Up to 6 price levels can be defined for each Inventory Item. These are entered within the Inventory window via Other Data > Prices.
Level 1 is the Sell price from the Main Window.
The Edit Description button will allow you to enter descriptions for each price level. Any change of the Description fields on the inventory window affects all the inventory windows.
On the Customer Window > Prices, you can define which price level the customer will be charged. Use the Edit button at the top of the window. If the level is left a 0, Level 1 will be used.
If a customer is set to a certain price level, and the entered inventory items shows a 0.00 for that price level, the user gets a message asking permission to us the level 1 price.
