A more thorough explanation:

A bill is a formal or public document that declares a claim against someone else. It can be used in different contexts:

An equitable bill is a legal document that presents a claim in a court of equity. It is similar to a declaration in law. For example, if someone believes that they have been wronged by another person, they can file an equitable bill to seek justice.

An invoice bill is a statement that shows how much money one person owes to another. For example, if you buy something from a store, they will give you an invoice bill that shows the price of the item and any additional charges.

A legislative bill is a proposal that is presented for debate before it becomes a law. For example, a member of Congress can introduce a bill that proposes a new law or changes to an existing law. The bill will be discussed and voted on before it becomes a law.

Examples:

• John filed an equitable bill against his neighbor for cutting down his trees without permission.
• The company sent an invoice bill to their customer for the products they purchased.
• The senator introduced a legislative bill that would increase funding for education.

These examples illustrate how a bill can be used in different situations to make a claim or propose a new law. Whether it is a legal dispute, a business transaction, or a political issue, a bill is a formal way to communicate a message and seek a resolution.
