Revenue recognition is a generally accepted accounting standard (GAAP) that identifies and accounts for the exact criteria under which revenue is recognized. The revenue recognition principle, which is a component of accrual accounting, states that revenues should be recognized on the income statement in the period in which they are realized and generated rather than when cash is received. When evaluating line items on the income statement, having a uniform revenue recognition rule helps to ensure that an apples-to-apples comparison can be made between organizations. To assess and review historical financials for seasonal trends or discrepancies, revenue recognition principles inside a corporation should also remain consistent over time.
