Accrued expenses represent expenses incurred but not yet paid by the company. When companies receive invoices for services or products they received, the money owed represents an accrued expense. The company records the expense when it receives the invoice. If the company will not receive an invoice until the following period, the accounting staff records a manual accrual entry increasing accounts payable and increasing the expense for the amount of the transaction.
