The following explains how to add the buy and sell price and stock value to a stock item. The buy price is the price we pay when purchasing the stock items from the supplier. The sell price is the default price the customer is going to pay for the item if they are not entitled to any promotions or discounts.
Usage
Open the stock item if the item is not already open.
Make sure you are in the Properties tab.
Click on the Edit button if not already in edit mode.
Set the Buy Price.
Set the Sell Price.
Add the Stock Value if this is a new stock item.
Click on the Save Stock Item button when finished making changes.
Notes
You can block update the buy price, sell price and stock value against multiple stock items, see How To Bulk Update Stock Items.
