SKUs

The Stock Keeping Unit (SKU) Attribute is a unique numerical identifier that relates the purchase to an actual physical object.

A SKU is always associated with a product. It represents a physical item in inventory, and contains a number of SKU-specific Attributes, including:

• Unique ID

• Price

• Description

• Inventory Quantity

• Brand/Manufacturer

• Material

• Color

• Gender

• Physical Properties including, dimension, weight, size

Note that the Attributes for each SKU can be used by many different SKUs.

The following table shows examples of SKUs for a variety of unrelated products.

In the above example

• All three cotton t-shirt SKUs could belong to a single product.

• All four shirts could belong to a Product Category called: tshirt.

• The television could belong to the Product Category: TV & Video/Televisions.

Multiple SKUs

A product can have multiple SKUs associated to it. Creating products with multiple SKUs facilitates the management of product details and inventory management.

For example, a customer might want to purchase a "men's white cotton t-shirt". If the product is defined by multiple SKUs then the only choice the customer needs to make before purchase is the size. At checkout time they choose from an enumerated list of sizes (S, M, L, XL, and XXL) to narrow the choice to a single SKU. There also might be additional SKUs for properties such as color.

User Level SKU Attributes

Customers using the front-end website can also define Attributes. An example is when a customer purchases a gift card. Attributes can be applied to the SKU for the card, specifying who it is from, who it is for, or a personalized message.
