Paying invoices with discount terms. How to apply discount?

We get charged frieght as so many others which we separate out on the vendor invoice.  How do I get the discount to only go against the goods purchased and not against the freight?

Thanx in advace.  We have easily 30 vendor invoices a day!

How do I exclude shipping from the discount ... it is already setup as a separate account 

I Have this same issue! did you ever find a solution?

Thanks for joining in on this thread, HUNTER ENGINEERING.

I'd like to share some steps to help with your concern.

When you set a discount on a transaction, it will be applied to the subtotal. This means that the shipping is included.

While the option to exclude the discount from the shipping is unavailable, you can send a product suggestion to our product developers. They'll review this idea and might consider updating it in the future.

You can follow these steps to send feedback:

1. Go to the Gear located at the top.
2. Under Profile, click Feedback.

If you want to check the status of your request, you can click this link: Customer Feedback for QuickBooks Online.

In the meantime, you can add the discount as another line item. Let's create a discount item first by following these steps:

1. Go to Sales > Product and Services.
2. Click the New button.
3. Choose Non-inventory.
4. Enter the discount name in the Name field.
5. In the Income account field, select Discount given.
6. Select Non-taxable under the Sales tax category drop-down.
7. Hit Save and close.

Once done, you can add the discount item next to the item you want it to be applied. 

Here's how:

1. Go to + New > Invoice.
2. Select the customer from the Customer drop-down menu.
3. In the first line, add the item. 
4. On the second line, select the discount item you've created.
5. Enter the discount as a negative number in the Amount field.
6. Check the Subtotal and hit Save and close.
