Prepaid Expenses
Amounts paid in advance for goods or services the business has not yet consumed, carried as a current asset and released to expense as the benefit is used. Annual insurance premiums, software licences and advance rent are the usual cases.
Deferred Revenue
Cash collected from a customer before the goods or services have been delivered, held as a liability until the obligation is met. Standard for subscriptions, annual plans and deposits. Recognised as revenue progressively as delivery occurs.
Unearned Revenue
Another name for deferred revenue: a customer payment received in advance of performance, carried as a liability because the business still owes the goods or services. It becomes revenue only once the obligation is satisfied.
Bad Debt
A receivable the business has concluded it will not collect. Recognised either directly as an expense when a specific invoice is abandoned, or through an allowance for doubtful accounts that estimates losses in advance.
