- Project Results
-
We developed a "client-centric" WMS that radically simplifies operator work, reducing the process to just 5 actions per order. Operators follow the entire path guided by LED indicators and master the system in just 1 day, while strict process controls ensure order fulfillment accuracy above 99% compared to 97-99% for the best solutions on the market. This enables order fulfillment within 1 day at a cost 40% lower than the market average (adjusted for region).
The uniqueness of the project

- Difficulty of implementation
-
To ensure 1-day delivery, all stages must fit within 24 hours — picking, sorting, packing, airport delivery, loading, air transportation (when necessary), unloading, and last-mile delivery.
Warehouse operations have less than 1 hour for completion.
High availability: Both customer-facing and internal system components must operate 24/7 without downtime, even during updates.
High load and throughput: Users browse more than 1,000 products per visit, requiring delivery of several billion photos per day.
Unreliable networks: To protect against failures, multiple backup channels are implemented in all components.
Tight deadlines: Only 6 months to release MVP and 12 months to achieve target metrics.
No existing codebase: For clean intellectual property rights, legacy code had to be discarded, requiring development in new languages with a new development team. - Project Description
-
The customer app, supplier management, inventory tracking, logistics, and point of sale are unified into a single system complex — separate but closely integrated. The most unique component is the warehouse management system (WMS).
Existing WMS solutions are typically created with an industrial approach — to support a wide range of manufacturing or logistics processes and provide flexibility for users. This approach is impractical for a marketplace dealing with everyday consumer goods. Our tests showed that standard WMS systems require 20–30 user actions to process a single order.
- Project geography
-
The project was developed jointly by staff in Russia and Kazakhstan, following the KazanExpress model. Implemented in Kazakhstan. Potential markets include Turkey and Azerbaijan.
The logistics chain begins in China.
