Wave Picking is a method for time-based control of order picking in which orders are organized into groups—so-called waves—and processed together.
In wave picking, orders are not processed continuously but are released in batches at specific times. This grouping is usually based on shipping times, priorities, or logistical requirements.
The goal is to better synchronize order picking with downstream processes such as packing and shipping.
In practice, the warehouse management system plans different waves, for example for various shipping windows throughout the day. All orders assigned to a specific wave are released for processing together.
Picking is often combined with other methods such as batch or zone picking to further increase efficiency.
Wave picking is highly system-driven. A WMS handles the planning and control of waves and ensures that orders are processed at the right time and in the correct sequence.
In addition, the system coordinates alignment with packing, shipping, and, if applicable, transport service providers.
A key advantage is the high level of planning reliability. Workloads can be managed in a targeted way and resources can be used efficiently.
However, this structure often comes at the expense of flexibility. Short-term changes or urgent orders are difficult to integrate into an ongoing wave.
Wave picking is primarily used in larger distribution centers and in e-commerce, especially where fixed shipping times or cut-off times must be met.
