Reference excerpt

In inventory management, a stock keeping unit (abbreviated as SKU, pronounced es-kay-YOU or SKEW) is the unit of measure in which the stocks of a material are managed. It is a distinct type of item for sale, purchase, or tracking in inventory, such as a product or service, and all attributes associated with the item type that distinguish it from other item types (for a product, these attributes can include manufacturer, description, material, size, color, packaging, and warranty terms). When a business records the inventory of its stock, it counts the quantity it has of each unit, or SKU. SKU can also refer to a unique identifier or code, sometimes represented via a barcode for scanning and tracking, which refers to the particular stock keeping unit. These identifiers are not regulated or standardized. When a company receives items from a vendor, it has a choice of maintaining the vendor's SKU or creating its own. This makes them distinct from Global Trade Item Number (GTIN), which are standard, global tracking units. The Universal Product Code (UPC), European Article Number (EAN), and Australian Product Number (APN) are special cases of GTINs.

Meaning in software SKU is also used in software and software as a service (SaaS), including cloud computing. Cloud service providers such as Google Cloud Platform present different purchasable variations of the product or service as SKUs.

Worked examples

Example 1 — a first encounter with Stock keeping unit

Start with the simplest possible case. Write down what Stock keeping unit claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Stock keeping unit before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Stock keeping unit ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Stock keeping unit

In research: Stock keeping unit appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Stock keeping unit in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Stock keeping unit is common in secondary-school and first-year university syllabi. It links to neighbouring topics Business stubs, Inventory, Product classifications, so understanding it makes those chapters shorter.
In everyday life: Look for Stock keeping unit outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
