About WCFab

WCFab came to Web Shop Manager with a clear mission: elevate their eCommerce experience and deliver high-performance diesel parts directly to consumers. Known for their engineering excellence and custom fabrication, WCFab needed a site that matched their brand’s reputation—complete with a streamlined B2B dealer portal and a full redesign to support growth and conversion in their diesel truck parts eCommerce channel.

WCFab Success Story

Despite WCFab’s strong brand and loyal customer base, their legacy site introduced friction at critical points in the purchase journey. The cart was embedded in a cluttered layout with competing links and unclear payment options. Checkout fields were dense and poorly optimized for mobile, leading to drop-offs and abandoned carts. Customers struggled to complete purchases efficiently, especially on smaller screens.

  • WCFab aimed to strengthen their direct-to-consumer diesel truck parts eCommerce channel and increase conversion rates across mobile and desktop.
