No need to duplicate an issue, @cradford open one on this already, 11814. @joshreeder, @jhk and I have already built it and it’s a contribution that’s planned. It relies on the Purchase Discounts PR (discussed here) and a soon-to be PR’d Indirect Expense.
It’s not strange that lots of US businesses need this (like @charlie-cook) and the sponsor of this code Evaqua Farms. @rmehta this is what I was talking about when I said I’d be stealing the best ideas from QuickBooks and make them work for ERPNext.
