Hi is it possible to discount only the remainder of a bill after splitting?
I.e. say i have a bill of £100 and i receive £20 cash, leaving me with £80 outstanding, i then wish to offer a 10% discount on the remaining £80. Currently when i try and discount the remainder it calculates the percentage of the entire bill and applies a £10 discount, not the £8 discount as intended.
Is what im trying to do possible? Its needed for an loyalty scheme where we often have customers who have a nearly full loyalty card whose current purchase will entitle them to the discount. So we say to them pay the £20 to fill your card, then use your discount on the remainder.
