The case, not the product, is the unit of price
Food buyers compare case rates, and case rates are only comparable when the case is described. Units per case, unit weight, pack format, whether the rate is per case or per kilogram: these are not administrative details, they are the entire basis of comparison. A quotation that names a product and a number leaves the buyer to assume a configuration, and buyers assume generously in their own favour.
The same discipline protects the supplier when a buyer asks for a different pack. A rate held against a defined case can be recalculated for a smaller one. A rate held against a product name cannot, and the recalculation becomes a negotiation in which the original figure is treated as a ceiling.
