Thanks for the additional input, @magnus1,

It looks like you're using a different software for your invoices. Our forum can assist you with concerns about QuickBooks. In your case, you will need to contact your service provider so they can walk you through the steps on how to set up the discount per line item.

However, if you have a QuickBooks account, the option to apply discounts per line item is currently unavailable. There are two options to add a reduction to customers invoices. First is MaryLurleenM's step to add a service item.

The second one is turning on the Discount feature to apply bulk discount on sales. Here's how:

1. Click the cogwheel icon then select Accounts and Settings.
2. Tap the Sales menu then Sales form content.
3. Mark the Discount checkbox then, hit Save and Done.
   

When processing the invoice, you will see a Discount field at the bottom of the transaction. See this:
