Can Omni Price do multiple tier pricing?
Unfortuantely, it cannot do multiple tier pricing. If you have a product/item that you apply a 30% markup to, and you want a certain customer that orders that item to receive a 10% discount, it cannot first calculate the 30% markup, then calculate the 10% discount. You would need to offer that item to that specific customer at a 20% markup instead.
Another option for this type of scenario, would be to apply the 30% markup in GP pricing, then create an Omni Price contract where you can apply the 10% discount to specific customers for specific items/products.
