HOW TO INSERT ONE COLUMN TO SHOW THE COST BESIDES THE PRICE?

There is only one price in your invoice format right now, we will use it for our service cost, however,we will also need one more column to show our other costs like visa, 3rd party and etc for our customer's better understanding. So please kindly advise how to add one more cost, and then the two cost will be automatically sum. We understand that you have the option of cost in line, but we prefer vertical display, thanks!
