How do we determine volume discounts?
#2 - Work on price breaks at approximate sales numbers. Eg, a software provider for SME's, might have price breaks at 5 users and 10 users whereas a program sold to multinationals will have price breaks at 250 users etc.
#3 - Work out the maximum discount you will give and make that for the largest volume and then work your way backwards from there.
All the Best,
