A Stock Keeping Unit (SKU, pronounced as "skew") serves as a distinct code for retailers to manage and monitor their inventory. This unique alphanumeric code provides key information about each product, including details like manufacturer, brand, style, color, and size. Essentially, SKUs help retailers efficiently categorize and track their diverse range of products.
