Order picking is one of the key processes in a warehouse.
Order Picking Process
Errors and delays during order picking directly affect customer trust and lead to losses, especially at high operational volumes.
DIONYSOS WMS solves these challenges: the system guides warehouse staff at every stage, automatically applies FIFO or Optimized order selection and FEFO stock picking, logs all actions, and ensures full process transparency, allowing orders to be picked faster and with higher accuracy.

*All actions are securely linked to the user, ensuring controlled access and full traceability.
Clear and user-friendly handheld terminal interface
The WMS interface is optimized for handheld terminals, enabling you to:
Train new employees quickly
Work according to unified standards across the entire team
Minimize manual actions and reduce errors
All you need is a handheld terminal. The system automatically guides the next steps.
Order picking under full control
Using a handheld terminal with a built-in scanner, warehouse staff can:
Perform order picking in series (Series Picking)
Follow an optimized picking route
Clearly see on the screen where to go, what to pick, and in what quantity
Confirm every action by scanning the product, location, or container
Reduce errors and standardize the picking process
Perform all actions in real time, with immediate system confirmation
03 · Workflow
How is order picking organized in DIONYSOS WMS?
Order picking in our WMS follows a strictly defined workflow.
All actions are performed by the operator via a handheld terminal and are controlled by the system at every stage.
Step 1. Receiving a picking task
Before starting work, the employee is automatically assigned the next available picking series.
The handheld terminal displays:
Picking series number (Series Picking)
Picking type: Mono, Multi, or Assembler
Warehouse movement route
Step 2. Executing the picking process
During picking, the system sequentially guides the employee through all required actions.
The handheld terminal displays:
Exact storage location of the item
Full product information
Required picking quantity
Each step is confirmed by scanning the product, location, or container, depending on the picking type.
We support two picking methods: Traditional Picking and Fast Picking.
Fast Picking reduces the number of scans without compromising control.
Step 3. Completing picking and transferring to the next process
At the final stage:
The picking result is recorded
Containers are sent to the packing area
After all operations are completed, the system closes the picking task.
04 · Principles
What is the picking process based on?
1. Order selection
The system selects orders for picking based on predefined criteria.
Two algorithms are available:
FIFO (First In, First Out)
Orders are picked in the order they arrived, skipping any without available stock until it's resupplied. For strict, no-skip ordering, an optional stock reservation mode locks each order's stock on arrival, guaranteeing it's picked exactly in turn.
Optimized
The system automatically groups orders based on the most frequently repeated products within a picking series.
How it works:
- The system searches for orders with the status “Ready to be picked”.
- Checks product availability in the warehouse.
- Selects orders in batches.
- For Optimized: first identifies the most frequent products, then selects orders containing those products.
2. Stock selection (FEFO)
When a product sits in more than one position, the system decides which one to pick from first.
FEFO (First Expired, First Out): the operator is always sent to the position whose stock expires soonest, keeping inventory fresh and cutting waste.
If one position doesn't hold enough, the system automatically continues to the next-soonest batch until the order is filled.
3. Prioritization
The system determines which orders should be picked first.
Priority levels:
Urgent - critical orders
High - high priority
Normal - medium priority
Low - low priority
How it works:
When assigning a picking series to an employee, the system sorts orders by:
Status (in progress > new)
Priority (from high to low)
Picking type
Picking series ID
Picking series type
4. Filtering
The system filters out orders based on defined conditions.
- Sorts orders by priority
- Selects orders according to the chosen algorithm (FIFO or Optimized)
- Groups them into picking series for warehouse staff
This approach enables efficient tracking of the entire picking process, including order priorities, product availability, and employee routes.
05 · Picking series
Picking series types
Mono Picking
Mono Picking is designed for orders containing a single item and a single quantity.
This is the fastest scenario: minimum actions, minimum scanning, and maximum speed from warehouse to packing zone.
- One item per order
- Fewer scanning operations
- Faster transfer from picking zone to packing zone
Multi Picking
Multi Picking allows multiple orders to be picked simultaneously within one series.
The employee follows an optimized route, while the system clearly indicates which product should be placed into which container.
- Multiple orders in one picking series
- Optimized route for parallel picking
- Clear product-to-container assignment
Assembler Picking
Mass picking with precise order assembly.
Assembler Picking is used when it is necessary to pick large quantities of products first and then distribute them across individual orders.
- Mass picking before sorting
- Accurate distribution into individual orders
- Controlled order assembly process
