Business planning is fundamental to any business. A well considered, structured plan which is regularly reviewed should include as a minimum a current pro-forma balance sheet, an income or profit-and-loss statement and a cash-flow analysis. In addition, the plan should provide specific information about the firm's debt levels and debt-servicing requirements, and how the firm will repay borrowed money. A good business plan is crucial for any business loan or credit (overdraft) application or extension. More detailed business plans would include information on management systems of the firm's operations and finance management, promotion and marketing, and goal and objective attainment.
