You must make sure that as you record transactions in your accounting system, they are recorded to the proper accounts. For example, if you are preparing financial statements, your activity should not just be recorded to general income or expense accounts. Your activity should be recorded to specific expense (i.e. advertising, insurance, office, and supplies) or revenue (i.e. sales, interest and dividends, services) accounts. However, an easy trap to fall into is adding to many accounts, for example you would want an account for office supplies but it is not necessary to have subaccounts for every office supply provider a company uses. When you check your accounts, you should make sure that expenses are in the proper accounts, and revenues are recorded to their Yproper accounts.
