Items, colours and sizes
Every item in Lean can carry a colour and a size, and belongs to an item group (trousers, shirts, jackets …) with its own default values for unit, VAT and margin. A style in four colours is four items in the same group, each with its own stock and price.
Behind each garment there can be a bill of materials: the fabric, the lining, the buttons, the label and the hours per workstation. So Lean knows how much material a sold piece requires.
