The ABCs Of Activities Based Costing | Modern Machine Shop

The essence of Activities Based Costing is linking activities to costs, then linking costs to jobs. Figure 1: The averaging inherent in flat-rate costing inevitably causes a shop to over- or under-quote about 20 percent of the jobs it bids on. These odds aren't good enough to keep today's job shop in the running, says Bill Starn.
