Hello Wenyu,

The bulk invoice import tool in QuickBooks Online does not currently have mapping fields for Class or Discount Line Items. However, If you're using QuickBooks Online Plus or Advanced, you can manually edit an imported invoice to include class or location.

Alternatively, for the most straightforward solution, just head over to the QuickBooks App Store. You'll find a third-party application there specifically designed for imports that will offer the mapping you need for both Class and Discount fields.
