To link a price list to a customer please follow the steps below:
Go to Setup > Customers, search for the customer that you want to associate to a particular price list and under the "Actions" column click on Edit.
On the tab Price Lists select a price list for a particular type of inventory and save.
A single customer can have different price lists but keep in mind that the seasons must have different date ranges, and these cannot overlap.
Once you associate the price list to your customers the system will suggest the price on the screen depending on the type of inventory you selected: Prebook, Standing Orders, Order Entry and E-commerce.
