WMS
Warehouse Management System
A system for managing warehouse operations — goods receipt, put-away, picking, dispatch, stock counts and movement tracking at location and batch level.
What is WMS?
WMS (Warehouse Management System) is specialised software for the operational management of warehouse activities — receiving goods, putting them away in the optimal location, picking according to an order pick list, packing, dispatch, and reverse movements. A WMS goes into a level of depth that a classic ERP warehouse module does not reach: it tracks movements at the level of rack positions, batches, expiry dates, and specific pallets.
A modern WMS typically operates via mobile terminals or barcode scanners that guide the warehouse worker to the exact position and confirm every operation with a EAN or SKU scan. This minimises errors — a well-deployed WMS reduces dispatch error rates below 0.5%.
Key WMS functions:
- Location management — ABC analysis, fast-moving vs. slow-moving stock
- Cross-docking — goods arrive and leave without being put away into storage
- Wave picking — picking multiple orders simultaneously
- FIFO / FEFO (first-in-first-out / first-expired-first-out for food and pharma)
- Reverse logistics — processing returns
When it is used
WMS is deployed in larger warehouses (typically from 1,000 m²), distribution centres, e-commerce logistics, and 3PL operators. For small warehouses an ERP warehouse module is sufficient.
See the Warehouse module, the e-commerce industry page, and the logistics industry page.

In Modulario
The Warehouse module in Modulario includes WMS functionality — it supports mobile terminals, locations, batches, and expiry dates. For very large warehouses it can be integrated with a specialised WMS via API.
For critical operations (dispatch, stock count), Modulario supports dual-scan — the warehouse worker first scans the location, then the product, eliminating mix-ups. The mobile terminal interface is optimised for gloved hands (large buttons), noisy environments (vibration feedback), and unstable WiFi (offline mode with local cache).
