You should definitely have an accountant and/or bookkeeper. This will be the go to person for information like this. If they are on top of things you should have an item like this available to you on a monthly basis so that it can be analyzed and monitored on a montly basis. Not knowing where you stand can be dangerous, without monitoring profits and losses your business can go belly up. As time (months) goes by without any knowledge you can dig yourself into a deeper hole not knowing that you were already in one.
