As the name suggests, a receipt book consists of multiple detachable forms that serve as proof of payment. These booklets are usually pre-numbered chronologically and have the receipt headings in place. You can easily print out a receipt book template online or buy one at any office supply store.

A receipt book is a critical document because it helps you keep track of your financial transactions and serves as solid evidence for tax purposes. 

The number of individual receipts in a book can vary from 50 to 200 sets. Commonly, one set of receipts contains two different colored receipts: white and yellow.
