Stock Keeping Unit (SKU): Definition, Best Practices, Example, and Benefits

What is an SKU?

The Stock Keeping Unit (SKU), often around 8 alpha-numeric digits, helps retail stores keep 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.

Unlike UPCs, SKUs can be designed per the retailer’s specific needs as they are not universal.

Stores, e-commerce vendors, warehouses, supermarkets, product fulfillment centers, and businesses dealing with inventories use SKUs. As a result, eCommerce giant Amazon uses SKUs extensively, requiring SKUs to be part of the inventory file that a seller submits to it.

SKU Benefits:

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 to tracking the product’s ownership and get the warranty information.

Barcode numbers on a group of products may differ for each product if one wants to provide them with a unique identity. However, SKU numbers remain the same to establish that they belong to a specific product group. Therefore, 1000 television sets of the same size and features will have the same SKU, whereas their barcode and UPC numbers 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 an SKU should be represented by the most important attribute of the product.
• SKU Numbers should not begin with zero as some software might consider zero values as null and remove them.
• The SKUs should not be aimed at being relevant with respect to the meaning, as they 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 naming 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 to 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

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.

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.
