1. SPU (Standard Product Unit), standard product unit (SPU formed by common attributes and collections of commodities)
SPU is the smallest unit of product information aggregation, and is a collection of reusable and easy-to-retrieve standardized information, which describes the characteristics of a product. In layman's terms, a product with the same attribute value can become an SPU.
Information aggregation: It means that the information with recognition degree is used as the distinguishing point of different SPUs; not all attributes, the attribute value used is the key attribute value that can be distinguished;
Easy retrieval: The two descriptions of information aggregation and easy retrieval are achieved through the aggregation of key attributes + attribute values. The purpose of easy retrieval is achieved; the purpose is related to the usage scenario, not forever; which attributes and attribute values will be selected as The key attributes of distinguishing SPU will change with the scene; but for some scenes, there is a consensus; for example, for e-commerce sales, brand + model + key attributes are basically selected for standard products; this is also the explanation I got many years ago .
2. SKU (Stock keeping unit), inventory unit (specifically describe product attributes)
SKU is the unit of measurement of inventory in and out, which can be in pieces, boxes, and units. SKU is the smallest unit of inventory that is physically indivisible. According to different business forms, different management modes are processed.
SKU is the smallest unit of inventory that is physically indivisible. When in use, it should be handled according to different business types and different management modes. For example, there are 50 cigarettes in one cigarette, ten boxes in one cigarette, and 20 cigarettes in one box. These units have to set SKUs according to different needs. For example, warehouse wholesale hypermarkets must be set according to one box. Ordinary hypermarkets must be set up according to the rules. Tobacco and liquor stores must be set according to the box. In the past, street shops in Shanghai and other places must be set up by one. Such a cigarette is the smallest retail unit of cigarettes, but it should be set according to its own business and service mode. (The example of cigarettes is very good. I saw it on the Internet, but I can't find the source. If someone who knows tells me, I will add a quote);
It can be said that SPU is "style" and SKU is "number of pieces". As shown in the figure:
