The easiest way to sell an item is to scan its barcode at POS. This will create a new sale line for the item. You can also use the Sell Item button to manually key an item in. 

NOTE:  If scanning you can skip to step 4.

1. Open POS.
2. Select the customer and click the Sell Item button. A new sale line will appear.
   
    
3. Key in the item number or use the Find/New button to either search for the item or to enter a new item. The item details will appear on the sale line.
   
    
4. The fields on the right control pricing and discount:
   
    

   Retail	Retail price of this item; cannot be changed here
   % Disc	Percentage item is discounted from retail; you can edit this to apply a discount
   $ Disc	Dollar amount item is discounted from retail; you can edit this to apply a discount
   Price	Current selling price; you can edit this to set a selling price; discount will be automatically calculated
   Tax	Tax collected on this item as defined by your tax setup; cannot be changed
   Net	Price plus tax (i.e. "out-the-door price"); you can edit this to set a final price and the system will calculate other fields accordingly

5. Edit pricing as desired.
   NOTE:  When you update one pricing field all other fields re-calculate automatically.
    
6. Continue with sale or, if complete, enter payment details and click Done.
