Cash normally means bills and coins, as in paying in cash.
However, the term is used in a business plan to represent the bank balance, or checking account balance.
LivePlan builds its financial analysis around cash and cash flow used in this second sense, as the balance of the checking account in the bank, plus other liquid securities used to bolster the checking account.
