Support QuickBooks Profit & Loss Reporting by Class#1868

The QuickBooks connector currently exposes only limited Class-related fields, such as credit_memos__classref and purchase_orders__classref. These fields do not allow users to attribute posted income and expense lines to a QuickBooks Class.

Please add support for Class-level financial reporting by exposing line-level ClassRef fields for posting transactions, including:

Bills
Purchases and Expenses
Vendor Credits
Journal Entries
Other relevant income and expense transactions

An alternative or complementary option would be to support the QuickBooks Profit and Loss report summarized by Class.

The expected output should allow users to build reports at this level:

Account × Class × Month × Amount

This would enable property-level, department-level, or entity-level Profit and Loss reporting directly from QuickBooks data.
