Revenue Growth and Revenue Control go hand-in hand. In organizations with many customers, products, price points, discount types or rebates, it is key to keep the net revenue under control. Net revenue being defined as Quantity * (Gross Price minus all discounts minus all off-invoice rebates minus all other monies flowing to the customer). If the company manages gross prices / list prices, but let's sales teams discount arbitrarily, then net revenue tends to tumble as discounts grow.
Pricing Simulation for sales people can be highly useful in many situations. It can help assess price increases, or simulate different profitability outcomes when applying different assumptions. It can also be useful when e.g. merging companies to see what different scenarios play out well for the merged company versus the customer.
