First, the concept of spu

SPU = standard product unit (standardized product unit)

SPU is the smallest unit of commodity information aggregation, and it is a set of reusable and easy-to-retrieve standardized information that describes the characteristics of a product. Generally speaking, goods with the same attribute values and characteristics can be called SPU.

Second, the concept of sku

SKU = inventory unit.

SKU is the unit of inventory in and out measurement, which can be based on parts, boxes, plates, etc.

SKU is the smallest physically inseparable inventory unit. When it is used, it should be handled according to different formats and different management modes. It is widely used in clothing and footwear.

Third, the difference between spu and sku

For example:

If you want an iPhone XS, the clerk will continue to ask: What iPhone XS do you want? 16G silver? 64G white? The gross weight of each iPhone XS is 420.00g, and the origin is Chinese mainland, so these two attributes belong to spu attributes.

Capacity and color will affect the price and inventory (for example, the price of 16G is different from that of 64G, and the silver of 16G and the gold are sold out), which are all sku attributes.
