I am fairly new to TimeSlips and am using Ver 2013. I am billing a client for two separate tasks on one invoice. I need to apply a courtesy discount to one of the tasks and show the discount applied.

The invoice, billed by task, is billed using Arrangement 1 (tasks)  My issue is that I need to show a discount for one of the tasks. I read where I can add this credit to AR, but the process was not clear.

Any help will be appreciated.
