Business budget categories are a way of organizing expenses and revenue in order to gain insight into the financial health of an organization. A business budget can be divided into different categories according to key areas of focus, such as sales, marketing, operations, research & development, and human resources. Having a clear plan for your business budget can help you better track where money is going and coming from, anticipate future costs or revenue streams, and identify potential issues before they become too costly. With careful budget planning, businesses can maximize their profits and increase their efficiency.
