Financial planning needs to spend more energy on specific analysis, including the preparation of cash flow statement, balance sheet and income statement. Liquidity is the lifeline of an enterprise, so when an enterprise starts or expands, it needs careful planning in advance and strict control in the process; The income statement reflects the profitability of the enterprise, which is the operating result of the enterprise after a period of operation; The balance sheet reflects the state of the enterprise at a certain moment, and investors can use the ratio index obtained from the data in the balance sheet to measure the operating status and possible return on investment of the enterprise. The financial planning of an enterprise should be consistent with the assumptions in the business plan. In fact, financial planning is closely related to enterprise's production plan, human resource plan and marketing plan.
