Case Study

ENGIE eCommerce 2025

ABSTRACT
ENGIE eCommerce 2025 introduces a headless platform with unified APIs and a centralized product catalog based on Conga CPQ, drastically reducing shopping carts.

Where: italy
Challenge
ENGIE needed to modernize an eCommerce platform that was no longer suitable for supporting new channels, high performance, and unified sales processes. The client had to manage a complex product catalog across multiple fronts and reduce the drop rate along the funnel. The challenge required a more modern architectural model, centralized access to the Conga CPQ catalog, and a smooth process for both new and existing customers.
Approach
We adopted a headless architectural approach, defining an API-first backend that unifies processes and simplifies channel integration. In collaboration with ENGIE and the front-end partner, we designed optimized flows, standardized the use of the Conga CPQ catalog, and improved performance. The iterative approach ensured strong governance, consistency, and faster time to market.
Solution
The solution features an API-driven backend that manages the entire funnel (login, blacklist checks, document upload, step-by-step cart, submission, and signing). The Product Catalog was centralized through Conga CPQ: a summary batch consolidates more than 10 objects into a single simplified model, speeding up data access and enabling consistent integration across channels. The headless architecture allows rapid front-end evolution and enables new digital partners through standardized logic.
