Buckeye Inc. uses the sales forecast to plan production. The company produces a glow-in-the-dark cup called "Lights-Out" one month in advance of the forecasted sale
The January sales forecast of 20 units of these cups will be scheduled for December production. However, the company also notes that sales forecasts and actual sales can differ, and the company has a policy of having 20% in inventory to accommodate sales above forecast. Raw materials for Lights-Out are acquired the month ahead (in this case, November). Wages are paid in the current month of production (December). Utilities are paid a month after production (January) and shipping is paid a month after the sale (two months after production, February). Finally, an inventory count reveals that there are currently 4 units on hand above the projected sales for November (at the start of November when the raw material order is placed).
