This document discusses terminology used in activity-based costing (ABC) systems. ABC assigns overhead costs to products based on cost drivers like purchase orders or machine setups. Unlike traditional costing methods, ABC assigns costs to activities first and then to products based on activity usage. ABC provides more accurate costing results than traditional methods by breaking down indirect costs, though it is more complex. For Jeemp Farms, ABC costing would be the best method since costing decisions have large profit implications.
