Cash flow is an ever-moving thing for businesses. Be ready for anything. For a business to be successful, it needs to have a good cash flow plan. This cash flow plan will contain forecasts as well as shortfalls in management. Forecasts give amounts of money that will be flowing in and out of a business, while shortfall management helps a business to have a strategy for times when cash will be in short supply. When both of these are included in a cash flow plan, they enable a business to be able to handle both extremes of cash flow, making it a success.
