Per client per product discount

I have a client that has discounts for specific products. I know I can have discount for a whole invoice but I need to set discount for only a few products on a invoice.

I do have Discount enabled under Settings > Invoice Design > Product Columns but the field is nowhere to be found when adding new product or new invoice.

Is it possible to have a per client per product discount. Or at least discount field when creating invoice?


You can enable the product discount feature on Settings > Product Settings
