One product, many sizes, one place to manage them.
A shirt in five sizes, oil in three tin sizes, or a spare part in two grades stays one product with several variations, each with its own barcode, stock and price band. It also holds the price-band data that quantity pricing reads.
Who it is for: Anyone whose products come in sizes, grades or pack counts.
Why it is included: Products, variations and units of measure: one product in several sizes, and the packs it arrives in. This is where a box of twelve becomes something the till can sell either way.
Included in the till. The base price covers it, so there is nothing extra to buy.
