Common business expense categories are a way of organizing and classifying everyday costs associated with running a business. These categories typically include employee salaries, office supplies, advertising and marketing, printing and binding, travel expenses, rent and utilities, technology, shipping and handling, professional services, and legal fees. By categorizing your business expenses in this way, you are better able to track exactly where your money is going each month—which can help you plan for future investments and budget correctly. You’ll be able to rest easy knowing that you have full visibility into how you’re spending your hard-earned cash.
