Can we have a Payment option with charges fees? as most of delivey company charges cost and % per order. this will be useful to check our net profit
Not 100% if it will let you do it, but have you tried setting up a “reverse” discount that can be added to the bill before checkout?
the other option that springs to mind is the “dining options” that allow for different “taxes” on eat in / eat out, you could probably achieve something with that.
