Shopify POS solution replacing Cegid Y2 to unify the omnichannel repository with Dynamics 365
Context
The Manufactures de Mode (MDM) group wanted to modernize the retail ecosystem of three of its Houses (Maison Michel, Goossens, Causse), spread across fewer than 10 boutiques in France, the United Kingdom, and Spain. The major challenge was to gradually replace the existing Cegid Y2 tool with the omnichannel POS solution with Shopify in order to unify the retail and e-commerce experience.
The main objective was to centralize operations around a single repository (products, inventory, customers) to streamline omnichannel capabilities, while securing the rollout and preserving the operational best practices of the in-store teams.

intervention
Numendo deployed a comprehensive support approach structured around 5 key phases, managed under rigorous cross-functional governance:
• Data Migration: Analysis of Cegid exports and execution of full mapping to Shopify POS for the product catalog (SKUs, variants), inventory by location, and customer files.
• Tailored Configuration per House: Configuration of the multi-store, multi-location, and multi-currency setup, detailed definition of roles/permissions (Staff, Boutique Manager, Retail Manager), selection of POS hardware (iPads, printers), and payment integration via Shopify Payments.
• Interfaces & Workflows: Alignment of native workflows with Shopify E-commerce and integration with the existing ERP (Dynamics 365), while anticipating complex specific use cases (department stores like Harrods, hotel checkout processing in Marbella).
• In-Store Rollout: Implementation of a secure methodology starting with a pilot boutique (Maison Michel) for field validation, followed by a gradual rollout in close coordination with IT, Retail, and Operations teams.
• Training & Onboarding Support: Creation of user documentation and hosting of targeted hands-on workshops (inventory management, stocktakes, returns), complemented by post-go-live hypercare support to ensure a seamless transition.

results
The deployment was executed in a controlled and secure manner throughout 2026. The three Houses now benefit from a modern, unified retail platform that eliminates data silos thanks to a single master repository. All specific processes have been documented, settings validated under real-world conditions, and in-store teams are now fully autonomous and operational on their new point-of-sale tool.
