As a business owner, it seems as though there aren’t enough hours in the day. As a result, it makes perfect sense to take shortcuts when you can find them. For example, you are paying business bills…it’s late, you’re tired, and you realize that your home mortgage is due. So you pay it using the business checking account. Another example is using the business credit card to pay for personal expenses, like trips to the grocery store or filling up your vehicle with fuel.
