Imagine if your car had no gas gauge. You would probably worry a lot about running out of gas because you weren't sure how much was available. When you know how much there is and how much you usually use, you can plan wisely and not worry about running out of gas. If you know for sure that there isn't enough coming in, instead of worrying, you can cut back to basics and find a way to bring in more. There's plenty of money out there.
Numbers are what business is all about.
Even for owners of very small businesses, there are bookkeeping services that can help you. It's worth the extra expense because if you don't get control of the numbers, you won't be able to build a profitable business. You may sustain a cash flow for a while, but eventually it will get out of hand. Remember, we said that your business is an extension of you. Therefore, if you aren't working well, neither will your business.
