What it is
A cost sheet is the standard garment cost build-up: fabric, trims, decoration, CMT (labour), overhead, export-to-port, and margin roll up to an ex-factory and an FOB price. It is the real-life apparel cost sheet, computed from the style's own data.
How to use it
Open a style's Costing page, or create a cost sheet from a quotation line. Pull the fabric/trims/SAM from the style so you do not re-type them, confirm your factory rates, and read the FOB versus the buyer's target. A sheet stays Draft while you work on it; marking it Final (ready to quote) needs an approver's sign-off when your factory has that rule turned on.
