Retrotec

Retrotec is a global leader in manufacturing precision air measurement equipment for building performance testing. Their products are used by engineers, energy auditors, and researchers around the world. With a strong presence in both North American and European markets, Retrotec needed a modern, secure e-commerce platform that could serve multiple regions seamlessly while maintaining platform stability and security.

What Was the Problem?

The Challenge

Retrotec’s website was running on an outdated version of Magento 2, which introduced several issues affecting both functionality and security:

Checkout Failure

The broken checkout flow disrupted purchases and hurt customer trust.

Minimal Disruption

The outdated Magento core left the site open to potential security threats.

Broken Multi-Storefront Configuration

Retrotec operated multiple regional storefronts, including one for the European Union. However, localization was not working correctly, resulting in:
  • Incorrect currency displays
  • Unsupported or mismatched payment gateways
  • Lack of region-specific content and product visibility
  • Confusing navigation for international users
With B2B and B2C customers relying on the platform, Retrotec needed a rapid and robust solution to restore functionality, improve user experience, and ensure compliance with regional e-commerce requirements.

How We Solved It

Our Approach & Solution

Nexus Box delivered a multi-phase solution focused on stability, localization, and conversion optimization.

Magento Core Upgrade

We began by upgrading Magento to the latest secure version, which offered:

  • Modern PHP compatibility
  • Security patches and performance enhancements
  • Long-term stability
  • Future extensibility

All custom modules and themes were audited and refactored where necessary to ensure compatibility with the new core.

Multi-Storefront Localization Fixes

We repaired and enhanced the multi-store architecture to ensure each storefront delivered the correct user experience. Specific improvements included:

  • GeoIP Detection: Integrated automatic geolocation-based redirection to send users to the appropriate regional storefront (e.g., US vs. EU).
  • Localized Content & Currency: Ensured that each storefront displayed correct product details, pricing, tax rules, and legal notices relevant to the user’s location.
  • Improved Admin Controls: Streamlined the backend management of regional store views for easier product and order management.

Payment Gateway Integration by Region

To ensure seamless and secure checkout across different regions, we implemented region-specific payment methods:

  • Authorize.net was configured for the North American storefront.
  • Mollie was integrated for the European storefront, supporting a wide range of EU payment methods like SEPA, iDEAL, and Bancontact.

These updates not only fixed the checkout flow but also improved payment success rates and regional trust signals.

Site Stability and Performance

In parallel with the functionality upgrades, we audited the site for bottlenecks and made optimizations to improve page load speed and backend responsiveness, creating a better experience for both customers and administrators.
