As a former LC operator I always made sure my money was right. It is important to keep your business funds and personal funds seperate IF you want your business to be a business and not a "summer job". I was looking the other day for some new info and found that quickbooks simple start is COMPLETELY FREE! They offer a free download on thier website and there are no obligations. The idea is to ge tyou to purchase the next level but there is no requirement. Quickbooks Simple Start is VERY easy to use and makes keeping up with money, creating billing invoices and recording expenses easy enough even for the financially challenged.
