What are a major advantage and a major disadvantage of the specific identification method of inventory costing?

A major advantage of the specific identification method of inventory costing is its accuracy, as it tracks the actual cost of each specific item sold, making it particularly useful for unique or high-value items. However, a significant disadvantage is its complexity and administrative burden, as it requires detailed record-keeping and tracking of each individual inventory item, which can be impractical for businesses with large volumes of similar products.
