Some types of services, such as insurance, are normally paid for before they are used. As you learned before, these prepayments are deferrals. Rent, interest, salaries, wages, utilities, etc. are the other examples of accrued expenses over time. Expenses incurred but not yet paid or recorded at the end of the accounting period are accrued expenses. Accrued expenses are the ones that are firstly incurred and not recorded as an expense until a future accounting period.
