When you know the profit margin of each product or service that you are selling then you will know which is the most profitable, and you can spend more resources promoting that item.
2.  Trim unnecessary costs
Runaway costs are the most common reason for money leaks in a business. To be as profitable as possible, costs need to be controlled. Regular monitoring of your costs ensures that you prevent budget overruns because it allows you to identify issues before they turn into big problems.
3.  Increase your profit margins
A profit margin is a ratio that demonstrates how much profit a sale of an offer leaves you before paying taxes. By breaking down the costs of each product or service that you are selling you will understand what drives your profit margin up or down. 
4.  Invest in your business
If you aren’t sure how to understand your numbers, invest the time in learning this skill. The return on investment will pay itself many times over through the proper management of your business finances.
5.  Understand that each decision you make affects the bottom line
Every business decision you make impacts your bottom line either directly or indirectly. When you understand how your business decisions are affecting your bottom line, you will make smarter business decisions that keep the profit in the business.
6.  Know your cash flow
Cash flow is one of the most important areas that keep you in business, so monitoring your cash is very important. If you can’t pay your bills, you won’t stay in business for long. You need a good cash management system so that you’ll know what bills you have coming up, and if you have enough cash in the bank to cover them. This allows for proper planning and if a potential problem arises, you can be aware of the fact before you start losing sleep over it and allows you to be proactive.
The bottom line is, although sales are most definitely important when running a business, they are not the determining factor to success. Success lies in the ability to manage expenses to ensure you are not spending more money than is being generated. When you know your business numbers, you can better understand what your financial reports are telling you and make timely informed decisions.
