Hi there, @Christine_Laing. 

Thanks for taking the time to follow along with the thread and sharing your concerns with us. 

To clarify, are you referring to the Customer Balance Detail report, as mentioned by my colleague above? If so, please know that there isn't a Paid Date section or column when creating an invoice or a payment in QuickBooks Desktop. This is the reason why the column is empty in the report. If you want to see the date when the payment was created, you may check the date/s under the Date column of the report. 

Additionally, the invoice shows as paid to show the payment date to indicate that a payment was made on that date. However, it's not a field. It's just a mark. Therefore, the payment date will reflect under the Date column beside the Payment. I also wanted to mention that the Paid Date column is not yet fully utilized by the system since this field is still unavailable on sales forms.

For further details about reporting in QuickBooks Desktop, check out Understand Reports.

Please let me know if you have any questions or concerns. I'm always around to lend a hand. Take care!
