About the client

The client is a Norwegian e-commerce retailer managing more than 10,000 SKUs тwith frequent promotions and seasonal demand spikes. As a pure online retailer, the company’s customer experience depends heavily on accurateproductavailability and reliable delivery promises. However, the business operated across multiple disconnected systems including the storefront, OMS, warehouse platforms, and third-party logistics providers. During peak periods such as Black Friday, these systems often became desynchronized, causing operational disruptions and customer dissatisfaction.

Establishing Control Over Inventory and Delivery Execution

The custom solution we implemented aligned promotions with real-time inventory and delivery capacity, ensuring that only fulfillable products are offered for sale.

  • Promotions not aligned with actual inventory
  • Inconsistent inventory across systems
  • Selling products not available in stock
  • Unreliable delivery commitments to customers
  • Peak demand causing fulfillment disruptions
  • High volume of delivery-related customer issues
  • Siloed decisions across marketing and operations

Technology solution

  • Unified data layer across core operational systems
  • Near-real-time synchronization of inventory data
  • Integration of storefront, OMS, and WMS
  • Validation rules for inventory before promotions
  • Delivery capacity linked to product availability

Technologies we use to move your projects forward

The collaboration began with a detailed diagnostics of the client’s operational flows across promotions, inventory management, and delivery execution. Particular attention was given to how data moved between systems and where discrepancies led to overselling, stock-outs, and unreliable delivery commitments. Based on these insights, a unified operational approach was defined to align sales activity with real inventory availability and delivery capacity, ensuring consistent and controllable fulfillment across all channels.
