Why Use SKU in Inventory Management in E-commerce?

SKU numbers are used in both e-commerce and retail. There are several main reasons why e-commerce businesses use SKUs:

Achieve Efficient Inventory ManagementThe uniqueness of SKU in inventory management provides a way to differentiate between different categories of products. It also makes it easier for you to monitor and manage inventory status in real-time, and analyze individual product inventory levels, changes in storage locations, and sales, which also helps you make more informed decisions.
A clear SKU system reduces human error during picking, packing, and shipping.

Get SKU Product DataData is the basis for analyzing customer needs.
By adding SKUs to all your products, you can collect data from inventory out-of-stocks to better analyze and make changes to your best-selling and non-selling products.

Predict Future Sales TrendsSKU in inventory management enables segmentation and tracking of each specific product. Study the different performances of each product, observe the order value and quantity of different products, and analyze the preference trend of the target customer group.
From there, you can more accurately forecast future demand, so you can make inventory adjustments or adjust marketing strategies to meet customer demand.

Set The Product Inventory LocationWithout a system to fix and differentiate products, it is difficult to replenish inventory by ordering products in a timely manner. By assigning an SKU to each product, you gain a new level of inventory visibility and can quickly identify which inventory levels are below the tipping point of replenishment. You can also set automatic reorder points for each SKU.
By subdividing specific products through SKUs and fixing the location, you can accurately find the location during replenishment, otherwise, it will be a great waste of manpower.

How to Create SKU Numbers for Products?

SKUs are customized, and businesses can create SKUs based on their own set of conventions or rules.
Although SKU generators can be used to create SKUs, there are aspects that you need to decide on your own.
Here are some requirements to follow when creating an SKU:
Created According to the Standard Format of the SKU

Your business should establish a set of criteria for creating and assigning SKUs.

For example, what attributes the SKU catalog has, and how the order in which the attributes of the product information are presented. Such as product category, color, size, model, etc.

Make Sure Each SKU is Unique

The purpose of the only SKU in inventory management is to distinguish each product from all others, so two different products having the same SKU is not for the purpose. The exact same item may have two different SKUs in two different businesses.

Similar SKUs can be Used

One of the biggest benefits of SKUs is that they allow you to differentiate particularly similar items and sell them together on physical shelves and in online stores.

Differentiating similar products with similar SKUs not only keeps inventory organized, but also recommends alternatives to the same type of product to customers when they sell out of the goods they need, even if the customer is satisfied and the sale is completed.

Add SKU Product Basic Information

When creating an SKU system, remember to record the dimensions and weight of each SKU. Many businesses tend to skip this step, but it’s necessary to accurately estimate your inventory capacity.

Use the SKU Management System

SKU management systems can simplify SKU tracking over time and facilitate inventory counting. Whether it is for physical stores or warehouses, or for accounting purposes, it is very convenient.

Implement The SKU Software

Inventory management software can automate most SKU management processes and provide detailed visibility into SKU levels, assortment, order history, sales records, and shipping confirmations.

Finally, I would like to say that for SKU generators, although you can use the generator, it is best to write according to your own management habits.

Take the Amazon platform, whether you build new products or sell existing products, you need a corresponding SKU in inventory management, about the SKU writing rules, Amazon does not strictly require, the SKU column can be filled in by the seller himself, if not filled in, Amazon will automatically generate an SKU code assigned to you, although it is very trouble-free, this will make it difficult to identify. Therefore, in order to facilitate the management of products in the future, it is best for sellers to write SKUs according to their own management habits or product characteristics.
