What is SKU?
SKU stands for stock keeping unit and it's a number that retailers and businesses use to differentiate products and track inventory levels. It’s not enough to have one SKU for a shirt.
Each product variant should have different SKUs to manage. In the case of the shirt, you’d need a unique SKU code for different colors, brands, patterns, and sizes.
SKUs aren’t universal they have unique identification of each of the variants that are present in your inventory. Always it's a number that retailers assign to products to keep track of stock levels internally and easy to understand which items will be out of stock.
Why are SKUs important?
SKU numbers are important because they help you to track your inventory accurately and prevent out-of-stock and also pinpoint when to order new products so your merchandise never goes out of stock.
SKUs also help to collect data on sales. For example, a store can see which items are best selling and which are not based on SKU data.
