To isolate SKUs, you first need to physically or logically separate the inventory. You can separate different SKUs by setting up specific areas or shelves in the warehouse, or create different inventory locations or labels in the inventory management system to identify and manage different SKUs.

At the same time, you can also ensure the isolation between different SKUs by setting up independent receiving, loading and shipping processes. In addition, establishing strict standard operating procedures and training employees are also important means to ensure SKU isolation. In actual operations, isolation measures need to be regularly checked and verified to ensure that different SKUs are not confused or cross-contaminated.
