Accounting is a very important part of your business. Your business will not suceed if you don't have good control over how much money; you have, will need and how you are using your money.
Accounting uses an accounting system to record all the transactions (activity) of the business as it uses money and the things that were bought with money.
The term income statement is a report that covers a period of time and summarizes all the revenues (money taken in) and subtracts the expenses (money used) to come up with a difference which is Net Income, Profit or Earnings.
A Balance Sheet is a report at a specific date that summaries the assets (things that have a value), liabilities (money owed) and equity (difference between assets and liabilities). If you were to list the cost your toys, books, clothes etc. and the cost of them you would have a part of a balance sheet.
The success of most businesses is measured by the amount of money they make (profit) and how that relates to the amount of money that people have put into the business. If someone puts a lot of money into a business to get it started or to grow the business, then they expect to get a lot of money back.
If you asked someone or a bank to invest a $100,000.00 into a business; it is important that they know how their money was used and how much money it made for them.
