A four-step flow diagram traces costs through the cost accounting cycle. Raw inputs — direct materials, direct labour, and overhead — attach to each unit during production; completed units then move into inventory carrying their accumulated product cost. When a unit is sold, that accumulated cost is released to the income statement as cost of goods sold. The connectors make explicit that costs follow the physical movement of the product: they attach to each unit, units carry the cost forward, and a sale triggers the expense.
