Transforming Siman’s omnichannel strategy with Janis Commerce’s Distributed Order Management

Siman, Central America’s leading department store, was facing critical operational challenges that limited its omnichannel capabilities. By implementing Janis Commerce’s Distributed Order Management (DOM), the company was able to automate key processes, reduce manual workload, and significantly improve both logistical efficiency and customer experience.

Results obtained

50% reduction in order rejection rate

Optimized stock flow

Increased accuracy in order picking and packing

Main challenge

Siman was dealing with inefficient and unreliable stock management, along with a logistics operation plagued by delays and a highly manual fulfillment process. On top of that, their omnichannel order allocation was limited and difficult to scale—creating a major roadblock for the sustainable growth of their digital channel.

Janis Commerce's solution

‍

We implemented a comprehensive solution that combined our OMS, TMS, and WMS modules with three key applications: Warehouse, Order, and Delivery.

At the heart of the project was the adoption of our Distributed Order Management (DOM) — the first and only one developed in Latin America. This system enabled Siman to automatically select the most efficient warehouse for each order, optimizing both fulfillment and delivery while significantly improving their omnichannel order management capabilities.

Thanks to our DOM’s flexibility, which quickly and intelligently assigns orders across multiple warehouses, Siman was able to drastically reduce manual workload and deliver a smoother, more reliable customer experience.
