What is SPU (Standard Product Unit)?
SPU standard attributes are the basic attributes of goods. The two most core attributes of the basic attributes are brand and model. E-commerce platforms generally use brand and model to determine the SPU (Standard Product Unit) standardized management unit.
For example: Xiaomi 10 is an SPU, and mate50 is also an SPU. This has nothing to do with the merchant, nor does it have anything to do with the color, style, or package.
What is SKU (Stock Keeping Unit)?
SKU SKU (Stock Keeping Unit), if the standard attributes are determined, once the sales attributes are determined, then the SKU (Stock Keeping Unit) inventory measurement unit can be determined.
For example: it can be understood as physical goods in the warehouse. Each SKU has an inventory quantity and a price corresponding to it. Common sales attributes of e-commerce include color (Haoyue Silver, Dark Green, Blue), capacity (128g storage, 256g storage), etc.
For example, if the key attribute brand is Huawei, the model is mate50, the sales attribute colors are black and blue, and the capacity is 128G and 256G, then there are four SKUs:
Huawei mate50 black 128G
Huawei mate50 black 256G
Huawei mate50 blue 128G
Huawei mate50 blue 256G
What is SN (Unique Identification Number)?
The information of each mobile phone can be traced and is equivalent to the serial number of each mobile phone.
SPU, SKU, SN instances?
Business summary

A type of SPU with the same characteristics, the specific physical object (the physical object can be single or combined) is called SKU, and which specific physical object is SN.
The relationship between SPU and SKU is N:N, N:1, 1:N, which is determined according to the company's business model and service model .
SKU and SN need to be specific to inventory management
