Answer: cash budget
Explanation: A cash budget is indeed an approximation of a companies cash flow throughout a specified number of years. Such a budget is also used to determine whether the company has enough cash to function.
Organizations use revenue and output estimates to construct their cash budget, together with projections about both the expected expenses and records of receivable accounts.
To determine how well a business will have sufficient capital to maintain activities, a cash budget becomes required. When a firm doesn't have sufficient liquidity to function, more equity must be raised by granting stock or bringing on more loans.
