I have Quicken Classic For Mac Business and Personal, version 8.4. I need to be able to have invoice items that can have negative rates. I can set them up that way in Products and Services, but the negative value turns positive when I use it on an invoice, particularly when I tab through the rate field. Can the development team look into this? Secondly, it would be greatly helpful if we could have invoice items that are a percentage (either positive or negative) of the preceding line item, like the Windows version has.
