Single Order Picking is an order picking method in which one order is picked completely and independently of other orders, without grouping multiple orders together.
In single order picking, each order is processed independently of others. This means that all required items for one order are picked sequentially, without considering multiple orders at the same time.
This method is the simplest form of order picking and is often used as a starting point in warehouse organization.
In practice, the worker receives a single order via a system or a pick list. They then move through the warehouse and pick all required items in the specified sequence.
After completing the order, it is processed immediately—for example, packed or shipped—before the next order is started.
Even though single order picking is relatively simple, a Warehouse Management System (WMS) can significantly improve the process. It provides digital pick lists, optimizes travel paths, and reduces errors through scanning or verification mechanisms.
Especially in growing warehouses, a WMS is often the first step in transitioning from manual processes to structured order picking.
The main advantage is clarity and low error susceptibility. Since only one order is processed at a time, mix-ups are rare.
However, this method quickly reaches its limits as order volumes increase. The many travel paths lead to inefficient processes, which is why single order picking is often replaced by other methods in larger warehouses.
Single order picking is mainly used in smaller warehouses, in industrial settings, or in spare parts logistics, where orders are often individual and less standardized.
