Answer:
An unearned revenue
Explanation:
Cash received before services are performed is commonly known as a cash advance or a customer advance. It involves a debit to Cash and a credit to a liability account like Cash Advances, Customer Advances, Unearned Revenue, or Deferred Revenue.
Conversely, an accrued revenue is the opposite of an unearned (or deferred) revenue. Accrued revenue occurs when services are performed before cash is received. This results in a debit to Accounts Receivable (an asset account) and a credit to Service Revenue.
