 In this discussion we will discuss the discussion question of discuss a voucher system and how it can work. When we're thinking about a voucher system we're typically thinking of internal controls this time on the payment side of things. So we're talking about cash going out for purchases typically and we want to make sure that we have a system of the controls in place here. This is a place where much of a fraud takes place within the cash leaving the company and there's various ways that you know we might make checks or purchases that aren't actual business purchases and that type of thing or fictitious purchases in the purchasing side of things. Therefore, we need to have a really good system on this side in order to check against that problem. Now again this will change a lot as we grow. If we're a small company we probably have the owner of the company very involved in all the purchases, signing all the checks, possibly doing the bank reconciliation.
