Why the balance sheet is showing profit whereas my bank account balance is zero ??

in the classical financial reporting companies were relying on balance and Income statement to understand the financial indicators , but this not enough , the need creates three road combining balance sheet and income statement . You have to reconcile your nominal profit to hard cash to understand how the company is managing the cash issue . Three sources of cash generation and application are agreed . Operating , investing and  financing , by mapping three categories with cash in/out gives us pictorial picture and answering the question from where the firm gets its cash and how it  disposes it . We have now what we call it the statement of cash flow , earlier it was called statement of changes in the financial statement .

Because the finance manager is aggressive and make use of the available money in making investments that generate profits but reduce liquidity.
