Deferred revenue is not yet revenue. It is an amount that was received by a company in advance of earning it. The amount unearned (and therefore deferred) as of the date of the financial statements should be reported as a liability. The title of the liability account might be Unearned Revenues or Deferred Revenues.
When the deferred revenue becomes earned, an adjusting entry is prepared that will debit the Unearned Revenues or Deferred Revenues account and will credit Sales Revenues or Service Revenues.
