Receipts are vital to successfully running a business. You need receipts to track your purchases and expenses. Your clients need receipts for their tax purposes and to manage their finances. Paper receipts have been around a long time, so many people are used to them and may even be resistant to moving away from them.
Thanks to technology, paper receipts are becoming more a thing of the past. There are environmental reasons for the move. Paper receipts require millions of trees and billions of gallons of water to produce, and they emit carbon dioxide (CO2), so going paperless can be a good thing for the environment.
