Cash flow refers to a business's cash inflows and outflows. Cash inflows include receipts from customers and loans. Cash outflows include payments to suppliers and workers. Cash flow forecasting predicts future cash inflows and outflows. Forecasts are important for new businesses, fast-growing businesses, and businesses with erratic sales to help plan for and manage cash needs. Negative cash flow occurs when cash outflows exceed inflows. Businesses can improve cash flow by reducing stock levels, increasing credit terms from suppliers, reducing credit given to customers, and increasing sales revenue. Elements of a cash flow forecast include receipts/sales revenue, payments/expenses, net cash flow, opening balance, and closing balance.
