What is a Stock Keeping Unit (SKU)?
Businesses use a special code called a Stock Keeping Unit (SKU) to identify and monitor every product code in their inventory. SKUs are usually alphanumeric combinations that stand for particular attributes of a product tracking code, like its category, size, colour, and brand. For instance, a retail establishment might assign a blue medium-sized shirt the SKU “SHRT-BLU-M.”
SKUs are important because they make it simple for companies to monitor inventory levels, sales trends, and restocking requirements. Many businesses use inventory management software to automatically issue and track SKUs within a structured framework to ensure these numbers are used uniformly throughout activities.
The Importance of SKU in Inventory Management
SKUs are essential inventory identifiers because they make tracking and arranging things precisely possible. Businesses can better organize their inventory by classifying products according to factors like kind, size, and colour by giving each item a unique SKU.
SKUs give businesses information about reorder points, track inventory movement, and demonstrate what they have in stock. When getting ready for holidays or sales, vendors might use SKU data to determine what they should replenish. SKUs provide information that lets businesses know where a particular item is in the shipping process.
How are SKUs Created?
Developing successful SKUs necessitates adhering to rules that guarantee scalability, uniformity, and clarity. Companies should concentrate on creating SKU identifiers that are brief—typically 8–12 characters—and sufficiently informative to communicate important product information. For instance, a store might use “JKT-BLK-L” for a large black jacket.
When product catalogues grow, manually managing SKUs can become too much to handle. By automating SKU creation, inventory management software provides an effective solution. Businesses can swiftly establish consistent SKUs by using predefined templates that are based on variables like size, colour, or kind.
Where are SKUs Used?
Various businesses frequently use SKUs because they make it simple for employees to find products and monitor stock levels, which helps retailers manage huge inventory. Let’s take a look where SKUs are frequently used in:
- Inventory management systems: SKU numbers are kept in point-of-sale (POS) or inventory management systems, which facilitates tracking every product.
- Warehouse shelving: SKUs are frequently labelled on warehouse shelves to help employees quickly locate products during picking and packing.
- Product listings: SKU numbers are included in product details on e-commerce sites like Amazon and eBay to guarantee customers receive the correct items from the finished goods inventory list.
- Shipping labels: SKU numbers are frequently printed on shipping labels from companies to facilitate product tracking and identification during delivery.
- Delivery notes: To guarantee precise order fulfilment, SKUs are frequently mentioned on delivery notes as a clear reference to the supplied product.
- Price tags: Retailers frequently use SKU numbers on price tags to help employees locate items in-store and manage inventory effectively.
- Receipts: The SKU number is usually listed on the receipt and the product description when a product is sold.
- Product packaging: SKU numbers are printed by manufacturers on product packaging, usually either directly on the package or on a label.
Regardless of the sector, companies with extensive product catalogues can benefit greatly from the additional accuracy, ease of tracking, and operational efficiency that comes from integrating SKUs with an inventory management system.

SKU vs. UPC: What’s the Difference?
SKUs and UPCs (Universal Product Codes) have different uses. SKUs are separate codes that each company creates to keep track of and arrange its items. For instance, “TSHRT-BLU-M” may be the SKU for a medium blue t-shirt in a clothes retailer. Conversely, UPCs are standardized codes, such as “012345678905,” used to identify products worldwide and are the same for all shops.
The primary distinction is customization: UPCs remain constant regardless of the product’s location of sale, whereas SKUs are customized to match a company’s unique requirements. For example, even if a t-shirt is sold online or in many retail chains, it always has the same UPC, even though it may have the SKU “TSHRT-BLU-M” at one store.
Companies typically utilize UPCs to sell products across several platforms and SKUs for internal tracking. Numerous inventory management systems can manage both, which facilitates product management and organization across various sales channels.
How are SKUs Used in E-Commerce?
SKUs are essential for maintaining the organization of online stores and guaranteeing precise order fulfilment in e-commerce. SKUs manage sales data across platforms, track inventory, and classify products.
For instance, the SKU assists in finding the precise item in the warehouse when a consumer places an order, guaranteeing that the right product is received. Businesses link SKUs to every listing on sites like Shopify and Amazon to monitor inventory and automatically refill when supplies run short.
For e-commerce specialists, SKUs are essential for backend process optimization and go beyond simple identification. High-volume retailers utilize SKUs to help them in reducing fulfillment errors and arranging product variations.
Inventory management software further improves this by automating reorders, syncing SKUs across platforms, and offering real-time data. SKU data is essential to effective scaling and profitability in advanced e-commerce operations, which also uses it to estimate demand, track top sellers, and adjust marketing tactics.
