As a business owner, you need to remember about separating your business life from your personal life. One of the ways to accomplish this is to use your business credit cards and your personal credit cards separately. Every time you decide to purchase something for your business, make sure that you are going to use one of your business credit cards. If you plan to shop in a grocery store, which has nothing to do with your business, always use your personal credit card. Separating business and personal life will allow you to keep track of your cash flows. It will be also easier for you to keep track of your taxes.
