Another reason why you need to print off your paypal sheets is to keep track of your subscriptions and expenses. If you wait months and months (like I did this year) then you have no idea what you are wasting money on. Yes, I did want those subscriptions and I will use the PLR or ebooks, eventually, but they hurt my bottom line right now when they are only expenses and never bring income.
Keep track of your paypal account so you can limit your unnecessary expenses and improve that income.
