Billing System

Hi all,
I’m planning to start a new and simple project called Billing system.
I want to give a bill to customer. It should look some thing like this.

Qty Product Price Amount
2 Book 4$ 8
3 Pen 2 $ 6

     Total 14$.

This is a sample bill for one customer. So Is there any scaffolding to
do this in rails?? Or if not any simple method to do?? Please give me

Thanks and Regards,
