What is a WMS?

WMS (engl. Warehouse Management System) is a software system for managing warehouse operations.. It acts as the digital brains of your warehouse, keeping everything organized.

At Pulmaton, we offer Valvomo WMS —a system designed to replace traditional Excel spreadsheets and pen-and-paper tracking by automating routine tasks and minimizing human error.

What does a WMS actually do?

A WMS guides warehouse staff step-by-step through every phase of daily operations. While traditional accounting or basic Enterprise Resource Planning (ERP) systems only know what items you have and how many, a WMS knows exactly where those items are located and how they should be handled. Here is how a WMS works in practice:

• When new stock arrives: The system instructs staff on which specific shelf and bin to store each product.
• When inventory levels change: Stock updates immediately across all channels, seamlessly syncing with your online store so customers can’t accidentally purchase out-of-stock items.
• When picking an order: The software shows the exact shelf location and uses barcode scanning to ensure the correct item is selected every time.
• When shipping a package: It automatically prints shipping labels and packing slips.

Our Valvomo WMS S keeps your inventory accurate and tracks every item movement in real time. If needed, it can be fully customized to match your warehouse’s unique operational requirements.

How does it differ from Excel?

Scenario	Excel Spreadsheet	WMS System
Inventory Levels	Someone forgets to update the sheet—stock figures become inaccurate.	Updates automatically across all systems in seconds.
Product Location	"The product is in the warehouse" (but on which shelf?).	"The product is on Shelf A, Level 3, Bin 5."
Errors	The wrong item gets shipped to a customer because two products looked identical.	A barcode scanner alerts the operator instantly if the wrong item is picked.

Who is a WMS designed for?

Adopting a WMS usually becomes essential when:

1. Spreadsheets and paper slips are no longer enough: Manual warehouse management wastes too much time, and human errors (like incorrect orders) happen too frequently.
2. Operations are scaling: Order volumes are growing rapidly, making faster order picking necessary.
3. Omnichannel sales create complexity: You are selling from the same inventory across an e-commerce platform, physical retail stores, and wholesale channels—requiring real-time, automated inventory synchronization.

In short: A WMS saves time, minimizes errors, and makes warehouse workflows so intuitive that new employees can hit the ground running from day one.
