Steps Needed to Add Unit pricing to Invoices

Good afternoon!

One of our clients in requesting unit pricing on the invoices we send to them. I understand that there is a code to add in order to do this. Can someone tell me the step to find this code that I need to change and what I need to add to make unit pricing appear on the invoices? Thanks for your help!
