Define maintenance and other operating expenses?

Operating Expenses are expenses that are incurred while running a business. Maintenance Expense could be considered anything from the cost of maintaining a company vehicle to repairs made on a building or some other type of "maintenance" that is require by the business in order to function at 100%.

Many expenses have their own account such as, Utilities Expense, Rent Expense, Insurance Expense, Interest Expense, Supply Expense, just to name a few. Other expense may not have a specific account in which to be recorded, such as Travel Expense, Food Expense (perhaps to entertain a possible client), these expense are often listed under "Other Expenses".
