What Is a Bill?

A bill refers to the amount of money a customer owes a business. It is a document that outlines the amount that a consumer owes for goods and services received and rendered. It is printed or written as a statement for the charges owed.

The purpose of a bill is to serve as legal evidence for both the buyer and the seller that a sales transaction took place.
