Accounts payable

For people who check facts
Accounts payable is one of a series of accounting transactions dealing with the paying of suppliers to which one owes money for goods and services. The average household performs this task by writing checks each month to such suppliers as the electric company, telephone company, cable TV or satellite dish service, the local newspaper, and so on.

Business organizations which have become too large to perform such tasks by hand (or who prefer not to do them by hand) will generally use accounting software on a computer to perform this task.

Other types of accounting transactions include accounts receivable, payroll, and trial balance.
