This option allows you to set individual product prices for customers. In other words, you can set a specific price for a specific product for a specific customer.
Click on 'Modules' then select 'Price Manager' from the drop down list, then 'Special Prices'.
Restrict to field 1: You can set the special price to apply to all customers, a particular customer using their account number, or a particular customer type.
Restrict to field 2: Set the special price to apply to all products, a category of products or an individual product using the product code.
Minimum Quantity: Applies the price based on the quantity. If you want to set price breaks, you can set a rule for a quantity of 1, then a new rule for a quantity of 10, and so on.
Start Date: Select the date the special price will apply from.
End Date: Set this a long time in the future unless you want it to it expire on a particular date.
Calculation: Set the special price based on a percentage or value in relation to the current price, cost price, sell price or contract price.
Click 'Save' to complete the set-up and then go ahead and test it.
Important Note: You need to set-up one Price Level to activate the Special Price level as being a 'special price' module, it will use the standard sell price if the the special price is set higher than it. To fix this, set-up a price level that is 100% or more of the standard price.
