Hi there, @Alimerraj.

Adding a transaction reference number to a credit card payment during Bill Payment is not available in QuickBooks Desktop (QBDT).

My colleague shared a workaround that allows you to include a reference number when creating a Bill.

Please note that when you're processing your Bill Payment, you cannot add or edit the Ref. No.

Keep me posted if you have any further questions or concerns. We are available 24/7 to further assist you.
