Thanks for reaching out, @jkequipmentmd.
When choosing the date range for the report, make sure to include the time frame when the invoices were paid. Also, double-check that invoices are linked to the right income accounts.
As for the negative cash balance, ensure that there are no duplicate or misclassified transactions. You can refer to this guide on filtering or searching transactions in QBO: Search for transactions and other data in QuickBooks Online. This will help you narrow down list of entries by sorting them by date and amount, allowing you to identify any duplicates more easily.
You can also save your filters, so you won’t have to rerun the same report in the future.
