Good day, NEEL_SAPIENT.

You can use sub-total so you can apply a discount per line item. Here's how:

1. Go to the List menu and select Item List.
2. Press CTRL + N altogether in your keyboard.
3. Select Subtotal for Type.
4. Enter all other details.
5. Click OK.

Then, create a discount item if you haven't set it up yet. Just press Ctrl + N again and select Discount. 

After putting all items in the invoice, add the subtotal first before the discount. The, add more items you need in the transaction.
