Custom subscriptions. SAP integration. PWA for fresh baby food.

Background

Nübee manufactures fresh, organic baby food for children aged 0–3 in Switzerland. The brand's proposition — fresh, nutritionist-designed meals delivered directly to families — comes with unusual logistics requirements: products need to be prepared to order, delivery windows must be scheduled, and the supply chain requires tight coordination between the platform, the kitchen, and third-party logistics partners. It is a fundamentally different eCommerce model from standard grocery or baby product retail.

The company had grown on a custom-built platform that had served the early MVP well but had become an engineering constraint. Adding new features, expanding to new markets, or improving the customer experience required disproportionate development effort. Nübee needed a modern, maintainable platform that could scale with their ambitions.

The Challenge

The technical requirements were more complex than a typical retail migration:

• The subscription feature was central to Nübee's business model — parents subscribe to weekly or bi-weekly boxes — but off-the-shelf Shopware subscription plugins could not meet the specific requirements
• The platform needed to integrate with SAP for fulfilment and Mailchimp for CRM and lifecycle marketing
• Safari browser support issues on the previous platform needed to be resolved
• The delivery scheduling system needed to notify the kitchen partner at a defined daily cut-off time
• The architecture needed to support a Swiss MVP with clean expansion paths to Germany and Austria

Our Solution

After a full discovery phase including UX research, Google Analytics data analysis, and user interviews, Divante recommended Shopware 6 as the backend with Shopware PWA as the frontend — chosen over the standard Shopware storefront for its performance advantages and frontend flexibility.

The subscription functionality was built from scratch rather than adapted from an existing plugin, giving Nübee complete control over the subscription logic, renewal rules, and customer management. The delivery scheduling system was engineered to collect daily orders and trigger notification to Nübee's kitchen partner at 4 a.m. each morning — matching the production preparation schedule. SAP and Mailchimp integrations were implemented alongside custom analytics event tracking and full SEO implementation.

The multi-country architecture used a single Shopware 6 backend with country-specific PWA front ends differing by currency, catalogue, payment method, and delivery options.

Impact & Results

• The Swiss MVP launched successfully, establishing the foundation for multi-country expansion
• The platform architecture cleanly separates country-specific behaviour from the core system — enabling Germany and Austria rollouts without backend duplication
• The subscription engine, built entirely to Nübee's specification, gives the business full control over its recurring revenue model — the capability that the previous custom platform had been unable to provide
