An SKU is the code that identifies a product variant uniquely inside the business. Unlike a barcode, the seller defines it and it is meaningful only in their own system; the warehouse, accounting, marketplace dashboard and integration software all speak through the same code.
In multichannel selling, once SKU uniqueness breaks, overselling is inevitable. Meaningful coding, for example a brand-category-color-size order, speeds up both warehouse work and reporting, but embedding price or supplier information in the code is wrong, because those change. Opening a separate SKU for sets and bundles requires defining in the integration how component stock will be deducted; without that definition, a bundle sale does not draw down the individual stock and the records stop reflecting reality.
