What is it?

A Bill, also called an Invoice, is a document that lists the items or services you have bought and how much you need to pay for them. It acts as a record of a transaction between a buyer and a seller.

Simple Example

Quick Example

Imagine you go to a small shop to buy some biscuits and a packet of juice. The shopkeeper writes down 'Biscuits: ₹20' and 'Juice: ₹30' on a small paper and tells you the total is ₹50. This paper is a simple bill, showing what you bought and the total amount.

Worked Example

Step-by-Step

Let's say you buy school supplies:
1. You buy 2 notebooks, each costing ₹40.
2. You buy 1 geometry box for ₹120.
3. You also buy 3 pens, each costing ₹10.
---
Calculate the cost of notebooks: 2 notebooks * ₹40/notebook = ₹80.
---
Calculate the cost of pens: 3 pens * ₹10/pen = ₹30.
---
Add all costs together: ₹80 (notebooks) + ₹120 (geometry box) + ₹30 (pens).
---
Total amount to pay = ₹230.
---
This total amount and the list of items would be shown on your bill.

Why It Matters
