The Inventory Pricing Level tab is used to list all the assigned pricing levels for the selected inventory item in the Inventory Item form. This tab allows you to create an unlimited number of pricing levels based on Unit Measure and a minimum and maximum quantities that the customer purchases. Based on those parameters you will be able to give a customer a greater discount on the sales price for the more they purchase. For instance, you could setup the pricing levels so that if a customer purchased between 5 and 10 of a single item they would get a discount and anything over 10 items they would get an even larger discount. There is an enormous amount of flexibility in setting up inventory pricing levels.
Very Important: Keep in mind that in order for a customer to receive one of the Sales Prices setup in the Pricing Level form they must be purchasing the exact Item No, Unit Measure and order between the Min and Max quantities. If they order more than the Max set for one price level they will not get that price. So make sure if you want a price level to be between 5 and anything higher you enter a very large number in the Max field like 99999999. See: Adding Inventory Pricing Levels
