Standard report sales by customer type detail is showing erroneous discount amounts

Welcome to the Community, kurt29.

The incorrect discount amounts shown in your report are sometimes caused by errors in individual transactions where the discount was recorded. QuickBooks pulls data directly from your sales transactions (invoices, sales receipts, etc.) to populate reports. If the discount on the transaction was entered incorrectly, you can manually update it.

Here’s how:

1. Go to the affected transaction by navigating to the Reports tab.
2. Open the transaction and scroll down to the discount field.
3. Check if the discount amount was entered incorrectly..
4. Update it to the correct discount amount ($300), then click Save and close.
5. Once saved, re-run your report to confirm that the changes were applied successfully.
