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?

Just compensate each price with the amount you are overcharging for the lower quantities.

A fixed price per unit for 51 and above will overcharge by $1 per unit for the first 50 ($50), so subtract $50.

A fixed price per unit for 151 and above will overcharge by $2 per unit for the first 50 ($100) and $1 per unit for the next 100 ($100), so subtract $200

Rules:

 No Min Qty: Price = Baseprice * ( 1 + 0 ) + 0
Min Qty  51: Price = Baseprice * ( 1 + .1 ) + -50
Min Qty 151: Price = Baseprice * ( 1 + .2 ) + -200

200 units = 200 x $12 minus 200 = $2,200

it doesn't work, the -50 or -200 terms are applied to every single unit in price calculation

Exactly. But - the calculations above correct for this by removing an amount equal to what was overcharged. For 51 units, the unit price is $11 per unit, but $50 is taken away, accounting for the first 50 units being only $10. All of the formulas charge the SAME unit price for every unit, then compensate for the overcharge by removing it (the last part of the calculation). Try it.

i tried your advice and i got the following result: if i sell up to 50 units everything is ok, but if i sell 51 i get a total of 51 * ((10 * 1.1) - 50) = 51 * (11 - 50) = −1989

Yes - you are correct. It won't work this way. The price in the pricelist is a UNIT price. Sorry - I don't know an easy way to support this, without working out all of the unit prices beforehand and having a pricelist with every possible quantity that can be sold.
