September 8, 2020What is a SKU?
The Stock Keeping Unit (SKU), most often being around 8 alpha-numeric digits, helps retail stores in keeping track of the items and their variants in the inventory.
Moreover, it lets a retailer know if he has the right products in stock when he needs them. After that, It helps to present physical inventory items in a way that employees and computers can understand and track.
In common parlance, it is also known as item code, item ID, item number, etc. SKUs are shortened versions of item descriptions, Therefore, they are more popular as item descriptions tend to have a longer length. Consequently, SKUs help quicken the data entry, inventory movement, management, and Point of Sale.
Most importantly, SKU numbers can be created manually by using merchandise management or through the point of sale (POS) software. After that, they are printed on the label of the product along with the Universal Product Code (UPC) and other information about the product.
Unlike UPCs, SKUs can be designed as per the specific needs of the retailer as they are not universal.
Stores, e-commerce vendors, warehouses, supermarkets, product fulfillment centers, and businesses that deal with inventories are using SKU’s. As a result, eCommerce giant Amazon uses SKUs extensively, and it requires SKU to be part of the inventory file that a seller submits to it.

Differences Between the Stock Keeping Unit (SKU), Serial Numbers and Universal Product Code (UPC):
- SKUs are internal, whereas UPCs are external.
- While SKUs vary in length between 8-12 characters, UPCs are always 12 digits.
- Stock Keeping Unit identifies the product characteristics while, on the other hand, the Universal Product Code identifies manufacturers and items.
- SKUs are alpha-numeric, and UPCs are numeric.
- While the Global Standards Organisation (GS1) issues Universal Product Code, SKUs are determined by the retailer and accompany a barcode.
On the other hand, Serial Numbers are used for tracking the ownership of the product and getting the warranty information.
Barcode numbers on a group of products may differ for each product if one wants to provide them a unique identity. However, SKU numbers remain the same to establish that they belong to a specific product group. Therefore, 1000 televisions sets of the same size and features will have the same SKU, whereas their barcode number and UPC number will differ.
SKU Management Best Practices:
Points to Note while Generating and Maintaining SKUs:
- Try following a scheme starting with letters as it helps numbers stand-out in a spreadsheet and allows them to differ in the pool of data visually.
- The initial letters of a SKU should be represented by the most important attribute of the product.
- SKU Numbers should not begin with zero as some software might consider the value of zero as null and remove them.
- The SKUs should not be aimed at being relevant with respect to the meaning, as it might end up forming very long numbers.
- Never use numbers that look like letters – ‘0’ can look like ‘O’ and confuse the person handling inventory.
- Decide upon a convention and follow it in the naming of all the products. The classification you decide should be maintained with uniformity to ease understanding.
- Try making SKUs short in length and of the same length so that you find more consistency in your database.
- Never use special characters while coding the SKUs as they may confuse the computers.
- As far as possible, avoid using seller SKUs as they are meant to be customized as per one’s own requirement.
SKU Coding Scheme:
SKUs can be made of details like:
- Gender for which the product is intended
- Brand of the product
- Category of the product
- Size of the product
- Colour of the product
- Type of the products
- Name of the product
- Pricing
- Department code
Stock Keeping Unit (SKU) Example:
For example, an apparel store can design its SKUs considering item characteristics like item type, item size, item material, and item color as follows:
Why are SKU Numbers Important?
1. Accurate Inventory Control
At times, Inventory Management Software can be a tricky thing to manage. Furthermore, while overstocking on a product can lead to cuts in profits due to increased carrying costs, on the other hand, running low on stock of products can lead to a loss in terms of potential business.
In short, stock-keeping units help to maintain inventory records up to date, which in turn enables you to maximize profits and achieve the business goal.
2. Forecasting of Sales
Having a proper database and record of physical products with the help of stock-keeping unit numbers helps you forecast your sales better. In short, you can easily see which products are selling well, selling fast, or probably selling slow. With all such data, it becomes easy to anticipate the requirements of stock and maintain it accordingly. After that, you must analyze products strategically. After that, you can take the required steps to help foster sales.
3. Facilitating Quick Shipment
Once an order has been placed, a timely shipment is essential. As a result, keeping track of inventory is a very important step. Therefore, SKUs make this very easy.
They help warehouses find the required product quickly. Moreover, warehouse keepers can find the exact product with accuracy. Meanwhile, products that have multiple variants can be sorted soon and placed in the warehouse on the basis of SKUs. Above all, whenever a particular product is needed, the database can be checked, and the exact location of the product can be known. As a result, this saves the hassle of finding products in big warehouses and helps in shipping orders as quickly as possible.
4. Better Customer Service
The customer service teams and physical-store sales teams can quickly locate the products for which queries have been brought up by the customers.
As a result, repeating orders, finding a product, and comparing product features are all made easy for customers by SKUs. In the case of vendors, they can quickly present to customers their needed products when SKUs are in place.
5. Earning Greater Profits
Stock Keeping Unit Numbers can help you maximize your profits. Furthermore, they help you know the products that are selling the most. Therefore, you must take strategic actions to maintain sales levels. Proper positioning of the products on both offline and online platforms to increase customer focus can be done. After that, SKUs help in providing suggestions as to ‘related products’ while making sales. Product suggestions help increase sales and, thereby, profitability.

FAQs:
Both are similar. Just that the SKUs are interpretable by humans, whereas barcodes require a scanner.
In short, SKUs of a product group having the same characteristics will have the same SKU, whereas Serial Numbers are unique for each product.
In order to create a SKU,
1st step: Identify product characteristics/attributes that you wish to track (Say, Colour, Size, Gender, Material, etc.)
2nd step: Assign an alpha-numeric code to each characteristic
3rd step: Link all such codes in a series, and you are done!
Retail stores of all types, fashion retail, shoes, jewelry, pharmacy, sporting goods, gift shop, or eCommerce giants like Amazon, use SKUs for inventory management.
SKUs help identify stock on hand, in-transit, and sales performance of items. Retail stores using point of sale systems and eCommerce platforms can also recommend related products to customers using SKUs.
Say, a customer wants to buy a medium-sized T-shirt with a round neck. When the item is punched onto a POS, the POS system can recommend that the same T-shirt is also available in white and blue colors. The same is true for eCommerce platforms.
