Expenses are usually divided into two sections: direct costs, or cost of goods sold, and expenses. Cost of goods are those that are directly linked to the provision of services or sale of goods. For example, if you buy widgets from a wholesaler and sell them at a marked-up value, the cost of the widgets is a direct cost, not an overhead expense.

Other types of direct costs might be importing and freight costs, contractor costs or certain equipment. Some direct costs are fixed, that is, they are the same from month to month, or they could be a fixed percentage of sales; others vary in value but are still related to the income producing activities.

Overhead expenses are all the other expenses required to run the business, regardless of the level of income: for example, rent, utilities, bank fees, bookkeeping fees, professional development costs, vehicle costs and staff costs. Many of these costs form the basis of working out your break-even point, or how much it costs just to open the doors for business.

There are some expenses which may be reported as a direct cost in one business but an indirect cost in another type of business, for example, merchant fees or contractor costs.
