Every business, no matter the industry or size, needs to have accurate financial statements. But just having financial statements doesn't do much good. You need to understand and use them. Every major business decision should be based on the information in your financial statements.
If you're only using financial statements as part of your taxes or to get a loan, you're making a big mistake.
If you want to have a successful business you need to be familiar with your financial statements. This is a great place to start on your road to success in business.
