PLU numbers are used to sell items at the cash register without scanning. They are used for items that a barcode is not warranted such as a bulky item that is too heavy to lift. Setting it up is very easy.
1: Open Stock Maintenance and look up the item.
2: Click on the "Prices" tab
3: Scroll to the far right on the pricing grid and you will see the "PLU" field.
4: Click EDIT and enter a number into the PLU field (for example, 101)
5: Click SAVE
Now, in the cash register, when you are ringing up a sale simply enters the PLU into the "price entry" box, and press ENTER and our point of sale will find the item instantly!
