How do you add a discount column for individual items on an invoice?

While there isn't a direct method to add a discount column for each item, we can create a service item specifically for the discount and apply it to each line item of the products you wish to discount, @deborah37.

To do that, let's create a service item for the discount with a negative rate and a description. For example, if you have a Labor Day discount of $50, you can add Labor Day Discount as a product or service, then enter a rate of -50.
