Planning and monitoring a budget is an invaluable tool to help control, prioritize, and manage business finances. It helps reduce waste, adapt to change, and achieve financial goals by providing a summary of likely income and expenses for a given period. Budgeting methods include zero-based, top-down, and bottom-up approaches and can focus on factors like sales, costs of sales, overheads, capital expenditures, and cash cycles. Professional assistance is available to help businesses with budgeting.
