happybrush now plans purchasing and inventory with numi. The Munich-based sustainable oral care brand sells electric toothbrushes and the matching consumables through its own shop and through retail partners — combining two demand patterns in one business that could hardly be less alike.
Two very different demand patterns in one business
Hardware and consumables behave nothing alike. A toothbrush is a considered purchase concentrated around gifting seasons and promotions, sourced with long lead times that force commitments months ahead of the demand they serve. Brush heads and refills are the opposite: steady, repeat, and driven by an installed base that grows with every device sold.
Planning them with the same logic under-serves both. Add a retail channel that orders in large, lumpy quantities on its own promotional calendar, alongside continuous D2C demand, and the forecast has to distinguish between structurally different signals rather than smoothing them together. Across the full assortment and every sales channel, that distinction is where availability is won or lost.
With numi, happybrush combines these capabilities in one supply chain intelligence platform. Forecasts and replenishment proposals run directly on current data from weclapp, happybrush's ERP system.
The go-live includes:
- AI demand forecasting at SKU level to make demand planning more precise across hardware, consumables and bundles.
- Automated replenishment proposals and order creation to reduce manual effort and speed up purchasing workflows.
- Supplier performance monitoring with a full KPI system to create a shared, fact-based view of supplier reliability and lead times.
- Dynamic alerts for real-time market responsiveness so teams can react faster to changing conditions.
What changes in day-to-day purchasing
The result is less manual work, fewer stockouts and smarter purchasing decisions. By turning operational data into timely recommendations, happybrush's team can focus more of its expertise on the decisions that matter most to customers and the business.
We would like to thank the entire happybrush team for their trust and partnership. We are proud to support this next step in happybrush's supply chain transformation and look forward to the journey ahead.
