We currently rent a boiler to replace one that was broken be on repair and had exceeded it's useful life. How can I show the monthly cost of $8,500.00. I currently use a monthly work order pivot chart to show higher ups cost per building. If I use an open extended work order would that show the monthly cost. I use completion date as one of my constantans. I could put in a work order each month with the cost. Any thoughts or comments?
