1) Cashflow forecasting helps businesses plan for periods of surplus cash and address periods of deficit. It allows businesses to plan investments or financing needs in advance. 2) There are several ways for businesses to improve cashflow, including increasing cash sales, reducing credit periods for debtors, factoring debts, delaying payments to suppliers, reducing capital expenditures, and obtaining bank loans or overdrafts. 3) While these methods aim to increase cash inflows or decrease outflows, they also carry disadvantages like potential loss of customers, damage to supplier relationships, and increased interest costs. Businesses must evaluate multiple options while considering their unique circumstances.
