About inventory costing
Managing inventory costs is concerned with recording and reporting business operating costs. It includes the reporting of manufacturing costs and inventory costs, that is, the value of items.
Central principles to understand are that costing methods define how items are valued when they leave inventory, that cost adjustment updates the cost of goods sold with related purchase costs posted after the sale, and that inventory values must be posted to dedicated G/L accounts at regular intervals.
