What a WMS does
A WMS turns orders into instructions and instructions into records. Its core processes are:
- Goods-in: off-loading, receiving, quality checks, capturing batch, expiry and serial numbers, and putaway to a chosen bin.
- Inventory: replenishment, cycle counting, slotting and reconciliation with the ERP.
- Goods-out: reserving stock, building waves, picking, consolidation, packing and loading.
Every step is confirmed, usually by barcode scan, so the system always knows what is where.
Who uses it
Operators see tasks on handhelds. Supervisors plan waves and watch progress. Inventory controllers run counts. The ERP receives confirmations automatically.
Where a classic WMS stops
A traditional WMS assumes the work is done by people. It tells an operator “go to bin A-12-03, pick 6”. It does not tell a shuttle which aisle to drive to, or a conveyor which branch to take. That is the job of a warehouse control system.
When a site adds automation, a standalone WMS needs a second system underneath it, and an interface between the two. See WMS vs WCS vs WES for how the layers divide the work, and how Kulmen covers them in one platform.
Signs you need one
- Stock is found by memory rather than by system.
- Picking errors are caught by customers, not by scans.
- Counting means closing the warehouse.
- The ERP and the shelf disagree.
Kulmen’s inbound, inventory and outbound capabilities cover these processes for operator-led warehouses and beyond.
