I recently started working at a small law firm that uses the 2016 version of Sage Timeslips. The person I replaced was not here when I started, so I was left to figure out how Timeslips works on my own. My question is regarding billing. Once the billing worksheets have been reviewed, I need to make some edits. For example, I need to apply discounts against what was produced in the billing worksheet. However, it seems that unless I approve the bill that needs the discount, the software does not have anything to apply the discount to. I'm sure there is a simple answer, but I've tried it a hundred different ways with no success. Can anyone tell me what I am doing wrong? Is it possible to add a discount before an invoice is generated?  Thank you!
