Hello, @aborgardt. 

The customization process in the new invoice layout is slightly different from the previous experience. Let me guide you through the steps in removing the "Qty" and "Rate" from your invoice in the new layout. 

1. Go to the Gear icon.
2. Select Custom form styles.
3. Click on New style, then choose Invoice.
4. From the Design tab, enter the name of the template.
5. Select the Content tab.
6. Choose the middle section, and uncheck Quantity and Rate boxes.
7. Hit Done.
8. In the Custom form styles page, select the drop-down list beside Edit.
9. Select Make default.

After this, please see the image below for reference in applying the created form style: 

Alternatively, you can also choose to remove the quantity and rate fields in your sales forms. Here's how:

1. Go to the Gear icon.
2. Select Sales.
3. In the Product and services section, toggle off Track quantity and price/rate.
4. Select Save, then Done.
