General Expense, or G&E, is the standard acronym used to refer to any business expense that cannot be classified as either a production cost, administration cost, marketing cost, or research and development cost. G&E is generally accepted as an umbrella term for those expenses that are necessary for doing business but do not fit into the other cost categories. Examples of G&E include insurance costs, banking fees, travel costs, and janitorial services. It’s important to keep track of all G&E because they can quickly add up over time and have a significant impact on profitability.
