## Details of the inventory item in the delivery note

First select in the list the inventory item you want to add or modify in the delivery note (unless you have a barcode reader). Then fill in these fields:

- **Barcode**: if you have a barcode reader connected to the computer and leave the cursor in this field, when you pass the reader over the barcode of the inventory item it is entered automatically and the corresponding inventory item is selected in the list. If you tick **default option**, to the right of the field, the cursor is placed in this field every time you open the screen.
- **Quantity**: the quantity, in the order units the vendor supplies. The vendor's order units are configured on the [Add/Modify Vendors of the Inventory Item](https://docs.pizzagest.com/books/pizzagest-O9f/page/addmodify-vendors-of-the-inventory-item) screen.
- **Price**: the price per unit or the total, whichever appears on the delivery note. To the right of the field, select the option that applies: unit price or total price.
- **Discount**: if the vendor gives you a discount, enter it as a percentage or in euros and tick the option that applies: `%` or `€`.
- **Batch**: the batch number that appears on the delivery note.
- **Manufacturing date**: the manufacturing date that appears on the delivery note.
- **Expiry date**: the expiry date that appears on the delivery note.
- **Stockroom**: a field only for customers who have a Head Office and can choose between several stockrooms.
