Q. What is matching principle?

Expense recognition is closely related to as well as sometimes discussed as part of the revenue recognition principle. The matching principle states that expenses must be recognized (recorded) as they are incurred to produce revenues. An expense is the outflow or else using up of assets in the generation of revenue. Firms voluntarily acquire expense to produce revenue. For illustration a television set delivered by a dealer to a customer in exchange for cash is an asset consumed to produce revenue its cost becomes an expense. Likewise the cost of services such as labour is voluntarily incurred to produce revenue.
