Hello there. I'm here to give clarification your concern and guide you on how you can add classes in QuickBooks Desktop (QBDT).
There are no changes made when adding a class in QBDT. Although, you are unable to add class to your payment transactions. You can only use the class tracking for your deposit and for the following transactions:
- Invoice
- Sales receipt
- Estimate
- Sales order
- Statement Charges
- Refunds and credits
- Check
- Credit card charges
- Bill
- Purchase order
- Paycheck
Also, may I know what happen or the changes you noticed on your company file when you use the class tracking feature? That way, we can help you further.
