i use paypal how can wuickbooks help me?

Why did you get QB? QB can give you a P&L and Balance Sheet, and track all your expenses as well as income -- Paypal will can handle your income, and your expenses if you pay by Paypal, but it won't be in P&L form. Your business should have more than income and expenses: you should also have balance sheet accounts to track. What do you give your tax preparer at year end? What you get from QB depends on what you need it to do.
