An accounting system that measures the cost and performance of specific activities performed within an organisation.

For example, an ABC approach might measure the cost incurred by the accounts receivable department in handling calls for billing errors,

whereas the traditional accounting approach ignores the activity and measures

the cost of the accounts receivable department as a percentage of revenue.
