Modernising for Growth

To support continued growth and innovation, Bulk needed to modernise its digital commerce platform. Objectives included improving performance during peak periods, enhancing user experience across devices, and delivering flexible delivery and return options. Above all, the site had to reflect Bulk’s brand ethos—best-in-class experience for every customer.

APPROACH

Insight Led, Performance Driven

Through workshops with Bulk and Adobe, we developed a strategy rooted in customer insights and market analysis. We improved mobile usability, upgraded the PDP gallery, implemented Akeneo for better product management, and integrated Hubbox for flexible deliveries and returns. Performance enhancements ensured the site could handle over 19,000 concurrent users, while CRO and UX refinements were rolled out iteratively, based on real user behaviour and feedback.

The Solution

A Seamless, Scalable Solution

In partnership with The Pixel, Bulk implemented a high-performance site on Adobe Commerce, integrating technologies like Akeneo PIM and Hubbox to optimise content, product discovery, and delivery.

UX improvements—especially around the product gallery and checkout—made shopping smoother and more intuitive.

The platform was also fine-tuned to handle peak traffic, enabling record-breaking Black Friday sales without queueing or downtime.

Features like Bulk Boost, offering unlimited free delivery, and enhanced PDP zoom functionality helped elevate the overall experience.
