i have the following tariff scheme: the consumption of certain product is divided in consumption categories, for example
category 1: from 1 to 50, costs $10 each unit category 2: from 51 to 150, costs $11 each unit category 3: from 151 to 250, costs $12 each unit
i tried using pricelists but it doesn't work the way i need it:
if i consume 200 units pricelists give me a total of 200*12=$2400 instead i need the following calculation:
50 * 10 = $500 (first 50 units use cat1 price)
100 * 11 = $1100 (the next 100 units use cat2 price)
50 * 12 = $600 (the last 50 units use cat3 price)
total = $500+$1100+$600 = $2200
so, is there anyway to implement this?
