Mollie is known for its transparent pricing, with no hidden costs. The transaction fees are clearly defined and vary depending on the payment method used. This allows merchants to keep costs under control at all times.

In contrast, Unzer is often criticized for its higher and more complex fees. Unzer's cost structure can be difficult to understand. This can make financial planning difficult, especially for small and medium-sized companies.

Customer service

Another important aspect is customer service. Mollie stands out for its fast and efficient customer service. Merchants on Trustpilot report short response times and competent staff who are able to resolve technical and operational issues promptly. This service is available in multiple languages and offers support through various channels, including email, phone and live chat.

Unzer is also rated positively on Trustpilot, but it is primarily end customers who rate it. If you look at the reviews from retailers, however, they sometimes criticize the long response times and the sometimes unhelpful customer service for retailers. This can be particularly problematic when urgent questions or technical problems need to be resolved quickly in order to maintain business operations.

International reach

For companies with an international focus, the global reach of a payment provider is crucial. Mollie offers a wide range of global and local payment methods and supports multiple currencies, making it ideal for businesses looking to grow in multiple countries.

Unzer has placed its focus more on global payments, which may be beneficial for some merchants, but could limit businesses that value local payment methods in different countries.

Flexibility and customization options

A key advantage of Mollie is the high flexibility and customizability of its payment platform. Merchants can easily add new payment methods and adapt their payment processing to changing business needs - simply by using a slider in the dashboard. The platform also provides detailed reports and analytics to help merchants better understand and optimize their payment flows.

Unzer also offers customization options, but these are often less extensive and may require more technical expertise. Unzer's flexibility is limited in some areas, which can be a challenge for businesses that need to respond quickly to market changes.

Security and reliability

Both providers place great emphasis on the security and reliability of their services. Mollie is PCI-DSS certified and offers advanced security features to protect both merchants and customers. Regular updates and improvements ensure that the platform complies with the latest security standards.

Unzer also offers comprehensive security measures and strives to ensure a secure payment environment. Nevertheless, some users have reported occasional technical issues that could affect the reliability of the platform.

Conclusion

While Unzer scores in some areas such as regional specialization, Mollie offers a more attractive package overall with clear advantages in terms of ease of use, fee structure and customer service. The greater flexibility and international reach make Mollie a preferred choice for businesses looking for a reliable and future-proof payment platform. If you are looking for an alternative to Unzer, Mollie could be the ideal solution for your business.
