Sell products in one unit (e.g. carton of 24) while tracking inventory in another (e.g. individual bottle). NinoPOS handles the conversion automatically at sale time.
Products → Units. The base unit is what you count in stock — usually the smallest sellable unit (bottle, kg, piece).
Per product, add additional units with a conversion factor. e.g. base = bottle, sales unit = carton, factor = 24.
You can either: (a) price the base unit and let cartons auto-multiply, or (b) override carton price for volume discount.
At POS, pick the unit at line-add time. Inventory decrements correctly (sell 1 carton → stock drops by 24 bottles).
