Products & Catalog

Term Definition

Product Any item you buy, stock, or sell. A product can be standalone, a parent with variants, or a kit.
Variant A specific version of a product offered in options such as size or color (for example, a large T-shirt). Each variant belongs to a parent product.
Parent product A top-level product that groups its variants together. Variants can inherit pricing, weight, and dimensions from their parent.
Kit / Bundle A product sold as one SKU but made up of several component products. See Kits and Bundles.
Component A product that is part of a kit. The kit records how many units of each component it needs.
Price tier A price that applies at a given order quantity, used for volume or wholesale pricing (for example Retail, Wholesale, Bulk). See Price Tiers.
Custom field An extra, company-defined attribute on a product — text, number, yes/no, or image — for data the standard fields don't cover. See Custom Fields.
Product group A label you assign to products to organize the catalog (for example "Seasonal" or "Clearance"). A product can belong to many groups.
