Shopper-first grocery transformation in Europe

Shopper-first grocery transformation in Europe starts with a simple truth: shoppers have changed faster than many retail operating models. Established grocers across the region are navigating a more complex reality than the one that shaped their legacy success. Traditional hypermarket traffic is under pressure. Demand for healthier and more locally sourced food has moved into the mainstream. Online grocery is growing in a highly competitive environment shaped by local specialists, large incumbents and global digital players. At the same time, retailers cannot afford to abandon the brand heritage, store networks and customer trust that made them market leaders in the first place.

This is why grocery transformation in Europe cannot be reduced to a replatforming program or a better website. It has to be shopper-first, omnichannel and operationally grounded. It has to connect ecommerce to stores, fulfillment, merchandising and marketing. And it has to build the organizational capability to keep improving long after launch.

Carrefour offers a powerful example of what that looks like in practice. Facing declining visits to traditional hypermarkets, rising demand for healthy and locally sourced food and intensifying digital competition, the retailer recognized that its digital future depended on more than adding new features. Carrefour had strong brand equity, loyal customers and a broad mix of store formats, but its online assets were fragmented and organizational silos made change difficult to scale. Publicis Sapient helped Carrefour create a cohesive digital vision, unify more than 350 disconnected digital projects into agile squads and launch the first version of a new ecommerce platform in six months. Since launch, Carrefour has reported a 1.5x increase in conversion, while also accelerating its release cadence so teams could deliver major releases weekly without downtime and continuously enhance the customer experience.

The lesson is not simply that speed matters. It is that speed at scale comes from alignment. European grocery leaders often do not struggle because they lack ambition. They struggle because years of growth, acquisitions, banner complexity and channel expansion have produced fragmented platforms, duplicated capabilities and delivery models built for control rather than adaptation. The result is familiar: teams work hard, yet change remains slow; customer experience ambitions are high, yet journeys feel disconnected; ecommerce grows, yet the business still operates in channel silos.

A shopper-first transformation addresses those structural issues directly.

First, it starts with a unified digital vision anchored in shopper needs rather than internal structures. In grocery, shoppers do not distinguish between ecommerce, store operations, loyalty, fulfillment and service. They simply expect the experience to work. That means retailers need a common foundation that supports discovery, ordering, pickup, delivery, promotions and personalization across touchpoints. Carrefour’s transformation was designed to support not only ecommerce growth, but also a broader food transition strategy and future capabilities such as mobile, voice and personalization at scale.

Second, it connects digital commerce with physical retail formats instead of treating online as a separate business. This is especially important in Europe, where store networks, local assortment differences and established shopping habits remain strategic assets. Across Publicis Sapient’s grocery and retail work, the goal is consistently to integrate digital channels with existing in-store operations. In practice, that can mean linking desktop and mobile shopping journeys with store fulfillment, pickup experiences, merchandising, inventory visibility and localized customer engagement. Long-term grocery transformation programs have shown that when digital services are connected to physical operations, retailers can improve supply chain performance, increase picking efficiency, expand delivery capacity and create smoother omnichannel experiences.

Third, it modernizes the technology estate in a way that supports continuous change. Many heritage grocers are held back by monolithic commerce stacks, rigid release processes and disconnected content or data environments. Publicis Sapient helps retailers move toward more flexible architectures built around APIs, services, cloud-based platforms and modular capabilities. Across multiple retail transformations, this has enabled faster deployment, more resilient performance, easier integration and the freedom to evolve without disrupting the business. The objective is not modernization for its own sake. It is to create the technical foundation for faster learning, more reliable execution and better shopper outcomes.

Fourth, it changes how work gets done. One of the clearest lessons from Carrefour and other large retail transformations is that the operating model matters as much as the platform. Publicis Sapient helps organizations replace fragmented project structures with integrated, cross-functional teams that combine strategy, product, experience, engineering and data expertise. This model breaks down silos, improves accountability and allows teams to measure, iterate and respond quickly to customer behavior. What emerges is not a one-time transformation team, but a new organizational capability for ongoing delivery.

That capability is increasingly what separates short-term progress from long-term relevance. Retailers such as Loblaw focused on building a world-class digital organization around self-sufficiency, trust and scalability, with a continuous improvement mindset across the business. A top global grocer’s decade-long transformation journey shows how sustained change can evolve from online grocery scaling into supply chain optimization, agile engineering, API-based architecture, improved picking and delivery performance, and continued innovation across store and digital experiences. These examples reinforce a critical point for European leaders: transformation is not a campaign. It is a muscle.

For established European grocers, that creates a practical playbook:
Publicis Sapient helps retailers do exactly that. We do not approach grocery transformation as a standalone technology implementation. We partner with retailers to reshape both the digital business and the operating model behind it. That includes strategy and consulting, customer experience and design, technology and engineering, data and AI, and product management. Our role is to help heritage retailers modernize without losing what makes them distinctive: their local relevance, their trusted brands, their physical presence and their relationship with shoppers.

In Europe, that balance matters. The winners will not be the retailers that chase digital novelty for its own sake. They will be the ones that turn legacy strength into a modern advantage: using data more intelligently, connecting physical and digital journeys more seamlessly, and building organizations that can keep evolving as shopper expectations continue to change.

Shopper-first grocery transformation is ultimately about making established retailers more relevant, more resilient and more responsive. Carrefour demonstrates what is possible. The broader opportunity for European grocers is to take those lessons and build a transformation model designed for their own complexity, their own markets and their own future.
