SKU stands for Stock Keeping Unit, the smallest uniquely tracked unit in a product catalogue. Every distinct combination of product, size, pack type, flavour, and sometimes even color is a different SKU. A dairy brand selling 500 ml toned milk pouch, 1 L toned milk pouch, 500 ml full cream pouch, and 1 L full cream pouch has four SKUs, not one product.

SKU hygiene is make-or-break for distribution. A typical Indian FMCG distributor carries 200-600 active SKUs; a dairy distributor manages 50-200. Each SKU needs its own MRP, selling price, HSN code, GST rate, shelf life, and barcode. Sloppy SKU masters are the single biggest source of billing errors and scheme miscalculations.

Proper order management platforms treat the SKU master as a governed asset, only authorized users can add, retire, or change attributes, and every change is versioned for audit.

What Creates a Separate SKU

Several attributes each generate a distinct SKU, and they multiply rather than add. Pack size: a 100 ml, 200 ml and 500 ml bottle of the same shampoo are three SKUs. Variant or flavour. Packaging format, so the same biscuit in a pouch and a carton are separate. Promotional configuration, since a combo or festival pack must be stocked, priced and reported separately. Three sizes times four flavours times two formats is twenty-four SKUs from what marketing calls one product.

SKU vs Barcode vs HSN

An SKU code is internal, and the same physical product carries different SKU codes at the manufacturer, distributor and retailer. An EAN or UPC barcode is externally assigned and globally unique. An HSN code is a tax classification under GST, and many distinct SKUs share one. Confusing the three is a routine source of reconciliation error.

Why SKU Count Drives Margin

Every SKU requires a minimum stock holding regardless of how slowly it sells, so a slow SKU adds inventory that never turns. In a typical portfolio the bottom 40% of SKUs contributes under 5% of revenue while occupying working capital, godown space and most of the expiry risk. Our guide to SKU meaning and rationalisation sets out the method for cutting the tail.

Real-world example

Amul Butter 100 g carton and Amul Butter 500 g carton are two different SKUs even though they are the same product.

SKU (Stock Keeping Unit): common questions

The questions people ask most often about sku (stock keeping unit) in Indian distribution.

SKU stands for Stock Keeping Unit: the smallest distinct item a business tracks separately in inventory. Two products are separate SKUs if they differ in any attribute that must be counted, ordered or reported separately.

An SKU code is internal to a business, so the same product carries different codes at the manufacturer, distributor and retailer. A barcode such as an EAN or UPC is externally assigned and globally unique, so it is the same everywhere.

Yes. A 100 ml, 200 ml and 500 ml bottle of the same shampoo are three separate SKUs, because each must be stocked, priced, ordered and counted separately. The same applies to flavours, packaging formats and promotional packs.

Anywhere from a few hundred to several thousand, depending on how many brands and categories are handled. Multi-brand distributors in general trade commonly run into the low thousands.

Every SKU needs a minimum stock holding regardless of how slowly it sells, so slow SKUs tie up working capital that never turns. They also consume godown space and picking time and carry most of the expiry risk, while the bottom 40% of a typical catalogue contributes under 5% of revenue.
