Let me share with you additional insights on how you can apply discounts in your invoice, @ubcgroupusa.

You're actually correct, the discount only applies to the preceding line in invoice. You can follow the steps provided by my colleague above if you want to apply discount to a specific line item.

Although, you also have the option to add a discount to all items on the invoice. All we need to do is to add a subtotal after the last line item, then enter the discount after the subtotal. This way, it will calculate the discounts to all of the line item on the invoice. Let me provide you the steps on how to create a subtotal.

1. Go to List and select Item List.
2. Click the Item drop-down in the bottom left corner, then select New. (CTRL + N)
3. In the TYPE drop-down, select Subtotal.
4. Enter the item name, then click OK.

You can now create an invoice and enter all the items, then add the subtotal after last item. Once done, you can now add the discount after the subtotal. Please see the screen shot below:

In addition, you can print or email the invoice after creating it. Simply click the Print icon or the Email icon.

You can also run the Open Invoices report to check your customer balances. Just to go Reports and select Customers & Receivables, then click Open Invoices.
