First, figure out the difference between a product and a single product. For example, iphone is a single product, but when many merchants sell this product on Taobao at the same time, iphone is a commodity.
Commodity: Taobao is called item, Jingdong is called product, commodity refers to the commodity related to the merchant, each commodity has a merchant code, each commodity has multiple colors, styles, and can have multiple SKUs.
SPU = Standard Product Unit
SPU is the smallest unit of commodity information aggregation. It is a set of reusable and easily retrieved standardized information, which describes the characteristics of a product. In layman's terms, a product with the same attribute value and characteristics can be called an SPU.
For example, iphone4 is an SPU, and N97 is also an SPU. This has nothing to do with the business, and has nothing to do with the color, style, and package. Taking cosmetics as an example, the following picture is the SPU information given by Paipai Mall :
In the process of electronic product information, the characteristics of the product can be described by multiple "attributes and corresponding attribute value pairs". Commodities with identical “attributes and corresponding attribute value pairs” can be abstracted into an SPU. At the same time, these "attributes and corresponding attribute value pairs" are also solidified in the SPU and gradually standardized. Based on the product information structure of SPU, rich applications can be realized, such as the integration of product information and information, reviews, and other SPUs.
Ps: In this sense, I think it is most appropriate to build the product library for comparison shopping with SPU as the standard.
SKU=stock keeping unit
SKU is the unit of inventory in and out measurement, which can be in units of pieces, boxes, trays, etc. It is most commonly used in clothing and footwear. For example, a SKU in textiles usually means: size, color, style.
Some people also explained that SKU is the smallest unit of inventory. In the clothing industry, the normal situation is "single single color and single size". Domestic brands have "single single color" as a SKU, and some "single style". Color is regarded as one SKU, and several styles of a piece of fabric are regarded as one SKU. These are all misunderstandings.
At the same time, another concept is derived: SKC: single style, single color. If you have to use an analogy: SKC is an orange, SKU is an orange, but in any case, an orange is an orange, and an orange is an orange.
However, the SKU is the smallest unit of stock that is physically inseparable. In use, it should be handled according to different formats and different management modes. For example, there are 50 cigarettes in one cigarette, ten boxes in one box, and 20 in one box. These units need to set SKU according to different needs. For example, warehouse wholesale hypermarkets must be set according to a box. Ordinary hypermarkets must be set in accordance with the article. Tobacco and alcohol stores must be set according to the box. In the past, street shops in Shanghai and other places must have been set by one. Such a cigarette is the smallest retail unit of cigarettes. But it should be set according to your own business format and service mode.
Ps: Regarding what SKU and SKC are, you can refer to this blog by Mr. Afu .
[Summary]: SPU is a standardized product unit, which distinguishes varieties; SKU is a stock-keeping unit, which distinguishes single products; commodities refer to commodities related to merchants, which can correspond to multiple SKUs.
ARPU=Average Revenue Per User
ARPU focuses on the profit that the operator gets from each user in a period of time. Therefore, the more high-end users, the higher the ARPU. During this time period, from the perspective of the operator's operation, a high ARPU value indicates a high profit, and the benefits during this period are good.
